Eating in response to stress – known as emotional eating – was significantly associated with several markers of long-term cardiovascular damage, based on data from 1,109 individuals.

“We know diet plays a huge role in cardiovascular disease, but we have focused a lot of work on what you eat, not on what makes you eat” – the current study did exactly that, Martha Gulati, MD, who wasn’t involved in the study, said in an interview.

“Emotional eaters consume food to satisfy their brains rather than their stomachs,” study investigator Nicolas Girerd, MD, of the National Institute of Health and Medical Research (INSERM) and a cardiologist at the University Hospital of Nancy (France), wrote in a press release accompanying the study.

Diet plays a role in the development of cardiovascular disease (CVD), but the impact of eating behavior on long-term cardiovascular health remains unclear, wrote Dr. Girerd and colleagues. Previous research has yielded three common psychological dimensions for eating behavior: emotional eating, restrained eating, and external eating.

Both emotional eating and restrained eating have been linked to cardiovascular disease risk, the researchers noted. “Because of previous findings, we hypothesized that [emotional and/or restrained dimensions of eating behavior] are positively associated with cardiovascular damages, as well as with CV risk factors, such as metabolic syndrome,” they wrote.

In a study published in the European Journal of Preventive Cardiology, the researchers reviewed data from 916 adults and 193 adolescents who were participants in the STANISLAS (Suivi Temporaire Annuel Non-Invasif de la Santé des Lorrains Assurés Sociaux), a longitudinal familial cohort in France. Cardiovascular data were collected at four medical visits as part of a full clinical examination between 1993 and 2016, with one visit every 5-10 years. Roughly one-third (31.0%) of the adults were overweight, 7.9% were obese, and 2.7% were underweight. The median age of the adults at the second visit was 44.7 years; the median age of the adolescent group was 15.2 years.

The primary outcome of cardiovascular damage was measured at the fourth visit. Eating behavior was assessed during the second visit using the Dutch Eating Behaviour Questionnaire (DEBQ), and participants were identified as emotional eaters, restrained eaters, or external eaters.

Among the adults, emotional eating was associated with a 38% increased risk of diastolic dysfunction (odds ratio, 1.38; P = .02), over an average follow-up of 13 years, and this association was mediated by stress in 32% of cases. Emotional eating also was positively linked with a higher carotid-femoral pulse-wave velocity (cfPWV-beta), indicative of increased arterial stiffness. However, none of the three dimensions of eating behavior was associated with cardiovascular damage among the adolescents. In addition, none of the eating-behavior dimensions was tied to metabolic syndrome in the adult group (this association was not measured in the adolescents).

Energy intake had no apparent impact on any associations between eating behavior and CVD measures, Dr. Girerd said in the press release. “We might expect that emotional eaters would consume high-calorie foods, which would in turn lead to cardiovascular problems, but this was not the case. One explanation is that we measured average calorie intake and emotional eaters may binge when stressed and then eat less at other times,” and that the resulting “yo-yo” pattern might negatively affect the heart and blood vessels more than stable food intake, he said.

The study findings were limited by several factors, including the observational design that prevented conclusions of causality, the researchers noted. Other limitations included the use of a nonvalidated scale to measure stress, the lack of data on physical activity, and the use of a mainly healthy population in a limited geographic area, which may limit generalizability, they said.

More research is needed in other contexts and larger cohorts, but the results were strengthened by the large study population and the complete data on eating behaviors and detailed health information, they wrote. The results support previous studies and suggest that patients with emotional eating behavior could benefit from emotion regulation skills training, including cognitive, behavioral, psychological, and interpersonal therapies used in other areas, and from pharmacological treatments, the researchers concluded.

The current study offers a unique and important perspective on the relationship between diet and cardiovascular disease, Dr. Gulati, director of preventive cardiology at the Smidt Heart Institute at Cedars-Sinai Medical Center, Los Angeles, told this news organization.

“Examining eating behavior and its relationship with cardiovascular effects in healthy individuals in this prospective way is quite interesting,” said Dr. Gulati, who was not involved in the study.

The researchers examined healthy people at baseline, inquired about their eating habits, and found that emotional eaters “have evidence of cardiovascular changes when compared with the other groups of eaters, after controlling for other risk factors that are associated with cardiovascular disease when following them for 13 years,” said Dr. Gulati, who was recently named Anita Dann Friedman Endowed Chair in Women’s Cardiovascular Medicine and Research at Cedars-Sinai. “This same finding wasn’t seen in adolescents, but this is probably because they are younger, and the effects aren’t seen. That is reassuring, because it means that the more we address eating behaviors, the more likely we are to reduce their effects to the heart,” she noted.

“This study is important because usually, as cardiologists or anyone in medicine, how we assess diet is by assessment of what food people eat; we don’t usually ask about what triggers them to eat,” Dr. Gulati said. “Eating behaviors based on their triggers ultimately affect food choice and food quantity, and help us understand weight changes during a lifetime,” she said.

“I think we don’t have the data to know that an eating behavior would be able to affect cardiac function,” said Dr. Gulati, “but I think we all might hypothesize that emotional eating may be associated with abnormal diastolic function simply through eating high-density food and weight gain.”

The current study did not show a relationship between eating behavior and metabolic syndrome, in contrast with prior studies, Dr. Gulati noted. However, “the authors report that the association between eating behaviors and diastolic dysfunction was mediated through the stress level,” Dr. Gulati said. “It is important to note that this European population was healthy at baseline, and also relatively healthy 13 years later, which makes these findings even more profound.”

Dr. Gulati said that she agrees with the study authors on the need to assess diet and eating behaviors when assessing cardiovascular risk in patient. “Diet assessment as part of prevention is central, but we should ask not only ‘what do you eat,’ but also ‘what makes you eat,’ ” she said.

More research is needed in other populations, Dr. Gulati added. The current study population was healthy at baseline and follow-up. Studies are needed in cohorts in the United States and in the developing world to see how the results might differ; as well as in rural America or in “food deserts” where food choices are limited.

