Objectives: To examine risk factors for HIV-1 infection in three geographic strata (main road trading centers that service local and international traffic, small trading villages on secondary dirt roads that serve as foci for local communications, and agricultural villages of main and secondary roads) in Rakai District, Uganda. Design and methods: Serological, sociodermographic, knowledge/behaviors and health survey conducted in 21 randomly selected community clusters; complete data were collected for 1292 consenting adults. Results: Fifteen percent of the men and 24% of the women were HIV-1-positive. On univariatte analysis, several sociodemographic and behavioral factors were significantly associated with risk of HIV infection, including age, place of residence, travel, occupation, marital status, number of sex partners, sex for money or gifts, history of sexually transmitted disease (STD), and histtory of injections. On multivariate analysis, age, residence and number of sex partners rained significanly associated with HIV infection in both sexes; a history of STD and not having been circumcised were significant in men. There was a significant interactions between place of residence and reported number of sex partners; for any given level of sexual activity, the risk of HIV infection was markedly increased if the background community prevalence was high. Conclusions: Sexual transmission appears to be the primary behavioral risk factors for infection, but the risks associated with this factor vary substantialy between the three geographic strata. These data can be used to design targeted interventions.
