Hiding the TV remote and games console controller is a good thing to do to kids if it's the only way to limit the time they spend in front of a screen, according to a study published on October 11.
The study, published in the US journal Pediatrics, found that kids who spend hours each day in front of the TV or games console have more psychological difficulties like problems relating to peers, emotional issues, hyperactivity or conduct challenges, than kids who don't.
And contrary to what earlier studies have indicated, the negative impact of screen time was not remedied by increasing a child's physical activity levels, says the study conducted by researchers from the University of Bristol in Britain.
The researchers got 1,013 children between the ages of 10 and 11 to self-report average daily hours spent watching television or playing - not doing homework - on a computer. Responses ranged from zero to around five hours per day.
The children also completed a 25-point questionnaire to assess their psychological state, and the time they spent in moderate to vigorous activity was measured using a device called an accelerometer, which was worn around the waist for seven days.
The researchers found that children who spent two hours or more a day watching television or playing on a computer were more likely to get high scores on the questionnaire, indicating they had more psychological difficulties than kids who did not spend a lot of time in front of a screen. Even children who were physically active but spent more than two hours a day in front of a screen were at increased risk of psychological difficulties, indicating that screen time might be the chief culprit.
Earlier studies have found that while more time spent in front of a screen led to lower well-being, physical activity improved one's state of mind. That led researchers to believe that upping physical activity levels could counteract the negative impact of watching TV or playing on the computer.
