Impact of Occupational Stress on Clinical Performance among Nurses: A Case Study of District Multan

There is an increasing attention to identify the occupational stressors on clinical performance among nurses due to the shortfall of paramedical staff especially nurses to an alarming extent globally. We develop a research framework to examine the impact of occupational stress on nurses’ clinical performance. A cross-sectional research design was used for data collection (n= 251). Data collection was accomplished by conducting a survey as a method. Data were analyzed through SPSS. The results indicate that occupational stress is negatively correlated with clinical performance among nurses. Work demand, work-family conflicts, occupational hazards, and occupational issues have a significant impact on nurses’ clinical performance. Moreover, interpersonal relationships and workplace violence are found to be the insignificant impact on clinical performance. Demographic variables like marital status and computer skills have significant differences in occupational stress and clinical performance. Married nurses have a higher level of occupational stress and lower level clinical performance as compared to unmarried. Nurses with computer skills have low occupational stress and higher clinical performance than those without computer skills. The results of the study have theoretical as well as practical implications, needed to be addressed on a priority basis.

Evaluation of occupational stress and job performance in Iranian nurses: the mediating effect of moral and emotional intelligence

BackgroundNurses’ Job performance could be affected by occupational stress. Previous studies reported contradictory results in this regard. Factors such as moral and emotional intelligence could impact occupational stress. However, the extent of any mediating effect is unclear. Thus, this study aimed to determine the effect of occupational stress on nurses’ Job performance and the mediating impact of moral and emotional intelligence.MethodsThis cross-sectional study was conducted in Urmia teaching hospitals (Imam Khomeini, Motahari, Taleghani, Kosar, and Seyed al-Shohada Hospitals). Six hundred twenty-one nurses were selected using quota sampling from February 2022 to April 2022. Data were collected using demographic questionnaires, the Nursing Stress Scale, Paterson’s Job Performance Questionnaire, Siberia Schering’s Emotional Intelligence Standard Questionnaire, and Lennik and Keil’s Moral Intelligence Questionnaire. Data were analyzed using SPSS ver. 23 and SmartPLS ver. 2.ResultsOccupational stress had a positive, direct, and minor effect on nurses’ job performance (β = 0.088, t-value = 2.245, p < 0.01). Occupational stress had a positive and direct impact on moral intelligence (β = 0.161, t-value = 2.945, p < 0.01) and a negative and direct effect on emotional intelligence (β = -0.351, t-value = 7.484, p < 0.01). Occupational stress negatively and indirectly affected job performance through moral intelligence (β =—0.560, t-value = 14.773, p < 0.01). Occupational stress also positively and indirectly impacted job performance through emotional intelligence (β = 0.098, t-value = 2.177, p < 0.01).ConclusionsOccupational stress slightly affects nurses’ job performance, and emotional and moral intelligence mediates the impact of occupational stress and improves nurses’ job performance. Low occupational stress improves nurses’ job performance, but too much occupational stress could harm nurses’ job performance. Healthcare administrators should work to help reduce nurses’ occupational stress and improve their job performance by adopting practical strategies to help nurses manage and control their stress. Holding stress reduction classes, eliminating the nursing shortage, reducing working hours, reducing workload, and providing financial and spiritual support to nurses would be recommended. It is also recommended to provide theoretical and practical emotional and moral intelligence-oriented courses for nursing students and hold training workshops for nurses to improve their emotional and moral intelligence.

MEDIATING ROLE OF EMOTIONAL INTELLIGENCE BETWEEN THE RELATIONSHIP OF OCCUPATIONAL STRESS AND CLINICAL PERFORMANCE AMONG NURSES

Nurses are going through the extensive physical and emotional burden, directing them to occupational stress. The shortfall of nurses is alarming after the pandemic of COVID -19. This study aimed to explore the ways to reduce occupational stress among nurses. It will help to alleviate their clinical performance. Frame-work of emotional intelligence is used as a mediating variable between occupational stress and clinical performance among nurses. This cross-sectional study was carried out in Multan, Pakistan in 2022. The population was nurses (currently employed) from four main hospitals (C.M.H, Nishter, Children Complex, and Cardiology Center). The sample size was 251 respondents and the survey method was used to gain data. Data were analyzed through SPSS. The results indicate that occupational stress is negatively correlated with emotional intelligence and clinical performance among nurses. Emotional intelligence is positively correlated with clinical performance. The significant impact of occupational stress on clinical performance is significant. Emotional intelligence had a fully mediating role between occupational stress and clinical performance among nurses. Married nurses reported to have higher occupational stress and lower emotional intelligence and clinical performance while nurses below 30 years reported high emotional intelligence and clinical performance but low occupational stress. Developing emotional intelligence and providing support and opportunities are crucial strategies to reduce occupational stress among nurses.

