Poor Health but Not Absent

The objective of this study was to examine the prevalence of presenteeism, to develop and test a model of the relationship between workplace factors and presenteeism, and to assess the perceived influence of manager, coworkers, and self on presenteeism. We used survey data collected for 6309 employees from seven different organizations. Nearly 60% of the sample reported presenteeism during a 3-month period. The model was supported, with presenteeism linking workplace factors and health outcomes to productivity, as predicted. The majority of participants (67%) indicated that the primary pressure to attend work while sick came from themselves. A substantial minority (20%) also indicated the manager as a source of pressure. Psychosocial workplace factors are predictive of presenteeism, and efforts to control them, including the use of more effective management, may impact presenteeism rates and the resulting levels of productivity.

Does work-site physical activity improve self-reported psychosocial workplace factors and job satisfaction? A randomized controlled intervention study

To investigate whether a work-site strength-training program has a positive effect on self-reported psychosocial workplace factors and job satisfaction. We conducted a randomized controlled trial among laboratory technicians implementing neck and shoulder exercises for pain relief, with 199 participants in the training group and 228 in the control group. Influence at work, sense of community, time pressure, and job satisfaction were measured with the Copenhagen Psychosocial Questionnaire at baseline and post-intervention after 20 weeks. There was no statistically significant change in any of the four variables in the training group from baseline to follow-up (all p ≥ 0.39). When we used MANOVA to test for between-group effects over time, we did not find any statistically significant result (all p > 0.14). This study does not provide evidence for an effect of a work-site strength-training program on self-reported psychosocial workplace factors and job satisfaction.

Job insecurity, work‐family imbalance, and hostile work environment: Prevalence data from the 2010 National Health Interview Survey

Little nationally representative information on job insecurity, work-family imbalance, and hostile work environments experienced by workers in the US is available. Prevalence rates from the 2010 National Health Interview Survey (NHIS) were calculated for three workplace psychosocial factors (job insecurity, work-family imbalance, bullying/harassment) using SUDAAN to account for the complex NHIS sample design. Data were available for 17,524 adults who worked in the 12 months that preceded the interview. Overall prevalence rates were 31.7% for job insecurity, 16.3% for work-family imbalance, and 7.8% for hostile work environment (being bullied or harassed). The highest prevalence rate of job insecurity was found for construction and extraction occupations. Workers in legal occupations had the highest prevalence rate of work-family imbalance. Workers in protective service occupations had the highest prevalence rate of hostile work environment. We identified demographic characteristics along with industries and occupations with the highest prevalence rates for three adverse workplace psychosocial factors. These data can be used for benchmarking and identification of targets for investigation and intervention activities.

The relationship between immigration and mental health: what is the role of workplace psychosocial factors

To study the relationship between immigration and mental health considering the psychosocial factors in the workplace. Multistage cluster sampling was used (final sample: 7,612 workers). Workers whose country of origin was unknown were excluded from the study (study population: 7,555). The information was collected between 2004 and 2005 using a standardized questionnaire, and interviews were conducted in respondents' homes. The risk of poor mental health according to psychosocial factor, using the native, non-exposed workers as a reference, was calculated using log-binomial models. The prevalence ratio (PR) and confidence intervals (CI 95%) were estimated from crude data and from data adjusted for sex, age, and occupational category. Immigrants who experienced high quantitative demands (PR=1.46; CI 95%:1.34-1.59), high emotional demands (PR=1.42; CI 95%:1.301.56), high demands for hiding emotions (PR=1.35; CI 95%:1.21-1.50), low possibilities for development (PR=1.21; CI 95%:1.09-1.33), low levels of support from coworkers (PR=1.41; CI 95%:1.30-1.53), and low esteem (PR=1.53; CI 95%:1.42-1.66) perceived worse mental health. Equally, the study found that the immigrants with a high influence (PR=1.19; CI 95%:1.09-1.29) and high control over working times (PR=1.25; CI 95%:1.14-1.36) also reported worse mental health. We also found that native workers exposed to these factors also perceived worse mental health than those who were not exposed and that even, at times, they were at greater risk than exposed immigrants. Differences in mental health between exposed and non-exposed wage earners, whether immigrant or native workers, indicate the importance of taking action to reduce psychosocial factors, as this would benefit both native and immigrant workers.

