Investigators will conduct a 5-community longitudinal study using a cluster randomized stepped-wedge design to evaluate the intervention impact on alcohol, tobacco, and other drug (ATOD) and obesity prevention primary aims of: (1) substance use harm reduction, overall ATOD use and intentions to use; and (2) weight/body mass index (BMI) change as well as the effect on leisure-time physical activity/physical activity (LTPA/PA), and healthful food habits among adult Choctaw women at risk for obesity and ATOD. The cluster randomized stepped-wedge design is a type of cross-over study in which clusters of women from each community cross over to the intervention arm at randomly assigned time points (one time per year, per community).
