Factors associated with non-use of ART among men living with HIV in South Africa: findings from a population-based household survey

Abstract

AbstractIntroductionAlthough South Africa adopted the World Health Organization’s Test and Treat strategy for HIV epidemic control in 2016, antiretroviral therapy (ART) treatment initiation and retention remain below target. In 2017, an estimated 56.3% of men living with HIV were on ART. We aimed to investigate factors associated with non-use of ART among men in South Africa.MethodsUtilizing data from the fifth South African National HIV Prevalence, Incidence, Behavior and Communication (SABSSM V) cross-sectional survey conducted in 2017, a subset of data from HIV-positive men was stratified based on presence/absence of antiretroviral drugs (ARVs) detected in dried blood spot samples. Data were weighted to be representative of the national population and analyzed using multivariable logistic regression to assess predictors of non-use of ART; p<0.05 was considered significant.ResultsA total of 6,920 men aged ≥15 years old were enrolled in the study, of whom 953 (13.8%) tested HIV-positive. Among those HIV-positive, 810 (85%) had a known ARV test result: 470 (58%) had ARVs detected, and 340 (42%) did not have ARVs detected. Non-use of ART in men was associated with high-risk alcohol use (adjusted odds ratio (AOR)=3.68, 95% confidence interval (CI): 1.03-13.23), being a widower compared to being unmarried (AOR=6.99, 95%CI: 1.46-33.42), and having drug-resistant HIV (AOR=28.12, 95%CI: 13.89-56.94). Per year increase in age (AOR=0.67, 95%CI: 0.47-0.96), residence in rural tribal localities compared to urban localities (AOR=0.38, 95%CI: 0.18-0.78), or having a co-morbidity such as tuberculosis or diabetes (AOR=0.06, 95%CI: 0.03-0.14) were positively associated with ART use.ConclusionsNon-use of ART was strongly associated with HIV drug resistance. Young men who are living with HIV, those with high-risk alcohol use, and widowers, should be a priority for HIV programming and linkage to care. Identifying interventions that are effective at linking these men to ART will help reduce the burden of HIV in South Africa.
