青春期肥胖危害大 或埋下癌症祸根

　　Being fat at 18 raises your chances of dying from cancer in later life, warn scientists.

　　科学家警告，如果在十八岁时肥胖，这将增加在今后生活中死于癌症的几率。

　　Men who were overweight or obese as teenagers were 35 per cent more likely to die from cancer as those who were a healthier weight, says a new study.

　　一项新的研究显示，那些在青春期体重超标或者有肥胖症的男性要比那些体重健康的人更有可能死于癌症。

　　Even losing weight during middle age did not appear to cut the extra risk of developing cancers such as lung, skin, kidney and prostate.

　　即便是在中年时期减轻体重，这也很难降低换上肺癌、皮肤癌、肾癌和前列腺癌的几率，此外还有中风的危险。

　　The research looked only at men, but women are likely to run a similar risk.

　　尽管这项研究的目标人群是男性，不过女性也具有相同的健康风险。

　　British experts behind the study of almost 20,000 men said the findings showed the importance of keeping a healthy weight throughout life.

　　英国的专家们在研究了20000男性之后，发现在一生之中保持健康的体重是件非常重要的事。

　　Medical Research Council (MRC) researcher Dr Linsay (correct) Gray, said it was the first time the impact of obesity in early adulthood on later risk of cancer had been closely examined.

　　医学研究理事会的研究院Linsay Gray博士表示，这次首次详细地研究青年时期超重与后期罹患癌症之间的联系。

　　Higher body mass index (BMI) - the scoring system of weight related to height - had been linked to several cancers, but always in later life, she said.

　　过高的身体质量指数，也就是体重与身高的比重，与日后得某些癌症有所联系。