Occupational stress and coping strategies of library and information science professionals in Jammu and Kashmir, India

Occupational stress is a physical and psychological condition that can have negative effects. Librarians undergo significant levels of occupational stress. The study assessed levels of occupational stress and different coping strategies in response to it. 37.7 % of library and information science professionals in Jammu and Kashmir have low occupational stress, 32.6 % moderate, and 29.7 % a high level of occupational stress. It was confirmed that these professionals utilize both problem-focused and emotion-focused coping strategies to manage stress. However, the prevalence of emotion-focused coping is more noticeable among them. Role overload, low status, interpersonal problems, lack of respect, and other factors were identified as elements causing occupational stress. Occupational stress and coping strategies displayed a weak yet positive relationship.

Dietary Patterns, Occupational Stressors and Body Composition of Hospital Workers: A Longitudinal Study Comparing before and during the COVID-19 Pandemic.

This longitudinal study aimed to evaluate the association between dietary patterns and the body composition of hospital workers subjected to occupational stressors before and during the COVID-19 pandemic. Data on sociodemographic, occupational, lifestyle, anthropometric, food consumption and occupational stress were collected before and during the COVID-19 pandemic. A total of 218 workers from a private hospital in Santo Antônio de Jesus, Bahia, Brazil were included in the study. After evaluating the normality of the data, parametric or non-parametric tests were used to characterize the sample. Dietary pattern was defined with Exploratory Factor Analysis and Structural Equation Modeling was used to test the desired association. During the pandemic, work per shift increased by 8.2% (p = 0.004) and working hours > 40 h/week increased by 9.2% (p = 0.006). Despite the higher prevalence of low occupational stress (85.8% vs. 72.1%), high stress increased by 13.7% from 2019 to 2020 (p < 0.001) and 30.3% reported a positive mediating effect on the variables of body composition, body mass index (b = 0.478; p < 0.001), waist circumference (b = 0.395; p = 0.001), fat-free mass (b = 0.440; p = 0.001) and fat mass (b = -0.104; p = 0.292). Therefore, a dietary pattern containing high-calorie foods was associated with changes in the body composition of hospital workers, including occupational stressors as mediators of this relationship.

Association between low back pain perception and occupational in hospital nursing professionals.

Low back pain can be defined as pain and/or discomfort between the coastal margins of the lowest rib and the gluteal fold, and it can cause motor dysfunction, loss of productivity, and changes in job function. There is a greater number of nursing professionals in hospital environments, and, regardless of their numerical contingent, they have the highest percentage of absenteeism due to this condition. To evaluate the association between perception of low back pain and occupational stress in hospital nursing professionals. Eleven nurses and 95 practical nurses (n = 106) were evaluated on their perception of low back pain (Visual Analogue Scale) and occupational stress (job stress scale) using the Demand-Control Model. The chi-square test was used to assess associations between categorial variables (p < 0.05). Low back pain was reported by 74% of the study sample (n = 81). Assessment of occupational stress using the Demand-Control Model showed that 54.7% (n = 58) had low psychological demand and 63.2% (n = 67) had high control at work. Active work was observed in 33% (n = 35) and low demand at work in 30.2% (n = 32). There were no significantly associations between the perception of low back pain and the occupational stress domains described by the Demand-Control Model (p = 0.721). Although there was a high prevalence of low back pain in this sample of nursing professionals, it was not associated with occupational stress.

Study on a Bayes evaluation of the working ability of petroleum workers in the Karamay region, Xinjiang, China.

