Obesity

Weight loss after bariatric surgery was linked with visceral fat reduction as well as reduced blood pressure, fasting glucose, and left ventricular remodeling, based an imaging study in 213 patients.

“We found that ventricular function measured by strain imaging improved in both the left and right sides of the heart, but function measured in the traditional method using endocardial motion [in other words, ejection fraction] actually worsened,” senior investigator Barry A. Borlaug, MD, said in an interview.

Although previous studies have shown positive effects of weight loss on the heart after bariatric surgery, most have been short term and have not specifically examined the effects of visceral fat reduction, wrote the investigators.

“We are in the middle of an increasing epidemic of obesity worldwide, but particularly in the United States, where it is currently projected that one in two adults will be obese by 2030,” added Dr. Borlaug of Mayo Clinic, Rochester, Minn. “Heart failure with preserved ejection fraction (HFpEF) is growing in tandem, and numerous recent studies have shown that obesity is one of the strongest risk factors for developing HFpEF, and that the severity of HFpEF is intimately linked to excess body fat. This suggests that therapies to reduce body fat could improve the cardiac abnormalities that cause HFpEF, which was our focus in this study,” he explained.

In the study, published in the Journal of the American College of Cardiology, the researchers reviewed echocardiography data from 213 obese patients before and more than 180 days after bariatric surgery. They also measured abdominal visceral adipose tissue (VAT) of 52 patients via computed tomography. The average age of the patients was 54 years, the average body mass index was 45 kg/m², and 67% were women. Comorbidities included hypertension, diabetes, dyslipidemia, and obstructive sleep apnea.

The primary outcome was changes in cardiac structure and function.

After a median follow-up of 5.3 years, patients overall averaged a 23% reduction in body weight and a 22% reduction in BMI. In the 52 patients with abdominal scans, the VAT area decreased by 30% overall. Changes in left ventricular mass were significantly correlated to changes in the VAT.

Epicardial adipose thickness decreased by 14% overall. Left and right ventricular longitudinal strains improved at follow-up, but left atrial strain deteriorated, the researchers noted.

Although the mechanism of action remains unclear, the results suggest that left ventricular remodeling was associated with visceral adiposity rather than subcutaneous fat, the researchers wrote.

They also found that right ventricular strain was negatively correlated with VAT, but not with body weight or BMI.

“These findings suggest that weight loss, particularly reduction in visceral adiposity, benefits [right ventricular] structure and function in a manner akin to that observed in the [left ventricle],” the researchers noted.

Some surprises and limitations

Dr. Borlaug said he found some, but not all, of the results surprising. “Earlier studies had shown evidence for benefit from weight loss on cardiac structure and function, but had been limited by smaller sample sizes, shorter durations of evaluation, and variable methods used,” he said in an interview.

The findings that strain imaging showed both left and right ventricular function improved while EF declined “shows some of the problems with using EF, as it is affected by chamber size and geometry. We have previously shown that patients with HFpEF display an increase in fat around the heart, and this affects cardiac function and interaction between the left and right sides of the heart, so we expected to see that this fat depot would be reduced, and this was indeed the case,” Dr. Borlaug added.

In the current study, “visceral fat was most strongly tied to the heart remodeling in obesity, and changes in visceral fat were most strongly tied to improvements in cardiac structure following weight loss,” Dr. Borlaug told this news organization. “This further supports this concept that excess visceral fat plays a key role in HFpEF, especially in the abdomen and around the heart,” he said.

However, “The biggest surprise was the discordant effects in the left atrium,” Dr. Borlaug said. “Left atrial remodeling and dysfunction play a crucial role in HFpEF as well, and we expected that this would improve following weight loss, but in fact we observed that left atrial function deteriorated, and other indicators of atrial myopathy worsened, including higher estimates of left atrial pressures and increased prevalence of atrial fibrillation,” he said.

This difference emphasizes that weight loss may not address all abnormalities that lead to HFpEF, although a key limitation of the current study was the lack of a control group of patients with the same degree of obesity and no weight-loss intervention, and the deterioration in left atrial function might have been even greater in the absence of weight loss, Dr. Borlaug added.
 

Larger numbers support effects

Previous research shows that structural heart changes associated with obesity can be reversed through weight loss, but the current study fills a gap by providing long-term data in a larger sample than previously studied, wrote Paul Heidenreich, MD, of Stanford (Calif.) University in an accompanying editorial).

“There has been uncertainty regarding the prolonged effect of weight loss on cardiac function; this study was larger than many prior studies and provided a longer follow-up,” Dr. Heidenreich said in an interview.

“One unusual finding was that, while weight loss led to left ventricle reverse remodeling (reduction in wall thickness), the same effect was not seen for the left atrium; the left atrial size continued to increase,” he said. “I would have expected the left atrial changes to mirror the changes in the left ventricle,” he noted.

The findings support the greater cardiac risk of visceral vs. subcutaneous adipose tissue, and although body mass index will retain prognostic value, measures of central obesity are more likely predictors of cardiac structural changes and events and should be reported in clinical studies, Dr. Heidenreich wrote.

However, “We need a better understanding of the factors that influence left atrial remodeling and reverse remodeling,” Dr. Heidenreich told this news organization. “While left ventricular compliance and pressure play a role, there are other factors that need to be elucidated,” he said.

 

Studies in progress may inform practice

The current data call for further study to test novel treatments to facilitate weight loss in patients with HFpEF and those at risk for HFpEF, and some of these studies with medicines are underway, Dr. Borlaug said in the interview.

“Until such studies are completed, we will not truly understand the effects of weight loss on the heart, but the present data certainly provide strong support that patients who have obesity and HFpEF or are at risk for HFpEF should try to lose weight through lifestyle interventions,” he said. 

Whether the cardiac changes seen in the current study would be different with nonsurgical weight loss remains a key question because many obese patients are reluctant to undergo bariatric surgery, Dr. Borlaug said. “We cannot assess whether the effects would differ with nonsurgical weight loss, and this requires further study,” he added.

As for additional research, “Randomized, controlled trials of weight-loss interventions, with appropriate controls and comprehensive assessments of cardiac structure, function, and hemodynamics will be most informative,” said Dr. Borlaug. “Larger trials powered to evaluate cardiovascular outcomes such as heart failure hospitalization or cardiovascular death also are critically important to better understand the role of weight loss to treat and prevent HFpEF, the ultimate form of obesity-related heart disease,” he emphasized.

The study was supported in part by grants to lead author Dr. Hidemi Sorimachi of the Mayo Clinic from the Uehara Memorial Foundation, Japan, and to corresponding author Dr. Borlaug from the National Institutes of Health. Dr. Borlaug also disclosed previous grants from National Institutes of Health/National Heart, Lung, and Blood Institute, AstraZeneca, Corvia, Medtronic, GlaxoSmithKline, Mesoblast, Novartis, and Tenax Therapeutics; and consulting fees from Actelion, Amgen, Aria, Axon Therapies, Boehringer Ingelheim, Edwards Lifesciences, Eli Lilly, Imbria, Janssen, Merck, Novo Nordisk, and VADovations.

A mother’s consumption of ultra-processed foods appears to be related to an increased risk of overweight or obesity in her children, according to new research.

Among the 19,958 mother-child pairs studied, 12.4% of children developed obesity or overweight in the full analytic study group, and the offspring of those mothers who ate the most ultra-processed foods had a 26% higher risk of obesity/overweight (12.1 servings/day), compared with those with the lowest consumption (3.4 servings/day), report Andrew T. Chan, MD, MPH, professor of medicine at Harvard Medical School, Boston, and colleagues.

This study demonstrates the possible advantages of restricting ultra-processed food consumption among women and mothers who are in their reproductive years to potentially lower the risk of childhood obesity, the investigators note.

“These data support the importance of refining dietary recommendations and the development of programs to improve nutrition for women of reproductive age to promote offspring health,” they write in their article, published in BMJ.

“As a medical and public health community, we have to understand that the period of time in which a woman is carrying a child or ... the time when she is raising her children represents a unique opportunity to potentially intervene to affect both the health of the mother and also the health of the children,” Dr. Chan said in an interview.

It is important to address these trends both on an individual clinician level and on a societal level, noted Dr. Chan.

“This is a good opportunity to counsel patients about the potential linkage between their consumption of ultra-processed food for not just themselves but also their kids, and I think that added counseling and awareness may motivate individuals to think about their diets in a more favorable way,” he added.

