This study is based on secondary analysis of recent data from the international DHS programme from 22 countries in sub-Saharan Africa where HIV/AIDS test data are available. The specific objectives are to: (i) determine socio-economic and demographic risk factors of HIV/AIDS infection among males and females; (ii) explore the role of proximate factors, relating to HIV/AIDS awareness, stigma/prejudice and sexual behaviour; and (iii) examine national and sub-national variations in HIV infection and risk factors. The linkage of DHS HIV test results to the full DHS survey record provides a unique opportunity for an in-depth analysis of the socio-demographic and behavioral factors associated with HIV infection. The analysis is based on multilevel modelling, and places particular emphasis on national and sub-national variations in factors associated with HIV/AIDS. We further highlight regional inequalities in HIV infection by mapping the residual spatial effects using geo-additive models, via Bayesian approach.
