Physical activity is a multidimensional behavior shaped by individual, interpersonal, institutional, community, and policy-level influences, and it plays a critical role in diabetes management, metabolic health, and overall well-being in youth with T1D.\n\nThe main questions it aims to answer are:\n\nDo factors at the individual, interpersonal, institutional, community, and policy levels of the Socio-Ecological Model significantly influence physical activity participation, social participation, and diabetes management in adolescents with Type 1 diabetes? Which modifiable barriers and facilitators at these multiple levels are associated with higher or lower levels of physical activity?\n\nParticipants diagnosed with Type 1 diabetes will complete questionnaires assessing their daily living activities, exercise habits, social participation, psychosocial characteristics, and perceived social and environmental support. Objective measurements related to circadian rhythm patterns and glycemic control will also be collected. The study will analyze how multilevel socio-ecological factors are associated with physical activity behavior, social engagement, and diabetes management outcomes.\n\nThe findings are expected to provide a comprehensive biopsychosocial understanding of physical activity behaviors in adolescents with Type 1 diabetes and to inform the development of supportive, school- and community-based intervention strategies aimed at improving quality of life, self-efficacy, psychological resilience, and sustainable participation in physical activity.",[85],"Type 1 Diabetes Mellitus",[87,88,89],"Type 1 diabetes mellitus","Socio-Ecological Model","Physical Activity","2026-04-28",{"date":92,"type":93},"2026-05-05","ACTUAL",{"date":95,"type":93},"2026-01-02",{"date":97,"type":80},"2026-09-13",{"name":5,"class":6},1]
