Brief summary
The purpose of this study is to test an intervention which uses a personalized mobile-technology based approach that aims to promote physical activity and reduce sedentary behaviour in inactive working Singaporean adults.
Detailed description
Considering the increasing burden in type 2 diabetes mellitus and other chronic diseases, the promotion of physical activity and reduction of sedentary behavior have an important role to improve population health. Primarily, potential participants will be identified and recruited among participants from the Singapore Health Study (SHS) 2014 based on pre-specified selection criteria . SHS is a cross-sectional study of adults between 18 and 79 years which is conducted annually to monitor health, health behavior and health determinants among the Singapore general population. All eligible participants will be randomized with a 1:1 ratio to intervention and control group. Intervention group participants will receive a personalized mobile-technology based intervention to promote physical activity. It consists of four components: 1. General physical activity educational materials 2. Wearable activity tracking devices to enable the intervention participants to self-monitor their physical activity behavior and receive real-time feedback 3. Access to an online map of Singapore providing location based information about leisure time physical activity opportunities 4. Personalized text messages which include, educational information, tailored theory-based motivational messages, as well as compliance enhancing reminders Control group participants will receive general physical activity educational materials, identical in content to that of the general educational materials of intervention group participants. All participants will be assessed at baseline, 6 months and 12 months after the intervention by accelerometry and self-reported questionnaires.
