The association between poly-substance use, coping, and sex trade among black South African substance users.

The current study examined the relationship between poly-substance use and sex trade among 343 black South African substance users recruited from the Pretoria region between 2002 and 2006 (57% males; mean age 24 years). The assessment comprised a HIV-risk behavior interview, urinalysis to confirm self-report of drug use, and an HIV test. Logistic regression analyses indicated poly-substance use was positively associated with sex trade among persons using drugs to cope with stress. Results indicate the importance of considering coping strategies as modifiable psychosocial factor related to sexual risk-taking behaviors and substance use. The study's implications and limitations are discussed.
