About the National Data
Data
Data Source: National Health Interview Survey (NHIS), CDC/NCHS
Baseline: 5.5 new cases of diabetes per 1,000 adults aged 18 to 84 years occurred in the past 12 months as reported in 2019-21
Target: 4.8 per 1,000
Methodology
Questions used to obtain the national baseline data
From the 2019 National Health Interview Survey:
Numerator:
[Not including (gestational diabetes, prediabetes)] Has a doctor or other health professional EVER told you that you had diabetes?- Yes
- No
- Refused
- Don't know
- 000 thru 120 Age at which diagnosed
- Refused
- Don't know
Methodology notes
Adults are considered to have diabetes if they respond "yes" to being told by a doctor or health professional that they have diabetes. Those who reported only "borderline" or only "prediabetes"are not included. Women who report that the only time they have been diagnosed with diabetes was during pregnancy (gestational diabetes) are also excluded. Diagnosed with diabetes in the past 12 months is determined by taking the difference of the reported age at diagnosis from the respondents reported age. All records with a difference of zero (same age) are included and half of the records with a difference value of one are included (to approximate the one year interval as the true time could be greater than one year depending on the birthday and the date of the interview). The measure uses a 3-year moving average to reliably report data for select population groups that have small sample sizes. Rates were age-adjusted to the 2000 US standard population using age groups: 18-44, 45-54, 55-64, 65-74, 75-84.

History
- Revised.
In 2022, due to the 2019 NHIS redesign and survey question changes. The baseline questions changed from, "[Other than during pregnancy], have you EVER been told by a doctor or health professional that you have diabetes or sugar diabetes?" and "How old were you when a doctor first told you that you had diabetes or sugar diabetes?" to "[Not including (gestational diabetes, prediabetes)] Has a doctor or other health professional EVER told you that you had diabetes?" and "How old were you when a doctor or other health professional FIRST told you that you had diabetes [not including prediabetes or
gestational diabetes]. The baseline was revised from 6.5 per 1,000 in 2016-2018 to 5.5 per 1,000 in 2019-2021. The target was revised from 5.6 per 1,000 to 4.8 per 1,000
using the original target setting method. - Revised.
In 2024, the following categories were recalculated with the use of a newer variable: Never married, American Indian or Alaska Native only, Native Hawaiian or Other Pacific Islander only, 2 or more races only, Not Hispanic or Latino American Indian or Alaska Native only, Not Hispanic or Latino Native Hawaiian or Other Pacific Islander only, Not Hispanic or Latino 2 or more races only. Estimates from data year 2022 or earlier may vary slightly from estimates previously reported. The baseline, baseline year and target were not affected.
