American kids spend an average of four to five hours per day on “screen time”—watching TV, playing video games or using a computer. As a result, youth engage in less physical activity and they are also exposed to more fast-food and sugary beverage advertisements. Many aspects of the social, cultural and socioeconomic environments influence how children perceive of healthy eating and active living. These factors must be identified and their impact minimized to improve the health of our nation’s children.
