"Up until now‚ most research about sitting and watching TV
has been focusedon children‚ while older adults have potentially the
most to gain from changingtheir behaviour‚" Gardiner said.
Researchers found that for each hour a person spends watching
TV‚ his orher risk of developing metabolic syndrome increases. Metabolic syndrome is acluster of cardiovascular disease predictors linked to the onset of type 2diabetes‚ according to a Queensland statement.
Other lifestyle factors linked to metabolic syndrome include a
lack ofregular exercise‚ poor nutrition‚ high alcohol consumption and smoking.
Gardiner said even light activity such while watching TV can reduce therisk of developing metabolic syndrome.
"Reducing sedentary behaviour may be a feasible and practical way for olderadults to improve their health and may be particularly important for those whosehealth or physical functioning limits their participation in moderate-intensityphysical activity‚" he said.
Previous studies had shown that sedentary behaviour has a niquephysiological effect on the body and that this was different from the effect oflack of exercise.