Are there health effects of harassment in the workplace? A gender-sensitive study of the relationships between work and neck pain

The aim of this study was to identify workplace physical and psychosocial risk factors for neck pain among male and female workers and, in particular, to study the relationship between neck pain and intimidation and sexual harassment in the workplace in a representative sample of the Quebec working population. The study sample included 5405 men and 3987 women. In multiple logistic regression analyses, when taking into account individual and other workplace factors, neck pain was significantly associated with intimidation at work among both male (odds ratio (OR) 1.4 (1.01–1.8)) and female workers (OR 1.3 (1.01–1.8)). Among female workers, neck pain was alsosignificantly associated with unwanted sexual attention (OR 1.6 (1.1–2.4)). If confirmed in prospective studies, these results suggest that interventions to prevent harassment in the workplace may help reduce musculoskeletal disorders in the workplace and that workplace programmes to reduce harassment in the workplace should include prevention of sexual harassment. Practitioner Summary: While taking into account relevant personal factors and previously identified workplace physical and psychosocial risk factors, this gender-based study identifies new work exposures associated with neck pain that have not previously been studied, including unwanted sexual attention, intimidation and difficult or tense situations with the public.

Predictors of 1-year outcomes of major depressive disorder among individuals with a lifetime diagnosis: a population-based study

Examining predictors of the outcomes of major depressive disorder (MDD) is important for clinical practice and population health. There are few population-based longitudinal studies on this topic. The objectives of this study were to (1) estimate the proportions of persistent and recurrent MDD among those with MDD over 1 year, and (2) identify demographic, socio-economic, workplace psychosocial and clinical factors associated with the outcomes. From a population-based longitudinal study of the working population, participants with a lifetime diagnosis of MDD were selected (n=834). They were classified into two groups: those with and those without current MDD. The proportions of 1-year persistence and recurrence of MDD were estimated. MDD was assessed by the World Health Organization (WHO) Composite International Diagnostic Interview, CIDI-Auto 2.1, by telephone. The proportions of persistent and recurrent MDD in 1 year were 38.5% [95% confidence interval (CI) 31.1-46.5] and 13.3% (95% CI 10.2-17.1) respectively. Long working hours, negative thinking and having co-morbid social phobia were predictive of persistence of MDD. Perceived work-family conflict, the severity of a major depressive episode and symptoms of depressed mood were significantly associated with the recurrence of MDD. Clinical and psychosocial factors are important in the prognosis of MDD. The factors associated with persistence and recurrence of MDD may be different. More large longitudinal studies on this topic are needed so that clinicians may predict potential outcomes based on the clinical profile and provide interventions accordingly. They may also take clinical action to change relevant psychosocial factors to minimize the chance of persistence and/or recurrence of MDD.

Workplace Characteristics, Depression, and Health-Related Presenteeism in a General Population Sample

To investigate the relationships between workplace psychosocial factors, work/family conflicts, depression, and health-related presenteeism in a sample of employees who were randomly selected from the communities. A cross-sectional study of 4032 employees representative of the working population aged 25 to 64 years in Alberta, Canada. Data about workplace characteristics, depression, and health-related presenteeism were collected through telephone. In the participants, 47.3% and 42.9% reported some degree of impaired job performance in completing work and avoiding distraction, respectively. Major depression is the strongest factor associated with avoiding distraction. Job strain and effort-reward imbalance seemed to affect job performance through severity of depression but not major depression. Negative work environment may directly and indirectly affect job performance. Workplace health promotion activities should target organizational factors such as job strain and effort-reward imbalance and work/family conflicts so as to reduce the risk of depression and the direct and indirect effects of these risk factors and depression on productivity.

Occupational Stress is Associated with Impaired Work Ability and Reduced Quality of Life in Patients with Chronic Kidney Failure

