Negative pregnancy outcomes (NPOs) are pregnancy-related occurrences that affect the health of mothers and children in the course of child bearing. NPOs may manifest as a miscarriage, stillbirth or preterm birth. Nigeria contributes up to 12% of the global burden of stillbirths, and a significant number of these occurrences are connected with inadequate utilisation of antenatal care services. This study investigated the influence of social factors such as attitudes towards antenatal clinics, religious affiliation, education and spousal discussion on antenatal service attendance and experiences of NPOs among ever-married men and women in Shomolu, Lagos State, Nigeria. A cross-sectional survey was utilised for data collection among 480 participants. Results showed that religion and educational level of husbands were significant predictors of their wives’ experiences of NPOs. Among women, Muslims and adherents of traditional religion were respectively 2.49 and 5.65 times more likely to experience NPOs relative to their Christian counterparts. Similarly, women who registered for antenatal care at a conventional facility were 1.14 less likely to experience NPOs than their unregistered counterparts. Findings also indicated a statistically significant difference between the mean number of antenatal care attendance by women who discussed with their husbands when to become pregnant and those who did not discuss it with their husbands. As a way forward, pregnant women should be given the necessary support to seek antenatal care from skilled service providers at conventional centres.
