This research assesses changes in maternal mortality ratios in Brazil, focusing on the impact of the COVID-19 pandemic and ongoing regional disparities.
Analyzed annual maternal mortality ratios from 2000 to 2023 across 26 states and the Federal District using interrupted time-series segmented regression.
Estimated pre-pandemic trends, changes during COVID-19, and post-pandemic recovery phases with Newey-West robust standard errors.
Calculated the median absolute deviation, coefficient of variation, and p90/p10 ratio to evaluate changes in territorial inequality.
Identified a modest pre-pandemic upward trend in maternal mortality and marked worsening during the COVID-19 period.
Post-pandemic recovery was observed, but interstate disparities significantly widened during the pandemic.
Findings indicate systemic health vulnerabilities remain in historically at-risk states, threatening progress toward SDG 3.1.
