Network determinants of marijuana, alcohol and HIV risk among formerly incarcerated Latino men

BACKGROUND: HIV/AIDS among formerly incarcerated Latino men (FILM) is a critical public health concern. Latinos are both disproportionately affected by the HIV/AIDS epidemic and overrepresented in correctional facilities in the United States. Nationwide, Latinos represent more than a quarter of all inmates and 17% of the total population in State correctional facilities. An estimated 1.8% of State prison inmates are HIV positive and studies indicate that the proportion of Latino inmates with HIV is 8 times higher than the proportion of White inmates with HIV. Upon release, FILM engage in high rates of HIV-related sexual risk behavior. Formerly incarcerated men have sexual intercourse shortly after release, have high rates of unprotected sex, and engage in sex after using drugs or alcohol. Despite high levels of vulnerability to HIV-infection, HIV-prevention interventions targeting the unique needs of FILM are scarce. This study examines the relationships between network and behavioral determinants on FILM HIV risk behavior. METHODS: A cross-sectional survey was administered to a non-random sample of 200 FILM and 200 nominated network referents in the New York City metropolitan area. RESULTS: The survey will conclude in August 2010. We will present results on the characteristics of FILM social networks, as well as the social network risk factors that increase unprotected vaginal and anal intercourse in general and specifically in combination with marijuana/alcohol use.
