The role of social support in the association between childhood trauma and depression among HIV-infected and HIV-uninfected individuals.

Childhood trauma (CT) - emotional, physical or sexual abuse, or emotional or physical neglect - has been associated with HIV infection and can lead to poor health outcomes and depression in adulthood. Though the impact of CT on depression may be decreased by social support, this may not be true of individuals living with HIV, due to the additive traumatic effects of both CT and acquisition of HIV. This study examined social support, depression, and CT among HIV-infected (n = 134) and HIV-uninfected (n = 306) men and women. Participants (N = 440) were assessed regarding sociodemographic characteristics, CT, depression, and social support. Participants were racially and ethnically diverse, 36 ± 9 years of age on average, and 44% had an income of less than USD$500 a month. Among HIV-uninfected individuals, social support explained the association between depression in persons with CT ( b = 0.082, bCI [0.044, 0.130]). Among HIV-infected individuals, after accounting for sociodemographic characteristics, social support did not explain the association between depression and CT due to lower levels of social support among HIV-infected individuals [95% CI: -0.006, 0.265]. The quality of social support may differ among HIV-infected persons due to decreased social support and smaller social networks among those living with HIV. Depressive symptoms among those living with HIV appear to be less influenced by social support, likely due to the additive effects of HIV infection combined with CT.
