Wang X, et al. - In this investigation involving 71,892 children born at Kaiser Permanente Southern California hospitals in 2007 to 2011 with complete information on maternal risk factors, researchers identified latent BMI growth trajectories from ages 2 to 6 years and analyzed their independent connections with maternal prepregnancy obesity or overweight, preexisting T1D or T2D or gestational diabetes (GDM) with or without requiring antidiabetic medications during pregnancy, excessive gestational weight gain (EGWG), and breastfeeding ≤ 6 months. Findings suggested an association of child's high and increasing BMI trajectory strongly with maternal prepregnancy obesity and overweight, modestly with maternal T1D, T2D, and GDM requiring medication treatment and EGWG, and slightly with breastfeeding ≤ 6 months. There was little connection between GDM which did not require treatment during pregnancy.
