Sickness absence due to musculoskeletal diagnoses and risk of diagnosis-specific disability pension: A nationwide Swedish prospective cohort study

Psychological problems among elementary and high school educators in Canada: association with sick days in the prior school year

Background

Increased sick leave among educators can detrimentally impact students' productivity, and academic achievement. It remains unknown whether the number of sick days taken by educators in the preceding school year correlates with the prevalence or severity of psychological problems among educators in the subsequent school year.

Objective

This study aimed to examine the number of self-reported sick days taken by educators in three Canadian provinces during the 2021/2022 academic year and its association with measures of stress, burnout, low resilience, depression, and anxiety during the 2022/2023 school year.

Methods

Data was collected from educators in three Canadian provinces, Alberta, Nova Scotia, and Newfoundland and Labrador, from September 1, 2022, to August 30, 2023. The Maslach Burnout Inventory-Educator Survey (MBI-ES), the Brief Resilience Scale (BRS), and the Perceived Stress Scale were used to assess burnout, resilience, and stress, respectively. Likely Generalized Anxiety Disorder (GAD) and likely Major Depressive Disorder (MDD) were assessed using the Generalized Anxiety Disorder-7 and Patient Health Questionnaire-9 scales, respectively. Statistical analysis was conducted using SPSS version 28.

Results

A total of 763 subscribers completed all the demographic, professional questions, and clinical scales, giving a response rate of 39.91%. Of these, there were 94 (12.3%) males and 669 (87.7%) females. Educators who reported taking 11 or more sick days in the previous academic year were at least three times more likely to exhibit high stress, emotional exhaustion, likely GAD, low resilience, and likely MDD than educators with no sick days during the preceding year. Similarly, educators with 11 or more sick days had significantly higher mean scores on the GAD-7 scale, the PHQ-9 scale, the PSS-10, the MBI Emotional Exhaustion subscale, and the MBI Depersonalization subscale than those with zero sick days.

Conclusion

This study demonstrates a significant association between sick days and the prevalence and severity of high stress, low resilience, burnout, anxiety, and depression among educators. Short-term sick leave can escalate into long-term absences without adequate support for teachers. Governments and policymakers in the education sector must foster a supportive environment that enables teachers to thrive and effectively perform their professional role without taking prolonged sick days, which can undermine student learning and achievement.

Sickness absence from work in the footwear industry: A longitudinal study

BACKGROUND: Studies on illness in the footwear industry have prioritized specific work sectors and diseases. OBJECTIVES: To analyze the main factors related to sickness absence and the indicators of illness in terms of recurrence and workdays lost among workers at a footwear company, ranging from storage of raw material to distribution of the final product. METHODS: A total of 9072 cases of absence from work were investigated in shoe production units from 2014 to 2017. Univariate models estimated the risk of bodily dysfunction (physiological and psychological) and the severity of recurrence and work days lost. RESULTS: (1) Most production units and work sectors were related to one or more affected bodily functions; (2) Neuromusculoskeletal and movement-related functions and the work sectors of prefabrication; cutting, assembly and finishing; and quality inspection of the final product required a longer recovery time before return to work and had a greater recurrence of leave; and (3) Women seemed to be more affected than men in terms of the reappearance of symptoms. CONCLUSIONS: Illness differs according to occupational sectors. The production sectors present more serious situations due to physical overload, intense rhythm and concentration, monotony and low autonomy.

Societal participation in ehlers-danlos syndromes and hypermobility spectrum disorder, compared to fibromyalgia and healthy controls

Ehlers-Danlos syndrome and hypermobility spectrum disorder affect daily life. There is a lack of research that investigates how the disease affects aspects of participation. This study investigates whether there is a difference in the level of participation in society in persons with vascular EDS (N = 18), hypermobile EDS (N = 20), classical EDS (N = 4) and Hypermobility Spectrum Disorder (N = 27), compared to a healthy control group (N = 69) and fibromyalgia (N = 69). In this retrospective case-control study, the Ghent Participation Scale was completed by all participants. Each patient with EDS and HSD was matched by age and sex to healthy controls. The hEDS and HSD group were compared with the healthy control group and a positive control group (persons with fibromyalgia). The results show that there was a significant lower overall participation score for persons with hEDS/HSD compared to the healthy control group. In addition, significant differences were observed in the subscores self-performed activities and delegated activities in the hEDS/HSD group compared to healthy controls, being HEDS/HSD patients who obtained the lower scores. Further research is needed to obtain representative results of the participation level for the EDS/HSD population. In this way, interventions can be set up for patients with EDS in an evidence-based way and that are appropriate to the patient’s level of participation.

