Obesity, Obstructive Sleep Apnea
Conditions
Brief summary
This study aimed to investigate the effects of a mobile phone app linked to hospital electronic medical record (EMR) system on weight reduction and obstructive sleep apnea (OSA). Adults aged \> 20 years with witnessed snoring or sleep apnea from a sleep clinic of a tertiary center were prospectively enrolled, and the participats were randomized into app user and control groups. The mobile app was designed to collect daily lifestyle data by wearing a wrist activity tracker and reporting dietary intake. At the visit after 2 weeks of use, a summary of the lifestyle was displayed on the hospital EMR and reviewed by both physicians and app users. Further lifestyle modification was encouraged on the basis of the electronically collected data. In the control group, the lifestyle modification performed as the usual practice. All participants underwent Watch PAT and body mass index (BMI) measurement twice: on enrollment; and after 4-weeks follow up. Changes of BMI, and parameters of sleep related breathing were analyzed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| changes in body weight | base line and after 4weeks of life style modiciation | body weight measurement and calculate into body mass index (BMI) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| apnea hypopnea index (AHI) | base line and after 4weeks of life style modiciation | number of apnea and or hypopnea event per hour during sleep |
| respiratory distress index (RDI) | base line and after 4weeks of life style modiciation | AHI + number of respiratory effor related arousal (RERA) per hour during sleep |
| oxygen desaturation index (ODI) | base line and after 4weeks of life style modiciation | number of desaturation event (peripheral oxygen satuation less than 90%) per hour during sleep |
| sleep time proportion with snoring loudness > 45dB | base line and after 4weeks of life style modiciation | total duration of the snoring loudness \>45 dB devided by the total sleep time (%) |
| lowest oxygen saturation | base line and after 4weeks of life style modiciation | the degree of the lowest oxygen saturation measured during sleep |