ObjectivesUse Bayes statistical methods to analyze the factors related to the working ability of petroleum workers in China and establish a predictive model for prediction so as to provide a reference for improving the working ability of petroleum workers.Materials and methodsThe data come from the health questionnaire database of petroleum workers in the Karamay region, Xinjiang, China. The database contains the results of a health questionnaire survey conducted with 4,259 petroleum workers. We established an unsupervised Bayesian network, using Node-Force to analyze the dependencies between influencing factors, and established a supervised Bayesian network, using mutual information analysis methods (MI) to influence factors of oil workers’ work ability. We used the Bayesian target interpretation tree model to observe changes in the probability distribution of work ability classification under different conditions of important influencing factors. In addition, we established the Tree Augmented Naïve Bayes (TAN) prediction model to improve work ability, make predictions, and conduct an evaluation.Results(1) The unsupervised Bayesian network shows that there is a direct relationship between shoulder and neck musculoskeletal diseases, anxiety, working age, and work ability, (2) The supervised Bayesian network shows that anxiety, depression, shoulder and neck musculoskeletal diseases (Musculoskeletal Disorders, MSDs), low back musculoskeletal disorders (Musculoskeletal Disorders, MSDs), working years, age, occupational stress, and hypertension are relatively important factors that affect work ability. Other factors have a relative impact on work ability but are less important.ConclusionAnxiety, depression, shoulder and neck MSDs, waist and back MSDs, and length of service are important influencing factors of work ability. The Tree Augmented Naïve Bayes prediction model has general performance in predicting workers’ work ability, and the Bayesian model needs to be deepened in subsequent research and a more appropriate forecasting method should be chosen.

The relationship between occupational stress, mental health and work ability of coal chemical workers in Xinjiang

ObjectiveTo understand the current working ability of coal chemical workers in Xinjiang, and analyze the impact of occupational stress, mental disorders, and their interaction on work ability. To provide a scientific basis for improving the working ability and quality of life of coal chemical workers.MethodsIn this study, a stratified random sampling method was used to conduct a questionnaire survey of 1,400 workers in six coal mining enterprises from June to December 2019. The Effort-Reward Imbalance Questionnaire (ERI), the Symptoms Checklist 90 (SCL-90), and the Work Ability Index Scale (WAI) were used to evaluate the level of occupational stress, mental disorders, and the ability to work as coal chemical workers.ResultsThe results showed that WAI scores had statistically significant differences between gender, age, length of service, shift, education, marital status, and monthly income (P < 0.05). The ability to work and its dimensions were inversely correlated with occupational stress, and mental disorders (P < 0.001). Occupational stress and mental disorders are risk factors affecting the ability to work. Workers with high occupational stress* mental disorders (OR = 10.666, 95% CI: 6.443–17.658) are 10.666 times more likely to be at risk for developing poor work ability than low occupational stress* no mental disorders. Structural equation models show that occupational stress and mental health conditions had a direct impact on work ability, and mental health conditions were the mediators of the relationship between occupational stress and work ability.ConclusionOccupational stress, mental disorders, and their interaction are risk factors affecting the ability of coal chemical workers to work. Occupational stress can indirectly affect the ability to work through mental health conditions.

Occupational stress and addiction potential among psychiatric hospital staff: an analytical study

ABSTRACT Background Employees working in psychiatric hospitals are exposed to high occupational stress (OS) which increases the probability of taking drugs. The present study aims to determine the relationship between OS and addiction potential (AP) among psychiatric hospital staff. Methods A total of 150 staff members of Farabi Hospital in Kermanshah in 2019 were selected using convenience methods. Data collection tools included demographic characteristics questionnaire, Elliott Occupational Stress Questionnaire (OSQ), and Weed et all’s Addiction Potential Scale (APS). Results The 150 employees (59 females and 91 males) with mean age of 39.41 (7.84) were surveyed. The majority of employees, about 116 (77.3%), had low OS. Statistically significant relationships were found between OS plus AP and age group, marital status, educational level, and years of work experience of employees. The mean score of AP had a statistically significant difference between subjects with differences in working hours as well as smoking history. Also, the effect of OS was significant on the level of AP, active AP, and passive AP (all P < .05). Conclusion Considering the effect of OS on the level of AP, it is suggested that targeted interventions are planned and designed to reduce OS among psychiatric hospital staff.