Another research topic is the interplay between eating behaviors and social determinants of health, in terms of their effect on cardiovascular function, Dr. Gulati said, “and it will be valuable to follow this cohort further to see how these eating behaviors and these intermediate measures translate into cardiovascular outcomes.” Future studies should also examine whether the changes in cardiac function are reversible by interventions to modify eating behavior, particularly emotional eating, she said.

Supporters of the study included the Regional University Hospital Center of Nancy, the French Ministry of Solidarity and Health, and a public grant overseen by the French National Research Agency. The researchers had no financial conflicts to disclose.

A new study that quantifies the harm to the liver of eating fast food might motivate people to eat less of it – especially those with obesity or diabetes.

The study finds that getting one-fifth or more of total daily calories from fast food can increase the risk of nonalcoholic fatty liver disease, which can lead to cirrhosis and its complications, including liver failure and liver cancer.

Although the magnitude of association was modest among the general population, “striking” elevations in steatosis were evident among persons with obesity and diabetes who consumed fast food, in comparison with their counterparts who did not have obesity and diabetes, the researchers reported.

“My hope is that this study encourages people to seek out more nutritious, healthy food options and provides information that clinicians can use to counsel their patients, particularly those with underlying metabolic risk factors, of the importance of avoiding foods that are high in fat, carbohydrates, and processed sugars,” lead investigator Ani Kardashian, MD, hepatologist with the University of Southern California, Los Angeles, said in an interview.

“At a policy level, public health efforts are needed to improve access to affordable, healthy, and nutritious food options across the U.S. This is especially important as more people have turned to fast foods during the pandemic and as the price of food as risen dramatically over the past year due to food inflation,” Dr. Kardashian added.

The study was published online in Clinical Gastroenterology and Hepatology.
 

More fast food, greater steatosis

The findings are based on data from 3,954 adults who participated in the National Health and Nutrition Examination Survey (NHANES) of 2017-2018 and who underwent vibration-controlled transient elastography. Of these participants, data regarding 1- or 2-day dietary recall were available.

Steatosis, the primary outcome, was measured via controlled attenuation parameter (CAP). Two validated cutoffs were utilized (CAP ≥ 263 dB/m and CAP ≥ 285 dB/m).

Of those surveyed, 52% consumed any fast food, and 29% derived 20% or more of their daily calories from fast food.

Fast-food intake of 20% or more of daily calories was significantly associated with greater steatosis after multivariable adjustment, both as a continuous measure (4.6 dB/m higher CAP score) and with respect to the CAP ≥ 263 dB/m cutoff (odds ratio [OR], 1.45).

“The negative effects are particularly severe in people who already have diabetes and obesity,” Dr. Kardashian told this news organization.

For example, with diabetes and fast-food intake of 20% or more of daily calories, the ORs of meeting the CAP ≥ 263 dB/m cutoff and the CAP ≥ 285 dB/m cutoff were 2.3 and 2.48, respectively.

The researchers said their findings are particularly “alarming,” given the overall increase in fast-food consumption over the past 50 years in the United States, regardless of socioeconomic status.

The finding that fast food has more deleterious impact on those with obesity and diabetes “emphasizes that it is not just one insult but multiple factors that contribute to overall health,” said Nancy Reau, MD, section chief of hepatology at Rush University Medical Center in Chicago.

“This is actually great news, because diet is modifiable, vs. your genetics, which you currently can’t change. This doesn’t mean if you’re lean you can eat whatever you want, but if you are overweight, being careful with your diet does have impact, even if it doesn’t lead to substantial weight changes,” said Dr. Reau, who is not affiliated with the study.

For people who have limited options and need to eat fast food, “there are healthy choices at most restaurants; you just need to be smart about reading labels, watching calories, and ordering the healthier options,” Dr. Reau said in an interview.

Fast food and fatty liver go “hand in hand,” Lisa Ganjhu, DO, gastroenterologist and hepatologist at NYU Langone Health in New York, told this news organization.

“I counsel and coach my patients on healthy diet and exercise, and I’ve been pretty successful,” said Dr. Ganjhu, who was not involved with the study.

“If my patient is eating at McDonald’s a lot, I basically walk through the menu with them and help them find something healthy. When patients see the benefits of cutting out fat and reducing carbohydrates, they are more apt to continue,” Dr. Ganjhu said.

The study was funded by the University of Southern California. Dr. Kardashian, Dr. Reau, and Dr. Ganjhu have disclosed no relevant financial relationships.

“I counsel and coach my patients on healthy diet and exercise, and I’ve been pretty successful,” said Dr. Ganjhu, who was not involved with the study.

“If my patient is eating at McDonald’s a lot, I basically walk through the menu with them and help them find something healthy. When patients see the benefits of cutting out fat and reducing carbohydrates, they are more apt to continue,” Dr. Ganjhu said.

The study was funded by the University of Southern California. Dr. Kardashian, Dr. Reau, and Dr. Ganjhu have disclosed no relevant financial relationships.

People who are overweight or have obesity appear to show a blunted response to vitamin D supplementation compared with normal-weight individuals in a new analysis of a randomized trial.

“There seems to be something different happening with vitamin D metabolism at higher body weights, and this study may help explain diminished outcomes of supplementation for individuals with an elevated body mass index (BMI),” said first author Deirdre K. Tobias, ScD, an associate epidemiologist at Brigham and Women’s Hospital’s division of preventive medicine in Boston. She made the comments in a press statement issued with the study, published online in JAMA Network Open.

The findings are from a post hoc analysis of the large-scale Vitamin D and Omega-3 Trial (VITAL), which overall, showed no benefits among those randomized to 5 years of vitamin D supplementation (2,000 IU/day) versus placebo in terms of the primary endpoints of cancer or major cardiovascular disease outcomes.

However, prespecified secondary analyses according to body weight showed that those of normal weight (body mass index < 25.0 kg/m²) did have significant benefits from supplementation versus placebo in terms of cancer incidence (24% lower), cancer mortality (42% lower), and autoimmune disease (22% lower), while no corresponding benefits were observed among those who were overweight or had obesity.

The new analysis adds important context to the trial’s overall findings, noted Katherine N. Bachmann, MD, in an accompanying editorial.

