ABSTRACT
OBJECTIVE: To investigate the sleep quality and influencing factors of perimenopausal women in Ningbo region. METHODS: A total of 527 perimenopausal women who lived in Ningbo for more than 5 years were enrolled in the study. The subjects were surveyed by self-designed questionnaire and Pittsburgh sleep quality index (PSQI); PSQI > 7 was defined as the cut-off value for sleep quality. Data were analyzed by software SPSS 11.0. RESULT: The mean PSQI score was 5.79 ± 3.08 and 23.6 % of perimenopausal women in the study showed poor sleep quality. The proportion of poor sleep in 55-60 age group was 40.2%, significantly higher than that of 40-44, 45-49 and 50-54 age groups (P < 0.05). The sleep quality was associated with physical exercise, social activity, sleep circumstance, anxiety and family income in perimenopausal women. CONCLUSION: The sleep quality of perimenopausal women and the influencing factors are associated with mental health, life style and social environment, which suggests that some interventions should be undertaken to improve the sleep quality of perimenopausal women.
