Effectiveness of Digital Health Intervention on Community Health Care in Middle-aged and Older Population in Taiwan

This 6-month cluster randomized trial is conducted in Guishan District, Taoyuan City, Taiwan, to examine the impact of a digital health intervention on community health outcomes among adults aged 50 years and older. From 32 eligible communities, four are randomly selected. Participants must have resided in the community for at least six months, be aged 50 years or older, and provide informed consent. Individuals with severe cognitive impairment, terminal illness, or an inability to use basic digital devices are excluded. Participants in the intervention group will use smart devices to measure blood pressure, fasting glucose, uric acid, total cholesterol, and electrocardiograms. The data are automatically synchronized with a cloud-based health management platform. Physicians will review data monthly and provide individualized consultations and health education sessions at baseline, 3 months, and 6 months. Primary outcomes include anthropometric indices (BMI, body fat percentage, visceral fat rating, skeletal muscle mass index), biochemical markers (fasting glucose, uric acid, cholesterol), and self-reported health and sleep quality. Secondary outcomes include trends in physiological indicators and associations among cardiometabolic risk factors. Ethical approval was obtained from the Institutional Review Board of Chang Gung Memorial Hospital (IRB No.: 202201534B0). Written informed consent is obtained from all participants.
