Includes bibliographical references / Objective: The main aim of this thesis is to analyze data from the South African Stress and Health (SASH) study and , for the first time, generate information on the epidemiology of traumatic event s (TEs) and posttraumatic stress disorder (PTSD), and on the association of TEs with other psychopathological and physical health outcomes. Methods: A literature review was done to provide information current knowledge in the field. Cross - tabulations, Chi - squared tests and logistic regression analyses were then conducted SASH data to determine the prevalence of the different types of trauma and PTSD and the associations between the sociodemographic variables and TEs and PTSD on the one hand, and TEs and PTSD, other psychopathology and chronic physical conditions on the other . Results: The most common traumatic events were the unexpected death of a loved one and witnessing trauma. Lifetime prevalence of PTSD was 2.3%, and the conditional prevalence of PTSD after trauma exposure was 3.5%. PTSD conditional risk and burden were both highest for witnessing trauma. Witnessing trauma was commonest among males and those with low - average education. There was statistically significant association between witnessing and PTSD, mood, and anxiety disorders. Exposure to any TE significantly increased the odds of all the physical conditions, and the odds of having a physical condition were directly related to the number of lifetime traumatic events. Sexual violence and unexpected death of a loved one significantly increased the odds of all the e physical conditions assessed, while war events were only associated with respiratory conditions. Apart from war events, accidents and witnessing trauma were associated with the fewest physical conditions. Conclusions: Consistent with the literature, trauma and PTSD in South Africa are not distributed according to the socio - demographic factors or trauma types observed in other countries. Witnessing trauma is common in South Africa and increases the risk of mood and anxiety disorders. Finally, TE exposure is associated with chronic physical conditions in a dose - response manner. Trauma interventions must therefore focus also on those not directly affected, and routine evaluation for chronic physical conditions is recommended for survivors of all trauma.
