ABSTRACT
BACKGROUND: Recent pediatric guidelines recommend clinicians offer anti-obesity medication (AOM) as an adjunct to intensive lifestyle intervention. OBJECTIVE: To investigate pediatricians' perspectives about prescribing AOM, including barriers and facilitators. METHODS: An investigator-developed survey was emailed to primary care pediatric physicians (n = 187) and advanced practice providers (n = 190) within an academic-affiliated network. The survey evaluated how willing clinicians were to prescribe AOM and their agreement with 25 statements about barriers and facilitators. Three vignettes explored AOM decision-making. Multinomial logistic regression was used to determine relative risk ratios for willingness to prescribe by agreement with each statement. RESULTS: Among 74 respondents (20% response rate), 24% were willing, 42% uncertain and 34% unwilling to prescribe. Most (64%) agreed that AOM should be managed only by specialists. Willingness to prescribe was associated with clinician motivation and belief in guideline practicality and applicability. Unwillingness was associated with beliefs that patients would not continue AOM long enough for benefit and that there was insufficient time or resources to implement. In vignettes, 52% were willing to prescribe AOM for a patient with severe obesity and metabolic complications, versus 11% for a patient with obesity and possible disordered eating. CONCLUSIONS: Willingness to prescribe AOM was low and was associated with perceived practicality and appropriateness for patients.

Importance: Adolescent severe obesity is usually not effectively treated with traditional lifestyle modification therapy. Meal replacement therapy (MRT) shows short-term efficacy for body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) reduction in adolescents, and financial incentives (FIs) may be an appropriate adjunct intervention to enhance long-term efficacy. Objective: To evaluate the effect of MRT plus FIs vs MRT alone on BMI, body fat, and cardiometabolic risk factors in adolescents with severe obesity. Design, Setting, and Participants: This was a randomized clinical trial of MRT plus FIs vs MRT alone at a large academic health center in the Midwest conducted from 2018 to 2022. Participants were adolescents (ages 13-17 y) with severe obesity (≥120% of the 95th BMI percentile based on sex and age or ≥35 BMI, whichever was lower) who were unaware of the FI component of the trial until they were randomized to MRT plus FIs or until the end of the trial. Study staff members collecting clinical measures were blinded to treatment condition. Data were analyzed from March 2022 to February 2024. Interventions: MRT included provision of preportioned, calorie-controlled meals (~1200 kcals/d). In the MRT plus FI group, incentives were provided based on reduction in body weight from baseline. Main Outcomes and Measures: The primary end point was mean BMI percentage change from randomization to 52 weeks. Secondary end points included total body fat and cardiometabolic risk factors: blood pressure, triglyceride to high-density lipoprotein ratio, heart rate variability, and arterial stiffness. Cost-effectiveness was additionally evaluated. Safety was assessed through monthly adverse event monitoring and frequent assessment of unhealthy weight-control behaviors. Results: Among 126 adolescents with severe obesity (73 female [57.9%]; mean [SD] age, 15.3 [1.2] years), 63 participants received MRT plus FIs and 63 participants received only MRT. At 52 weeks, the mean BMI reduction was greater by -5.9 percentage points (95% CI, -9.9 to -1.9 percentage points; P = .004) in the MRT plus FI compared with the MRT group. The MRT plus FI group had a greater reduction in mean total body fat mass by -4.8 kg (95% CI, -9.1 to -0.6 kg; P = .03) and was cost-effective (incremental cost-effectiveness ratio, $39â¯178 per quality-adjusted life year) compared with MRT alone. There were no significant differences in cardiometabolic risk factors or unhealthy weight-control behaviors between groups. Conclusions and Relevance: In this study, adding FIs to MRT resulted in greater reductions in BMI and total body fat in adolescents with severe obesity without increased unhealthy weight-control behaviors. FIs were cost-effective and possibly promoted adherence to health behaviors. Trial Registration: ClinicalTrials.gov Identifier: NCT03137433.