Evaluation of the status, job satisfaction and occupational stress of Chinese nature reserve staff

China is one of the most biodiverse regions of the world. To better preserve its biological resources and the fragile ecosystem, China’s government has established more than 2700 nature reserves, covering approximately 18% of its total land area. While there is a growing body of literature analyzing the effectiveness of nature reserves, little is known about the nature reserve staff who are on the frontlines of wildlife conservation to ensure these areas are effectively protected. This study aims to identify the current status, job satisfaction, and occupation stress of nature reserve staff in China, as well as what factors contribute to the level of satisfaction and stress. We surveyed a total of 286 staff covering 153 nature reserves in 31 provinces of mainland China. The survey results indicate that 63.6% of nature reserve staff were satisfied with their jobs and showed low occupational stress. Nonetheless, they were not satisfied with fringe benefits, payment, promotion opportunities, and operating conditions. There was also a geographic difference in the level of satisfaction and stress. Comparing different positions among nature reserve staff, we found that rangers were more male-dominated, less educated, older and had been exposed to more life-threatening situations than non-rangers. In addition, they were more likely to be contractors instead of formal employees, receive lower pay and spend less time with their families compared to non-rangers. Rangers were generally confident in their professional skills and but less confident in first aid and the use of GIS software. The rangers were less satisfied with their jobs compared to non-rangers, although the difference was not significant. Only about 58% of the nature reserve staff felt that they had received enough training. About 1/3 of the nature reserve staff would like to quit their job. The reasons include low payment and rewards, lack of infrastructure support, no law enforcement capability when encountering illegal activities and living too far from families. Finally, the model results show that more time spent with family, higher income, more training, and more affection for nature significantly contributed to the overall job satisfaction. Factors like the increase in age, more time with family, higher income, more training, and higher confidence in professional skills, were negatively correlated with the stress of nature reserve staff. Our results suggest that to improve the conditions of nature reserve staff and the management of protected areas, governments and managers need to provide enough training and increase income and rewards to recognize the contribution of nature reserve staff, as well as change the hiring mechanism to attract and keep new employees.

Association of occupational stress, period circadian regulator 3 (PER3) gene polymorphism and their interaction with poor sleep quality.

Occupational stress is associated with sleep quality among workers and the human variable number tandem repeat (VNTR) polymorphism of the period circadian regulator 3 (PER3) gene relates to sleep-wake regulation. The main aims of the present study were to examine the effects of PER3 VNTR genotypes, occupational stress, and their interactions on sleep quality. A cross-sectional study was conducted and 729 workers were recruited in Sichuan. Sleep quality were assessed using the Pittsburgh Sleep Quality Index. Occupational stress was measured using the Generic Job Stress Questionnaire. PER3 genotypes were determined with polymerase chain reaction. High and medium occupational stress were linked to a higher risk of poor sleep quality than low levels. Unconditional logistic regression indicated that PER3 genotype was significantly associated with sleep quality, and an increased risk of poor sleep of >1.5-times was observed in those with the allele 5 compared to allele 4. The 5/5 genotype was associated with both sleep latency and sleep duration. Crossover analysis showed an occupational stress×PER3 interaction. Compared to subjects with both low and medium occupational stress and 4/4+4/5 genotype, those with both high occupational stress and 5/5 genotype had a higher risk of poor sleep quality. Stratified logistic analyses found that compared with low and medium occupational stress, high occupational stress increased the risk of poor sleep by more than five-times in 5/5 genotype carriers. Occupational stress and PER3 genotype had both separate and combined effects on poor sleep quality of workers. The results suggest that occupational stress may increase the risk of poor sleep quality through interaction with the PER3 gene polymorphism.

Educators' self-esteem: the effect of perceived occupational stress and the role of organizational support

PurposeThis research investigates the mediation effect of perceived organizational support on the relationship between organization-based self-esteem and perceived occupational stress of teachers.Design/methodology/approachThe present quantitative venture follows a causal research design to unveil the relationship among organization based self-esteem (independent variable), perceived occupational stress (dependent variable) and perceived organizational support (intervening variable). The research surveys 813 educators from nineteen selected distinct areas of Dhaka city; the survey instrument has twenty-six items apart from some general inquires about the respondents. To address the dynamic interplay among these variables, a confirmatory factor analysis (CFA) is conducted within a structural equation modeling (SEM) framework.FindingsTeachers with low self-esteem perceived a high level of occupational stress, whereas teachers who perceived high organizational support feel low occupational stress. Increasing organizational support not only increases organization-based self-esteem but also mediates the relationship between self-esteem and occupational stress.Practical implicationsTeachers' stress is not only an increasing problem over the years but also it was one of the top six most stressful professions. The present study outlines the possible organizational initiatives that can reduce the stresses of the teaching profession.Originality/valueThe findings of the present study square with several theoretical frameworks such as the job demands–resources (JD–R) model and conservation of resources (COR) theory. The results highlight the fact that allowing school teachers to express their ideas and points of view makes them feel esteemed. Likewise, good relations with the school head and getting positive feedback are found to be contributing factors. The teachers feel lesson planning overburdensome and undue office inspections hurt their self-esteem. Any school can increase the self-esteem of the teachers by providing support and training to adjust to changes.

