Abstract

目的 定量分析人造矿物纤维(man-made mineral fiber,MMMF)与呼吸系统肿瘤的关系.方法 应用Meta分析方法对MMMF与呼吸系统肿瘤的病例对照研究进行分析.统计学处理采用固定效应模型,用Q统计量进行异质性检验,用Begg's法检验发表性偏倚,并进行敏感性分析.结果 共纳入11个病例对照研究12篇文献,发表时间为1986至2008年,研究地区包括丹麦、挪威、瑞典、德国、英国、捷克、匈牙利、波兰、罗马尼亚、俄罗斯、斯洛文尼亚、加拿大和美国.未校正混杂因素的合并OR粗=1.146(0.598~2.195),校正混杂因素后的OR_(校正)=1.30(0.75-2.24),单纯接触玻璃纤维的合并OR=1.23(0.16-9.35),单纯接触矿物棉的合并OR=1.43(0.57~3.58).结论 尚不能认为MMMF可致呼吸系统肿瘤发病风险升高,在今后的研究中需控制无差异性错误分类、混杂偏倚等的影响。
