Objective To investigate the
sleep quality of
students from a medical
university and to analyze the
risk factors of
sleep disorders.
Methods Students from a medical
university were selected with
cluster sampling method. A total of 886
students were included in this study there were 55 Major A
students, 80 Major B
students, 97 Major C
students, 577 Major D
students, and 77 Major E
students. The
students were investigated by Pittsburgh
sleep quality index (PSQI) and sel-designed physical
state questionnaire. Results (1)The number of effective
questionnaire was 843 and
sleep disorders were found in 284
students, with an
incidence of 33. 7% and a PSQI score of 5. 48 + 0. 12. The
incidences of
sleep orders and PSQI scores were 43. 4% (23/53) and 6. 23 + 0. 48 for Major A, 32. 9% (23/70) and 4. 93 + 0. 44 for Major B, 40. 4% (36/89) and 5. 75 + 0. 34 for Major C, 32. 4% (183/564) and 5. 47 + 0. 14 for Major D and 28. 4% (19/67) and 5. 18 + 0. 40 for Major E, with no significant difference found for different majors (P>0. 05). (2)The factors leading to somnipathy included
emotional stress, ambient
noise,
somatic pain,
school learning, seldom late-night
snack and occasional late-night
snack (OR=0. 577, 0. 611, 0. 265, 0. 260, 0. 547, and 0. 507, respectively). Conclusion The
students in the involved medical
university have a low
sleep quality which may
affect their physical
state during day
time. Active
measures should be taken to improve
students sleep quality so as to insure their study.
