Abstract

随着公众健康意识的提升,探索经济有效的癌症预防策略至关重要。据推测,规律运动可通过抑制全身慢性炎症降低肿瘤风险。C反应蛋白(C reactive protein, CRP)作为常用炎症标志物,运动可以降低全身CRP水平。但“运动-炎症-癌症”三者之间的关系的内在机制及作用途径仍有待深入研究。本文旨在探究中国人群中运动与癌症发生和死亡风险之间的关系及其可能作用途径,为此整合中国嘉道理生物样本库(China Kadoorie Biobank, CKB)和上海浦东前瞻性队列(后文简称“上海队列”)数据,共纳入522,165名研究对象,分析人口学特征、运动史、CRP、高敏C反应蛋白(high-sensitivity C-reactive protein, hs-CRP)与癌症结局,根据CRP/hs-CRP水平中位数,将研究对象分为高/低炎症状态组,健康人群定义为基线无慢性病者。两队列全人群及健康人群中运动组的CRP/hs-CRP均低于非运动组(P<0.05),提示运动与体内低炎症水平显著相关。高炎症水平显著增加癌症发病风险(上海队列:风险比[hazard ratio, HR]=1.252, 95%置信区间[confidence interval, CI]: 1.031–1.520;CKB队列: HR=1.351, 95% CI: 1.172–1.558)与死亡风险(上海队列: HR=1.491, 95% CI: 1.179–1.886;CKB队列: HR=1.428, 95% CI: 1.203–1.696)。限制性立方样条(Restricted Cubic Spline, RCS)分析表明CRP/hs-CRP与癌症风险呈显著非线性正相关(P<0.05),CKB队列中,当hs-CRP>1 mg/L时癌症风险随浓度递增。运动显著降低两队列低炎症人群癌症死亡风险(CKB: HR=0.73, P<0.05; 上海队列: HR=0.57, P<0.001);CKB队列中慢跑人群的癌症发生与死亡率低于其他运动类型(P<0.05)。综上,运动可能通过抑制炎症通路降低癌症发生与死亡,推广以慢跑为主的运动方式对癌症一级预防具重要公共卫生意义。
