Socio-economic Status and Associated Factors in the Uptake of HIV Testing: Findings from the South African Population-based National Household Survey Conducted in 2017
Abstract Background: Improved understanding of barriers to HIV testing is important for reaching the first of the UNAIDS 90-90-90 targets, which states that 90 percent of HIV positive individuals ought to know their HIV status. This study examined socioeconomic status (SES) factors and related covariates associated with HIV testing uptake in the general population in South Africa. Information on SES and HIV testing may impact the HIV treatment and care cascade and prevention of HIV transmission. Methods: This study used data obtained from a national cross-sectional, population-based household survey conducted in 2017 using a multi-stage stratified random cluster sampling design. A composite SES score was created using multiple correspondence analyses of household assets; households were classified into wealth quintiles and dichotomized into low SES/poorest (lowest 3 quintiles) and high SES/less-poor (highest 2 quintiles). Bivariate and multivariate logistic regression models were fitted to analyse associations between the uptake of HIV testing and a set of socio-demographic and HIV-related variables. Results: HIV testing uptake was 73.8% and 76.7% among low and high SES household, respectively, both of which were below the first 90 target. The findings showed increased uptake of HIV testing was associated with being female and having a higher educational level independent of SES. Decreased uptake of HIV testing was associated with being from White and Indian/Asian race groups, residing in rural formal areas, alcohol consumption, and high self-perceived risk of HIV infection.Conclusions: We found that HIV testing uptake was similar for people from both low and high SES. However, interventions aimed at improving HIV testing in order to reach the first 90 target, should target males, all race groups, those with low education attainment, and those residing in rural formal areas. Reaching the first target will require efforts to improve community knowledge, and awareness about the negative impact of alcohol use and address HIV risk perception.
