Current situation and related factors of occupational stress of employees of a petrochemical enterprise / 环境与职业医学

Background Occupational stress has become one of the main factors affecting people's physical and mental health, and there are many sources of occupational stress in petrochemical enterprises. Objective To evaluate the current situation of occupational stress and its related factors among employees in a petrochemical enterprise, and to provide a scientific basis for reduing the risk of occupational stress among employees in petrochemical enterprises. Methods In June 2022, a cross-sectional questionnaire survey was conducted in a petrochemical enterprise in Hainan, including a general information questionnaire for basic information, the Effort-Reward Imbalance (ERI) for occupational stress, and the Pittsburgh Sleep Quality Index (PSQI) for sleep quality. Chi-square test was used to compare differences in positive occupational stress by demographic characteristics, occupational characteristics, behavior, and occupational disease hazards. Logistic regression was employed to evaluate factors associated with occupational stress. Results Of the 1129 questionnaire distributed, a total of 999 valid questionnaire were returned,with a valid recovery rate of 88.5%. The positive rate of occupational stress among employees in the petrochemical enterprise was 29.5%. There were statistically significant differences in the positive rate of occupational stress among the employees grouped by gender, age, marital status, body mass index (BMI), monthly income, length of service, smoking, weekly working hours, type of work, working mode, sleep quality, noise exposure, and high temperature exposure (P<0.05). In terms of positive occupational stress among subcategories: workers being male (vs. female), working ＞40 h per week (vs. ≤40 h per week), regular day shift (vs. shift work), smoking (vs. not smoking), with exposure to noise and heat (vs. without such exposure), and having poor sleep quality (vs. good sleep quality) reported higher positive occupational stress rates (P＜0.05). The results of pairwise comparison showed that the positive rate of occupational stress in divorced (50.0%) or married (32.0%) workers was higher than that in single (27.1%) workers, and higher in operation workers (30.6%) than in other types of work (20.5%) (P＜0.05). The trend chi-square results showed that the positive rate of occupational stress increased linearly with the increase of age, length of service, BMI, or monthly income (P＜0.05). The results of logistic regression analysis after adjustment showed that workers who worked ＞40 h a week had a higher risk of occupational stress than those who worked ≤40 h a week, and the OR (95%CI) was 1.909 (1.135, 3.211); the workers of other types of work had a lower risk of reporting occupational stress than operation workers, and the OR (95%CI) was 0.513 (0.272, 0.968); the workers with noise exposure had a higher risk of occupational stress than the workers without, and the OR (95%CI) was 2.457 (1.070, 5.642). Conclusion The positive rate of occupational stress among employees in this petrochemical enterprise is high. Among them, operators, working hours per week＞40 h, and noise exposure may increase the incidence of occupational stress. The enterprise should actively take measures to reduce the occurrence of occupational stress among employees.

Moonlighting and physician residents' compensation: is it all about money? A cross-sectional Brazilian study

ABSTRACT BACKGROUND: Moonlighting is a largely discussed, however under-explored, subject among physician residents. OBJECTIVES: To analyze the frequency of moonlighting and its related factors. DESIGN AND SETTING: This cross-sectional study enrolled medical residents from all geographical regions of Brazil. METHODS: A web-based structured closed-ended survey was applied that explored the frequency and type of moonlighting, residency programs characteristics, and psychological distress. The questionnaire was published on social networks. RESULTS: The completion rate was 71.4% (n = 1,419) and 37.7% were males aged 28.8 ± 3.2 (mean ± standard deviation) years, and 571 (40.2%) were post-graduate year (PGY) 1. There were residents from 50 medical specialties (the most common training area was clinical, 51.9%). A total of 80.6% practiced moonlighting, with an average weekly workload of 14.1 ± 9.4 h, usually overnight or in weekend shifts. Factors related to it were being PGY-2 or higher (adjusted odds ratio = 3.90 [95% confidence interval = 2.93-5.18], logistic regression), lower weekly residency duty hours (0.98 [0.97-0.99]), and a higher salary (1.23 [1.08-1.40]). In contrast, perception of a "fair/adequate" compensation was influenced by age (1.02 [1.01-1.02]), not being single (1.05 [1.01-1.10]), and residency duty hours (1.51 [1.22-1.88]). Depression, anxiety, diurnal somnolence scores, and work-personal life conflicts were not correlated with moonlighting status. CONCLUSION: Moonlighting frequency is high, and it is related to higher PGY, briefer residency duty hours, and the perception that remuneration should be higher. This study provides insights into the motivations for moonlighting and effort-reward imbalance.

