无论在发达国家还是发展中国家,体重超重(BMI>25kg/m~2)和肥胖(BMI>30kg/m~2)都是一个必须面对的公共卫生问题。越来越多的证据表明超得/肥胖增加了某些癌的危险性,包括前列腺癌、结直肠癌、乳腺癌(绝经后期妇女)、子宫内膜癌、肾癌及胆囊癌等。2002年1月在瑞士日内瓦的一次关于膳食、营养和慢性疾病预防的WHO/FAO专家咨询会上,分析了膳食因素如蔬菜和水果、超重/肥胖、酒精等与癌的危险性方面的证据,结果表明超重/肥胖和癌的危险性关系的证据最充分(convincing)。WCRF/AICR(世界癌症研究基金会/美国癌症研究所,1997)的报告分析了肥胖与癌症危险性关
In both developed and developing countries, overweight (BMI> 25 kg / m 2) and obesity (BMI> 30 kg / m 2) are all public health problems that must be addressed. There is increasing evidence that excess / obesity increases the risk of certain cancers, including prostate, colorectal, breast (postmenopausal women), endometrial, renal and gallbladder cancers. At a WHO / FAO expert consultation on the prevention of diet, nutrition and chronic diseases in January 2002 in Geneva, Switzerland, evidence of the risk of dietary factors such as vegetables and fruits, overweight / obesity, alcohol and cancer was analyzed. The results show that the evidence of the risk of overweight / obesity and cancer is most convincing. The WCRF / AICR (World Cancer Research Foundation / American Cancer Institute, 1997) report analyzes the relationship between obesity and cancer risk
