Mi Band Step Challenge to Improve Body Composition in Overweight University Students

Study Overview
=================
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Weight | Weight was measured by ioi 353 body composition analyzer (Jawon Medical) | Change from baseline weight at 6 weeks and 12 weeks | 
| Waist circumference (WC) | 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. | Change from baseline waist circumference at 6 weeks and 12 weeks | 
| Soft lean mass (SLM) | Soft lean mass was measured by ioi 353 body composition analyzer (Jawon Medical) | Change from baseline soft lean mass at 6 weeks and 12 weeks | 
| Mass of body fat (MBF) | Mass of body fat was measured by ioi 353 body composition analyzer (Jawon Medical) | Change from baseline mass of body fat at 6 weeks and 12 weeks | 
| Percent body fat (PBF) | Percent body fat was measured by ioi 353 body composition analyzer (Jawon Medical) | Change from baseline percent body fat at 6 weeks and 12 weeks | 
| Body mass index (BMI) | Body mass index was computed as average weight (kg)/average height (m2) | Change from baseline body mass index at 6 weeks and 12 weeks | 
| 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 Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 | 
| Sedentary behavior | Sedentary behavior was assessed by Rosenberg's Sedentary Behavior Questionnaire (SBQ) | Change from baseline sedentary behavior at 6 weeks and 12 weeks | 
| Daily steps | Daily steps was assessed by Mi Band (Xiaomi Inc.) | Change from baseline daily steps at 6 weeks and 12 weeks |