About 300,000 patients in the United States with Chronic Kidney Failure (CKF) are of working age, but up to 70% lose their job within the first year of renal replacement therapy .No study has examined how work ability and perceived health are influenced by the subjects' adjustment to their job. We assessed the association of occupational stress (Effort-Reward Imbalance, ERI),work ability (WAI) and health-related quality of life (QoL) in hemodialysis. 40 employed hemodialysis patients completed a self-administered questionnaire. Associations between ERI, short Form 12 (sF-12), short Form - 6 Dimensions (sF-6D), Kidney Disease QOL- 36 (KDQOL-36) and WAI were tested with partial Spearman's correlation adjusted for age, income, and comorbidity burden. Study subjects were mainly low-income (82%), african-american (73%), men (75%); 16 were manual laborers and 9 worked in the industrial sector. Study subjects reported low levels of Occupational Stress: ERI scores indicated an imbalance between Job Efforts and Rewards in only 3 subjects. Nevertheless, ERI scores were inversely and strongly associated with WAI (rho=-0.41, p<0.012) and all QoL scales even after adjustment for known confounders. Our study suggests that psychosocial workplace factors may play a substantial role in modulating patients' health perception and ability to continue working. The causal relationship between Occupational stress, perceived health, and work ability should be further investigated. Occupational Health professionals and nephrologists should closely collaborate to meet the needs of occupationally active hemodialysis patients.

Effect of psychosocial factors on low back pain in industrial workers

To test the hypothesis that workplace psychosocial factors such as demand, control, support, job satisfaction and job appreciation can predict the future onset of disabling low back pain (LBP). The present study involved a prospective cohort of 4500 Iranian industrial workers. Data were gathered by means of a self-reported questionnaire about LBP, as well as working life exposure, lifestyle factors, social exposures, co-morbidity, life events and psychosomatic complaints in 2004. All new episodes of disabling LBP resulting in medically certified sick leave during the 1-year follow-up registered by occupational health clinic inside the factory. The participation rate was good (85%). A total of 744 subjects reported current LBP (point prevalence cases). A total of 52 (<2%) new episodes of disabling LBP were observed during the 1-year follow-up (incident cases). Male employees reported higher demands, lower control and lower support than female employees. Employees with high demands, low control, job strain, low job satisfaction and low job appreciation showed increased odds ratios, and these results were statistically significant. Few prospective studies in this field have been published, but all of them are related to industrialized countries. This prospective study suggests the aetiological role of job strain for LBP. The findings of this study indicate a substantial potential for disease prevention and health promotion at the workplace.

Piecework, musculoskeletal pain and the impact of workplace psychosocial factors

To investigate the impact of piecework on musculoskeletal pain and general health, and the influence of perceived workplace psychosocial factors on any such associations, in a general UK population. A questionnaire was mailed to an age-stratified random sample of 10 000 adults aged 18-75 in North Staffordshire, UK. Respondents reporting a current main job were asked if this job was paid by a piecework system. Health measures were (i) number of pain areas according to a body manikin and (ii) general health (SF-12v2). Other measures included questions on occupational history and psychosocial aspects of the work environment. The adjusted response was 54%. A total of 1193 respondents reported a current main job, of whom 201 (17%) reported piecework. Pieceworkers were more likely to be older (P < 0.05), male (P < 0.001) and in lower socioeconomic groups (P < 0.001) than non-pieceworkers. Piecework was associated with perceptions of a poor psychosocial working environment, more pain areas (P < 0.05), more elbow (P < 0.01), forearm (P < 0.001) and hand pain (P < 0.05), and a lower physical health score (SF-12v2; P < 0.01), but no difference in mental health score (P = 0.60), compared with non-pieceworkers. After controlling for psychosocial factors, and socioeconomic group, the associations between piecework and pain areas, or physical health, were no longer statistically significant. These results show that piecework was associated with poorer self-reported general physical health and more areas of pain, which may be attributed to low socioeconomic group, and workplace perceptions of little job control, high physical demand and little supervisor support.

Prevalence of complaints of arm, neck and shoulder among computer office workers and psychometric evaluation of a risk factor questionnaire

