South Africa has the largest number of people living with HIV/AIDS in the world and a rapidly aging population. In recent years, with expanded availability of ART, many adults are aging with HIV, and further, increasing numbers are acquiring HIV at older ages. This study aims to understand life course and contextual variation in HIV risk and protective behaviors among adults as they transition from middle to older ages in a high HIV prevalence setting in rural South Africa. The study examines how sexual risk and HIV prevention strategies are shaped by life course stage, gender, and context, in an effort to inform possible interventions, prevention efforts, and treatment programs for older populations and for younger cohorts aging into this population with or without HIV.
