Risk factors for pre‐eclampsia in an Asian population

Abstract
Objective: To identify the risk factors for pre‐eclampsia in an Asian population. Method: We conducted a retrospective cohort study involving 29 375 Taiwanese women who delivered between July 1990 and September 1998, excluding pregnancies complicated by chronic hypertension or fetal malformations. Result: Four hundred and fifteen women had pre‐eclampsia (1.4%). Women who had a history of pre‐eclampsia (OR 6.3, 95% CI 4.4, 9.2), multiple gestation (OR 3.6, 95% CI 2.4, 5.5), a prepregnancy BMI>24.2 kg/m2 (OR 2.4, 95% CI 1.8, 3.1), were>34 years of age (OR 1.8, 95% CI 1.4, 2.4), nulliparous (OR 1.3, 95% CI 1.2, 1.5), had urinary tract infection (OR 4.8, 95% CI 1.5, 15.8), or worked during pregnancy (OR 1.9, 95% CI 1.4, 2.4) were at increased risk of pre‐eclampsia. Conclusion: Some of the risk factors for pre‐eclampsia among Asian women are the same as those of other ethnic groups, whereas some of the risk factors are different.
