[An investigation and analysis of abnormal menstruation in female nurses in a hospital in Beijing, China].

To investigate the status of abnormal menstruation in female nurses in a comprehensive hospital in Beijing, China and related influencing factors. In July 2016, a cross-sectional survey was performed, and a self-administered questionnaire was used to investigate the status of menstruation and occupation in female nurses in a comprehensive hospital in Beijing. The chi-square test and a multivariate logistic regression analysis were used for statistical analysis. A total of 892 female nurses were investigated, and among them, 485 experienced abnormal menstruation within the past three months, resulting in an abnormal menstruation rate of 54.37%. The female nurses who were exposed to harmful factors during work, negative life events, or high workload had a significantly higher abnormal menstruation rate than those who were not exposed to such factors (χ(2)=5.199, 16.186, and 10.227, <0.05 or <0.01) . Negative life events (odds ratio []=1.813, 95% confidence interval[]: 1.317-2.496) and high workload (=1.461, 95%: 1.112-1.918) were risk factors for abnormal menstruation. Nurses have an abnormal menstruation rate as high as 54.37%, and high workload and negative life events were risk factors for abnormal menstruation in nurses.
