RESUMO
PURPOSE: African-American women have a 2- to 4-fold increased risk of pregnancy-related death compared with Caucasian women. We conducted this study to determine if differences in a combination of socioeconomic and medical risk factors may explain this racial disparity in pregnancy-related death. METHODS: Pregnancy-related deaths of African-American (N=60) and Caucasian (N=47) women were identified from review of pregnancy-associated deaths (N=400) ascertained through cause of death on death certificates, electronic linkage of birth and death files, and review of the hospital discharge database for the State of North Carolina, during the period between 1992 and 1998. Controls (N=3404) were randomly selected from all live births for the same 7-year period. Logistic regression was used to model the association between race and pregnancy-related death. RESULTS: The unadjusted odds ratio (OR) for pregnancy-related death for African-Americans compared with Caucasians was 3.07 (95% confidence interval [CI], 2.08, 4.54). After controlling for gestational age at delivery, maternal age, income, hypertension, and receipt of prenatal care, African-American race remained a significant predictor variable (OR 2.65 [95% CI 1.73, 4.07]). CONCLUSIONS: Our analysis confirms that there is a strong association between race and pregnancy-related death, even after adjusting for potential predictors and confounders.

OBJECTIVE: To examine the association between health care services variables and pregnancy-related death using a contemporary geographically defined population and enhanced methods for case identification. METHODS: This is a population-based, case-control study from North Carolina for the 7-year period 1992-1998. Pregnancy-related deaths after a live birth (n = 118) were identified after review of pregnancy-associated deaths (n = 400) ascertained from death certificate codes and linkage of birth and death files. Controls (n = 3697) were randomly selected from all registered live births for the same 7-year period and were not matched with cases. This sample size was sufficient to ensure that the standard errors for subgroup prevalences were less than 1%. The associations between pregnancy-related death and health care services were explored with univariate and multivariable regression analysis. RESULTS: Neither maternity care coordination nor nutritional services were protective. There was no association with source of care, private versus public. The adjusted odds ratio (OR) for pregnancy-related death associated with cesarean delivery was 3.9 (95% confidence interval [CI] 2.5, 6.1). The adjusted OR for pregnancy-related death associated with the receipt of prenatal care was 0.2 (95% CI 0.1, 0.6). CONCLUSION: Removing barriers to and actively promoting use of prenatal care services and decreasing the rate of cesarean deliveries could decrease the number of pregnancy-related deaths.
