Warning on too much TV for kids
With a pre-emptive, prophylactic skin regimen, patients who receive panitumumab for treatment of metastatic colorectal cancer may be able to avoid some of the skin-associated toxicities, according to data presented at the 2009 American Society of Clinical Oncology Gastrointestinal Cancers Symposium in San Francisco. Edith Mitchell, M.D., a clinical professor in the Department of Medical

A team of researchers from the New South Wales Centre for Overweight and Obesity has determined that children and young teenagers who spend more than two hours a day in front of computers or televisions are significantly less likely to be fit.
The researchers, led by the University of Sydney’s Dr Louise Hardy, surveyed 2,750 11- to 15-year-old school students from New South Wales on their cardiovascular fitness and screen use and concluded that a child’s level of aerobic fitness is strongly associated with their level of ’small screen time’ and general sedentary behaviour.
The findings mark the first physiological evidence supporting the guidelines put forward by the American Academy of Pediatrics (AAP) in 2001 which were based on expert opinion and also suggested a two hour cap of sedentary behaviour for children.
“The AAP’s advice was essentially drawn from prudence. Our findings represent the first physiological link between more than two hours small screen recreation and lower aerobic fitness,” said Dr Hardy.
The researchers also found that girls were more likely to experience lower fitness as their sedentary behaviour increased compared with older boys whose fitness was less affected.
“We think these boys, who would be over fifteen years, probably have developed enough muscle mass which allows them to ’sit and be fit’,” Dr Hardy said.
“Still, it is important to understand most children need to exchange excess ’sitting time’ for ‘active time’ and limit any time in front of a screen to less than two hours a day in order to maintain fitness levels,” she added. “No screen days would be even better.”
Unlike previous studies, the researchers also included activities like reading, text messaging, doing hobbies and even homework in order to achieve a more inclusive representation of sedentary behaviour amongst children than just time spent in front of a television or computer.
The team’s research has been published in the February edition of the American Journal of Preventive Medicine.
If videogames like “Madden NFL” didn’t exist, 12-year-old Tom might go outside and toss around a real football - and he’d have a better chance of sprinting for a touchdown without getting winded. Too much small-screen recreation could undermine physical fitness, Australian researchers have found, in a new study that looks at how e-mail and

A vigorous 60-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while 90 minutes of weight lifting affects the level of only ghrelin, according to a new study. Taken together, the research shows that aerobic exercise is better at suppressing appetite than non-aerobic exercise and provides a

Regular exercise seems to reduce anger expression in overweight but otherwise healthy children, researchers said. The first published study on the topic looked at 208 typically sedentary 7- to 11-year-olds who participated in a 10-15 week afterschool aerobic exercise program or maintained their usual inactive routine. The Pediatric Anger Expression Scale, used to gauge common

People who use weight training to ease their lower back pain are better off than those who choose other forms of exercise such as jogging, according to a University of Alberta study. The study, done in conjunction with the University of Regina, showed a 60 per cent improvement in pain and function levels for people

Group exercise programs, treadmill training and horseback riding can be healthy choices for children with developmental disabilities, a new review of studies concludes. With these kinds of activities, children with disorders such as autism, mental retardation and cerebral palsy can improve their coordination and aerobic fitness, according to research analyzed by Connie Johnson, PT, a
