title: Sleep disturbance and correlates in menopausal women in Shanghai.
abstract: OBJECTIVE
  The aim of this study was to investigate the sleep disturbance and its correlates in Chinese middle-aged women.
  
  
  METHODS
  A total of 2046 Chinese women 40-60 years of age were recruited in this cross-sectional descriptive study. The subjects were surveyed using the Pittsburgh Sleep Quality Index (PSQI), the modified Kupperman Index (KI), and a general questionnaire to obtain sociodemographic data. Data were analyzed using SPSS 20.0 software.
  
  
  RESULTS
  In this study, the mean (standard deviation) age of the participants was 51.69 (6.54) years and the mean PSQI score was 6.88 (3.20). The prevalence of sleep disturbance was 33.2% (a PSQI global score ≥8). The prevalence of sleep disturbance was higher in women with a menopausal status (from 34.8% in premenopausal women to 40.9% in postmenopausal women, P < .001) and in women with an increased age (from 21.7% in women 40-44 years of age to 41.8% in women 55-60 years of age, P < .001). Vasomotor symptoms (classical menopausal symptoms, VMS) were associated with sleep disturbance. An increase in the severity of menopausal symptoms (higher total KI scores) was observed in women who experienced sleep disturbance. A logistic regression analysis revealed that menopausal status, vasomotor symptoms, modified KI scores, a history of disease, and older age (≥ 50 years) were significant risk factors for sleep disturbance.
  
  
  CONCLUSIONS
  Sleep disturbance was highly prevalent in this large sample of middle-aged Chinese women. Therefore, clinicians should pay more attention to sleep problems in middle-aged Chinese women and measures should be taken to improve the quality of sleep in these women.
