Obesity

Midlife women who are of normal weight or are overweight should routinely receive counseling aimed at limiting weight gain and preventing obesity and its associated health risks, a new clinical guideline states.

The recommendation, issued by the Women’s Preventive Services Initiative (WPSI) of the American College of Obstetricians and Gynecologists (ACOG), supports regular lifestyle counseling for women aged 40-60 years with normal or overweight body mass index of 18.5-29.9 kg/m². Counseling could include individualized discussion of healthy eating and physical activity initiated by health professionals involved in preventive care.

Published online in Annals of Internal Medicine, the guideline addresses the prevalence and health burdens of obesity in U.S. women of middle age and seeks to reduce the known harms of obesity with an intervention of minimal anticipated harms. High BMI increases the risk for many chronic conditions including hypertension, dyslipidemia, type 2 diabetes, coronary artery disease, stroke, and all-cause mortality.

The best way to counsel, however, remains unclear. “Although the optimal approach could not be discerned from existing trials, a range of interventions of varying duration, frequency, and intensity showed benefit with potential clinical significance,” wrote the WPSI guideline panel, led by David P. Chelmow, MD, chair of the department of obstetrics and gynecology at Virginia Commonwealth University in Richmond.

The guideline rests on a systematic literature review led by family doctor Amy G. Cantor, MD, MPH, of the Pacific Northwest Evidence-based Practice Center, at Oregon Health & Science University in Portland, suggesting moderate reductions in weight could be achieved by offering advice to this age group.

The federally supported WPSI was launched by ACOG in 2016. The guideline fills a gap in current recommendations in that it targets a specific risk group and specifies individual counseling based on its effectiveness and applicability in primary care settings.

In another benefit of routine counseling, the panel stated, “Normalizing counseling about healthy diet and physical activity by providing it to all midlife women may also mitigate concerns about weight stigma resulting from only counseling women with obesity.”

The panelists noted that during 2017-2018, the prevalence of obesity (BMI ≥ 30.0 kg/m²) was 43.3% among U.S. women aged 40-59 years, while the prevalence of severe obesity (BMI ≥ 40.0 kg/m²) was highest in this age group at 11.5%. “Midlife women gain weight at an average of approximately 1.5 pounds per year, which increases their risk for transitioning from normal or overweight to obese BMI,” the panelists wrote.

The review

Dr. Cantor’s group analyzed seven randomized controlled trials (RCTs) published up to October 2021 from 12 publications involving 51,638 participants. Although the trials were largely small and heterogeneous, they suggested that counseling may result in modest differences in weight change without causing important harms.

Four RCTs showed significant favorable weight changes for counseling over no-counseling control groups, with a mean difference of 0.87 to 2.5 kg, whereas one trial of counseling and two trials of exercise showed no differences. One of two RCTs reported improved quality-of-life measures.

As for harms, while interventions did not increase measures of depression or stress in one trial, self-reported falls (37% vs. 29%, P < .001) and injuries (19% vs. 14%, P = .03) were more frequent with exercise counseling in one trial.

“More research is needed to determine optimal content, frequency, length, and number of sessions required and should include additional patient populations,” Dr. Cantor and associates wrote.

In terms of limitations, the authors acknowledged that trials of behavioral interventions in maintaining or reducing weight in midlife women demonstrate small magnitudes of effect.

Offering a nonparticipant’s perspective on the WPSI guideline for this news organization, JoAnn E. Manson, MD, DrPH, MACP, chief of the division of preventive medicine at Brigham and Women’s Hospital in Boston, said its message is of prime importance for women of middle age and it goes beyond concern about pounds lost or gained.

“Midlife and the transition to menopause are high-risk periods for women in terms of typical changes in body composition that increase the risk of adverse cardiometabolic outcomes,” said Dr. Manson, professor of women’s health at Harvard Medical School, Boston. “Counseling women should be a priority for physicians in clinical practice. And it’s not just whether weight gain is reflected on the scales or not but whether there’s an increase in central abdominal fat, a decrease in lean muscle mass, and an increase in adverse glucose tolerance.”

It is essential for women to be vigilant at this time, she added, and their exercise regimens should include strength and resistance training to preserve lean muscle mass and boost metabolic rate. Dr. Manson’s group has issued several statements stressing how important it is for clinicians to take decisive action on the counseling front and how they can do this in very little time during routine practice.

Also in full support of the guideline is Mary L. Rosser, MD, PhD, assistant professor of women’s health in obstetrics and gynecology at Columbia University Irving Medical Center in New York. “Midlife is a wonderful opportunity to encourage patients to assess their overall health status and make changes to impact their future health. Women in middle age tend to experience weight gain due to a variety of factors including aging and lifestyle,” said Dr. Rosser, who was not involved in the writing of the review or guideline.

While aging and genetics cannot be altered, behaviors can, and in her view, favorable behaviors would also include stress reduction and adequate sleep.

“The importance of reducing obesity with early intervention and prevention must focus on all women,” Dr. Rosser said. “We must narrow the inequities gap in care especially for high-risk minority groups and underserved populations. This will reduce disease and death and provide women the gift of active living and feeling better.”

The WPSI authors have made available a summary of the review and guideline for patients.

The systematic review and clinical guideline were funded by the federal Health Resources and Services Administration through ACOG. The authors of the guideline and the review authors disclosed no relevant financial conflicts of interest. Dr. Manson and Dr. Rosser disclosed no relevant competing interests with regard to their comments.

