Glycemic Level Modifies the Relationship Between Maternal Gestational Weight Gain and Neonatal Birth Weight in Type 2 Diabetes-Complicated Pregnancies.

ABSTRACT:

Objective

To examine whether glycemic level modifies the association between gestational weight gain (GWG) and pregnancy outcomes in type 2 diabetes-complicated pregnancies.

Research design and methods

This multicenter retrospective study stratified 1,642 pregnant women with diabetes by third-trimester glycemic control. Associations between excessive GWG (eGWG) and pregnancy outcomes were analyzed by group.

Results

Although birth weight and odds of macrosomia and cesarean delivery were higher for all women with eGWG relative to those with adequate GWG, the effect estimates for birth weight and macrosomia were significantly higher with suboptimal glycemic control compared with optimal control (birth weight increase: 361.04 vs. 126.07 g, respectively, P = 0.007; adjuste
