Abstract

Wealthier individuals do better than poorer ones on most measures of health status including malnutrition, morbidity, mortality, and health care utilization. It is reasonable to expect that poverty increases individual vulnerability to HIV/AIDS in the same manner. This study examines the association between wealth and HIV serostatus to identify what specific characteristics and behaviors of the wealthier are associated with HIV infection, and to what extent confounding factors such as place of residence and other risk factors mediate this association Data are from eight national Demographic and Health Surveys in sub-Saharan Africa— Kenya, Ghana, Burkina Faso, Cameroon, Tanzania, Lesotho, Malawi, and Uganda—conducted during 2003-2005. Dried blood spot samples were collected for HIV testing, following internationally accepted ethical standards and laboratory procedures. HIV test results were linked anonymously to the characteristics and risk behaviors of adult respondents. The association between household wealth and HIV serostatus is examined using both descriptive and multivariate statistical methods. Wealth is measured by an index based on household ownership of durable assets and other amenities. This study finds that, contrary to evidence for other infectious diseases and theoretical expectations, in sub-Saharan Africa HIV prevalence is not disproportionately higher among adults living in poorer households. In all eight countries included in this study, wealthier men and women tend to have higher prevalence of HIV than poorer ones. Accounting for various underlying factors and proximate determinants explains much of this positive association, but in most cases wealthier adults remain at least as likely as poorer adults to be infected with HIV. The findings of this study question the basis for poverty-driven programs for HIV/AIDS prevention in developing countries. When planning and designing prevention, care, and treatment efforts, program planners and policymakers need to adjust to the reality that HIV prevalence is not necessarily higher among the poorer.
