Objective: Obesity is a major long-term concern in HIV-positive patients due to the pathogenic link between obesity and noncommunicable chronic diseases (NCDs). We aim to characterize changes in BMI over time on antiretroviral therapy (ART) and investigate the association between weight gain and survival in South Africa.
Design and methods: A prospective cohort study among HIV-positive adults on first-line ART between April 2004 and 2015 in Johannesburg, South Africa. We used latent class growth modeling (adjusted for age, sex and CD4รพ cell count) to identify groups of individuals with similar patterns of change in BMI over time.
