- STUDY DESIGN: Four-year prospective cohort study. OBJECTIVE: To find the incidence of sick leave because of neck and shoulder pain (NSP) in industrial workers, and its association with work and lifestyle risk factors. SUMMARY OF BACKGROUND DATA: Longitudinal studies to investigate NSP incidence and risk factors are rare, and even fewer have been conducted in middle- and low-income countries. METHODS: After inviting all full-time employees of an Iranian car manufacturing company with 18,031 employees to participate in a baseline study, they were followed for 4 years. New episodes of sick leave because of NSP have been calculated based on sickness absence registration between the years 2003 and 2007. The incidence was compared for participants and nonparticipants. The association between sick leave, physical, and psychosocial risk factors at work, and previous self-reported NSP, was calculated for the remaining population of baseline participants (12,184 employees) during a 4-year follow-up. RESULTS: During a 4-year follow-up of study subjects for the remaining participants of the baseline study, the incidence of sick leave was 0.8% (98 sick leave cases in 12,184 employees). For nonparticipants this incidence was 4.2% (130 cases in 3127 employees). In the final regression model for sick leave cases, the remaining factors for potential physical risk factors were repetitive work and sitting positions at work; for psychosocial factors unattractive work was the only significant remaining factor. CONCLUSION: The incidence of NSP based on sick leave is definitely very low compared with previous studies in high-income countries. This incidence varies between participants and nonparticipants. Risk factors for sick leave differ from risk factors for self-reported pain. A young population, job security, the insurance system, different health behaviors, and healthy worker bias, are all factors that may affect the results, and sick-leave as an outcome must be interpreted with more caution in middle- and low-income countries.

- Background Work-related musculoskeletal disorders (MSDs) of the upper extremities are a major problem globally, though most relevant studies have been reported from high income countries. Aims and Methods The prevalence of neck and shoulder pain and its association with work-related physical and psychosocial factors and life style was determined by a cross-sectional survey using the Nordic Musculoskeletal Questionnaire (NMQ) in the largest Iranian car manufacturing company, with more than 18,000 employees. Results A total of 14,384 (79.8%) of all employees completed the questionnaire. Depending on the questions used to measure neck and shoulder symptoms, the prevalence varied widely (from 20.5% to 3.9%). In the multiple logistic regression model, limited to employees with at least I year of work experience, risk indicators for disabling pain of the neck and/or shoulder that remained for male were: duration of employment, high visual demands, repetitive work, sitting position at work, awkward working position, no regular exercise, monotonous work, lack of encouraging organizational culture, and anxiety concerning change. For female repetitive work, sitting position at work and no support if there is trouble at work were the only remaining factors. Conclusions The study confirms the effects of physical and psychosocial factors on neck and shoulder symptoms among automobile manufacturing workers in a low to middle income country in spite of the relative youth and job insecurity of the population.

Tidskriftsartikel (refereegranskat)abstract
- Background Musculoskeletal disorders (MSDs) are a major health problem in the world. Self-reported questionnaires are a known method for estimating the prevalence of MSDs among the population. One of the studies concerning MSDs and their relation to work-related physical and psychosocial factors, as well as non-work-related factors, is the MUSIC-Norrtalje study in Sweden. In this study, the research group developed a questionnaire, which has been validated during its development process and is now considered a well-known instrument. The aim of this study is to validate the Persian version of this questionnaire. Methods The first step was to establish two expert panel groups in Iran and Sweden. The Focus Group Discussion (FGD) method was used to detect questionnaire face and content validity. To detect questionnaire reliability, we used the test-retest method. Results Except for two items, all other questions that respondents had problems with in the focus group (20 of 297), had unclear translations; the ambiguity was related to the stem of the questions and the predicted answers were clear for the participants. The concepts of 'household/spare time' and 'physical activity in the workplace' were not understood by the participants of FGD; this has been solved by adding further descriptions to these phrases in the translation. In the test-retest study, the reliability coefficient was relatively high in most items (only 5 items out of 297 had an ICC or kappa below 0.7). Conclusion The findings from the present study provide evidence that the Persian version of the MUSIC questionnaire is a reliable and valid instrument.

