Personal health app in young-to-midlife adults in Hong Kong

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized intervention compares an algorithm-driven Wellnuts mobile app with self-health assessment and health information to conventional web-based resources in Hong Kong adults aged 25-65. The study aims to promote health-seeking behavior and linkage-to-care for conditions like diabetes risk, cardiovascular risk, and cancers, using a community outreach model with The Lok Sin Tong Benevolent Society. Participants will be assigned to either the Wellnuts app or standard online health information to assess differences in health-awareness and engagement with care. The trial evaluates feasibility, engagement, and potential public health impact of scalable mobile health guidance. The setting includes district health centers in multiple Hong Kong districts to reach diverse, and potentially underserved, populations.
