Connected Health Care in Exercise Program for Obesity

January 22, 2019 updated by: Regis Fernandes, Mayo Clinic

Feasibility and Explorative Study to Test the Superiority of Connected Health Care Using Wearable Device to Improve Body Composition and Fitness Level

Many kinds of wearable technology have become available, but the superiority of those devices in weight loss compared to the standard care without them is uncertain. The possible problems are long-term self-motivation, utility and validity of the device, and outcome measures in clinical trials. The connected health care with motivational interviewing as an intervention, and body composition parameters in addition to body weight as outcome measures are employed in the project. The expected outcome is that connected health care, which is more individualized approach by heath care professionals, is more effective compared to self-monitoring using wearable devices. Two types of wearable device are going to be used to monitor 1) body activity and 2) heart rate variables during exercise which reflect fitness level in this study in order to investigate appropriate monitoring parameters to predict outcome measures.

The hypothesis is that addition of connected health system will result in improvement of body composition and fitness level compared to self-monitoring.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients with age 18 to 59 years old and body mass index between 30 to 39.9 are to be enrolled at Mayo Clinic in Arizona. All enrolled subjects receive wearable monitoring devices with remote tracking capability and brochure regarding nutrition and physical exercise with basic instruction. Subjects are randomly assigned to connected health care group versus self-monitoring group. Connected health care group will have 2 interviews about physical exercise and 6 communications with individualized instruction and counseling of their exercise including the usage of the monitoring devices. Self-monitoring group will do physical exercise following the initial basic instruction and self-monitor them.

All subjects visit Mayo Clinic to get outcome measures at 0, 12, and 24weeks. Outcome measures will be compared before, at 12 weeks, and after the 24 weeks of the fitness program.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Connected Health
This group will get 2 interviews about physical exercise (exercise instruction with motivational interview) and 6 communications with individualized instruction and counseling of their physical exercise (investigators can access activity data and exercise log) including the usage of the monitoring device.
Behavioral: Exercise instruction with motivational interview
An activity tracker and a heart rate monitor to track the participants activity and exercise records will be used. In addition to the basic instruction of exercise and nutrition, an exercise physiologist provides individualized exercise instruction with a motivational interviewing skill, which is a different style from traditional persuasive style of communication between the healthcare professionals and patients.
Active Comparator: Self-Monitoring
This group will do physical exercise following the initial instruction and self-monitor them. Investigators can access activity data and exercise log but will not discuss with the subjects about the data.
Behavioral: Self-monitoring
An activity tracker and a heart rate monitor to track the participants activity and exercise records will be used. Basic instruction about exercise and nutrition is provided at the initial visit.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Waist circumference
Time Frame: Baseline and 24 weeks
Waist circumference is measured by tape at the end expiration while the patient is standing. Units centimeters.
Baseline and 24 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in weight
Time Frame: Baseline and 24 weeks
Weight is measured using a commercially available body weight scale (TANITA body composition monitors). Units kg.
Baseline and 24 weeks
Change in body fat percentage
Time Frame: Baseline and 24 weeks
Body fat percentage is measured using a commercially available body fat scale (TANITA body composition monitors). Units percentage.
Baseline and 24 weeks
Change in physical activity score
Time Frame: Baseline and 24 weeks

International Physical Activity Questionnaire is filled out by patients. The International Physical Activity Questionnaire Long Form (IPAQ) (www.ipaq.ki.se) is to assess levels and patterns of physical activity.

Continuous score expressed as "MET (metabolic equivalent)-min/week: MET level*minutes of activity/day*days per week" is calculated. Higher number means higher level of physical activity that a subject performed during last 7 days. The estimated range is from 0 to 3000. Units MET-minutes.
Baseline and 24 weeks
Change in Physical Activity Vital Sign
Time Frame: Baseline and 24 weeks

Physical Activity Vital Sign (PAVS) (Greenwood JL, 2010) is a short physical activity assessment using closed ended questions to ask how many days a subject performed physical activity during the past week. Higher number means a subject spent more days on performing physical activity.

The range is from 0 to 7. Units days.
Baseline and 24 weeks
Change in Veterans Specific Activity Questionnaire
Time Frame: Baseline and 24 weeks
Veterans Specific Activity Questionnaire (VASQ) (Myers J, 2001) is a brief self administered questionnaire to predict exercise capacity (METs, metabolic equivalents). A subject select the minimum activity level that cause fatigue, short of breath, or discomfort. Higher number means higher fitness level of a subject. the range is from 1 to 13. Units METs.
Baseline and 24 weeks
