title: [Study on the relationship between college students' physical quality and the quality of sleep].
abstract: OBJECTIVE
  The author wants to investigate the relationship between college students' physical quality and the quality of sleep.
  
  
  METHODS
  Stratified cluster sampling method is used, and invites a total of 2981 Anhui college students to take part in the questionnaire study, the Pittsburgh sleep quality index (PSQI) and physical test, in order to survey the sleep quality and physical quality of college students. The physical quality and sleep quality are analyzed by the multiple factor non conditional logistic regression analysis methods.
  
  
  RESULTS
  PSQI scores of the 2744 students are (5.378 ± 2.492), 477 people (17.4%) have poor sleep quality. The endurance, speed, strength quality scores are (75.850 ± 13.279), (69.760 ± 16.422), (66.278 ± 18.709) points. Logistic regression analysis shows that excellent endurance (OR = 0.418) is a protective factor of sleep quality.
  
  
  CONCLUSIONS
  The improvement of endurance may improve sleep quality.