But ultra-processed foods are affordable and convenient, and many communities are not able to easily access fresh and healthy foods, so “it is incumbent upon [clinicians] to make it a priority and to break down those social and economic barriers, which make it difficult to have healthy and less processed food,” Dr. Chan elaborated.
 

Assessment of maternal junk food intake during peri-pregnancy and childhood

Modern Western diets frequently include ultra-processed foods – such as packaged baked goods and snacks, fizzy drinks, and sugary cereals – which are linked to adult weight increase. The relationship between parental consumption of highly processed meals and offspring weight is, however, unclear across generations, the researchers note.

Hence, they set out to determine whether eating ultra-processed foods during peri-pregnancy and while raising children increased the risk of being overweight or having obesity among children and teens.

The study team assessed 14,553 mothers and their 19,958 children from the Growing Up Today Study (GUTS I and II) and Nurses’ Health Study II (NHS II) in the United States. Males accounted for 45% of the children in the study, and the children’s ages ranged from 7 to 17 years.

The NHS II is a continuing investigation following the lifestyle and health choices of over 100,000 female registered nurses in the United States in 1989, while the GUTS I involved about 17,000 children of the nurses in the NHS II. Participants in GUTS I filled out an initial lifestyle and health survey and were evaluated annually between 1997 and 2001 and every 2 years thereafter.  

Roughly 11,000 children from the NHS II were included in the GUTS II. The children were further evaluated in 2006, 2008, and 2011, as well as every 2 years thereafter.

Participants were followed until the children reached 18 years of age or experienced obesity and overweight onset. A subcohort consisted of 2,925 mother-child pairs with data on peri-pregnancy eating patterns.

Maternal intake of ultra-processed foods while raising children was linked with obesity or overweight in children. Moreover, compared with the lowest consumption cohort (3.4 servings/day), there was a 26% greater risk for the greatest maternal ultra-processed food intake cohort (12.1 servings/day) after adjusting for child’s sedentary time, ultra-processed food intake, physical activity, and established maternal risk factors.

Even though rates were elevated, ultra-processed food intake during pregnancy was not significantly linked to a higher risk of obesity or overweight in children (P for trend = .07).

Sex, birth weight, age, gestational age, or maternal body weight had no effect on these correlations either.

The study’s limitations include the fact that some of the children in the pairs were lost during follow-up; there may have been data misreporting, as the weight and diet measures were provided via self-reported questionnaires; and potential residual confounding given the observational study design, the researchers note.

Other limitations include that the mothers involved in the study came from similar socioeconomic backgrounds, had similar personal and familial educational statuses, and were primarily White, which limits the generalizability of these data to other ethnic groups, the authors add.

“Further studies are warranted to investigate specific biological mechanisms and socioeconomic determinants underlying the observed associations between maternal ultra-processed food intake and offspring overweight and obesity,” the researchers conclude.

The relationship between parental consumption of highly processed meals and offspring weight is, however, unclear across generations, the researchers note.

Hence, they set out to determine whether eating ultra-processed foods during peri-pregnancy and while raising children increased the risk of being overweight or having obesity among children and teens.

The study team assessed 14,553 mothers and their 19,958 children from the Growing Up Today Study (GUTS I and II) and Nurses’ Health Study II (NHS II) in the United States. Males accounted for 45% of the children in the study, and the children’s ages ranged from 7 to 17 years.

The NHS II is a continuing investigation following the lifestyle and health choices of over 100,000 female registered nurses in the United States in 1989, while the GUTS I involved about 17,000 children of the nurses in the NHS II. Participants in GUTS I filled out an initial lifestyle and health survey and were evaluated annually between 1997 and 2001 and every 2 years thereafter.  

Roughly 11,000 children from the NHS II were included in the GUTS II. The children were further evaluated in 2006, 2008, and 2011, as well as every 2 years thereafter.

Participants were followed until the children reached 18 years of age or experienced obesity and overweight onset. A subcohort consisted of 2,925 mother-child pairs with data on peri-pregnancy eating patterns.

Maternal intake of ultra-processed foods while raising children was linked with obesity or overweight in children. Moreover, compared with the lowest consumption cohort (3.4 servings/day), there was a 26% greater risk for the greatest maternal ultra-processed food intake cohort (12.1 servings/day) after adjusting for child’s sedentary time, ultra-processed food intake, physical activity, and established maternal risk factors.

Even though rates were elevated, ultra-processed food intake during pregnancy was not significantly linked to a higher risk of obesity or overweight in children (P for trend = .07).

Sex, birth weight, age, gestational age, or maternal body weight had no effect on these correlations either.

The study’s limitations include the fact that some of the children in the pairs were lost during follow-up; there may have been data misreporting, as the weight and diet measures were provided via self-reported questionnaires; and potential residual confounding given the observational study design, the researchers note.

Other limitations include that the mothers involved in the study came from similar socioeconomic backgrounds, had similar personal and familial educational statuses, and were primarily White, which limits the generalizability of these data to other ethnic groups, the authors add.

“Further studies are warranted to investigate specific biological mechanisms and socioeconomic determinants underlying the observed associations between maternal ultra-processed food intake and offspring overweight and obesity,” the researchers conclude.

New research suggests there may be better times during the day for eating and fasting. 

Eating earlier in the day may help you lose weight, and eating meals within a 10-hour window could improve blood sugar and cholesterol levels, according to two new studies published in Cell Metabolism.

“You have this internal biological clock that makes you better at doing different things at different times of the day,” Courtney Peterson, PhD, an associate professor of nutrition sciences at the University of Alabama at Birmingham, told NBC News. Dr. Peterson wasn’t involved with the studies.

“It seems like the best time for your metabolism, in most people, is the mid to late morning,” she said.

In one study, researchers found that eating later in the day made people hungrier during a 24-hour period, as compared with eating the same meals earlier in the day. Late eating also burned calories at a slower rate and led to fat tissue that stored more calories. Combined, the changes may increase the risk for obesity, the study authors found.

In another study, among firefighters as shift workers, researchers found that eating meals within a 10-hour window decreased the size of bad cholesterol particles, which could reduce risk factors for heart disease. The 10-hour eating window also improved blood pressure and blood sugar levels among those with health conditions such as diabetes, high blood pressure, and high cholesterol.

The two new studies confirm findings from previous studies that indicate humans may have an ideal eating window based on the body’s circadian rhythms, which regulate sleep and wake cycles and can affect appetite, metabolism, and blood sugar levels.

In the firefighter study, for instance, the 10-hour window appears to be a “sweet spot” for the body, the authors found. More severe restrictions, as found with many intermittent fasting diets, could be difficult for the body to maintain.

“When we think about 6 or 8 hours, you might see a benefit, but people might not stick to it for a long time,” Satchidananda Panda, PhD, one of the study authors and a professor at the Salk Institute, La Jolla, Calif., told NBC News.

The new studies had small sample sizes, though they offer insight for future research. In the first study, 16 people who were overweight or obese tried two eating plans for 24-hour periods. Some of them began eating an hour after their natural wake-up time, and others waited to begin eating until about 5 hours after waking up. They ate the same meals with the same calories and nutrients.

The researchers measured their hormone levels and found that eating later decreased the levels of leptin, which helps people to feel full. Eating later also doubled the odds that people felt hungry throughout the day. Those in the study who ate later in the day also had more cravings for starchy or salty foods, as well as meat and dairy, which are energy-dense foods.

The research team also found changes in fat tissue, which could lead to a higher chance of building up new fat cells and a lower chance of burning fat. Late eaters burned about 60 fewer calories than early eaters during the day.

“Your body processes calories differently when you eat late in the day. It tips the scale in favor of weight gain and fat gain,” Dr. Peterson said. “From this study, we can get pretty clear recommendations that people shouldn’t skip breakfast.”

The second study followed 137 firefighters in San Diego who ate a Mediterranean diet with fish, vegetables, fruit, and olive oil for 12 weeks. Among those, 70 firefighters ate during a 10-hour window, and the rest ate during a longer window, generally about 13 hours. They logged their meals in an app and wore devices to track blood sugar levels.

In the 10-hour group, most firefighters ate between 8 a.m. or 9 a.m. and 6 p.m. or 7 p.m. The time-restricted eating appeared to be linked with health benefits, such as less harmful cholesterol buildup and reduced heart disease. 