- The influence of potential prognostic factors (occupant- and crash-related factors, initial neck pain intensity and headache, whiplash injury severity, helplessness, locus of control, socioeconomic status) on neck pain intensity (VAS), disability (DRI), anxiety and depression (HADS) was estimated in a cohort of 3704 subjects with whiplash injury following a motor vehicle crash. Questionnaires were administered (baseline, 1-, 6-, 12-, 24-month follow-ups). VAS was trichotomized; "low" (0-30), "moderate" (31-54), "severe" (55-100). A cumulative logit model with a proportional odds assumption was applied. Results regarding depression differed somewhat from the other outcomes. Overall, initial neck pain intensity was an important prognostic factor, but acted also as an evident effect modifier. Females had slightly increased odds for all outcomes but depression, for which no gender differences were shown. Injury severity was associated with all outcomes, but was most pronounced regarding disability among those who perceived numbness/pain in arms/hands and also had severe initial neck pain (proportional odds ratio [OR] 6.5; 95% confidence interval [CI] 2.5-17.0). Initial headache influenced all outcomes. Income was not related to any of the outcomes, whereas a lower level of education was associated with all outcomes but depression. Locus of control was not a factor of importance. In contrast, helplessness was related to all outcomes, but was most pronounced regarding neck pain intensity and depression for subjects with severe initial neck pain (OR 4.8; 95% CI 2.9-7.8; OR 6.6; 95% CI 2.6-17.0). Associations seem to be established early, and then to be relatively constant over time.

Tidskriftsartikel (refereegranskat)abstract
- This study is a prospective multicentre cohort study entitled Work and Health in the Processing and Engineering Industries, the AHA Study (AHA is the Swedish abbreviation for the study). Four large workplaces in Sweden participated during the years from 2000 to 2003. The present report has two objectives: (1) to present a comprehensive occupational health intervention programme and (2) to evaluate this programme with a focus on lifestyle (smoking and exercise), health related quality of life (HRQoL) and sick leave. Interventions were provided on an individual and group level, including evidence-based methods for four health/focus areas (individual level) and a group intervention based on a survey-feedback methodology. The analyses in this report were exclusively employed at an organizational level. The proportion of smokers decreased at three companies and the course of the HRQoL was advantageous at two of the companies as compared to a gainfully employed reference group. A significant decrease in sick leave was revealed at one company, whereas a break in an ascending sick-leave trend appeared at a second company as compared to their respective corporate groups. This comprehensive workplace intervention programme appears to have had positive effects on smoking habits, HRQoL and sick leave.

