近期，一项研究结果称，睡眠工夫关乎腰围，如果年轻人睡眠过少或过多，腰身脂肪在一段时期后会明显增加。 Younger adults who get either little sleep or a lot of it may see a greaterexpansion in their waistlinesover time, a study published suggests.
研究人员发现，5年后，在年龄低于40岁的非洲裔美国人和拉丁裔美国人成年人中，每晚平均睡眠工夫不超过5小时的研究对象将比平均睡眠6、7个小时的人积累更多腹部脂肪。 Researchers found that among black and Hispanic adults younger than 40, those who typically slept for five hours or less each night had a greateraccumulation of belly fat over the next five years, versus those who averaged six or seven hours.
而每晚卧床工夫不低于8小时的人同样会导致脂肪增加--但情况要比睡眠过少者乐观。 Those who logged eight hours or more in bed each night also showed a bigger fat gain - but it was less substantial than that seen in "short sleepers."
该研究结果刊载于医学杂志《睡眠》中。研究并没有证明睡眠过少或过多会直接导致过量脂肪增加。但它对其他研究做了数据支持和延伸--特别是缺少睡眠--将睡眠持续工夫和体重增加、糖尿病、心脏病等做了关联。 The study, reported in the journal Sleep, does not prove that too little or too much sleep directly leads to excess fat gain. But the findings support and extend those of other studies linking sleep duration - particularly a lack of sleep - to weight gain and even to higher risks of diabetes and heart disease.
该研究以332名非洲裔美国人和775名拉丁裔美国人为研究对象，他们年龄在18至81岁之间。起初，所有报告都是关于他们的睡眠习惯、饮食、锻炼及其他生活因素。研究开始的时分，研究人员便用CT扫描方式测出研究对象腹部脂肪含量。五年后再做一次检测。 The study included 332 African-American and 775 Hispanic-American men and women ages 18 to 81. At the outset, all reported on their sleep habits, diets, exercise levels and other lifestyle factors. The researchers used CT scans to measure participants'abdominal fat, at the start of the study and again five years later.
