Global, regional, and national levels of maternal mortality, 1990-2021: a systematic analysis for the Global Burden of Disease Study 2021.

ABSTRACT:

Background

Despite global declines in the maternal mortality ratio (MMR), significant disparities persist across regions and socioeconomic strata. This study aims to examine spatiotemporal trends in MMR from 1990 to 2021, with a specific breakdown by age, socio-demographic index (SDI) and cause of death, to better clarify the underlying determinants of these patterns.

Methods

Utilizing data from the Global Burden of Disease (GBD) Study 2021, we examined MMR trends attributable to ten distinct causes across 204 countries and territories from 1990 to 2021. Analyses were stratified by the SDI, and temporal patterns in age-specific and regional MMR distribution were evaluated.

Results

The global MMR declined from 260.02 per 100,000 live births in 1990 to 147.77 per 100,00
