Abstract：Objective To study the difference between Chinese medical and non-medical college students in sleep disorder. Methods The articles about sleep disorder surveyed by Pittsburgh sleep quality index (PSQI) between 2005 and 2019 were screened and analyzed by meta-analysis (Stata/SE 12.0 and R3.6.1). The published bias was detected by Egger's test and Begg's test. Results Ten articles were selected for meta-analysis. The sleep disorder rate was 29.64% (95%CI: 22.51%-37.30%) of 3 670 medical students and 22.51% (95%CI: 15.90%-29.88%) of 6 514 non-medical students. The meta-analysis showed that the rate of sleep disorder of medical students was significantly higher than that of non-medical students (RR=1.30, 95%CI: 1.08-1.57, P=0.005). Egger's test (t=-0.31, P=0.766) and Begg's test (z=1.43, P=0.152) indicated that there was no significant bias. Conclusion The sleep disorder rate of the medical students is significantly higher than that of the non-medical students.
