ActiveGirls physical activity program for hormone health and diabetes-risk prevention in girls ages 8–12

ActiveGirls: Physical Activity, Hormone Health, and Diabetes Risk in Early Adolescence

NA · Massachusetts General Hospital · NCT07102797

This study will test whether a 6-month ActiveGirls program with coaching and messages helps girls ages 8–12 improve hormone health and lower markers of diabetes risk compared with a lower-intensity, delayed program.

What this trial studies

This is a pilot randomized trial enrolling premenarchal girls ages 8–12 who are at elevated risk for PCOS or insulin resistance. Participants are randomized to a full-intensity intervention with health coaching plus educational texts/emails or a delayed, lower-intensity text-only intervention, with caregiver involvement to support at-home activity. Both groups complete objective measures of body composition, insulin dynamics, reproductive hormones, fitness, and continuous activity monitoring, plus surveys at baseline, 6 months, and 12 months. Baseline and 12-month visits are in person at the MGH Translational and Clinical Research Centers and the 6-month assessment is remote.

Who should consider this trial

Good fit: Girls ages 8–12 who are premenarchal and at increased risk for PCOS or insulin resistance (for example due to BMI ≥85th percentile, maternal PCOS/GDM, premature adrenarche, or being small for gestational age) and who have a caregiver able to participate are ideal candidates.

Not a fit: Girls who are post-menarche, have diagnosed type 1 or type 2 diabetes, other endocrine conditions that affect insulin or androgens, or who are taking medications such as metformin, GLP-1 receptor agonists, insulin, or GnRH agonists are unlikely to benefit from this program.

Why it matters

Potential benefit: If successful, the program could help at-risk girls increase physical activity, improve hormone balance, and reduce early markers of diabetes risk.

How similar studies have performed: Some family-based lifestyle and physical activity programs have improved weight and metabolic markers in youth, but interventions specifically targeting peripubertal prevention of PCOS and insulin resistance are limited and this pilot is relatively novel.
