Abstract
Introduction South Africa has the highest obesity and hypertension rates in the African region. In this cross-sectional study, we aimed to quantify the correlates and burden of obesity and their impacts on cardiometabolic conditions. Methods The study population was 80,270 men(41 %) and women(59 %) who participated in South African national surveys (2008-to-2017). Weighted-logistic regression models and the population attributable risk (PAR %) were used after accounting for the correlation structure of the risk factors in a multifactorial setting. Results Overall, 63 % of the women and 28 % of the men were either overweight or obese. Parity was identified as the most influential factor and exclusively associated with 62 % of the obesity in women; being married/cohabiting had the highest impact on obesity in men and associated with 37 % of the obesity. Overall, 69 % of them had comorbidities including hypertension, diabetes and heart disease. More than 40 % of the comorbidities were attributed to overweight/obesity. Conclusion Developing culturally appropriate prevention programs are urgently needed to raise awareness of obesity, hypertension and their impacts on severe cardiometabolic diseases. This approach would also significantly reduce COVID-19 related poor health outcomes and premature deaths.
