It is all about who you know: Social capital and health in low-income communities

There is an increasing understanding about the importance of social networks in the overall health of individuals. In the past year studies have found that strong social ties could promote brain health as we age; having obese friends increases the risk for obesity; and older people with many friends outlive those with fewer friends. This manuscript describes capacity-building interventions based on social capital, including empowerment, community youth development and collective efficacy models, which can work at the individual and community level in preventive and treatment-based interventions. These interventions allow public health practitioners working with low-income communities to reduce health disparities, promote well-being, and decrease inequalities.
