Children with more than two hours of projection may have behavioral problems

Scientists have warned that two hours or more of screening per day could lead to behavioral and attention problems in children.

Earlier this year, it was reported that screen time for children under two had more than doubled in 17 years, from an average of 1.32 hours to 3.05 hours.

This indicates that many kids can spend more than three hours a day in front of smartphones, tablets and TV screens, but this could also impact their attention span.


A recent study, published in a scientific journal PLOS One, was conducted by researchers at the University of Alberta in Canada to study the impact of screen time on children's behavior.

Using data from the Canadian CHILD (Healthy Infant Development in Good Health) study, scientists evaluated information collected from nearly 2,500 five-year-olds and their families.

Parents involved in the study reported the time that their children spend in front of a screen every day.

According to the findings of the study, the children spent about an hour and a half in front of a screen at the age of three.

According to the Canadian Pediatric Society, the recommended daily time for three year olds in front of a screen in Canada is one hour.

At age five, children spend an average of 1.4 hours in front of a screen each day.

More than one in five (13%) children over five years has exceeded the recommended two-hour recommended screening period for the age group in Canada.

In addition to collecting information on the time that children spend in front of screens every day, the researchers also studied the behavioral patterns of children participating in the study.

The children's parents have completed a child behavior checklist, which is used to identify the emotional and behavioral problems of children and adolescents.

According to the researchers, children exposed to more time in front of a screen between three and five years of age were more likely to develop behavioral and attention problems than those who spent less time in front of a screen daily.

"This association was superior to any other risk factors we assessed, including sleep, parental stress, and socioeconomic factors," said Sukhpreet Tamana, first author of the study and postdoctoral fellow at the Department of Pediatrics's University of Alberta.

According to Piush Mandhane, associate professor of pediatrics and the university, the time spent in front of a screen has a "significant impact" on five-year-olds.

"The current Canadian guidelines do not provide for more than two hours of listening per day at this age, but our research suggests that it is even better to spend less time on the screen," adds the professor.

Tamana states that encouraging children to participate in organized activities could reduce the risk that they develop behavioral or attention problems.

"Very early on, organized activities are very important for young children," said the researcher.

"This paves the way for children's development, and I think instead of spending time in front of the screen, it would be beneficial for parents to increase opportunities for structured activities."

Les chercheurs de l'étude affirment qu'il est nécessaire de mieux comprendre si le type de contenu auquel les enfants sont exposés sur des écrans a des effets différents sur leur comportement.

Le professeur Mandhane ajoute que, selon leurs recherches, le "temps d'écran optimal" pour les enfants d'âge préscolaire est compris entre zéro et 30 minutes par jour.