“Children’s hospitals saw a more than 25% decline in injury-related emergency room visits during the first year of the pandemic.” There’s a headline that should soothe a nation starved for some good news. It was based on a study published in Pediatrics that reports on data collected in the Pediatric Health Information System between March 2020 and March 2021 using a 3-year period between 2017 and 2020 as a control. How could this not be good news? First, let’s not be too hasty in celebrating the good fortune of all those millions of children spared the pain and anxiety of an emergency department visit.

If you were an administrator of an emergency department attempting to match revenues with expenses, a 25% drop in visits may have hit your bottom line. Office-based pediatricians experienced a similar phenomenon when many parents quickly learned that they could ignore or self-manage minor illnesses and complaints.

A decrease in visits doesn’t necessarily mean that the conditions that drive the traffic flow in your facility have gone away. It may simply be that they are being managed somewhere else. However, it is equally likely that for some reason the pandemic created situations that made the usual illnesses and injuries that flood into emergency departments less likely to occur. And, here, other anecdotal evidence about weight gain and a decline in fitness point to the conclusion that when children are no longer in school, they settle into more sedentary and less injury-generating activities. Injuries from falling off the couch watching television or playing video games alone do occur but certainly with less frequency than the random collisions that are inevitable when scores of classmates are running around on the playground.

So while it may be tempting to view a decline in emergency department visits as a positive statistic, this pandemic should remind us to be careful about how we choose our metrics to measure the health of the community. A decline in injuries in the short term may be masking a more serious erosion in the health of the pediatric population over the long term. At times I worry that as a specialty we are so focused on injury prevention that we lose sight of the fact that being physically active comes with a risk. A risk that we may wish to minimize, but a risk we must accept if we want to encourage the physical activity that we know is so important in the bigger health picture. For example, emergency department visits caused by pedal cycles initially rose 60%, eventually settling into the 25%-30% range leading one to suspect there was a learning or relearning curve.

However, while visits for minor injuries declined 25%, those associated with firearms rose initially 22%, and then 42%, and finally over 35%. These numbers combined with significant increases in visits from suffocation, nonpedal transportation, and suicide intent make it clear that, for most children, being in school is significantly less dangerous than staying at home.

As the pandemic continues to tumble on and we are presented with future questions about whether to keep schools open or closed, I hope the results of this study and others will help school officials and their advisers step back and look beyond the simple metric of case numbers and appreciate that there are benefits to being in school that go far beyond what can be learned in class.

The global prevalence of fatty liver disease not caused by alcohol is considerably higher than previously estimated and is continuing to increase at an alarming rate, report researchers from Canada.

Their analysis suggests nearly one-third of the global general adult population has nonalcoholic fatty liver disease (NAFLD), with men much more likely to have the disease than women.

“Greater awareness of NAFLD and the development of cost-effective risk stratification strategies are needed to address the growing burden NAFLD,” wrote Abdel-Aziz Shaheen, MBBCh, MSc, and colleagues with the University of Calgary (Alta.).

The study was published online in Lancet Gastroenterology and Hepatology.

NAFLD is the most common liver disease worldwide and a leading cause of liver-related illness and death. Yet, high-quality reports on the epidemiology of NAFLD at a global level are scarce and temporal trends of the NAFLD burden, including by gender, have not been described, until now.

Using MEDLINE, EMBASE, Scopus, and Web of Science, the Calgary team identified reports on NAFLD incidence and prevalence in study populations representative of the general adult population published between the date of database inception to May 25, 2021.

In total, 72 publications, with a sample population of more than 1 million adults from 17 countries, were included in the prevalence analysis, and 16 publications, with a sample population of nearly 382,000 individuals from five countries, were included in the incidence analysis.

By their estimates, the overall global prevalence of NAFLD is 32.4%, with prevalence increasing steadily and significantly over time, from 25.5% in or before 2005 to 37.8% in 2016 or later. The overall prevalence is significantly higher in men than in women (39.7% vs. 25.6%).

These figures contrast with recent meta-analyses and systematic reviews that put the global prevalence of NAFLD at between 25.2% and 29.8%. However, these studies had “considerable” limitations with “potentially biased inferences,” Dr. Shaheen and colleagues noted.

By region, their data put the prevalence of NAFLD at 31.6% in Asia, 32.6% in Europe, 47.8% in North America, and 56.8% in Africa.

Dr. Shaheen and colleagues estimate the overall incidence of NAFLD to be 46.9 cases per 1,000 person-years, with a higher incidence in men than women (70.8 vs. 29.6 cases per 1000 person-years), in line with the gender differences in prevalence.

They caution that there was “considerable” heterogeneity between studies in both NAFLD prevalence and incidence (I₂ = 99.9%) and few “high-quality” studies.

Despite these limitations, Dr. Shaheen and colleagues said the rise in NAFLD prevalence “should drive enhanced awareness of NAFLD at the level of primary care physicians, public health specialists, and health policy makers to encourage the development of more effective preventive policies.”

Funding for the study was provided by the Canadian Institutes of Health. Dr. Shaheen has received research grants from Gilead and Intercept, and honoraria from SCOPE Canada.

NAFLD is the most common liver disease worldwide and a leading cause of liver-related illness and death. Yet, high-quality reports on the epidemiology of NAFLD at a global level are scarce and temporal trends of the NAFLD burden, including by gender, have not been described, until now.

