目的:探讨男性电磁辐射职业暴露与其子代性别比之间的关系。方法:检索国内外各类大型数据库发表的有关男性电磁辐射职业暴露与其子代性别比关系的文献,采用Meta分析的方法,通过Stata 11.0软件评价二者之间的关系。结果:Meta分析结果表明暴露于职业环境电磁辐射的男性其子代性别比与非暴露于电磁辐射者子代性别比没有统计学差异,OR值为1.00(95%CI:0.95～1.05),P=0.875。按照研究类型分层分析,病例对照组和队列组是否暴露于职业环境电磁辐射的男性的子代性别比均无统计学差异,OR值分别为:1.03(95%CI:0.99～1.08),P=0.104;0.98(95%CI:0.99～1.08),P=0.186。结论:男性有无电磁辐射的职业暴露与其子代性别比之间未发现明显相关。
Objective: To explore the relationship between occupational exposure to male electromagnetic radiation and sex ratio of offspring. Methods: The literature about the relationship between occupational exposure to male electromagnetic radiation and the sex ratio of their offspring published in various large databases at home and abroad was searched. The relationship between the two was evaluated by the method of Meta analysis and Stata 11.0 software. Results: The results of Meta-analysis showed that there was no significant difference in sex ratio between offspring and non-exposed to electromagnetic radiation among men who exposed to electromagnetic radiation in occupational environment. The odds ratio was 1.00 (95% CI: 0.95-1.05), P = 0.875. According to the study type, the sex ratio of offspring of men in case control group and cohort group exposed to electromagnetic radiation in occupational environment had no statistical difference. The OR values were 1.03 (95% CI: 0.99-1.08), P = 0.104; 0.98 (95% CI: 0.99-1.08), P = 0.186. Conclusion: There is no significant correlation between male occupational exposure to electromagnetic radiation and sex ratio of offspring.
