Women's employment in Japan has increased substantially in recent decades, however little large scale research has been done on the impact of various types of working conditions on women's health. The aim of this study was to assess the menstrual cycle and menstrual pain problems of female workers and to investigate the factors that relate to them. The questionnaire was distributed to 8,150 women and 2,166 responded (26.6%). An anonymous self-administered questionnaire was used to get information about demographics, menstrual cycle status, the degree of menstrual pain, and employment and environmental factors. Irregular cycle menstruation was experienced in 17.1% of responded workers. We discovered the relationship between irregular menstrual cycles and stress, smell of cigarettes, age and smoking habits. Some degree of menstrual pain was experienced in 77.6% of responded workers. This study showed the relationship between menstrual pain and stress, high temperature and humidity, age, BMI, and number of births. In conclusion, we found that stress is thought to be an important factor related with menstrual cycle irregularities and menstrual pain among Japanese female workers.
近几十年来，日本女性的就业人数大幅增加，但针对各种工作条件对女性健康的影响，几乎没有进行大规模的研究。本研究旨在评估女性工人的月经周期和月经痛问题，并调查与之相关的因素。该问卷分发给了 8150 名女性，其中 2166 名（26.6%）做出了回应。我们使用匿名的自我管理问卷来获取有关人口统计学、月经周期状况、月经痛程度以及工作和环境因素的信息。在做出回应的工人中，有 17.1%的人经历了不规律的月经周期。我们发现不规则的月经周期与压力、香烟气味、年龄和吸烟习惯有关。在做出回应的工人中，有 77.6%的人经历了某种程度的月经痛。这项研究表明，月经痛与压力、高温高湿度、年龄、BMI 和生育次数有关。总之，我们发现，在日本女性工人中，压力被认为是与月经周期不规律和月经痛有关的重要因素。
