Br J Cancer:多运动,可降低结直肠癌患病风险

结直肠癌是发达社会中最常见的癌症之一。既往研究显示,肥胖是结直肠癌发病的危险因素之一。高热量饮食并久坐不动的生活方式使得肥胖已成为发达国家的一大公共卫生问题,这也进一步的加剧了结直肠癌的发病率。

观察性流行病学研究相关证据显示,体育活动(PA)的增加对应着结直肠癌患病风险的降低。且有充分的证据表明,娱乐性PA与结直肠癌之间存在保护性关联。荟萃分析显示,职业性活动、娱乐性活动、运输相关的PA和职业性久坐行为的减少均与较低的结直肠癌患病风险相关。


尽管目前关于PA对结直肠癌患病风险的影响已有有力的相关证据,但由于混杂因素或残余混杂的影响,相关的观察性研究仍不能归因于此。此外,在观察研究中,PA通常作为一种自我报告的活动形式进行测量。

在该研究中,研究人员通过孟德尔随机(MR)研究,旨在调查PA是否会降低结直肠癌的患病风险,并探究体内脂肪变化在其中的贡献。


自我报告的中重度PA(MVPA),加速度矢量幅度PA(AMPA)和久坐时间相关的常见遗传变异在该研究中被用作为工具变量。为了控制肥胖症的混杂影响,研究人员纳入了体重指数(BMI)、体脂百分比、腰围和手臂、躯干和腿部的脂肪比率的相关工具变量。通过MR研究设计,分析这些工具变量在结直肠癌全基因组关联研究中的作用,该研究共包括31,197例病例和61,770例对照。

结果显示,通过遗传学方法测量,MVPA和AMPA降低了结直肠癌的患病风险,这是通过肥胖症的遗传学测量所介导的。MVPA和AMPA每标准差增加的优势比和95%置信区间(CI)分别为0.56(0.31,1.01)和0.60(0.41,0.88)。


进一步的研究显示,久坐时间和结直肠癌的患病风险之间并无关联性。对于MVPA和AMPA,BMI介导的作用比例分别为2%(95%CI:0,14)和32%(95%CI:12,46)。

BMI和身体脂肪组成的比例评估

总而言之,该研究结果为加强预防结直肠癌的公共卫生措施提供了有力的证据,研究人员建议,无论身体脂肪状态如何,促进人群PA的发展或对于降低结直肠癌患病风险有益。