Predictors of Sickness Absence in a Clinical Population With Chronic Pain

Chronic pain-related sickness absence is an enormous socioeconomic burden globally. Optimized interventions are reliant on a lucid understanding of the distribution of social insurance benefits and their predictors. This register-based observational study analyzed data for a 7-year period from a population-representative sample of 44,241 chronic pain patients eligible for interdisciplinary treatment (IDT) at specialist clinics. Sequence analysis was used to describe the sickness absence over the complete period and to separate the patients into subgroups based on their social insurance benefits over the final 2 years. The predictive performance of features from various domains was then explored with machine learning-based modeling in a nested cross-validation procedure. Our results showed that patients on sickness absence increased from 17% 5 years before to 48% at the time of the IDT assessment, and then decreased to 38% at the end of follow-up. Patients were divided into 3 classes characterized by low sickness absence, sick leave, and disability pension, with eight predictors of class membership being identified. Sickness absence history was the strongest predictor of future sickness absence, while other predictors included a 2008 policy, age, confidence in recovery, and geographical location. Information on these features could guide personalized intervention in the specialized healthcare. PERSPECTIVE: This study describes sickness absence in patients who visited a Swedish pain specialist interdisciplinary treatment clinic during the period 2005 to 2016. Predictors of future sickness absence are also identified that should be considered when adapting IDT programs to the patient's needs.

Musculoskeletal pain intensity in different body regions and risk of disability pension among female eldercare workers: prospective cohort study with 11-year register follow-up

Background

Musculoskeletal pain is a risk factor for leaving the labour market temporarily and permanently. While the presence of multi-site pain increases the risk of disability pension, we lack detailed knowledge about pain intensity as a risk factor. This study investigated the association between musculoskeletal pain intensity in different body regions and risk of future disability pension among eldercare workers.

Methods

Eight thousand seven hundred thirty-one female eldercare workers replied to a questionnaire on work and health in 2005 and were followed for 11 years in the Danish Register for Evaluation of Marginalization. Time-to-event analyses estimated hazard ratios (HR) for disability pension from pain intensities (0–9 numeric rating scale (NRS)) in the low-back, neck/shoulders, and knees during the previous 3 months. Analyses were mutually adjusted for pain regions, age, education, lifestyle, psychosocial work factors, and physical exertion at work.

Results

During 11-year follow-up, 1035 (11.9%) of the eldercare workers received disability pension. For all body regions among all eldercare workers, dose-response associations were observed between higher pain intensity and risk of disability pension (p < 0.001). The risk for disability pension was increased when reporting “very high” pain levels (≥7 points on the 0–9 NRS) in the low-back (HR 2.19, 95% CI 1.70–2.82), neck/shoulders (HR 2.34, 95% CI 1.88–2.92), and knees (HR 1.89, 95% CI 1.44–2.47). Population attributable risks (PAR) were 15.5, 23.2, and 9.6% for pain > 2 on NRS in the low-back, neck/shoulders, and knees, respectively, indicating that 15.5, 23.2, and 9.6% fewer eldercare workers would likely receive disability pension if the pain intensity was reduced to 2 or less. For workers ≤45 years and > 45 years, PAR was highest for neck/shoulder pain (27.6%) and low-back pain (18.8%), respectively.

Conclusions

The present study found positive dose-response associations between pain intensity in the low-back, neck/shoulders, and knees, and risk of disability pension during 11-year follow-up. Moderate to very high levels of musculoskeletal pain in eldercare workers should, therefore, be considered an early warning sign of involuntary premature exit from the labour market. These findings underscore the importance of preventing, managing, and reducing musculoskeletal pain to ensure a long and healthy working life.

Number of Pain Locations as a Predictor of Cause-Specific Disability Pension in Sweden-Do Common Mental Disorders Play a Role?

OBJECTIVE

The aim of this study was to investigate the associations between number of pain locations, common mental disorders (CMDs), and disability pension (DP).

METHODS

Survey data in 1998 to 2003 for 27,165 Swedish twins born in 1935 to 1958 were linked to national DP data until 2013. Pain locations were evaluated for back, low back, sciatica, shoulder, or neck pain, and CMDs for lifetime major depression and 1-month anxiety.

RESULTS

The number of pain locations was associated with DP in a dose-response manner. One pain location had a hazard ratio of 1.50 (95% confidence interval 1.35 to 1.68) and five pain locations hazard ratio 4.67 (95% confidence interval 4.11 to 5.30) for DP. Also, CMDs were associated with DP.

