Research shows that in the Caribbean one-third of people living with HIV continue to engage in unprotected sexual practices. Childhood sexual abuse (CSA) and HIV-related risk behaviors have been found to play a contributory role in HIV transmission. We aimed to analyze gender differences in the association between CSA and substance use and sexual risk behaviors among Haitians living with HIV. A total of 276 HIV-positive individuals participated in this study with 56% experiencing sexual abuse during childhood.
