Too much television may increase future cardiovascular risk for children.HealthDay (4/20, Doheny) reported, "Young children who spend too much time watching TV or playing computer games have narrower eye arteries than kids who are more physically active," according to a study published online in Arteriosclerosis, Thrombosis and Vascular Biology: Journal of the American Heart Association. "Narrower arteries are a marker of future cardiovascular risk, and the narrower the vessels, the higher the risk," according to the researchers.
WebMD (4/20, Boyles) reported that "the study included close to 1,500 6- and 7-year-olds living in Sydney, Australia. The children's parents completed questionnaires designed to assess how much time the kids spent watching TV or using other electronic equipment and how much time they spent engaging in physical pursuits." In addition, "digital photographs were taken in the back of each child's eyes to determine the width of the retinal blood vessels."
