Our study shows that by 2016, the prevalence of adolescent obesity was high in South Africa - more than 1 in 5 adolescents - which is nearly similar to that in Europe, yet South African girls may be at a greater odd for overweight and obesity in contrast to Europe, as well as adolescents from high earning families. South African local and contextual factors may be driving higher prevalence in specific sub-population. Our study also shows the need for frequent health-related data collection and tracking of adolescents' health in South Africa.
