Pregnancy-related mortality in Hispanic women in the United States

To examine pregnancy-related mortality among Hispanic women in the United States.

We used data from the Centers for Disease Control and Prevention's ongoing Pregnancy Mortality Surveillance System to examine all reported pregnancy-related deaths (deaths during or within 1 year of pregnancy that were caused by pregnancy, its complications, or treatment) in states that reported Hispanic origin for 1979-1992. The pregnancy-related mortality ratio was defined as the number of pregnancy-related deaths per 100,000 live births.

For the 14-year period, the overall pregnancy-related mortality ratio was 10.3 deaths per 100,000 live births for Hispanic women, 6.0 for non-Hispanic white women, and 25.1 for black women. In Hispanic subgroups, the pregnancy-related mortality ratio was 9.7 for Mexican women and ranged from 7.8 for Cuban women to 13.4 for Puerto Rican women. Pregnancy-induced hypertension was the leading cause of pregnancy-related death for Hispanic women overall.

Pregnancy-related mortality ratios for Hispanic women were higher than those for non-Hispanic white women, but markedly lower than those for black women. The similarity in socioeconomic status between Hispanic and black women was not an indicator of similar health outcomes. Prevention of pregnancy-related deaths in Hispanic women should include investigation of medical and nonmedical factors and consider the heterogeneity of the Hispanic population.
