Abstract

Background: Pre-pregnancy weight and gestational weight gain (GWG) are important factors in both maternal and infant outcomes. Little information is available in relation to different levels of pre-pregnancy body mass index (BMI) and body weight gain on obstetric outcomes in Taiwan. This study investigated the associations between pregnancy complications with pre-pregnant BMI and GWG, in Taiwanese women. Methods: Data were extracted from a delivery room information bank on all women delivering singleton babies in a medical center. Eight hundred and sixty pregnant women were included. The collected variables included basic information, GWG, and pregnancy and neonatal outcomes. Pregnant women were categorized according to their pre-pregnant BMI and GWG to evaluate the impacts of pre-pregnant BMI and maternal weight gain on the risk of pregnancy complications. Univariate and multivariable logistic regression analyses were performed, and odds ratios were calculated. Results: Pre-pregnancy BMI=24 kg/m2 increased the risks of gestational diabetes mellitus, preeclampsia, and preterm labor. Preeclampsia and Cesarean delivery were positively associated with high weight gains (>18 kg), whereas a low birth weight and preterm labor were strongly associated with low weight gains (14 kg in women who were underweight and normal weight before pregnancy. Conclusion: An appropriate maternal BMI (18.5-24 kg/m2) at conception followed by a suitable gestational weight gain (10-14 kg) has substantial impact on the overall health of pregnant women and would lead to better obstetric management for Taiwanese women.
