丹麥科學家指出 體重超重對健康的危害變小
The study found the "moderately" overweight now had lower rates of early death than those who were normal weight, underweight or obese.
一項研究發現，相比於體重正常、體重過輕、以及體重過重的人來說，那些體重“適度”超重的人早死的機率要小一些。The work, published in JAMA, looked at many thousands of people's height, weight and death rates at three different time periods since the 1970s.
這項被刊載在JAMA上的研究，以成千上萬人的身高、體重和死亡率爲研究對象。自從上世紀70年代以來，該項研究在三個不同的時期記錄下了這些數據。In the mid-1970s, those with the lowest death rates were a normal weight and the obese faced a 30% higher risk of early death, the doctors, from Copenhagen University, found.
來自哥本哈根大學的教授們發現，在上個世紀70年代中期，那些體重正常的人的死亡率最低，而超重的人早死的風險要高出30%。
But now the threat to people's survival from being obese was now almost negligible
但是現在肥胖對人類生存的威脅幾乎可以忽略不計了。
The authors say the most likely explanation is that health systems are now much better at treating obesity-linked conditions, such as high cholesterol and blood pressure.
這項研究的作者們表示，對這一現象最有可能的解釋是，隨着現代醫療系統的顯著改善，由肥胖引起的高膽固醇和高血壓等病症更易於治療。Lead investigator Prof Borge Nordestgaard said: "Our results should not be interpreted as suggesting that now people can eat as much as they like, or that so-called normal-weight individuals should eat more to become overweight. That said, maybe overweight people need not be quite as worried about their weight as before."
項目組首席研究員博奇·諾德斯特教授說道：“我們的研究結果不應該被誤讀，它並不意味着現在人們可以隨心所欲地滿足自己的口腹之慾，也不意味着那些體重正常的人應該吃多一點來增重。這項研究結果的意義在於，現在肥胖的人也許不必再像以前那樣擔心自己的體重了。”The Danish researchers say their work shows a need to update the global categories that define excess weight, which are now two decades old.
這些來自丹麥的研究人員聲稱，他們的研究結果表明，目前全世界需要對肥胖定一個新的標準，因爲目前現行的體重分級標準已經是二十年前制定的了。But that idea was rejected by a British expert in metabolic medicine.
但是這一想法被一位英國專攻新陳代謝的醫學專家否決了。Prof Naveed Sattar, from the University of Glasgow, said: "These data are of interest, but they do not change advice we have been giving on obesity and its treatment and prevention. The current findings do not mean that being overweight is protecting you from death, far from it."
來自格拉斯哥大學的納瓦德·薩德爾教授說：“這些數據很有意思，但是它們不會改變我們對肥胖及其治療和預防的建議。目前的結果並不意味着超重可以讓你遠離死亡。”