Using MEDLINE, EMBASE, Scopus, and Web of Science, the Calgary team identified reports on NAFLD incidence and prevalence in study populations representative of the general adult population published between the date of database inception to May 25, 2021.

In total, 72 publications, with a sample population of more than 1 million adults from 17 countries, were included in the prevalence analysis, and 16 publications, with a sample population of nearly 382,000 individuals from five countries, were included in the incidence analysis.

By their estimates, the overall global prevalence of NAFLD is 32.4%, with prevalence increasing steadily and significantly over time, from 25.5% in or before 2005 to 37.8% in 2016 or later. The overall prevalence is significantly higher in men than in women (39.7% vs. 25.6%).

These figures contrast with recent meta-analyses and systematic reviews that put the global prevalence of NAFLD at between 25.2% and 29.8%. However, these studies had “considerable” limitations with “potentially biased inferences,” Dr. Shaheen and colleagues noted.

By region, their data put the prevalence of NAFLD at 31.6% in Asia, 32.6% in Europe, 47.8% in North America, and 56.8% in Africa.

Dr. Shaheen and colleagues estimate the overall incidence of NAFLD to be 46.9 cases per 1,000 person-years, with a higher incidence in men than women (70.8 vs. 29.6 cases per 1000 person-years), in line with the gender differences in prevalence.

They caution that there was “considerable” heterogeneity between studies in both NAFLD prevalence and incidence (I₂ = 99.9%) and few “high-quality” studies.

Despite these limitations, Dr. Shaheen and colleagues said the rise in NAFLD prevalence “should drive enhanced awareness of NAFLD at the level of primary care physicians, public health specialists, and health policy makers to encourage the development of more effective preventive policies.”

Funding for the study was provided by the Canadian Institutes of Health. Dr. Shaheen has received research grants from Gilead and Intercept, and honoraria from SCOPE Canada.

U.S. children appear to be failing an important test – of their hearts, not minds.

New research from the Ann & Robert H. Lurie Children’s Hospital of Chicago shows that heart health is a concern for many long before adulthood because fewer than one-third of children aged 2-19 years scored highly on the American Heart Association’s checklist for ideal cardiovascular fitness.

“This study gives us a new baseline for children’s heart health in the United States,” said Amanda Perak, MD, pediatric cardiologist at Ann & Robert H. Lurie Children’s Hospital of Chicago and a coauthor of the study.

Dr. Perak and colleagues published their findings in the journal Circulation.

The researchers identified 9888 children who completed the Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey between 2013 and 2018. They analyzed the available data using the AHA’s Life’s Essential 8 – a 100-point assessment of eight predictors for measuring heart health, including sleep, nicotine exposure, and blood glucose.

Data for only three metrics were available for all children in the study: diet, physical activity, and body mass index. As children aged, more metrics were averaged to obtain the overall cardiovascular health score. For instance, cholesterol/lipid levels become available at age 6 years, and blood pressure can be measured starting at age 8 years.

Only 2.2% of children in the study had optimal heart health, according to the Life’s Essential 8 scoring system, which spans poor (0-49), moderate (50-79), and high (80-100). Fewer than one in three (29.1%) overall had high scores, and scores worsened with age.

In the 2- to 5-year age group, over half (56.5%) of the children had good heart health. However, only one-third (33.5%) of 6- to 11-year-olds scored highly. Meanwhile, only 14% of adolescents had good heart scores, Dr. Perak’s group found.

Heart health scores based on diet were lowest for every age group. In the youngest age group, the average cardiovascular health (CVH) score was about 61. In the 12- to 19-year age group, however, the average CVH score decreased to 28.5, the lowest measured score for any group in the study.

With such worrisome diet scores for the 12- to 19-year-old group, public health policies need to focus on changes, like removing sugar-sweetened beverage options from schools, according to Joseph Mahgerefteh, MD, director of preventive cardiology at the Mount Sinai Kravis Children’s Heart Center, New York. He added that parents and their children also have a role to play.

“Some of our teenagers forget they can drink water when they are thirsty, and it is not necessary to drink sugar-sweetened beverages for thirst,” Dr. Mahgerefteh, who was not involved in the study, said in an interview. “Fresh vegetable intake is so low to a degree that some of our patients refuse to have any type of vegetable in their diet.”

“As a physician community caring for these patients, we need to be much more aggressive with our counseling and referral of these patients,” added Barry Love, MD, director of the congenital cardiac catheterization program at the Mount Sinai Kravis Children’s Heart Center. “These youngsters will inevitably encounter the effect of these conditions – coronary artery disease and stroke – at a much earlier adult age.”

Dr. Perak, Dr. Mahgerefteh, and Dr. Love reported no relevant financial conflicts of interest.

The Food and Drug Administration has cleared for marketing the first devices indicated for endoscopic sleeve gastroplasty (ESG) and endoscopic bariatric revision, according to the manufacturer.

The Apollo ESG, Apollo ESG Sx, Apollo Revise, and Apollo Revise Sx systems made by Apollo Endosurgery were reviewed through the de novo premarket review pathway, a regulatory pathway for low- to moderate-risk devices of a new type.

“The Apollo ESG and Apollo Revise systems offer a compelling mix of effectiveness, safety, durability, and convenience for treatment of patients with obesity,” Chas McKhann, president and CEO of the company, said in a news release.

“The authorization of these new endoscopic systems represents a major step forward in addressing the global obesity epidemic,” Mr. McKhann added.

