It's an oft-heard lament that children spend far too much time watching TV, DVDs or playing video games - and a study suggests an alarming number of babies are being turned into "screen time" junkies as well.
In a study of more than 1,000 families, U.S. researchers found that 40 per cent of three-month-olds and about 90 per cent of kids aged two years or younger regularly watch television, DVDs or videos.
The study found the infants and toddlers were spending up to 1 1/2 hours a day viewing television shows or DVDs, an activity the researchers say can be harmful to cognitive development.
Study co-author Dr. Dimitri Christakis, a pediatrician at Children's Hospital in Seattle, said certain TV programs and infant-aimed videos such as Baby Einstein and Brainy Baby are marketed as being advantageous for the developing child.
"What we know is that the claims that are made by the purveyors of these products, both explicitly and implicitly, that they can make your children smarter or more musical or more mathematical, are entirely unsubstantiated," he said Monday from Seattle.
"There's absolutely no scientific evidence in support of those claims, nor is there any scientific basis theoretically to believe them," said Christakis, co-author of the book The Elephant in the Living Room: Make Television Work For Your Kids.
"And the best available evidence to date suggests that certainly watching a lot of TV before the age of two is in fact harmful - harmful in terms of children's attentional abilities later in life, harmful in terms of their cognitive development, both of those measured at school entry."
Even the TV program Sesame Street, which has been shown as beneficial for number and letter recognition among three- to five-year-olds, is associated with language delays when viewed by children under three, he said.
"Sesame Street wasn't designed for kids that young, but it's watched by kids that young because parents think if it's good for a three-year-old, it's good for a two-year-old. And parents want to believe their one-year-old is as advanced as the average three-year-old."
To conduct the study, published in today's issue of the Archives of Pediatrics and Adolescent Medicine, the researchers conducted a telephone survey of 1,009 parents of children age two to 24 months. They analyzed four television and DVD content categories: children's educational, children's non-educational, baby DVDs/videos and adult television (such as talk shows or sports programming).
On average, children began watching TV at nine months old, with an average viewing time of 40 minutes a day. Those who began getting screen time at three months of age watched less than an hour per day, and by age 24 months they were watching more than 1.5 hours per day.
Parents watched with their children more than half the time.
"The results show only 32 per cent of parents report watching television or videos with their child every time the child watches," the authors write.
Christakis said parents have several reasons for allowing television and DVD/video viewing: 29 per cent believe that television is educational or good for their child's brain; 23 per cent see it as enjoyable or relaxing for their child; and 21 per cent think it gives them time to get things done while the child is entertained.
"People have the assumption that parents used this as a babysitter, that's their primary motivator," he said. "But in fact what we found was that the No. 1 reason they give is that it's good for their children's brain."
The Canadian Pediatric Society recommends that preschoolers watch an hour or less of TV a day and that school-age kids keep their screen time to two hours maximum.
