In collaboration with researchers from the New York City Department of Health and Mental Hygiene we recently published an article in the American Journal of Epidemiology showing that diabetics living in neighborhoods with more advantaged economic environments, greater walkability and healthier retail food environments have an improved ability to achieve glycemic control. Hemoglobin A1C data from the New York City A1C Registry for 182,756 adults who had 1,273,801 A1C tests from 2007 to 2013 were analyzed along with data describing the neighborhood contexts they lived in. The odds of individuals achieving glycemic control in the most advantaged residential neighborhoods (better economic conditions, greater walkability, healthier retail food profiles) was two and a half times greater than in the least advantaged. Furthermore, individuals who lived in the most advantaged residential neighborhoods achieved glycemic control in a shorter period of time than individuals who lived in the least advantaged neighborhoods. For those who moved during the 2007 to 2014 period, moving from less advantaged neighborhoods to more advantaged neighborhoods was associated with improved diabetes control, while moving from more advantaged areas to less advantaged areas was related to worsening diabetes control. This is the first longitudinal study to examine the relationship between residential neighborhood environments and individual’s ability to control their diabetes.
