Job strain exposures vs. stress-related workers' compensation claims in Victoria, Australia: developing a public health response to job stress

Sex and Gender Differences in Occupational Hazard Exposures: a Scoping Review of the Recent Literature

PURPOSE OF REVIEW

Comparative research on sex and/or gender differences in occupational hazard exposures is necessary for effective work injury and illness prevention strategies. This scoping review summarizes the peer-reviewed literature from 2009 to 2019 on exposure differences to occupational hazards between men and women, across occupations, and within the same occupation.

RECENT FINDINGS

Fifty-eight studies retrieved from eight databases met our inclusion criteria. Of these, 30 studies were found on physical hazards, 38 studies on psychological/psychosocial hazards, 5 studies on biological hazards, and 17 studies on chemical hazards. The majority of studies reported that men were exposed to noise, vibration, medical radiation, physically demanding work, solar radiation, falls, biomechanical risks, chemical hazards, and blood contamination; while women were exposed to wet work, bullying and discrimination, work stress, and biological agents. Within the same occupations, men were more likely to be exposed to physical hazards, with the exception of women in health care occupations and exposure to prolonged standing. Women compared to men in the same occupations were more likely to experience harassment, while men compared to women in the same occupations reported higher work stress. Men reported more exposure to hazardous chemicals in the same occupations as women. The review suggests that men and women have different exposures to occupational hazards and that these differences are not solely due to a gendered distribution of the labor force by occupation. Findings may inform prevention efforts seeking to reduce gender inequalities in occupational health. Future research is needed to explain the reasons for sex/gender inequality differences in exposures within the same occupation.

Does organizational climate moderate the relationship between job stress and intent to stay?

Purpose

The purpose of this paper is to investigate the moderating influence of organizational climate in the relationship between job stress and intent to stay.

Design/methodology/approach

This study has used a non-probability sampling design for data collection. A semi-structured questionnaire has been prepared and a street survey has been carried out at popular public places in Macau.

Findings

This study shows that stressful employees working in organizations characterized by unsupportive organizational climate had far less desire to stay with the organization than those working in organizations with supportive organizational climate.

Research limitations/implications

Street intercept survey is a technique of convenience sampling. This makes it difficult to generalize the study’s findings to the entire population.

Originality/value

Few studies to date have paid attention to the influence of organizational climate between job stress and intent to stay. The multi-industry context from which the data are collected suggests that the results and findings are useful to managers and practitioners from across a broad range of business sectors.

The impact of workplace factors on filing of workers' compensation claims among nursing home workers

Background

Injuries reported to workers’ compensation (WC) system are often used to estimate incidence of health outcomes and evaluate interventions in musculoskeletal epidemiology studies. However, WC claims represent a relatively small subset of all musculoskeletal disorders among employed individuals, and perhaps not a representative subset. This study determined the influence of workplace and individual factors on filing of workers’ compensation claims by nursing home employees with back pain.

Methods

Surveys were conducted in 18 skilled nursing facilities in four U.S. states. Self-administered questionnaires obtained information on demographic characteristics, working environment, and health behaviors/status. Employees who reported low back pain at least once in four questionnaire surveys were included. WC claims from the same facilities were obtained from the employer’s workers compensation insurer and matched by employee name. The dichotomous dependent variable was filing of back-related worker’s compensation claim. Association with predictors of interest, including pain severity, physical job demand, job strain, social support, schedule control, and safety climate, was assessed using multivariate regression modeling. Individual characteristics were tested as potential confounders.

Results

Pain severity level was significantly associated with filing low-back related claims (odds ratio (OR) = 1.49, 95% CI = 1.18 – 1.87). Higher physical demands at work (OR = 1.07, 95% CI = 1.01 – 1.14) also increased the likelihood of claim filing. Higher job strain (OR = 0.83, 95% CI = 0.73 – 0.94), social support at work (OR = 0.90, 95% CI = 0.82 – 0.99), and education (OR = 0.79, 95% CI = 0.71 – 0.89) decreased the likelihood of claim filing.

Conclusions

The results suggest that the WC system captured the most severe occupational injuries. Workplace factors had additional influence on workers’ decision to file claims, after adjusting for low back pain severity. Education was correlated with worker’s socioeconomic status; its influence on claim filing is difficult to interpret because of the possible mixed effects of working conditions, self-efficacy, and content knowledge.

Job stressors and smoking cessation among Malaysian male employees

BACKGROUND

Job stressors may reduce the likelihood of quitting smoking.

AIMS

To assess the association between job strain, smoking behaviour and smoking cessation among Malaysian male employees involved in a smoking cessation programme.

METHODS

The study was conducted among employees in two major public universities in Malaysia. All staff from both universities received an invitation to participate in this study. At the start of treatment, participants completed a questionnaire on sociodemographic variables, smoking habits and the Malay version of the Job Content Questionnaire (JCQ). The JCQ consists of scales of job control, job demand, supervisor support, co-worker support, job insecurity, job decision latitude and job skill discretion. Behaviour therapy with free nicotine replacement therapy (NRT) was given as treatment for two months. Participants were contacted at 1 week, 3 months and 6 months to determine their smoking status.

