Given the high rate of hypertension and obesity in minority and immigrant communities, implementing culturally and linguistically appropriate health promotion activities that improve families' diet and physical activity behaviors is imperative. "Radio Stories" is an education entertainment strategy that has significant potential as a health promotion tool. Through a CBPAR process, we aimed to create and test the effectiveness and acceptability of "SoLaHmo Radio Stories" about changing knowledge and behaviors to prevent or manage hypertension and obesity for Somali, Latino, and Hmong families with children.