O desequilíbrio esforço-recompensa está associado à hipertensão arterial entre servidores públicos brasileiros? Resultados do ELSA-Brasil / Is the effort-reward imbalance associated with hypertension among Brazilian civil servants? Results from the ELSA-Brasil study

Resumo Objetivos: analisar a associação entre o estresse no trabalho, segundo o modelo de desequilíbrio esforço-recompensa (DER), e a hipertensão arterial (HA), assim como investigar o papel modificador de efeito do excesso de comprometimento (EC) e do sexo. Métodos: análise seccional de dados de trabalhadores(as) ativos que participaram da segunda onda de coleta de dados (2012-2014) do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). O estresse no trabalho foi mensurado pela versão brasileira da escala de DER, composta por três dimensões: esforço, recompensa e EC. A HA foi definida como níveis de pressão arterial sistólica/diastólica ≥ 140/90 mmHg ou uso de medicamento anti-hipertensivo. Empregou-se regressão logística, bruta e ajustada por potenciais fatores de confusão. As interações multiplicativas foram investigadas. Resultados: participaram 9.465 servidores, 51,9% do sexo feminino. A prevalência de HA foi de 34,9%. No modelo ajustado, associações limítrofes foram identificadas entre o DER (razão>1) e maior EC com maiores chances de HA (OR: 1,11; IC95%: 1,00; 1,24; e OR: 1,13; IC95%: 1,01; 1,26, respectivamente). A análise de interação indicou que sexo e EC não são modificadores de efeito. Conclusão: DER e EC associaram-se a maiores chances de HA, após ajuste. Sexo e EC não foram modificadores de efeito.

Abstract Objectives: to evaluate the association between job stress, according to the effort-reward imbalance (ERI) model, and hypertension (HTN), as well as to investigate the effect modifier role of overcommitment (OC) and sex. Methods: cross-sectional analysis of data from active workers who participated in the second data collection wave (2012-2014) of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Job stress was measured by the ERI scale - Brazilian version, comprising three dimensions: effort, reward, and OC. HTN was defined as systolic or diastolic blood pressure levels ≥ 140/90 mmHg or antihypertensive medication use. Associations were estimated by logistic regression, crude and adjusted for potential confounding factors. Multiplicative interactions were investigated. Results: a total of 9,465 civil servants participated in the study, 51.9% females. HTN prevalence was 34.9%. The adjusted model identified borderline associations between ERI (ratio > 1) and higher OC with higher odds of HTN (OR = 1.11, 95%CI = 1.00; 1.24; and OR = 1.13; 95%CI = 1.01; 1.26, respectively). Interaction analysis indicated no differences in associations according to sex and OC. Conclusion: results show that ERI and OC are associated with higher odds of HTN after adjustment. Sex and OC were not effect modifiers.

The influence of subjective comfort of working environment on occupational stress of railway station workers / 中华劳动卫生职业病杂志

Objective: To explore the influential factors of job stress suffered by workers in railway stations, the level of job stress of were measured and subjective comfort of employees targeting to working environment were reported. Methods: In March 2019, a cluster sampling study was designed to collect the personal characteristics, job characteristics and subjective comfort degree of working environment of 432 employees in Chongqing railway stations. Meanwhile, job stress was assessed using the effort-reward imbalance scale. Chi-square test was used to compare the difference of occupational stress detection rate among different stratified factors such as occupational characteristics. Logistic regression was applied to analyze the influential factors of occupational stress. Results: The detection rate of job stress of workers in the railway stations was 31.02% (134/432) . The detection rate of job stress was higher among the divorced workers in railway stations, those earning less than 5, 000 yuan per month, those with 10-20 years' length of service, those who worked as a conductor and other workers including baggageman, station master on duty and assistant engineer (χ(2)=9.61, 14.76, 23.28, 11.06, P=0.008, 0.002, 0.000, 0.011) . The detection rate of job stress was higher among those whose working environment subjective feelings were uncomfortable, the differences were statistically significant (P<0.001) . The results showed that the occupational stress of the staff in the railway stations was influenced by their subjective feeling of air quality, noise and Space Layout (P<0.05) . The risk factors of occupational stress were air quality, noise and uncomfortable space layout (OR=0.571, 0.068, 0.441, P=0.051, 0.054, 0.007) . Conductor, other (Bellboy, Duty Station Master, assistant engineer) were the risk factors of occupational stress (OR=1.884, 2.703, P=0.065, 0.019) . The employees of station A and station B were the risk factors of occupational stress (OR=4.681, 1.811, P=0.002, 0.067) . Conclusion: The higher detection rate of job stress of workers in the railway stations is correlated with the subjective comfort degree of the working environment of the workers.

