We developed a motion-controlled serious game for children that addresses 3 core topics of nutrition, physical activity, and stress coping. It is the first serious game that extensively targets the dietary energy density principle (DED-P) in relation to nutrition. The game is intended to provide an additional educational component for the prevention and treatment of obesity in children.<h4>Objective</h4>The Kids Obesity Prevention study aimed to evaluate the newly developed game and to evaluate how well children are able to understand and apply the DED-P.<h4>Methods</h4>This cluster randomized controlled trial collected data from 82 primary school children aged 9 to 12 years and theJournal of medical Internet researche15725https://www.ebi.ac.uk/biostudies/studies/S-EPMC7210499biostudies-literatureThe Kids Obesity Prevention Program: Cluster Randomized Controlled Trial to Evaluate a Serious Game for the Prevention and Treatment of Childhood Obesity.PMC7210499Schaeffeler NPeeraully RReiband NZurstiege GMack IEtges CGawrilow CWeimer KJunne FGiel KEEichhorn SBlumenstock GZipfel STeufel MfalseThe Kids Obesity Prevention Program: Cluster Randomized Controlled Trial to Evaluate a Serious Game for the Prevention and Treatment of Childhood Obesity.<h4>Background</h4>Health games provide opportunities for the treatment and prevention of childhood obesity.
