Pregnancy-Related Deaths by Hispanic Origin, United States, 2009-2018.

To describe pregnancy-related mortality among Hispanic people by place of origin (country or region of Hispanic ancestry), 2009-2018. We conducted a cross-sectional descriptive study of pregnancy-related deaths among Hispanic people, stratified by place of origin (Central or South America, Cuba, Dominican Republic, Mexico, Puerto Rico, Other and Unknown Hispanic), using Pregnancy Mortality Surveillance System data, 2009-2018. We describe distributions of pregnancy-related deaths and pregnancy-related mortality ratios (number of pregnancy-related deaths per 100,000 live births) overall and by place of origin for select demographic and clinical characteristics. For 2009-2018, the overall pregnancy-related mortality ratio among Hispanic people was 11.5 pregnancy-related deaths per 100,000 live births (95% confidence intervals [CI]: 10.8-12.2). In general, pregnancy-related mortality ratios were higher among older age groups (, 35 years and older) and lower among those with higher educational attainment (, college degree or higher). Approximately two in five pregnancy-related deaths among Hispanic people occurred on the day of delivery through 6 days postpartum. Place of origin-specific pregnancy-related mortality ratios ranged from 9.6 (95% CI: 5.8-15.0) among people of Cuban origin to 15.3 (95% CI: 12.4-18.3) among people of Puerto Rican origin. Hemorrhage and infection were the most frequent causes of pregnancy-related deaths overall among Hispanic people. People of Puerto Rican origin had a higher proportion of deaths because of cardiomyopathy. We identified differences in pregnancy-related mortality by place of origin among Hispanic people that can help inform prevention of pregnancy-related deaths.
