Background Little is known about women who have experienced a recent rape, and how they differ from women without this exposure. Identifying factors linked to rape is important for preventing rape and developing effective responses in countries like South Africa with high levels of sexual violence. Objective To describe the socio-demographic and health profile of women recently exposed to rape and to compare them with a non-rape-exposed group. Methods The Rape Impact Cohort Evaluation Study (RICE) enrolled 852 women age 16–40 years exposed to rape from post-rape care centres in Durban (South Africa) and a control group of 853 women of the same age range who have never been exposed to rape recruited from public health services. Descriptive analyses include logistic regression modelling of socio-demographic characteristics associated with recent rape exposure. Results Women with recent rape reported poorer health and more intimate partner violence than those who were not raped. They had a lower likelihood of having completed school (Odds Ratio [OR] 0.46 95% Confidence Interval (CI): 0.24–0.87) and dependence on a government grant as a main source of income (OR 0.61: 95%CI 0.49–0.77). They were more likely to live in informal housing (OR 1.88 95%CI: 1.43–2.46) or rural areas (OR 2.24: 95%CI 1.61–3.07) than formal housing areas – however they were also more likely to report full-time employment (OR 4.24: 95%CI 2.73–6.57). Conclusion The study shows that structural factors, such as lower levels of education, poverty, and living in areas of poor infrastructure are associated with women’s vulnerability to rape. It also shows possible protection from rape afforded by the national financial safety net. It highlights the importance of safe transportation in commuting to work. Preventing rape is critical for enabling women’s full social and economic development, and structural interventions are key for reducing women’s vulnerability.

“…Assuming a HIV incidence of 9 and 6% among the rape-exposed and nonexposed groups respectively [ 13 ], and to achieve 90% power to detect a significant difference in HIV incidence, 1008 participants were to be recruited in each cohort. In practice, however, recruiting rape-exposed participants took longer than anticipated resulting in logistical and budgetary constraints.…”

Objective: To determine the incidence of HIV acquisition in women postrape compared with a cohort of women who had not been raped. Design: A prospective cohort study. Methods: The Rape Impact Cohort Evaluation study based in Durban, South Africa, enrolled women aged 16–40 years from postrape care services, and a control group of women from Primary Healthcare services. Women who were HIV negative at baseline (441 in the rape-exposed group and 578 in the control group) were followed for 12–36 months with assessments every 3 months in the first year and every 6 months thereafter. Multivariable Cox regression models adjusted for baseline and time varying covariates were used to investigate the effect of rape exposure on HIV incidence over follow-up. Results: Eighty-six women acquired HIV during 1605.5 total person-years of follow-up, with an incident rate of 6.6 per 100 person-years [95% confidence interval (CI): 4.8–9.1] among the rape exposed group and 4.7 per 100 person-years (95% CI: 3.5–6.2) among control group. After controlling for confounders (age, previous trauma, social support, perceived stress, multiple partners and transactional sex with a casual partner), women exposed to rape had a 60% increased risk of acquiring HIV [adjusted hazard ratio: 1.59 (95% CI: 1.01–2.48)] compared with those not exposed. Survival analysis showed difference in HIV incident occurred after month 9. Conclusion: Rape is a long-term risk factor for HIV acquisition. Rape survivors need both immediate and long-term HIV prevention and care.

Rape stigma, both external and self-stigmatization (self-blame), is associated with adverse health outcomes. Understanding its origins and resilience factors is critical for reducing and preventing it. We describe the prevalence of rape stigma, the characteristics of women experiencing it and the pathways to experiencing greater stigma. The Rape Impact Cohort Evaluation study enrolled 852 women aged 16-40 years who had been raped from post-rape care centres in Durban, South Africa. We present a descriptive analysis of the baseline data, a multinomial logistic regression model of factors associated with different levels of stigma and a structural equation model (SEM). Most women reported stigmatizing thoughts or experiences, with self-stigmatizing thoughts being more prevalent than external stigmatization. The multinomial model showed that experiences of childhood or other trauma, emotional intimate partner violence (IPV), having less gender equitable attitudes and food insecurity were significantly associated with medium or high versus low levels of stigma. Internal and external stigma were significantly associated with each other. Women who had been previously raped reported less stigma. The SEM showed a direct path between food insecurity and rape stigma, with poorer women experiencing more stigma. Indirect paths were mediated by more traditional gender attitudes and childhood trauma experience and other trauma exposure. Our findings confirm the intersectionality of rape stigma, with its structural drivers of food insecurity and gender inequality, as well as its strong association with prior trauma exposure. Rape survivors may benefit from gender-empowering psychological support that addresses blame and shame.
