Prolong sitting had a statistically significant correlation with BMI ( CONCLUSION: The findings of the present study emphasize the importance of reducing sedentary time, promoting strength training and enhancing sleep quality in T2DM management. Targeted interventions in these areas can help improve health outcomes and quality of life for T2DM patients.
