Brief Summary:
For last decade, the innovation of mobile health platform has brought new opportunities for disease management. Previous studies have shown that health management programs based on mobile platforms for patients with diabetes can improve patients' glucose control, self-management ability and quality of life. Type 1 diabetes mellitus (T1DM) due to its characteristics needs long-term linkage care throughout the lifespan cycle of patients. Therefore, this study intends to construct a prospective and open T1DM cohort based on mobile application and platform, to deliver home-community-hospital joint management for patients, and to provide follow-up online or offline every 3 months lasting for 10 years. Mainly, the objective of this study is to observe the blood glucose control outcome of T1DM patients. Secondly, the control of comprehensive metabolic indicators such as blood pressure and blood lipid, occurrence and progression of acute and chronic complications, and psychosocial status were included as well, expecting to provide scientific evidence for continuously improving the quality of T1DM management.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. HbA1c [ Time Frame: Outcome evaluation at 10 years. ]
    HbA1c is one of the indicators that reflects the level of blood glucose control overall. Blood sample will be required and tested.

  2. Time in range (TIR) [ Time Frame: Outcome evaluation at 10 years. ]
    TIR is one of the indicators that reflects the level of blood glucose control from the point of view of target time. Continuous glucose monitoring (CGM) devices will be used.

  3. Incidence of hypoglycemia [ Time Frame: Outcome evaluation at 10 years. ]
    Incidence of hypoglycemia is one of the indicators that reflects the level of blood glucose control. Hypoglycemia is defined as blood glucose lower than 3.9mmol/L with or without symptoms. Incidence of hypoglycemia is occurence times per month according to patients self-reported.


Secondary Outcome Measures :
  1. Comprehensive metabolic control [ Time Frame: Outcome evaluation at 10 years. ]
    Blood pressure is one of the control level comprehensive metabolic indicators, including systolic blood pressure (SBP) and diastolic blood pressure (DBP).

  2. Comprehensive metabolic control [ Time Frame: Outcome evaluation at 10 years. ]
    Blood lipid is one of the control level of comprehensive metabolic indicators, including total cholesterol (TC), total triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C).

  3. Occurrence of Diabetes-related complications. [ Time Frame: Outcome evaluation at 10 years. ]
    To observe and analyze occurrence of diabetes-related acute and chronic complications. Acute complications of diabetes include diabetic ketoacidosis (DKA), hypoglycemia and Hyperglycemic Hyperosmolar Syndrome (HHS). Chronic complications of diabetes including retinopathy, neuropathy nephropathy and lower extremity amputations (LEA). Other diabetes-related complications include cardiovascular disease, heart failure, stroke and death.

  4. Progression of Diabetes-related complications. [ Time Frame: Outcome evaluation at 10 years. ]
    To observe and analyze progression of diabetes-related acute and chronic complications. Acute complications of diabetes include diabetic ketoacidosis (DKA), hypoglycemia and Hyperglycemic Hyperosmolar Syndrome (HHS). Chronic complications of diabetes including retinopathy, neuropathy nephropathy and lower extremity amputations (LEA). Other diabetes-related complications include cardiovascular disease, heart failure, stroke and death.

  5. Anxiety condition. [ Time Frame: Outcome evaluation at 10 years. ]
    Anxiety condition is one of the psychosocial status indicators, and Self-Rating Anxiety Scale (SAS) will be used to assess anxiety level. The score ranges from 20 to 100, and higher score indicates more prone to anxiety.

  6. Anxiety condition. [ Time Frame: Outcome evaluation at 10 years. ]
    Anxiety condition is one of the psychosocial status indicators. Generalized Anxiety Disorder 7-Item Scale (GAD-7 scale) will be used to assess anxiety symptoms. The score ranges from 0 to 7, and higher score indicates more anxiety symptoms.

  7. Depression condition. [ Time Frame: Outcome evaluation at 10 years. ]
    Depression condition is one of the psychosocial status indicators, and Self-Rating Depression Scale (SDS) will be used to assess depression level. The level of depression is measured by depression severity index. The index ranges from 0.25 to 1.0, with higher scores associated with greater depression.

  8. Depression condition. [ Time Frame: Outcome evaluation at 10 years. ]
    Depression condition is one of the psychosocial status indicators, and Patient Health Questionnaire-9 (PHQ-9) will be used to assess depression level. The score ranges from 0 to 27. A higher score indicates a higher degree of depression.

  9. Depression condition. [ Time Frame: Outcome evaluation at 10 years. ]
    Depression condition is one of the psychosocial status indicators, and Problem Areas in Diabetes-Short form (PAID-5) will be used to evaluate the diabetes related emotional distress, which is strongly association with depression. A score ≥40 indicates high diabetes-related distress.

  10. Life quality. [ Time Frame: Outcome evaluation at 10 years. ]
    Life quality is one of the psychosocial status indicators, and specific scales as World Health Organization-5 well-being index (WHO-5) will be used to assess this factor. A score <50 indicates poor psychological well-being.
