Objective: To report the global burden of maternal disorders and their main subcategories in 195 countries and territories between 2007 and 2017.
Methods: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 estimated maternal disease burden at global, regional, and country levels. Maternal disorders were disaggregated into 10 categories, and estimated incidence and disability-adjusted life years (DALYs) of maternal disorders were reported separately. Indicators were estimated in different geographic settings and different sociodemographic index (SDI) regions. Based on GBD 2017 estimates, we systematically examined the incidence and DALYs of maternal disorders and their main subcategories at the global, regional, and national levels during the period from 2007 to 2017 by age and SDI.
Results: Globally, a total of 7.98 million maternal disorders occurred in 2017, with a 4.33% (95% uncertainty interval [UI] 3.24%-5.60%) decrease in age-standardized incidence rate and a more significant decrease (30.26%) in the age-standardized rate of DALYs. Most incidences and DALYs were found in low-income and middle-income countries, especially in the sub-Saharan region. The greatest incidence of maternal disorders was found to be in maternal abortion and miscarriage (2.00 million), and the highest disease burden was in maternal hemorrhage (2.23 million).
Conclusion: A slight increase in the incidence of maternal disorders and substantial reductions in DALYs of overall maternal disorders and their main subcategories were found from 2007 to 2017, especially in low-income countries and the sub-Saharan region. Maternal hemorrhage, hypertensive disorders, and indirect maternal death were the top three causes of maternal disorders disease burden.