Among firefighters with risk factors for heart disease, such as high blood pressure and high blood sugar, the time-restricted eating decreased their blood pressure and blood sugar levels. 

The restricted window appears to allow the body to break down toxins and get rid of sodium and other things that can drive up blood pressure and blood sugar, the authors wrote.

During periods of fasting, “organs get some rest from digesting food so they can divert their energy toward repairing cells,” Dr. Panda said.

Eating earlier in the day may help you lose weight, and eating meals within a 10-hour window could improve blood sugar and cholesterol levels, according to two new studies published in Cell Metabolism.

A growing number of Americans with cardiovascular disease (CVD) have limited or uncertain access to food, results of a new study suggest.

An analysis of data from the National Health and Nutrition Examination Survey (NHANES) representing more than 300 million American adults found that, overall, 38.1% of people with cardiovascular disease were food insecure in 2017-2019.

Uphill battle

Johanna Contreras, MD, advanced heart failure and transplant cardiologist at the Mount Sinai Hospital, New York, treats food insecure cardiovascular patients in her practice and tries to educate them about good nutrition. But it is an uphill battle.

“A lot of my patients live in the South Bronx. They have hypertension, hypercholesterolemia, and there are no grocery stores where they can buy fresh vegetables. I talk to them about eating healthy. They tell me it’s impossible. The stores only have pre-packaged foods. So even in the South Bronx, even though it is in New York, it is very hard to get fresh food. And when it is available, it is very expensive,” Dr. Contreras told this news organization.

“Fresh pineapples can cost $8. A fast-food burger costs $3. So that is what they buy: It’s what they can afford. Even the store managers don’t want to stock fresh produce because it can spoil. They open stores, like Whole Foods, but in the more affluent neighborhoods. They should open one in poor neighborhoods,” she said.

Dr. Contreras says she spends much of her time educating her patients about good nutrition. She asks them to keep a food diary and analyzes the results at each visit.

“I look at what they eat, and I try to see how I can use this information in a good way. I advise them to use frozen foods, and avoid canned, because it is a lot healthier. I am pragmatic, because I know that if I tell my patients to eat salmon, for example, they aren’t going to be able to afford it, if they can even access it.”

She also informs them about relatively healthy fast-food choices.

“I tell them to order 100% fruit juice, water, or milk when they go to McDonalds or other fast-food places. So I think this study is very important. Food insecurity is a very important component of cardiovascular disease, and unfortunately, minority communities are where this occurs.”

Dr. Brandt and Dr. Contreras report no relevant financial relationships.

Bariatric surgery may raise the risk of developing epilepsy, new research suggests. Analyzing health records, investigators compared almost 17,000 patients who had undergone bariatric surgery with more than 620,000 individuals with obesity who had not undergone the surgery.

During a minimum 3-year follow-up period, the surgery group had a 45% higher risk of developing epilepsy than the nonsurgery group. Moreover, patients who had a stroke after their bariatric surgery were 14 times more likely to develop epilepsy than those who did not have a stroke.

“When considering having bariatric surgery, people should talk to their doctors about the benefits and risks,” senior investigator Jorge Burneo, MD, professor of neurology, biostatistics, and epidemiology and endowed chair in epilepsy at Western University, London, told this news organization.

“While there are many health benefits of weight loss, our findings suggest that epilepsy is a long-term risk of bariatric surgery for weight loss,” Dr. Burneo said.

The findings were published online in Neurology.
 

Unrecognized risk factor?

Bariatric surgery has become more common as global rates of obesity have increased. The surgery has been shown to reduce the risk for serious obesity-related conditions, the researchers note.

However, “in addition to the positive outcomes of bariatric surgery, several long-term neurological complications have also been identified,” they write.

One previous study reported increased epilepsy risk following gastric bypass. Those findings “suggest that bariatric surgery may be an unrecognized epilepsy risk factor; however, this possible association has not been thoroughly explored,” write the investigators.

Dr. Burneo said he conducted the study because he has seen patients with epilepsy in his clinic who were “without risk factors, with normal MRIs, who shared the history of having bariatric surgery before the development of epilepsy.”

The researchers’ primary objective was to “assess whether epilepsy risk is elevated following bariatric surgery for weight loss relative to a nonsurgical cohort of patients who are obese,” he noted.

The study used linked administrative health databases in Ontario, Canada. Patients were accrued from July 1, 2010, to Dec. 31, 2016, and were followed until Dec. 31, 2019. The analysis included 639,472 participants, 2.7% of whom had undergone bariatric surgery.

The “exposed” cohort consisted of all Ontario residents aged 18 years or older who had undergone bariatric surgery during the 6-year period (n = 16,958; 65.1% women; mean age, 47.4 years), while the “unexposed” cohort consisted of patients hospitalized with a diagnosis of obesity who had not undergone bariatric surgery (n = 622,514; 62.8% women; mean age, 47.6 years).

Patients with a history of seizures, epilepsy, epilepsy risk factors, prior brain surgery, psychiatric disorders, or drug or alcohol abuse/dependence were excluded from the analysis.

The researchers collected data on patients’ sociodemographic characteristics at the index date, as well as Charlson Comorbidity Index scores during the 2 years prior to index, and data regarding several specific comorbidities, such as diabetes mellitus, hypertension, sleep apnea, depression/anxiety, and cardiovascular factors.

The exposed and unexposed cohorts were followed for a median period of 5.8 and 5.9 person-years, respectively.
 

‘Unclear’ mechanisms

Before weighting, 0.4% of participants in the exposed cohort (n = 73) developed epilepsy, versus 0.2% of participants in the unexposed cohort (n = 1,260) by the end of the follow-up period.

In the weighted cohorts, there were 50.1 epilepsy diagnoses per 100,000 person-years, versus 34.1 per 100,000 person-years (rate difference, 16 per 100,000 person-years).

The multivariable analysis of the weighted cohort showed the hazard ratio for epilepsy cases that were associated with bariatric surgery was 1.45 (95% confidence interval, 1.35-1.56), after adjusting for sleep apnea and including stroke as a time-varying covariate.

Having a stroke during the follow-up period increased epilepsy 14-fold in the exposed cohort (HR, 14.03; 95% CI, 4.25-46.25).

The investigators note that they were unable to measure obesity status or body mass index throughout the study and that some obesity-related comorbidities “may affect epilepsy risk.”

In addition, Dr. Burneo reported that the study did not investigate potential causes and mechanisms of the association between bariatric surgery and epilepsy risk.

Hypotheses “include potential nutritional deficiencies, receipt of general anesthesia, or other unclear causes,” he said.

“Future research should investigate epilepsy as a potential long-term complication of bariatric surgery, exploring the possible effects of this procedure,” Dr. Burneo added.
 

Risk-benefit discussion

In a comment, Jacqueline French, MD, professor of neurology at NYU Grossman School of Medicine, and director of NYU’s Epilepsy Study Consortium, said she was “not 100% surprised by the findings” because she has seen in her clinical practice “a number of patients who developed epilepsy after bariatric surgery or had a history of bariatric surgery at the time they developed epilepsy.”

On the other hand, she has also seen patients who did not have a history of bariatric surgery and who developed epilepsy.

“I’m unable to tell if there is an association, although I’ve had it at the back of my head as a thought and wondered about it,” said Dr. French, who is also the chief medical and innovation officer at the Epilepsy Foundation. She was not involved with the study.

She noted that possible mechanisms underlying the association are that gastric bypass surgery leads to a “significant alteration” in nutrient absorption. Moreover, “we now know that the microbiome is associated with epilepsy” and that changes occur in the gut microbiome after bariatric surgery, Dr. French said.

There are two take-home messages for practicing clinicians, she added.

“Although the risk [of developing epilepsy] is very low, it should be presented as part of the risks and benefits to patients considering bariatric surgery,” she said.

“It’s equally important to follow up on the potential differences in these patients who go on to develop epilepsy following bariatric surgery,” said Dr. French. “Is there a certain metabolic profile or some nutrient previously absorbed that now is not absorbed that might predispose people to risk?”

This would be “enormously important to know because it might not just pertain to these people but to a whole other cohort of people who develop epilepsy,” Dr. French concluded.

