1626-P: Changes in Material Need Insecurities and Their Association with Disordered Eating in Youth and Young Adults with Type 1 Diabetes

Introduction and Objective: Disordered eating (DE) affects ~18-40% of youth and young adults (YYA) with type 1 diabetes (T1D) and can hinder effective diabetes care. While food insecurity is linked to DE, other material-need insecurities (MNI) remain understudied. We examined how patterns of change in MNI relate to DE in YYA with T1D. Methods: In 658 YYA with T1D (mean age: 23.3 years, range: 10-35) from the SEARCH Food Security Cohort study (2018-2022), four MNI domains (food, housing, transportation, and healthcare access) were assessed ~9 months apart. Four change patterns (persistent security, decreased insecurity, increased insecurity, and persistent insecurity) were identified for each MNI domain and their composite score. Associations between MNI patterns and DE scores from the Diabetes Eating Problem Survey-Revised (DEPS-R) were evaluated with adjusted generalized linear models. Results: Whereas 54.4% of YYA experienced no MNI at either time point, composite MNI status decreased in 12.9%, increased in 9.3%, and 23.3% faced persistent MNI. Mean DEPS-R scores increased consistently across MNI patterns and model estimates confirmed these associations (Table 1). Conclusion: Persistent and increasing MNIs were linked to higher DE scores, underscoring the psychosocial toll of social adversity. Screening and supportive services may help address these challenges in YYA with T1D. Disclosure S. Sultana: None. E.F. Julceus: None. J.A. Mendoza: None. T. Bekelman: None. K. Flory: None. A.
