A recent study published in Childhood Obesity has revealed that nearly one in six children (16.8%) who take GLP-1 receptor agonists for weight loss, prediabetes, or type 2 diabetes develop a diagnosed nutritional deficiency within a year of starting treatment. These medications, which mimic a hormone involved in regulating appetite and blood sugar, are increasingly used in pediatric care. The most common deficiency identified in the study was vitamin D, which affected 12.4% of the children within one year of beginning GLP-1 therapy. The research was conducted by scientists at Ann & Robert H. Lurie Children's Hospital of Chicago. It analyzed data from over 100 million patients across the U.S., collected between 2017 and 2022. From this data, the researchers identified 2,031 children aged 10 to 17 who were taking GLP-1 medications and had not previously been diagnosed with a nutritional deficiency. These children met specific criteria, including continuous enrollment in healthcare coverage, to ensure the study's accuracy. Among the GLP-1 medications used by the children, liraglutide (marketed as Victoza and Saxenda) was the most commonly prescribed, making up 78.6% of the prescriptions. Dulaglutide (Trulicity) and semaglutide (Ozempic and Wegovy) were also used, accounting for 10.4% and 9.1% of prescriptions, respectively. The study highlights the need for close attention to nutrition during treatment, as GLP-1 medications can influence appetite and food consumption, potentially leading to deficiencies if not managed properly. Researchers found that only 5% of the children received nutritional counseling within 30 days of starting GLP-1 therapy, and less than 25% received such counseling within six months. The findings suggest that nutritional support should be initiated alongside GLP-1 treatment rather than waiting for a deficiency to be detected. This proactive approach may help prevent health complications and ensure that children receiving these medications continue to get the essential nutrients they need for proper growth and development.