The study was funded by the Ontario Ministry of Health and Ministry of Long-Term Care and by the Jack Cowin Endowed Chair in Epilepsy Research at Western University. Dr. Burneo holds the Jack Cowin Endowed Chair in Epilepsy Research at Western University. The other investigators and Dr. French have reported no relevant financial relationships.

“Future research should investigate epilepsy as a potential long-term complication of bariatric surgery, exploring the possible effects of this procedure,” Dr. Burneo added.
 

Risk-benefit discussion

In a comment, Jacqueline French, MD, professor of neurology at NYU Grossman School of Medicine, and director of NYU’s Epilepsy Study Consortium, said she was “not 100% surprised by the findings” because she has seen in her clinical practice “a number of patients who developed epilepsy after bariatric surgery or had a history of bariatric surgery at the time they developed epilepsy.”

On the other hand, she has also seen patients who did not have a history of bariatric surgery and who developed epilepsy.

“I’m unable to tell if there is an association, although I’ve had it at the back of my head as a thought and wondered about it,” said Dr. French, who is also the chief medical and innovation officer at the Epilepsy Foundation. She was not involved with the study.

She noted that possible mechanisms underlying the association are that gastric bypass surgery leads to a “significant alteration” in nutrient absorption. Moreover, “we now know that the microbiome is associated with epilepsy” and that changes occur in the gut microbiome after bariatric surgery, Dr. French said.

There are two take-home messages for practicing clinicians, she added.

“Although the risk [of developing epilepsy] is very low, it should be presented as part of the risks and benefits to patients considering bariatric surgery,” she said.

“It’s equally important to follow up on the potential differences in these patients who go on to develop epilepsy following bariatric surgery,” said Dr. French. “Is there a certain metabolic profile or some nutrient previously absorbed that now is not absorbed that might predispose people to risk?”

This would be “enormously important to know because it might not just pertain to these people but to a whole other cohort of people who develop epilepsy,” Dr. French concluded.

The study was funded by the Ontario Ministry of Health and Ministry of Long-Term Care and by the Jack Cowin Endowed Chair in Epilepsy Research at Western University.

Bariatric surgery may raise the risk of developing epilepsy, new research suggests. Analyzing health records, investigators compared almost 17,000 patients who had undergone bariatric surgery with more than 620,000 individuals with obesity who had not undergone the surgery.

During a minimum 3-year follow-up period, the surgery group had a 45% higher risk of developing epilepsy than the nonsurgery group. Moreover, patients who had a stroke after their bariatric surgery were 14 times more likely to develop epilepsy than those who did not have a stroke.

“When considering having bariatric surgery, people should talk to their doctors about the benefits and risks,” senior investigator Jorge Burneo, MD, professor of neurology, biostatistics, and epidemiology and endowed chair in epilepsy at Western University, London, told this news organization.

“While there are many health benefits of weight loss, our findings suggest that epilepsy is a long-term risk of bariatric surgery for weight loss,” Dr. Burneo said.

The findings were published online in Neurology.
 

Unrecognized risk factor?

Bariatric surgery has become more common as global rates of obesity have increased. The surgery has been shown to reduce the risk for serious obesity-related conditions, the researchers note.

However, “in addition to the positive outcomes of bariatric surgery, several long-term neurological complications have also been identified,” they write.

One previous study reported increased epilepsy risk following gastric bypass. Those findings “suggest that bariatric surgery may be an unrecognized epilepsy risk factor; however, this possible association has not been thoroughly explored,” write the investigators.

Dr. Burneo said he conducted the study because he has seen patients with epilepsy in his clinic who were “without risk factors, with normal MRIs, who shared the history of having bariatric surgery before the development of epilepsy.”

The researchers’ primary objective was to “assess whether epilepsy risk is elevated following bariatric surgery for weight loss relative to a nonsurgical cohort of patients who are obese,” he noted.

The study used linked administrative health databases in Ontario, Canada. Patients were accrued from July 1, 2010, to Dec. 31, 2016, and were followed until Dec. 31, 2019. The analysis included 639,472 participants, 2.7% of whom had undergone bariatric surgery.

The “exposed” cohort consisted of all Ontario residents aged 18 years or older who had undergone bariatric surgery during the 6-year period (n = 16,958; 65.1% women; mean age, 47.4 years), while the “unexposed” cohort consisted of patients hospitalized with a diagnosis of obesity who had not undergone bariatric surgery (n = 622,514; 62.8% women; mean age, 47.6 years).

Patients with a history of seizures, epilepsy, epilepsy risk factors, prior brain surgery, psychiatric disorders, or drug or alcohol abuse/dependence were excluded from the analysis.

The researchers collected data on patients’ sociodemographic characteristics at the index date, as well as Charlson Comorbidity Index scores during the 2 years prior to index, and data regarding several specific comorbidities, such as diabetes mellitus, hypertension, sleep apnea, depression/anxiety, and cardiovascular factors.

The exposed and unexposed cohorts were followed for a median period of 5.8 and 5.9 person-years, respectively.
 

‘Unclear’ mechanisms

Before weighting, 0.4% of participants in the exposed cohort (n = 73) developed epilepsy, versus 0.2% of participants in the unexposed cohort (n = 1,260) by the end of the follow-up period.

In the weighted cohorts, there were 50.1 epilepsy diagnoses per 100,000 person-years, versus 34.1 per 100,000 person-years (rate difference, 16 per 100,000 person-years).

The multivariable analysis of the weighted cohort showed the hazard ratio for epilepsy cases that were associated with bariatric surgery was 1.45 (95% confidence interval, 1.35-1.56), after adjusting for sleep apnea and including stroke as a time-varying covariate.

Having a stroke during the follow-up period increased epilepsy 14-fold in the exposed cohort (HR, 14.03; 95% CI, 4.25-46.25).

The investigators note that they were unable to measure obesity status or body mass index throughout the study and that some obesity-related comorbidities “may affect epilepsy risk.”

In addition, Dr. Burneo reported that the study did not investigate potential causes and mechanisms of the association between bariatric surgery and epilepsy risk.

Hypotheses “include potential nutritional deficiencies, receipt of general anesthesia, or other unclear causes,” he said.

“Future research should investigate epilepsy as a potential long-term complication of bariatric surgery, exploring the possible effects of this procedure,” Dr. Burneo added.

Ezetimibe given in combination with rosuvastatin has a beneficial effect on liver fat in people with nonalcoholic fatty liver disease (NAFLD), according results of a randomized, active-controlled trial.

The findings, which come from the investigator-initiated ESSENTIAL trial, are likely to add to the debate over whether or not the lipid-lowering combination could be of benefit beyond its effects in the blood.

“We used magnetic resonance imaging-derived proton density fat fraction [MRI-PDFF], which is highly reliable method of assessing hepatic steatosis,” Youngjoon Kim, PhD, one of the study investigators, said at the annual meeting of the European Association for the Study of Diabetes in Barcelona.

“It enables accurate, repeatable and reproducible quantitative assessment of liver fat over the entire liver,” observed Dr. Kim, who works at Severance Hospital, part of Yonsei University in Seoul.

He reported that there was a significant 5.8% decrease in liver fat following 24 weeks’ treatment with ezetimibe and rosuvastatin comparing baseline with end of treatment MRI-PDFF values; a drop that was significant (18.2% vs. 12.3%, P < .001).

Rosuvastatin monotherapy also reduced liver fat from 15.0% at baseline to 12.4% after 24 weeks; this drop of 2.6% was also significant (P = .003).

This gave an absolute mean difference between the two study arms of 3.2% (P = .02).
 

Rationale for the ESSENTIAL study

Dr. Kim observed during his presentation that NAFLD is burgeoning problem around the world. Ezetimibe plus rosuvastatin was a combination treatment already used widely in clinical practice, and there had been some suggestion that ezetimibe might have an effect on liver fat.

“Although the effect of ezetimibe on hepatic steatosis is still controversial, ezetimibe has been reported to reduce visceral fat and improve insulin resistance in several studies” Dr. Kim said.

“Recently, our group reported that the use of ezetimibe affects autophagy of hepatocytes and the NLRP3 [NOD-like receptors containing pyrin domain 3] inflammasome,” he said.

Moreover, he added, “ezetimibe improved NASH [nonalcoholic steatohepatitis] in an animal model. However, the effects of ezetimibe have not been clearly shown in a human study.”

