Prognostic factors for musculoskeletal sickness absence and return to work among welders and metal workers

OBJECTIVES: To analyse factors that determine the occurrence of sickness absence due to musculoskeletal problems and the time it takes to return to work. METHODS: A longitudinal study with two year follow up was conducted among 283 male welders and metal workers. The survey started with a standardised interview on the occurrence of musculoskeletal complaints. 61 (22%) workers were lost to follow up. Data on sickness absence among 222 workers during the follow up were collected from absence records and self reports. Regression analysis based on proportional hazards models was applied to identify risk factors for the occurrence and duration of sickness absence due to various musculoskeletal complaints. RESULTS: During the follow up 51% of the workers attributed at least one period of sickness absence to musculoskeletal complaints which accounted for 44% of all work days lost. A history of back pain was not associated with sickness absence for back pain, partly because subjects with back pain were more likely to be lost to follow up. Neck or shoulder pain and pain of the upper extremities contributed significantly to neck or shoulder absence (relative risk (RR) 3.35; 95% confidence interval (95% CI) 1.73 to 6.47) and to upper extremities absence (RR 2.29; 95% CI 1.17 to 4.46), respectively. Company and job title were also significant predictors for sickness absence due to these musculoskeletal complaints. Absence with musculoskeletal complaints was not associated with age, height, body mass index, smoking, and duration of employment. Return to work after neck or shoulder absence was worse among metal workers than welders (RR 2.12; 95% CI 1.08 to 4.17). Return to work after lower extremities absence was strongly influenced by visiting a physician (RR 11.31; 95% CI 2.94 to 43.46) and by musculoskeletal comorbidity (RR 2.81; 95% CI 1.18 to 6.73). CONCLUSIONS: Complaints of the neck or shoulder and upper extremities in the 12 months before the study were associated with sickness absence for these complaints during the follow up. Workers with absence due to pain from back, neck or shoulder, upper extremities, or lower extremities were at higher risk of subsequent sickness absence in the next year.

 

     

Influence of change in psychosocial work characteristics on sickness absence: The Whitehall II Study

OBJECTIVES: To study the influence of change in self perceived psychosocial work characteristics on subsequent rates of sickness absence. METHODS: Prospective cohort study of British civil service employees. Job control, job demands, and work social supports were measured in 1985/88 and in 1991/93. Analyses included 3817 British civil servants with sickness absence records at baseline (1985-89) and for two follow up periods, early (1994-95) and later follow up (1996-98). RESULTS: Change in work characteristics predicted subsequent incidence of long spells of sickness absence (>7 days) in the early follow up period after adjustment for covariates including baseline work characteristics, health status, and sickness absence. Adjusted rate ratios were 1.23 (95% CI 1.03 to 1.46) for decreased compared with stable decision latitude; 1.17 (95% CI 1.01 to 1.36) for increased compared with stable job demands and 0.79 (95% CI 0.67 to 0.93) for increased compared with stable work social support. These associations were also seen in a sub-sample who did not change employment grade. In the later follow up period, associations between work change and long spells of sickness absence were similar for decision latitude, less pronounced for job demands, and no longer apparent for social supports. Changes in work characteristics were not associated with subsequent short spells of sickness absence (相似文献   

Psychosocial work factors and long sickness absence in Europe

Abstract

Background: Studies exploring a wide range of psychosocial work factors separately and together in association with long sickness absence are still lacking.

Objectives: The objective of this study was to explore the associations between psychosocial work factors measured following a comprehensive instrument (Copenhagen psychosocial questionnaire, COPSOQ) and long sickness absence (>7 days/year) in European employees of 34 countries. An additional objective was to study the differences in these associations according to gender and countries.

Methods: The study population consisted of 16?120 male and 16?588 female employees from the 2010 European working conditions survey. Twenty-five psychosocial work factors were explored. Statistical analysis was performed using multilevel logistic regression models and interaction testing.

Results: When studied together in the same model, factors related to job demands (quantitative demands and demands for hiding emotions), possibilities for development, social relationships (role conflicts, quality of leadership, social support, and sense of community), workplace violence (physical violence, bullying, and discrimination), shift work, and job promotion were associated with long sickness absence. Almost no difference was observed according to gender and country.

Conclusions: Comprehensive prevention policies oriented to psychosocial work factors may be useful to prevent long sickness absence at European level.     

