Data are means (95% CI).
*Model 1 is adjusted for ethnicity, parity of the mother, and sex of the newborn.
†Model 2 is adjusted for ethnicity, parity of the mother, sex of the newborn, maternal age, BMI, smoking, family history of diabetes, gestational age at the OGTT, mean arterial blood pressure, and height.
