About the trial

What the trial wants to find out

The goal of this observational study is to examine the multilevel factors influencing physical activity participation in adolescents with Type 1 diabetes (T1D) within the framework of the Socio-Ecological Model (SEM). 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.

The main questions it aims to answer are:

Do 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?

Participants 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.

The 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.

The group in the trial

Adolescents with Type 1 Diabetes
This cohort consists of adolescents aged 9-18 years diagnosed with Type 1 diabetes for at least one year and currently receiving regular medical follow-up in Istanbul. Participants meet predefined inclusion criteria, including documented HbA1c values ≥8% within the previous year and reported glycemic biomarkers. All participants use at least one glucose monitoring device and are capable of completing study questionnaires. This is an observational, cross-sectional study. No experimental intervention is applied. Participants will complete validated questionnaires assessing physical activity, daily living activities, social participation, psychosocial factors, and socio-ecological determinants. Objective measures related to glycemic control .
