Data, Surveillance, and Epidemiology

Graph showing the percent of adults diagnosed with diabetes, Montana and US. Graph shows the increasing trend of diagnosed diabetes in both the US* and MT**. The US rate is higher than MT with a trend from 7.0% in 2004 to 9.7% in 2014. MT increased from 6.0% in 2004 to 8.8% in 2014. Data source: Behavioral Risk Factor Surveillance System. *Nationwide (States and DC). National data for 2014 are not available. **Due to changes in survey methodology, starting in 2011, estimates can no longer be compared to estimates from previous years. All years going forward from 2011 can be compared to one another.

How common is diabetes and prediabetes?

Diabetes

  • About 65,000 Montana adults currently have diagnosed diabetes.1
  • The percentage of Montana adults with diagnosed diabetes increased from 2.8% in 1990 to 8.0% in 2016.1
  • Diabetes is more common among American Indians/Alaska Natives than White non-Hispanics in Montana. In 2015, 19.0% of American Indian/Alaska Natives in Montana reporting having diagnosed diabetes compared to 7.3% of White non-Hispanics.1
  • In the US, the number of people diagnosed with diabetes increased from 1.5 million in 1958 to 21 million in 2012.3

Prediabetes

  • In 2013, only 6.8% of Montana adults reported having pre-diabetes.1
  • However, data from a national survey suggests that the prevalence of pre-diabetes is 38%. Based on this, it is estimated that 300,000 Montana adults have pre-diabetes.2
  • In the US, it is estimated that 86 million people have pre-diabetes.3

What data sources inform us about pre-diabetes and diabetes?

The Montana Diabetes Program uses variety of data for diabetes surveillance and evaluation, reports, grant reporting, and to direct program decisions to reduce the prevalence of diabetes, the morbidity from diabetes, and the development of complications of diabetes among Montana residents. A list of data sets used is included below, and you can access the Public Health Data Resource Guide to learn more about them. Data sets do not contain information that can identify individuals.

  • Behavioral Risk Factor Surveillance System (BRFSS)
  • Birth and Death Records
  • Montana Hospital and Emergency Department Discharge Data System
  • Diabetes Quality Care Monitoring System (DQCMS)
    • The DQCMS is a diabetes patient registry to support quality improvement (QI) in primary care and diabetes self-management education programs. This program tracks outcomes for diabetes management including A1C, blood pressure, cholesterol levels, tobacco cessation, immunizations, chronic kidney disease, foot care, and medication. See the quarterly QI reports for more information.
  • Centers for Disease Control and Prevention (CDC)
  • Centers for Medicare and Medicaid (CMS)
    • The CMS provides information on the prevalence, utilization, and Medicare spending for beneficiaries with chronic conditions, including diabetes. The agency produced the Medicare Chronic Conditions Dashboard where data can be viewed by region, state and county.
  • American Diabetes Association (ADA)

Surveillance Reports

These reports aim to increase the understanding of data related to diabetes prevention, education, and management as well as provides clinical recommendation to the health care community.

Special Reports and Presentations

The Montana Diabetes Program staff often participate in regional and national conferences and share data related to diabetes and its complications in oral and poster presentations.  These reports and presentation cover variety of topics related to diabetes. Please contact the MDP to inquire about what other data may be available.
