This analysis aimed to identify correlates of syphilis sero-status among men, women and cohabiting couples in the 2001 Zambian Demographic and Health Survey which included syphilis testing. Socio-demographic, behavioural and mobility characteristics were analysed for association with syphilis sero-positivity for all men, all women and the male and the female partner in matched cohabiting couples. Sero-positive men were more likely to report having >1 partner in the last year and to be divorced. For women, marriage and sex with a partner known for <1 month increased the odds of infection. There were marked regional differences in syphilis status. For both male and female partners in couples there were individual correlates of syphilis sero-status that acted independently of the partner’s sero-status and the partner’s duration of residence was also important. After modelling the geographical variations in syphilis prevalence behavioural and mobility correlates of syphilis sero-status remained significant.
