PSUN92 Type 1 Diabetes and Obesity: The Overlooked Epidemic

INTRODUCTION: The type 1 diabetes (T1D) cohort in the DCCT study (1983-1989) began with a 1.3% prevalence of obesity that climbed to 18.6% with intensive insulin therapy, and subsequently increased further to a prevalence of 31% in the EDIC observational study (2005).1, 2 The aim of this report was determine the prevalence of overweight and obesity in T1D patients seen at our institution. METHODS: The electronic health record system was used to create a cross-sectional summary of patients with T1D seen on or before the index date (8/12/2021). Patients were included if they were ≥18 years of age, with at least two outpatient encounters with primary care provider or endocrinologist within the past 18 months, along with an active diagnosis of T1D (ICD-9 or -10 code) on their problem list, or at least 2 encounter diagnosis for T1D in the past 18 months, or documentation of a positive glutamic acid decarboxylase (GAD)-65 antibody titer. Categorical and continuous variables were summarized using N (%) and median (IQR), respectively. RESULTS: A total of 2,165 patients were identified. The population was 51% female and 86% Caucasian, with median age of 44 years (33, 55). The median A1C (%) was 7.9% (6.9, 9.4), median income $63,381 ($49,611, $78,367), and insurance coverage was 50% commercial, 11% Medicaid, 23% Medicare, and 16% other. While the median BMI (kg/m(2)) was 26.7 (23.6, 30.5), the % with a BMI 25-29.9 or ≥30 were 37% and 28%, respectively. CONCLUSION: There is a high prevalence of overweight and obesity in patients with T1D. While the prevalence of these comorbidities is less than what is observed in the general population, 31.1 and 42.4%, respectively (2017–2018)(3), it signifies that the T1D population still has a heavy burden of these comorbidities that is contradictive to the stereotype T1D patients are lean. These results stand in stark comparison with the starting 1.3% prevalence of obesity in the DCCT study. Studies directed at the burden of overweight and obesity in T1D patients are necessary to optimize the treatment and prevention of these comorbidities.
