Summary

This study tested whether adding peer support and online education helps college students manage their weight and improve their mood. Researchers enrolled 216 full-time students aged 18-25 with a BMI of 24 or higher and randomly assigned them to one of three groups: standard health education alone, standard education plus peer mentor meetings and an online chat group, or standard education plus a custom app with lessons, expert Q&A, and self-tracking. Weight, BMI, depression, anxiety, and life satisfaction were measured over six months to see which approach works best.