“Thanks to its very large sample size and detailed biomarker analyses, the current study is able to provide novel evidence that responses to vitamin D supplementation may be attenuated in individuals with overweight and obesity, and that this may contribute to the differential outcomes by BMI noted in the original VITAL,” she wrote.

“Further studies are warranted to determine the optimal dose or circulating vitamin D level for individuals with obesity for nonskeletal health-related outcomes,” added Dr. Bachmann, division of diabetes, endocrinology, and metabolism at Vanderbilt University Medical Center, Nashville, Tenn.
 

New analysis examined vitamin D and biomarkers at baseline and 2 years

To take a closer look at the specific changes in vitamin D serum and biomarker levels between the different body-weight groups, Dr. Tobias and colleagues evaluated data from 16,515 participants in the trial (of the 25,000 originally included in VITAL) and looked at changes in key vitamin D serum levels and biomarkers at baseline and follow-up.

Consistent with common observations of lower vitamin D levels with obesity, participants in the higher BMI categories had incrementally lower mean levels of serum total 25-hydroxyvitamin D (25-OHD) prior to randomization, with levels ranging from 32.3 ng/mL for normal weight individuals to 28.0 ng/mL for those with obesity class II (P < .001 for a linear trend).

Baseline levels of other vitamin D biomarkers were also lower with higher BMI, including total 25-OHD 3, free vitamin D (FVD), and bioavailable vitamin D (BioD).

Among 2,742 participants with repeated blood collections at year 2, significant mean increases were observed overall at the end of the study period in serum 25-OHD levels (11.9 ng/mL) among those randomized to vitamin D supplementation, compared with little change in the placebo group (–0.7 ng/mL).

There were also significant increases, overall, in mean total 25-OHD, 25-OHD3, FVD, and BioD levels at 2 years among those receiving supplementation, with little or no change in the placebo group.

When stratified by BMI level, however, the magnitude of increase was lower among those with higher baseline BMI (all treatment effect interactions P < .001). For instance, the mean increases in total 25-OHD level at 2 years for supplementation versus placebo were 13.5 ng/mL for those with a BMI less than 25.0 versus only 10.0 ng/mL for those with a BMI of at least 35.0.

Importantly, even after controlling for baseline vitamin D status of sufficiency or insufficiency, BMI was still significantly associated with changes seen with supplementation.

“It was surprising that, even in the context of low vitamin D levels, those with higher BMI still had a blunted response to supplementation, suggesting the interaction between supplementation and BMI with health outcomes is not simply due to higher prevalence of deficiency,” Dr. Tobias said in an interview. “It really does seem that, even with insufficient or low levels at baseline, those with higher BMI are not able to catch up to sufficient levels as well as those with normal BMI.”
 

Mechanisms?

Among leading theories as to why higher BMI would be associated with lower serum vitamin D levels and a lower response to supplementation is that because vitamin D is a fat-soluble vitamin, the increased adiposity and fat storage capacity with higher BMI results in greater removal of the vitamin from circulation.

“Our results are largely consistent with this hypothesis,” the authors noted.

They added that weight-loss studies, including those involving bariatric surgery, have further shown greater increases in serum 25-OHD or circulating vitamin D levels after weight loss compared with baseline.

Other theories suggest that obesity-induced hepatic dysfunction can contribute to impaired vitamin D metabolism.

Without a clear understanding of the exact mechanisms, the potential for addressing the lower vitamin D levels with, for instance, higher doses of supplementation among those with obesity, also remains unclear, Dr. Tobias noted.

“I think once there’s more clarity on what the mechanism is, then it would make sense to consider what doses could be necessary to achieve the internal levels desired,” she said.

The VITAL study received funding from a grant from the National Center for Complementary and Integrative Health and other sources.

Gestational diabetes is a significant health problem worldwide that is associated with immediate and lifelong consequences for the affected woman and her infant. Gestational diabetes increases the risk for pregnancy-related complications, such as induced labor, cesarean delivery, and preeclampsia. There is also an increased risk for neonatal complications, including large-for-gestational-age birth weight, shoulder dystocia, birth injuries, lung disease, jaundice, and hypoglycemia. Regardless of birth weight, neonates born to mothers with gestational diabetes have greater adiposity than do neonates born to mothers without obesity and with normal glucose tolerance, and they have a predilection toward obesity and obesity-related metabolic disorders, including T2D in childhood and adulthood. Similarly, women who develop gestational diabetes have an increased lifetime risk for T2D as well as an increased risk for cardiovascular disease even if they do not progress to T2D.

According to the International Diabetes Federation, 1 in 6 pregnancies is affected by gestational diabetes. Risk factors include higher age and BMI, previous history of gestational diabetes, a family history of T2D, and polycystic ovarian syndrome. Patients may have few, if any, symptoms of gestational diabetes, or they may mistake their symptoms for the normal side effects of pregnancy. Potential symptoms include blurred vision, tingling or numbness in the hands and/or feet, excessive thirst, frequent urination, sores that heal slowly, and excessive fatigue. 

The American Diabetes Association (ADA) states that the treatment of gestational diabetes should include medical nutrition therapy, physical activity, and weight management, depending on pregestational weight. Glucose monitoring is essential: Patients should aim for fasting glucose < 95 mg/dL (5.3 mmol/L) and either 1-hour postprandial glucose < 140 mg/dL (7.8 mmol/L) or 2-hour postprandial glucose < 120 mg/dL (6.7 mmol/L). According to the ADA, insulin should be added to lifestyle modifications if needed to achieve glycemic targets. Metformin and glyburide are not recommended as first-line agents because both cross the placenta to the fetus. Long-term safety data are not available for the use of other oral and noninsulin injectable glucose-lowering medications during pregnancy.

Bariatric surgery for severe obesity does not appear to raise the risk of esophageal and gastric cancer, a new study shows.

In fact, an analysis of close to 1 million French adults suggests that the weight-loss surgery may offer some protection against these cancers.

