Evaluation of a Commercial Gaming Impact in a Childhood Obesity Intervention

The Center for Health Reform and Modernization at UHG will compare levels of physical activity, assessed by accelerometry, among children randomly assigned to WMA or WM+E groups. Specific aims of this evaluation are:

• Compare the two groups on changes in the daily minutes of physical activity (mild, moderate and vigorous) after sessions 1, 8 and 15, respectively (Sessions are typically one week a part. Due to holiday schedules, there may be a lapse of two weeks between sessions).
• Compare the two groups on changes in the daily minutes of sedentary behavior after sessions 1, 8 and 15, respectively
• Compare the two groups on changes in relative weight (weight, BMI percentile, BMI z-score) at sessions 1, 8, and 16 weeks, respectively
• Compare the two groups on measures of program satisfaction at 1, 8, and 16 weeks, respectively

Participation in the post session one session is required in order to be eligible for the study requirements include:

• A signed consent/ assent from the parent and child.
• The child must be able to participate in physical activity similar to exercise gaming
• The family must have a TV/monitor that supports Microsoft Kinect
• The family must have internet connection in the home

The family's decision to participate in the study does not affect the child's'/ parent's overall ability to fully participate in the JOIN Program. All JOIN program materials will be the same whether or not JOIN participants agree to be in the study. All aspects of the study will be conducted outside of the standard class time. Interested and eligible participants will be scheduled to attend a study visit immediately after their first JOIN class. During that study visit, written informed consent/assent from the parent/child will be obtained.

Once a participant has agreed to enroll and have been consented/assented he/she will be informed of study group to which he/she has been randomly assigned. There are two options: 1) weight management alone or 2) weight management plus exercise gaming and entertainment experience. Randomization will occur at the group level (i.e., all consented/assented children in the Wed at 5 p group). Classes will be randomized in pairs of 2 and based on enrollment.

Treatment JOIN consists of 16 weekly Core in-person group sessions followed by 8 monthly mastery group sessions. While the JOIN Program continues for one year, the study will only occur over the first 16 weeks. YMCA sessions last 75 minutes and include a weight assessment of the child prior to each session. The groups are led by a YMCA facilitator. The topics for the first 16 sessions are listed below.

Child Activity Monitor. At sessions 1, 8, and 15 an actigraph will be distributed to each participating child in group 1 and 2. Each child will wear it for 1 week (7 days) during waking hours, and return it at the next session. An activity monitor provides no feedback to participants and provides an objective measure of physical activity (mild, moderate, vigorous) as well as sedentary behavior through downloaded data. The GT3XE Triaxial Activity Monitor w/Extended Memory® (produced by Actigraph) is a small, omni-directional accelerometer (Actigraph), which has already been approved by the FDA for measuring subject's physical activity, and energy expenditure level. The activity monitor (Actigraph) is a small, 1 inch by 1 inch, device that is worn at the hip level attached to an adjustable belt (also provided by the study). The belt can be worn below or above clothing.