Effects of occupational stress and mental health on work-related musculoskeletal disorders in coal mine workers in Xinjiang / 环境与职业医学

Background The occurrence of musculoskeletal disorders in coal mine workers remains high, and psychological factors are one of the important factors. Objective To explore the occupational stress level, mental health status, and prevalence of work-related musculoskeletal disorders (WMSDs) of coal miners in Xinjiang, and to analyze the effects of occupational stress and mental health on WMSDs. Methods From August 2018 to August 2019, 1300 workers of 4 coal mines were selected by cluster sampling method. Musculoskeletal Disorders Questionnaire, Effort-Reward Imbalance (ERI) Scale, Self Reporting Inventory (SCL-90) were used to investigate the prevalence of WMSDs, occupational stress, and mental health. Results A total of 1177 valid questionnaires were collected, with a valid rate of 90.5%. The prevalence rate of WMSDs was 66.4%, the positive rate of occupational stress was 50.2%, and the positive rate of psychological symptoms was 53.4%. The M (P25, P75) ERI score was 1.0 (0.9,1.2), and the M (P25, P75) SCL-90 score was 138.0 (117.0,184.0). The prevalence rate of WMSDs in ≥3 sites was 45.0% in the occupational stress group and 46.0% in the positive psychological symptoms group. The results of binary logistic regression analysis showed that reporting occupational stress (OR=1.835, 95%CI: 1.380-2.440) and positive psychological symptoms (OR=1.461, 95%CI: 1.083-1.969) were positively associated with the prevalence of WMSDs; those being female (OR=2.393, 95%CI: 1.544-3.709), aged≥30 years (OR30-＜40=2.344, 95%CI: 1.507-3.645; OR40-＜50=2.395, 95%CI: 1.541-3.723; OR50-60=5.115, 95%CI: 2.872-9.111), with length of service>15 years (OR=2.283, 95%CI: 1.537-3.392), and being coal diggers (OR=1.591, 95%CI: 1.070-2.365) showed higher risks of reporting WMSDs; those with education level at high school and above (ORhigh school=0.399, 95%CI: 0.279-0.571; ORcollege and above=0.220, 95%CI: 0.157-0.310), and monthly income>8000 yuan (OR=0.364, 95%CI: 0.227-0.582) showed lower risks of reporting WMSDs. The results of structural equation model showed that in model 1 with mental health as the intermediate variable, occupational stress and mental health directly affected WMSDs, and the standardized path coefficients (β) were 0.10 and 0.25 respectively; ERI also directly affected mental health with a β of 0.20. In model 2 with WMSDs as the intermediate variable, ERI and WMSDs directly affected mental health, and the β values were 0.16 and 0.25 respectively; ERI also directly affected WMSDs with a β of 0.16. Conclusion The prevalence rate of WMSDs in selected coal mine workers is high, and occupational stress and mental health affect the occurrence of WMSDs.

Analysis of occupational identity among family doctor teams and its influencing factors in Chengdu / 环境与职业医学

Background The contracted family doctor services are the embodiment of the implementation of the new medical reform policy, and the transformation of the grass-roots health service mode. Studies have proved that the occupational stress in medical staff was at a high level. The enhancement of professional identity will contribute to strengthen team building，alleviate job burnout, and reduce turnover intention of family doctors. Objective To investigate the current situation of occupational identity among family doctor teams in Chengdu, to examine potential influencing factors of occupational identity, and to provide a reference for promoting career development and team building of family doctor teams. Methods Multi-stage random cluster sampling was adopted to enroll study participants form 46 primary healthcare centers where family doctor contract services were implemented among 23 districts and counties in Chengdu between March 4 and 26, 2021. A total of 2 681 family doctors participated in this survey. A self-reported survey was conducted to collect participants' demographic and occupational data. The Effort-Reward Imbalance (ERI）questionnaire was implemented to assess occupational stress. The Professional Identity Scale was used to appraise occupational identity. Results A total of 2 327 valid questionnaires were collected, with a valid recovery rate of 86.80%, involving 1 715 females (73.7%) and 612 males (26.3%), with dominant age groups of 26−35 years (43.3%) and 36−45 years (30.4%), a high proportion of being married (82.8%), having college (36.0%) and undergraduate (47.3%) education, a high proportion of primary titles (66.0%) and informal work contract (66.1%). About 88.7% of family doctor team workers reported occupational stress. The average score of occupational identity was (3.68±0.62) points. There were significant differences in occupational identity scores among different professional title, work contract, working years in medical institutions, income, and effort/reward ratio (EER) groups (P < 0.05). ERR was negatively correlated with occupational identity (rs=−0.495, P<0.05）. The multiple regression model showed that occupational identity score in the non-staffed participants was lower than the score in the staffed ones (OR=0.429, 95%CI: 0.299−0.825). The occupational identity score in the participants having associate senior title or above was higher than in without professional title (OR=1.424, 95%CI: 1.194−2.328). The longer the working years, the higher the occupational identity score among the participants. The score of the more than 20 working years group was 1.820 times that of the less than 5 working years group (95%CI: 1.342−2.543). The higher the income, the higher the occupational identity score. The score of the 9001−12000 yuan per month group was 1.977 times that of the 1000−3000 yuan per month group (95%CI: 0.811−9.696) , and the score of the more than 12000 yuan per month group was 2.283 times that of the 1000−3000 yuan per month group (95%CI: 1.199−10.267）. Conclusion The family doctor team workers generally report occupational stress, and their occupational identity is at a medium level in Chengdu. Relevant managers should implement intervention measures against the main influencing factors to reduce their work tension and improve their occupational identity.