Association of occupational stress with depressive symptoms of workers in a power grid enterprise

Objective To explore the influencing factors of workers' depressive symptoms in a power grid enterprise and the relationship between occupational stress and depressive symptoms. Methods Totally 1 091 employees in a power grid enterprise were studied. The JCQ and ERIQ were used to survey the occupational stress and CES-D was used to investigate depressive symptoms. Multivariate logistic regression was used to analyze the influencing factors of depressive symptoms. Results The main occupational hazards exposed to workers were noise and electromagnetic radiation. Totally 974 workers (89.3%) finished this survey effectively and the morbidity of depressive symptoms was 36.7% among these population. The multivariate logistic regression analyses showed that in JDC model the risk of depressive symptoms among workers with sleep time of 6 to 7 hours or longer than 7 hours was 0.658 (95%CI: 0.481-0.901) and 0.362(95%CI: 0.239-0.550) respectively compared with workers with sleep time less than 6 hours. The workers exposed to visual display terminal had higher risk of depressive symptoms (OR=1.493, 95%CI: 1.118 -1.995) compared with other workers. The medium and high social support were protective factors and the risk of depressive symptoms was 0.594(95%CI: 0.430-0.821) and 0.539(95%CI, 0.342-0.850) respectively compared with workers with low social support. The workers with high JDC occupational stress had higher risk of depressive symptoms (OR=1.667, 95%CI: 1.239-2.242) compared with the workers with low JDC occupational stress. In the ERI model, the risk of depressive symptoms among workers with sleep time of 6 to 7 hours or longer than 7 hours was 0.674(95%CI: 0.490-0.927) and 0.394(95%CI: 0.258-0.601) respectively compared with workers with sleep time less than 6 hours. The workers exposed to visual display terminal had higher risk of depressive symptoms (OR=1.475, 95%CI: 1.100-1.978) compared with other workers. The workers with high overcommitment or high ERI had higher risk of depressive symptoms (OR=1.813 or 2.554, 95% CI: 1.234-2.664 or 1.866-3.495) respectively compared with workers with low overcommitment or low ERI. Conclusions Employees in this power grid enterprise had relatively high morbidity of depressive symptoms. The Enterprise should build a good working environment, strength the social support for employees to reduce occupational stress. The employees should also arrange their work and rest time reasonably, enhance self-regulation ability, and relieve their own work pressure to prevent the occurrence of mental illnesses such as depressive symptoms.

Regional Gray Matter Volume Related to High Occupational Stress in Firefighters.

BackgroundFirefighters inevitably encounter emotionally and physically stressful situations at work. Even firefighters without diagnosed post-traumatic stress disorder receive clinical attention because the nature of the profession exposes them to repetitive trauma and high occupational stress. This study investigated gray matter abnormalities related to high occupational stress in firefighters using voxel-based morphometry (VBM) and surface-based morphometry (SBM).MethodsWe assessed 115 subjects (112 males and 3 females) using magnetic resonance imaging and evaluated occupational stress by the Korean Occupational Stress Scale-26 (KOSS-26). Subjects were classified into highly or lowly stressed groups based on the median value of the KOSS-26.ResultsIn VBM analysis, we found that firefighters with high occupational stress had lower gray matter volume (GMV) in both sides of the insula, the left amygdala, the right medial prefrontal cortex (mPFC), and the anterior cingulate cortex than firefighters with low occupational stress. In SBM analysis based on regions of interest, the GMV of the bilateral insula and right mPFC were also lower in the highly stressed group. Within the highly stressed group, low GMV of the insula was significantly correlated with the length of service (left: r = −0.347, P = 0.009; right: r = −0.333, P = 0.012).ConclusionOur findings suggest that regional GMV abnormalities are related to occupational stress. Regional gray matter abnormalities and related emotional dysregulation may contribute to firefighter susceptibility to burnout.

