Brief 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.

Inclusion criteria
* University students with a body mass index of 24 kg/m2 or above at one university campus. * No physical limitations that would prevent them from performing physical activity. * Not currently pregnant women. * Having a smart phone that would allow them to connect to a Mi Band.
Exclusion criteria
* The university student who expects to be absent for more than 2 weeks or expects a suspension or transferring to another school during the implementation of the intervention.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Waist to hip ratio (WHR) | Change from baseline waist to hip ratio at 6 weeks and 12 weeks | Waist to hip ratio was measured by ioi 353 body composition analyzer (Jawon Medical) |
| Weight | Change from baseline weight at 6 weeks and 12 weeks | Weight was measured by ioi 353 body composition analyzer (Jawon Medical) |
| Waist circumference (WC) | Change from baseline waist circumference at 6 weeks and 12 weeks | Waist circumference (nearest 0.1 cm) was measured in duplicate with a non-expandable tape at the midpoint between the lowest rib and the iliac crest. A third measurement was taken if the first two differed by 1 cm. |
| Soft lean mass (SLM) | Change from baseline soft lean mass at 6 weeks and 12 weeks | Soft lean mass was measured by ioi 353 body composition analyzer (Jawon Medical) |
| Mass of body fat (MBF) | Change from baseline mass of body fat at 6 weeks and 12 weeks | Mass of body fat was measured by ioi 353 body composition analyzer (Jawon Medical) |
| Percent body fat (PBF) | Change from baseline percent body fat at 6 weeks and 12 weeks | Percent body fat was measured by ioi 353 body composition analyzer (Jawon Medical) |
| Body mass index (BMI) | Change from baseline body mass index at 6 weeks and 12 weeks | Body mass index was computed as average weight (kg)/average height (m2) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Physical activity | Change from baseline physical activity at 6 weeks and 12 weeks | Physical activity was assessed by International Physical Activity Questionnaire (Taiwan) short-form (IPAQ-SF) |
| Sedentary behavior | Change from baseline sedentary behavior at 6 weeks and 12 weeks | Sedentary behavior was assessed by Rosenberg's Sedentary Behavior Questionnaire (SBQ) |
| Daily steps | Change from baseline daily steps at 6 weeks and 12 weeks | Daily steps was assessed by Mi Band (Xiaomi Inc.) |
Other
| Measure | Time frame |
|---|---|
| Self-efficacy for physical activity questionnaire | Change from baseline self-efficacy for physical activity at 6 weeks and 12 weeks |
| Self-efficacy for reducing sedentary behavior questionnaire | Change from baseline self-efficacy for reducing sedentary behavior at 6 weeks and 12 weeks |
| Self-regulation questionnaire | Change from baseline self-regulation at 6 weeks and 12 weeks |
