【medical-news】睡眠不足儿童容易发生肥胖
一项针对7岁儿童的研究表明，和过多的看电视以及缺少体育锻炼一样，每晚少于9个小时的睡眠会导致儿童超重和肥胖。
The study, being published Tuesday in the journal Sleep, also found that short sleep duration was associated with mood swings. The researchers had followed the subjects — 519 children in New Zealand — since birth, making periodic health and developmental assessments and interviewing their parents.
这个即将被发表在星期二《睡眠杂志》的研究也发现睡眠时间较短和心情变化有关。研究者们从婴儿出生开始跟踪调查了在新泽西的519名儿童，对他们作了周期性健康和成长评估并同时采访了他们的家长。
Sleep time did not affect I.Q. scores or measures of attention-deficit/hyperactivity disorder, but children who averaged less than nine hours’ sleep were significantly more likely than the others to be overweight.
睡眠时间并不影响智商得分或精力紊乱，但是那些每晚睡眠平均少于9个小时的儿童明显比别的儿童胖，
Using sleep monitors, the scientists discovered some other patterns in the 7-year-olds. On average, the children stayed awake for 48 minutes after they went to bed, and slept about a half-hour longer on weekdays than weekends. They slept the least in the summer: 40 minutes longer on winter nights, 31 minutes longer in the fall and 15 minutes longer in the spring. Having a younger sibling cost a 7-year-old an average of 12 minutes of sleep per night.
研究者们在对儿童的睡眠时间的跟踪调查的同时发现了7岁儿童的睡眠规律。他们在上床后还要保持平均48分钟的清醒，在平时比周末要多睡半个小时。他们在夏天睡眠最少：在冬天他们比在夏天多睡40分钟，秋天多睡31分钟，春天多睡15分钟。而且如果他们和兄弟姐妹一起睡的话，平均每一个兄弟姐妹会每晚干扰他12分钟的睡眠。
“The study is important from the perspective of providing another means of preventing the development of obesity,” said Ed Mitchell, the senior author and a professor of child health research at the University of Auckland. “At least in New Zealand — and it needs to be confirmed in other age groups — this seems to be an important factor.”
一位在奥克兰大学的资深儿童健康研究教授Ed Mitchell说：“这项研究在将来对于为防止儿童肥胖提供了另一个途径，至少对于新泽西的孩子来说。但这还需要在其他年龄的孩子身上证明－这看起来是一个很重要的因素。“ 多谢参与，还请编译一下，方便战友阅读。 谢谢版主给我加分！ [标签:content1][标签:content2]