The Apollo ESG and Apollo ESG Sx systems are intended for use by trained gastroenterologists or surgeons to facilitate weight loss in adults with obesity who have failed to lose weight or maintain weight loss through more conservative measures, the company says.

The Apollo Revise and Apollo Revise Sx systems allow gastroenterologists or surgeons to perform transoral outlet reduction (TORe) as a revision to a previous bariatric procedure.

Studies have shown that 10 years after bariatric surgery, patients have regained an average of 20%-30% of weight they initially lost. Bariatric revision procedures are the fastest growing segment of the bariatric surgery market.

TORe is an endoscopic procedure performed to revise a previous gastric bypass and like ESG, can be performed as a same-day procedure without incisions or scars.

Avocados are a rich source of fiber and healthy fat, but eating one a day for 6 months did not shrink waist size or belly fat, according to the findings of a new study.

But it did improve diet quality and led to modest lowering of total cholesterol.

More than 1,000 adults with overweight or obesity and a large waist – at least 35 inches in women and 40 inches in men – took part in this U.S. study, called the Habitual Diet and Avocado Trial (HAT).

tookapic/Pixabay

The people in the study were divided into two groups: usual diet plus one large avocado every day and usual diet with two avocados at most per month (control group).

Those in the avocado-a-day group were given a regular supply of fresh avocados along with written instructions for how to ripen and prepare them.

They had MRI scans to measure belly fat and fat around other organs at the beginning of the study and after 6 months.

After 6 months, the people who ate an avocado a day did not have less fat around their middles – the main trial outcome – compared with people in the control group.

But at 6 months, those in the avocado-a-day group had:

• No weight gain. People’s weight remained stable in both groups.
• Improved diet quality by 8 points on a 100-point scale
• A 2.9-mg/dL decrease in total cholesterol
• A 2.5-mg/dL decrease in LDL cholesterol

The study was done by researchers at Penn State University; Tufts University; Loma Linda University; and the University of California, Los Angeles, with coordinating support from Wake Forest University.

It was published in the Journal of the American Heart Association.

“While the avocados did not affect belly fat or weight gain, the study still provides evidence that avocados can be a beneficial addition to a well-balanced diet,” Penny M. Kris-Etherton, PhD, one of the researchers and a professor of nutritional sciences at Penn State University, University Park, said in a news release.

“Incorporating an avocado per day in this study did not cause weight gain and also caused a slight decrease in LDL cholesterol, which are all important findings for better health,” she said.

Similarly, study researcher Joan Sabaté, MD, a professor at Loma Linda (Calif.) University, said: “While one avocado a day did not lead to clinically significant improvements in abdominal fat and other cardiometabolic risk factors, consuming one avocado a day did not result in body weight gain.”

“This is positive,” he said, “because eating extra calories from avocados doesn’t impact body weight or abdominal fat, and it slightly decreases total and LDL cholesterol.”

Kristina S. Petersen, PhD, another of the researchers and an assistant professor of nutritional sciences at Texas Tech University, Lubbock, pointed out that people are generally poor at adhering to the Dietary Guidelines for Americans.

This study suggests that an avocado a day can improve diet quality, she noted, which “ is important because we know a higher diet quality is associated with lower risk of several diseases, including heart disease, type 2 diabetes, and some cancers.”

But the researchers also stressed that it is important to consider the diet as a whole.

“Consistent with prior observations, a change in dietary patterns rather than a single food or nutrient may be necessary to achieve clinically significant improvements” in belly fat and other risk factors for heart attack, stroke, and diabetes, they wrote. 

HAT was funded by the Hass Avocado Board, which also supplied the avocados.

Pediatric obesity is a serious problem, not only in the United States but worldwide. Unfortunately, the ongoing COVID-19 pandemic has worsened the epidemic of childhood obesity. Solutions for treating the millions of children and adolescents with obesity are desperately needed because prevention efforts over the past several decades have not been sufficient in slowing the steady rise in obesity prevalence.

Lifestyle modification, including dietary changes, increases in activity, and behavioral modification, are the cornerstone of any obesity treatment, but they alone are not powerful enough to treat obesity by itself in the vast majority of children and adolescents. This is because obesity is not a lifestyle choice; rather, it is a disease, and a disease that has a tremendous amount of biology driving individuals toward weight gain and the propensity toward weight regain if weight is lost.

Fortunately, the tools to treat the underlying biology driving obesity are becoming safer, more effective, and more widely used every year. The two most effective biology-based treatments for pediatric obesity are antiobesity medications and bariatric surgery. These two treatments, when accompanied by lifestyle modification, have the potential to reduce not only body weight but also treat many other risk factors, such as prediabetes, diabetes, high blood pressure, poor cholesterol, liver disease, and sleep apnea, as well as others.
 

Rise in antiobesity medications

Antiobesity medications are developing at a rapid pace. Seven medications have been approved by the Food and Drug Administration for adults, and three medications (phentermine, orlistat, and liraglutide) are now approved for children and adolescents.

The number of antiobesity medications for use in children and adolescents is expected to expand to five, with semaglutide and phentermine-topiramate (Qsymia) both completing trials in adolescents in 2022. Each of these medications works by treating the biology that drives weight gain, whether it is decreasing impulsivity, reducing hunger and appetite hormone pathways, or improving energy regulation pathways. Weight loss at 1 year for currently FDA-approved medications in adolescents ranges from 3% to 6% on average, depending on the medications. The newer medications already FDA approved in adults that will soon, hopefully, be available in pediatrics result in 10%-16% weight loss on average.