Регуляторно-личностные факторы надёжности деятельности оперативного персонала энергетических объек

Relevance. The article presents research results regarding personal and regulatory factors influencing the reliability of personnel in power plants. We discuss the possibility of integrating different psychological approaches to assessing functional reliability. We had assumed that including dynamic variables (acute and chronic stress manifestations, “internal cost” of activity) and stable personal factors in the analysis will permit to compare their contribution to psychological stability and reliability. Methods. The main indicators of the study include: personality traits (ITO, Sobchik, 1998); functional components of self-regulation (“SSPM with a reliability scale”, Morosanova, Bondarenko, 2015); occupational stress indices (IDIKS, Leonova, 2006). The number of errors in the cognitive microstructural tests “Attention Span” and “Stimuli Recognition”, S. Sternberg’s model) was assessed as objective parameter of the operators’ reliability. The sample includes 378 employees of power plants (average age 41): 31 people are middle managers (chiefs and their deputies) and 347 are operational and technical personnel (engineers, electricians, controllers). The results indicate that the main psychological predictors of low occupational stress manifestation include: (1) regulatory processes and features (modeling performance conditions and assessing the result); (2) personality traits (high extraversion and emotional lability, moderate anxiety, sensitivity and self-sufficiency). The level of self-regulation determines differences in indicators of performance reliability of the operating personnel (error-free completion of microstructural tests).

Risk and protective factors for burnout among physicians from standardized residency training programs in Shanghai: a cross-sectional study

BackgroundHigh burnout has been reported in physician populations. Although the standardized residency training (SRT) in China includes components that might put residents at a higher risk for burnout, the burnout of Chinese medical residents is unknown. This study aimed to evaluate the prevalence of burnout and the associated risk and protective factors for medical residents in the SRT program in Shanghai, China.MethodsThis study was a prospective cross-sectional design. A random sampling strategy was used to recruit 330 resident physicians from four SRT sites in Shanghai, and 318 completed questionnaires were returned. Respondents completed a self-made questionnaire including demographic and work characteristics, four burnout and wellness-specific surveys. Bivariate analyses and hierarchical multiple regression models were used to analyze factors associated with three sub-scales of burn out separately.ResultsThe overall burnout rate was 71.4%. Low level rate of personal accomplishment (PA) was extremely high at 69.5%. Night shift experience, high occupational stress, and low social support were significant predictors, which explained 49.1% variance of emotional exhaustion (EE) (F = 26.528, P < 0.01). Factors that significantly predicted depersonalization (DP) included male gender, senior residents, night shift experience, high occupational stress, and low psychological empathy, which explained 51.5% variance totally (F = 29.004, P < 0.01). Senior residents, high income, low occupational stress, and high empathy were also significant predictors of decreased personal achievement (PA), which explained 18.4% variance totally (F = 12.897, P < 0.01).ConclusionsThere was a high burnout rate among SRT residents in Shanghai. Occupational stress and several work-related factors were significant and strong risk factors for burnout, while empathy and social support were mild protective factors. Decreased work-related demands and increased access to resources could assist residents in reducing their work stress and improving their well-being.

Effects of Occupational Stress and Circadian CLOCK Gene Polymorphism on Sleep Quality of Oil Workers in Xinjiang, China.

BackgroundThis study investigated the effect of occupational stress and circadian clock gene polymorphism on sleep disorder of oil workers in Xinjiang, China.Material/MethodsWe enrolled 2300 Xinjiang oil workers who had been working for at least 1 year. The Chinese revised version of the Occupational Stress Questionnaire (OSI-R), the Pittsburgh Sleep Quality Index (PSQI), and General Survey Questionnaire were used. A total of 308 subjects were selected for stress hormone measurements and gene polymorphism analysis of the circadian clock genes CLOCK, PER2, and PER3.ResultsThe occupational stress scores were influenced by sex, smoking, marital status, age, and work type. Different work shift groups and different professional title groups had statistically significant sleep disorder incidences (P<0.05). The middle and high occupational stress groups had significantly higher subjective sleep quality, total PSQI scores, daytime dysfunction factor scores, and sleep disorder than in the low occupational stress group (P<0.05). CLOCK gene rs1801260 locus carrying TC genotype (OR=0.412, 95% CI=0.245–0.695), and CLOCK gene rs6850524 locus carrying GC and CC genotypes decreased sleep disorder risk (OR1=0.357, 95% CI1=0.245–0.695; OR2=0.317, 95% CI2=0.128–0.785). The main factors affecting the sleep quality of oil workers were length of service, individual strain capacity, glucocorticoid levels, Per3 gene, and the rs6850524 loci of CLOCK gene.ConclusionsOccupational stress has an adverse effect on the sleep quality of workers. CLOCK gene and Per3 gene may increase risk of sleep disorders.

