TABLE 2—

Pregnancy-Related Mortality Ratios (PRMRs) and Percentage of Pregnancy-Related Mortality Cases Attributable to Black–White Differences in Prevalence and Case-Fatality Rates for 5 Selected Pregnancy Complications, by Race: United States, 1988–1999

	Deaths, No.		PRMRa
	Black	White	Black	White	Black–White Ratio of PRMRs	Cases Attributable to Difference in Prevalence, %	Cases Attributable to Difference in Case-Fatality Rates, %
Preeclampsia	177	261	2.334	0.700	3.3	18	82
Eclampsia	153	193	2.017	0.517	3.9	34	66
Abruption	43	71	0.567	0.190	3.0	7	93
Placenta previa	14	28	0.185	0.075	2.5	5	95
Postpartum hemorrhage	74	148	0.976	0.397	2.5	0	100

^aPRMRs were calculated as the number of pregnancy-related deaths from each of the selected conditions (obtained from the Pregnancy Mortality Surveillance System) per 100 000 live births (obtained from National Center for Health Statistics natality files).