Identifying workers at risk of sickness absence by questionnaire

BACKGROUND: Sickness absence is an important economic problem, because of high costs and lost productivity. Determining factors associated with increased risk of sickness absence may lead to the development of preventive measures. AIMS: To determine whether self-report questionnaires can identify those employees at risk of sickness absence METHODS: Prospective study of 238 healthy administrative workers. Participants completed a questionnaire proven to be valid and consistent. The questionnaire consisted of 116 items about health, work and working conditions. Sickness absence was followed-up for a period of 1 year. RESULTS: The questionnaires of 191 workers (80%) were suitable for analysis. The number of reported health complaints was significantly (P < 0.01) associated with sickness absence (OR 2.18; 95% CI 1.32-3.61). Concentration problems were correlated with more frequent absences, and both nervous complaints and coping problems with longer duration. Age (OR 0.96; 95% CI 0.93-0.99; P = 0.02) and job insecurity (OR 0.68; 95% CI 0.47-0.98; P = 0.04) were negatively associated with sickness absence. Psychosocial and physical work factors were not associated with sickness absence. CONCLUSIONS: Questionnaires on health and work can identify employees at future risk of sickness absence. Workers who report multiple health complaints, especially concentration problems, nervous complaints or coping problems, may be at increased risk of sickness absence.

Predicting the long term course of low back pain and its consequences for sickness absence and associated work disability

Background

Low back pain is characterised by a dynamic pattern of episodes and recovery but little is known about the long term course of back pain due to lack of cohort studies with sufficiently long follow up periods.

Methods

A cohort of 523 workers in nursing homes and homes for the elderly was followed for two years. Physical load was measured by observations at the workplace. Psychosocial factors at work, individual characteristics, and low back pain were determined by questionnaire once a year. The effect of work load on low back pain and the transition of low back pain into sickness absence was calculated with logistic regression analysis. A Markov model was used to construct a hypothetical cohort of workers with follow up of 40 years (40 cycles of 1 year) with transitional probabilities between no complaints, low back pain, and sickness due to low back pain. Permanent disability was used as end state of health.

Results

The transitional probability from no complaints to low back pain varied between p = 0.25 and p = 0.29, from low back pain to sickness absence between p = 0.09 and p = 0.25, and recurrence of sickness absence varied between p = 0.27 and p = 0.50, depending on the level of physical load. During a 40 year career, total sickness absence due to low back pain was approximately 140 weeks (6.6%) among workers with high physical load and about 30 weeks (1.4%) among those with low physical load.

Conclusion

The Markov approach illustrated the potential impact of physical load on (permanent) disability due to low back pain among workers with exposure to physical load. These consequences may go unnoticed in cohort studies with follow up periods of a few years.     

Advice given to patients about return to work and driving following surgery

BACKGROUND: The post-operative advice given to patients by health care practitioners regarding return to work and return to driving may have an impact upon their absence duration. The only guidance that is readily available to assist health care practitioners give this advice is provided by the Department of Work and Pensions (DWP). AIMS: To identify what advice local consultant surgeons, occupational physicians and general practitioners give to patients about return to work and driving, following benign abdominal hysterectomy (BAH) and Birmingham hip resurfacing (BHR). To explore health care practitioners' awareness of the DWP evidence-based return to work guidelines. METHOD: A questionnaire was administered to 216 health care practitioners, asking them about the advice they would give to patients undergoing BAH or BHR, regarding return to driving and return to work. RESULTS: Fifty-eight per cent of all health care practitioners that responded were unaware of the DWP evidence-based guidance. Seventy-four per cent of occupational physicians were aware of this guidance but only 32% of general practitioners and 0% of hospital specialists. The advice given regarding expected duration of sickness absence was very variable, ranging between 2 weeks and >12 weeks for both BAH and BHR procedures. Twenty-one different operative 'patient information sheets' were examined and these included only very brief and very general advice about return to work. CONCLUSION: National guidance on post-operative return to work advice could be beneficial. The guidance should be supported by health care practitioners and provide advice about normal ranges of time to return to driving and to return to work.     

Job satisfaction and short-term sickness absence among Dutch workers

BACKGROUND: Sickness absence is a considerable economic and social problem. Short-term sickness absence is known to be associated with behavioural attitudes. The correlation between sickness absence and job satisfaction has been studied infrequently and with contradictory results. AIMS: This study investigated the correlation between short-term sickness absence and both global and specific job satisfaction. We defined short-term sickness absence as spells of up to 42 days. METHODS: A random sample of 898 Dutch workers from a variety of economic sectors and companies received a self-report questionnaire on their first day of sick leave. The questionnaire measured global and specific job satisfaction. In our regression analysis, we controlled for the confounding factors of age, gender, educational level, perceived workload, job autonomy and decision latitude. The duration of an absence spell was defined as the amount of calendar days between sick leave and return to work. RESULTS: Global job satisfaction did not correlate significantly with the duration of short-term sickness absence. While increasing physical job demands predicted longer absence, increasing job autonomy and educational level predicted shorter absence. Satisfaction with colleagues predicted longer duration absence. CONCLUSION: Global job satisfaction did not correlate with the duration of short-term absence spells, but specific satisfaction with colleagues was associated with longer sickness spells.     

