大腹便便者 易患结肠癌

Bigger Waist, Bigger Colon Cancer Risk
腰围越大，结肠癌风险越大

Obesity -- Especially Abdominal Obesity -- Increases Colon Cancer Risk
肥胖-尤其是腹部肥胖-使结肠癌风险增加

Sept. 7, 2007 – The bigger your waistline, the bigger your risk of colon cancer.
2007年9月7日-腰围越大，结肠癌的风险越大。

This finding, from an analysis of 30 long-term studies of colon cancer, reinforces the link between obesity and colon cancer in men and, to a lesser extent, in women. Obesity, the study shows, boosts the risk of rectal cancer in men but not in women.
这一结果由30个长期结肠癌研究分析而来，强调了男性肥胖与结肠癌的联系，女性影响程度较小。研究显示，肥胖使男性、而不是女性的结肠癌风险增加。

Perhaps most importantly, the study suggests that belly fat is more relevant to colon cancer risk than fat in other places. For every 4 inches gained around the waist, the risk of colon cancer goes up 33% in men and 16% in women.
或许最重要的是，研究表明，与其他部位相比，腹部脂肪增多与结肠癌风险相关性更大。腰围每增加4英寸，男性结肠癌的风险升高33%，女性为16%。

\"Abdominal obesity was more strongly related to increased colon cancer risk than was overall obesity,\" report study researchers Susanna C. Larsson, MSc, and Alicja Wolk, DMSc, of the Karolinska Institute in Stockholm, Sweden.
瑞典斯德哥尔摩卡罗林斯卡学院研究员Susanna C. Larsson 称，\"与整体肥胖相比，腹部脂肪堆积和结肠癌风险增高更为相关\"。

It's not clear why obesity is more likely to cause colon and rectal cancer in men than in women. 目前还不清楚为什么肥胖更容易引起男性结肠癌和直肠癌。

The findings appear in the September issue of the American Journal of Clinical Nutrition.
该研究结果刊登于《美国临床营养杂志》九月号。