Characterization of young graduates perceiving underemployment: Assessment of well-being and discomfort associated with this perception / Caracterización de jóvenes egresados que perciben subempleo: evaluación del bienestar y malestar asociadas a esta percepción

Resumen Investigaciones previas han demostrado que el subempleo subjetivo está inversamente asociado a la satisfacción laboral, el bienestar psicológico y la salud. Hasta donde conocemos, este es el primer estudio que explora el subempleo subjetivo en egresados de pregrado en Colombia. Ciento cuarenta y dos trabajadores participaron en un estudio correlacional y comparativo. Los resultados replicaron hallazgos previos: a medida que aumentaba la percepción de subempleo subjetivo, disminuían la satisfacción laboral y la satisfacción con la vida en general. Se encontraron diferencias significativas en los indicadores de satisfacción laboral y satisfacción con la vida en general entre quienes perciben subempleo y quienes no. Por último, se discute el potencial ro del subempleo subjetivo en la salud de los empleados.

Abstract Previous research has shown that subjective underemployment is inversely associated to job satisfaction, psychological well-being and health. To our knowledge, the current is the first study that explores subjective underemployment in undergraduates in Colombia. One hundred and forty-two workers participated in a correlational, and comparative study. Results replicated previous findings: as subjective underemployment perception increased, job satisfaction and general life satisfaction decreased. Significant differences were found in the indicators of job satisfaction and general life satisfaction among those who perceive underemployment and those who do not. Finally, the potential role of subjective underemployment on employees' health is discussed.

Effects of two occupational stress models on depressive symptom of employees in a mould-producing enterprise / 中国职业医学

OBJECTIVE: To explore the influencing factors of depressive symptom of employees in a mould-producing enterprises using two occupational stress models. METHODS: A total of 457 employees in a mould-producing enterprise were selected as study subjects using cluster sampling method. The Center for Epidemiological Study-Depression Scale, the Chinese version of Job Demand Content Questionnaire and the Effort-Reward Imbalance Questionnaire were used to investigate the level of depressive symptom and occupational stress by the job demand control(JDC) model and effort reward imbalance(ERI) model. RESULTS: Among the 457 employees, the median score of depressive symptom was 11.00, the detection rate of depressive symptom in the subjects was 23.4%(107/457). The incidence of occupational stress by the JDC and ERI models was 78.3%(358/457) and 62.6%(286/457), respectively. The rate of depressive symptom was statistically higher in the high occupational stress group than that of the low occupational stress group by the ERI model(26.6% vs 18.1%, P<0.05). The multivariate logistic regression analysis showed that both marital status and monthly income were influencing factors of depressive symptom by the JDC model(P<0.05). The marital status, monthly income and occupational stress were influencing factors of depressive symptom by the ERI model(P<0.05). The risk of depressive symptom was statistically higher in the high occupational stress group than that of the low occupational stress group(P<0.05). CONCLUSION: Employees in mould-producing enterprise have some depressive symptom. The marital status, monthly income and occupational stress by the ERI model are the main influencing factors of depressive symptom.

Objective@#To detect the prevalence of sleep disorders among metro staff and to analyze influencing effects of effort reward imbalance (ERI) on it.@*Methods@#In January 2015, subway driver, dispatcher and station operator from Guangzhou subway were selected as the research object in the whole group sampling method. A total of 1200 questionnaires were distributed and 1124 were valid questionnaires, and the effective questionnaire recovery rate was 93.7%. Based on the effort reward imbalance questionnaire and the self-administered sleep questionnaire, the data of the general demographic characteristics, life satisfaction, occupational stress and sleep status of the respondents were collected. Epi.data3.1 and spss19.0 were used for analyzing.@*Results@#A total of 1124 subway employees were surveyed, with an average age of (28±5) years; the working age was (4.5±3.6) years. ERI occupied 24.7% (278/1124) of the study population and sleep disorders as 42.2% (474/1124) . Single factor analysis showed that marital status, educational level, work position, life satisfaction and ERI could significantly influence sleep disorders of metro staff (P<0.05) . Logistic regression showed that higher effort (adjusted OR=2.56, 95%CI: 1.79-3.68) , lower reward (adjusted OR=1.90, 95%CI: 1.34-2.68) and ERI (adjusted OR=2.33, 95%CI: 1.69-3.22) could increase the risk of sleep disorders after the confounding factors were controlled. ERI (adjusted OR=2.89, 95% CI: 1.80-4.64) , and over commitment (adjusted OR=4.64, 95%CI: 2.81-7.68) could influence the risk of sleep disorders independently when over commitment was evaluated as a moderating variable.@*Conclusion@#Occupational stress as ERI could influence the risk of sleep disorders among metro staff. The situation should not be neglected for occupational health of metro staff.

