Screen time predicts delays in child development, says new research

Experts recommend no screen time for new-born kids up to two-year-olds

"Early exposure to excessive screen time at 24 months was predictive of lower developmental outcomes at 36 months", said Dr. Skyler Kalady, of the Cleveland Clinic.

Researchers say a pattern quickly came into focus: the more time children spent in front of their devices, the worse they did on tests.

One in four Canadian children are starting their school years inadequately prepared for learning and a newly published study led by the University of Calgary shows that excessive screen time is a key contributor to this growing problem. For example, when children are observing screens without an interactive or physical component, they are more sedentary and, therefore, not practicing gross motor skills, such as walking and running, which in turn may delay development in this area. The research looked into the screen habits and cognitive development of kids who spent two to three hours per day on a gadget.

Another reason screen time can slow development is that the hours passed in front of televisions and tablets mean kids may miss out on chances to scribble with crayons or play games that help them learn how to kick a ball or take turns. "This exceeds the recommended guidelines of no more than one hour of high-quality programming for kids between the ages of 2 and 5" set by the American Academy of Pediatrics (AAP).

"We can't say that increased screen time causes delays in child development, but I think we get as close as we can, in an observational study, [to] saying that there is a link here", she says. They analyzed how much screen time the children received, and how they fared on developmental screening tests, at ages two, three and five.

Although the researchers did not examine the relationship between screen time and developmental outcomes numerically, they found "a stable association" between screen time and child developmental screening test scores that was not accounted for by other factors, according to the study. "Specifically, how screen time when children are two years of age impacts development at three years, and how screen time at three years impacts development when kids are five", says Madigan, who holds a Canada Research Chair in the Determinants of Child Development. Lastly, the authors noted that it is possible that since the study was conducted, technology has evolved, causing media consumption to change and have different effects on youth.

"Screen time should at least be an educational experience, not just a shiny distraction", Dimitriu said.

"Is too much screen time a culprit in creating these disparities in learning?" The way in which children are using TV or computers is also important. Our suggestion is to treat screen time like we do junk food with kids: "A little is OK, but too much is a problem", she said.

More than 2,400 children were included in the analysis. Mothers also reported the range of time their children spent using screen devices on a typical weekday and weekend day.

Researchers recommend families prepare a media plan including rules for when devices can be used and for how long.

The issue of whether screen time is bad for children has become a battlefield. Children benefit when parents devote more attention to them rather than relying on devices to occupy or calm them down.
