The Effect of Feedback on Physical Activity Surveillance Using Wearable Device-Smartphone Application for Resolution of Metabolic Syndrome in Aged 60 or Older

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.

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.