Smoking and sickness absence among public health workers

BACKGROUND: As well as causing sickness and death, smoking has high socio-economic costs. The aim of this paper was to examine how closely smoking is associated with sickness absence among healthcare workers. SUBJECTS AND METHODS: Cases and controls were paired by age, gender and occupation among primary healthcare workers in Tenerife, Canary Islands, Spain. Cases were selected from workers that had been absent from work due to sickness for 1 or more days in an entire year, regardless of the cause. Controls were those workers who were not absent due to sickness over the same period. Tobacco consumption was verified by telephone poll. Matched pairs analysis was performed. RESULTS: Among the 292 cases, 40% were smokers, compared with 31% of controls [odds ratio (OR)=1.51, 95% confidence intervals (CI)=1.06-2.14]. The association between smoking and sickness absence was stronger in those aged 30-45 years (OR=1.60, 95%CI=1.04-2.44) and among nurses (OR=2.08, 95%CI=1.05-4.14). When the cause of sickness absence was a respiratory disease, no association was found with smoking. However, an association was found with back pain (OR=5, 95%CI=1.45-17.27). Duration of tobacco consumption was higher in cases (a) when only current smokers were considered (P=0.002), and (b) when including the smoking duration of former smokers (P=0.0004). CONCLUSIONS: Smoking is associated with a higher risk of sickness absence among healthcare workers, particularly due to back pain. This could be used as an incentive to persuade healthcare workers to stop smoking and re-inforce the non-smoking message given to their patients.     

Return to work and adjustment latitude among employees on long-term sickness absence

Introduction: The aim was to study whether return to work (RTW) after long-term sickness absence is affected by adjustment latitude i.e. opportunities to adjust one's work to one's state of health by e.g. choosing among work tasks and deciding about work pace and working hours. We also studied whether the effect of adjustment latitude differed between those returning full-time and those returning part-time. Methods: Differences between men and women were also studied. A questionnaire was sent to 5,590 salaried employees who had been on sick leave for at least 90 days in 2000. The year after, 2001, they received a questionnaire which included questions about work status, working conditions, adjustment latitude and health. Results: The questionnaire was returned from 3056 persons. Among women 32% were fully back to work, 34% were partly back and 34% were still on sick leave. Comparable figures for men were 33%, 32% and 36%. Conclusion: For both men and women the likelihood to RTW increased with increasing number of opportunities to adjust. Adjustment latitude increased returning to part-time as well as full-time work. The study indicates that work organisation is important for RTW.     

Constructing health and sickness in the context of motherhood and paid work

Changes in the labour market, especially the rise in the employment of women (lone or partnered) with children, alongside an increased policy emphasis on work as a component of active citizenship for men and women, have stimulated the development of research examining the balance between work and home. Although sociologists have long been interested in the interface between the spheres of paid work and domestic life, understandings of the subjective experience of health and illness have tended to keep the domains of family and work separate. This paper addresses the construction of health and illness as operating at the interface between the worlds of work and home. Interviews were conducted with 30 mothers in paid work and having primary school aged children; the study was located in Edinburgh, Scotland. Through an analysis of the interview accounts, this paper examines respondents' experiences and constructions of health, sickness and wellbeing in themselves and in their children. Four areas are discussed: respondents' accounts of the effects of caring and providing on their own health; respondents' accounts of the influence of workplace relationships in the construction of sickness; respondents' accounts of negotiating absence for their children's sickness and how they made sense of and defined child sickness. We argue that managing sickness, itself an anticipated but unpredictable event, gives analytical purchase to understanding the values and practices that characterise the interrelationship between work and family life. The intersections of home and work operate powerfully in respondents' constructions of health and sickness, and the analysis demonstrates how these are played out in everyday life, at home and at work.     

A retrospective study of return to work following surgery

BACKGROUND: Sickness absence following surgery accounts for significant periods of sickness absence from employment. The duration of absence following two surgical procedures: benign abdominal hysterectomy (BAH) and Birmingham hip resurfacing (BHR) was explored. AIM: To identify what advice patients who had undergone BAH or BHR surgery were given regarding their likely sickness absence duration and to compare this with their reported absence duration. METHOD: In all, 453 patients who had undergone BAH or BHR surgery during 2004 were contacted by postal questionnaire and the results were statistically analysed. RESULTS: The advice given to patients to refrain from work varied from 4 weeks to >15 weeks for BAH surgery which was inconsistent with evidence-based guidance provided by the Department of Work and Pensions. The advice for BHR varied from <4 weeks to >15 weeks. Advice given by health care professionals appeared to have the greatest influence on return to work times with patients tending to adhere to any advice that is given irrespective of its duration. Twenty-two (29%) BAH patients and thirty-six (43%) BHR patients reported that their employers provided temporary work modifications when they returned to work; however, this support appeared to have no effect on their sickness absence duration. CONCLUSION: Health care professional advice regarding expected sickness absence duration influenced absence duration. The awareness and use of more consistent evidence-based guidance may be beneficial for all involved in this process.     

