In this study, the characteristics of menstrual cycle in shift workers employed in the pharmaceutical industry are investigated.
This study was conducted in a pharmaceutical industrial complex in Tehran in 2012. 406 female workers in packaging units were studied on the menstrual cycle characteristics. The studied workers were divided into two groups of shift workers and non-shift workers and were compared in terms of the frequency of menstrual disorder (short-term cycle, long-term cycle, irregular cycle and bleeding during menstrual cycle) as well as hormonal values (FSH, LH, TSH, and Prolactin).
The odds ratio (OR) for menstrual disorder in the shift workers was 5.54 (95% CI=2.78-11.02) compared to the non-shift workers. The mean difference of hormonal values (except prolactin) between shift workers and non-shift workers was not significant (P>0.05).
This study suggests that shift work may disrupt the menstrual cycle.
本研究调查了制药行业倒班工人的月经周期特征。
2012年在德黑兰的一个制药工业园区开展了本研究。对包装部门的406名女工的月经周期特征进行了研究。将研究对象分为倒班工人和非倒班工人两组，并就月经紊乱频率（短周期、长周期、不规则周期和经期出血）以及激素值（促卵泡生成素、促黄体生成素、促甲状腺激素和催乳素）进行了比较。
与非倒班工人相比，倒班工人月经紊乱的优势比（OR）为5.54（95%置信区间=2.78-11.02）。倒班工人和非倒班工人之间激素值（催乳素除外）的平均差异不显著（P>0.05）。
本研究表明倒班工作可能会扰乱月经周期。
