Understanding and preventing sexual and gender-based violence among South African youth during public health crises

The COVID-19 pandemic has had far-reaching consequences beyond the immediate threat of infection, exacerbating existing social inequalities and vulnerabilities, particularly in low- and middle-income countries. Among these, the risk of sexual and gender-based violence (SGBV) among young people emerged as a critical public health concern. This doctoral thesis investigates the impact of the COVID-19 crisis on SGBV exposure among adolescents and young adults aged 10-24 in South Africa-a country with high baseline rates of SGBV and stringent lockdown policies during the pandemic. The thesis is structured around four sub-studies embedded within two overarching studies: a longitudinal mixed-methods cohort of young people with and without HIV (the BUDDY study (Sub-studies l-II)) and a cluster randomized controlled trial assessing the impact of an empowerment-based self-defense intervention for girls (the No Means No (NMN) evaluation (Sub-studies III-IV)). Using a combination of quantitative and qualitative methods, the research explores the trajectories of SGBV during and after lockdowns, the psychosocial and structural drivers of violence, and the potential of targeted interventions to mitigate violence in public health crisis contexts. Findings from Sub-study I highlights a complex pattern of violence exposure, with notable perceived increases in community and household violence during the initial lockdown period. Risk factors such as common mental disorder symptomology, unemployment/being out of school, and food insecurity were associated with higher exposure to SGBV among youth. Trajectory modeling revealed distinct subgroups of youth experiencing persistent or fluctuating patterns of violence, influenced by mental health, and socioeconomic factors (Sub-study II). The NMN evaluation demonstrated that an 8-hour, COVID-adapted Empowerment Self-Defense curriculum had a positive impact on self-defense knowledge, and perceived feelings of confidence and sources of support among adolescent girls. However, the trial did ...