The study results present a “clinical paradox,” according to authors of a commentary published this week along with the study in JAMA Surgery. A procedure known to increase the risk of gastroesophageal reflux disease (GERD), and potentially adenocarcinoma of the distal esophagus and gastroesophageal junction, may help shield patients from esophagogastric cancer.

The study marks “an important step toward improving the understanding of potential lifetime risks of bariatric surgery and overall major health benefits of surgically induced weight loss,” commentary authors Piotr Gorecki, MD, and Michael Zenilman, MD, with Weill Cornell Medicine in New York, write.

Recent data indicate that excess body weight is associated with nearly 8% of cancer cases and 6.5% of cancer deaths. Studies also show that bariatric surgery can reduce the risk of some cancers, but whether this extends to esophageal and gastric cancer remains unclear.

To investigate, the researchers used French national data to compare the incidence of esophageal and gastric cancer in 303,709 mostly female patients with obesity who underwent bariatric surgery and a matched group of 605,140 patients with obesity who did not undergo the surgery.

The mean age of the cohort was about 40 years. The mean period of follow-up was 6 years for the surgery group and 5.6 years for the control arm. A total of 337 patients underwent esophagogastric cancer – 83 in the surgical group and 254 in the control group. Gastric cancer was about two times more common than esophageal cancer (225 vs. 112 patients).

The incidence rate of esophagogastric cancer was higher in the control group than in the surgery group – 6.9 vs. 4.9 cases per 100,000 population per year, for an incidence rate ratio of 1.42 (P = .005).

Bariatric surgery was associated with a significant 24% lower risk of esophagogastric cancer (hazard ratio, 0.76; P = .03) and a 40% lower risk of overall in-hospital mortality, defined as “any death occurring during a hospital stay regardless of the cause” (HR, 0.60; P < .001).

The authors also found no significant difference in cancer outcomes and type of bariatric procedure, which included sleeve gastrectomy, gastric bypass, and adjustable gastric banding.

They note that key study limitations include the retrospective design, limited follow-up period, and lack of histologic data on the specific cancers. In addition, the study population was relatively young, whereas esophageal cancer is more common in older people.

But overall, the findings suggest that bariatric surgery can be performed to treat severe obesity without increasing the risk of esophageal and gastric cancer, the authors conclude.

“It seems that the balance between protective factors (weight loss, metabolic effects, and eradication of H. pylori infection) and risk factors (GERD and bile reflux) for cancer after bariatric surgery is in favor of protective factors,” the authors, led by Andrea Lazzati, MD, PhD, of Centre Hospitalier Intercommunal de Créteil, France, explain.

Although the potential protective mechanisms remain unclear, in their commentary, Dr. Gorecki and Dr. Zenilman suggest that a reduction in chronic inflammation and immunosuppression following bariatric surgery could help explain the results.

Although the study provides “reassurance of the protective clinical benefits of weight loss surgery,” more large-scale studies are needed to “better identify, elucidate, and address the pathophysiological processes of bariatric procedure,” Dr. Gorecki and Dr. Zenilman conclude.

No specific funding for the study was reported. Dr. Lazzati has received personal fees from Johnson & Johnson, Medtronic, and Gore. Dr. Zenilman has received personal fees from Academic Medical Professionals Insurance and Mohamed & Obaid Almulla Group.

Bariatric surgery was associated with a significant 24% lower risk of esophagogastric cancer (hazard ratio, 0.76; P = .03) and a 40% lower risk of overall in-hospital mortality, defined as “any death occurring during a hospital stay regardless of the cause” (HR, 0.60; P < .001).

The authors also found no significant difference in cancer outcomes and type of bariatric procedure, which included sleeve gastrectomy, gastric bypass, and adjustable gastric banding.

They note that key study limitations include the retrospective design, limited follow-up period, and lack of histologic data on the specific cancers. In addition, the study population was relatively young, whereas esophageal cancer is more common in older people.

But overall, the findings suggest that bariatric surgery can be performed to treat severe obesity without increasing the risk of esophageal and gastric cancer, the authors conclude.

“It seems that the balance between protective factors (weight loss, metabolic effects, and eradication of H. pylori infection) and risk factors (GERD and bile reflux) for cancer after bariatric surgery is in favor of protective factors,” the authors, led by Andrea Lazzati, MD, PhD, of Centre Hospitalier Intercommunal de Créteil, France, explain.

Although the potential protective mechanisms remain unclear, in their commentary, Dr. Gorecki and Dr. Zenilman suggest that a reduction in chronic inflammation and immunosuppression following bariatric surgery could help explain the results.

Although the study provides “reassurance of the protective clinical benefits of weight loss surgery,” more large-scale studies are needed to “better identify, elucidate, and address the pathophysiological processes of bariatric procedure,” Dr. Gorecki and Dr. Zenilman conclude.

No specific funding for the study was reported. Dr. Lazzati has received personal fees from Johnson & Johnson, Medtronic, and Gore. Dr. Zenilman has received personal fees from Academic Medical Professionals Insurance and Mohamed & Obaid Almulla Group.

Peripheral airway response to methacholine was similar among obese adults with and without asthma, although forced expiratory volume was lower for those with asthma, based on data from 53 individuals.

Obesity remains a risk factor for asthma, and obese individuals with asthma tend to have worse control and more severe disease, compared with nonobese asthma patients, wrote Anne E. Dixon, BM, BCh, of the University of Vermont, Burlington, and colleagues.

Previous studies have shown that airway reactivity can occur in obese individuals without airway inflammation, but studies characterizing obese asthma based on lung function are lacking, they said. “Combining spirometry and oscillometry might reveal abnormalities in lung mechanics particularly pertinent to people with obesity and asthma,” the researchers noted.

In a cross-sectional study published in the journal CHEST, the researchers reviewed data from 31 obese adults with asthma and 22 obese adults without asthma. The participants were aged 18 years and older, with forced expiratory volume (FEV₁) of at least 60% of predicted. All had class III obesity, with an average BMI of 47.2 kg/m² for those with asthma and 46.7 kg/m² for nonasthma controls. Demographic characteristics were similar between the groups.

