Healthier Lifestyles for Teens with Type 1 Diabetes
Official title: Adapting an Adolescent Weight Management Program for a Type 1 Diabetes Population
Run by The Miriam Hospital · NCT06878872 · Data updated 2026-11-12
We will try a tailored lifestyle program (T1DAL) to help teens with type 1 diabetes who are overweight or at risk of obesity improve their health and reduce risk of disordered eating.

Is this trial a fit for you?
✓Likely a good fit
Adolescents with type 1 diabetes diagnosed at least six months earlier who have a BMI at or above the 70th percentile for age and sex, live with a parent/caregiver, have a smartphone, and speak and read English.
✕Probably not a fit
Those unlikely to benefit include teens with medical limits on group or physical activity, current psychosis or suicidality, recent major weight loss, current enrollment in another intensive lifestyle program, pregnancy or planned pregnancy, unwillingness to wear a continuous glucose monitor, or use of medications that affect weight or appetite.

What this trial studies
This interventional study tests the T1DAL program, an adapted intensive health behavior and lifestyle treatment designed specifically for adolescents with type 1 diabetes. About 50 adolescents who meet eligibility criteria will be enrolled and compared with a usual care control group to measure preliminary effects on weight-related health, glycemic outcomes, and eating disorder risk. The program includes diabetes-specific adaptations such as guidance for managing hypoglycemia around meals and exercise, attention to healthier food choices, and caregiver involvement, and uses smartphone-enabled components and continuous glucose monitor assessments. Outcomes will inform feasibility and whether a larger trial is warranted.
Why it matters
Potential benefit: If successful, the program could help teens with T1D reduce excess weight, improve metabolic and cardiovascular risk factors, and lower the likelihood of developing disordered eating behaviors.
How similar studies have gone: Intensive lifestyle treatments are proven effective for pediatric obesity, but programs specifically adapted and tested for adolescents with type 1 diabetes and built-in eating disorder prevention remain relatively novel.
