Evaluating a Mobile App to Improve Health Awareness and Care Linkage Among Adults Aged 25-65 in Hong Kong

What This Trial Is About

Researchers are evaluating the effectiveness of Wellnuts, a mobile application designed for self-health assessment, in supporting asymptomatic young-to-midlife adults in Hong Kong. The study aims to promote health awareness, encourage health-seeking behavior, and improve linkage to care compared with conventional web-based health resources. This project focuses on prevention and addressing common health conditions and modifiable behavioral risks in a bilingual, technologically competent population. Participants are randomly assigned to one of two groups the intervention group uses the Wellnuts app, which provides evidence-based, algorithm-driven self-assessments and tailored health recommendations the control group accesses standard health information from the Centre for Health Protections website. The app identifies participants at risk and suggests appropriate tests and follow-up actions. The study is conducted with collaboration from The Lok Sin Tong Benevolent Society to reach a broad audience at a relatively low cost. During the study, participants will be monitored for their engagement with health services, lifestyle behaviors, and satisfaction with the project at 3 and 6 months. Researchers will track how many seek medical assistance, adopt healthy behaviors, and attend recommended follow-up tests. Outcome measures include the proportion of participants who seek medical help and lifestyle improvements. The study runs from June 2024 to March 2027, involving randomization and ongoing data collection to understand the apps impact on health promotion and behavior modification.