A common parent and patient question regarding antiobesity medications is: “If I start an antiobesity medication, how long will I need to be on it?” The simple answer is: “Probably for the rest of your life.”

This can be a shock to hear, but obesity treatment is very similar to that of hypertension or diabetes. Using high blood pressure as an example: If a patient has high blood pressure (for example, 160/90 mm Hg), they will be prescribed a medication to treat it. Once blood pressure comes down to near-normal levels (for example, 120/80 mm Hg), a dose will be maintained, not removed, because that is the biological mediator keeping the blood pressure low. Removal of the medication would result in blood pressure going back to homeostasis (160/90 mm Hg in our example) in a short period of time).

The same can be said for obesity. For example, if a 16-year-old girl is prescribed liraglutide, a glucagonlike peptide–1 receptor agonist, and loses 10% of her body weight at 1 year, that is great success. Why would we remove the medication that is treating the underlying biology causing successful weight loss?

In short, we would not want to do that. Even if our example patient only maintained that 10% initial weight loss, that would be very successful, just like someone maintaining their low blood pressure. As medications begin to develop at a rapid pace and become more available to pediatric patients, the messaging and conversation around anti-obesity medications must continue to focus on obesity being a biological disease and not a behavior for treatment to be effective and not stigmatized.
 

Bariatric surgery most effective treatment for pediatric obesity

Currently, the most effective treatment for pediatric obesity is bariatric surgery. The two most commonly used surgical procedures today are the sleeve gastrectomy and gastric bypass. Sleeve gastrectomy works by removing 75%-85% of the stomach and creating a new stomach, called a “sleeve.” Gastric bypass works by separating the stomach into two parts and connecting one part of the new stomach into the intestine.

Both surgeries are very effective at treating obesity in adolescents, with an average weight loss of 30%-35%. Surgery is not just a restrictive means of controlling body weight; it also changes key hormones for appetite and satiety that signal the brain. In fact, many of the same biological signals that are changed by surgery are the same signals being targeted by antiobesity medications. Long-term outcome of bariatric surgery in adolescents, provided by Teen-LABS, show it to be safe and maybe even more effective than in adults for treating diabetes and hypertension, with similar weight loss.
 

Does treatment outweigh the potential risks?

Although obesity surgery and antiobesity medications are more successful at treating obesity in children and adolescents than lifestyle medications, they do have some risks. Surgery, depending on the type of surgery, can cause nutritional deficiencies, reduce body mineral density, and is a life-changing medical procedure. Antiobesity medications, depending on the type, can cause nausea and vomiting and increase heart rate – and because they are relatively new, we do not fully understand the long-term impact of continued use past 1 year.

However, an important question to ask is: “Do the risks of obesity surgery and antiobesity medications outweigh the risk of having lifelong obesity?” The answer to me and many of my colleagues is: “Yes!” Although there are risks associated with the two best treatments for pediatric obesity, those risks under proper supervision of a medical professional far outweigh the risks of not properly treating obesity and allowing it to persist and get worse over many years to come. Obesity is a disease deeply rooted in biology, and we must use biology-based treatments to tackle this problem in children and adolescents, who deserve the best care and treatments possible.

This is because obesity is not a lifestyle choice; rather, it is a disease, and a disease that has a tremendous amount of biology driving individuals toward weight gain and the propensity toward weight regain if weight is lost.

Fortunately, the tools to treat the underlying biology driving obesity are becoming safer, more effective, and more widely used every year. The two most effective biology-based treatments for pediatric obesity are antiobesity medications and bariatric surgery. These two treatments, when accompanied by lifestyle modification, have the potential to reduce not only body weight but also treat many other risk factors, such as prediabetes, diabetes, high blood pressure, poor cholesterol, liver disease, and sleep apnea, as well as others.
 

Rise in antiobesity medications

Antiobesity medications are developing at a rapid pace. Seven medications have been approved by the Food and Drug Administration for adults, and three medications (phentermine, orlistat, and liraglutide) are now approved for children and adolescents.

The number of antiobesity medications for use in children and adolescents is expected to expand to five, with semaglutide and phentermine-topiramate (Qsymia) both completing trials in adolescents in 2022. Each of these medications works by treating the biology that drives weight gain, whether it is decreasing impulsivity, reducing hunger and appetite hormone pathways, or improving energy regulation pathways. Weight loss at 1 year for currently FDA-approved medications in adolescents ranges from 3% to 6% on average, depending on the medications. The newer medications already FDA approved in adults that will soon, hopefully, be available in pediatrics result in 10%-16% weight loss on average.

A common parent and patient question regarding antiobesity medications is: “If I start an antiobesity medication, how long will I need to be on it?” The simple answer is: “Probably for the rest of your life.”

This can be a shock to hear, but obesity treatment is very similar to that of hypertension or diabetes. Using high blood pressure as an example: If a patient has high blood pressure (for example, 160/90 mm Hg), they will be prescribed a medication to treat it. Once blood pressure comes down to near-normal levels (for example, 120/80 mm Hg), a dose will be maintained, not removed, because that is the biological mediator keeping the blood pressure low. Removal of the medication would result in blood pressure going back to homeostasis (160/90 mm Hg in our example) in a short period of time).

