  • * Analysis excludes offspring of five insulin-treated mothers with GDM.

  • P values are from likelihood ratio tests for importance of the entire set of quartile indicator variables.

  • Adjusted P values for associations with metabolic measures are calculated using logistic regression models controlling for maternal and paternal obesity.
