Prediabetes Increased Among U.S. Youths From 1999 Through 2018 Regardless Of BMI

The prevalence of prediabetes among youth ages 12 to 19 in the United States increased from 11.6% in 1999 to 28.2% in 2018. The increase in prediabetes occurred across groups regardless of body mass index (BMI), and in each population demographic and socio-economic subgroup measured. Parental education level was not protective against the increase in prediabetes, but family income had a slight relationship to prevalence of prediabetes among youth.

Prediabetes is defined as having no recorded diagnosis of diabetes, but having a hemoglobin A1c level of 5.7% to 6.4%, or a fasting plasma glucose level . . .