The same can be said for obesity. For example, if a 16-year-old girl is prescribed liraglutide, a glucagonlike peptide–1 receptor agonist, and loses 10% of her body weight at 1 year, that is great success. Why would we remove the medication that is treating the underlying biology causing successful weight loss?

In short, we would not want to do that. Even if our example patient only maintained that 10% initial weight loss, that would be very successful, just like someone maintaining their low blood pressure. As medications begin to develop at a rapid pace and become more available to pediatric patients, the messaging and conversation around anti-obesity medications must continue to focus on obesity being a biological disease and not a behavior for treatment to be effective and not stigmatized.
 

Bariatric surgery most effective treatment for pediatric obesity

Currently, the most effective treatment for pediatric obesity is bariatric surgery. The two most commonly used surgical procedures today are the sleeve gastrectomy and gastric bypass. Sleeve gastrectomy works by removing 75%-85% of the stomach and creating a new stomach, called a “sleeve.” Gastric bypass works by separating the stomach into two parts and connecting one part of the new stomach into the intestine.

Both surgeries are very effective at treating obesity in adolescents, with an average weight loss of 30%-35%. Surgery is not just a restrictive means of controlling body weight; it also changes key hormones for appetite and satiety that signal the brain. In fact, many of the same biological signals that are changed by surgery are the same signals being targeted by antiobesity medications. Long-term outcome of bariatric surgery in adolescents, provided by Teen-LABS, show it to be safe and maybe even more effective than in adults for treating diabetes and hypertension, with similar weight loss.
 

Does treatment outweigh the potential risks?

Although obesity surgery and antiobesity medications are more successful at treating obesity in children and adolescents than lifestyle medications, they do have some risks. Surgery, depending on the type of surgery, can cause nutritional deficiencies, reduce body mineral density, and is a life-changing medical procedure. Antiobesity medications, depending on the type, can cause nausea and vomiting and increase heart rate – and because they are relatively new, we do not fully understand the long-term impact of continued use past 1 year.

However, an important question to ask is: “Do the risks of obesity surgery and antiobesity medications outweigh the risk of having lifelong obesity?” The answer to me and many of my colleagues is: “Yes!” Although there are risks associated with the two best treatments for pediatric obesity, those risks under proper supervision of a medical professional far outweigh the risks of not properly treating obesity and allowing it to persist and get worse over many years to come. Obesity is a disease deeply rooted in biology, and we must use biology-based treatments to tackle this problem in children and adolescents, who deserve the best care and treatments possible.

Pediatric obesity is a serious problem, not only in the United States but worldwide. Unfortunately, the ongoing COVID-19 pandemic has worsened the epidemic of childhood obesity.

Children whose mothers have polycystic ovary syndrome (PCOS) have increased rates of hospitalization for various conditions, including asthma, pneumonia, and ear infection, a study of more than 1 million children shows.

The associations were not particularly strong, according to the researchers. But they raise questions about the reasons for the increased risk and whether interventions such as diet, exercise, or medications could lead to healthier outcomes for children whose mothers have PCOS.

“The findings suggest that maternal PCOS may have a negative impact on offspring development, enough to lead to a measurable increase in the risk of childhood hospitalization,” study coauthor Nathalie Auger, MD, associate professor of epidemiology at University of Montreal, and colleagues reported in Human Reproduction.

“They are minor differences, just enough that we can statistically identify them. They’re not something where everyone should be worrying at this point,” Dr. Auger told this news organization.

Still, some of the hospitalizations, such as those related to infection or allergy, could be prevented with earlier ambulatory care, so some degree of greater awareness among parents and clinicians may be warranted, she said.
 

Thirteen years of follow-up

PCOS – a reproductive disorder characterized by irregular periods, increased male hormones, and metabolic complications – affects some 10% of women. People with the condition are at increased risk for obesity, type 2 diabetes, and cardiovascular disease.

Although prior research has shown that maternal PCOS may be associated with higher body mass index and attention deficit disorder in children, data on long-term childhood health outcomes have been limited, Dr. Auger’s group noted.

To examine illness in children exposed to maternal PCOS, the investigators analyzed hospitalization rates for nearly 1.04 million children in Quebec between 2006 and 2020; 7,160 of the children had mothers with PCOS.

In all, 275,354 children were hospitalized during 13 years of follow-up, including 2,314 whose mothers had PCOS.

Children exposed to PCOS were hospitalized at a rate of 68.9 per 1,000 person-years – roughly 50% more often than the rate of 45.3 per 1,000 person-years for children not exposed to maternal PCOS.

In an analysis that adjusted for maternal characteristics, childhood hospitalization for any reason was 1.32 times more likely for children exposed to maternal PCOS.

Hospitalizations linked to infectious diseases – such as for bronchitis, bronchiolitis, pneumonia, nephritis, otitis media, or meningitis – were 1.31 times more likely among children exposed to PCOS. Allergy-related hospitalizations, such as for allergic asthma and anaphylaxis, were 1.47 times more likely, according to the researchers.

Metabolic hospitalizations were 1.59 times more likely. For gastrointestinal hospitalizations, the hazard ratio was 1.72. For central nervous system hospitalizations, it was 1.74.

The associations were stronger in earlier childhood, and results were similar for boys and girls, the investigators reported.

Hospitalizations for cardiovascular disease, musculoskeletal conditions, or malignancy were not increased.
 