Dr. Kim also acknowledged a prior randomized control trial that had looked at the role of ezetimibe in 50 patients with NASH, but had not shown a benefit for the drug over placebo in terms of liver fat reduction.
 

Addressing the Hawthorne effect

“The size of the effect by that might actually be more modest due to the Hawthorne effect,” said session chair Onno Holleboom, MD, PhD, of Amsterdam UMC in the Netherlands.

“What we observe in the large clinical trials is an enormous Hawthorne effect – participating in a NAFLD trial makes people live healthier because they have health checks,” he said.

“That’s a major problem for showing efficacy for the intervention arm,” he added, but of course the open design meant that the trial only had intervention arms; “there was no placebo arm.”
 

A randomized, active-controlled, clinician-initiated trial

The main objective of the ESSENTIAL trial was therefore to take another look at the potential effect of ezetimibe on hepatic steatosis and doing so in the setting of statin therapy.

In all, 70 patients with NAFLD that had been confirmed via ultrasound were recruited into the prospective, single center, phase 4 trial. Participants were randomized 1:1 to received either ezetimibe 10 mg plus rosuvastatin 5 mg daily or rosuvastatin 5 mg for up to 24 weeks.

Change in liver fat was measured via MRI-PDFF, taking the average values in each of nine liver segments. Magnetic resonance elastography (MRE) was also used to measure liver fibrosis, although results did not show any differences either from baseline to end of treatment values in either group or when the two treatment groups were compared.

Dr. Kim reported that both treatment with the ezetimibe-rosuvastatin combination and rosuvastatin monotherapy reduced parameters that might be associated with a negative outcome in NAFLD, such as body mass index and waist circumference, triglycerides, and LDL cholesterol. There was also a reduction in C-reactive protein levels in the blood, and interleulin-18. There was no change in liver enzymes.

Several subgroup analyses were performed indicating that “individuals with higher BMI, type 2 diabetes, insulin resistance, and severe liver fibrosis were likely to be good responders to ezetimibe treatment,” Dr. Kim said.

“These data indicate that ezetimibe plus rosuvastatin is a safe and effective therapeutic option to treat patients with NAFLD and dyslipidemia,” he concluded.

The results of the ESSENTIAL study have been published in BMC Medicine.

The study was funded by the Yuhan Corporation. Dr. Kim had no conflicts of interest to report. Dr. Holleboom was not involved in the study and had no conflicts of interest.

STOCKHOLM – Weight loss should be a co–primary management goal for type 2 diabetes in adults, according to a new comprehensive joint consensus report from the European Association for the Study of Diabetes and the American Diabetes Association.

And while metformin is still recommended as first-line therapy for patients with type 2 diabetes with no other comorbidities, the statement expands the indications for use of other agents or combinations of agents as initial therapy for subgroups of patients, as part of individualized and patient-centered decision-making.

Last updated in 2019, the new “Management of Hyperglycemia in Type 2 Diabetes” statement also places increased emphasis on social determinants of health, incorporates recent clinical trial data for cardiovascular and kidney outcomes for sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagonlike peptide–1 (GLP-1) agonists to broaden recommendations for cardiorenal protection, and discusses health behaviors such as sleep and sitting. It also targets a wider audience than in the past by addressing health system organization to optimize delivery of diabetes care.

The new statement was presented during a 90-minute session at the annual meeting of the EASD, with 12 of its 14 European and American authors as presenters. The document was simultaneously published in Diabetologia and Diabetes Care.

During the discussion, panel member Jennifer Brigitte Green, MD, commented: “Many of these recommendations are not new. They’re modest revisions of recommendations that have been in place for years, but we know that actual implementation rates of use of these drugs in patients with established comorbidities are very low.”

“I think it’s time for communities, health care systems, etc, to actually introduce these as expectations of care... to assess quality because unless it’s considered formally to be a requirement of care I just don’t think we’re going to move that needle very much,” added Dr. Green, who is professor of medicine at Duke University, Durham, N.C.

Vanita R. Aroda, MD, of the division of endocrinology, diabetes, and hypertension at Brigham and Women’s Hospital, Boston, commented: “In the past, sometimes these recommendations created fodder for debate, but I don’t think this one will. It’s just really solidly evidence based, with the rationales presented throughout, including the figures. I think just having very clear evidence-based directions should support their dissemination and use.”
 

Weight management plays a prominent role in treatment

In an interview, writing panel cochair John B. Buse, MD, PhD, said: “We are saying that the four major components of type 2 diabetes care are glycemic management, cardiovascular risk management, weight management, and prevention of end-organ damage, particularly with regard to cardiorenal risk.”

“The weight management piece is much more explicit now,” said Dr. Buse, director of the Diabetes Center at the University of North Carolina at Chapel Hill.

He noted that recent evidence from the intensive lifestyle trial DiRECT, conducted in the United Kingdom, the bariatric surgery literature, and the emergence of potent weight-loss drugs have meant that “achieving 10%-15% body weight loss is now possible.

“So, aiming for remission is something that might be attractive to patients and providers. This could be based on weight management, with the [chosen] method based on shared decision-making.”

According to the new report: “Weight loss of 5%-10% confers metabolic improvement; weight loss of 10%-15% or more can have a disease-modifying effect and lead to remission of diabetes, defined as normal blood glucose levels for 3 months or more in the absence of pharmacological therapy in a 2021 consensus report.”

“Weight loss may exert benefits that extend beyond glycemic management to improve risk factors for cardiometabolic disease and quality of life,” it adds.
 

Individualization featured throughout

The report’s sections cover principles of care, including the importance of diabetes self-management education and support and avoidance of therapeutic inertia. Detailed guidance addresses therapeutic options including lifestyle, weight management, and pharmacotherapy for treating type 2 diabetes.

Another entire section is devoted to personalizing treatment approaches based on individual characteristics, including new evidence from cardiorenal outcomes studies for SGLT2 inhibitors and GLP-1 agonists that have come out since the last consensus report.

The document advises: “Consider initial combination therapy with glucose-lowering agents, especially in those with high [hemoglobin] A1c at diagnosis (that is, > 70 mmol/mol [> 8.5%]), in younger people with type 2 diabetes (regardless of A1c), and in those in whom a stepwise approach would delay access to agents that provide cardiorenal protection beyond their glucose-lowering effects.”
 

Designed to be used and user-friendly

Under the “Putting it all together: strategies for implementation” section, several lists of “practical tips for clinicians” are provided for many of the topics covered.

A series of colorful infographics are included as well, addressing the “decision cycle for person-centered glycemic management in type 2 diabetes,” including a chart summarizing characteristics of available glucose-lowering medications, including cardiorenal protection.

Also mentioned is the importance of 24-hour physical behaviors (including sleep, sitting, and sweating) and the impact on cardiometabolic health, use of a “holistic person-centered approach” to type 2 diabetes management, and an algorithm on insulin use.

Dr. Buse has financial ties to numerous drug and device companies. Dr. Green is a consultant for AstraZeneca, Pfizer, Boehringer Ingelheim/Lilly, Bayer, Sanofi, Anji, Vertex/ICON, and Valo. Dr. Aroda has served as a consultant for Applied Therapeutics, Duke, Fractyl, Novo Nordisk, Pfizer, and Sanofi.

STOCKHOLM – Weight loss should be a co–primary management goal for type 2 diabetes in adults, according to a new comprehensive joint consensus report from the European Association for the Study of Diabetes and the American Diabetes Association.

And while metformin is still recommended as first-line therapy for patients with type 2 diabetes with no other comorbidities, the statement expands the indications for use of other agents or combinations of agents as initial therapy for subgroups of patients, as part of individualized and patient-centered decision-making.

Last updated in 2019, the new “Management of Hyperglycemia in Type 2 Diabetes” statement also places increased emphasis on social determinants of health, incorporates recent clinical trial data for cardiovascular and kidney outcomes for sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagonlike peptide–1 (GLP-1) agonists to broaden recommendations for cardiorenal protection, and discusses health behaviors such as sleep and sitting. It also targets a wider audience than in the past by addressing health system organization to optimize delivery of diabetes care.

The new statement was presented during a 90-minute session at the annual meeting of the EASD, with 12 of its 14 European and American authors as presenters. The document was simultaneously published in Diabetologia and Diabetes Care.