Airway reactivity was defined as a 20% decrease in FEV₁ and/or a 50% change in resistance or reactance at 5 Hz (R5 and X5), at a concentration of 16 mg/mL or less of methacholine. Patients were assessed using spirometry and oscillometry.

Overall, most obese individuals with and without asthma showed significant changes in peripheral airway resistance. For those with asthma, the resistance at 5 Hz, measured by oscillometry, increased by 52% in response to the PC20 methacholine challenge, with an area under the reactance curve (AX) of 361%. For controls without asthma, the resistance at 5 Hz increased by 45%, with an AX of 268% in response to 16 mg/mL of methacholine.

This finding suggests that obesity predisposes individuals to peripheral airway reactivity regardless of asthma status, the researchers wrote in their discussion.

The researchers also identified two distinct groups of asthma patients categorized by respiratory system impedance based on more concordant vs. discordant bronchoconstriction in the central and peripheral airways. The baseline AX for these two groups was 11.8 and 46.7, respectively, with interquartile ranges of 9.9-23.4 and 23.2-53.7, respectively.

The discordant group included only women, and these patients reported significantly more gastroesophageal reflux, increased chest tightness, and more wheezing and asthma exacerbations than the concordant group, which may be related to air trapping, shown on previous studies of obese individuals with asthma, the researchers wrote.

The findings were limited by several factors, including the measurement of airway impedance only at the peak methacholine dose and the measurement of oscillometry after spirometry, the researchers noted. Other limitations included the relatively small study population at a single center, and the focus on obese individuals only.

More research is needed in larger and more diverse patient populations, but the results support the characterization of a subgroup of obese asthma patients with significant peripheral airway dysfunction, the researchers wrote.

“Oscillometry testing can reveal a physiologic phenotype of asthma in obesity that may be related to worse symptoms and more severe disease, and also reveal subclinical abnormalities in people with obesity, but without clinically diagnosed lung disease,” they concluded.

The study was supported in part by the National Institutes of Health. The researchers declared no financial conflicts.

Primary care providers should treat obesity in children and adolescents aggressively including with medication and weight-loss surgery rather than rely on “watchful waiting” and hope the problem solves itself. That’s the upshot of new guidelines from the American Academy of Pediatrics.

The authors of the guidelines also encourage primary care doctors to collaborate with other medical professionals to treat the comorbidities often linked to obesity, rather than take on the entire challenge themselves.

“It’s impossible to treat obesity within the four walls of the clinic. That’s one thing I have learned,” Ihuoma Eneli, MD, associate director of the AAP Institute for Healthy Childhood Weight, told this news organization. For example, a primary care doctor could partner with a gastroenterologist when treating a child who has nonalcoholic fatty liver disease, added Dr. Eneli, a professor of pediatrics at the Ohio State University, Columbus, who helped write the recommendations.

The new document updates 2007 recommendations from AAP about treating children and adolescents who are overweight or obese. The earlier statement focused on behavioral modification and healthy eating behaviors and paid less attention to weight-lowering medications or bariatric surgery for young people. That document did not offer specific advice to health care providers about how to address childhood overweight or obesity.

The 2023 guidelines recommend that pediatricians offer anyone aged 12 years and older with obesity – defined as a body mass index (BMI) at the 95th percentile or higher – the option of receiving weight-loss medications in addition to ongoing support for lifestyle modifications, such as exercising more and eating healthier foods.

The same approach holds for bariatric surgery once children reach age 13, and AAP stressed that no physician should ever stigmatize children or imply that they are to blame for their weight.

AAP did not receive any industry funding to develop the guidelines.

As children reach the threshold BMI levels, physicians should conduct complete physicals and order blood tests to get a fuller picture of the patients’ health.

These are the first guidelines from AAP aimed at giving pediatricians and other primary care providers concrete guidance for managing overweight and obesity in younger patients.

“Obesity is a complex, chronic disease, and that’s a frame shift here,” said Sandra S. Hassink, MD, leader of the guideline group and director of the AAP Institute for Healthy Childhood Weight.

Dr. Hassink compared obesity to asthma, another chronic disease that merits prompt attention and ongoing treatment. A physician would never let a child with asthma go untreated until their breathing problems are so severe that they turn blue, Dr. Hassink said; similarly, physicians should treat obesity in young people promptly and over time.

While some aspects of treating overweight and obesity are the same for children and adults, Dr. Hassink noted distinct differences. “Every child is embedded in a family and extended support structure,” Dr. Hassink said, which means that any obesity management technique needs the buy-in and support of the child’s family too.

AAP’s new advice reflects current understanding that excess weight or obesity in children is a result of biological and social factors, such as living in a food desert or experiencing the effects of structural racism.

The guidelines synthesize the results of hundreds of studies about the best way to treat excess weight in young people. If multiple studies were of high quality and all reached similar conclusions, they received an “A.” Less robust but still informative studies rated a “B.” In aggregate, the guideline about weight-lowering medication is based on “B” evidence that could shift with further research.

The authors recommend that clinicians calculate a child’s BMI beginning at age 2 years, with particular attention to those at the 85th percentile or higher for their age and sex (which would be defined as overweight), at the 95th percentile or higher (obesity), or at the 120th percentile and higher (severe obesity). Clinicians also should monitor blood pressure and cholesterol in their patients with overweight or obesity, particularly once they reach age 10.

Starting at age 6, providers should interview patients and their families about what would motivate them to lose weight, then tailor interventions to those factors rather than just make a blanket declaration that weight loss is necessary. This step should be coupled with intensive support – ideally, at least 26 hours of face-to-face support over the course of a year, although more is better – about effective exercise and dietary habits that result in weight loss.

The intensive support model should remain in place throughout childhood and adolescence and should be coupled with referrals for weight-loss medications or bariatric surgeries as needed once children reach age 12 or 13. Those age cutoffs are based on current evidence as to when weight-loss medications or surgery becomes effective, Dr. Hassink said, and could be shifted to lower ages if that’s what new evidence shows.

“Intensive health behavioral and lifestyle treatment is the base of all other treatment extensions,” Dr. Eneli said.

