Type 1 Diabetes Mellitus
Conditions
Brief summary
A registry of individuals with type 1 diabetes open to all patients with type 1 diabetes living in Canada will be established. The objective of this registry will be to measure the frequency and the severity of episodes of hypoglycemia. Participants will be invited to answer questionnaires about the frequency of their hypoglycemic episodes, their fear about hypoglycemia, their symptoms of hypoglycemia, the factors in cause (insulin therapy, nutrition, exercise, etc.), etc. Participation to the registry is divided in 3 phases. The first phase is mandatory for all participants. Phases 2 and 3 are optional.
Detailed description
The objective of phase 1 is to draw an overall picture of the population with type 1 diabetes in Canada in terms of demographics, diabetes treatment, hypoglycemia frequency and diabetes complications. It takes about 10 minutes to answer the questionnaire. If the participant uses a continuous glucose monitor and agrees, the participant is invited to send the latest report of the continuous glucose monitor. The objective of phase 2 is to characterize the causes, experience and consequences of hypoglycemia. Phase 2 also involves, if the participant accepts and live in the province of Quebec or Alberta, to provide the research team with their latest blood and urine tests as well as their list of medications. The objective of phase 3 is to collect information on diabetes and hypoglycemia treatment, hyperglycemia management, sleep habits, depression, physical activity and the benefits of technologies to reduce the frequency of hypoglycemia. Phase 3 also involves, if the participant agrees, answering a food questionnaire, wearing a step counter, measuring waist circumference

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of non-severe hypoglycemic episodes | 12 months | Participants will be asked to report the number of non-severe hypoglycemic episodes in the last 12 months in a questionnaire designed by the investigators. The definition of non-severe hypoglycemia is a blood sugar below 3.0 mmol/L that the participant was able to treat himself |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Fear of hypoglycemia | 6 months | Fear of hypoglycemia will be assessed by the Hypoglycemia Fear Survey II. |
| Diabetes distress | 1 month | Diabetes distress will be assessed by the Diabetes Distress Scale. |
| Medical follow-up for diabetes | 12 months | Participants will be asked to report in a questionnaire designed by the investigators how many times in the last 12 months they have seen a health care professionals (family doctor, medical specialist, nurse, nutritionnist, kinesiologist, psychologist, pharmacist, social worker). |
| Insulin doses | 3 days | Participants will be asked to report in a questionnaire designed by the investigators their insulin doses of the last 3 days (basal insulin and insulin given at mealtime). |
| Number of severe hypoglycemic episodes | 12 months | Participants will be asked to report the number of severe hypoglycemic episodes in the last 12 months in a questionnaire designed by the investigators. The definition of severe hypoglycemia is low blood sugar levels requiring help from another person or use of glucagon or hospitalization or loss of consciousness. |
| Sleep habits | 1 month | Sleep habits will be assessed by the Pittsburgh Sleep Quality Index |
| Depression | 2 weeks | Depression will be assessed by the Patient Health Questionnaire (PHQ-9) |
| Number of steps | 14 days | The number of steps will be measured by a pedometer |
| Physical activity | 1 week | Physical activity will be assessed by the International Physical Activity Questionnaire. |
