The effect of marital status on pregnancy outcome in Israel: a retrospective case-control study.

摘要

AIMS: Previous studies have observed an association between unmarried status of the mother and adverse perinatal outcome such as increased rate of preterm deliveries, low birthweight and small-for-gestational-age infants. In Israel, attendance of prenatal care is imposed by the state and is not related to socioeconomic status; therefore, unmarried women are expected to have a similar prenatal care as married women. The objective of this study is to test the hypothesis that unmarried and married pregnant women have a similar perinatal outcome. MATERIAL & METHODS: In a retrospective case-control study, analysis of the records of women who gave birth at the delivery ward of Edith Wolfson Medical Center (a tertiary health care center) over a one-year period (2005) with respect to marital status was performed. The cases group included 304 unmarried women who were matched with 1:1 ratio for maternal age, parity, and number of fetuses in the current pregnancy. RESULTS: Unmarried women (n = 304) were more likely to smoke during pregnancy (35.2% vs 15.2%, P < 0.001), had a longer second stage (44.4 +/- 9.8 min vs 54.4 +/- 4.4 min, P < 0.05) and a shorter first stage (484.0 +/- 34.8 min vs 421.0 +/- 25.3 min P < 0.05) of labor. The unmarried women had similar length of gestation, preterm delivery rate, mode of delivery, low birthweight rates, low Apgar scores or meconium passage during labor as married women. CONCLUSION: In Israel, unmarried and married pregnant women may have almost similar pregnancy outcomes on length of gestation, mode of delivery and Apgar score.