BackgroundComplaints of Arm Neck and Shoulder (CANS) represent a wide range of complaints, which can differ in severity from mild, periodic symptoms to severe, chronic and debilitating conditions. They are thought to be associated with both physical and psychosocial risk factors. The measurement and identification of the various risk factors for these complaints is an important step towards recognizing (a) high risk subgroups that are relevant in profiling CANS; and (b) also for developing targeted and effective intervention plans for treatment. The purpose of the present study was to investigate the prevalence of CANS in a Dutch population of computer workers and to develop a questionnaire aimed at measuring workplace physical and psychosocial risk factors for the presence of these complaints.MethodsTo examine potential workplace risk factors for the presence of CANS, the Maastricht Upper Extremity Questionnaire (MUEQ), a structured questionnaire, was developed and tested among 264 computer office workers of a branch office of the national social security institution in the Netherlands. The MUEQ holds 95 items covering demographic characteristics, in addition to seven main domains assessing potential risk factors with regard to (1) work station, (2) posture during work, (3) quality of break time, (4) job demands, (5) job control, and (6) social support. The MUEQ further contained some additional questions about the quality of the work environment and the presence of complaints in the neck, shoulder, upper and lower arm, elbow, hand and wrist. The prevalence rates of CANS in the past year were computed. Further, we investigated the psychometric properties of the MUEQ (i.e. factor structure and reliability).ResultsThe one-year prevalence rate of CANS indicated that 54% of the respondents reported at least one complaint in the arm, neck and/or shoulder. The highest prevalence rates were found for neck and shoulder symptoms (33% and 31% respectively), followed by hand and upper arm complaints (11% to 12%) and elbow, lower arm and wrist complaints (6% to 7%). The psychometric properties of the MUEQ were assessed using exploratory factor analysis which resulted in the identification of 12 factors. The calculation of internal consistency and cross validation provided evidence of reliability and lack of redundancy of items.ConclusionNeck and shoulder complaints are more frequently reported among Dutch computer workers than arm, elbow and hand complaints. The results further indicate that the MUEQ has satisfactory reliability and internal consistency when used to document CANS among computer workers in the Netherlands.

Symptomatology of recurrent low back pain in nursing and administrative professions.

The aim of the present study was to explore if (a) recurrent low back pain (LBP) has different symptomatologies in cases from occupations with predominantly sitting postures compared to cases from occupations involving dynamic postures and frequent lifting and (b) if in the two occupational groups, different factors were associated with the presence of recurrent LBP. Hundred and eleven female subjects aged between 45 and 62 years with a long-standing occupation either in administrative or nursing professions, with and without recurrent LBP were examined. An extensive evaluation of six areas of interest (pain and disability, clinical examination, functional tests, MR examination, physical and psychosocial workplace factors) was performed. The variables from the six areas of interest were analyzed for their potential to discriminate between the four groups of subjects (administrative worker and nurses with and without recurrent LBP) by canonical discriminant analysis. As expected, the self-evaluation of physical and psychosocial workplace factors showed significant differences between the two occupational groups, which holds true for cases as well as for controls (P < 0.01). The functional tests revealed a tendency for rather good capacity in nurses with LBP and a decreased capacity in administrative personnel with LBP (P = 0.049). Neither self completed pain and disability questionnaires nor clinical examination or MR imaging revealed any significant difference between LBP cases from sedentary and non-sedentary occupations. When comparing LBP cases and controls within the two occupational groups, the functional tests revealed significant differences (P = 0.0001) yet only in administrative personnel. The clinical examination on the other hand only discriminated between LBP cases and controls in the nurses group (P < 0.0001). Neither MRI imaging nor self reported physical and psychosocial workplace factors discriminated between LBP cases and controls from both occupational groups. Although we used a battery of tests that have broad application in clinical and epidemiological studies of LBP, a clear difference in the pattern of symptoms between LBP cases from nursing and hospital administration personnel could not be ascertained. We conclude that there is no evidence for different mechanisms leading to non-specific, recurrent LBP in the two occupations, and thus no generalizable recommendations for the prevention and therapy of non-specific LBP in the two professions can be given.

Psychological Benefits of Indoor Plants in Workplaces: Putting Experimental Results into Context

Laboratory experiments and quasi-experimental field studies have documented beneficial effects of indoor plants on outcomes such as psychophysiological stress, task performance, and symptoms of ill health. Such studies have taken an interest in the value of indoor plants in work settings, but they typically have not considered how the effects of plants might compare with effects of other workplace characteristics. The present study makes an initial attempt to situate the potential benefits of indoor plants in a broader workplace context. With cross-sectional survey data from 385 Norwegian office workers, we used hierarchical regression analyses to estimate the associations that plants and several often-studied workplace factors have with perceived stress, sick leave, and productivity. Other variables included in our models were gender, age, physical workplace factors (e.g., noise, temperature, lighting, air quality), and psychosocial workplace factors (demands, control, social support). After controlling for these variables, the number of indoor plants proximal to a worker's desk had small but statistically reliable associations with sick leave and productivity. Although small, such associations can have substantial practical significance given aggregation over the large number of office workers over time.

