医学生负性生活事件与睡眠质量关系

目的 了解医学生睡眠质量的现况,探讨负性生活事件与睡眠质量之间的关系,为改善医学生睡眠质量提供依据。方法 采用青少年生活事件量表(ASLEC)和匹兹堡睡眠质量指数(PSQI)问卷对沈阳医学院预防医学专业学生进行现况调查。结果 364名医学生中20.6%存在睡眠问题,PSQI总分平均得分为(5.73±2.46)分。负性生活事件的发生率在36.81%～89.01%之间,ASLEC总分平均得分为(34.33±13.98)。ASLEC总分与PSQI 总分呈正相关(r=0.270,P<0.001)。ASLEC总分得分越高,PSQI得分可能越高(t=5.530,P<0.001)。结论 睡眠问题在医学生中有一定的发生率,负性生活事件得分越高睡眠质量越差呈正相关。

Relationship between negative life events and sleep quality among medical college students

Objective To examine the status of sleep quality and its association with negative life events among medical college students,and to provide evidences for improving sleeping quality of the students.Methods A self-administered questionnaire survey was conducted among 364 students selected from the Shenyang Medical College with stratified sampling.Adolescence Life Events Scale(ASLES)and Pittsburgh Sleep Quality Index(PSQI)questionnaire were used in the study.Results For all the students,20.6% had sleeping problems and the average PSQI score was 5.73 ± 2.46; the incidence of negative life events among the students ranged from 36.81%to 89.01% and the ALSEC score was 34.33± 13.98.The scores of ASLES and PSQI were positively correlated(r=0.270,P<0.001).Results of liner regression analysis showed that higher ASLES score predicted higher PSQI scores(t=5.530,P<0.001).The results of stepwise regression analysis showed that negative life events,such as study pressure,health adaptation,penalty factor,and other factors,could affect the quality of sleep(F=13.039,P=0.000).Conclusion There were a high prevalence of sleep disorders and a negative relationship between negative life events and the quality of sleep among the medical college students.
