Applied Research and Surveillance

Applied research includes observational and clinical epidemiologic studies, health services research, and economic studies designed to:

  • Identify modifiable risk factors.
  • Determine the effectiveness of interventions at individual, health care system, community, and policy levels.
  • Prioritize the value of successful interventions.

Surveillance involves the development and use of systems to collect and analyze data to:

  • Identify the burden and magnitude of diabetes and its related conditions.
  • Guide decision making.
  • Prioritize national public health objectives.
  • Evaluate the impact of diabetes prevention programs.

Applied Research Projects

Novel Approaches to State-level Diabetes and Prediabetes Surveillance

Overall Objective: CDC works with state health departments to track diabetes prevalence, control of diabetes risk factors such as prediabetes, and control of key indicators such as hemoglobin A1c, blood pressure, and cholesterol.  However, it is difficult to estimate diabetes prevalence (including undiagnosed cases), prediabetes, and related health problems at the state level.  This Website Novel Approaches to State-level Diabetes and Prediabetes Surveillance examines the feasibility of using a variety of data sources in novel ways to address this challenge.

Funding Agencies:

  • CDC, National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP), DDT

Period of Funding: September 30, 2014 to September 29, 2017

Contractors:

  • Westat, Inc.

Longitudinal Epidemiologic Assessment of Diabetes Risk (LEADR)

Overall Objective: This project uses electronic health records from DARTnet, a collaboration of practice-based research networks, to assess risk factors and incidence of type 2 diabetes. It will also examine how often people at high risk of developing type 2 diabetes receive counseling and are referred to diabetes prevention programs. Other objectives of this project include the following:

  • Establish a population-based cohort using electronic records to identify traditional and emerging risk factors for type 2 diabetes.
  • Assess the availability, delivery, and impact of type 2 diabetes preventive care.
  • Develop and test strategies for identifying people at risk of developing type 2 diabetes.

Funding Agencies:

  • CDC, National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP), DDT

Period of Funding: 09/29/2015–09/28/2020

Contractors:

  • Westat (contract # HHSD200201587699) and its subcontractor
  • DARTnet Institute

Population-based Diabetes in Youth Registry, the SEARCH for Diabetes in Youth Study

Overall Objective: This project monitors how many children and adolescents in the United States are affected by diabetes and whether the occurrence of the disease is increasing over time. Each year, SEARCH (the SEARCH for Diabetes in Youth study) conducts surveillance on about 5 million children to estimate the number of new cases of diabetes. This study also collects data on diabetes complications, risk factors for diabetes complications, and the quality of care and the quality of life of children and adolescents with diabetes.

In 2009, SEARCH estimated that 167,000 youth (younger than 20 years) in the United States had type 1 diabetes, an increase of over 21% from 2001. From 2002 through 2009, the annual rate of new cases among non-Hispanic white youth increased by 2.7% each year. SEARCH also estimated that 20,300 US youth had type 2 diabetes in 2009, an increase of over 30% from 2001. This study has also shown that diabetes complications are present at an early age, and complications are more common among minority youth, and those with type 2 diabetes.
