Dissemination of an Adolescent Obesity Prevention Intervention to Louisiana Schools

Summary

This project aims to test the effectiveness and implementation of an adolescent obesity prevention intervention called ProudMe. The study recruits 480 adolescents from 12 middle schools (cluster-randomized to 6 ProudMe schools vs 6 wait-list control schools) and expect to observe improvements of obesity-prevention behaviors and weight status in the ProudMe group compared to the control. The investigators also collect mixed-methods data from 24 school implementers at the 6 ProudMe schools and expect to observe appropriate levels of adaptation, fidelity, reach, penetration, and sustainability, with manageable time and financial cost.

Conditions

• Treatment (ProudMe)

Interventions

BEHAVIORAL

ProudMe

ProudMe Tech: Regular human/computer interaction (3-5 times per week) to engage in SMART goal-setting, behavior monitoring, and self-reflection as assisted by AI-enabled feedback. ProudMe Physical Education \[PE\]: 12 lessons to acquire knowledge, skill, and dispositions to improve physical activity, diet, screen-based sedentary behaviors.
