Design of a randomized controlled trial to decrease depression and improve insulin sensitivity in adolescents: Mood...

Area of Science:

• Endocrinology
• Metabolic Health
• Adolescent Health

Background:

• Depressive symptoms in adolescence are linked to reduced insulin sensitivity.
• This can accelerate the progression to beta-cell failure and type 2 diabetes (T2D).

Purpose of the Study:

• To evaluate a cognitive-behavioral group intervention versus health education for improving insulin sensitivity and beta-cell function.
• To explore mechanisms linking depression to insulin dynamics in at-risk adolescent girls.

Main Methods:

• A randomized controlled trial involving 150 adolescent girls (12-17 years) with overweight/obesity and depressive symptoms.
• Interventions included a six-week cognitive-behavioral group or a health education control group.
• Assessments at baseline, post-intervention, and one-year follow-up measured insulin sensitivity, beta-cell function, and other metabolic/psychological factors.

Main Results:

• The study aims to determine if reducing depressive symptoms via behavioral health programs can preventatively alter insulin sensitivity and beta-cell function.
• Results will elucidate the role of depressive symptoms in T2D risk among adolescents.

Conclusions:

• Findings will inform the potential of behavioral interventions in T2D prevention for at-risk youth.
• This research contributes to understanding the complex interplay between mental health and metabolic disease progression.
