LONDON, Oct 19 (Reuters) - A trend for children and adolescents to stay up later and sleep less may be linked to rising levels of obesity, according to a review of existing research published on Thursday.
Bristol University researcher Shahad Taheri said televisions, computers, mobile phones and other gadgets should be banned from children's bedrooms to enable them to get a good night's sleep.
Writing in the journal Archives of Disease in Childhood, Taheri said there was increasing evidence that shortened sleeping times result in metabolic changes that may contribute to obesity, insulin resistance, diabetes and heart disease.
A UK study published last year indicated that insufficient sleep in infants aged 30 months was associated with obesity by the time they reached the age of seven.
Taheri said this suggested that sleep loss at a young age may alter the body's mechanisms that regulate appetite and energy expenditure.
Limited sleep is also a problem for teenagers, whose need for sleep increases during the critical years of adolescent development.
Other research, published by Taheri in 2004, found that adults sleeping only five hours had almost 15 percent higher levels of ghrelin -- a hormone released by the stomach to signal hunger -- than those managing eight hours.
The same group of short sleepers also had more than 15 percent less Leptin, a hormone produced by fat tissue when energy levels are low.
Children waking up tired from not enough sleep were also likely to take less physical exercise, adding to the likelihood of putting on weight, Taheri said.
They would miss the beneficial effects of physical activity, not least its tendency to lead to better sleep.
"Sleep is probably not the only answer to the obesity pandemic," Taheri said.
"But its effect should be taken seriously, as even small changes in energy balance are beneficial."
He said children should observe regular sleeping and waking times, avoid large meals at bedtimes and have a quiet dark bedroom that was neither too hot nor cold.
Adolescents should be allowed to sleep in longer at weekends, but no more than two to three hours beyond normal waking time, as this disrupts the body's internal clock.

LONDON, Oct 19 (Reuters) - A trend for children and adolescents to stay up later and sleep less may be linked to rising levels of obesity, according to a review of existing research published on Thursday.
回顾最近发表的研究结果显示睡眠时间的短缺可能增加儿童和青少年肥胖患病。
Bristol University researcher Shahad Taheri said televisions, computers, mobile phones and other gadgets should be banned from children's bedrooms to enable them to get a good night's sleep.
布尼斯托儿大学研究员shahad taheri说为了儿童有一个好的睡眠，儿童房间应不放置电视、电脑、手机以及其它小玩意。
Writing in the journal Archives of Disease in Childhood, Taheri said there was increasing evidence that shortened sleeping times result in metabolic changes that may contribute to obesity, insulin resistance, diabetes and heart disease.
发表在儿科杂志 Archives of Disease in Childhood的论文中，Taheri认为越来越多的证据显示儿童睡眠时间的缩短导致代谢变化，这些变化可引起肥胖、胰岛素抵抗、糖尿病和心脏病。
A UK study published last year indicated that insufficient sleep in infants aged 30 months was associated with obesity by the time they reached the age of seven.
去年英国的一项研究结果显示30个月大小的婴幼儿睡眠短缺与患儿7岁时出现肥胖存在相关性。
Taheri said this suggested that sleep loss at a young age may alter the body's mechanisms that regulate appetite and energy expenditure.
Taheri说这些结果说明年幼时期睡眠缺乏可以改变调节机体食欲和能量消耗的代谢过程。
Limited sleep is also a problem for teenagers, whose need for sleep increases during the critical years of adolescent development.
对于十几岁处于青春发育期需要增加睡眠的青少年而言，睡眠短缺也是一个问题。
Other research, published by Taheri in 2004, found that adults sleeping only five hours had almost 15 percent higher levels of ghrelin -- a hormone released by the stomach to signal hunger -- than those managing eight hours.
2004年Taheri的另一项研究结果显示睡眠时间少于5小时的成人较睡眠时间8小时的成人ghrelin分泌水平高15％，这是一胃分泌的饥饿信号激素。
The same group of short sleepers also had more than 15 percent less Leptin, a hormone produced by fat tissue when energy levels are low.阅读本文的人还阅读：