PURPOSE OF REVIEW: The purpose of this review is to describe the existing limited data related to the use of semaglutide in adolescents with obesity, supplementing with findings from adult studies of semaglutide use. RECENT FINDINGS: Semaglutide, as a once weekly subcutaneous injection for weight management, effectively reduces body mass index (BMI) while improving hyperglycemia, elevated alanine aminotransferase levels, hyperlipidemia, and quality of life in youth with obesity. As of this review, only one large randomized clinical trial of semaglutide in youth has been completed, with a follow-up duration of 68âweeks. Thus, long-term data on the safety in adolescents is limited, particularly regarding the risks of cholelithiasis, pancreatitis, suicidal ideation, and disordered eating. Due to the cost of semaglutide, particularly in the United States, limited cost effectiveness analyses have demonstrated unfavorable incremental cost-effectiveness ratios for semaglutide relative to phentermine-topiramate as an alternative antiobesity medication in adolescents. SUMMARY: Semaglutide represents an important advance in the pediatric obesity management, with clear short-term reductions in BMI and improvement in metabolic parameters. However, its long-term safety and efficacy for youth with obesity remain to be demonstrated. Additional research is needed to assess trends in utilization and adherence to minimize the risk of worsening socioeconomic disparities in pediatric obesity.

INTRODUCTION: Whilst glucagon-like peptide-1 receptor agonists (GLP1-RAs) are effective for treating adolescent obesity, weight loss maintenance (WLM; preventing weight regain) remains a challenge. Our goal was to investigate appetite/satiety hormones and eating behaviours that may predict WLM with exenatide (a GLP1-RA) versus placebo in adolescents with severe obesity. METHODS: Adolescents who had ≥5% body mass index (BMI) reduction with meal replacement therapy were randomized to 52 weeks of once-weekly exenatide extended release or placebo. In this secondary analysis, eating behaviours and appetite/satiety regulation hormones post-meal replacement therapy (pre-randomization to exenatide or placebo) were evaluated as possible predictors of WLM. Percent change in BMI from randomization to 52 weeks served as the primary measure of WLM. RESULTS: The analysis included 66 adolescents (mean age 16.0 years; 47% female). Lower leptin response to meal testing was associated with greater WLM in terms of BMI percent change in those receiving exenatide compared to placebo (p = 0.007) after adjusting for sex, age and BMI. There were no other significant predictors of WLM. CONCLUSIONS: Prior to exenatide, lower leptin response to meals was associated with improved WLM with exenatide compared to placebo. The mostly null findings of this study suggest that GLP1-RA treatment may produce similar WLM for adolescents with obesity regardless of age, BMI, sex and eating behaviours.

This cross-sectional analysis of the Minnesota Now Everybody Together for Amazing Healthful Kids (NET-Works) study evaluated whether SNAP participation was associated with specific parental feeding styles and child eating behaviors. Associations between parent-reported feeding styles and child eating behaviors and SNAP participation were examined using multiple linear regression analyses and responses from 534 parent/child dyads (49.1% female children, 91.7% female parents). SNAP participation was not associated with specific feeding styles or child eating behaviors when adjusting for food insecurity, timing in SNAP cycle, and other covariates in this large, ethnically and racially diverse sample of predominantly mothers and preschool-aged children. Other factors, such as food insecurity, not SNAP participation, may influence parental feeding and child eating behaviors, and screening by health care providers is recommended.
ABSTRACT
BACKGROUND: Severe obesity is a complex, chronic disease affecting nearly 9% of adolescents in the U.S. Although the current mainstay of treatment is lifestyle therapy, pediatric clinical practice guidelines recommend the addition of adjunct anti-obesity medication (AOM), such as phentermine and topiramate. However, guidance regarding when adjunct AOM should be started and how AOM should be used is unclear. Furthermore, an inherent limitation of current treatment guidelines is their "one-size-fits-all" approach, which does not account for the heterogeneous nature of obesity and high degree of patient variability in response to all interventions. METHODS: This paper describes the study design and methods of a sequential multiple assignment randomized trial (SMART), "SMART Use of Medications for the Treatment of Adolescent Severe Obesity." The trial will examine 1) when to start AOM (specifically phentermine) in adolescents who are not responding to lifestyle therapy and 2) how to modify AOM when there is a sub-optimal response to the initial pharmacological intervention (specifically, for phentermine non-responders, is it better to add topiramate to phentermine or switch to topiramate monotherapy). Critically, participant characteristics that may differentially affect response to treatment will be assessed and evaluated as potential moderators of intervention efficacy. CONCLUSION: Data from this study will be used to inform the development of an adaptive intervention for the treatment of adolescent severe obesity that includes empirically-derived decision rules regarding when and how to use AOM. Future research will test this adaptive intervention against standard "one-size-fits-all" treatments.

