OBJECTIVES: To analyse the association between socio-economic
                status (SES) and HIV in Manhica, a district of Southern
                Mozambique with one of the highest HIV prevalences in the world.
                METHODS: Data were gathered from two cross-sectional surveys
                performed in 2010 and 2012 among 1511 adults and from the
                household census of the district's population. Fractional
                polynomial logit models were used to analyse the association
                between HIV and SES, controlling for age and sex and taking into
                account the nonlinearity of covariates. The inequality of the
                distribution of HIV infection with regard to SES was computed
                through a concentration index. RESULTS: Fourth and fifth wealth
                quintiles, the least poor, were associated with a reduced
                probability of HIV infection compared to the first quintile (OR
                = 0.595, P-value = 0.009 and OR = 0.474, P-value < 0.001,
                respectively). Probability of HIV infection peaked at 36 years
                and then fell, and was always higher for women regardless of age
                and SES. HIV infection was unequally distributed across the SES
                strata. CONCLUSIONS: Despite the high HIV prevalence across the
                entire population of Manhica, the poorest are at greatest risk
                of being HIV infected. While women have a higher probability of
                being HIV positive than men, both sexes showed the same
                infection reduction at higher levels of SES. HIV interventions
                in the area should particularly focus on the poorest and on
                women without neglecting anyone else, as the HIV risk is high
                for everyone.