A longitudinal study of changes in interactional justice and subsequent short-term sickness absence among municipal employees

Objectives:Level of perceived interactional justice has been shown to be associated with sickness absence, but less is known about the effects of changes in interactional justice. It is also unknown to what extent unmeasured, time-invariant differences contribute to the association. We investigated the association between interactional justice changes and subsequent short-term (1–3 days) sickness absences over a 12-year follow-up using between- and within-individual modeling among ageing municipal employees.Methods:The data was derived from Helsinki Health Study cohort with baseline survey in 2000–2002 (N=8960, response rate 67%) and follow-up surveys in 2007 and 2012 (response rates 79% and 83%, respectively). At baseline, participants were 40–60-year-old employees of the City of Helsinki, Finland. Sickness absences from the employer’s registry were linked with the responses (78%). The analytic sample was 2109 and 2070 individuals for between-individual and 4433 individuals and 8425 observations for within-individual associations.Results:Negative change in interactional justice was associated with an increased risk of short-term sickness absence in between-individual models after adjusting for age and gender. Adjustment for sickness absence history attenuated the association. In within-individual models, a negative change in perceived interactional justice was associated with an increased risk of short-term sickness absence spells [incidence rate ratios (IRR) 1.05 (95% confidence interval 1.01–1.09)]. This association was robust to adjustments for gender, age, health behaviors and sickness absence history.Conclusions:Paying attention to management principles – especially managerial behavior and treatment of employees to avoid the deterioration of the level of interactional justice – may provide a way of reducing self-certified short-term sickness absence spells.     

Prospective study of physical and psychosocial risk factors for sickness absence

AIM: To investigate the associations between psychosocial and physical work environment exposures and sickness absence from work taking into account health, health behaviour and employer characteristics known to affect sickness absence. METHODS: In 1995, a random sample of 5574 employees aged 18-64 years were interviewed. In 2000, 3792 of those still employed supplied data on days absent from work the year preceding the date of follow-up. Associations between risk factors at baseline and sickness absence at follow-up were studied. Logistic regression analyses were performed. RESULTS: Sickness absence was associated with working with arms lifted/hands twisted, extreme bending/stooping of the back/neck, repetitive monotonous work, low skill discretion, low decision authority, obesity, current and former smoking, poor self-rated health, female gender, increasing age and public employer. The aetiological fraction attributable to differences in work environment exposures was calculated to be 40%. CONCLUSION: The study suggests a potential for reducing sickness absence through multifactorial interventions towards smoking, obesity, physical and psychosocial work environment exposures. The study showed that differences in work environment exposures account for 40% of the cases of high sickness absence.     

The associations of working hour characteristics with short sickness absence among part- and full-time retail workers

Objective:This study aimed to determine the associations of working hour characteristics with short (1–3 days) sickness absence (SA) among retail workers.Methods:As part of “RetailHours-project”, 4046 employees of 338 Finnish retail stores were included. Registry-based data on working hour characteristics and short SA were utilized. A case-crossover design was used and the odds ratios (OR) were controlled for the clustering effect and working hour characteristics.Results:There were strong dose–response relationships between percent of short (<11 hours) shift intervals and short SA among part- and full-time workers, men and women, and younger and older workers. Compared to workers without short shift intervals, the risk of SA was 1.47 times [95% confidence interval (CI) 1.29–1.68] higher among workers who had short shift intervals <10% of work times, 2.39 times (95% CI 2.03–2.82) higher among workers who had 10–25% of work times, and 4.03 times (CI 2.34–6.93) higher among workers who had short shift intervals >25% of work times. Weekly working hours >40 hours were associated with SA among part-time workers [odds ratio (OR) 2.22, CI 1.65–2.98], women (OR 1.62, CI 1.27–2.07) and among workers <30 years of age (OR 1.68, CI 1.20–2.35) as well as among workers aged ≥30 years (OR 1.43, CI 1.07–1.92). Furthermore, working mainly night shifts was associated with SA among full-time workers (OR 2.41, 95% CI 0.99–5.86) and women (OR 1.72, CI 1.02–2.89).Conclusions:A short shift interval is an important risk factor for short SA. Improving intervals between shifts and shortening long weekly working hours could reduce the risk of short SA among retail workers.
