US kids spend too much time in front of a screen and too little asleep, study finds

• Only 5% meet sleep, exercise and screen time guidelines
• Sleep and screen findings linked to drop-off in cognitive skills

Only one in 20 kids in the United States meets guidelines on sleep, exercise and screen time, and nearly a third are outside recommendations for all three, a new study has found.

On average, children aged eight to 11 spent 3.6 hours a day glued to a TV, mobile phone, tablet or computer screen, nearly double the suggested limit of two hours, researchers found.
