A midpoint process evaluation of the Los Angeles Basin Racial and Ethnic Approaches to Community Health Across the US (REACH US) Disparities Center, 2007-2009.

BackgroundRacial/ethnic minority groups have higher risks for disease resulting from obesity.Community contextThe University of California, Los Angeles, and the Los Angeles County Department of Public Health partnered with community organizations to disseminate culturally targeted physical activity and nutrition-based interventions in worksites.MethodsWe conducted community dialogues with people from 59 government and nonprofit health and social service agencies to develop wellness strategies for implementation in worksites. Strategies included structured group exercise breaks and serving healthy refreshments at organizational functions. During the first 2 years, we subcontracted with 6 community-based organizations (primary partners) who disseminated these wellness strategies to 29 organizations within their own professional networks (secondary worksites) through peer modeling and social support. We analyzed data from the first 2 years of the project to evaluate our dissemination approach.OutcomePrimary partners had difficulty recruiting organizations in their professional network as secondary partners to adopt wellness strategies. Within their own organizations, primary partners reported significant increases in implementation in 2 of the 6 core organizational strategies for promoting physical activity and healthy eating. Twelve secondary worksites that completed organizational assessments on 2 occasions reported significant increases in implementation in 4 of the 6 core organizational strategies.InterpretationDissemination of organizational wellness strategies by trained community organizations through their existing networks (train-the-trainer) was only marginally successful. Therefore, we discontinued this dissemination approach and focused on recruiting leaders of organizational networks
