Kids' 'screen time' linked to early markers for cardiovascular disease

April 21, 2011

Children who had the most hours of screen time, particularly in front of the television, had narrower arteries in the eyes -- a possible indicator for future heart disease risk, according to a new study. Children with the highest levels of physical activity had wider retinal arterioles. The magnitude of vessel narrowing for each hour of screen time was similar to a 10 millimeter of mercury rise in systolic blood pressure.
