Prevalence of job burnout and associated influencing factors among healthcare workers in China / 环境与职业医学

Background Healthcare workers suffer from great internal and external pressure and are prone to burnout. Existing studies have shown that depressive symptoms are important influencing factors of burnout, both of which are closely related to job stress. Objective To analyze overall prevalence of burnout among healthcare workers using a new survey tool developed by our team, and to reveal potential influencing factors related to burnout. Methods A cross-sectional multi-center study was conducted in August–October 2019 and June–September 2020, using multi-stage stratified cluster sampling. A total of 8738 healthcare workers from 22 hospitals in 5 provinces (Shandong, Hubei, Hunan, Guangdong, and Chongqing) of China were selected in this study. A set of survey questionnaires, including the general information questionnaire and the Chinese versions of General Burnout Scale, Core Occupational Stress Scale, Patient Health Questionnaire-9, and Self-administered Sleep Questionnaire were distributed. Independent samples t-test or one-way ANOVA were employed for inter-group comparison of burnout. Spearman correlation was used to evaluate correlations among burnout, depressive symptoms, and occupational stress. Stepwise linear regression was conducted to identify factors independently associated with burnout. Process plug-in was used to test potential mediating effect of depressive symptoms on occupational stress and burnout. Results Of the 8738 questionnaires distributed, 8456 valid questionnaires were collected, and the recovery rate was 96.77%. Among the 8456 healthcare workers, the prevalence of burnout was 58.0%, that of occupational stress was 31.8%, and that of depressive symptoms was 31.0%. Among those with depressive symptoms and occupational stress, the proportions of burnout were 86.7% and 83.7%, respectively. According to the stepwise linear regression analysis, depressive symptoms, occupational stress, work experience, drinking, and marital status were all independent influencing factors of burnout. Especially, depressive symptoms, social support, and organization and reward had significant influences on burnout (b'=0.455, −0.183, 0.220, P<0.001). Depressive symptoms showed mediating effects on occupational stress (and its subscales) and burnout, and the contribution rates of the mediating effects were 41.00%, 47.02%, 43.44%, 56.62%, and 59.45%, respectively. Conclusion Burnout is a prominent problem among healthcare workers in the 5 provinces, with the prevalence of 58.0%. And nearly 1/3 suffering from depressive symptoms and occupational stress, which has a great impact on burnout.

OBJECTIVE: To understand the research status on living conditions of patients with occupational pneumoconiosis in China. METHODS: The Chinese academic journal database, Wanfang Chinese periodical database and VIP database were used to search the relevant domestic literatures on the survival status of patients of occupational pneumoconiosis. The NoteExpress literature management software, VOSviewer 1.6.10 software and CiteSpace 5.2 software were used to sort out and visually analyze the searched literatures. RESULTS: A total of 4 043 articles were obtained, including 2 745 journal papers, 1 165 degree papers and 133 conference papers. The publication was increasing rapidly in years. The journal papers were published in 766 journals, and the degree papers came from 257 graduate training units. Disease prevention and control institutions, occupational defense institutions, colleges and universities were the supporting units of first authors that published the largest number of periodical papers. Pneumoconiosis was a high-frequency keyword. The emerging key words in this field from 2015 to 2019 include: occupational health examination, nursing intervention, lung function, industrial injury insurance, occupational health monitoring and quality of life. CONCLUSION: The number of literatures published on the survival status of pneumoconiosis patients in China shows a trend of rapid growth. The prominent words in the current and future studies on the living conditions of pneumoconiosis patients in China are occupational health examination, nursing intervention, lung function, industrial injury insurance, occupational health monitoring and quality of life.

Relationship between occupational stress and occupational musculoskeletal disorders in coal miners / 中国职业医学

OBJECTIVE: To explore the relationship between occupational stress and occupational musculoskeletal disorders( OMD) in coal miners. METHODS: A total of 362 coal miners were selected through cluster sampling method. The prevalence of OMD was investigated by the Nordic Standardized Questionnaires for Musculoskeletal Disorders( Chinese version). The Job Content Questionnaire and Effort Reward Imbalance Questionnaire were used to assess the occupational stress and depression of coal miners was determined by the Epidemiological Studies Depression Scale. RESULTS: The prevalence of OMD in coal miners was 63. 5%. There were 45. 9%( 166/362) of coal miners suffered from occupational stress with job demand-control model imbalance and 62. 4%( 226/362) of coal miners have occupational stress with effortreward model imbalance. The multiple logistic non-conditional regression analysis showed that the longer service length with exposure to occupational hazard factors,the more working days per week,the lower job contents and technical decisionmaking power,the higher the occupational stress with effort-reward imbalance,and the higher the depression and the higher the risk of OMD( P < 0. 05). CONCLUSION: Occupational stress and depression are both risk factors of OMD in coal miners.

