abstract: OBJECTIVE
  To study the status and influencing factors on sleep quality in some medical college students.
  
  
  METHODS
  Stratified sampling, pittsburgh sleep quality index (PSQI), self-evaluation depression scale (SDS), self-evaluation anxiety scale (SAS) and self-developed questionnaire of influencing factors on the quality of sleep in medical college students were used. Cumulative odds logistic model was performed to analyze the related factors on the quality of sleep.
  
  
  RESULTS
  19.17 percent of the medical college students showed poor quality of sleep and the difference between genders was not statistically significant (P > 0.05). Statistically significant (P < 0.05) difference was seen among different years of students and correlation was found between sleep quality and depression or anxiety (P < 0.0001). Factors influencing on the quality of sleep in medical college students would include: worry of sleep, irregular work/rest, worry on examination, stress, relationship with classmates, self-evaluated health condition, environments of the dormitory and late to bed.
