This community-based, qualitative study explored social capital resources and their influences upon HIV risk behaviors in a sample of 17 heterosexual Asian Indian immigrant men residing in New York City. Our study defined social capital as the resources available to individuals and society through social relationships. At the family, peer, and community levels, social capital's influence appeared to reduce acculturative stress and HIV risks. However, participants who lacked sexually transmitted infection and HIV transmission knowledge and/or sought peer solidarity through adherence to negative peer norms (e.g., alcohol use with sex) had elevated sexual risks for HIV. These findings suggest the promise of a social capital approach in the development of HIV prevention programs, as well as the need for HIV risk and social capital researchers to examine multiple systems of social relationships in sociocultural context.