During the discussion, panel member Jennifer Brigitte Green, MD, commented: “Many of these recommendations are not new. They’re modest revisions of recommendations that have been in place for years, but we know that actual implementation rates of use of these drugs in patients with established comorbidities are very low.”

“I think it’s time for communities, health care systems, etc, to actually introduce these as expectations of care... to assess quality because unless it’s considered formally to be a requirement of care I just don’t think we’re going to move that needle very much,” added Dr. Green, who is professor of medicine at Duke University, Durham, N.C.

Vanita R. Aroda, MD, of the division of endocrinology, diabetes, and hypertension at Brigham and Women’s Hospital, Boston, commented: “In the past, sometimes these recommendations created fodder for debate, but I don’t think this one will. It’s just really solidly evidence based, with the rationales presented throughout, including the figures. I think just having very clear evidence-based directions should support their dissemination and use.”
 

Weight management plays a prominent role in treatment

In an interview, writing panel cochair John B. Buse, MD, PhD, said: “We are saying that the four major components of type 2 diabetes care are glycemic management, cardiovascular risk management, weight management, and prevention of end-organ damage, particularly with regard to cardiorenal risk.”

“The weight management piece is much more explicit now,” said Dr. Buse, director of the Diabetes Center at the University of North Carolina at Chapel Hill.

He noted that recent evidence from the intensive lifestyle trial DiRECT, conducted in the United Kingdom, the bariatric surgery literature, and the emergence of potent weight-loss drugs have meant that “achieving 10%-15% body weight loss is now possible.

“So, aiming for remission is something that might be attractive to patients and providers. This could be based on weight management, with the [chosen] method based on shared decision-making.”

According to the new report: “Weight loss of 5%-10% confers metabolic improvement; weight loss of 10%-15% or more can have a disease-modifying effect and lead to remission of diabetes, defined as normal blood glucose levels for 3 months or more in the absence of pharmacological therapy in a 2021 consensus report.”

“Weight loss may exert benefits that extend beyond glycemic management to improve risk factors for cardiometabolic disease and quality of life,” it adds.
 

Individualization featured throughout

The report’s sections cover principles of care, including the importance of diabetes self-management education and support and avoidance of therapeutic inertia. Detailed guidance addresses therapeutic options including lifestyle, weight management, and pharmacotherapy for treating type 2 diabetes.

Another entire section is devoted to personalizing treatment approaches based on individual characteristics, including new evidence from cardiorenal outcomes studies for SGLT2 inhibitors and GLP-1 agonists that have come out since the last consensus report.

The document advises: “Consider initial combination therapy with glucose-lowering agents, especially in those with high [hemoglobin] A1c at diagnosis (that is, > 70 mmol/mol [> 8.5%]), in younger people with type 2 diabetes (regardless of A1c), and in those in whom a stepwise approach would delay access to agents that provide cardiorenal protection beyond their glucose-lowering effects.”
 

Designed to be used and user-friendly

Under the “Putting it all together: strategies for implementation” section, several lists of “practical tips for clinicians” are provided for many of the topics covered.

A series of colorful infographics are included as well, addressing the “decision cycle for person-centered glycemic management in type 2 diabetes,” including a chart summarizing characteristics of available glucose-lowering medications, including cardiorenal protection.

Also mentioned is the importance of 24-hour physical behaviors (including sleep, sitting, and sweating) and the impact on cardiometabolic health, use of a “holistic person-centered approach” to type 2 diabetes management, and an algorithm on insulin use.

Children born to women who develop diabetes either before or during their pregnancy could be at risk for developing attention-deficit/hyperactivity disorder, data from a large multinational cohort study appear to show.

Considering more than 4.5 million mother-child pairs, it was found that children whose mothers had diabetes around the time of their pregnancy were 16% more likely to have ADHD diagnosed than were those whose mothers did not.

An increased risk was seen regardless of the type of diabetes, and regardless of whether or not the diabetes was present before or appeared during the pregnancy.

“We found a small increased risk of ADHD in children born to mothers with diabetes, including pregestational diabetes and gestational diabetes,” Carolyn Cesta, PhD, reported at the annual meeting of the European Association for the Study of Diabetes.

Dr. Cesta, a postdoctoral researcher in the Centre for Pharmacoepidemiology at the Karolinska Institutet in Stockholm noted that the effect sizes seen were lower than had been reported previously.

“This may be because we adjusted for a large number of covariates, including maternal ADHD and psychiatric disorders,” Dr. Cesta said.

ADHD and diabetes

“Previous studies have reported an increase in the risk of ADHD in children born to mothers with diabetes,” explained Dr. Cesta.

However, “these studies have been limited by the use of self-reported data, small sample sizes, lack of adjustment for important confounders, and they’re often limited to [White] populations,” she added. “There’s a lot of heterogeneity between these studies,” she said.

To try to iron out the differences seen in the prior studies, Dr. Cesta and associates looked at data from several databases based in Hong Kong (Clinical Data Analysis and Reporting System), four Nordic countries (Population Health Registers for Finland, Iceland, Norway, and Sweden), and Taiwan (National Health Insurance Database).

To create the matched mother-child pairs, the databases were searched to find women who had children born between 2001 and 2018, and who had follow-up data available up to 2020 on not only their diabetes status and child’s ADHD status, but also other parameters, such as other maternal diagnoses, maternal medications, and a host of sociodemographic factors.

More than 24 potentially confounding or covariates were considered in the analysis, which used Cox proportional hazard regression modeling and propensity score analysis to calculate hazard ratios with 95% confidence intervals.

“We looked at whether [mothers] had a diagnosis of ADHD themselves, or other psychiatric disorders, because there is high heritability for these disorders,” Dr. Cesta said, indicating that all bases had endeavored to be covered.

Main findings

Results showed some differences in the prevalence of diabetes and ADHD between the three cohorts used in the analysis. The prevalence of any maternal diabetes ranged from 8.8% in the Hong Kong cohort to 3.3% in the Taiwan cohort, with a prevalence of 6.8% for the Nordic cohort.

Rates of pregestational diabetes were lowest in the Taiwan and Hong Kong cohorts, at 0.2% and 0.5%, respectively, and 2.2% in the Nordic cohort. Gestational diabetes rates were a respective 3.1%, 7.8%, and 4.6%.

The highest rate of ADHD in children was seen in the Taiwan cohort, at 9.6%, followed by 4.2% for the Hong Kong cohort, and 2.6% for the Nordic cohort.

The hazard ratio for having childhood ADHD was 1.16 when comparing any maternal diabetes to no maternal diabetes, 1.40 comparing mothers with and without pregestational diabetes, and a respective 1.36 and 1.37 comparing those with and without type 1 diabetes, and those with and without type 2 diabetes.

The HR for childhood ADHD comparing mothers with and without gestational diabetes was 1.13.

“Within the analysis for gestational diabetes, we had enough numbers to look at siblings that are discordant for maternal gestational diabetes,” Dr. Cesta said. Essentially “we’re comparing two siblings from the same mother, one that was exposed to gestational diabetes, one that wasn’t,” she explained.

Interestingly there was no association between ADHD and maternal gestational diabetes in the sibling analysis (HR, 1.0).

“When it comes to gestational diabetes, the evidence from our sibling analysis indicate that the association may actually be confounded by shared genetics and environmental factors,” said Dr. Cesta.

“So, future studies should explore the role of specific genetic factors in glycemic control during pregnancy and the relationship between maternal diabetes and ADHD.”

Answering long-standing questions

These data will help a lot in answering questions that clinicians have been asking themselves a long time, commented Jardena Puder, MD, who chaired the session.

“It still remains a bit puzzling that genetic and environmental factors could be responsible, if you see the same effect in type 1 [diabetes], and in type 2 [diabetes], and gestational diabetes,” said Dr. Puder, who is an endocrinologist and diabetologist at the woman-mother-child department at the Vaud University Hospital Center, Lausanne, Switzerland.

Type 1 and type 2 are “very distinct” in terms of the genetic and environmental factors involved, “so, the fact that you see [the effect] in both remains a bit puzzling,” said Dr. Puder.

“I wish we had the numbers to be able to do the sibling analysis for type 1 and type 2, just to see if we could tease anything out,” said Dr. Cesta.

“I do think this is part of the bigger question of what the relationship is between, like, metabolic disorders and psychiatric disorders, because even outside of pregnancy, we see that there’s often a comorbidity with them. So, it’s a good point.”

