631-P: Youth with Type 1 Diabetes (T1D) and High Social Risk: Predictors of Glycemic Control

Objective: A subset of youth with T1D experience ongoing challenges with diabetes self-management, often due to social risk. This 5-site study examined which social factors were associated with hemoglobin A1c (A1c) , specifically in youth with preexisting high A1c. Methods: Youth with T1D for more than 1 year were included if between 12-17 years old and with at least one A1c value ≥10% in the past year. Chart review captured A1c values, and caregivers reported on social risk- with 16 risk variables (e.g., housing security, employment status) in initial analyses. Multivariable linear regression model included A1c from 1 year prior to enrollment as an outcome and backwards stepwise procedure retained covariates with p Results: Participants (n=130) had a mean age of 14.4 (±1.6) years and mean A1c of 11.1 (±1.7) ; 49% reported male gender; 51% self-identified as Non-Hispanic White. A1c prior to study enrollment was predicted to be 0.68 lower in individuals whose caregiver had at least a college education and 0.65 higher when caregivers were divorced or separated. Conclusion: Findings suggest that, in youth with preexisting difficulty with glycemic variability, caregiver education level and marital status are associated with A1c - and, while not causal, may reflect unique value when screening for risk. This cohort will be followed to determine which factors predict future health concerns and associated need for intervention. Disclosure D.V.Wagner: None. L.Yglecias: None. J.J.Flores garcia: None.
