AIDS and risk: The handling of uncertainty in northern Tanzania.

Studies of sexual risk behaviour in the context of HIV/AIDS often utilize theories of risk which are predicated on the idea of the rational actor making choices, and thus operate with a strong notion of the autonomous individual. The underlying assumption is that a well-informed individual would strive to reduce risk and therefore choose not to engage in risky behaviour in sexual encounters. Drawing on longitudinal fieldwork in Arusha town and the surrounding districts in northern Tanzania, this paper explores how people draw on a complexity of knowledge and experience when they try to reduce the likelihood of contracting HIV. It shows how the embeddedness of social relationships, and the constraints of culture restrict the possible range of options, particularly for women. The paper examines the paired concepts of risk and trust, arguing that trust in a sexual relationship is gendered in particular ways. Gender hierarchies often place women in a subordinate position to men as a result of which women have to make compromises which put their health at risk. [ABSTRACT FROM AUTHOR]