Obesity is a multifactorial chronic disease for which treatment remains challenging. While the cornerstone treatment is lifestyle modification, the addition of anti-obesity medications leads to greater weight reduction. In cases where monotherapy with a single anti-obesity medication results in either weight stabilization or only modest weight reduction, combination regimens can be highly effective, especially those including glucagon-like peptide-1 receptor agonists. We report the case of a 23-year-old male initially presenting with a body mass index of 84.3â kg/m2. In addition to lifestyle modification therapy, he was started on phentermine, topiramate, and metformin, which only resulted in weight stabilization after 1 year. Subsequently, semaglutide (a glucagon-like peptide-1 receptor agonist) was added, along with a lower calorie diet, which resulted in a 32.5% total body weight reduction, approximating that which can be achieved following metabolic/bariatric surgery. This case highlights the potential benefit of combination anti-obesity medication regimens including glucagon-like peptide-1 receptor agonists, as such regimens may provide a synergistic effect by targeting multiple eating behavior pathways simultaneously. Further studies are needed to evaluate the efficacy of combination anti-obesity medication regimens, especially among those achieving suboptimal response to monotherapies.

BACKGROUND: As childhood obesity prevalence increases, determining which patients respond to anti-obesity medications would strengthen personalized approaches to obesity treatment. In the SCALE Teens trial among pubertal adolescents with obesity (NCT02918279), liraglutide 3.0 mg (or maximum tolerated dose) significantly reduced body mass index (BMI) standard deviation score on average versus placebo. That said, liraglutide effects on BMI reduction varied greatly among adolescents, similar to adults. OBJECTIVES: To identify post hoc characteristics predictive of achieving ≥5% and ≥10% BMI reductions at 56 weeks with liraglutide versus placebo in adolescents from the SCALE Teens trial. METHODS: Logistic regression analysis was performed in 251 adolescents treated with liraglutide (n = 125) or placebo (n = 126) for 56 weeks. Baseline characteristics (selected a priori) included sex, race, ethnicity, age, Tanner (pubertal) stage, glycemic status (hyperglycemia [type 2 diabetes/prediabetes] vs. normoglycemia), obesity category (Class II/III vs. I), severity of depression symptoms (Patient Health Questionnaire-9), and weight variability (weight fluctuations over time). The effects of early responder status (≥4% BMI reduction at week 16) on week 56 response were assessed using descriptive statistics. RESULTS: Baseline characteristics did not affect achievement of ≥5% and ≥10% BMI reductions at week 56 in adolescents treated with liraglutide. Further, there was no association between weight variability and BMI reduction. Early liraglutide responders appeared to have greater BMI and body weight reductions at week 56 compared with early non-responders. CONCLUSIONS: This secondary analysis suggests that adolescents with obesity may experience significant BMI reductions after 56 weeks of liraglutide treatment, regardless of their sex, race, ethnicity, age, pubertal stage, glycemic status, obesity category, severity of depression symptoms, or weight variability. Early response may predict greater week 56 response.

Type 2 diabetes mellitus (T2DM) in adolescents is a more rapidly progressive disease, associated with earlier and higher rates of microvascular complications than in adults. As obesity is a significant risk factor for T2DM development and progression, the American Diabetes Association (ADA) recommends anti-obesity medications (AOMs) as adjuvant therapy for adults with both T2DM and overweight/obesity. In adults, the addition of AOMs to a diabetes regimen can improve glycemic control, reduce weight, and decrease anti-diabetes medication use. The ADA recommends considering bariatric surgery for adolescents with T2DM who have a BMI >35 kg/m2, but did not mention the use of AOMs in their 2022 updated guidelines. Currently, there are three FDA-approved AOMs available for chronic use in adolescents with obesity. Other medications are used in an "off-label" fashion for appetite suppression and BMI reduction. As additional AOMs are being developed and FDA-approved for the pediatric population, new treatment options with novel mechanisms of action will become available for adolescents with T2DM and obesity. In this review, we will discuss the evidence for the use of AOMs in the treatment of T2DM in adolescents, including lessons learned from the adult T2DM literature.

OBJECTIVE: This study sought to evaluate the effect of 52 weeks of exenatide extended release (XR) on the maintenance of meal replacement therapy (MRT)-induced BMI reduction in adolescents with severe obesity. METHODS: In this randomized, double-blind, placebo-controlled trial, 100 participants aged 12 to 18 years with BMI ≥ 1.2 × 95th percentile were enrolled in a short-term MRT run-in phase. Those who achieved ≥5% BMI reduction during the run-in were then randomized to 52 weeks of exenatide XR 2.0 mg or placebo weekly. Both groups also received lifestyle therapy. The prespecified primary end point was mean percent change in BMI from randomization (post run-in) to 52 weeks in the intention-to-treat population. RESULTS: A total of 100 participants were enrolled, and 66 (mean age 16 = [SD 1.5] years; 47% female) achieved ≥5% BMI reduction with MRT and were randomized (33 to exenatide XR and 33 to placebo). From randomization (post run-in) to 52 weeks, mean BMI increased 4.6% and 10.1% in the exenatide XR and placebo groups, respectively. The placebo-subtracted exenatide XR treatment effect was -4.1% (95% CI: -8.6% to 0.5%, p = 0.078). CONCLUSIONS: Although not achieving statistical significance, exenatide XR, compared with placebo, may partly mitigate the propensity toward BMI rebound in adolescents who achieved initial weight loss with dietary intervention.