The next step is to look at the role of treatment and what effects glycemic control might have on the small, but still apparent, association between maternal diabetes and ADHD.

The study had multiple funders including the Hong Kong Research Grant Council, NordForsk, the Research Council of Norway, the Norwegian ADHD Research Network, the Hong Kong Innovation and Technology Commission, and European Horizon 2020.

Dr. Cesta had no conflicts of interest to disclose. Dr. Puder chaired the session in which the findings were presented and made no specific disclosures.

Formulas for toddlers are a burgeoning business in the United States: Sales of the drinks more than doubled in recent years as companies convinced parents that their little ones needed the liquid boost. But many experts warn that these products, designed for children ages 1-3, fill no nutritional needs beyond what is available in a typical toddler diet, are subject to less regulation than infant formula, and are expensive.

In addition, some parents feed the toddler versions to infants even though they do not meet federal standards for infant formula and may not provide babies with adequate nutrients to sustain their growth.

Pediatricians and federal health officials say that when most children turn 1, they can begin drinking cow milk or an unsweetened plant-based milk substitute. In a 2019 “consensus” statement, the American Academy of Pediatrics and other health and nutrition organizations recommended against using toddler formulas, saying “they offer no unique nutritional value beyond what could be obtained with healthy foods; furthermore, they may contribute added sugars to the diet.” The toddler formulas often contain sweeteners and fats that add calories.

Some of the same companies that produce infant formula – including Enfamil, Gerber, and Similac – also make toddler formulas, as do some smaller, boutique brands that advertise that they have organic or other special qualities. Toddler formulas are available nearly everywhere infant formulas are sold and are marketed as providing extra nutrients to help children’s brain, immune system, and eye development, among other benefits. They are different from medical formulas prescribed for children with specific needs.

A 2020 study found that sales of toddler formula in the United States rose to $92 million in 2015 from $39 million in 2006.

Parents are often confused by the marketing for the formulas, according to a study led by Jennifer Harris, PhD, a marketing and public health researcher at the University of Connecticut, Hartford. She found that 60% of caregivers falsely believed toddler formulas have nutrients that toddlers can’t get from other foods.

Anthony Porto, MD, MPH, a pediatric gastroenterologist and pediatrics professor at Yale University, New Haven, Conn., said he is concerned these products could be giving toddlers more nutrients and calories than they need. Unlike what’s designed for infants, toddler formula has no nutritional regulations: Experts say standardizing a supplement to toddlers’ diets is impossible because no two children are alike.

In focus groups, Dr. Harris said, parents report feeding their children toddler formula to fill nutritional gaps when a child isn’t eating enough, a common concern among parents.

“Infants are often voracious eaters,” said Stephen Daniels, MD, chair of pediatrics at Children’s Hospital Colorado, Aurora. But at around a year of age, children’s growth plateaus, he said, and “they’re suddenly not hungry in the way they used to be anymore.” That can worry parents, he added, but “it’s a completely normal phenomenon.”

If parents have concerns about their children’s diet, Dr. Daniels said, they should consult a pediatrician or family doctor.

Blanche Lincoln, president of the Infant Nutrition Council of America, which represents the makers of Enfamil, Gerber, Similac, and store brands, said in an email that the toddler formulas can be helpful because they can fill “nutritional gaps during this period of transition to table foods.” Ms. Lincoln, a former U.S. senator from Arkansas, said the drinks “help contribute to the specific nutritional needs of toddlers by providing energy and important nutrients, as well as essential vitamins and minerals during this important period of growth and development.”

But toddler formula isn’t being ingested by toddlers alone – it’s also being fed to infants. In a recent study, Dr. Porto and colleagues found that 5% of infants’ parents reported giving their babies drinks marketed for the older age group. And Dr. Harris’ research indicated that 22% of parents of infants older than 6 months had fed their babies toddler formula in the previous month. Both studies were conducted before the recent infant formula shortage, which may have exacerbated the problem.

“Infant formulas and toddler formulas tend to be next to each other in the supermarket,” Dr. Harris said. “They look similar, but the toddler formulas are cheaper than the infant formulas. So people confuse them, and they grab the wrong one. Or they think: ‘Oh, this one is less expensive. I’ll get this one instead.’ ”

According to an email from Food and Drug Administration spokesperson Lindsay Haake, toddler drinks do not meet the definition of infant formula, so they are not subject to the same requirements. That means they do not have to undergo the clinical trials and pathogen safety testing that the infant versions do. “Unlike infant formulas, toddler formulas are not necessary to meet the nutritional needs of their intended consumers,” Ms. Haake said.

In a statement to KHN, the Infant Nutrition Council of America said: “Toddler drinks have a distinctive use and nutritional makeup from infant formula; the two are not interchangeable. The labeling of toddler nutritional drinks explicitly identifies the product as a toddler drink intended for children 12 months and older on the front of the package label.”

However, several expensive toddler formula brands made by smaller companies – often advertised as being made from goat milk, A2 whole milk (which lacks one common milk protein), or vegan ingredients that aren’t soy – do meet nutritional requirements for infants, and some advertise that.

Dr. Harris argued that this confuses parents, too, and shouldn’t be allowed. Just because a toddler formula has the nutritional ingredients required by the FDA for infant formula doesn’t mean it has met the other tests required of infant formula.

Federal regulators have not forced any of the companies to withdraw those products. In an email, FDA spokesperson Marianna Naum said: “The FDA does not comment on potential compliance actions.”

One company, Nature’s One, whose toddler formulas are named “Baby’s Only,” received warning letters a decade ago from the FDA about marketing them for infants. That case was closed in 2016. The company’s website says that Baby’s Only formula “meets nutrient requirements for infant” and that “Baby’s Only Organic® can be served up to 3 years of age.” Critics say that language implies the formula is fine for babies younger than 1. The company’s website and its Instagram account feature customer testimonials from parents who report feeding the formula to their infants, as well as pictures of infants drinking it.

Jay Highman, CEO and president of Nature’s One, said that Baby’s Only is clearly labeled as a toddler formula and that the back of the can states that “Baby’s Only is intended for a toddler 1 year of age or older OR when directed by a health care professional.” He also said that since the company launched in 1999, its formulas have met all the nutritional, manufacturing, and safety standards required of infant formula even though they don’t have to. “We behaved like we are an infant formula, but we were selling it as a toddler formula.”

He said that the clinical trials required by the FDA are a huge barrier to bringing a new infant formula to market and that many other countries don’t require a clinical trial. Baby’s Only recently completed a clinical trial, and the company expects to be able to sell it as an infant formula soon.

Yet pediatricians and nutritional experts continue to caution parents about using the toddler drinks. “There’s no question that infant formula is very important in the first year of life,” Dr. Daniels said. But he doesn’t recommend the toddler version “because it’s not that useful, because it’s confusing, because it’s expensive.”

Together with Policy Analysis and Polling, KHN is one of the three major operating programs at KFF (Kaiser Family Foundation).

So people confuse them, and they grab the wrong one. Or they think: ‘Oh, this one is less expensive. I’ll get this one instead.’ ”

According to an email from Food and Drug Administration spokesperson Lindsay Haake, toddler drinks do not meet the definition of infant formula, so they are not subject to the same requirements. That means they do not have to undergo the clinical trials and pathogen safety testing that the infant versions do. “Unlike infant formulas, toddler formulas are not necessary to meet the nutritional needs of their intended consumers,” Ms. Haake said.

In a statement to KHN, the Infant Nutrition Council of America said: “Toddler drinks have a distinctive use and nutritional makeup from infant formula; the two are not interchangeable. The labeling of toddler nutritional drinks explicitly identifies the product as a toddler drink intended for children 12 months and older on the front of the package label.”

However, several expensive toddler formula brands made by smaller companies – often advertised as being made from goat milk, A2 whole milk (which lacks one common milk protein), or vegan ingredients that aren’t soy – do meet nutritional requirements for infants, and some advertise that.

Dr. Harris argued that this confuses parents, too, and shouldn’t be allowed. Just because a toddler formula has the nutritional ingredients required by the FDA for infant formula doesn’t mean it has met the other tests required of infant formula.

Federal regulators have not forced any of the companies to withdraw those products. In an email, FDA spokesperson Marianna Naum said: “The FDA does not comment on potential compliance actions.”

