Prevalence of Diabetes Among US Adults

BMJ; ePub 2018 Aug 27; Xu, Liu, et al

Type 2 diabetes (T2D) accounts for >91% of all diabetes cases among US adults, with the prevalence of T2D at 8.5% of the population, a recent study found. The population-based study estimated the prevalence of diagnosed total diabetes, type 1 diabetes (T1D), and T2D, in the US general population and the proportions of each among US adults with a diagnosis of diabetes in 2016 and 2017. Adults aged ≥20 years (n=58,186) were included as a nationally representative sample of the civilian, non-institutionalized US population. Among the findings:

  • Among the 58,186 included adults, 6,317 had received a diagnosis of diabetes.
  • The prevalence of diagnosed T1D and T2D in 2016 and 2017 among US adults was 0.5% and 8.5%, respectively.
  • Among those with diabetes, the weighted percentage of T1D and T2D was 5.6% and 91.2%, respectively.
  • The percentage of T1D was higher among younger adults, non-Hispanic whites, those with higher education level, and those with lower body mass index (BMI).
  • The percentage of T2D was higher among older adults, non-Hispanic Asians, those with lower education level, and those with higher BMI.
