长工时作业和通勤时间对中国女护士月经异常的影响

Study on the effects of long working hours and commuting time on menstrual abnormalities among Chinese female nurses

目的评价长工时作业和通勤时间对女护士月经状况的影响,为相关部门合理调配护士的工作时间提供依据。方法2016年5月―2016年11月对中国8904名女护士进行问卷调查,收集人口学、职业和月经状况数据,用二分类logistic回归分析模型分析长工时作业与通勤时间对月经异常的影响。结果女护士工作时间为(8.2±1.1)h、中位通勤时间为1.0(0.5,1.0)h。月经异常率为41.0%。工作时间>8 h对女护士的月经异常各指标均有影响,其中对月经持续时间变化的影响最大(OR=1.651,95%CI:1.403~1.942,P<0.001)。通勤时间>1 h对月经异常各指标均有影响,其中对月经持续时间变化的影响最大(OR=1.368,95%CI:1.178~1.588,P<0.001)。结论长工时作业与通勤时间较长会导致女护士月经异常风险升高,是月经异常的影响因素。

Objective To evaluate the effects of long-time work and commuting time on the menstrual status of female nurses, and to provide a basis for relevant departments to reasonably allocate the working hours of nurses. Methods A questionnaire survey was conducted among 8 904 female nurses in China from May to November 2016. Demographic, occupational and menstrual data were collected. The effects of long-time work and commuting time on menstrual abnormalities were analyzed by binary logistic regression models. Results The working time of female nurses was(8.2±1.1) h, and the median commuting time was 1.0(0.5, 1.0) h;The abnormal rate of menstruation was 41.0%. Working time > 8 h had a significant impact on all indexes of menstrual abnormalities of female nurses, and had the greatest impact on the change of menstrual duration(OR=1.651, 95% CI: 1.403-1.942, P<0.001). Commuting time > 1 h had a significant impact on all indicators of menstrual abnormalities, among which it had the greatest impact on the change of menstrual duration(OR=1.368, 95% CI: 1.178-1.588, P<0.001). Conclusion Long working hours and long commuting time increase the risk of abnormal menstruation in female nurses, and it is the influencing factor of abnormal menstruation.
