Effect of Type 1 Diabetes on Sleep Fragmentation

Study Overview
=================
Brief Summary
-----------------
The main objective of this study is the objective evaluation of disease related sleep fragmentation in subjects with type 1 diabetes.

Detailed Description
-----------------
The influence of sleep duration and sleep schedules (social jetlag) on glycemic control in type 1 diabetes has been shown in several previous studies, including by the investigators of this study. Following these publications, patients have expressed the opinion via social networks that type 1 diabetes disease is itself a factor that alters the quality of sleep. Indeed, it appears that the cross-sectional studies published to date have focused on the association between the subjects' sleep habits and the balance of their diabetes, without having questioned the role of the pathology on sleep quality. The main objective of this study is the objective evaluation of disease related sleep fragmentation in subjects with type 1 diabetes.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Patients-type 1 diabetes<br>Participants are recruited by e-mail, among the users of the libreview platform (Abbott), who are followed up for type 1 diabetes at the CHU Grenoble Alpes (France), to participate in an anonymous online questionnaire and to allow their glycemic data extracted from the libreview platform to be used for the research. | Other: Cross-sectional observational study<br>* Online questionnaire on the impact of type 1 diabetes on sleep quality<br>* Other names: Online questionnaire;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Objective sleep fragmentation | Number of nocturnal awakenings objectively measured by the number of voluntary glycemia tests performed during the sleep period, according to freestyle recordings. | 1 week | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Subjective sleep fragmentation | Number of self-reported awakenings by patients | 1week | 
| Subjective sleep quality | Analogical scale (from 0 to 10) to grade overall sleep quality | 1 week | 
| Subjective impact of type 1 diabetes on sleep quality. | Analogical scale (from 0 to 10) to grade overall sleep quality | 1 week | 
| Sleep fragmentation by subgroups | Comparison of the number of nocturnal awakenings due to the disease between the following subgroups : Men versus women By age categories (quartiles) According to diabetes control | 1 week |
