Healthy Immigrant Community Study Protocol: A Randomized Controlled Trial of a Social Network Intervention for Cardiovascular Risk Reduction Among Hispanic and Somali Adults
Contemporary Clinical Field Trials Feb 2024
The Healthy Immigrant Community (HIC) project is a community-driven health initiative developed by RHCP to reduce cardiovascular risks among Hispanic and Somali adults in Minnesota. The program uses a social network approach, where trained health promoters from each community lead group sessions focused on improving diet, physical activity, and overall wellness. These sessions include goal setting, food and activity tracking, and culturally tailored education. Participants are recruited through trusted social connections, and the intervention is delivered in two phases: an initial six-month program followed by a six-month maintenance phase. The study uses a stepped wedge randomized design to compare outcomes like BMI, blood pressure, cholesterol, and glucose levels across time.
The project builds on years of collaboration and research within immigrant communities, recognizing that social ties and cultural relevance are key to promoting lasting health changes. Early results show strong engagement, with 475 participants enrolled and a majority classified as obese at baseline. The intervention is designed to be flexible, scalable, and sustainable, leveraging peer support and community resources. While challenges like treatment fidelity and indirect influence on control groups exist, the approach offers a promising model for addressing health disparities through culturally grounded, community-led strategies.
