title: Maternal mortality in northern Nigeria: findings of a health and demographic surveillance system in Zamfara State, Nigeria.
abstract: The aim of this study was to estimate: (1) the lifetime risk (LTR) of maternal death; and (2) the maternal mortality ratio (MMR) in the Zamfara State of northern Nigeria. Data from the Nahuche Health and Demographic Surveillance System were utilized using the 'sisterhood method' for estimating maternal mortality. Female respondents (15-49 years) from six districts in the surveillance area were interviewed, creating a retrospective cohort of their sisters who had reached the reproductive age of 15 years. Based on population and fertility estimates, we calculated the LTR of maternal death and the MMR. A total of 17,087 respondents reported 38,761 maternal sisters of whom 3592 had died and of whom 1261 were maternal-related deaths. This corresponded to an LTR of maternal death of 8% (referring to a period of about 10.5 years prior to the survey) and an MMR of 1049 deaths per 100,000 live births (95% confidence interval, 1021-1136). The study provides documented evidence of high maternal mortality in the study area and the state as a whole. Thus, there is a need to improve the health system with an emphasis on interventions that will accelerate reduction in MMR such as the availability of skilled birth attendants and emergency obstetric care, promotion of facility delivery and antenatal care attendance. This can be achieved through a holistic approach and is critical in order to accelerate progress in meeting the Millennium Development Goal of maternal mortality reduction.
