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.
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.
