GDM gestational diabetes mellitus, IOM Institute of Medicine. 1 Pre-pregnancy BMI categories (kg/m2) are based on weight measured at earliest first trimester prenatal visit: normal (18.5–24.9); overweight (25.0–29.9); obese (30 or greater)
2Gestational weight gain by IOM guidelines: normal BMI (11.3–15.9 kgs); overweight (6.8–11.3 kgs); obese (5–7.3 kgs)
3Weekly rate of weight gain (kg/week) by BMI category: normal [0.5 (0.4–0.5)]; overweight [0.3 (0.2–0.3)]; obese: [0.2 (0.2–0.3)]
