Abstract: Objective: To analyzed the current status of responsibility sharing for health management among adolescents with Type 1 Diabetes Mellitus (T1DM) and its associations with self-management behaviors and glycemic control, aiming to provide references for developing personalized family interventions and optimize the health management models. Methods: A convenience sampling method was employed to select 190 adolescents with T1DM attending routine follow-ups at two tertiary hospitals in Wenzhou and Suzhou from January to September, 2024. Data were collected using a general information questionnaire, the Diabetes Family Responsibility Questionnaire, and the Diabetes Self-care Activities scale. Stratified regression analysis was conducted to examine the impact of responsibility sharing on self-management behaviors and glycemic control levels. Results: In the health management of adolescents with T1DM, parental responsibility accounted for the highest proportion, at 42% (21%, 59%) of total responsibility. Regression analysis results revealed that, after controlling for demographic variables, shared responsibility independently explained 16.4% of the variance in patients' self-management behaviors and 5.3% of the variance in glycemic control. Parental responsibility independently explained 9.2% of the variance in self-management behaviors and 3.4% of the variance in glycemic control. Conclusion: The level of responsibility sharing in health management between adolescents with T1DM and their parents require enhancement. Optimizing the responsibility-sharing model may promote self-management behaviors and glycemic outcomes.