Assessing occupational stress level and its influencing factors in medical radiologists by two models / 中国职业医学

OBJECTIVE: To explore the status of occupational stress and its influencing factors in medical radiation workers using two occupational stress measurement models. METHODS: A total of 632 medical radiation workers from Guangdong Province were selected as the study subjects using cluster sampling method. Chinese version of Job Content Questionnaire and Effort Reward Imbalance Questionnaire were used to assess occupational stress with job demand-control( JDC) and effort-reward imbalance( ERI) models. RESULTS: The rate of occupational stress in the study subjects was 43. 8%( 277/632) using the JDC model. The rate of occupational stress was 38. 6%( 244/632) using the ERI model. The multivariate logistic analysis results showed that the risk of JDC occupational stress was higher in workers with more than 8 hours work daily and more than 40 hours weekly( P < 0. 01). The risk of ERI occupational stress was higher in the workers with age of30. 0-40. 0,public medical institutions,daily work more than 8 hours and weekly work more than 40 hours( P < 0. 01).CONCLUSION: Under the two theoretical models,medical radiation workers have a certain degree of occupational stress. The age,medical institution type,daily and weekly work hours are the main factors affecting occupational stress.

Association of effort-reward imbalance and insomnia in steel workers: a structural equation modeling analysis / 中国职业医学

OBJECTIVE: To explore the relationship between Effort-Reward Imbalance(ERI) and insomnia using structural equation modeling. METHODS: A total of 5 769 steel workers from an iron and steel company were selected as study objects by convenient sampling method. The Effort-Reward Imbalance Scale and Five-Item Athens Insomnia Scale were used to investigate their ERI and insomnia respectively. A structural equation modeling was constructed to analyze the relationship between ERI and insomnia. RESULTS: The scores of work effort and internal investment were positively correlated with the score of insomnia [the Spearman correlation coefficient(r_S) were 0.127 and 0.122 respectively, P<0.01]. Work reward scores were negatively correlated with the score of insomnia(r_S=-0.126, P<0.01). We successfully construct a structural equation model between ERI and insomnia in steel workers. According to this model, work effort, work reward and internal investment had direct effect on insomnia [the standardized path coefficient(β) were 0.065,-0.067 and 0.091 respectively, P<0.05]. Work effort and work reward have direct effect on insomnia(the β were 0.048 and-0.010 respectively, P<0.05). CONCLUSION: ERI increases the risk of insomnia. Both effort and internal investment have positive effect on insomnia, while reward has negative effect on insomnia.

Objective@#To investigate the high occupational stress and its influencing factors in traffic police in Shanghai.@*Methods@#728 traffic police were selected as the study subjects, and the《Occupational Health Questionnaire》was used to investigate and evaluate their job demand-control (JDC) and effort-reward imbalance model (ERI) occupational stress situation respectively. The related influencing factors were analyzed.@*Results@#The prevalence rates of high occupational stress in JDC and ERI models were 74.6% (543/728) and 51.5% (375/728) . The influencing factors of JDC were education, marriage, average weekly hours (χ2=16.82, 10.04, 18.71, P<0.05) , and The influencing factors of ERI were gender, age, marriage, real monthly income level, education, work experience, and average weekly hours (χ2=7.02, 26.18, 6.73, 50.42, 4.75, 26.61, 112.98, 6.19, P<0.05) . The JDC multivariate logistic analysis indicated that the risk of occupational stress of married police was 2.81 times as high as that of Unmarried ones. The risk of occupational stress of traffic police with more education was 1.92 times as high as that of low eduacation, average weekly working 41-50 hours and≥51 hours was 2.53, 3.12 times as high as that of ones with average working 40 hours, respectivly. Meanwhile, the ERI multivariate logistic analysis indicated that high income level is the protective factor of occupational stress. The traffic police with 15-<20 working years were more likely to occur higher occupational stress. The traffic police with the more average weekly hours had greater possibility of higher occupational stress.@*Conclusion@#The main influencing factors of JDC and ERI are marriage, real monthly income level, education, work experience, and average weekly hours.