CONCLUSION

The number of pain locations has a dose-response association with the risk of DP. CMDs predict DP. In strategies to prevent DP, early signs of pain or CMDs should be taken into consideration.

From long-term sickness absence to disability retirement: diagnostic and occupational class differences within the working-age Finnish population

Background

It is well documented that sickness absence is strongly associated with disability retirement. A long-term sickness absence (LTSA) in particular increases the risk of disability retirement, but little is known about the variation of this risk across diagnostic causes. Further, as occupational classes differ in their diagnostic profiles, it is likely that the role of diagnosis in the pathway from LTSA to disability retirement varies between occupational classes. We examined how LTSA of different diagnostic causes predicts all-cause disability retirement and disability retirement due to the same diagnostic group or due to some other diagnostic group than that which caused the LTSA spell in different occupational classes.

Methods

Cox proportional hazards models were used to analyse a 70% random sample of all employed Finns aged 25–62 Finns in 2006 (N = 1,458,288). Disability retirement was followed from 2007 to 2014. The risk of disability retirement was compared between occupational classes with at least one LTSA spell due to musculoskeletal diseases, mental disorders, respiratory diseases, or circulatory diseases and those who had no LTSA spells due to these diagnostic groups during 2005.

Results

Those who had LTSA due to musculoskeletal diseases or mental disorders transferred more often to disability retirement due to same diagnostic group, whereas those who had LTSA due to respiratory or circulatory diseases transferred more often to disability retirement due to some other diagnostic group. The largest occupational class differences in all-cause disability retirement were found among those with LTSA due to mental disorders. For men, the hazard ratios (HR) varied from HR 5.70 (95% confidence interval (CI) 5.00–6.52) in upper non-manual employees to 2.70 (95% CI 2.50–2.92) in manual workers. For women, the corresponding HRs were 3.74 (95% CI 3.37–4.14) in upper non-manual employees and 2.32 (95% 2.17–2.50) in manual workers.

Conclusions

The association between LTSA and disability retirement varies between diagnostic groups, and the strength of this association further depends on the person’s occupational class and gender.

Work disability patterns before and after incident acute myocardial infarction and subsequent risk of common mental disorders: A Swedish cohort study

This study investigated the extent to which work disability patterns including sickness absence and disability pension (SA/DP) before and after acute myocardial infarction (AMI) were associated with subsequent common mental disorders (CMDs) such as depression and anxiety in AMI patients without previous CMD. Total 11,493 patients 26–64 years with incident AMI during 2008–10 were followed up for CMD (measured as antidepressant prescription) through 2013. Four SA/DP trajectory groups during the 3-years pre-AMI and 1-year post-AMI were identified. Hazard ratios (HRs) with 95% confidence intervals for subsequent CMD were estimated in Cox models. Higher pre-AMI SA/DP annual levels (>1–12 months/year) were associated with 40–60% increased CMD rate than the majority (78%) with low increasing levels (increasing up to 1 month/year). Regarding post-AMI findings, constant high (~25–30 days/month) SA/DP levels within the first 3 months was associated with a 76% higher CMD rate, compared to constant low (0 days/month). A gradually decreasing post-AMI SA/DP pattern over a 12-month period suggested protective influences for CMD (HR = 0.80). This is the first study to demonstrate that pre- and post-AMI work disability patterns are associated with subsequent CMD risk in AMI patients. Work disability patterns should be considered as an indicator of AMI prognosis in terms of CMD risk.

Compensation claims for work-related musculoskeletal disorders among hairdressers in France, 2010-2016

Background. Hairdressers in France experience occupational illness as well as stressful working conditions which can result in permanent incapacity mainly due to work-related musculoskeletal disorders (WRMSDs), yet WRMSDs in this workforce remain largely unstudied. Objective. The aim of this study was to analyze trends in compensation claims for WRMSDs among hairdressers. Methods. Data concerning gender, age, permanent incapacity, working experience and lost work days (LWD) of claimants were extracted from the French National Health Insurance Fund for Salaried Workers. Results. The claim rate increased non-significantly by 12.8% during the study period. The incidence rate of permanent incapacity increased significantly by 16.0%. In proportion, significant differences were observed between age groups, with age 35-49 years ranking first (45.8%), and also in claimants with working experience > 10 years (43.1%). Overall, there were 666,461 LWD during the study period with a significant increase of 16.2% (p < 0.001). Conclusion. Although the claims rate did not increase significantly, the incidence rate of permanent incapacity increased significantly and some groups at risk have been indentified.

