A snapshot of Australian 11- and 12-year-olds has found that it is not unusual for them to spend up to 11 hours a day seated.听By comparison, their parents spend nine hours听sitting still.

This is according to new research conducted by the , conducted jointly with the .

The听Child Health CheckPoint study examined physical activity and听sedentary behaviour of 1261 children aged 11鈥�12 and 1358 of their parents over one week.听

Professor Timothy Olds of University of South Australia鈥檚 (ARENA) said the results, published in , show that Australian children have听high levels of sitting and only modest levels of physical activity.

鈥淧revious Australian research found high levels of sedentary time tended to comprise about 40% screen time and 25% sitting at school, with the rest taken up with sedentary social听occasions, eating and passive transport,鈥� Prof Olds said.

鈥淗ours spent watching TV use may be a marker of general household dysfunction, poor routines听and less emphasis on health. The more hours of TV, the worse outcomes across the board 鈥� from听blood pressure to academics and quality of life,鈥� he said.

According to the Australian Government鈥檚 Physical Activity and Sedentary Behaviour Guidelines,听children aged five to 12 years should get at least 60 minutes of moderate to vigorous physical activity听daily, while those aged over 18 years are advised to do a minimum 30 minutes at least five times a听week. The guidelines also encourage people to break up long periods of sitting and to limit screen听time for children in this age group to no more than two hours a day.

Other听key CheckPoint findings include:

• The children of overweight parents are not destined to inherit their parents鈥� weight problems.
• Pre-teens and middle-aged adults are usually getting the recommended amount of sleep but they aren鈥檛 always sleeping soundly.
• Big snacking parents may inadvertently influence their children to eat more.
• A parent鈥檚 lung and bone health all have an impact on their child by the age of 11 or 12.
