title: [Traditional Chinese medicine constitution types in 127 elderly patients with insomnia: an investigation in communities of Yangpu District, Shanghai].
abstract: OBJECTIVE
  To analyze the distribution of traditional Chinese medicine constitution types in elderly patients with insomnia.
  
  
  METHODS
  The epidemiological data were collected from communities in the Yangpu District, Shanghai via a cross-sectional field survey. The elderly participants were enrolled by using the Pittsburgh Sleep Quality Index (PSQI) scale and the TCM Constitution Questionnaire.
  
  
  RESULTS
  (1)The distribution of imbalanced constitutions between the elderly with insomnia and normal subjects showed statistical difference (P<0.01) and the elderly with insomnia tend to be of imbalanced constitutions. Among these unbalanced constitutions, deficient constitutions were more frequent than others in the elderly with insomnia, and yang-deficiency and qi-deficiency occurred mostly in unbalanced and simple constitutions. (2) Blood-stasis and qi-stagnation constitutions were more frequent in females than in males among the elderly with insomnia. Frequency of deficiency constitutions in the elderly increased as the age increases. (3) The frequency of composite constitutions was higher than that of simple constitutions in elderly patients with insomnia (74.8%), among which qi-deficiency was more likely to be composite with other constitutions.
  
  
  CONCLUSIONS
  Identification and classification of traditional Chinese medicine constitution types will provide further information for devising projects with systematic intervention for insomnia management.