Randomized Controlled Trial of Workplace-based Rehabilitation for Work-related Rotator Cuff Disorder

Return to work following an occupational injury is a multifactoral process although many traditional clinic-based rehabilitation programs do not appreciate the importance of workplace factors. A randomized controlled trial was conducted to investigate the effect of workplace-based rehabilitation program on the return to work outcome of work-related rotator cuff disorder, which is based on the therapeutic use of actual work facilities and work environment. A total of 103 workers were recruited and randomly assigned into Clinic-based Work Hardening (CWH) or Workplace-based Work Hardening (WWH) groups. The CWH group were given traditional generic work hardening training while WWH group received workplace-based work hardening training with rehabilitative principles of athletic rotator cuff pathology, biomechanics and specific job activities. After four weeks, a higher return to work rate was obtained in WWH group compared to CWH group (71.4% vs. 37%, p < 0.01). A statistically significant difference (p < 0.05) was also noted in lowering of self-reported shoulder problems and functional work capabilities in the WWH group versus the CWH group. Workplace-based rehabilitation program appeared to be more effective in facilitating the return to work process of the injured worker as assessed immediately following intervention. In particular this approached was associated with many of the psychosocial workplace factors related to separation from the work routine. The influence of peer group and/or employer could be minimized. This initial attempt with rotator cuff injuries appears promising however long-term outcome needs to be determined.

Risk factors for more severe regional musculoskeletal symptoms: A two‐year prospective study of a general working population

To quantify the relative contribution of work-related physical and psychosocial factors, individual factors, and health-related factors to the development of more severe musculoskeletal pain in the neck and upper limbs and the back and lower limbs. In this cohort study of 5,604 workers from industrial and service companies, we collected information on work-related physical and psychosocial exposures and on individual and health-related factors. Questionnaires were completed at baseline by 4,006 participants (71.5%) and after 24 months by 3,276 (82%). At followup, participants with no or minor pain were included in Cox regression analyses to determine which factors predicted more severe regional pain. Of the 4,006 baseline respondents, only 7.7% were free of regional pain. A total of 1,513 participants were free of severe pain at baseline and completed the 24-month followup. Highly repetitive work predicted arm pain, heavy lifting and prolonged standing predicted low back pain, and heavy pushing or pulling predicted lower limb pain. Low job satisfaction predicted neck/shoulder pain and lower limb pain, whereas other psychosocial work place factors were only of marginal importance. High levels of fear avoidance were associated with arm pain and lower limb pain. A high body mass index was highly associated with lower limb pain. Very few workers are totally free of pain in musculoskeletal regions, and we question the concept of incidence of musculoskeletal pain. The transition from no or minor pain to more severe pain was influenced by physical and psychosocial work place factors together with individual and health-related factors.

Secondary prevention of work-related upper extremity disorders: recommendations from the annapolis conference

Efforts to improve the secondary prevention of work-related upper extremity (WRUE) symptoms continue to present a challenge. As with many occupational musculoskeletal pain disorders no single, direct cause-effect relationship exists among specific exposures, pathologic processes, and symptoms. The field has yet to create truly effective and efficient interventions for these problems that are based on current epidemiological and clinical knowledge. A working conference was held in Annapolis, Maryland on September 23rd and 24th, 2005 with leaders in research and application related to upper extremity disorders to address this challenge. The intent of the meeting was to review "state of the art" evidence in epidemiology and intervention research in order to develop suggestions regarding next steps in intervention research and application. On day 2 a number of stakeholders were present to discuss what they perceived as the missing pieces in both epidemiological research and applied intervention research in order to generate more effective workplace interventions. The papers in this series of the Journal of Occupational Rehabilitation indicate that scientifically sound progress has been made over the past decade in identifying ergonomic, workplace psychosocial, and individual factors in both the etiology and exacerbation of these symptoms/disorders. However, there is a gap between this knowledge and the development and practical implementation of comprehensive interventions for these problems. The conference also highlighted the paucity of economic analyses of the impact of these disorders as well as the economic study of the impact of intervention. Approaches for such evaluations were presented and are included in this special section of the journal. This series of papers and the summary of the invited group's discussions provided in this paper clearly emphasize the need for innovative ways to think about these problems and specific research topics that can help translate this knowledge into effective secondary prevention efforts.