Analysis of influencing factors of textile workers' occupational stress

Objective: To explore the occupational stress status and influencing factors of workers in a textile factory in Zhejiang Provice. Methods: In October 2018, 505 workers from a textile factory in Zhejiang Province were selected as research objects by convenient sampling method. A total of 505 questionnaires were distributed, 495 of which were effective and the effective recovery rate was 98.0%. Job Content Questionnaire (JCQ) and Effort Reward Imbalance Questionnaire (REI) were used to investigate textile workers' occupational stress and analyze its influencing factors. The differences of the composition ratio of different groups were tested by χ(2) test. The influencing factors such as age, gender and occupation on occupational stress were analyzed by multivariate logistic regression. Results: ERI analysis results showed that the high and low occupational stress accounted for 30.1% and 69.9%, respectively. The differences of occupational stress among workers of different job types and working ages were statistically significant (P<0.05) . The detection rates of high occupational stress of paper workers and spinners were 47.8% (11/23) and 44.8% (30/67) , respectively, higher than other jobs. The detection rate of high occupational stress for workers with more than 5 years of service was 46.4% (13/28) . The results of JCQ analysis showed that there was no statistical significance in the differences of daily working hours and length of service between different gender, education levels, types of work patterns, and occupational stress (P>0.05) . Job types had significant effects on the occupational stress defined by ERI (P<0.05) , the risk of occupational stress was 2.151 times than that of the coiler. Conclusion: There are significant differences in occupational stress risk among workers of different types of work in textile industry, so different measures should be taken to prevent and control occupational stress in different jobs.

Quality of life of Brazilian industrial workers: a review article.

Workers in general have their quality of life affected; however, in the industrial setting, they are exposed to poor and unhealthy conditions in their workplaces and to different occupational hazards depending on their role, sector of activity, and climatic conditions. This study aimed to analyze the quality of life of Brazilian industrial workers. This is an integrative review. The PICo strategy was used to prepare the research question, and each letter represents one component of the question - population (P), workers; interest (I), quality of life; and context (Co), Brazilian industry. The search and selection process was conducted in the Scientific Electronic Library Online (SciELO) and PubMed databases. The search was conducted from August to September 2019, and studies published in the past 10 years were selected. In most workers, work-related QL deficits were identified mainly in the domains of general health and vitality in the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and of social relationships and environment in the World Health Organization Quality of Life short version (WHOQOL-Bref). The factors that represented risks for quality of life included exposure to noise in the workplace, repetitive strain injury/work-related musculoskeletal disorders, occupational low back pain, occupational stress, and work-related fatigue. Few studies assessing quality of life of industrial workers were found. The reviewed studies showed that quality of life deficits are related to vitality, physical functioning, general health, environment, and psychological health of these workers.

Cross-Sectional Survey on the Relationship Between Occupational Stress, Hormone Levels, and the Sleep Quality of Oilfield Workers in Xinjiang, China.

The impact of psychosocial factors on health has received increased attention. This study employed a multi-stage hierarchical cluster sampling method and a cross-sectional survey was conducted from March to August 2017. By studying 2116 oilfield workers based in Karamay, Xinjiang, the relationship between occupational stress, blood hormone levels, and sleep was analyzed. Occupational stress was measured using the internationally accepted Occupational Stress Inventory Revised Edition (OSI-R) questionnaire and sleep disorders were measured using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The study found that the sleep quality of respondents was not high and the incidence of sleep disorders was 36.67%. The higher the level of occupational stress, the higher the incidence of sleep disorders. Irregular shifts can affect sleep quality and individuals with high-level professional titles experience a higher incidence of sleep disorders than those with low-level titles. The total score of the PSQI was different among the low, medium, and high stress groups. The higher the level of stress, the higher the scores of subjective sleep quality, sleep disorder, and daytime dysfunction. The scores of the PSQI, subjective sleep quality, sleep time, sleep disturbance, and daytime dysfunction in the high-stress group were higher than those in the low stress group. A case-control study found that the concentration of glucocorticoids in the sleep disorder positive group was lower than that in the sleep disorder negative group. The results of the regression analysis showed that glucocorticoid is a protective factor for sleep disorders (OR = 0.989, 95% CI: 0.983–0.995), suggesting that the higher the level of glycosaminoglycan, the less likely the subject is to have sleep disorders. For example, in the case of high occupational stress, the interaction between low and moderate occupational stress levels and glucocorticoids is a protective factor for sleep disorders.
