Rotating shift work can cause abnormalities in their endocrine system. We conducted a meta-analysis to gain a better understanding of the differences between women working rotating shifts and fixed day shifts in menstrual regularity and dysmenorrhea. We searched for studies containing relevant keywords that were published between 1990 and 2019 in the Cochrane Library, EBSCO (including the Cumulative Index to Nursing and Allied Health Literature [CINAHL]), MEDLINE, and ProQuest. Data analysis was performed using the software package Comprehensive Meta-Analysis (CMA) Version 3.0. A total of 14 studies met our selection criteria. The pooled odds ratio (OR) comparing the menstrual irregularity of women working rotating shifts and fixed day shifts was 1.35 (95% confidence interval [CI]: 1.28-1.42, < 0.001). The pooled OR of the women aged 30 years or older was 1.35 (95% CI: 1.28-1.42, < 0.001); and for the women under 30 years old, the pooled OR was 1.66 (95% CI: 1.13-2.44, = 0.010). The pooled OR comparing the dysmenorrhea occurrence among women working rotating shifts and fixed day shifts was 1.51 (95% CI: 0.87-2.62, = 0.139). The pooled OR of the women aged 30 years or older was 2.35 (95% CI: 1.63-3.39, < 0.001); and for the women under 30 years old, the pooled OR was 1.20 (95% CI: 0.61-2.33, = 0.601). The results indicate that regardless of age, women working rotating shifts were more likely to experience menstrual irregularity than those working fixed day shifts. With regard to dysmenorrhea, among women aged 30 years or older, those working rotating shifts were also more likely to experience dysmenorrhea than those working fixed day shifts.
轮班工作可能导致其内分泌系统出现异常。我们进行了一项荟萃分析，以更好地了解从事轮班工作的女性与从事固定日班工作的女性在月经规律和痛经方面的差异。我们检索了 1990 年至 2019 年期间在 Cochrane 图书馆、EBSCO（包括 Cumulative Index to Nursing and Allied Health Literature [CINAHL]）、MEDLINE 和 ProQuest 中含有相关关键词的研究。数据分析使用 Comprehensive Meta-Analysis（CMA）Version 3.0 软件包进行。共有 14 项研究符合我们的选择标准。比较从事轮班工作和固定日班工作的女性月经不规律的合并优势比（OR）为 1.35（95%置信区间 [CI]：1.28-1.42，<0.001）。年龄在 30 岁或以上的女性的合并 OR 为 1.35（95% CI：1.28-1.42，<0.001）；年龄在 30 岁以下的女性的合并 OR 为 1.66（95% CI：1.13-2.44，=0.010）。比较从事轮班工作和固定日班工作的女性痛经发生率的合并 OR 为 1.51（95% CI：0.87-2.62，=0.139）。年龄在 30 岁或以上的女性的合并 OR 为 2.35（95% CI：1.63-3.39，<0.001）；年龄在 30 岁以下的女性的合并 OR 为 1.20（95% CI：0.61-2.33，=0.601）。结果表明，无论年龄大小，从事轮班工作的女性月经不规律的可能性都高于从事固定日班工作的女性。至于痛经，在 30 岁或以上的女性中，从事轮班工作的女性也比从事固定日班工作的女性更容易出现痛经。
