ORs for the dichotomous outcomes are for the continuous predictors higher by one SD estimated in the original HAPO data: fasting glucose 0.4 mmol/l; 1 h glucose 1.7 mmol/l; 2 h glucose 1.3 mmol/l; HbA1c 5.0 mmol/mol (0.45%). Models are adjusted for field centre for being overweight/obesity and IOTF obesity outcomes, child pubertal status (Tanner Stage 1, 2/3, 4/5), maternal variables during pregnancy OGTT (age, height, any family history of diabetes, mean arterial pressure, parity [0, 1+], smoking [yes/no], alcohol [yes/no], gestational age, maternal BMI during pregnancy