‘Surprising’ links

“The findings are surprising in that some of the conditions that they showed increased risk for, like asthma and some infections, are not conditions that we think of as being typically associated with PCOS,” said Andrea E. Dunaif, MD, chief of the Hilda and J. Lester Gabrilove Division of Endocrinology, Diabetes, and Bone Disease at Mount Sinai Health System, New York, who was not part of the study team.

Earlier studies of offspring of women with PCOS have suggested that children may be at increased risk for insulin resistance and obesity.

Differences in genetics, intrauterine environments, patterns of health care use by women with PCOS, and behavioral factors, such as diet and how children are raised, are variables that could have contributed to the different hospitalization rates among children exposed to maternal PCOS, Dr. Auger said.

“Everything is interconnected,” she said.

The study was supported by a grant from the Canadian Institutes of Health Research. Dr. Auger has received a career award from Fonds de Recherche du Québec-Santé. Dr. Dunaif has consulted for Novo Nordisk and Fractyl Laboratories (now Fractyl Health).

The notion that people get ‘hangry’ – irritable and short-tempered when they’re hungry – is such an established part of modern folklore that the word has even been added to the Oxford English Dictionary. Although experimental studies in the past have shown that low blood glucose levels increase impulsivity, anger, and aggression, there has been little solid evidence that this translates to real-life settings.

Now new research has confirmed that the phenomenon does really exist in everyday life. The study, published in the journal PLOS ONE, is the first to investigate how hunger affects people’s emotions on a day-to-day level. Lead author Viren Swami, professor of social psychology at Anglia Ruskin University, Cambridge, England, said: “Many of us are aware that being hungry can influence our emotions, but surprisingly little scientific research has focused on being ‘hangry’.”

He and coauthors from Karl Landsteiner University of Health Sciences in Krems an der Donau, Austria, recruited 64 participants from Central Europe who completed a 21-day experience sampling phase, in which they were prompted to report their feelings on a smartphone app five times a day. At each prompt, they reported their levels of hunger, anger, irritability, pleasure, and arousal on a visual analog scale.

Participants were on average 29.9 years old (range = 18-60), predominantly (81.3%) women, and had a mean body mass index of 23.8 kg/m² (range 15.8-36.5 kg/m²).

Anger was rated on a 5-point scale but the team explained that the effects of hunger are unlikely to be unique to anger per se, so they also asked about experiences of irritability and, in order to obtain a more holistic view of emotionality, also about pleasure and arousal, as indexed using Russell’s affect grid.

They also asked about eating behaviors over the previous 3 weeks, including frequency of main meals, snacking behavior, healthy eating, feeling hungry, and sense of satiety, and about dietary behaviors including restrictive eating, emotionally induced eating, and externally determined eating behavior.

Analysis of the resulting total of 9,142 responses showed that higher levels of self-reported hunger were associated with greater feelings of anger and irritability, and with lower levels of pleasure. These findings remained significant after accounting for participants’ sex, age, body mass index, dietary behaviors, and trait anger. However, associations with arousal were not significant.

The authors commented that the use of the app allowed data collection to take place in subjects’ everyday environments, such as their workplace and at home. “These results provide evidence that everyday levels of hunger are associated with negative emotionality and supports the notion of being ‘hangry.’ ”
 

‘Substantial’ effects

“The effects were substantial,” the team said, “even after taking into account demographic factors” such as age and sex, body mass index, dietary behavior, and individual personality traits. Hunger was associated with 37% of the variance in irritability, 34% of the variance in anger, and 38% of the variance in pleasure recorded by the participants.

The research also showed that the negative emotions – irritability, anger, and unpleasantness – were caused by both day-to-day fluctuations in hunger and residual levels of hunger measured by averages over the 3-week period.

The authors said their findings “suggest that the experience of being hangry is real, insofar as hunger was associated with greater anger and irritability, and lower pleasure, in our sample over a period of 3 weeks.

“These results may have important implications for understanding everyday experiences of emotions, and may also assist practitioners to more effectively ensure productive individual behaviors and interpersonal relationships (for example, by ensuring that no one goes hungry).”

Although the majority of participants (55%) said they paid attention to hunger pangs, only 23% said that they knew when they were full and then stopped eating, whereas 63% said they could tell when they were full but sometimes continued to eat. Few (4.7%) people said they could not tell when they were full and therefore oriented their eating based on the size of the meal, but 9% described frequent overeating because of not feeling satiated, and 13% stated they ate when they were stressed, upset, angry, or bored.

Professor Swami said: “Ours is the first study to examine being ‘hangry’ outside of a lab. By following people in their day-to-day lives, we found that hunger was related to levels of anger, irritability, and pleasure.

“Although our study doesn’t present ways to mitigate negative hunger-induced emotions, research suggests that being able to label an emotion can help people to regulate it, such as by recognizing that we feel angry simply because we are hungry. Therefore, greater awareness of being ‘hangry’ could reduce the likelihood that hunger results in negative emotions and behaviors in individuals.”

They also asked about eating behaviors over the previous 3 weeks, including frequency of main meals, snacking behavior, healthy eating, feeling hungry, and sense of satiety, and about dietary behaviors including restrictive eating, emotionally induced eating, and externally determined eating behavior.

Analysis of the resulting total of 9,142 responses showed that higher levels of self-reported hunger were associated with greater feelings of anger and irritability, and with lower levels of pleasure. These findings remained significant after accounting for participants’ sex, age, body mass index, dietary behaviors, and trait anger. However, associations with arousal were not significant.

