The World Health Organization (WHO) issued its first global guidelines addressing the integrated management of obesity in children and adolescents. The guidance strongly recommends structured interventions that include healthy nutrition, physical activity and behavior-change strategies, delivered either individually or through a comprehensive multimodal program. Digital health interventions may also be used, provided they include appropriate parent or caregiver involvement (conditional recommendation). For children younger than 10 years of age, the WHO does not recommend pharmacotherapy, bariatric surgery or weight-loss devices. For adolescents 10–19 years of age, use of pharmacotherapy is considered only when intensive lifestyle interventions have not achieved adequate results. Bariatric surgery should be reserved for adolescents with severe obesity and considered only under carefully defined clinical circumstances. 

A retrospective cross-sectional study published in Pediatrics evaluated trends in glucagon-like peptide-1 receptor agonist (GLP-1 RA) prescribing among children 8–11 years of age with obesity and without diabetes using a large United States (U.S.) electronic health record database that included more than 3.5 million children. Data were sourced from the Epic Cosmos Data Science Virtual Machine and analyzed in the form of repeated annual cohorts. The analysis included prescriptions for the GLP-1 RAs liraglutide (Saxenda), semaglutide (Wegovy) and tirzepatide (Zepbound). Obesity was defined as a body mass index (BMI) at or above the 95th percentile for age and sex according to the Centers for Disease Control and Prevention (CDC) 2000 Growth Charts. The investigators found that GLP-1 RA prescribing increased dramatically between 2019 and 2026. By 2026, 9.3% of children in the study population had received a GLP-1 RA prescription, compared with 0.03% in 2019, demonstrating a 310-fold increase (P<0.001). Prescribing was more common among older children, females, children with lower social vulnerability, children with severe obesity and those with obesity-related comorbidities. The most frequently prescribed initial GLP-1 RA was semaglutide (Wegovy). The authors noted that, although overall use across the entire study period remained low (0.6%), the rapid growth in prescribing suggests increasing off-label use of GLP-1 RAs in younger children. Wegovy and Saxenda are the only FDA-approved GLP-1 RAs for children and adolescents 12–17 years of age for weight management. Additional evidence regarding the safety, effectiveness and appropriate role of these agents in this age group is warranted. 

A retrospective claims analysis published in Childhood Obesity evaluated nutritional deficiencies and nutrition therapy/counseling (NT/C) in pediatric patients receiving GLP-1 RAs. From an initial Inovalon Insights Claims Database population of over 109 million individuals, 2,031 pediatric patients 10–17 years of age who initiated a GLP-1 RA between January 1, 2017, and December 31, 2022, were included in the analysis. Patients with type 1 diabetes mellitus (T1DM) or diagnoses related to nutritional deficiency or associated complications in the six months prior were excluded. GLP-1 RAs initiated during the study period included dulaglutide, exenatide, liraglutide, lixisenatide and semaglutide (tirzepatide was not FDA-approved during the study period). Patients in the identified cohort (n=2,031) had a mean age of 15 years, and the majority were female (61.5%) and had obesity (62.6%) and/or type 2 diabetes mellitus (T2DM; 67.2%). The most prescribed GLP-1 RA was liraglutide (78.6%), followed by dulaglutide (10.4%) and semaglutide (9.1%). Patients were identified as having a nutritional deficiency based on the International Classification of Diseases, 10th edition (ICD-10) codes for up to one year following GLP-1 RA initiation. Nearly 17% of patients were diagnosed with at least one nutritional deficiency or deficiency-related complication within one year of GLP-1 RA initiation. Vitamin D deficiency (12.4%) was the most frequently diagnosed, followed by nutritional anemia (1.55%) and iron-deficiency anemia (1.44%). Despite these risks, nutrition therapy and counseling were infrequently used, with only 23.3% of patients receiving an NT/C visit within six months of GLP-1 RA dispensing; the mean time to the first NT/C visit was 149 days following GLP-1 RA initiation.
