Southern Africa has long been facing a catastrophic HIV/AIDS crisis. At the end of 2001, more than 28 million of the world's estimated 40 million people living with HIV/AIDS were from Sub-Saharan Africa (AIDS, 2002). In South Africa, more than 4.7 million people are infected with HIV (AIDS, 2002). While studies in Africa have recently begun to examine social-behavioral HIV risk factors, virtually unknown are the patterns of neurocognitive dysfunction that result from the use of various drugs as well as the degree to which resulting cognitive deficits are associated with elevated injection- and sex-risk behaviors the lead to HIV infection. This presentation will describe organizational activities and summarize preliminary data collected for a NIDA-funded project to examine neurocognitive risk factors of HIV seroconversion among injection and non-injection drug users in South Africa. The primary aim of the longitudinal pilot study is to estimate the magnitude of a suspected causal relationship between executive dysfunction and HIV-risk behaviors, while adjusting for time-invariant (e.g., sex, ethnicity) and time-varying (e.g., degree of drug abuse) covariates. We also seek to evaluate the degree to which variations in drug type, frequency, and route of administration lead to distinct executive dysfunctions that predispose South African drug users to engage in high risk injection practices or sex behaviors.
