Table 1.

Demographic and clinical characteristics of study subjects in the 4 growth groups. Values in table are presented as mean ± SD or n (%). Legend: FGD = fetal growth deceleration; RPWG = rapid postnatal weight gain; ppBMI = pre-pregnancy body mass index; FPG = fasting plasma glucose; SGA = small-for-gestational-age; AGA = appropriate-for-gestational-age; LGA = large-for-gestational-age
