• Registration Number: NCT01523795
• Lead Sponsor: University of North Carolina, Chapel Hill

Brief Summary

The purpose of this study is to determine whether playing motion-controlled video games produces low caloric intake and higher caloric expenditure than watching TV or playing traditional video games.

Detailed Description

The purpose of this study is to investigate differences in behaviors and emotions during TV watching and video game playing. Participants will be randomized to either watch TV, play traditional button-based video games, or play motion-based video games for one hour while palatable snack foods and sugar-sweetened beverages are provided within easy reaching distance. Both energy intake as well as energy expenditure during a one-hour period will be measured. All three conditions will be optimized to resemble typical in-home conditions as much as possible.

An additional goal of this study is to provide insight into the possible pathways by which TV and video games differentially affect intake and expenditure. Distraction from the real world (also called presence or engagement) will be analyzed to determine if a) these variables differ across groups and b) if these variables explain differences in energy intake and/or expenditure. The TV group will watch TV shows using Netflix streaming service, which will allow them to choose from a variety of popular shows without viewing commercials. As the investigators are primarily interested in satiety and hand occupation effects, the lack of commercials will allow us to eliminate food advertisements as a causal factor.

Finally, the third major goal of the study is to investigate how young adults choose screen-based media. In the two video game arms, participants will be allowed to choose to play any of 10 provided games, and in the TV group, participants will be able to choose from hundreds of options. Choices of game/program, time spent on each game/program, and psychological reactions to each game will be measured and analyzed.

Arm && Interventions

Group	Intervention	Description
Motion-controlled video gaming	Motion-controlled video gaming	Participants played motion-controlled video games that involved at least throwing, hitting, or dancing motions using a Wii or Xbox 360 console for one hour
Traditional video gaming	Traditional video gaming	Participants played traditional (handheld gamepad controller-based) video games using a Playstation 3 console for one hour
Television watching	Television watching	Participants watched television via Netflix instant streaming for one hour

Primary Outcome Measures

Name	Time	Method
Energy intake	One-hour study period	Energy intake was measured by weighing available food and beverage containers before and after one-hour period in which participants watched TV/played video games, then calculating the differences in weights

Secondary Outcome Measures

Name	Time	Method
Energy expenditure	One-hour study period	Energy expenditure was measured using a Sense Wear Pro armband, which uses accelerometry and galvanic skin response to estimate metabolic equivalents
