To analyze the relationship between environmental lead exposure and various types of brain tumors.
Search databases PubMed, Web of Science, Embase and Chinese National Knowledge Infrastructure (CNKI) as of July 1, 2019. Stata 15.0 software was used for analysis.
In the case control, lead exposure was associated with gliomas and meningiomas 0.82 (95 % CI: 0.69, 0.95) and 1.06 (95 % CI: 0.65, 1.46). In the cohort study, lead exposure was associated with brain cancer and meningiomas 1.07 (95 % CI: 0.95, 1.19) and 1.06 (95 % CI: 0.94, 1.17). The risk of childhood brain tumors associated with parental lead exposure was 1.17 (95 % CI: 0.99, 1.34).
Lead may be a risk factor for meningiomas and brain cancers. However, the glioma results suggest that lead may be a protective factor, which needs to be further studied.
分析环境铅暴露与各种类型脑肿瘤之间的关系。
检索数据库 PubMed、Web of Science、Embase 和中国国家知识基础设施（CNKI），截至 2019 年 7 月 1 日。使用 Stata 15.0 软件进行分析。
在病例对照研究中，铅暴露与胶质瘤和脑膜瘤相关，比值比（OR）分别为 0.82（95%置信区间（CI）：0.69，0.95）和 1.06（95%CI：0.65，1.46）。在队列研究中，铅暴露与脑癌和脑膜瘤相关，OR 分别为 1.07（95%CI：0.95，1.19）和 1.06（95%CI：0.94，1.17）。父母铅暴露与儿童脑肿瘤的风险比（RR）为 1.17（95%CI：0.99，1.34）。
铅可能是脑膜瘤和脑癌的危险因素。然而，胶质瘤的结果表明，铅可能是一种保护因素，这需要进一步研究。
