Association between circadian rhythm disorder with depressive and anxiety symptoms of college students in Jinzhou City / 中国学校卫生

ABSTRACT

Objective@#To explore the association between circadian rhythm with depressive and anxiety symptoms of college students in Jinzhou City, to provide a theoretical basis for targeted depression and anxiety prevention among college students.@*Methods@#A total of 1 938 college students were selected by convenient sampling method from November to December 2020 for questionnaire survey. The relationship between circadian rhythm and depression and anxiety symptoms was analyzed by using questionnaire,survey including Self Rating Depression Scale (SDS), Self Rating Anxiety Scale (SAS) and Munich Chronotype Questionnaire (MCTQ).@*Results@#There were significant differences in the distribution of depressive symptoms in different majors, smoking, drinking and physical exercise ( χ 2=46.80, 5.88, 5.76, 12.23, P <0.05). There were significant differences in the distribution of anxiety symptoms in different majors, smoking and drinking ( χ 2=9.41, 5.80, 5.56, P <0.05). Stratified analysis showed that the depressive symptoms of different chronotype were statistically varied by age, gender, professional, grade, registered residence, body mass index, smoking, drinking, and sports( χ 2=8.16, 14.42, 12.25, 6.19, 10.99, 15.29, 17.41, 15.63, 7.47, 9.59, 10.51 , P <0.05). The anxiety symptoms of different chronotype were statistically different in age (21 years) and smoking (no), ( χ 2= 8.34 , 7.16, P <0.05). Spearman rank correlation showed that the corrected Mid sleep on Free Days Corrected for Sleep Debt on Work Days (MSFsc) was positively correlated with the standard scores of depression and anxiety ( r s=0.10, 0.09), and social jet lag was positively correlated with the standard scores of depression and anxiety ( r s=0.09, 0.05)( P <0.05). After controlling for age, major, smoking and drinking, binary Logistic regression showed that mean sleep length was inversely correlated with depressive symptoms ( OR =0.82), and weekly insomnia frequency was positively correlated with depressive symptoms ( OR=1.14 ).Early type and intermediate type of chronotypes were negatively correlated with depression ( OR =0.66,0.57). Intermediate type of chronotype was negatively correlated with anxiety symptoms ( OR =0.65).@*Conclusion@#Circadian rhythm is related to depressive and anxiety symptoms,among which the average sleep length, early rise and intermediate sleep patterns are negatively related to depression symptoms, and intermediate sleep patterns and anxiety symptoms, suggesting that circadian rhythm disorder may affect depression and anxiety symptoms.
