Data are presented as the mean ± standard deviation (SD). BMI- body mass index; GWG- gestational weight gain. * based on the participants’ weight measured at childbirth. † 2009 Institute of Medicine (IOM) Recommendations for gestational weight gain during pregnancy: BMI < 19.8 kg/m2 total weight gain between 12.5 and 18 kg; BMI = 19.8 to 26.0 kg/m2 total weight gain between 11.5 and 16 kg; BMI > 26.0 to 29.0 kg/m2 total weight gain between 7.0 and 11.5 kg. For BMI > 29.0 kg/m2, total weight gain of 7.0 kg [6].
