Gibbs A, et al. - Researchers performed cross-sectional surveys among heterosexual men in Johannesburg and Durban, South Africa, who were enrolled in intervention trials to ascertain how the experience of traumatic events is associated with HIV-risk behaviors. In adjusted logistic regression, witnessing the murder of a family member, witnessing a murder of a stranger, experiencing excessive pain, being kidnapped, and witnessing a rape was correlated with transactional sex and four or more sex partners among 2,394 men. In this population, poverty, traumatic experiences, and gender inequalities in combination were noted influencing the HIV-risk behaviors. They recommend lowering men's experiences of poverty and trauma, changing gender norms, and lowering the mental health impact of trauma to be part of HIV-prevention interventions.
