Background: Studies have reported that infection with certain sexually transmitted diseases STD , such as chancroid, gonorrhea, and genital herpes, enhances the probability of human immunodeficiency virus HIV transmission by sexual contact with an infected partner. Epidemiologic studies vary in design from longitudinal to cross-sectional, with varying periods of follow-up or retrospective history of exposure to STD. The major difficulty in assessing the results of past work centers on the validity and precision of widely used measures of association, such as relative risk RR and odds ratio OR , in situations in which common behavior e. Analysis was performed using Monte-Carlo simulation. The adjusted CIR, HRR, and PR tend to underestimate the strength of the true association specified in the model in both longitudinal and cross-sectional designs.
