为了解不同行业女职工倒班工作分布情况以及倒班工作与生殖健康的关系，为女职工劳动保护提供参考依据。于2016年6月至9月，对电子、医药卫生、制药等11个行业的女职工进行整群抽样问卷调查，了解这些女职工的一般情况、倒班工作情况、生殖健康及生育史等。共收集有效问卷63 711份，有效回收率为96.94%。共有13 546名职工倒班，占21.26%，其中医疗行业倒班比例最高，为30.61%，冶金行业为30.81%，石油化工行业为26.78%。与不倒班职工相比，倒班职工月经异常率、已婚职工生殖系统感染率、不孕率均显著升高（χ²=19.108、10.673、21.510，P<0.05）；与不上夜班职工相比，上夜班职工月经异常率、已婚职工生殖系统感染率、不孕率均显著升高（χ²=140.043、71.901、29.024，P<0.01）。倒班工作比例最高的行业为医疗行业、冶金行业、石油化工行业。倒班职工存在较严重的生殖健康问题，月经异常、生殖系统感染及不孕的发生可能与倒班工作有关。
