The Effect of Health Provider's Feedback on Physical Activity Surveillance using Wearable Device-Smartphone Application for Resolution of Metabolic Syndrome; a 12-Week Randomized Control Study
Patients diagnosed with metabolic syndrome were recruited and prescribed to live for 12 weeks using a wrist-wearable device (B.BAND, B Life Inc, Korea). The block randomization method was used to distribute the participants between an intervention group (n=35) and control group (n=32). In the intervention group, an experienced study coordinator provided feedback on physical activity to individuals through telephone counseling every other week.

Fasting blood tests on baseline and 12th week visits
Blood samples were collected from the Jeonju vein after fasting for 6 hours and analyzed in our hospital's laboratory. The lipid profile was tested using an automated analyzer (Hitachi 747, Hitachi Corp, Japan) and enzyme colorimetric method. FPG levels were evaluated using glucose oxidase methods and Synchron LX 20 (Beckman Coulter, Fullerton, CA)
Time frame: Baseline and 12week
Changes in blood pressure (systolic blood pressure, diastolic blood pressure) at baseline and 12 weeks
Blood pressure was measured in a sitting position after resting using BP-203 RVII(Colin Corp, Aichi, Japan)
Time frame: Baseline and 12week
Changes in waist circumference (cm) at baseline and 12 weeks
The waist circumference was evaluated by a trained examiner (after normal exhalation) to the nearest millimeter from the midpoint between the lower edge of the rib and the iliac ridge.
Time frame: Baseline and 12week
Measurement of physical activity through wearable devices
Investigators provided with wrist-wearable device (B.BAND, B Life Inc, Korea), which allowed them to wear and live for 12 weeks. Subsequently, a compatible app was installed on the participants' mobile phones and connected to a wearable device. Researchers who have been granted access can check and track participants' steps, calorie consumption, and MVPA (moderate- to vigorousintensity physical activity) on a daily basis through a web page.
Time frame: For 12 weeks
Changes in body composition at baseline and 12 weeks
Body weight in kilograms and height in meters were measured using a digital scale and stadiometer (BSM370, Biospace Co Ltd, Seoul), while the study subjects were dressed in light clothing without shoes. Body composition was measured by bioelectrical impedance analysis (Inbody 720, Biospace Co Ltd, Seoul)
