Mediators and moderators of the effectiveness of a community health worker intervention that improved dietary outcomes in pregnant Latina women

摘要

BackgroundPregnancy is an opportune time to initiate diabetes prevention strategies for minority and underserved women, using culturally tailored interventions delivered by community health workers (CHWs). A community-partnered randomized controlled trial (RCT) with pregnant Latina women resulted in significantly improved vegetable, fiber, added sugar, and total fat consumption compared to a minimal intervention (MI) group. However, studying RCT intervention effects alone does not explain the mechanisms by which the intervention was successful or help identify which participants may have benefitted most.
