Factors associated with menopausal symptoms among middle-aged registered nurses in Beijing

Objective: To determine factors related to menopause symptoms among middle-aged registered nurses in Beijing. Methods: Self-administered questionnaires that included closed-ended questions on many factors possibly related to menopausal symptoms were distributed to 2100 registered nurses aged 40-55 at 20 hospitals in Beijing, China. Results: Menopausal status was most associated with menopausal symptoms (p < 0.01), including hot flashes and sweating, paresthesiae, insomnia, arthralgia/myalgia, palpitations, skin formication and an unsatisfactory sexual life. The odds ratios (ORs) were highest for hot flashes and sweating. Upsetting events in the past year and being pessimistic were significantly inversely correlated with almost all the symptoms analyzed. Hot flashes and sweating (p < 0.01), paresthesiae (p < 0.01), unsatisfactory sexual life (p < 0.01), irritability (p < 0.05), depression or suspicion (p < 0.05) and dizziness (p < 0.05) were negatively correlated with the frequency of sexual activity. Conclusion: Many factors may influence symptoms of the menopause. We found that menopausal status was most strongly associated with most menopausal symptoms, especially hot flashes and sweating. Psychosocial factors also played an important role. A higher frequency of sexual activity negatively correlated with most menopausal symptoms.
