MUMBAI: Scientists now have an answer to a dilemma that every modern-day parent faces: is playing on the computer worse than watching television?
A paper from Michigan's Ann Arbor university presented at the American College of Cardiology's ongoing meeting in Washington said that TV is a bigger culprit as far as children's health is concerned. It said that children watching television for more than two hours or more daily were more likely to consume junk food and hence develop risk factors for heart problems in later life.
"While too much of both types of screen time encourages sedentary behavior, our study suggests high TV time in particular is associated with poorer food choices and increased cardiovascular risk," said the study's senior author Elizabeth Jackson.
A press release put out by the American College of Cardiology said sixth-graders who watched between two and six hours of TV a day were more likely to have higher body mass index, elevated systolic and diastolic blood pressure and slower recovery heart rate compared with those reporting low screen time or children who had comparable computer/video game use.
About 1,000 children studying in the sixth class of 24 schools were asked to name the type and frequency of screen time, snacking habits, and food and beverage choices in the last 24 hours. They were divided into three groups: low screen time (less than one-half hour a day), high TV time (two to six hours a day) and high computer/video games (two to six hours a day). The research found that children who spent more time in front of a screen - regardless of the type - snack more frequently and are more likely to choose less healthy snacks.
High TV viewers and computer/video game users both reported eating roughly 3.5 snacks a day - one full snack more than kids who had minimal exposure to these technologies. But children who watched two to six hours a day of TV were more likely than the high computer/video game group to eat high-fat foods such as French fries and chips.
The reason for snacking among children watching TV is perhaps the steady stream of commercials. The research paper added that children tend to have free hands while watching TV as opposed to when they are on the computer or playing video games, which provides more opportunity for mindless snacking
