626-P: Insulin Dosing Strategies Surrounding Food Intake among Older Adults with Type 1 Diabetes (T1D)

Introduction mean age 71.3±4.1 yrs; mean diabetes duration 33.5±18.1yrs; mean HbA1c 6.8±1.1; mean BMI 27.3±4.70]. Most older adults endorsed counting carbohydrates (CHO), checking glucose before eating, and eating in approximately the same way every day, while few endorsed using CHO exchanges, phone apps, or following a pre-specified meal plan. Education, sex, and age were associated with several strategies; mean HbA1c and BMI were significantly higher among those who did not count CHO (Figure). Conclusion: Older adults with T1D utilize varying strategies to dose insulin. Understanding factors underlying preferences may enable better matching of adults with acceptable and effective methods for managing T1D and diet. Disclosure A. Kahkoska: None. J. Sprinkles: None.
