简要总结
The purpose of the study is to test the effects of different versions of active video games (AVGs) on body composition, cardiometabolic risks, and cognitive functions among overweight/obese children over 6 months.
详细描述
The study aims to explore the effects of narrative-enhanced AVG on (1) body composition, (2) cardiometabolic risks, and (3) cognitive functioning among overweight/obese 8-12 years old children over 6 months.
A total of 210 children will be recruited from Tufts Floating Hospital, Boston Children's Hospital, and Martha Eliot Health Center. The investigators divided the participants into three groups to evaluate the effect of using active game consoles and stories to motivate children to exercise: A third of them have standard clinical care only; a third of them have the same standard clinical care plus an Xbox and active games; the remaining third of them have the same standard clinical care, an Xbox and active games, plus the stories delivered to their Xbox consoles.
Each child, accompanied by their guardian, will be asked to visit the Northeastern University Exercise Science Laboratory over the 6-month period. Blood samples, body composition (using Dual-energy X-ray absorptiometry, or DEXA Scan), and cognitive and affective evaluations of the active video games (AVGs) will be collected. Additionally, parents will be asked to fill out questionnaires related to their child's physical activity behaviors. Children would also be required to wear two accelerometers (essentially, a "smart watch" or activity tracker) on their wrist and waist for 7 consecutive days after the three visits within the 6 months.

结局指标
主要结局
Changes in fat%
时间窗: 6 months
Measured through dual-energy X-ray absorptiometry (DEXA) scan by GE Lunar Prodigy (GE Healthcare, Chicago, IL).
Changes in objective child physical activity
时间窗: 6 months
Physical activity will be measured with two 7-day accelerometer worn on the wrist and hip after three visits over 4-6 weeks, including minutes/day MVPA total. Physical activity and time spent in moderate to vigorous physical activity will be measured by two triaxial accelerometer (Actigraph Link and Actigraph GT3X+, Actigraph, Ft. Walton Beach, FL). Children will be asked to wear them for 7 full days during periods.
