Antenatal hospitalization among enlisted servicewomen, 1987-1990

Abstract

Objective: To describe the prevalence of, and indications for, antenatal hospitalization among women who delivered live and stillborn infants.

Methods: We reviewed the records of a cohort of 1825 black and white enlisted women who delivered from 1987-1990 at the four largest Army medical centers in the United States. Women with multiple gestations and those whose pregnancies ended before 20 weeks' gestation were excluded. Records of all women with preterm deliveries and a one-third sample of women with term deliveries were abstracted.

Results: Overall, 26.8 +/- 1.6% (mean +/- standard error) of the women were hospitalized antenatally. Of the estimated 702 antenatal hospitalizations, 44.0 +/- 3.4% were related to preterm labor, 10.3 +/- 1.9% to preeclampsia, 5.5 +/- 1.5% to hyperemesis, and 4.7 +/- 1.5% to urinary tract or kidney infection. The prevalence of hospitalization was lowest before 20 weeks (5.0 +/- 0.8%) and highest at 33-36 weeks (12.2 +/- 1.2%). Small and probably clinically insignificant differences between black and white women were noted in the overall prevalence of antenatal hospitalization and in the indications for hospitalization.

Conclusion: As measured by hospitalization, severe antenatal morbidity is common in this population of healthy enlisted women.
