...secret that sedentary behavior contributes to obesity and chronically poor health. But not all sedentary behaviors are created equal, according to a new study that examines the link between blood pressure in children and their choice of inactive pastimes, including watching TV, using the computer and reading...
Researchers in the U.S. and Spain collaborated on the study of 111 children ages 3 to 8 and found that of all the forms of inactivity they examined, television-viewing was the worst. It was linked to significantly higher blood pressure in children - the more TV kids watched, the higher their blood pressure - and the effect held true regardless of whether a child was heavy or at a healthy weight. What's more, other sedentary behaviors, like using a computer, were not associated with similar blood-pressure hikes, according to the study, which was published in the Archives of Pediatric...
...These results show that sedentary behavior, and more specifically television-viewing, is related to blood pressure independent of body fat or obesity level," says Dr. Joey Eisenmann, a kinesiologist at Michigan State University and one of the study's co-authors...
...children were sedentary for five hours each day, and 1.5 of those hours were spent in front of a TV, computer or video game, on average. When the researchers further broke down screen time by activity, TV-viewing had the strongest correlation with higher blood pressure. Kids watching from 90 to 330 minutes of television each day had systolic and diastolic blood-pressure readings (the two numbers that indicate pressure caused by blood pumping from the top and bottom chambers of the heart, respectively) that were five to seven points higher than those of children watching less than half...
...first glance, the Obama Administration's Afghanistan policy doesn't seem to make sense. It is escalating military involvement in a conflict its own officials freely admit can't be won on the battlefield - and this despite the growing cost in blood and treasure and an awareness of the limited patience of the U.S. public for another open-ended counterinsurgency war. And this at the same time as some of the key diplomats tasked with handling the conflict are speaking openly of the need to integrate most of those fighting for the Taliban into Afghanistan's political order.