An Analysis of Individual and Social Factors Affecting Occupational Accidents

BACKGROUND: Workforce health is one of the primary and most challenging issues, particularly in industrialized countries. This article aims at modeling the major factors affecting accidents in the workplace, including general health, work-family conflict, effortereward imbalance, and internal and external locus of control. METHODS: A cross-sectional study was conducted in Esfahan Steel Company in Iran. A total of 450 participants were divided into two groups—control and case—and the questionnaires were distributed among them. Data were collected through a 7-part questionnaire. Finally, the results were analyzed using SPSS 22.0 and Amos software. RESULTS: All the studied variables had a significant relationship with the accident proneness. In the case group, general health with a coefficient of −0.37, work-family conflict with 0.10, effort-reward imbalance with 0.10, internal locus of control with −0.07, and external locus of control with 0.40 had a direct effect on occupational stress. Occupational stress also had a positive direct effect on accident proneness with a coefficient of 0.47. In addition, fitness indices of control group showed general health (−0.35), work-family conflict (0.36), effort-reward imbalance (0.13), internal locus of control (−0.15), and external locus of control (0.12) have a direct effect on occupational stress. Besides, occupational stress with a coefficient of 0.09 had a direct effect on accident proneness. CONCLUSION: It can be concluded that although previous studies and the present study showed the effect of stress on accident and accident proneness, some hidden and external factors such as workefamily conflict, effortereward imbalance, and external locus of control that affect stress should also be considered. It helps industries face less occupational stress and, consequently, less occurrence rates of accidents.

Occupational stress and job dissatisfaction with health work

Abstract Objective: The purpose of this study is to evaluate the association between psychosocial aspects at work and dissatisfaction among health workers in five cities in Bahia, Brazil. Methods: The evaluation was based on different models proposed to measuring occupational stress and possible combinations between them: demand-control model (DCM) and effort-reward imbalance (ERI). We conducted a cross-sectional epidemiological study including 3084 health workers. The analysis considered the association between partial/full/partial (combined) occupational stress models (the variable "exposure") and job dissatisfaction (the variable "outcome"). Results: Dissatisfaction rate was 26%. Full DCM and ERI models were better than partial ones to investigate job dissatisfaction. After adjustments, the combined models presented more robust measures of prevalence ratio than models evaluated separately (PR 2.93; CI 2.26-3.80). Conclusions: The combination of models has shown greater capacity to identify situations of job dissatisfaction and provided more potential information to support actions for workers' health. (AU)

Situações de desequilíbrio entre esforço-recompensa e transtornos mentais comuns em trabalhadores da atenção básica de saúde / Situations of imbalancing between stress-rewards and common mental disorders in basic health care workers / Situaciones de desequilibrio entre esfuerzo-recompensa y transtornos mentales comunes en trabajadores de la atención básica de salud

Resumo Estudo da associação entre transtornos mentais comuns e situações de desequilíbrio entre esforços e recompensas em trabalhadores da atenção básica de saúde realizada em distrito sanitário de Salvador, na Bahia. Foram estudados trabalhadores que estavam em exercício profissional nas unidades de saúde do distrito, em 2012. Estudo transversal, com quatrocentos do total de 509 trabalhadores. Para avaliação de esforço e recompensa no trabalho, utilizou-se o Effort-Reward Imbalance. O Self-Reporting Questionnaire mensurou os transtornos mentais comuns. A prevalência de transtornos mentais comuns foi de 21%; 46,2% dos trabalhadores vivenciavam situações de desequilíbrio esforço-recompensa no trabalho. A prevalência de transtornos mentais comuns foi mais elevada na situação de desequilíbrio esforço-recompensa (26,9%) e no grupo dos trabalhadores operacionais (33,8%). A análise de correspondência indicou relação entre desequilíbrio esforço-recompensa e transtornos mentais comuns na primeira dimensão. O modelo de regressão logística log-binomial evidenciou associação positiva entre desequilíbrio esforço-recompensa e transtornos mentais comuns (razão de prevalência ajustada=1,91). Trabalhadores expostos a situações de desequilíbrio esforço-recompensa no trabalho apresentaram maior frequência de adoecimento mental. Os resultados reforçam a necessidade de intervir na gestão e organização do trabalho quanto às demandas dos serviços, condições precárias do trabalho e formas de recompensa ou reconhecimento.

Abstract This study focused the association between common mental disorders and situations of imbalance between efforts and rewards in primary health care workers held in sanitary district, municipality of Salvador, Bahia, Brazil. The study included workers who were active in the district's health in 2012. A cross-sectional study, with 400 out of 509 workers, was conducted. Effort-Reward Imbalance was used to evaluate effort and reward at work and the Self-Reporting Questionnaire measured common mental disorders. The prevalence of common mental disorders was 21%, 46.2% of studied workers experienced situations of work-reward imbalance at work. The highest prevalence of common mental disorders was observed in the effort-reward imbalance (26.9%) and in the operational workers group (33.8%). Correspondence analysis indicated a relationship between effort and reward imbalance and common mental disorders in the first dimension. The log-binomial logistic regression model showed a positive association between effort and reward imbalance and common mental disorders (adjusted prevalence ratio=1.91). Workers exposed to situations of effort-reward imbalance at work showed a higher frequency of mental illness. It is necessary to intervene in the management and organization of the work regarding the demands of the services, precarious work conditions and forms of reward or recognition.