BACKGROUND: Antiobesity medication may be useful for the treatment of pediatric obesity, yet few safe and effective options exist. We evaluated phentermine/topiramate (PHEN/TPM) for weight management in adolescents with obesity. METHODS: This 56-week, randomized, double-blind trial enrolled adolescents 12 to less than 17 years of age with obesity. Participants were randomly assigned 1:1:2 to receive either placebo (n=56), mid-dose PHEN/TPM (7.5 mg/46 mg; n=54), or top-dose PHEN/TPM (15 mg/92 mg; n=113), respectively. All participants received lifestyle therapy. The primary end point was mean percent change in body-mass index (BMI) from randomization to week 56. RESULTS: Participants had a mean (±SD) age of 14.0±1.4 years and a mean (±SD) BMI of 37.8±7.1 kg/m2; 54.3% were female. The primary end point of percent change in BMI at week 56 showed differences from placebo of -10.44 percentage points (95% CI, -13.89 to -6.99; P<0.001) and -8.11 percentage points (95% CI, -11.92 to -4.31; P<0.001) for the top and mid doses of PHEN/TPM, respectively. Differences from placebo in percent change in triglycerides nominally favored PHEN/TPM (mid dose, -21%; 95% CI, -40 to -2; and top dose, -21%; 95% CI, -38 to -4), as did differences in percent change in high-density lipoprotein cholesterol (HDL-C) (mid dose, 10%; 95% CI, 3 to 18; and top dose, 9%; 95% CI, 2 to 15). The incidence of participants reporting at least one adverse event was 51.8%, 37.0%, and 52.2% in the placebo, mid-dose, and top-dose groups, respectively. Serious adverse events were reported for two participants in the top-dose group. CONCLUSIONS: PHEN/TPM at both the mid and top doses offered a statistically significant reduction in BMI and favorably impacted triglyceride and HDL-C levels in adolescents with obesity.

ABSTRACT
BACKGROUND: There are limited data comparing the relative associations of various BMI metrics with adiposity and cardiometabolic risk factors in youth. OBJECTIVE: Examine correlations of 7 different BMI metrics with adiposity, cardiometabolic risk factors, and biomarkers (i.e. blood pressure, waist circumference, cholesterol, leptin, insulin, high molecular weight adiponectin, high-sensitivity c-reactive protein (hsCRP)). METHODS: This was a cross-sectional analysis of youth in all BMI categories. BMI metrics: BMI z-score (BMIz), extended BMIz (ext.BMIz), BMI percentile (BMIp), percent of the BMI 95th percentile (%BMIp95), percent of the BMI median (%BMIp50), triponderal mass index (TMI), and BMI (BMI). Correlations between these BMI metrics and adiposity, visceral adiposity, cardiometabolic risk factors and biomarkers were summarized using Pearson's correlations. RESULTS: Data from 371 children and adolescents ages 8-21 years old were included in our analysis: 52% were female; 20.2% with Class I obesity, 20.5% with Class II, and 14.3% with Class III obesity. BMIp consistently demonstrated lower correlations with adiposity, risk factors, and biomarkers (r = 0.190-0.768) than other BMI metrics. The %BMIp95 and %BMIp50 were marginally more strongly correlated with measures of adiposity as compared to other BMI metrics. The ext.BMIz did not meaningfully outperform BMIz. CONCLUSION: Out of all the BMI metrics evaluated, %BMIp95 and %BMIp50 were the most strongly correlated with measures of adiposity. %BMIp95 has the benefit of being used currently to define obesity and severe obesity in both clinical and research settings. BMIp consistently had the lowest correlations. Future research should evaluate the longitudinal stability of various BMI metrics and their relative associations with medium to long-term changes in adiposity and cardiometabolic outcomes in the context of intervention trials.

