摘要(Abstract):
目的探究大蒜摄入与人群结直肠癌(colorectal/colon/rectal cancer,CRC)发病风险之间的关系。方法检索数据库PubMed、Web of Science、Embase和CNKI,搜索大蒜摄入与CRC发病风险相关的队列研究和病例对照研究。通过纳入与排除标准筛选符合要求的文献,然后提取相关数据,在Stata软件中进行meta分析,探究大蒜摄入与CRC发病风险之间的关系。结果本研究共纳入研究14篇,包括7项队列研究和7项病例对照研究。分析结果显示,大蒜低、中等及高摄入组合并效应量ES及95%置信区间(confidence interval,CI)分别为0.82(95%CI:0.7730.867),0.625(95%CI:0.5940.867),0.625(95%CI:0.5940.655)及0.321(95%CI:0.2970.655)及0.321(95%CI:0.2970.345)(P<0.05),女性组合并效应量ES=1.188(95%CI:1.090.345)(P<0.05),女性组合并效应量ES=1.188(95%CI:1.091.286)(P<0.05)。结论大蒜摄入可以明显降低CRC患病风险。而在相同修正因素下,男性患CRC风险的降低较女性显著。
