Geographic Access to Diabetes Prevention Program Sites: New York State Department of Health
The figure is an interactive map of New York State, divided into counties, with locations of existing (n = 39) and potential (n = 715) Diabetes Prevention Program (DPP) sites marked in each of the 62 counties. Counties are rendered in 3 different shades to indicate their prediabetes risk-factor score: lower risk (z-score, <0.13); at risk (z-score, 0.13–1.85); and highest risk (z-score, z≥1.85). Thirty-minute drive-time buffers are drawn around the 39 existing sites, showing that the population of several of the counties at highest risk are located outside the drive-time buffer. The map shows that the 39 existing DPP sites are located primarily in metropolitan areas and that every county has at least 1 potential DPP site. The map includes a scale of miles with 1 inch equivalent to 60 miles.
Map. This map displays existing and potential Diabetes Prevention Program sites in New York State, by county, 30-minute drive-time boundaries to existing sites, and prediabetes risk factor scores. Approximately 80.0% of New York’s population resides within a 30-minute drive time to a Diabetes Prevention Program site; however, most people living in 10 of the counties with the highest prediabetes risk-factor score live at a distance beyond a 30-minute drive to an existing site. Data sources: Source for prediabetes risk factor score: New York State Behavioral Risk Factor Surveillance System (1) and New York City Community Health Survey (2). Source for existing diabetes prevention program sites: New York City Department of Health and Mental Hygiene (3), New York State Department of Health (4), and Centers for Disease Control and Prevention (5). Source for potential program sites: Health Resources and Services Administration (6), New York Association for Independent Living (7,8), and New York State Office for the Aging (9).
