Brief Summary: The Effect of Feedback on Physical Activity Surveillance using Wearable Device-Smartphone Application for Resolution of Metabolic Syndrome in Aged 60 or older; a 12-Week Randomized Control Study

Detailed Description: Research on whether wearable device interventions can effectively prevent metabolic syndrome remains insufficient. This study aimed to evaluate the effect of feedback on clinical indicators in patients with metabolic syndrome aged 60 or older on activities measured using wearable devices, such as smartphone apps. Patients aged 60 or older diagnosed with metabolic syndrome were recruited and prescribed to survive for 12 weeks using wrist-worn devices (B.BAND, B Life Inc, Korea). The block randomization method was used to distribute the participants between an intervention group (n=20) and control group (n=20). In the intervention group, an experienced study coordinator provided feedback on physical activity to individuals through telephone counseling every other week.

Recruitment & Eligibility

Inclusion Criteria

Diagnosed with metabolic syndrome by a doctor.
Aged 60 or older.
A person who understands the clinical trial process and signs the consent form
Possession of a smartphone and a daily mobile phone user for the past 3. months and expected to use for more than 3 months.
A person who agrees to provide the data on the amount of physical activity measured and collected by a wearable device.
A person who can exercise at an intensity more than walking for 12 weeks.

Exclusion Criteria

Under the aged 60.
A person who does not agree to provide data on physical activity.
Those who who are judged to have difficulty in exercising such as walking due to uncontrolled diabetes, high blood pressure or serious cardiovascular disease.
A person who is not used to or is reluctant to use a smartphone app.
Those who have difficulty wearing wearable devices due to skin diseases around their wrists.
A person who is expected to have an unintended change in weight over the next three months due to current pregnancy and planning, thyroid disease, cancer, etc.

Arm && Interventions

Group	Intervention	Description
Intervention Group	Receving feedback	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 encouraged continuous data transmission.
Control Group	No regular feedback	In the case of the control group, physical activity is monitored by itself through wearable devices and smartphone apps without phone counseling.

Primary Outcome Measures

Name	Time	Method
Measurement of physical activity through wearable devices	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. Researchers who have been granted access can check and track participants' physical activity on a daily basis through a web page.
Changes in waist circumference (cm) at baseline and 12th week visits	Baseline and 12th week	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.
Changes in blood pressure (systolic blood pressure, diastolic blood pressure) at baseline and 12th week visits	Baseline and 12th week	Blood pressure was measured in a sitting position after resting using BP-203 RVII(Colin Corp, Aichi, Japan).
Changes in fasting blood tests at baseline and 12th week visits	Baseline and 12th week	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.

Secondary Outcome Measures

Name	Time	Method
Pulse wave velocity measurement on baseline and 12th week visits	Baseline and 12th week	Pulse wave velocity was measured in a comfortable supine position using the VP-1000 plus (Omron Healthcare, Bannockburn, IL).
Depression index at baseline and 12th week visits	Baseline and 12th week	All participants completed the Beck Depression Inventory (BDI) questionnaires.
Changes in height at baseline and 12th week visits	Baseline and 12th week	Height in meters were measured using a digital scale and stadiometer (BSM370, Biospace Co Ltd, Seoul).
Changes in body composition at baseline and 12th week visits	Baseline and 12th week	Body composition was measured by bioelectrical impedance analysis (Inbody 720, Biospace Co Ltd, Seoul)
Stress scale questionnaires at baseline and 12th week visits	Baseline and 12th week	All participants completed the Perceived Stress Scale (PSS) questionnaires.
Changes in body weight at baseline and 12th week visits	Baseline and 12th week	Body weight in kilograms were measured using a digital scale and stadiometer (BSM370, Biospace Co Ltd, Seoul).
