Overview
Brief Summary
This trial is to examine the feasibility, acceptability, and preliminary effect of a mHealth social support program on lifestyle modifications among people at risk of metabolic syndrome in Hong Kong at 3- and 6-month follow-ups.
Detailed Description
Metabolic syndrome is a cluster of unhealthy conditions that affects more than 1 billion people in the world. Lifestyle modifications can reduce the risk to develop metabolic syndrome, while the report showed that over 95% of people in Hong Kong did not practice healthy lifestyle. This trial is to examine the feasibility, acceptability, and preliminary effect of a mHealth social support program on lifestyle modifications among people at risk of metabolic syndrome in Hong Kong. Eighty eligible participants will be recruited from community centers and be randomized into intervention group or control group. Participants in the control group will receive a mobile app with limited function, while those in the intervention group will receive a theory-guided mhealth social support program. Data will be collected at baseline, 3 months, and 6 months on the outcomes of feasibility, acceptability, and lifestyle modifications. Data will be analyzed using a generalized estimating equation based on the intention-to-treat principle. The findings of this study will provide valuable information for a full randomized controlled trial.
