Mental Disorder in People Living with HIV/Aids in South Africa

Abstract

We investigate the prevalence of mental disorder in people living with HIV/AIDS in a developing country context and examine the relationship between the presence of mental disorder and various independent variables. Nine-hundred HIV positive people were interviewed in 18 recruitment sites across five provinces in South Africa, using a cross-culturally validated diagnostic instrument and a structured socio-demographic and health information questionnaire. Prevalence of mental disorder was established using the Composite International Diagnostic Interview (CIDI). Chi-square, Fischer exact test, and binary logistic regression examined the relationship between mental health disorders and demographic characteristics, disease stage, CD4 count, and whether the person was on anti-retroviral treatment. A number of respondents (43.7%) were found to have a diagnosable mental disorder. Depression was the most common disorder (11.1% major and 29.9% mild depression), followed by alcohol abuse disorder (12.4%). The presence of mental disorder was significantly associated with gender, employment status, having children, and the clinical stage of the disease. Gender and the stage of disease were the best predictors of mental disorder. Rates of mental disorder were substantially higher in people living with HIV/AIDS than generally found in populations in developing countries and similar to HIV positive groupings in developed countries. Viral impacts on the brain, psychological reactions, and social conditions all contributed to the higher prevalence rates. Mental health interventions need to become a central part of comprehensive HIV/AIDS support, care, and treatment programmes.
