Personalized, context-aware messages effectively increased physical activity (PA) in sedentary employees during work hours. This intervention successfully broke prolonged sitting, demonstrating a significant boost in workplace activity compared to static reminders.
Area of Science:
- Occupational Health
- Behavioral Science
- Digital Health
Background:
- Sedentary occupations contribute to physical inactivity, increasing risks for chronic diseases like obesity and diabetes.
- Rising health concerns necessitate strategies to enhance employee activity during work and daily life.
Purpose of the Study:
- To evaluate the effectiveness of personalized, context-aware messages in boosting employee physical activity.
- To test the hypothesis that tailored messages, considering user data and environment, outperform static reminders in increasing daily active time.
Main Methods:
- A 66-day mixed-methods study in Qatar involving 58 sedentary employees.
- Participants used either a static reminder app (MotiFit Lite) or a personalized, context-aware message app (MotiFit).
- Data collected included message engagement, step counts, and user responses to assess intervention impact.
Main Results:
- The personalized message group (MotiFit) showed significantly higher engagement than the control group (P<.001).
- Context-aware motivational messages significantly increased physical activity (PA) at work compared to static messages (P<.001).
- No significant impact on overall daily activity levels was observed based on message type (P=.06).
Conclusions:
- Personalized, context-aware messages effectively motivate employees to increase physical activity in the workplace.
- Further research is needed to explore the impact of these messages on overall daily activity levels.
