Smartphone Application Intervention on Obstructive Sleep Apnea Among Overweight and Obese High‐Tech Employees: A Randomized Controlled Trial

The aim of this study was to examine the effectiveness of an adjusting lifestyle intervention with a smartphone application (app) in managing obstructive sleep apnea (OSA) among overweight and obese high-tech employees. A 6-months three-armed randomized controlled trial was employed. A total of 144 eligible participants were randomly allocated into the smartphone app 'MyFitnessPal' plus education (MFPE; n = 48), 'MyFitnessPal'-only (MFP-only; n = 50) and the control group (n = 46) at a 1:1:1 ratio. The data were collected using related questionnaires and portable sleep monitor. Generalized estimating equation was used to analyze data. Results revealed that there was a significant interaction between time and group in BMI (Wald χ2 = 4.47, p = 0.04) in the MFPE after the 12th week of the intervention. Nevertheless, there was no significant interaction between group and time observed in apnea-hypopnea index (AHI) score after 24 weeks of intervention. The adjustment lifestyle integrated with an app may offer a simple and cost-effective approach. The findings of this study may provide precious information for occupational healthcare providers, facilitating health promotion in the workplace for overweight employees with OSA.
