Thirty Years of United Nations Inter-Agency Working Group's Global, Regional, and National Maternal Mortality Estimates Revisited.

Over the last three decades, the United Nations interagency working group series of model-based maternal mortality estimation showed a significant reduction in maternal mortality ratio (MMR) at global, regional, and national levels. However, the contribution of sub-Saharan Africa for the global maternal deaths in 2020 was nearly two-fold higher than before, and the top five countries with high burden of maternal deaths remained unchanged after four decades. In this commentary, we argue that not all countries with high maternal deaths had high MMR; the lower MMR was noted as shadowing the large number of maternal deaths in countries with high rates of total births. We critically appraised the changes and challenges in maternal mortality measurements. We recommend the use of multiple indicators and categorizing the absolute number of maternal deaths to assess individual countries' maternal health status. As the majority of maternal deaths are preventable and all maternal deaths are catastrophic to the family, estimating the absolute number of maternal deaths should be given equal weight in future research undertakings.
