Health Indicator Report of Diabetes (Diagnosed) Prevalence

Diabetes and its frequent precursor, prediabetes, are conditions on a continuum marked by high levels of blood glucose (blood sugar) due to defects in insulin production, insulin action, or both. Insulin is a hormone needed to absorb and use glucose as fuel for the body's cells. Diabetes can lower life expectancy and increase the risk of heart disease. It is the leading cause of kidney failure, lower limb amputation, and adult-onset blindness. Diabetes and its complications can often be prevented or delayed. People who are diagnosed with diabetes or prediabetes need to learn about their condition and build the skills and confidence necessary to successfully take care of themselves, with the help of their health care team and community resources. About one-quarter of people with diabetes don't know they have it, and most people with prediabetes don't know they have it. Unfortunately, people who are undiagnosed can't take steps to manage their condition. Data in this Profile are only about diagnosed diabetes prevalence.


All prevalence estimates are age-adjusted to the U.S. 2000 standard population (except for rates by age group).   **No data available in 2019.

Data Source

Behavioral Risk Factor Survey, Center for Health Statistics and Informatics, New Jersey Department of Health [] (Supported in part by the PHHS Block Grant, CDC Cooperative Agreement Number NB01OT009201)

Data Interpretation Issues

Data for this indicator report are from the Behavioral Risk Factor Surveillance System (BRFSS), an ongoing survey of adults regarding their health-related behaviors, health conditions, and preventive services. Data are collected in all 50 states, D.C., and U.S. territories. Responses have been weighted to reflect the New Jersey adult population by age, sex, ethnicity, geographic region, marital status, education level, home ownership and type of phone ownership. 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 adults, in general, as well as adult students living in college dormitories but excludes other group quarters. Beginning with 2011, the BRFSS updated its surveillance methods by adding calls to cell phones and changing its weighting methods. These changes improved the BRFSS' ability to take into account the increasing proportion of U.S. adults using only cellular telephones as well as to adjust survey data to improve the representativeness of the estimates generated from the survey. Results have been adjusted for the probability of selection of the respondent, and have been weighted to the adult population by age, gender, phone type, detailed race/ethnicity, renter/owner, education, marital status, and geographic area. The "missing" and "don't know" responses were removed before calculating a percentage.


Diabetes prevalence is the estimated percentage of New Jersey adults 18 years and older with diagnosed diabetes.


Number of adult (18 and older) New Jersey respondents who responded, "yes" (within the survey year) to the BRFSS question: "Has a doctor, nurse, or other health professional ever told you that you have diabetes?".


Number of New Jersey adults (18 and older) who responded to the BRFSS within the survey year.

Healthy People Objective: Increase the proportion of persons with diabetes whose condition has been diagnosed

U.S. Target: 80.1 percent

Other Objectives

There are 16 major Healthy People 2020 objectives for diabetes. Diabetes objectives D-5 to D-14 are about self-management and care behaviors among those with diagnosed diabetes. Objective D-15 is "Increase the proportion of people with diabetes whose condition has been diagnosed".

How Are We Doing?

In 2020, the age-adjusted prevalence of diagnosed diabetes in New Jersey was 8.5%. Hispanics (13.1), Asians (13.0%), and Blacks (11.5%) have a higher prevalence of diagnosed diabetes compared to Whites (6.3%).

How Do We Compare With the U.S.?

In 2020, New Jersey's age-adjusted rate of adults diagnosed with diabetes was slightly lower compared to U.S. age-adjusted rate (8.5 % vs. 10.0%).

What Is Being Done?

The Diabetes Prevention and Control Program (DPCP) approach to addressing diabetes in New Jersey is driven by population-based and evidence-based strategies to increase community-clinical linkages and clinical innovations to support the prevention and management of diabetes. The overall goal of the DPCP is to reduce the burden of diabetes on New Jersey residents by implementing community clinical linkages and health systems interventions that increase awareness of the disease, control disease related complications, and increase quality improvement processes in health systems, in the delivery of services to residents with diabetes. DPCP partners with organizations across the state to create Diabetes Resources Coordination Centers (DRCCs). These DRCCs liaise between community-based diabetes self-management education (DSME), diabetes prevention programs (DPP), and healthcare systems, to increase access to community-based programs, by helping providers establish referral policies and practices for diabetic patients. DPCP partners with NJ 2-1-1, the statewide non-emergency, information call center and website, to promote ADA-recognized, AADE-accredited and/or Stanford licensed diabetes self-management education, and lifestyle change workshops, and direct callers to increase utilization and access of these programs among New Jersey residents. NJ211 and the NJ Academy of Family Physicians also partners to leverage NJAFPs membership, through their statewide reach, to promote diabetes prevention and self-management resources to primary care providers. The Diabetes Prevention and Control Program collaborates with Department of Human Services (DHS) - Commission for the Blind and Visually Impaired (CBVI) - Diabetic Eye Disease Detection (DEDD) Program to increase access to free eye examinations for uninsured or underinsured residents with diabetes. To increase state capacity to prevent type 2 diabetes in adults, NJDOH teamed up with the New Jersey Hospital Association (NJHA) to build capacity in the state by offering free Lifestyle Change Coach trainings to health systems and organizations interested in adopting the National Diabetes Prevention Program (NDPP). The Diabetes Prevention and Control Program (DPCP) currently partners with 22 Federally Qualified Health Centers (FQHCs) to adopt evidence-based strategies for the enhancement of electronic health records and/or team-based care appropriate for treating patients with diabetes in healthcare systems. Finally, DPCP collaborates with Regional Planning Collaboratives to leverage new clinical decision support systems for management of patients with diabetes to determine if there is a significant and sustainable impact on diabetes control and prevention in their patient populations. Through their enhanced health information exchanges, the RPCs confidentially report National Quality Forum measures 18 and 59, medication adherence measures, and other quality measures among providers (and to NJDOH) to support quality improvement activities.

Evidence-based Practices

Successful strategies implemented for FQHC partners include interventions such as incorporating clinical guidelines that are a part of a decision support system; changing roles and adding new positions to enhance care coordination teams; and improving usability and applicability of alerts, order sets, registries, and other clinical data available through electronic health records (EHRs) and health information exchanges (HIEs)
