The Association of Maternal Body Mass Index with Birth Weight and Cesarean Delivery / 대한산부인과학회잡지

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate the correlations of pre-pregnancy maternal BMI(body mass index), and weight gain during pregnancy with Birth weight and Cesarean delivery in full term infants. METHODS: We collected data from 1086 pregnancies without complications, and analysed pre-pregnancy maternal BMI, weight gain during pregnancy, and the incidences of SGA(small-for-gestational age), LGA(large-for-gestational age), cesarean delivery. Chi-square test, T-test, and One way Anova test were performed for stastatical analysis. RESULTS: In pre-pregnancy maternal BMI 26.0kg/m2 group, 0%, 23.6% and 36.4% respectively(p<0.05). In under weight gain during pregnancy group, incidence of SGA was 13.4%, LGA 4.7% and cesarean delivery 15.7% respectively, but in high weight gain group, 4.8%, 19.5% and 21.0% respectively(p<0.05). CONCLUSION: There was significant correlations among pre-pregnancy maternal BMI, weight gain during pregnancy, birth weight and cesarean delivery. From these results, it is considered that antenatal maternal BMI and weight gain during pregnancy are valuable to predict birth weight and cesarean delivery.
