CALLSAS Study: Effect of Continuous Positive Airway Pressure Treatment for Obstructive Apnea on Phone Usage Habits

Study Overview
=================
Brief Summary
-----------------
Continuous positive airway pressure (CPAP) treatment improves sleepiness, depression and social activities in patients with obstructive sleep apnea (OSA). This evolution can be captured from changes in phone usage habits coupled with a mobile-based services. The aim of this study is to assess the impact of CPAP treatment on phone usage habits in OSA patients.

Detailed Description
-----------------
Callsas is a prospective study embarking newly diagnosed obstructive sleep apnea patients initiated to CPAP treatment. The primary objective is to analyze the modifications in phone usage habits before and after CPAP treatment. Secondary objectives: Correlation between changes in phone usage habits and evolution of sleepiness Correlation between changes in phone usage habits and evolution of depression scale Correlation between changes in phone usage habits and evolution of quality of life Correlation between changes in physical activity measured by phones and evolution of physical activity objectively measured by actigraphy and gait platform Correlation between phone usage habits and CPAP adherence

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effect of CPAP on phone usage habits indices | Changes in indices of phone usage habits | from 6 months before CPAP treatment until 6 months after CPAP treatment initiation | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time course evolution of phone usage habits indices and evolution of sleepiness | Assessment of sleepiness by ESS | from CPAP initiation until 6 months after CPAP treatment initiation | 
| Time course evolution of phone usage habits indices and evolution of depression | Assessment of depression by Pichot scale | from CPAP initiation until 6 months after CPAP treatment initiation | 
| Time course evolution of phone usage habits indices and evolution of quality of life | Assessment of quality of life by SF-36 | from CPAP initiation until 6 months after CPAP treatment initiation | 
| Time course evolution of phone usage habits indices and evolution of locomotion | patterns of locomotion objectively measured by a gait platform | from CPAP initiation until 6 months after CPAP treatment initiation | 
| CPAP adherence | Time course evolution of CPAP adherence assessed by telemonitoring versus time course evolution of phone usage habits | from CPAP initiation until 6 months after CPAP treatment initiation | 
| Access to care as a predictor of CPAP adherence | Care access questionnaire developed by ODENORE and National French insurance | from CPAP initiation until 6 months after CPAP treatment initiation | 
| Effect of food habit with CPAP treatment | Changes in food frequence questionnaire | At CPAP initiation and at 6 months after CPAP treatment initiation |
