A Scoping Review of the Prevalence of Preeclampsia and its Contributions to Maternal and Perinatal Mortality in Nigeria

Abstract

Preeclampsia is a major cause of maternal and perinatal morbidity and mortality worldwide, particularly in low- and middle-income countries. This scoping review aims to map the existing literature on the prevalence of preeclampsia in Nigeria over the past 5 years and examine its contributions to maternal and perinatal mortality. The study utilized a scoping approach to map out the current situation and offer insights into potential interventions and future research directions. To include recent evidence, the search focused on articles published from January 2020 to January 2025. The quality of the studies included was assessed using the Critical Appraisal Skills Programme checklists for quantitative and qualitative studies. The review identified several sociodemographic and clinical factors associated with the prevalence and contributions to maternal mortality in Nigeria. The findings of this scoping study provide valuable insights into the current state of knowledge on the burden and the need for further research and policy interventions to address this critical public health issue. By addressing this burden, Nigeria can improve maternal health outcomes and contribute to achieving global health targets, including the Sustainable Development Goals.
