The percentage of women who had a emergency cesarean section, stratified according to gestational weight gain ≥18 and <18 kg (emergency cesarean section vs. vaginal delivery): <18 kg (12.3 vs. 87.7), ≥18 kg (17.8 vs. 82.2). The women with weight gain ≥18 kg had a significantly increased risk of emergency cesarean section (P=0.005). BMI, body mass index.

The percentage of women who had emergency cesarean section, stratified according to gestational weight gain (emergency cesarean section vs. vaginal delivery): total (13 vs. 87), inadequate (12.6 vs. 87.4), adequate (12.6 vs. 87.4), excessive (14.2 vs. 85.8). The risk of emergency cesarean section had no significant differences between each groups (P=0.36). IOM, Institute of Medicine.
