  • Data are OR (95% CI). Model I, adjusted for the variables used in estimating 90th percentiles; model II, adjusted for field center, age, BMI, height, parity, smoking, alcohol use, hospitalization prior to delivery, any family history of diabetes, mean arterial blood pressure, and gestational age at OGTT.

  • *

    * Continuous variable analysis, glucose higher by 1 SD (0.4 mmol/l for FPG, 1.7 mmol/l for 1-h plasma glucose, and 1.3 mmol/l for 2-h plasma glucose).

  • Defined based on sex, ethnicity, field center, gestational age (36–44 weeks only), and parity.
