title: Correlates of depressive symptoms among HIV-positive injection drug users: the role of social support.
abstract: Using cross-sectional data from an ethnically diverse sample of HIV-positive injection drug users (IDUs), we sought to identify correlates of depressive symptoms. We were particularly interested in whether perceived social support was associated with depression among HIV-positive IDUs and whether social support buffered adverse effects of other correlates. Data were collected from a sample of HIV-positive IDUs recruited from a variety of venues in the New York City and San Francisco metropolitan areas in the USA. Multiple regression analysis identified four significant correlates of depressive symptoms. Perceived social support and having a regular place for HIV medical care were significantly associated with lower levels of depressive symptoms, while history of mental health problems and non-injection polydrug use were significantly associated with higher levels of depressive symptoms. Moreover, a significant interaction effect was found between social support and non-injection polydrug use, indicating that social support buffers the association between non-injection polydrug use and depression. These results suggest that increasing social support might be a useful tool for HIV-positive IDUs in reducing depression and the adverse effect of non-injection polydrug use.
