  • Data are % (95% CI). Undiagnosed diabetes is defined as fasting plasma glucose ≥7.0 mmol/l. Values for the total population and for men and women include those of race/ethnic groups not listed separately. All CIs were logit transformed.

  • *

    * Standardized to the 2000 U.S. Census population by age and sex for the total population and race/ethnic groups and by age for sex-groups.

  • In the age 20- to 39-year group, there was no undiagnosed diabetes among 256 non-Hispanic white men and 400 Mexican Americans (186 men and 214 women) who were in the nondiabetic fasting morning sample.
