Female students (19.2%) were more susceptible topoor sleep quality (χ~2=4.847，P=0.028)than male students(15.9%). Additionally, students withanxiety or depressive symptoms were more likely to have poor sleep quality compared with thosewithout such symptoms. Results of multiple logistic regression analysis indicated that female，anxiety and depressive symptoms were associated with increased risk of poor sleep quality(OR=1.262，95%CI:1.019-1.562; OR=2.691,95%CI:2.151-3.368; OR=2.955,95%CI:2.386-3.659respectively).Conclusion The sleep quality of higher vocational college students is not optimistic and even moreserious for Female students.Bad mood is a risk factor for sleep quality problem.
