An interventional study of Life style modification by using and app with a wrist-worn activity tracker and Conventional Life style modification in Obstructive Sleep Apnea and Obesity, sponsored by Seoul National University Hospital. Completed. Open to participants aged 20 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-06-16.

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.
2,162 studies on the registry are indexed under Sleep Apnea Syndromes; 291 are open to participants now.
This study's enrollment of 59 is above the median of 53 across 1,386 interventional studies indexed under Sleep Apnea Syndromes.

Behavioral: Life style modification by using and app with a wrist-worn activity tracker
Control participants, the physicians could assess the lifestyle and recommend further lifestyle modification only on the basis of the participants' recalls
Behavioral: Conventional Life style modification
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.
