How to “Live a Good Life”: Aging and HIV Testing in Rural South Africa [PDF]
Journal of Aging and Health, 2018 Objective: The African HIV epidemic is aging, yet HIV testing behavior studies either exclude older persons or include too few to say much about age differences. Method: Strategically combining focus group interviews (participants in 40s/50s/60s-plus age groups) and survey data from rural South Africa (where HIV prevalence peaks in the late 30s, but ...
