BMC Med:悲伤……BMJ子刊揭示:肥胖致癌,男女有别!

众所周知,病从口入:管不住嘴也迈不开腿的人,多是肥胖型选手,而肥胖又会增加多种以结直肠癌为代表的癌症风险。

众所周知,病从口入:管不住嘴也迈不开腿的人,多是肥胖型选手,而肥胖又会增加多种以结直肠癌为代表的癌症风险。

日前,基于分子诊断的2020版《中国体检人群结直肠癌及癌前病变白皮书》发布。该《白皮书》较全面地反映了国民肠道健康现状。

在75229个样本人群中,阳性人数为6776人,占比9.01%,与2019年的8.93%比,整体阳性率略有上升。从性别分布来看,男性肠道健康问题更为严重,其原因可能与男性生活方式不规律、吸烟饮酒频率较高有关。

从阳性率来看,国人肠道健康状况也呈现出一定的地域分布特点。结果显示,南方阳性率高于北方;西部阳性率最高,其次为东部、东北、中部地区。

让我们再来看看其他相关研究。

发表在《BMC Medicine》上的一项新研究中,由英国布里斯托大学与国际癌症研究机构领导的研究团队调查了不同的体脂测量方法对男性和女性结直肠癌风险的影响。这项涉及超过10万人的大型研究发现,较高的身体质量指数(BMI)对男性风险更大;而较高的腰臀比(腰围除以臀围,测量腹部脂肪)对女性风险更大。

在这项新研究中,研究人员分析了肥胖与结直肠癌风险的性别和身体部位特异性的联系,以及肥胖相关代谢物是否可以解释肥胖与结直肠癌的关联。将包括BMI、腰臀比和靶向代谢组学的123种代谢物的遗传变异作为指标,研究人员使用了孟德尔随机化法对具有结直肠癌风险的BMI和腰腿比进行了性别组合和性别特异性研究。研究对象来自结直肠癌遗传与流行病学联盟、结直肠癌跨学科研究和结肠癌家族登记中的58221例患者和67694例对照组参与者数据。

研究结果显示:男性BMI每增加约4.2kg/m2,患结直肠癌的风险增加23%;在女性中,BMI每增加5.2kg/m2,患结肠癌的风险增加了9%。而腰臀比每增加0.07会使女性患癌症风险增加25%,而男性只增加了5%。

该研究结果表明,较高的BMI会显着增加男性的结直肠癌风险,而较高的腰臀围会显着增加女性的结直肠癌风险。肥胖与许多代谢变化有关,但这些还不能解释肥胖与结直肠癌之间的关系。需要更详细的代谢组学研究以阐明其机制。

根据世界卫生组织/国际癌症研究署发布的《2020全球癌症报告》显示,结直肠癌是全球第三大最常见的癌症,但它却是可以通过均衡饮食、增加运动和保持健康体重等方式的最可预防的癌症之一。

该研究通讯作者、布里斯托大学MRC综合流行病学系的Emma Vincent博士说:“我们这项研究是关于男性和女性体内脂肪和肠癌风险之间差异的最大型研究,强调了在预防癌症时需采取更为细致的方法。现在我们正努力研究,以确切理解身体脂肪增加是如何导致结直肠癌的,这可能会给我们带来降低癌症风险的新靶标。这很重要,因为维持体重对于很多人而言是非常困难的。”

世界癌症研究基金会(WCRF)的负责人Anna Diaz Font博士补充说:“我们知道,超重或肥胖会增加至少12种癌症的风险,包括结肠直肠癌。但这项新研究进一步强调了让更广泛的人群参与研究的重要性,因为我们还没能完全了解性别或种族在癌症风险方面可能发挥的作用。”

英国癌症研究中心的健康信息经理Natasha Paton解释说:“众所周知,不健康的体重会带来多种类型癌症的风险。但大多数关于肥胖与癌症的研究使用的指标都是BMI,但这项研究补充了腰部脂肪过多也有影响的新证据。人们可以通过保持健康体重、多吃纤维、少吃红肉和加工肉、少饮酒、不吸烟的方式来降低患结直肠癌的风险。另外,及早诊断肠癌也可以挽救生命。所以如果你发现任何异常变化,要及时就医。我们鼓励人们定期进行肠癌筛查。”
