Diagnosed Pre-diabetes Prevalence by Year, New Mexico and U.S., Age-adjusted, 2011 to 2020

Why Is This Important?

People with pre-diabetes have blood glucose levels higher than normal, but not high enough to be diagnosed as diabetes. The Centers for Disease Control and Prevention (CDC) states that without weight loss and physical activity, 15-30% of adults with pre-diabetes will develop diabetes within five years. People with pre-diabetes are also more likely to develop heart disease and stroke. It is very important that adults at risk of pre-diabetes be tested as there is great value in the ability to take action as early as possible. People who are diagnosed with pre-diabetes can learn about their condition and build the skills and confidence necessary to slow or prevent progression to diabetes. The U.S. Preventive Services Task Force (USPSTF) recommends screening for prediabetes and type 2 diabetes in adults ages 35 to 70 years who are overweight or have obesity. USPSTF notes that clinicians should offer or refer people with prediabetes to effective preventive interventions. USPSTF found convincing evidence that preventive interventions for people with prediabetes have a moderate benefit in reducing progression to type 2 diabetes. They also found adequate evidence that interventions for people with newly diagnosed diabetes have a moderate benefit in reducing the risk of death. (https://health.gov/healthypeople/tools-action/browse-evidence-based-resources/screening-prediabetes-and-type-2-diabetes) It is important to keep in mind that there is reason to believe that pre-diabetes is dramatically under-diagnosed. Consequently, estimates of diagnosed pre-diabetes may not reflect the true prevalence of pre-diabetes.

The prevalence of diagnosed pre-diabetes was statistically significantly higher in the years 2017 through 2020, than all years prior to 2016. As pre-diabetes continues to be under-diagnosed, the increase in prevalence may be due to a true increase in the prevalence of pre-diabetes or simply an improvement in testing and diagnosis, or some combination of the two. The prevalence of diagnosed pre-diabetes in NM was similar to that of the U.S. through 2017 but was statistically significantly higher in 2018 through 2020.

Definition

Pre-diabetes prevalence is the estimated percentage of adult New Mexicans 18 years and older with diagnosed pre-diabetes. Age-adjusted to U.S. 2000 population (except for rates by age group).

Data Notes

  • Percentages have been age-adjusted using the direct method and the 2000 U.S. standard population.
  • Diagnosed Pre-diabetes prevalence for New Mexico and the U.S. is a weighted and age-adjusted percent.

Data Sources

  • Behavioral Risk Factor Surveillance System Survey Data, U.S. Department of Health and Human Services, Centers for Disease Control and Prevention, together with New Mexico Department of Health, Injury and Behavioral Epidemiology Bureau.

How the Measure is Calculated

Numerator:Number of New Mexico adults (18 and older) who either responded, "Yes" to the BRFSS question: "Have you ever been told by a doctor or other health professional that you have pre-diabetes or borderline diabetes?" OR responded "No, pre-diabetes or borderline diabetes" to the core Diabetes Prevalence question "Have you ever been told by a doctor or other health professional that you have diabetes?"
Denominator:Number of New Mexico adults (18 and older) who responded to the BRFSS within the survey year.

Data Issues

The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing survey of adults about health-related behaviors, health conditions, and preventive services. Data are collected in all 50 states, D.C., and U.S. territories. The survey is conducted using scientific telephone survey methods for landline and cellular phones (with cellular since 2011). The landline phone portion of the survey excludes adults living in group quarters such as college dormitories, nursing homes, military barracks, and prisons. The cellular phone portion of the survey includes adult students living in college dormitories but excludes other group quarters. Beginning with 2011, the BRFSS updated its surveillance methods by adding in calls to cell phones and changing its weighting methods. These changes improve BRFSS' ability to take into account the increasing proportion of U.S. adults using only cellular telephones. Because of these changes, the data from years prior to 2011 are not directly comparable to data from 2011 and later. Please see the [[a href="/nmibis-view/docs/Query/BRFSS/BRFSS_fact_sheet_Aug2012.pdf BRFSS Method Change Factsheet]]. Responses have been weighted to reflect the New Mexico adult population by age, sex, ethnicity, geographic region, marital status, education level, home ownership and type of phone. The "missing" and "don't know" responses are not included when calculating a percentage.
