- Brief Summary
OSA is a chronic disease with high prevalence that parallels with increasing obesity. Self-management programmes are perceived to be cost-effective in long-term OSA patient care and can supplement regular medical treatments. The current study attempt to examine the effectiveness of 4S on improving apnea severity, cardiovascular health and quality of life in 4S intervention (4S) group, compared to the general hygiene (GH) control group.
- Detailed Description
OSA is a chronic disease with high prevalence that parallels with increasing obesity. OSA affects around 12% and 24% of adults in Hong Kong and China Mainland, respectively. Chronic intermittent hypoxia and sleep fragmentation of OSA leads to cardiometabolic and neurocognitive sequelae (e.g. hypertension, diabetes, daytime sleepiness and depression). Long-term, multidisciplinary management involving patients in decision-making of treatment strategies, shifting from positive airway pressure (PAP) device-focused to the patient-centered chronic care model has been suggested.
Mobile instant messaging (such as WhatsApp/WeChat) are popular and inexpensive for interactive messaging. Smartphone-based self-management interventions were reported improved self-efficacy and clinical outcomes in patients with chronic diseases. The investigator only found one mobile health application to support CPAP therapy for OSA and one ongoing trial of OSA self-management telematic support to improve CPAP adherence. There is underutilization of mobile technology in patient-centered self-management programmes to improve PAP treatment and lifestyle modifications in OSA.
The current study attempt to examine the effectiveness of 4S on improving apnea severity, cardiovascular health and quality of life in 4S intervention (4S) group, compared to the general hygiene (GH) control group. Questionnaire and simple fitness assessment will be used to assess the effectivness of the intervention at 4-month and 12-month follow-up. Focus group interview will be conducted to collect qualiatative feedback on the intervention.

- Primary Outcome Measures
Name Time Method Change in apnea hypopnea index Baseline, 4 months Apnea hypopnea index will be asssessed by sleep test. The apnea hypopnea index is the number of times of apnea or hypopnea during one night, divided by the hours of sleep. The higher the apnea hypopnea index, the more severe sleep apnea is.
- Secondary Outcome Measures
Name Time Method Change in body weight Baseline, 4 months and 12 months Body weight will be measured.
Change in body neck circumference Baseline, 4 months and 12 months Neck circumference will be measured.
Change in apnea hypopnea index Baseline and 12 months Apnea hypopnea index will be assessed by sleep test. The apnea hypopnea index is the number of times of apnea or hypopnea during one night, divided by the hours of sleep. The higher the apnea hypopnea index, the more severe sleep apnea is.
Change in Duration of <90% oxygen desaturation Baseline, 4 months and 12 months Duration of \<90% oxygen desaturation will be assessed by sleep test.
Change objective physical activity level Baseline, 4 months and 12 months Steps count and acceleration pattern of physical activity will be measured by a 7-day waist-worn accelerometer.
Change in lower limb strength Baseline, 4 months and 12 months Lower limb strength will be measured by a 30-second chair stand test.
Change in flexibility Baseline, 4 months and 12 months Flexibility will be measured by a sit and reach test.
Change in balance Baseline, 4 months and 12 months Balance will be measured by a single-leg stance test.
Change in daytime sleepiness Baseline, 4 months and 12 months Daytime sleepiness will be measured by a 8-item Epworth Sleepiness Scale with a 3-point Likert scale. Total scores range from 0 to 24. Higher scores reflect greater daytime sleepiness.
Change in sleep quality Baseline, 4 months and 12 months Sleep quality will be measured by a 7-item Insomnia Severity Index with a 4-point Likert scale. Total scores range from 0 to 28. Higher scores reflect greater severity of insomnia.
Change in dietary habits Baseline, 4 months and 12 months Dietary habits will be measured by 10-item dietary intake and practice questionnaire.
Change in self-efficacy in CPAP use Baseline, 4 months and 12 months Self-efficacy in CPAP use will be measured by a 26-item Self-efficacy Measure for Sleep Apnea. Each Item ranges from 1 to 4: Higher scores indicate greater perceived self-efficacy, greater perceived response efficacy, and higher perceived susceptibility.
Change in body fat Baseline, 4 months and 12 months Body fat will be measured.
Change in functional outcomes of sleep Baseline, 4 months and 12 months Functional outcomes of sleep will be measured by 10-item Functional Outcomes of Sleep Questionnaire with a 4-point Likert scale. Total scores range from 10 to 40. Higher scores reflect better functional outcomes of sleep.
Change in depressive symptoms Baseline, 4 months and 12 months Depressive symptoms will be measured by 9-item Patient Health Questionnaire-9 (PHQ-9) with a 3-point Likert scale. Total scores range from 0 to 27. Higher scores reflect more higher depressive symptoms.
Change in subjective happiness Baseline, 4 months and 12 months Subjective happiness will be measured by 4-item Subjective Happiness Scale with a 7-point Likert scale. Total scores range from 4 to 28. The highest scores reflect greater happiness.

Total scores for both family and peer subscales range from 4 to 28. Higher scores reflect better perceived social support.
Intervention credibility 4 months and 12 months The rationale of the delivered treatment and its efficacy to alleviate sleep apnea will be measured using the 4-item Credibility of Treatment Rating Scale. Each item ranges from 1-6. The higher scores indicate higher credibility.
