摘要


Background and Objectives: This study explored the appropriate classification of pre-pregnancy body mass index (BMI) in women of childbearing age in Beijing, China. Methods and Study Design: Women with singleton pregnancies at more than 28 gestational weeks were retrospectively reviewed. Based on the pre-pregnancy BMI (kg/m^2), these patients were divided into 7 groups: <18.5, ≥18.5-22.9, ≥23-23.9, ≥24-24.9, ≥25-27.9, ≥28-29.9, and ≥30. Pregnancy adverse outcomes, including gestational hypertension with or without preeclampsia, gestational diabetes mellitus, initial cesarean section, postpartum hemorrhage, macrosomia, large-for-gestational age infant and so on were recorded. Binary logistic regression analysis was used to calculate the uncorrected and corrected odds ratios and 95% confidence intervals, with the ≥18.5-22.9 group serving as a reference. Results: A total of 11,136 pregnant women were analyzed. Incidences of above mentioned six adverse outcomes were greater in women with higher pre-pregnancy BMI. The risks of the abovementioned six adverse outcomes were increased significantly among the ≥23-23.9, ≥24-24.9, ≥25-27.9 groups and substantially higher in the ≥28-29.9, ≥30 groups after correction. <18.5 group showed an increased risk of small-for-gestational age infants. Conclusions: For women of childbearing age in Beijing, China, the optimal pre-pregnancy BMI range was ≥18.5-22.9 kg/m^2, with the cutoff value for overweight status being ≥23.0 kg/m^2 and the cutoff value for obesity being ≥28.0 kg/m^2.