One company, Nature’s One, whose toddler formulas are named “Baby’s Only,” received warning letters a decade ago from the FDA about marketing them for infants. That case was closed in 2016. The company’s website says that Baby’s Only formula “meets nutrient requirements for infant” and that “Baby’s Only Organic® can be served up to 3 years of age.” Critics say that language implies the formula is fine for babies younger than 1. The company’s website and its Instagram account feature customer testimonials from parents who report feeding the formula to their infants, as well as pictures of infants drinking it.

Jay Highman, CEO and president of Nature’s One, said that Baby’s Only is clearly labeled as a toddler formula and that the back of the can states that “Baby’s Only is intended for a toddler 1 year of age or older OR when directed by a health care professional.” He also said that since the company launched in 1999, its formulas have met all the nutritional, manufacturing, and safety standards required of infant formula even though they don’t have to. “We behaved like we are an infant formula, but we were selling it as a toddler formula.”

He said that the clinical trials required by the FDA are a huge barrier to bringing a new infant formula to market and that many other countries don’t require a clinical trial. Baby’s Only recently completed a clinical trial, and the company expects to be able to sell it as an infant formula soon.

Yet pediatricians and nutritional experts continue to caution parents about using the toddler drinks. “There’s no question that infant formula is very important in the first year of life,” Dr. Daniels said. But he doesn’t recommend the toddler version “because it’s not that useful, because it’s confusing, because it’s expensive.”

Formulas for toddlers are a burgeoning business in the United States: Sales of the drinks more than doubled in recent years as companies convinced parents that their little ones needed the liquid boost. But many experts warn that these products, designed for children ages 1-3, fill no nutritional needs beyond what is available in a typical toddler diet, are subject to less regulation than infant formula, and are expensive.

In addition, some parents feed the toddler versions to infants even though they do not meet federal standards for infant formula and may not provide babies with adequate nutrients to sustain their growth.

Pediatricians and federal health officials say that when most children turn 1, they can begin drinking cow milk or an unsweetened plant-based milk substitute. In a 2019 “consensus” statement, the American Academy of Pediatrics and other health and nutrition organizations recommended against using toddler formulas, saying “they offer no unique nutritional value beyond what could be obtained with healthy foods; furthermore, they may contribute added sugars to the diet.” The toddler formulas often contain sweeteners and fats that add calories.

Some of the same companies that produce infant formula – including Enfamil, Gerber, and Similac – also make toddler formulas, as do some smaller, boutique brands that advertise that they have organic or other special qualities. Toddler formulas are available nearly everywhere infant formulas are sold and are marketed as providing extra nutrients to help children’s brain, immune system, and eye development, among other benefits. They are different from medical formulas prescribed for children with specific needs.

A 2020 study found that sales of toddler formula in the United States rose to $92 million in 2015 from $39 million in 2006.

Parents are often confused by the marketing for the formulas, according to a study led by Jennifer Harris, PhD, a marketing and public health researcher at the University of Connecticut, Hartford. She found that 60% of caregivers falsely believed toddler formulas have nutrients that toddlers can’t get from other foods.

Anthony Porto, MD, MPH, a pediatric gastroenterologist and pediatrics professor at Yale University, New Haven, Conn., said he is concerned these products could be giving toddlers more nutrients and calories than they need. Unlike what’s designed for infants, toddler formula has no nutritional regulations: Experts say standardizing a supplement to toddlers’ diets is impossible because no two children are alike.

In focus groups, Dr. Harris said, parents report feeding their children toddler formula to fill nutritional gaps when a child isn’t eating enough, a common concern among parents.

“Infants are often voracious eaters,” said Stephen Daniels, MD, chair of pediatrics at Children’s Hospital Colorado, Aurora. But at around a year of age, children’s growth plateaus, he said, and “they’re suddenly not hungry in the way they used to be anymore.” That can worry parents, he added, but “it’s a completely normal phenomenon.”

If parents have concerns about their children’s diet, Dr. Daniels said, they should consult a pediatrician or family doctor.

Blanche Lincoln, president of the Infant Nutrition Council of America, which represents the makers of Enfamil, Gerber, Similac, and store brands, said in an email that the toddler formulas can be helpful because they can fill “nutritional gaps during this period of transition to table foods.” Ms. Lincoln, a former U.S. senator from Arkansas, said the drinks “help contribute to the specific nutritional needs of toddlers by providing energy and important nutrients, as well as essential vitamins and minerals during this important period of growth and development.”

But toddler formula isn’t being ingested by toddlers alone – it’s also being fed to infants. In a recent study, Dr. Porto and colleagues found that 5% of infants’ parents reported giving their babies drinks marketed for the older age group. And Dr. Harris’ research indicated that 22% of parents of infants older than 6 months had fed their babies toddler formula in the previous month. Both studies were conducted before the recent infant formula shortage, which may have exacerbated the problem.

“Infant formulas and toddler formulas tend to be next to each other in the supermarket,” Dr. Harris said. “They look similar, but the toddler formulas are cheaper than the infant formulas. So people confuse them, and they grab the wrong one. Or they think: ‘Oh, this one is less expensive. I’ll get this one instead.’ ”

STOCKHOLM – New evidence continues to show that alternative measures of adiposity than body mass index, such as waist-to-hip ratio, work better for predicting the risk a person with overweight or obesity faces from their excess weight.

A direct comparison of waist-to-hip ratio (WHR), body mass index (BMI), and fat mass index (FMI) in a total of more than 380,000 United Kingdom residents included in the UK Biobank showed that WHR had the strongest and most consistent relationship to all-cause death, compared with the other two measures, indicating that clinicians should pay more attention to adiposity distribution than they do to BMI when prioritizing obesity interventions, Irfan Khan said at the annual meeting of the European Association for the Study of Diabetes.

Moving away from BMI-centric obesity

“This is a timely topic, because guidelines for treating people with obesity have depended so much on BMI. We want to go from a BMI-centric view to a view of obesity that depends more on disease burden,” commented Matthias Blüher, MD, professor of molecular endocrinology and head of the Obesity Outpatient Clinic for Adults at the University of Leipzig (Germany).

MDedge News/Mitchel L. Zoler

For example, the 2016 obesity management guidelines from the American Association of Clinical Endocrinologists and the American College of Endocrinology called for a “complications-centric” approach to assessing and intervening in people with obesity rather than a “BMI-centric” approach.

But Dr. Blüher went a step further in an interview, adding that “waist-to-hip ratio is now outdated,” with adjusted measures of WHR such as waist-to-height ratio “considered a better proxy for all-cause death.” He also gave high marks to the Edmonton Obesity Staging System, which independently added to BMI as well as to a diagnosis of metabolic syndrome for predicting mortality in a sample from the U.S. National Health and Nutrition Examination Survey (NHANES). The Edmonton System also surpassed BMI for disease-severity staging using data from more than 23,000 Canadians with a BMI that denoted obesity.
 

1 standard deviation increase in WHR linked with a 41% increased mortality

The study reported by Mr. Khan used both epidemiologic and Mendelian randomization analyses on data collected from more than 380,000 U.K. residents included in the UK Biobank database to examine the statistical associations between BMI, FMI, and WHR and all-cause death. This showed that while BMI and FMI both had significant, independent associations with all-cause mortality, with hazard ratios of 1.14 for each 1 standard deviation increase in BMI and of 1.17 for each standard deviation increase in FMI, the link was a stronger 1.41 per standard deviation increase in WHR, he said.

Another analysis that divided the entire UK Biobank study cohort into 20 roughly similar subgroups by their BMI showed that WHR had the most consistent association across the BMI spectrum.

Further analyses showed that WHR also strongly and significantly linked with cardiovascular disease death and with other causes of death that were not cardiovascular, cancer-related, or associated with respiratory diseases. And the WHR link to all-cause mortality was strongest in men, and much less robust in women, likely because visceral adiposity is much more common among men, even compared with the postmenopausal women who predominate in the UK Biobank cohort.

One more feature of WHR that makes it an attractive metric is its relative ease of measurement, about as easy as BMI, Mr. Khan said.

The study received no commercial funding, and Mr. Khan had no disclosures. Dr. Blüher has been a consultant to or speaker on behalf of Amgen, AstraZeneca, Bayer, Boehringer Ingelheim, Lilly, Novartis, Novo Nordisk, and Sanofi.
