ABSTRACT
Objective To understand the quality of sleeping in medical students, and provide a reference basis for designing sleep health management program for college students. Methods The survey was conducted at a medical college in Shanxi province with stratified random sampling and Pittsburgh Sleep Quality Index (PSQI) scale. Totally 210 individuals were enrolled, 199 completed the questionnaire, with a response rate of 93.5%. SPSS 21.0 statistical software was used for data analysis. Descriptive statistical analysis was carried out for socio-demographic data. Independent t-test, one-way analysis of variance and non-parametric test were used to compare the scores of PSQI between participants. Multiple stepwise linear regression was used to determine influencing factors of sleep quality. Results The average score of PSQI for the 199 medical students interviewed was (6.74±2.42), the incidence of sleep disorder was 50.25%, the overall sleep quality was not high. Learning pressure of medical student had statistically significant in PSQI (Completely unmatched, 5.14 ± 2.32, Mostly unmatched, 5.93 ± 2.73, Mostly matched, 6.70 ± 2.42, Absolutely matched, 7.39 ± 2.10, F=3.366, P=0.020), employment pressure of medical students in PSQI (Completely unmatched, 6.50 ± 0.71, Mostly unmatched, 6.80 ± 3.24, Mostly matched, 5.98 ± 2.14, Absolutely matched, 7.14 ± 2.35, F=3.134, P=0.027). Grade (β=-0.172, P<0.05) and learning pressure (β=0.210, P<0.01) were the main influence factors for students. Conclusion Sleep quality of medical students was not high, upper grade was worse than low grade, the incidence of sleep disorder had increasing trend as learning pressure and degree of employment pressure worsen.