Young patients who needed weight-lowering medication used to have fewer options, according to Aaron S. Kelly, PhD, the Minnesota American Legion and Auxiliary Chair in Children’s Health at the University of Minnesota, Minneapolis.

.No longer.

Dr. Kelly was not involved in drafting the guidelines but was the lead investigator for trials of liraglutide (Saxenda), which in 2020 received U.S. Food and Drug Administration approval for treating obesity in adolescents. In 2022, the agency approved phentermine and topiramate extended-release capsules (Qsymia) for long-term weight management for patients aged 12 years and older, along with a once-weekly injection of semaglutide (Wegovy) patients in this age group. There are no weight-lowering medications for children younger than 12, Dr. Kelly said.

“Obesity is not a lifestyle problem. A lot of it is driven by the underlying biology,” Dr. Kelly said. “Really, what these medicines do is make it easier for people to make the right lifestyle choices by pushing back against the biology.”

For example, a drug can make people feel full for longer or disrupt chemical pathways that result in craving certain foods. Dr. Kelly emphasized that these drugs do not give license for people to eat as much as they want.

As for bariatric surgery, the new guidelines adhere closely to those in a 2019 AAP statement that bariatric surgery is safe and effective in pediatric settings. This is gratifying to Kirk W. Reichard, MD, MBA, a lead author of the 2019 article and director of the bariatric surgery program at Nemours Children’s Health.

Even if the information isn’t new as of 2023, Dr. Reichard said, AAP’s imprimatur could cause some eligible families to consider bariatric surgery when they may not have done so before.

Dr. Eneli, Dr. Hassink, and Dr. Reichard reported no relevant financial conflicts of interest. Dr. Kelly has relationships with Boehringer Ingelheim, Eli Lilly, Novo Nordisk, and Vivus.

Starting colorectal cancer screening earlier than age 50 appears to be cost-effective for both men and women across all body mass index (BMI) measures, according to a study published in Clinical Gastroenterology and Hepatology.

In particular, colonoscopy is cost-effective at age 45 for all BMI strata and at age 40 in obese men. In addition, fecal immunochemical testing (FIT) is highly cost-effective at ages 40 or 45 for all BMI values, wrote Aaron Yeoh, MD, a gastroenterologist at the Stanford (Calif.) University, and colleagues.

Increased body fatness, defined as a high BMI, has increased sharply in recent decades and has been associated with a higher risk of colorectal cancer (CRC). Given the rising incidence of CRC in younger people, the American Cancer Society and U.S. Preventive Services Task Force now endorse screening at age 45. In previous analyses, Dr. Yeoh and colleagues suggested that the policy is likely to be cost-effective, but they didn’t explore the potential differences by BMI.

“Our results suggest that 45 years of age is a reasonable screening initiation age for women and men with BMI ranging from normal through all classes of obesity,” the authors wrote. “Before changing screening policy, supportive data from clinical studies would be needed. Our approach can be applied to future efforts aiming to risk-stratify CRC screening based on multiple clinical factors or biomarkers.”

The research team examined the potential effectiveness and cost-effectiveness of screening tailored to BMI starting as early as age 40 and ending at age 75 in 10 separate cohorts of men and women of normal weight (18.5 to <25 kg/m²), overweight (25 to <30 kg/m²), and three strata of obesity – obese I (30 to <35 kg/m²), obese II (35 to <40 kg/m²), and obese III (>40 kg/m²).

For each cohort, the researchers estimated incremental costs per quality-adjusted life year (QALY) gained by initiating screening at age 40 versus age 45 versus age 50, or by shortening colonoscopy intervals. They modeled screening colonoscopy every 10 years (Colo10) or every 5 years (Colo5), or annual FIT, offered from ages 40, 45, or 50 through age 75 with 100% adherence, with postpolypectomy surveillance through age 80.

For model inputs, the research team favored high-quality data from meta-analyses or large prospective trials. Screening, treatment, and complication costs were set at 2018 Centers for Medicare & Medicaid Services rates for ages 65 and older and modified to reflect commercial costs at ages 65 and younger. The authors assumed use of moderate sedation, and sensitivity analyses addressed possible increased costs and complications of colonoscopy under propofol.

Overall, without screening, sex-specific total CRC deaths were similar for people with overweight or obesity I-III and slightly higher than for people with normal BMI. For both men and women across all BMI strata, Colo10 or FIT starting at age 50 substantially decreased CRC incidence and mortality versus no screening, and the magnitude of the clinical impact was comparable across BMI.

For both sexes across BMI, Colo10 or FIT starting at age 50 was highly cost-effective. The cost per QALY gained for Colo10 compared with no screening became more favorable as BMI increased from normal to obesity III. FIT was cost-saving compared with no screening for all cohorts and was cost-saving or highly cost-effective compared with Colo10 within each cohort.

Initiating Colo10 at age 45 showed incremental decreases in CRC incidence and mortality, which were modest compared with the gains of Colo10 at age 50 versus no screening. However, the incremental gains were achieved at acceptable incremental costs ranging from $64,500 to $85,900 per QALY gained in women and from $33,400 to $64,200 per QALY gained in men.

Initiating Colo10 at age 40 in women and men in the lowest three BMI strata was associated with high incremental costs per QALY gained. In contrast, Colo10 initiation at age 40 cost $80,400 per QALY gained in men with obesity III and $93,300 per QALY gained in men with obesity II.

FIT starting at ages 40 or 45 yielded progressively greater decreases in CRC incidence and mortality for both men and women across BMI strata, and it was highly cost-effective versus starting at later ages. Compared with Colo10, at every screening initiation age, FIT was cost-saving or preferred based on very high incremental costs per QALY, and FIT required substantially fewer colonoscopies per person.

Intensifying screening by shortening the colonoscopy interval to Colo5 was never preferred over shifting Colo10 to earlier screening initiation ages. In all cohorts, Colo5 was either less effective and more costly than Colo10 at a younger age, or when it was more effective, the cost per QALY gained was substantially higher than $100,000 per QALY gained.

Additional studies are needed to understand obesity-specific colonoscopy risks and costs, the authors wrote. In addition, obesity is only one of several factors that should be considered when tailoring CRC screening to the level of CRC risk, they wrote.

