The time children and teens spend video gaming, scrolling through social media or watching TV could be putting their future heart health at risk, a new study says.
Each additional hour of screen time is associated with an increase in heart risk factors like blood pressure, cholesterol and blood sugar levels, researchers reported today in the Journal of the American Heart Association.
"It's a small change per hour, but when screen time accumulates to three, five or even six hours a day, as we saw in many adolescents, that adds up," lead investigator David Horner, a researcher at the University of Copenhagen in Denmark, said in a news release.
"Multiply that across a whole population of children, and you're looking at a meaningful shift in early cardiometabolic risk that could carry into adulthood," Horner added.
