Gender Based Violence (GBV) and HIV/AIDS are major health and social problems affecting
women and men in African countries Tanzania included. While both men and women are victims of
GBV and HIV/AIDS, women are more vulnerable than men. Socio-economic, biological and
cultural factors are believed to exacerbate the problem. The current study explores the link
between gender based violence and the spread of HIV/AIDS. Using Serengeti District as a study
area, a cross-sectional descriptive survey was conducted using a mixed method/approach, whereby
administering a questionnaire, focus group discussion (FGDs) and in-depth interviews were
employed. Twenty nine key informants and 64 participants were selected for FGDs, while 16
women (victims of GBV and HIV/AIDS) were purposively selected for in- depth interview.
Qualitative information was analyzed using content analysis. GBV practices such as women to
women marriages emerged to be a predictor of HIV because young women married to old women
might have multiple relationships apart from the selected husband. Female Genital Mutilation
(FGM) and male circumcision are practiced using non sterilized knives which are culturally
believed to be sacred which also fuels the spread of HIV/AIDS. Other GBV practices include the
cleansing of the widow/widower; this is done through sexual contact between the widow and close
relative of the deceased husband or using a village cleanser. Wife battery was found to be caused
by husband or wife being suspected of involvement in extramarital relationship. Unfaithfulness of
spouses increases risks of acquiring HIV to couples. The study recommends involvement of
traditional leaders in the process of reducing GBV and HIV/AIDS spread. Awareness creation
towards the use of both female and male condoms is of utmost importance.
