青春期肥胖危害大 或埋下癌症祸根

　　Dr Gray said ‘It is very interesting that higher BMI at age 18 actually leads to a greater risk for cancer than higher BMI in middle age.

　　Gray博士说：“值得注意的是，在18岁时较高的身体质量指数要比在中年时期出现这一情况引发癌症的几率高很多。”

　　‘The message here is really clear: keeping your weight healthy as a young adult can significantly reduce your chance of developing cancer.

　　“这点是很明确的，在亲年时期保持健康的体重对于预防癌症有着至关重要的作用。”

　　In the study, MRC researchers in collaboration with researchers at University College London and Harvard School of Public Health, Boston, analysed the medical records of 19,593 male graduates who attended Harvard between 1916 and 1950.

　　在这项研究中，英美两国的健康专家联袂合作，研究了在1916年到1950年间毕业于哈弗大学的19593男学生的医疗记录。

　　They found that men in the study who had the highest BMIs at age 18 were 35 per cent more likely to die from cancer than those with lower BMIs.

　　研究者们发现，在18岁时高身体质量指数会增加35%死于癌症的风险。

　　The link between teenagers who were overweight and later cancer was particularly strong for lung, skin, oesophageal, kidney, bladder, prostate and testicular cancers.

　　青春期体重超标与后期出现肺、皮肤癌、食道、肾、膀胱、前列腺和睾丸方面的癌症的两者之间有着紧密联系。

　　For example, men whose BMI was greater than the average score of 21.7 (which was still in the healthy range) at age 18 had more than a 50 per cent greater risk of dying from lung cancer than those with the lowest BMIs, even after accounting for whether or not they smoked.

　　例如，在18岁时身体质量指数超过平均水平数值21.7（同样属于健康范围）的男性要比那些底数值的人死于肺癌的风险增加了50%，而且吸烟与否对于此都没有影响。

　　The study found a man’s changes in BMI between early adulthood and middle age did not affect the risk, says a report in the journal Annals of Oncology (must credit).

　　研究还发现，青年与中年时期的身体质量指数的变化对于患病的风险的影响也相当有限。
