INS and gestational diabetes: In this study of 958 GDM women (485 treated vs. 473 no treatment), mean FM in infants of GDM mothers who received the treatment of diet therapy (n = 427) and insulin, if required (n = 36), was significantly lower (p = 0.003) than that of control infants whose mothers received usual prenatal care (427 ± 198 g vs. 464 ± 222 g).
