To explore the influencing factors of abnormal menstruation of female workers in a petrochemical enterprise. A total of 5186 female employees in a petrochemical enterprise were selected as the research objects from July 2018 to December 2019. A questionnaire survey was conducted from four aspects: basic information, occupational status, psychological status at work, reproductive and reproductive health, and a multivariate logistic regression model was used for analysis. Among 5132 female workers, 676 were postmenopausal and 1117 (25.1%) among 4456 non-postmenopausal women had abnormal menstruation in the last 6 months. Logistic regression analysis showed that age (<30、3035 years) and length of service (≤20 years) were protective factors (=0.573, 0.590, 0.798, <0.05) . Age (4045、45~50 years old) , sleep duration (<6 h) , premature OR late menopause of maternal relatives, occupational exposure to dust, occupational exposure to chemicals, not wearing earplugs, leave due to health reasons in the last 6 months, reproductive tract infection OR symptoms in the last 6 months, spontaneous abortion, induced abortion, physical fatigue and mental fatigue were risk factors for menstrual abnormalities in female workers (=2.318, 5.544, 1.231, 1.199, 1.336, 1.403, 1.351, 1.538, 1.613, 1.584, 1.199, 1.601, 1.936, <0.05) . The abnormal menstruation of female workers is affected by many factors in the occupational process, and specific measures should be taken to improve the reproductive health of female workers.
