In what is likely to be no surprise to parents, the news about kids and screen time keeps getting worse. In a recent issue of JAMA Pediatrics, two studies — an original study done in New York State and a research letter from investigators in Canada — looked at what affects how much time young children spend in front of a screen, and whether children continued their screen viewing habits as they entered school. Together they paint a worrying picture of younger and younger children spending more and more time in front of phones, laptops and televisions.
Children’s average daily screen time increased from 30 minutes at 12 months of age to 120 minutes at age 36 months, the team on the New York State study found, despite the fact that screen time among two- and three-year-olds has been shown to negatively affect mental health.
The Canadian researchers reported that nearly 80 percent of two-year-olds and over 94 percent of three-year-olds did not meet screen time guidelines from the World Health Organization (WHO) and the American Academy of Pediatrics (AAP).
Parents should develop a family media plan in order to make rules around screen use clear and consistent.
It is also possible that parents are simply not aware the guidelines exist. “When I talk to parents and say the screen time guidelines for preschoolers are one-hour of high-quality programming per day, many are surprised,” Madigan said. So healthcare providers should make sure parents are aware of the guidelines. They can also work with families to develop a family media plan about digital media use in the home that applies to both parents and kids.
First-time moms were more likely to have children whose screen time increased up to age three, and children whose screen time increased during their first three years were more likely to have a greater amount of screen time at age eight, according to the New York study. It also found that being a woman and parents with a graduate-level education, versus having a college education, were associated with a lower risk of increasing screen time.
Mothers' screen time and being cared for at home rather than at a daycare center were two factors that made it more likely young children would exceed screen time guidelines, the Canadian team indicated, but fathers weren't included in their study. Going forward, the researchers would like to take a closer look at the effects of dads’ screen time. “We’d like to hear from dads. In this study we only followed moms because they were the primary participants in our sample,” said Madigan. Since parents’ screen time is important for understanding children’s screen use, she added, it’s important to examine dads' screen time, too.
Families can also decide where and when screens can be used. “For example, we recommend they be used in a common area, rather than children’s individual rooms, and that they not be used within an hour of bedtime, because screens can be very stimulating and keep children awake,” Madigan, an associate professor of psychology at the University of Calgary, said.
Madigan is also the co-author of an editorial, also in JAMA Pediatrics, about the pros and cons of digital media, and the responsibilities clinicians and researchers have when they advise families about children’s digital media use.
