Clinical Trial Summary

This is an eight-month research project using one group pretest-midst-posttest design. This study is based on self-efficacy and self-regulation of Social Cognitive Theory. The investigators will recruit 50 university students with a body mass index of 24 kg/m2 or above at one university campus. Participation is completely voluntary. After pretesting, a 12-week "Mi Band Step Challenge" will be launched immediately. Participants will be assessed with the validated instruments of International Physical Activity Questionnaire (IPAQ)-Taiwan short-form, Sedentary Behavior Questionnaire (SBQ), self-efficacy and self-regulation questionnaires. Mi Band activity trackers will be used to monitor step counts. An ioi 353 body composition analyzer will be used to assess body composition. Data will be analyzed using generalized estimating equation (GEE).

The expected outcomes of this study include: (1) "Mi Band Step Challenge" will be developed based on the theory, which is expected to be effective. If this is true, the intervention can be packaged and applied at different types of colleges and universities with overweight students. (2) "Mi Band Step Challenge" has the potential to be used for the reference of the healthy weight - physical activity, which is embedded in the School Health Promotion Program executed by the Ministry of Education. (3) The result of this study can serve as an example for the promotion of evidence-based health care.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Self-regulation questionnaire		Change from baseline self-regulation at 6 weeks and 12 weeks
Other	Self-efficacy for physical activity questionnaire		Change from baseline self-efficacy for physical activity at 6 weeks and 12 weeks
Other	Self-efficacy for reducing sedentary behavior questionnaire		Change from baseline self-efficacy for reducing sedentary behavior at 6 weeks and 12 weeks

Primary	Waist to hip ratio (WHR)	Waist to hip ratio was measured by ioi 353 body composition analyzer (Jawon Medical)	Change from baseline waist to hip ratio at 6 weeks and 12 weeks
Secondary	Physical activity	Physical activity was assessed by International Physical Activity Questionnaire (Taiwan) short-form (IPAQ-SF)	Change from baseline physical activity at 6 weeks and 12 weeks
Secondary	Sedentary behavior	Sedentary behavior was assessed by Rosenberg's Sedentary Behavior Questionnaire (SBQ)	Change from baseline sedentary behavior at 6 weeks and 12 weeks
Secondary	Daily steps	Daily steps was assessed by Mi Band (Xiaomi Inc.)	Change from baseline daily steps at 6 weeks and 12 weeks
