Screen children’s screen time carefully, says WHO
Children aged 2 to 4 should not be allowed more than one hour of “sedentary screen time” per day and infants less than 1 should not be exposed to electronic screens at all, the World Health Organization said yesterday.
The United Nations agency, issuing its first such guidelines, said children under 5 should also be physically active and get adequate sleep to help develop good lifelong habits and prevent obesity and other diseases in later life.
Sedentary screen time would include watching television or videos and playing computer games.
“Healthy physical activity, sedentary behavior and sleep habits are established early in life, providing an opportunity to shape habits through childhood, adolescence and into adulthood,” the WHO said in the guidelines to member states.
Children between 1 and 4 years old should spend at least three hours in a variety of physical activities spread throughout the day. Infants under 1 should interact in floor-based play and avoid all screens, it said, adding being inactive is a “leading risk factor” for mortality and fuels the global rise in obesity.
In a report two years ago, the WHO said the number of obese children and adolescents worldwide had jumped tenfold to 120 million in the past 40 years and that the rise was accelerating in low- and middle-income countries, especially in Asia.
Excessive weight can lead to diseases including diabetes, hypertension and some forms of cancer.
Early childhood is a period of rapid physical and cognitive development during which habits are formed and family lifestyle routines are adaptable, it said in the guidelines, drawn from evidence in hundreds of studies, many from Australia, Canada, South Africa and the US.
“Sedentary behaviors ... are increasingly prevalent and associated with poor health outcomes,” the WHO said.
