# The Effect of Health Provider's Feedback on Physical Activity Surveillance Using Wearable Device-Smartphone Application for Resolution of Metabolic Syndrome

**Official Title:** 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

**NCT ID:** [NCT05630456](https://clinicaltrials.gov/study/NCT05630456)

## Key Facts

- **Status:** COMPLETED
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 67
- **Lead Sponsor:** Pusan National University Hospital
- **Conditions:** Metabolic Syndrome, Physical Activity
- **Start Date:** 2020-08-01
- **Completion Date:** 2021-01-31
- **CT.gov Last Update:** 2022-11-29

## Brief Summary

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

## Detailed Description

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.

## Eligibility

- **Minimum age:** 19 Years
- **Maximum age:** 99 Years
- **Sex:** ALL
- **Healthy Volunteers:** Yes

## Arms

- **Intervention Group** (EXPERIMENTAL) — In the intervention group, the researcher gave feedback on the subjects' exercise amount through telephone contact every 2 weeks during the 12-week study period. Through phone consultations, they answered questions about exercise or discussed problems, encouraged to continue exercising, answered questions or discussed problems related to wearable devices and apps, and encouraged continuous data transmission.
- **Control Group** (PLACEBO_COMPARATOR) — In the case of the control group, physical activity is monitored by itself through wearable devices and smartphone apps without phone counseling.

## Interventions

- **Receving feedback** (OTHER) — Receving regular feedback from a health provider
- **No regular feedback** (OTHER) — No regular feedback from a health provider

## Primary Outcomes

- **Fasting blood tests on baseline and 12th week visits** _(time frame: Baseline and 12week)_ — 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)
- **Changes in blood pressure (systolic blood pressure, diastolic blood pressure) at baseline and 12 weeks** _(time frame: Baseline and 12week)_ — Blood pressure was measured in a sitting position after resting using BP-203 RVII(Colin Corp, Aichi, Japan)
- **Changes in waist circumference (cm) at baseline and 12 weeks** _(time frame: Baseline and 12week)_ — 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.
- **Measurement of physical activity through wearable devices** _(time frame: For 12 weeks)_ — 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.

## Secondary Outcomes

- **Changes in body composition at baseline and 12 weeks** _(time frame: Baseline and 12week)_
