ObjectiveTo study sleep quality and its related factors among middle school students in Changsha city,and to provide evidence for improving sleeping status of the students. MethodsTotally 2 216 middle school students in Changsha city were selected with cluster sampling and surveyed with questionnaires including a self-designed general questionnaire,Pittsburgh Sleep Quality Index(PSQI),Adolescent Self-Rating Life Events Check List (ASLEC) and Self-Esteem Scale(SES). ResultsThe overall prevalence of sleep problems was 14.4% in the students and the mean score of PSQI was 4.90±2.55. The sleep problems of the rural students and the senior high school students were worse than those in the urban students and the junior school students(P<0.01). The total score of PSQI was positively correlated with age,family violence,negative life event,and the score of self-esteem(r=0.051-0.316,P<0.05) and inversely correlated with familial economic status,family relationship and strict parents (r=-0.202-0.071,P<0.01).The factors influencing the quality of sleep in the students included negative life events(β=0.260),junior or senior student (β=0.166),family relationship(β=-0.128),the score of self-esteem(β=0.112),strict parents(β=-0.081),and familial economic status (β=0.081). ConclusionSleep quality of middle school students is related to multiple factors and effective measures should be taken to promote physical and mental health of middle school students.
