title: Poor sleep quality of third-trimester pregnancy is a risk factor for postpartum depression.
abstract: BACKGROUND
  The aim of this study was to investigate whether poor sleep quality of third-trimester pregnancy is a risk factor for postpartum depression.
  
  
  METHODS
  Third-trimester pregnant women (T0, n=293) were tested using the first socio-demographic, Pittsburgh Sleep Quality Index, and Edinburgh Postnatal Depression Scale assessments, and received a diagnosis of depression. Three months (T1, n=223) after delivery, scale filling was finished and the structured interview was performed again.
  
  
  RESULTS
  We found that 73 persons (32.7%) were low income, 84 persons (37.7%) were middle-income, and 66 persons (29.6%) were higher income. The overall prevalence of postpartum depression was 9.4% (21 persons). After controlling for other factors, age, household income, marital satisfaction, and sleep quality were significantly related to postpartum depression, in which age and sleep quality scores (a higher score was associated with poorer sleep quality) were positively related to postpartum depression, and household income and marital satisfaction were negatively related to postpartum depression. Moreover, third-trimester sleep quality score was positively related to postpartum depressive symptoms.
  
  
  CONCLUSIONS
  Poor third-trimester subjective sleep quality is a risk factor for postpartum depression.
