睡眠质量在宁夏职业人群倦怠与抑郁情绪间的中介作用
Mediating role of sleep quality between job burnout and depressive symptoms among Ningxia occupational population
摘要
Abstract
[Background]Job burnout and depressive symptoms are prevalent among occupational popula-tions,with a close relationship between them.Sleep quality,as a potential mediating factor,sig-nificantly affects the mental health of workers. [Objective]To explore the relationship between job burnout,sleep quality,and depressive symptoms,and determine whether sleep quality mediates the relationship between job burnout and depressive symptoms. [Methods]From April 25 to May 1,2024,this study employed cluster sampling to conduct a questionnaire survey among individuals en-gaged in various occupations across five cities in the Ningxia Hui Autonomous Region.The questionnaires included socio-demographic in-formation,as well as the Chinese Maslach Burnout Inventory(CMBI),the Pittsburgh Sleep Quality Index(PSQI),and the Patient Health Questionnaire-9(PHQ-9)for assessing burnout,sleep quality,and depressive symptoms,respectively.Out of the 4106 questionnaires distributed,a total of 3 837 questionnaires were valid,and the valid recovery rate was 93.45％.The distribution among demographic vari-ables in burnout,sleep quality and depressive symptoms were statistically analyzed.A binary logistic regression model was used for mul-tifactor correlation analysis;Pearson correlation was used to test the correlation between burnout,sleep quality,and depressed mood.Modelling and mediated effect path mapping were performed using Amos 24.0 software. [Results]The postive rate of occupational burnout in the workers was 97.49％(3 741/3 837),the positive rate of poor sleep quality was 66.77％(2526/3837),and the positive rate of depressive symptoms was 75.68％(2 904/3837).There were statistically significant differ-ences in depressive symptoms by ages,shift types,working years,marital status,smoking habits,drinking habits,and exercising frequency(P＜0.05).The logistic model indicated that working years,drinking habits,job burnout,and overall sleep quality were significant factors influencing the occurrence of depressive symptoms(P＜0.05).The correlation analysis revealed positive correlations between depressive symptom scores and job burnout scores(r=0.045,P＜0.01),between depressive symptom scores and sleep quality scores(r=0.480,P＜0.01),and between job burnout scores and sleep quality scores(r=0.054,P＜0.01).Furthermore,the indirect effect of job burnout on depressive symptoms through sleep quality was 0.100(95％CI:0.204,0.252;P＜0.01). [Conclusion]Job burnout and sleep quality are significant factors associated with the occurrence of depressive symptoms among occu-pational populations,and sleep quality plays a partial mediating role in depressive symptoms associated with job burnout.This finding may provide a scientific basis for developing intervention strategies to control depressive symptoms among workers.关键词
