Globally, nearly 43 million children under 5 are believed to be overweight or obese, according to figures from the World Health Organization (WHO). In an attempt to eradicate this scourge, researchers are trying to identify its risk factors. The simple fact that the youngest sit in front of the television would be part of it, according to a new study by researchers at the University of South Australia (Australia). In fact, staying in front of a screen would increase the risk of developing childhood obesity more than playing video games, for example.
2.5 to 3 hours of television per day
For this study, published in theObesity Research & Clinical Practice At the end of 2018, scientists assessed the sedentary behaviors of 234 Australian children aged 10 to 13. Of these, 130 were at a healthy weight, while 104 were considered obese. The Australian University team examined the impact of different so-called “sitting” behaviors, such as watching television, playing video games or on the computer, sitting down to eat or traveling in a car.
In the end, the young people passed more than 50% of their day sitting (not counting sleep). On average, they rwatched television 2.5 to 3 hours a day. And this activity has been shown to be the inactive behavior most associated with obesity, in both boys and girls.
“It is not surprising to see that the more a child is inactive, the more his risk of overweight increases, comments in a press release the author of the study, Dr. Margarita Tsiros, but not all sedentary behaviors are created equal when it comes to children’s weight. This research shows that the time they spend sitting is less important than what they do when they remain seated. For example, certain types of activity are more strongly associated with body fat in children than others, and time spent watching television seems to be the worst offender. “
Serious health problems
However, differences seem to emerge between boys and girls. Boys tended to watch television more, at the rate of 37 minutes per day, but they also spent more time playing video games. “Boys who sit for more than 30 minutes can also have a higher body fat mass, so it’s important to monitor screen time and sitting to make sure they’re taking regular breaks.”, adds the doctor.
The researchers point out that an overweight child has an increased risk of developing serious health problems, such as type 2 diabetes, high blood pressure or cholesterol. He may also face social and self-esteem issues, as well as difficulty doing certain activities. “An overweight child is more likely to become an overweight adult. It is therefore essential to fight against unhealthy behavior in childhood ”, concludes Margarita Tsiros.