“As the search for a multifactor prediction tool that is ready for clinical application continues, we face the question of how to approach single CRC risk factors such as obesity,” they wrote. “While screening guidelines based on BMI can be envisioned if supportive clinical data accumulate, clinical implementation must overcome operational challenges.”

The study funding was not disclosed. One author reported advisory and consultant roles for several medical companies, and the remaining authors disclosed no conflicts.

Starting colorectal cancer screening earlier than age 50 appears to be cost-effective for both men and women across all body mass index (BMI) measures, according to a study published in Clinical Gastroenterology and Hepatology.

In particular, colonoscopy is cost-effective at age 45 for all BMI strata and at age 40 in obese men. In addition, fecal immunochemical testing (FIT) is highly cost-effective at ages 40 or 45 for all BMI values, wrote Aaron Yeoh, MD, a gastroenterologist at the Stanford (Calif.) University, and colleagues.

Increased body fatness, defined as a high BMI, has increased sharply in recent decades and has been associated with a higher risk of colorectal cancer (CRC). Given the rising incidence of CRC in younger people, the American Cancer Society and U.S. Preventive Services Task Force now endorse screening at age 45. In previous analyses, Dr. Yeoh and colleagues suggested that the policy is likely to be cost-effective, but they didn’t explore the potential differences by BMI.

“Our results suggest that 45 years of age is a reasonable screening initiation age for women and men with BMI ranging from normal through all classes of obesity,” the authors wrote. “Before changing screening policy, supportive data from clinical studies would be needed. Our approach can be applied to future efforts aiming to risk-stratify CRC screening based on multiple clinical factors or biomarkers.”

It’s officially 2023, and if history repeats, millions of Americans are likely vowing that this year will be one when they drop those unwanted pounds for good. After all, weight loss usually lands one of the top spots on New Year’s resolution surveys. 

And just in time, there’s guidance to pick the best plan, as U.S. News & World Report’s annual rankings of the best diet plans were released on Jan. 3.

Once again, the Mediterranean diet, which emphasizes fruits, vegetables, olive oil, and fish, got the top spot, as best diet overall. It’s the sixth consecutive year for that win. But many other diets got top marks as well.

In 2023, U.S. News, with the help of more than 30 nutritionists, doctors, and epidemiologists, ranked 24 diets in several categories to help people find a plan that meets their goals, whether it’s finding the best weight loss diet, easiest one to follow, or plans for other goals, such as managing diabetes or heart disease. Two new categories were added: Best Diets for Bone & Joint Health and Best Family-Friendly Diets. 

In previous years, the publication ranked 40 diets. Even if a diet is no longer ranked, its profile with detailed information remains on the site. 

“Each year we ask ourselves what we can do better or differently next time,” said Gretel Schueller, managing editor of health for U.S. News. When the publication got feedback from their experts this year, they had requests to consider sustainability of diets and whether they meet a busy family’s needs, in addition to considering many other factors. 

This year’s report ranks plans in 11 categories.

The winners and the categories:
 

Best diets overall

After the Mediterranean diet, two others tied for second place:

• DASH (Dietary Approaches to Stop Hypertension) diet, which fights high blood pressure and emphasizes fruits, vegetables, whole grains, lean protein, and low-fat dairy.
• Flexitarian diet, which focuses on fruits, vegetables, and other healthy foods but also allows occasional meat.

Best weight-loss diets

WW, formerly known as Weight Watchers, got first place. The plan emphasizes not only weight loss but healthier eating and regular activity. The Points program, which assigns specific points to foods, with a daily Points budget, is more personalized than in the past.

• DASH got second place.
• Mayo Clinic Diet and TLC diet tied for third place. The Mayo Clinic Diet focuses on fruits, vegetables, and whole grains. It helps people improve their eating habits. The TLC diet (Therapeutic Lifestyle Changes) focuses on vegetables, fruit, lean protein, and reducing cholesterol levels. 

Best fast weight-loss diets

The keto diet got first place. It’s a high-fat, low-carb diet that aims to achieve weight loss through fat burning. Four others tied for second place:

• Atkins, a diet created by the cardiologist Robert Atkins, which begins with very few carbs and then recommends progressively eating more until the weight loss goal is achieved 
• Nutrisystem, a commercial program that includes prepackaged meals and focuses on high-protein, lower-glycemic foods to stabilize blood sugar levels
• Optavia, a plan focused on low-carb, low-calorie foods and including fortified meal replacements 
• SlimFast Diet, a plan of shakes, smoothies, and meal bars to replace two of three meals a day

Best diets for healthy eating

• Mediterranean
• DASH
• Flexitarian

Best heart-healthy diets

• DASH
• Mediterranean
• Flexitarian and Ornish tied for third. The Ornish Diet focuses on plant-based and whole foods and limiting animal products. It recommends daily exercise and stress reduction.

Best diets for diabetes

• DASH
• Mediterranean
• Flexitarian

Best diets for bone and joint health

DASH and Mediterranean are in a first-place tie, followed by the flexitarian diet.

Best family-friendly diets

This category has a three-way tie: the flexitarian, Mediterranean, and TLC diets. 

Best plant-based diets

Mediterranean was first, then flexitarian and the MIND diet. The MIND diet combines the DASH and Mediterranean diets and focuses on “brain-healthy” foods.

Easiest diets to follow

Flexitarian and TLC tied for first, followed by a tie between DASH and Mediterranean.

Best diet programs (formerly called commercial plans)

• WW
• There was a tie for second place between Jenny Craig and Noom, the latter of which focuses on low-calorie foods, with personalized calorie ranges and coaching to help meet goals.

Methodology

A variety of factors were considered, such as whether a diet includes all food groups, how easy it is to follow, whether it can be customized to meet cultural and personal preferences, and if it has a realistic timeline for weight loss. 

Response from diet plans

Representatives from two plans that received mixed reviews in the rankings responded.

Jenny Craig was ranked second for best diet program but much lower for family friendly, landing at 22nd place of 24. 