A thesis on fire : Studies of work engagement, Type A behavior and burnout
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall address of the present thesis is the relationship between being ‘on fire’ and burning out. More specifically, the thesis focused largely on two representations of involvement in work (work engagement and Type A behavior) and their respective relationships to burnout. Another pervasive theme was construct validity in assessing burnout and work engagement. These themes were addressed in four empirical studies, conducted in a sample of health-care workers (Study I) and a sample of information communication technology consultants (Studies II, III, and IV). Study I aimed to extend the previously preliminary support for the construct validity of the Swedish version of the Maslach Burnout Inventory (MBI). The objective of Study II was the discriminant validity of the Utrecht Work engagement Scale (UWES) against the theoretically adjacent constructs job involvement and organizational commitment. Another objective was the translation and evaluation of a Swedish version of the UWES. In Study III, the aim was to investigate (cross-sectional) association between Type A behavior, work engagement and burnout. Study III had two foci: 1) whether Type A behavior interacts with job factors to affect burnout and work engagement, and 2) the associations between the main components of Type A behavior (achievement-striving and irritability/impatience) and burnout as well as work engagement. Study IV concerned the longitudinal relationships between Type A behavior and burnout, and between work engagement and burnout. The results presented in this dissertation supported the construct validity of Swedish versions of the MBI and the UWES. It was further indicated that emotional exhaustion and depersonalization (or cynicism) constitute the core aspects of burnout, and that work engagement was more prominently associated with lack of health complaints than job involvement and organizational commitment. Type A behavior was found to be associated with burnout and work engagement in cross-sectional data, however different aspects of Type A behavior appeared to have somewhat different association with burnout and work engagement respectively. The achievement-striving aspect of Type A behavior was related primarily to work engagement, whereas irritability was associated with less engagement and more burnout complaints. No indications of an interaction between Type A behavior and job stress were found. The most important finding of Study IV was that change in Type A behavior was unrelated to change in burnout across time (one-year interval). Furthermore, Study IV supported the notion that work engagement and burnout are bipolar opposites and constitute a work well-being continuum. To conclude, the present thesis suggests that burnout should be viewed as an erosion of intrinsic, affective engagement in work occurring when intrinsic motivation is frustrated by job stress. To avoid conceptual confusion, burnout should be distinguished form exhaustion syndrome however it should be acknowledged that burnout may have negative impact on health. The present study indicated that Type A behavior is unrelated to the specific burnout reaction, a finding that needs to be replicated before generalizability can be assumed. However, it was assumed that Type A behavior represents an instrumental approach to work, further corroborating that burnout is a specific construct referring to the draining of a specific energetic and affective state. This does not imply that Type A behavior is unrelated to health deterioration – most plausibly, Type A behavior generates exhaustion and fatigue from over-exertion of energy. Both research and practice would benefit from exploring how work engagement may best be enhanced using job redesign.

- Aim 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). Methods 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. Results 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. Conclusions 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.

Tidskriftsartikel (refereegranskat)abstract
- Study Design: Prospective cohort study with 18-month follow-up.Objective: To investigate if long-term sick listed persons' own predictions of their future return to work (RTW) have an impact on their RTW when controlling for other established factors.Method: Postal questionnaires at baseline were sent to persons who had been on sick leave for more than 90 days, and were employed in five municipalities and four county councils in Sweden. A follow-up regarding their RTW was performed 18 months later.Results: After 18 months 135 out of 508 persons (27%) had returned to work, full or part-time. In a multivariate logistic regression, the sick listed persons' own prediction of their RTW proved to be highly significant (OR=8.28, 95% CI: 3.31-20.69). Only six out of 132 persons with a negative view of their RTW did return to wok. Other predictive factors that were found for RTW were: being on sick leave for a period of less than 1 year (OR=2.09, 95% CI: 1.19-3.67), having less pain than persons in the quartile with most pain (OR=2.65, 95% CI: 1.21-5.81), perceiving that one was welcome back to work (OR=1.98, 95% CI: 1.10-3.58), and being under 55 years of age (OR=2.37, 95% CI: 1.07-5.23 for age between 45 and 54 years and the same trend for age below 45 years OR=1.85, 95% CI: 0.82-4.20).Conclusion: Persons with a positive prediction should get help to realise their potential for RTW. Offering traditional rehabilitation measures to a person with a negative prediction of his/her RTW, could be a waste of resources if done ahead of improving self-confidence and view of what is possible. The problems in this group might decrease or be easier to handle if decisions about the future are taken within a year.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: The aim was to identify psychosocial factors at work that promote positive changes in employee health and factors that prevent negative changes in employee health. METHOD:: This study is part of a large longitudinal study and includes 1212 employees. Data for psychosocial work factors and self rated health was collected in 2000 and 2003. A modified Poisson regression was used to find factors of relevance for positive and negative changes in health. RESULTS:: A negative change in leadership, organizational commitment and reporting job strain increased the risk for negative change in health. Improved leadership and social climate increased the chance for positive changes in health. CONCLUSION:: By improving psychosocial factors at work, it is possible to promote employee health as well as prevent employee ill-health.