RESULTS

One hundred and eighty five staff from both universities responded and voluntarily showed interest in quitting. At three months (OR = 8.96; 95% CI: 1.14-70.76) and six months (OR = 8.9; 95% CI: 1.15-68.65), men with higher co-workers' support demonstrated a higher likelihood of quitting. Smokers in a 'passive job' also demonstrated higher likelihood of quitting compared with those working in the 'low strain' category at six months (OR = 9.92; 95% CI: 1.20-82.68). No meaningful associations were found between other psychosocial job variables and smoking cessation.

CONCLUSIONS

A positive relationship with and support from co-workers are important factors for workplace smoking cessation.

The recognition of occupational diseases attributed to heavy workloads: experiences in Japan, Korea, and Taiwan

OBJECTIVE

Health problems caused by long working hours and work stress have gained growing concerns in Japan, Korea, and Taiwan. In all the three countries, cardiovascular, cerebrovascular, and mental disorders attributed to heavy workloads or stressful work events are considered compensable occupational diseases by workers' compensation systems. This study compared the trends of such cases and correlated the trends with changes in working hours during the period from 1980 to 2010.

METHODS

Data on occupational diseases were obtained from official statistics of the workers' compensation systems. Information on working hours was obtained from official statistics and national surveys of employees.

RESULTS

While occupational cardiovascular, cerebrovascular, and mental disorders attributed to work stress were increasingly compensated in all the three countries, the averaged working hours and the percentage of employees with long working hours had been in decline discordantly.

CONCLUSION

Findings of this study suggested that reducing working hours alone is unlikely to reduce the problems of work stress. There is an urgent need to monitor and regulate a wider range of psychosocial work hazards. Especially, precarious employment and its associated health risks should be targeted for effective prevention of stress-related health problems in the workplace.

Work-related stress and psychosomatic medicine

This article introduces key concepts of work-related stress relevant to the clinical and research fields of psychosomatic medicine. Stress is a term used to describe the body's physiological and/or psychological reaction to circumstances that require behavioral adjustment. According to the Japanese National Survey of Health, the most frequent stressors are work-related problems, followed by health-related and then financial problems. Conceptually, work-related stress includes a variety of conditions, such as overwork, unemployment or job insecurity, and lack of work-family balance. Job stress has been linked to a range of adverse physical and mental health outcomes, such as cardiovascular disease, insomnia, depression, and anxiety. Stressful working conditions can also impact employee well-being indirectly by directly contributing to negative health behaviors or by limiting an individual's ability to make positive changes to lifestyle behaviors, such as smoking and sedentary behavior. Over the past two decades, two major job stress models have dominated the occupational health literature: the job demand-control-support model and the effort-reward imbalance model. In both models, standardized questionnaires have been developed and frequently used to assess job stress. Unemployment has also been reported to be associated with increased mortality and morbidity, such as by cardiovascular disease, stroke, and suicide. During the past two decades, a trend toward more flexible labor markets has emerged in the private and public sectors of developed countries, and temporary employment arrangements have increased. Temporary workers often complain that they are more productive but receive less compensation than permanent workers. A significant body of research reveals that temporary workers have reported chronic work-related stress for years. The Japanese government has urged all employers to implement four approaches to comprehensive mind/body health care for stress management in the workplace: focusing on individuals, utilizing supervisory lines, enlisting company health care staff, and referring to medical resources outside the company. Good communications between occupational health practitioners and physicians in charge in hospitals/clinics help employees with psychosomatic distress to return to work, and it is critical for psychosomatic practitioners and researchers to understand the basic ideas of work-related stress from the viewpoint of occupational health.

Job strain among Malaysian office workers of a multinational company

BACKGROUND

Information on job strain exposure among Malaysian workers in multinational companies is limited.

AIMS

To investigate the prevalence and factors associated with high job strain among office workers of a multinational company in Malaysia.

METHODS

A cross-sectional study was conducted in November 2007 among 470 eligible workers. Respondents self-administered the Job Content Questionnaire downloaded from the company's intranet. A median-split procedure was applied to create four groups according to the Job Demand-Control Model: active, passive, high and low job strain. Logistic regression models were used to investigate the associations between socio-demographic, occupational and psychosocial factors and high job strain.

RESULTS

A total of 356 questionnaires were received (response rate 76%). Twenty-one per cent of respondents were in the high job strain group, 35% were in the passive group, whereas 26% and 17% of workers were in the low strain and active groups, respectively. After controlling for confounders, three factors were found to be associated with high job strain: male workers (adjusted OR 1.94, 95% CI 1.04-3.64), working >48 h per week (adjusted OR 2.51, 95% CI 1.44-4.39) and job insecurity (adjusted OR 1.14, 95% CI 1.02-1.27). One protective factor for high job strain was the scale 'created skill', which is part of skill discretion (adjusted OR 0.70, 95% CI 0.57-0.86).

CONCLUSIONS

About one in five workers in this study experience high job strain. Work improvement measures include reducing long working hours and job insecurity and giving workers the opportunity to learn, use creativity and develop abilities.
