Association of maternal prepregnancy BMI with metabolomic profile across gestation

Elevated prepregnancy body mass index (pBMI) and excess gestational weight gain (GWG) constitute important prenatal exposures that may program adiposity and disease risk in offspring. The objective of this study is to investigate the influence of pBMI and GWG on the maternal metabolomic profile across pregnancy, and to identify associations with birth weight. This is a longitudinal prospective study of 167 nondiabetic women carrying a singleton...
