Effects of pre-pregnancy body mass index and gestational weight gain on maternal and infant complications.

ABSTRACT: BACKGROUND:The potential effects of pre-pregnancy body mass (BMI) and gestational weight gain (GWG) on pregnancy outcomes remain unclear. Thus, we investigated socio-demographic characteristics that affect pre-pregnancy BMIs and GWG and the effects of pre-pregnancy BMI and GWG on Chinese maternal and infant complications. METHODS:3172 women were enrolled in the Chinese Pregnant Women Cohort Study-Peking Union Medical College from July 25, 2017 to July 24, 2018, whose babies were delivered before December 31, 2018. Regression analysis was employed to evaluate the socio-demographic characteristics affecting pre-pregnancy BMI and GWG values and their effects on adverse maternal and infant complications. RESULTS:Multivariate logistic regression analysis revealed that age groups ?25?years old educated below university and college levels, for ethnic minorities and those women who live in the north of China. TRIAL REGISTRATION:Registered at Clinical Trials ( NCT03403543 ), September 29, 2017.
