Primary Outcome Measures

Name	Time	Method
Effects of structured education on β-cell endocrine function progression of T1D patients.	Baseline and every three months afterwards.	The natural progression of patients' β-cell endocrine functions was assessed by fasting C-peptide (FCP) and postprandial C-peptide (PCP) at each visit. FCP and PCP levels were measured at initial recruitment and every three months after that. The decay rate of β-cell endocrine function of patients in the two groups were compared.; Serum C-peptide levels were measured by a chemiluminescence method using a commercial available kit (Adiva Centaur System, Siemens, Germany).

Secondary Outcome Measures

Name	Time	Method
Effects of structured education on blood sugar control.	Baseline and every three months afterwards.	Patients' HbA1c levels were collected at initial recruitment and each visit afterwards. And the above mentioned parameters in group 1(patients with structured education) and group2(patients without structured education) were compared.HbA1c concentration was tested by the Bio-Red Variant automatic measurement system.
Effects of structured education on metabolic control.	Baseline and every three months afterwards.	Patients' triglyceride (TG) and total cholesterol (TC) levels were collected at initial recruitment and each visit afterwards. And the above mentioned parameters in group 1(patients with structured education) and group2(patients without structured education) were compared.