The prevalence and influencing factors of work-related musculoskeletal disorders of oilfield workover workers / 中华劳动卫生职业病杂志

Objective@#To investigate work-related musculoskeletal disorders (WMSDs) of workover workers in an oilfield and explore the influencing factors.@*Methods@#In June 2016, 685 workover workers were selected as working group, and 191 other workers exposed to toxic and harmful operations were selected as control group. Cross sectional investigation was conducted by self-made questionnaire, and the influencing factors of musculoskeletal disorders were analyzed by unconditional multivariate Logistic regression.@*Results@#The total annual prevalence of WMSDs for workover workers was 90.5%, with the highest prevalence of low back pain of 71.5%. The prevalence of WMSDs increased with the increase of service age, and the difference between the drinkers was higher than that of the non drinkers (P<0.05) . Multivariate Logistic regression analysis showed that working age, drinking and the posture of lifting heavy objects were risk factors for WMSDs in workover workers.@*Conclusion@#The WMSDs appears to be a serious problem in oilfield workover workers. Corresponding measures should be taken to prevent the risk factors and control the occurrence of diseases effectively.

Relationship between quality of life and disability level in patients with occupational disease / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To investigate the relationship between the quality of life (QOL) and disability level in patients with occupational disease and to investigate the influencing factors for QOL.</p><p><b>METHODS</b>A total of 255 patients with occupational disease were selected from three specialized hospitals dedicated to occupational disease and the department of occupational medicine of one comprehensive hospital using cluster sampling from December 2013 to May 2014. A survey was carried out using WHOQOL-BREF and general questionnaire (including disability level), and statistical analysis was also performed using t test, F test, analysis of variance, and multivariate stepwise regression analysis.</p><p><b>RESULTS</b>The QOL scores of patients with occupational diseases, from high to low, were social domain (11.48 ± 2.86), psychological domain (10.60 ± 2.28), physiological domain (10.54 ± 1.65), and environmental domain (10.50 ± 2.55), scores of which were significantly lower than the normal levels (P<0.05). QOL showed no significant differences between patients with occupational diseases of different disability levels (P>0.05). Also, QOL showed no significant differences between stage I, II and III patients with pneumoconiosis (P>0.05). The patients with pneumoconiosis were divided into mild, moderate, and severe groups, and the QOL scores of patients with mild pneumoconiosis in psychological and environmental domains were significantly higher than those of the patients with moderate or severe pneumoconiosis (P< 0.05). Patients with occupational poisoning was divided into mild, moderate and severe groups, and the three groups showed no significant differences in QOL score (P>0.05). Multivariate regression analysis showed that the QOL score of each domain was mainly influenced by the degree of lung injury, complications, course of disease, age of onset, income, and employment status.</p><p><b>CONCLUSION</b>The QOL of patients with occupational disease is significantly reduced, and disability level cannot accurately reflect their QOL. The treatment of patients with occupational disease should focus on their complications, and at the same time QOL should also be improved.</p>

Relationship between occupational stress and depression in migrant workers / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To investigate the relationship between occupational stress and depression in migrant workers.</p><p><b>METHODS</b>Migrant workers in the textile industry were selected as subjects, and the self-made Occupational Stress Questionnaire and Self-rating Depression Scale were used to investigate the sex, age, seniority, educational level, and marital status of these subjects. Data analysis was performed by independent-samples t test, analysis of variance, Spearman rank correlation analysis, and stepwise multiple regression analysis.</p><p><b>RESULTS</b>Sex, seniority, and educational level were not influential factors for depression scores. The lower age group had a higher moderate depression score than the higher age group; the unmarried group had a higher moderate depression score than the married group. Severe depression was negatively correlated with decision-making power, psychological job demands, social support, and external pay-return, but positively correlated with skills and internal input; moderate depression was positively correlated with psychological job demands and external pay, but negatively correlated with other factors; mild depression was negatively correlated with all factors. The stepwise regression analysis showed that the influential factors for depression included, from major to minor, supervisor support, skills, internal input, and colleague support, according to the standardized regression coefficients; internal input was the contribution factor, and the remaining ones were negative factors.</p><p><b>CONCLUSION</b>Among migrant workers, certain mental health problems exist, and occupational stress is associated with depression.</p>
