摘要
[目的]采用Meta分析法探讨吸烟与肝癌发病的相关性,为进行人群健康教育和预防决策提供依据。[方法]以肝癌组与对照组人群是否吸烟的OR值为效应指标,根据一致性检验的结果,选择随机效应模型对OR值进行合并并进行偏倚评估。采用GLS法检验吸烟量与OR值的剂量反应关系。[结果]共查到符合要求的国内外文献50篇,病例和对照数分别为10228、22312例。经异质性检验,50项研究结果存在异质性(q=267.75,P﹤0.0001),经过随机效应模型估计,以不吸烟人群为参比组,吸烟人群患肝癌的合并OR值为1.43(95%CI1.25~1.63)。按地域(亚洲、中北美洲、欧洲)合并OR值(95%CI)分别为1.46(1.24~1.72)、1.65(1.29~2.10)和1.14(0.83~1.57),按国别(国内、国外)合并OR值(95%CI)为1.32(1.07~1.63)和1.51(1.28~1.78),按对照选取的人群(正常人、非肝癌病人)合并OR值(95%CI)为1.41(1.21~1.64)和1.44(1.18~1.75),按研究设计的类型(病例对照、巢式病例对照)合并OR值(95%CI)为1.47(1.29~1.68)和1.00(0.54~1.82),OR值较一致。随吸烟量增加,肝癌发生风险在增加,呈现显著剂量反应关系(Z=4.76,P﹤0.0001)。[结论]吸烟是肝癌发病的危险因素。
