Abstract:

Objective   To investigate sleep quality among college students in order to develop preventive interventions. Methods   A retrospective study was conducted on the occurrence of injuries among 3 154 grade one and two students from a college in Huainan, Anhui. These students were selected by means of cluster sampling. The 260 students with recurrent injuries(i.e., ≥ 2 injuries per year) served as the experimental group, and a 1∶1 matched case-control study was performed. The Pittsburgh Sleep Quality Index (PSQI) questionnaire was used. Results   Incidence rate of injuries in college students was 27.65%, with fall injury being the highest(19.28%). Boys had higher incidences than girls(31.52%  vs 25.18%; P<0.01). There were significant differences between the experimental group and the control group, in the mean scores of subjective sleep quality, sleep time, sleep duration, sleep disorders and daytime dysfunction. A multivariate logistic regression analysis showed that sleep duration, sleep disorders and daytime dysfunction were the risk factors for injury. Students with abnormal sleep quality had an accident proneness, with OR being 1.91 times higher. Conclusion   Counter measures for injury prevention among students with recurrent injuries should be made according to their sleep quality.
