The purpose of this analysis was to conduct an exploratory study designed to identify bivariate correlates of condom use beliefs, and Marijuana use among a sample of South African Inmates. Participants were inmates from 4 prisons in the provinces of KwaZulu-Natal and Mpumalanga provinces. In total, 357 inmates participated in the parent study of which 350 are included in this analysis. The questionnaire was developed in English then translated into Zulu. It was administered both in English (Mpumalanga) and Zulu (Kwazulu-Natal). Significance tests were conducted using univariate logistic regressions to examine the independent associations of condom use beliefs, lifetime occurrence of sexually transmitted infections, and self-reported marijuana use before incarceration. Inmates who reported using marijuana were more likely to suggest that condoms were embarrassing to use (odds ratio=1.08, 95% confidence interval=0.55-2.11) and report a lifetime occurrence of a sexually transmitted infection (odds ratio=1.45, 95% confidence interval=0.94-2.23). Findings suggest that it is also important to explore beliefs for not using condoms consistently and with regular partners among inmate populations.