Resumen Estudio de la asociación entre trastornos mentales comunes y situaciones de desequilibrio entre esfuerzos y recompensas en trabajadores de la atención básica de salud realizada en distrito sanitario, municipio de Salvador, Bahia, Brasil, siendo considerados trabajadores aquellos en ejercicio profesional en las unidades de salud del distrito. Estudio transversal analítico, con 400 del total de 509 trabajadores. Para la evaluación de esfuerzo y recompensa en el trabajo se utilizó el Effort-Reward Imbalance y el Self-Reporting Questionnaire (SRQ-20) mensuró los Trastornos Mentales Comunes. La prevalencia de trastornos mentales comunes fue del 21%, el 46,2% de ellos experimentando situaciones de desequilibrio esfuerzo-recompensa en el trabajo. La prevalencia de Trastornos Mentales Comunes más elevada en la situación de desequilibrio esfuerzo-recompensa (26,9%) y en el grupo de los trabajadores operativos (33,8%). El análisis de correspondencia indicó relación entre desequilibrio esfuerzo y recompensa y trastornos mentales comunes en la primera dimensión. El modelo de regresión logística log-binomial evidenció asociación positiva entre desequilibrio esfuerzo y recompensa y Trastornos Mentales Comunes (razón de prevalencia ajustada=1,91). Los trabajadores expuestos a situaciones de desequilibrio esfuerzo y recompensa en el trabajo presentaron una mayor frecuencia de enfermedad mental. Es necesario intervenir en la gestión y organización del trabajo en cuanto a las demandas de los servicios, condiciones precarias del trabajo y formas de recompensa o reconocimiento.

Influencing factors on two types of occupational stress in workers of electronics manufacturing industry / 中国职业医学

OBJECTIVE: To investigate occupational stress and its influencing factors in workers of electronic manufacturing.METHODS: The judgment sampling method was used to select 2 251 workers as study subjects. The Simple Occupational Stress Questionnaire and the Effort-Reward Imbalance( ERI) Questionnaire were used to investigate job demand-control(JDC) and ERI occupational stress respectively. RESULTS: Among the 2 251 workers,the prevalence rates of high occupational stress in JDC and ERI models were 56. 4% and 10. 1%,respectively. The positive rate of JDC occupational stress was higher than that of ERI( P < 0. 01). The multivariate logistic analysis indicated that workers with assembly line had higher risk of JDC and ERI occupational stress than workers without assembly line( P < 0. 05). Workers with labor dispatching had higher risk of JDC and ERI occupational stress than workers with long-term contract( P < 0. 05). Workers exposed to occupational hazards had higher risk of JDC and ERI occupational stress than workers not exposed to occupational hazards( P < 0. 05). Workers with disease had higher risk of JDC and ERI occupational stress than healthy workers( P < 0. 05). CONCLUSION: JDC is the main occupational stress model in workers of electronics manufacturing factory. The main influencing factors are assembly line,labor dispatching,weekly work time,exposure to occupational hazards and illness.

Association of occupational stress with job burnout and depression tendency in workers in Internet companies / 中华劳动卫生职业病杂志

Objective@#To investigate the association of occupational stress with job burnout and depression tendency in workers in Internet companies. @*Methods@#From July to November, 2016, the cross-sectional method was used to perform a questionnaire survey of 3603 workers in 35 Internet companies in Beijing, Shandong Province, and Zhejiang Province in China, and the association of occupational stress with job burnout and depression tendency was analyzed. @*Results@#Among these workers, 63.70% had occupational stress with job demand-control (JDC) and 34.60% had occupational stress with effort-reward imbalance (ERI) ; among the workers engaged in sales, 75.63% had occupational stress with JDC and 62.70% had occupational stress with ERI. Of all workers, 10.69% had job burnout, and among the workers engaged in sales, 22.12% had job burnout. Of all workers, 18.79% had the tendency of moderate-to-severe or severe depression, and among the workers engaged in sales, 46.13% had such tendency. Occupational stress with JDC increased the risk of job burnout and depression (odds ratio[OR]=3.52 and 1.85, P<0.05) , and occupational stress with ERI also increased the risk of job burnout and depression (OR=8.24 and 5.59, P<0.05) . In addition, irregular diet and insomnia were risk factors for job burnout; age ≥41 years, low income, sales position, working time spent on the screen ≥10 hours/day, insomnia, and poor self-evaluated health status were risk factors for depression tendency. @*Conclusion@#Occupational stress with JDC and ERI increases the risk of job burnout and depression tendency, and among the workers in Internet companies, the workers engaged in sales have the most severe occupational stress, job burnout, and depression tendency.

