Trends and Characteristics of Self-reported Case Presentation of Diabetes Diagnosis Among Youth From 2002 to 2010: Findings From the SEARCH for Diabetes in Youth Study

Diagnosis of diabetes in youth is increasing in the U.S. (1,2). It is not known how much of this change is due to an increase in diabetes and how much is due to improved case detection, especially for type 2 diabetes. Some researchers have hypothesized that part of the explanation for the increase in diabetes diagnosis in youth is increased screening, resulting in a higher percentage of cases being identified. The objective of this study was to assess whether the change in diabetes could be explained by changes in case identification by examining trends from 2002 to 2010 in self-reported case presentation of diabetes.Briefly, there were 9,054 youth aged <20 years with newly diagnosed diabetes between 2002 and 2010 in the SEARCH for Diabetes in Youth study (3). Participants were asked, “How did you find out you had diabetes?” Responses were grouped into symptoms, checkup, community screening, or other. Self-reported case presentation patterns were examined in 3-year blocks to assess change over time, reported by diabetes type. We explored trends in self-reported modes of diabetes diagnosis (i.e., symptoms, checkup, screening, and other …
