Determinants of multiple sexual partners and condom use among adults were assessed through a population-based survey in one urban, one semi-urban and one rural community in the Arusha region, northern Tanzania. The study samples were obtained by randomly selecting clusters of 10 households from the 3 communities. Informed verbal consent was sought from each respondent for participation in the study. High-risk sexual behaviours and condom use were assessed using a structured questionnaire. It was observed that significantly more men than women reported having multiple sexual partners (49% vs 25.2%; OR = 1.69; 95% CI = 1.51-1.90) and urban men were significantly more likely to report having multiple sexual partners than men in rural areas. In both men and women, early sexual debut was associated with having multiple sexual partners while travel, alcohol use, and sex under the influence of alcohol were significantly associated with multiple sexual partners in men only. AIDS-related discussion was significantly associated with having fewer sexual partners in both men and women. Of the 1551 respondents, 320 (20.6%) reported having ever used a condom and of the 320 respondents who had ever used a condom, 34 (10.6%) reported having used it at the last sexual intercourse. Significantly more men than women reported having ever used a condom (34.1% vs 14.1%; OR = 1.77; 95% CI = 1.56-2.01). In both men and women, early sexual debut and being young, unmarried, travelling out of the Arusha region and having multiple sexual partners were associated with increased condom use. For both men and women, frequent discussion of AIDS with family members or friends was associated with increased condom use. These data suggest that interventions targeting adolescents and young adults may be effective for control of HIV transmission in Tanzania. In particular, creation of opportunities for people to come together and discuss AIDS might be an important strategy.
