New research suggests children who spend longer than two hours per day in front of a computer or television screen are at risk to suffer psychological difficulties, regardless of how physically active they are.
UK scientists studied over 1,000 children aged between 10 and 11, measuring the time children spent in front of a screen as well as their psychological well-being. The research effort is termed The PEACH project.
In addition, an activity monitor recorded both children’s sedentary time and moderate physical activity. The results showed that more than two hours per day of both television viewing and recreational computer use were related to higher psychological difficulty scores, regardless of how much time the children spent on physical activity.
The authors of the report, published in the November edition of the journal Pediatrics, conclude that limiting children’s screen time may be important for ensuring children’s future health and well-being.
According to the activity monitor, the children in the study who spent more time sedentary had better psychological scores overall.
Those children who did more moderate physical activity fared better in certain psychological areas, including emotional and peer problems, but fared worse in some areas related to behavior, including hyperactivity.
Lead author Dr. Angie Page from the University of Bristol’s Centre for Exercise, Nutrition and Health Sciences said: “Whilst low levels of screen viewing may not be problematic, we cannot rely on physical activity to ‘compensate’ for long hours of screen viewing.
“Watching TV or playing computer games for more than two hours a day is related to greater psychological difficulties irrespective of how active children are.”
Children’s psychological well-being was assessed on the basis of a strengths and difficulties questionnaire which rated their emotional, peer, conduct and hyperactivity problems.
The children were asked to rate a series of statements as true on a three-point scale, varying from not true, to somewhat true to certainly true.
Statements to assess their emotional wellbeing included; ‘I am often unhappy, down-hearted or tearful’, while statements to assess their peer problems included; ‘I am usually on my own’, ‘I generally play alone or keep to myself’.
