Effect of a Mobile-Based Hydration Tracking Program on Knowledge, Attitudes, and Behaviors in Older Adults

"Intervention Description:~The SIVI Hydration Application is a mobile-compatible, web-based behavioral intervention designed specifically for older adults. It supports self-monitoring and self-management of daily fluid intake through features such as personalized fluid goals, visual drink-logging with icons, daily reminders, progress graphics, educational videos, and motivational digital badges. The app was developed using gerotechnology and universal design principles to accommodate cognitive and sensory changes common in aging. Its unique focus on hydration behavior, combined with usability features like large fonts, high contrast, and voice-assisted guidance, distinguishes it from general health or diet tracking apps. Participants use the app for 8 weeks as part of a structured intervention with training and weekly follow-up."
