ABSTRACT
Objective: To explore the relationship between shift work and menopausal age and menstruation span of retired women. Methods: During July 2017 and October 2018, the research was performed by using cluster sampling in nine districts of Shenzhen City to select all permanent residents (3518 people) with Shenzhen household registration in which was equal to or over 60 years old from the Community Health Service Centers. The data of age, marital status, menopausal age, smoking, drinking, shift experience and shift years were collected. The relationship between shift work and menopausal age as well as menstruation span of professional women were analyzed by multivariate linear regression model. Results: There were 359 people (10.2%) in the shift experience group, the menopausal age was (49.71±3.63) years, and the menstrual period was (34.27±3.92) years. The non-shift experience group were 3159 people (89.8%) , the menopausal age was (50.20±3.60) years, and the menstrual period was (34.86±4.13) years. The differences of menopausal age and menstrual years between the two groups were statistically significant (P<0.05) . After adjusting for factors such as passive smoking and drinking, the results of the multiple linear regression model showed that menopausal age, menstrual years were negatively correlated with shift work (β=-0.493, -0.575, P<0.05) . Conclusion: Shifts are related to women’s menopausal age and menstrual years, and attention should be paid to the impact of work intensity and circadian rhythm on the occupational health of female employees.
