Implementation of the OPREVENT2 Multilevel Obesity Program for Native American Adults (P04-175-19)

Objectives Multilevel, multicomponent (MLMC) interventions are a promising strategy to address obesity, yet they are complex to implement with sufficient intensity. We report on the process evaluation of a MLMC to prevent/reduce obesity in Native American (NA) adults.
