This study is a multicenter cross-sectional research project, planning to enroll 1000 patients with Type 1 Diabetes Mellitus (T1DM). By reviewing clinical data, physical examinations, questionnaires, continuous glucose monitoring, and subcutaneous fat ultrasound, we aim to understand the current status of treatment and metabolism in Chinese T1DM patients and analyze the potential factors that may affect their blood sugar control and metabolic indicators. A cost-effectiveness analysis will be conducted on Chinese T1DM patients using continuous glucose monitoring systems to identify the groups that benefit most from these systems.
