This is a great discussion and has led me to briefly look over some data GLP-1 agonists in pediatric populations.
This
study suggests that they are more effective for weight loss in those with obesity than those with diabetes alone. Makes sense that there would be a HgbA1c drop in those with prediabetes than obesity alone. They say that the effect size is comparable to adults, but these studies don't compare children to adults.
It looks like the
odds for a teen of losing weight with a GLP-1 agonist is HUGE compared to placebo/lifestyle intervention alone. Interesting tidbit about semaglutide being associated with gallstones whereas no one in the placebo group had that.
Some pediatricians would rather prescribe medications than counsel on lifestyle because the majority of pediatrician visits are less than 20 minutes. It's really tough to get everything in during that time, especially for a teen who may already sensitive about body weight. However, I would hope that most would counsel on lifestyle interventions first, just as in mental health where if there is anxiety or depression, I hope they would counsel on lifestyle interventions first if there is no high severity or risk concerns.
