  • Data are incidence percent per year (95% CI), age and sex standardized to the 1998 Australian population.

  • *

    * Men versus women. P value derived in age-adjusted models using logistic regression.

  • The population at risk of developing IFG were those with normal glycemia at baseline.

  • The population at risk of developing IGT were those with IFG or normal glycemia at baseline.
