Effects of a Supportive Mobile Health for Life Style Modification on Blood Pressure and Insulin Resistance Improvement in People With Metabolic Abnormalities

Not Applicable

Completed

• Conditions: Metabolic Syndrome

• Registration Number: NCT03300271
• Lead Sponsor: Yonsei University

Brief Summary

The purpose of this randomized study is to assess the efficacy of a mobile application for the improvement of blood pressure and insulin resistance in people with metabolic abnormalities.

Detailed Description

The purpose of this randomized study is to assess the efficacy of a mobile application for the improvement of blood pressure and insulin resistance in people with metabolic syndrome.

This study is a 24 week follow up randomized prevention trial. Participants visit for a screening test, then eligible participants are randomly assigned for one of the following arms; 1 intervention group using a mobile application to monitor their life style behaviors, 1 intervention group using a mobile application for personal coaching on purpose of improving their life style behavior, and 1 control group providing education about managing life style behaviors.
