Social Networks and Obesity Among Somali Immigrants and Refugees
BMC Public Health Feb 2020
A community-based participatory research project led by RHCP examined the relationship between social networks and obesity among Somali immigrants and refugees in Rochester, Minnesota. Survey and biometric data from 646 participants revealed that half were overweight or obese, and those with higher BMI tended to have more overweight individuals in their social networks. This clustering was especially pronounced among men and adults aged 50 and older. Participants who intended to lose weight were more likely to report supportive social norms, higher social cohesion, and encouragement from family and friends. Functional network factors—such as social support for healthy eating and norms favoring weight loss—were positively associated with weight loss intentions.
The study found that social networks among Somali immigrants are distinct and influential in shaping health behaviors, particularly around obesity and weight loss. While structural network characteristics like network size did not mediate weight status, functional aspects such as social norms and support played a significant role. These findings suggest that a social network intervention targeting weight loss, grounded in CBPR principles, is feasible and potentially effective for this population. The research highlights the importance of leveraging community ties and culturally relevant strategies to address obesity and promote healthier lifestyles in immigrant communities.