The authors commented that the use of the app allowed data collection to take place in subjects’ everyday environments, such as their workplace and at home. “These results provide evidence that everyday levels of hunger are associated with negative emotionality and supports the notion of being ‘hangry.’ ”
 

‘Substantial’ effects

“The effects were substantial,” the team said, “even after taking into account demographic factors” such as age and sex, body mass index, dietary behavior, and individual personality traits. Hunger was associated with 37% of the variance in irritability, 34% of the variance in anger, and 38% of the variance in pleasure recorded by the participants.

The research also showed that the negative emotions – irritability, anger, and unpleasantness – were caused by both day-to-day fluctuations in hunger and residual levels of hunger measured by averages over the 3-week period.

The authors said their findings “suggest that the experience of being hangry is real, insofar as hunger was associated with greater anger and irritability, and lower pleasure, in our sample over a period of 3 weeks.

“These results may have important implications for understanding everyday experiences of emotions, and may also assist practitioners to more effectively ensure productive individual behaviors and interpersonal relationships (for example, by ensuring that no one goes hungry).”

Although the majority of participants (55%) said they paid attention to hunger pangs, only 23% said that they knew when they were full and then stopped eating, whereas 63% said they could tell when they were full but sometimes continued to eat. Few (4.7%) people said they could not tell when they were full and therefore oriented their eating based on the size of the meal, but 9% described frequent overeating because of not feeling satiated, and 13% stated they ate when they were stressed, upset, angry, or bored.

Professor Swami said: “Ours is the first study to examine being ‘hangry’ outside of a lab. By following people in their day-to-day lives, we found that hunger was related to levels of anger, irritability, and pleasure.

“Although our study doesn’t present ways to mitigate negative hunger-induced emotions, research suggests that being able to label an emotion can help people to regulate it, such as by recognizing that we feel angry simply because we are hungry. Therefore, greater awareness of being ‘hangry’ could reduce the likelihood that hunger results in negative emotions and behaviors in individuals.”

INDIANAPOLIS – Nearly two-thirds of pediatric patients with hidradenitis suppurativa (HS) met criteria for obesity at the time of their diagnosis, and 36% had acne, in a study presented at the annual meeting of the Society for Pediatric Dermatology.

In addition, 44% presented with scarring, which suggests that HS may be underdiagnosed in this patient population. Those are the key findings from the study, a single-center retrospective chart review presented by Stephanie Sanchez during a poster session at the meeting.

“There is limited research on HS within the pediatric population,” said Ms. Sanchez, a fourth-year medical student at Boston University. “It’s not very well defined or characterized.” The “unusually high number of pediatric patients with HS” at Boston Medical Center provided “a unique opportunity to study this topic.”

Working with her mentor, Lisa Shen, MD, associate medical director of pediatric dermatology at Boston University, Ms. Sanchez and colleagues retrospectively reviewed the medical records of 303 patients aged 4-18 years who were diagnosed with HS at Boston Medical Center from 2012 to 2021. Boston Medical Center is the largest safety net hospital in New England. All data points and outcome measures were collected within 6 months of the patient’s HS diagnosis date.

Of the 303 patients with HS, 84% were female and 16% were male. Complete information about race was available in 286 patients. Of these, 65% were Black/African American, 11% were White, and the rest were from other racial groups. The mean age at symptom onset was 13 years, while the mean age at diagnosis was 15 years, and the mean delay to diagnosis was 2 years. A family history of HS was reported in 36% of patients.

The most common clinical features in these HS patients were pain/tenderness (90%), pustules/papules (65%), discharge/drainage (62%), and deep-seated nodules (51%). Scarring was present in 44% of patients at the time of diagnosis. The three most common sites of involvement were the axillary area (79%), the pubic area (36%), and the inguinal folds/inner thighs (34%).

Obesity was the most common comorbidity at the time of diagnosis, with 64% of patients affected. The next most common comorbidities were acne vulgaris (36%), acanthosis nigricans (25%), depression (18%), being overweight (17%), polycystic ovary syndrome (16%) and anxiety (13%). None had type 1 diabetes or metabolic syndrome.

Referring to the large population of underserved minority patients at Boston Medical Center, Dr. Shen noted, “we have to make sure not to underestimate the prevalence of obesity in this population as they get older. We need to start from a younger age to incorporate multidisciplinary care such as weight management, nutrition, and working with our pediatric surgery colleagues in trying to tackle [HS] because there is data to suggest that the earlier we intervene, the better outcomes they have. That makes sense.”

Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, who was asked to comment on the findings, said that the study “highlights the impressive and concerning gap and delays in diagnosis, not too dissimilar to what the literature shows in adult HS patients, which unfortunately has tremendous ramifications, both physically and emotionally/psychosocially.”

While this single-center study identified potential risk factors, such as obesity and self-identifying as Black, he said, “it is important to note that this condition does not discriminate and therefore it is important not to miss the cases that don’t follow the textbook nor stigmatize this condition as one that only impacts certain demographics.”

The researchers reported having no financial disclosures. Dr. Friedman, who was not involved with the study, reported that he serves as a consultant and/or advisor to numerous pharmaceutical companies. He is a speaker for companies including, Regeneron, Sanofi, AbbVie, Janssen, Incyte, and Brickell Biotech, and has received grants from Pfizer, the Dermatology Foundation, Almirall, Incyte, Galderma, and Janssen.