“Our program is designed to address the needs of the individual through personalized experiences,” Jenny Craig CEO Mandy Dowson said. “We have many families that participate in our program together but are still evaluated separately to determine appropriate individual goals.”

Its high ranking for best diet program reflects feedback from satisfied members, she said. Among advances will be the new Jenny Fresh program, a line of entrées prepared fresh and delivered to customers’ doors.

Atkins got second place for best fast weight loss but ranked near the bottom for best overall, best weight loss, diabetes, healthy eating, and heart health. In response, Colette Heimowitz, vice president of nutrition and education for Simply Good Foods, which makes Atkins’s food products, said that low-carb eating approaches are a viable option for anyone today.

“There are more than 130 independent, peer-reviewed published studies that show the efficacy and safety of low-carb eating,” she said. “The studies have been conducted for several decades and counting.” 
 

Expert perspective

Samantha Cassetty, a registered dietitian, nutritionist, and wellness expert in New York and author of Sugar Shock, reviewed the report for this news organization. She was not involved in the rankings.

“I think what this shows you is, the best diet overall is also the best for various conditions,” she said. For instance, the Mediterranean, the No. 1 overall, also got high ranking for diabetes, heart health, and bone and joint health.

For consumers trying to lose weight: “If you see fast weight loss, that should be a red flag. A healthy diet for weight loss is one you can sustain,” she said. 

She’s not a fan of the programs with prepackaged foods. “It takes the guesswork out, but the portion sizes tend to be unsatisfying. They don’t teach you how to deal with some of the challenges [such as realizing an ‘ideal’ portion size].”
 

How to use the report

Ms. Schueller’s advice: “Recognize that no diet fits everyone.” When considering which plan to choose, she suggests thinking long-term. 

“Whatever we choose has to work in the long run,” she said.

Consumers should consider expenses, meal prep time, and whether the diet fits their lifestyle.

Ideally, she said, the best diet “teaches you smart food preparation and how to make healthy choices, allows the flexibility to be social and eat with groups, whether family or friends.”

Before choosing a diet to follow, consult a medical professional for input on the decision, U.S. News cautioned.

“Our program is designed to address the needs of the individual through personalized experiences,” Jenny Craig CEO Mandy Dowson said. “We have many families that participate in our program together but are still evaluated separately to determine appropriate individual goals.”

Its high ranking for best diet program reflects feedback from satisfied members, she said. Among advances will be the new Jenny Fresh program, a line of entrées prepared fresh and delivered to customers’ doors.

Atkins got second place for best fast weight loss but ranked near the bottom for best overall, best weight loss, diabetes, healthy eating, and heart health. In response, Colette Heimowitz, vice president of nutrition and education for Simply Good Foods, which makes Atkins’s food products, said that low-carb eating approaches are a viable option for anyone today.

“There are more than 130 independent, peer-reviewed published studies that show the efficacy and safety of low-carb eating,” she said. “The studies have been conducted for several decades and counting.” 
 

Expert perspective

Samantha Cassetty, a registered dietitian, nutritionist, and wellness expert in New York and author of Sugar Shock, reviewed the report for this news organization. She was not involved in the rankings.

“I think what this shows you is, the best diet overall is also the best for various conditions,” she said. For instance, the Mediterranean, the No. 1 overall, also got high ranking for diabetes, heart health, and bone and joint health.

For consumers trying to lose weight: “If you see fast weight loss, that should be a red flag. A healthy diet for weight loss is one you can sustain,” she said. 

She’s not a fan of the programs with prepackaged foods. “It takes the guesswork out, but the portion sizes tend to be unsatisfying. They don’t teach you how to deal with some of the challenges [such as realizing an ‘ideal’ portion size].”
 

How to use the report

Ms. Schueller’s advice: “Recognize that no diet fits everyone.” When considering which plan to choose, she suggests thinking long-term. 

“Whatever we choose has to work in the long run,” she said.

Consumers should consider expenses, meal prep time, and whether the diet fits their lifestyle.

Ideally, she said, the best diet “teaches you smart food preparation and how to make healthy choices, allows the flexibility to be social and eat with groups, whether family or friends.”

Before choosing a diet to follow, consult a medical professional for input on the decision, U.S. News cautioned.

The Food and Drug Administration has approved semaglutide 2.4 mg (Wegovy), a once-weekly subcutaneous injection, for the additional indication of treating obesity in adolescents aged 12 years and older.

This is defined as those with an initial body mass index at or above the 95th percentile for age and sex (based on CDC growth charts). Semaglutide must be administered along with lifestyle intervention of a reduced calorie meal plan and increased physical activity.

When Wegovy was approved for use in adults with obesity in June 2021, it was labeled a “game changer.”

The new approval is based on the results of the STEP TEENS phase 3 trial of once-weekly 2.4 mg of semaglutide in adolescents 12- to <18 years old with obesity, the drug’s manufacturer, Novo Nordisk, announced in a press release.

In STEP TEENS, reported at Obesity Week 2022 in November, and simultaneously published in the New England Journal of Medicine, adolescents with obesity treated with semaglutide for 68 weeks had a 16.1% reduction in BMI compared with a 0.6% increase in BMI in those receiving placebo. Both groups also received lifestyle intervention. Mean weight loss was 15.3 kg (33.7 pounds) among teens on semaglutide, while those on placebo gained 2.4 kg (5.3 pounds).

At the time, Claudia K. Fox, MD, MPH, codirector of the Center for Pediatric Obesity Medicine at the University of Minnesota – who was not involved with the research – told this news organization the results were “mind-blowing ... we are getting close to bariatric surgery results” in these adolescent patients with obesity.

Semaglutide is a GLP-1 agonist, as is a related agent, also from Novo Nordisk, liraglutide (Saxenda), a daily subcutaneous injection, which was approved for use in adolescents aged 12 and older in December 2020. Wegovy is the first weekly subcutaneous injection approved for use in adolescents.

Other agents approved for obesity in those older than 12 in the United States include the combination phentermine and topiramate extended-release capsules (Qsymia) in June 2022, and orlistat (Alli). Phentermine is approved for those aged 16 and older.
