The morbidity and mortality of pregnancy: still risky business.

Despite impressive gains in safety in recent decades, pregnancy remains risky business. From early in pregnancy until some weeks after its conclusion, pregnant women are at increased risk of morbidity and mortality compared with women who are not pregnant. This review summarizes recent national data from the U.S. Centers for Disease Control and Prevention, including vital statistics from the National Center for Health Statistics. Ectopic pregnancy is substantially more dangerous (38 deaths/100,000 events) than either childbirth (nine) or legal abortion (less than one). The three leading causes of maternal death today are pregnancy-induced hypertension, hemorrhage, and pulmonary embolism. Although comprehensive data on pregnancy-related morbidity are lacking, about 22% of all pregnant women are hospitalized before delivery because of complications. Women of minority races have much higher risks of death than do white women, and the same holds true for older women and those with limited education. For most women, fertility regulation by contraception, sterilization, or legal abortion is substantially safer than childbirth.
