668-P: Examining the Diabetes Management Questionnaire among Racially Minoritized Youth with Type 1 Diabetes

Introduction: Type 1 diabetes (T1D) racialized health inequities have resulted from centuries of racial oppression and discriminatory policies. Racially minoritized families report higher T1D adherence but worse HbA1c outcomes than non-Hispanic white families. The Diabetes Management Questionnaire (DMQ) is a measure of T1D adherence, normed in a primarily white, higher-class sample, where there were several demographic/medical correlates of the DMQ (see Table 1 Column C). We examined correlates of the DMQ in a racially minoritized sample. Methods: Fifty-seven youth aged 10-15 years who reported 75% continuous glucose monitor (CGM) use and their caregivers completed the DMQ. Associations between variables were analyzed using correlations or t-tests (child and caregiver report; Column B). Results: HbA1c was a measure of DMQ predictive validity in the original sample, but not in our sample (Column D). Conclusion: Racialized health inequities contribute to differences between the two samples. The DMQ may have weaker psychometric properties in racially minoritized youth; factors due to structural racism e.g., racial residential segregation may be more germane to HbA1c than individual T1D management behaviors. The two samples also had different characteristics e.g., T1D technology use, HbA1c outcomes, caregiver education, insurance type, age, sampling methods/size, geographic locations. Disclosure E.
