Factors for incomplete adherence to antiretroviral therapy including drug refill and clinic visits among older adults living with human immunodeficiency virus - cross-sectional study in South Africa

ObjectivesTo assess adherence outcomes to antiretroviral therapy (ART) of recipients 50 years in Soweto, South Africa. MethodsThis was a secondary data analysis for a cross-sectional study at two HIV clinics in Soweto. Data on ART adherence and covariates were gathered through structured interviews with HIV 878 persons living with HIV (PLHIV) receiving ART. Logistic regression analysis was used to assess associations. ResultsPLHIV 50 years (n = 103) were more likely to miss clinic visits during the last six months than PLHIV aged 25-49 (OR 2.15; 95%CI 1.10-4.18). PLHIV 50 years with no or primary-level education were less likely to have missed a clinic visit during the last six months than PLHIV with secondary- or tertiary-level education in the same age category (OR 0.3; 95%CI 0.1-1.1), as were PLHIV who did not disclose their status (OR 0.2; 95%CI 0-1.1). There was no evidence of increased risk for non-adherence to ART pills and drug refill visits among older PLHIV. ConclusionMissing a clinic visit was more common among older PLHIV who were more financially vulnerable. Further studies are needed to verify these findings and identify new risk factors associated with ART adherence.
