Status of physical exercises during summer holidays and mental health and their correlations among medical students
Objective To investigate the status of physical exercises during summer holidays and mental health and their correla-tions among medical students,so as to provide insights into improvements in mental health among medical students.Methods A total of 1 121 medical students were sampled form a university using a random,stratified,cluster sampling method.Questionnaire surveys were performed using General Information Survey Forms,simplified Chinese version of Depression Anxiety Stress Scale-21(DASS21)and Physical Activity Rating Scale(PARS-3).Results A total of 1 121 subjects were enrolled,and the proportions of insufficient,moderate-intensity and high-intensity physical exercises were 76.4％,14.1％and 9.5％among participants,respectively.There were significant differences in the detection of insufficient physical exercises in terms of single child,gender,origin of students,monthly dis-posable money,family relations and self-rated physical status(x2=11.16to 89.21,all Pvalues＜0.05).The prevalence of depression,anxiety and stress was 25.0％,38.3％and 13.6％among participants,and there were significant differences in the detection of depres-sion,anxiety and stress in terms of family relations and self-rated physical status(x2=48.63 to 113.52,all Pvalues＜0.05).There was a grade-specific detection rate of depression among medical students(x2=8.93,P＜0.05),and PARS-3 scores negatively correlated with depression(rs=-0.16,P＜0.01),anxiety(rs=-0.12,P＜0.01)and stress scores(rs=-0.10,P＜0.01).Multivariate logistic re-gression analysis revealed that gender,physical exercise,family relations and self-rated physical status were significantly associated with depression and anxiety,and family relations and self-rated physical status were significantly associated with stress(OR=0.71 to 2.29,all P values＜0.05).Conclusions Insufficient physical exercises are common and the detection of depression,anxiety and stress is low among medical students during summer holidays.Active physical exercises may promote mental health.
