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.

Detailed description

The Louisiana-based, 12-week, multi-level, multi-component, ecological intervention is called Preventing Obesity Using Digital-assisted Movement and Eating (ProudMe). Guided by robust theories and prior work, this project involves multiple trained student researchers to address two specific aims. Aim 1: to test the effectiveness of the ProudMe intervention in Louisiana middle schools. Informed by power analysis (80% statistical power), the study recruits 480 adolescents from 12 middle schools (cluster-randomized to 6 ProudMe schools vs 6 wait-list control schools). Quantitative data on obesity-prevention behaviors (i.e., physical activity, screen-based sedentary behavior, diet behaviors) and weight status (i.e., body mass index z score, waist circumference) are collected from all adolescent participants using validated instruments and procedures. The investigators hypothesize the multi-level modeling analyses to show improvements of obesity-prevention behaviors and weight status in the ProudMe group compared to a waist-list control, after controlling for sociodemographic factors at multiple ecological levels. Aim 2: to test the implementation outcomes of the ProudMe intervention in Louisiana middle schools. The investigators collect mixed-methods data from 24 school implementers (i.e., teachers, administrators, and staff), 96 adolescents, and 96 parents at the 6 ProudMe schools, to capture adaptation and implementation indicators. The investigators evaluate the adaptations made across three phases (early, mid, late) of the implementation (i.e., what, at what level, when, how, why, by whom, and impact to intervention). In addition, the investigators assess reach, fidelity, penetration, sustainability, and cost of the implementation across early, mid, and late phases of the implementation. The investigators expect the ProudMe schools to show appropriate levels of adaptation, fidelity, reach, penetration, and sustainability, with manageable time and financial cost. Building on previously funded work (e.g., R21HD090513, PI: Dr. Chen), this project is led by a strong, collaborative, transdisciplinary team with experts from kinesiology, developmental psychology, nutrition, childhood obesity, computer science, statistics, and implementation science. The project significantly strengthens the research environment of the Louisiana State University (LSU) - a primarily undergraduate student serving institution under-funded by the NIH. The project creates unique opportunities that are otherwise unavailable for LSU students who aspire to seek advanced education or careers in biomedical and health fields.

Conditions

• Treatment (ProudMe)
• Waitlist Control

Interventions

Type	Name	Description
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. ProudMe Cafeteria: Purposely enabling policy and environmental changes in school cafeteria (recognize areas of strengths and weaknesses; set goals and action plans; make changes to improve scores assessed by the Smarter Lunchroom Scorecard). ProudMe Training: 4-hour implementation training + regular check-in and support (via motivational interviewing techniques)
BEHAVIORAL	Waitlist Control	The waitlist control involves (a) regular physical/health education and lunchroom, (b) professional development training on the overall importance of quality physical/health education, health eating and foot environment. It does not involve AI-assisted behavior management system.
