Video Games, Obesity, and Children

To examine associations between video game play and obesity in children. Based on a scoping review of 26 studies (25 cross-sectional; 1 longitudinal) published in 2013–2018, 14 studies (53%) reported no association between video game play and obesity, and 12 studies reported positive associations. In a review of 8 systematic reviews, there was preliminary evidence on the effectiveness of exergame (physically active) play for weight reduction and to attenuate weight gain but little indication that interventions effectively reduced video game play or general screen time. This review found ambiguous evidence on the extent to which video game play is or is not significantly associated with obesity in children and preliminary evidence of exergame play as a tool for weight reduction and attenuation of weight gain. Several gaps existed in understanding the relationship between video game play and obesity, and prospective and interventional trials are needed.
