Outcomes

Primary Outcomes

The measured value of Zc score of "sleepiness on rising" in the OSA sleep inventory MA version (OSA-MA) after the 12-week intervention

The OSA-MA is used to assess sleep quality. Individuals are asked to complete the questionnaire immediately after waking on the examination day and two days before the examination. The raw scores from each examination day will be converted to Zc scores, and the three-day mean, rounded to one decimal place, will be used as the measured value. "Sleepiness on rising" consists of four questions. Higher score indicates better outcome.

Time frame: After the 12-week intervention

Secondary Outcomes

The measured value of Zc score of "sleepiness on rising" in the OSA-MA after the 6-week intervention

Time frame: After the 6-week intervention

The measured values of Zc score of "initiation and maintenance of sleep," "frequent dreaming," "refreshing," and "sleep length" in the OSA-MA after the 6 and12-week intervention

The OSA-MA is used to assess sleep quality. Individuals are asked to complete the questionnaire immediately after waking on the examination day and two days before the examination. The raw scores from each examination day will be converted to Zc scores, and the three-day mean, rounded to one decimal place, will be used as the measured value. "Initiation and maintenance of sleep" consists of five questions, "frequent dreaming" consists of two questions, "refreshing" consists of three questions, and "sleep length" consists of two questions. Higher scores indicate better outcomes.

Time frame: After the 6 and12-week intervention