Effect of occupational stress on recurrent spontaneous abortion in women of childbearing age / 中华劳动卫生职业病杂志

Objective@#To investigate the influence of occupational stress on recurrent spontaneous abortion (RSA) in women of childbearing age.@*Methods@#From January to December, 2017, 75 working women of childbearing age (25-35 years) who were admitted to a provisional hospital in Lanzhou, China and diagnosed with RSA were assigned into patient group. At a 1∶4 ratio, 300 age-matched working women who had normal first pregnancy were randomly selected as controls. A case-control study was conducted by a self-made questionnaire and the effort-reward imbalance scale. The impact of occupational stress on RSA in women of childbearing age was analyzed by evaluation of occupational harmful factors, regularity, effort-reward ratio, and sleep quality.@*Results@#There were significant differences in the distribution of sleep, daily exercise, night shift, extrinsic-effort/low-reward score, and effort/low-reward score between the patient group and the control group (χ2=7.867, P<0.05; χ2=7.377, P<0.05; χ2=3.714, P<0.05; χ2=6.651, P<0.05; χ2=8.556, P<0.05) . With controlled factors such as general conditions and living habits, logistic regression analysis showed that poor sleep quality and high-effort/low-reward were risk factors for RSA (odds ratio[OR]=1.462, 95% confidence interval[CI]: 1.032~2.073; OR=3.253, 95%CI: 1.169~9.053) . A regular work was a protective factor against RSA (OR=0.644, 95%CI: 0.438-0.946) .@*Conclusion@#In occupational stress, irregular working hours, lack of sleep, and high-effort/low-reward are risk factors for RSA. Working women of childbearing age should ensure adequate sleep, pay attention to effort-reward balance, and make a regular work schedule.

The Factorial Structure and Psychometric Properties of the Persian Effort-Reward Imbalance Questionnaire

BACKGROUND: With global changes in the current state of work and employment, the role of health-adverse psychosocial work environments has received increasing attention in developed as well as in rapidly developing countries. Thus, there is a need to apply valid measurement tools for monitoring and preventive purposes. This study aims to examine the factorial structure and psychometric properties of the Persian version of the effort-reward imbalance (ERI) questionnaire, assessing one of the internationally leading concepts of stressful work. METHODS: This descriptive cross-sectional study of a random sample of 202 white collar employees in an industrial company in Iran analyzes the ERI scales by exploratory and confirmatory factor analysis. Moreover, aspects of construct and criterion validity are tested. To this end, correlations of ERI scales with subscales of organizational injustice, a complementary work stress model, and also the correlations of ERI scales with a questionnaire assessing psychosomatic symptoms are performed. RESULTS: Internal consistency of the three ERI scales was satisfactory (Cronbach α effort: 0.76, reward: 0.79, overcommitment: 0.75). Fit indices of confirmatory factor analysis pointed to an adequate representation of the theoretical construct (e.g., adjusted goodness of fit index (AGFI): 0.73, goodness of fit index (GFI): 0.78). Negative correlations with subscales of organizational injustice supported the notion of construct validity of the ERI scales, and positive correlations of ERI scales with psychosomatic symptoms indicated preliminary criterion validity. CONCLUSION: The Persian version of the ERI questionnaire has acceptable psychometric properties and can be used as a valid instrument in research on this topic.

Effort–reward Imbalance at Work, Parental Support, and Suicidal Ideation in Adolescents: A Cross-sectional Study from Chinese Dual-earner Families

BACKGROUND: In contemporary China, most parents are dual-earner couples and there is only one child in the family. We aimed to examine the associations of parents' work stress with suicidal ideation among the corresponding adolescent. We further hypothesized that low parental support experienced by adolescents may mediate the associations. METHODS: Cross-sectional data from school students and their working parents were used, with 907 families from Kunming City, China. Stress at work was measured by the effort–reward imbalance questionnaire. Perceived parental support was assessed by an item on parental empathy and their willingness to communicate with the adolescent. Suicidal ideation was considered positive if students reported thoughts about suicide every month or more frequently during the previous 6 months. Logistic regression was used to examine the associations. RESULTS: We observed that parents' work stress was positively associated with low parental support, which was in turn associated with adolescent suicidal ideation. The odds ratio for parents' work stress and adolescent suicidal ideation was 2.91 (95% confidence interval: 1.53–5.53), and this association was markedly attenuated to 2.24 (95% confidence interval: 1.15–4.36) after additional adjustment for parental support. Notably, mothers' work stress levels exerted stronger effects on children's suicidal ideation than those of fathers. CONCLUSION: Parents' work stress (particularly mother's work stress) was strongly associated with adolescent's suicidal ideation, and the association was partially mediated by low parental support. These results need to be replicated and extended in prospective investigations within and beyond China, in order to explore potential causal pathways as a basis of preventive action.
