  • Data are n (%).

  • *

    * All categories based on standardized measures; birth weight standardized for gestational age and sex, BMI standardized for sex. Data restricted to participants with information from age under investigation and on BMI at 23 years of age. Data for participants with diabetes restricted to measurements obtained before the reported age at onset.

  • Number of diabetic subjects presented in parentheses. Sex-specific cutoff points for the 33rd and 66th centiles. Standardized birth weight −0.34, 0.45; BMI at 7 years: 15.3, 16.3; BMI at 11 years: 16.1, 17.6; BMI at 16 years: 19.0, 20.7; BMI at 23 years: 21.8, 23.8. Females: Standardized birth weight −0.37, 0.42; BMI at 7 years: 15.0, 16.3; BMI at 11 years: 16.2, 18.1; BMI at 16 years: 19.6, 21.7; BMI at 23 years: 20.4, 22.5.
