title: [Health indicators associated with poor sleep quality among university students].
abstract: OBJECTIVE
  To associate the sleep quality of Brazilian undergraduate students with health indicators.
  
  
  METHODS
  A cross-sectional study was developed with a random sample of 662 undergraduate students from Fortaleza, Brazil. The demographic data, Pittsburgh Sleep Quality Index and health data indicators (smoking, alcoholism, sedentary lifestyle, nutritional condition and serum cholesterol) were collected through a self-administered questionnaire. Blood was collected at a clinical laboratory. In order to estimate the size of the associations, a Poisson Regression was used.
  
  
  RESULTS
  For students who are daily smokers, the occurrence of poor sleep was higher than in non-smokers (p<0.001). Prevalence rate values were nevertheless close to 1.
  
  
  CONCLUSIONS
  The likelihood of poor sleep is almost the same in smokers and in alcoholics.
