A good night’s sleep in the early years of life could be very important in preventing a child becoming obese, say scientists. Babies and pre-school children who sleep for less than ten hours a night are more likely to be overweight when they are older, research has found. Experts believe that those who do not get enough sleep are more likely to feel hungry and want more calorie-rich food during the day. Former research has linked sleeping with obesity in adults and teenagers, but this is one of the first to look at very young children. Researchers from the Universities of Washington and California looked at the sleeping habits of almost 1,000 children under the age of five. They found those who had less than ten hours’ sleep were twice as likely to be overweight five years later. Childhood obesity has doubled over the past 10 years. A quarter of secondary school pupils are now judged to be so overweight that their health is in danger. Experts believe sleep, or lack（缺乏）of it, could be a major cause of this. On average children are sleeping for an hour less than they did 30 years ago. Last year Chinese researchers looked at more than 5,000 youngsters and found that those who were able to catch up on （补充）sleep at the weekend were far less likely to get body weight problems. Scientists have also found a link between lack of sleep and diabetes（糖尿病）. Last year Canadian researchers discovered those who did not get seven or eight hours’ sleep a night were two and a half times more likely to become sick. 小题1:The underlined word “obese” in the first paragraph may mean .