Background: Studies examining the association between hedonic hunger, that is, having frequent thoughts about food in the absence of an energy deficit, and obesity in youth show mixed results. This may be due to the confounding effect of binge eating, which has been associated with both hedonic hunger and obesity. The purpose of this study was to determine the extent to which hedonic hunger is associated with obesity independent of binge eating in youth. Methods: Data for this cross-sectional study were collected from youth enrolled in a larger study of cardiovascular disease and obesity. Linear regression models were used to assess the association between hedonic hunger measured by Power of Food Scale (PFS) and binge eating measured by Eating Disorder Examination-Questionnaire, on percent of the 95th BMI percentile (BMIp95). Results: Among 269 participants (mean age 12.8 years), 16.4% endorsed binge eating. PFS was positively associated with BMIp95 with a difference in percent of BMIp95 of 5.9% [95% confidence interval (1.5-10.3), p = 0.009]. However, when binge eating was added to the model, the relationship between PFS and BMIp95 was no longer significant. Conclusion: Hedonic hunger, above and beyond binge eating, may not be associated with BMI. Future research should examine whether screening for and targeting binge eating rather than hedonic hunger in weight management care may have more impact on obesity outcomes.

BACKGROUND: The Child and Adult Eating Behavior Questionnaires (CEBQ, AEBQ) are established measures of eating behaviors. However, no similar measure is available for adolescents. Prior research has validated the AEBQ in adult samples, and one study has explored using the measure with adolescents. However, no studies to date have examined the validity of the AEBQ in adolescent clinical populations. Furthermore, no studies have examined associations between the AEBQ and indicators of health status in adolescents. METHODS: A total of 280 adolescents (12-17 years old, 60% female) seen in a pediatric weight management clinic completed the AEBQ at intake. Confirmatory factor analysis (CFA) was conducted with AEBQ items to evaluate the model fit of one-, two-, seven-, and eight-factor structures. Intercorrelations between scale scores from AEBQ Food Approach and Food Avoidance domains were calculated. Associations of AEBQ scales with body mass index (BMI) and binge-eating behaviors were examined using Spearman Rho correlations and independent t-tests. RESULTS: CFAs revealed that the best fitting model was a seven-factor structure excluding the Hunger scale, although overall model fit was only marginally acceptable (X2 = 980.94, CFI = 0.925, TLI = 0.915, RMSEA = 0.074). Intercorrelation analyses indicated that all Food Approach scales were significantly associated with one another (r = 0.243-0.654); Food Avoidance scales were inconsistently correlated (r = 0.034-0.439). No AEBQ scales were correlated with BMI (r = -0.101-0.082). Stronger links were found with binge eating; higher frequency binge-related behaviors were associated with higher Food Approach scores. CONCLUSIONS: The seven-factor structure of AEBQ demonstrates a marginally acceptable fit for treatment-seeking adolescents with obesity. The Food Approach scales demonstrated more convergent validity than the Food Avoidance scales. The Food Approach scales also exhibited some clinical utility for identifying patients with increased risk for binge eating, which is a common target for behavioral intervention. Implications for maximizing the AEBQ's potential for assessing eating behaviors in adolescents with obesity are discussed.

BACKGROUND: Weight loss in children and adolescents with type 2 diabetes (T2D) is associated with improved glycaemic control. OBJECTIVES: To assess the effects of liraglutide vs placebo on body mass index (BMI) and weight parameters in children and adolescents with T2D using data from the ellipse trial (NCT01541215). METHODS: The ellipse trial randomized participants (10-<17 years old, BMI >85th percentile, T2D, glycated haemoglobin [HbA1c ] 7.0%-11.0% [if diet- and exercise-treated] or 6.5% to 11.0% [if treated with metformin, basal insulin or both]) to liraglutide or placebo. This post-hoc analysis evaluated changes from baseline to weeks 26 and 52 in absolute BMI, percent change in BMI and other weight-related parameters. Changes were assessed by liraglutide overall (all doses) and liraglutide by dose (0.6, 1.2 and 1.8 mg/day) vs placebo using a pattern mixture model of observed data, with missing observations imputed from each treatment group. RESULTS: In total, 134 participants were included. There were statistically significant differences between groups in certain parameters, including absolute BMI (estimated treatment difference [ETD] -0.89 kg/m2 ; 95% confidence interval [CI] -1.71,-0.06) and percent change in BMI (ETD -2.73%; 95% CI -5.15,-0.30) at week 52, but none at week 26. Dose-dependent effects were not observed for liraglutide vs placebo for all BMI/weight parameters. CONCLUSIONS: Compared with placebo, liraglutide was associated with statistically significant reductions in BMI/weight parameters at week 52, but not week 26, in children and adolescents with T2D.