Sickness absence as a predictor of disability retirement in different occupational classes: a register-based study of a working-age cohort in Finland in 2007-2014

OBJECTIVES

The objective of the study was to examine diagnosis-specific sickness absences of different lengths as predictors of disability retirement in different occupational classes.

DESIGN

Register-based prospective cohort study up to 8 years of follow-up.

PARTICIPANTS

A 70% random sample of the non-retired Finnish population aged 25-62 at the end of 2006 was included (n=1 727 644) and linked to data on sickness absences in 2005 and data on disability retirement in 2007-2014.

MAIN OUTCOME MEASURES

Cox proportional hazards regression was utilised to analyse the association of sickness absence with the risk of all-cause disability retirement during an 8-year follow-up.

RESULTS

The risk of disability retirement increased with increasing lengths of sickness absence in all occupational classes. A long sickness absence was a particularly strong predictor of disability retirement in upper non-manual employees as among those with over 180 sickness absence days the HR was 9.19 (95% CI 7.40 to 11.40), but in manual employees the HR was 3.51 (95% CI 3.23 to 3.81) in men. Among women, the corresponding HRs were 7.26 (95% CI 6.16 to 8.57) and 3.94 (95% CI 3.60 to 4.30), respectively. Adjusting for the diagnosis of sickness absence partly attenuated the association between the length of sickness absence and the risk of disability retirement in all employed groups.

CONCLUSIONS

A long sickness absence is a strong predictor of disability retirement in all occupational classes. Preventing the accumulation of sickness absence days and designing more efficient policies for different occupational classes may be crucial to reduce the number of transitions to early retirement due to disability.

New episodes of musculoskeletal conditions among employed people in Norway, sickness certification and return to work: a multiregister-based cohort study from primary care

OBJECTIVES

To identify new cases of musculoskeletal (MSK) disorders among employed people presenting in Norwegian primary care in 2012, frequency of sickness certification and length of sick leave. To identify patient-, diagnosis- and GP-related predictors of sickness certification, prolonged sick leave and return to work (RTW).

METHODS

An observational multiregister-based cohort study covering all employed persons in Norway(1 176 681 women and 1 330 082 men) based on claims data from all regular GPs merged with individual sociodemographic data from public registers was performed. Participants were employed patients without any GP consultation during the previous 3 months who consulted a GP with a diagnosis of a MSK condition. Those not on sick leave and with a known GP affiliation were included in the analyses. Outcomes were incidence, proportion sickness certified and proportion on sick leave after 16 days, according to the diagnosis, ORs with 95% CIs for sickness certified and for sick leave exceeding 16 days and HRs with 95% CIs for RTW.

RESULTS

One-year incidence of MSK episodes was 159/1000 among employed women and 156/1000 among employed men. 27.1% of the women and 28.2% of the men were sickness certified in the initial consultation. After 16 days, 10.5% of women and 9.9% of men were still on sick leave. Upper limb problems were most frequent. After adjustments, medium/high education predicted a lower risk of absence from work due to sickness and rapid RTW after 16 days. Back pain, fractures and female gender carried a higher risk of sickness certification but faster RTW. Older age was associated with less initial certification, more sick leave exceeding 16 days and slower RTW. Male patients with male GPs had a lower risk of sickness absence, which was similar to patients with GPs born in Norway and GPs with many patients. After 16 days, GP variables had no effect on RTW.

CONCLUSION

Upper limb problems and GPs as stakeholders in 'the inclusive workplace' strategy need more attention.

Afastamento do trabalho e os percursos terapêuticos de trabalhadores acometidos por LER/Dort

RESUMO O estudou objetivou investigar os percursos terapêuticos de trabalhadores em situação de afastamento do trabalho por Lesões por Esforços Repetitivos/Distúrbios Osteomusculares Relacionados ao Trabalho (LER/Dort) atendidos em um serviço de saúde. Ocorreu análise de prontuários clínicos e seleção de sujeitos para entrevistas semiestruturadas, que foram gravadas para análise de conteúdo temática. Participaram das entrevistas dez trabalhadores, de ambos os gêneros e diferentes profissões. Os sujeitos passaram por condutas clínicas embasadas no modelo biomédico, pelo desamparo da empresa e do Instituto Nacional do Seguro Social (INSS), gerando sofrimento. Concluiu-se que ainda há necessidade de melhorias nas ações intersetoriais e interdisciplinares em casos de doenças crônicas e no modelo integral de saúde.

A saúde em troca da excelência: o sofrimento de atendentes de nutrição de um hospital público acometidos por LER/Dort

Resumo Este artigo apresenta resultados de pesquisa cujo objetivo foi compreender as relações entre os aspectos da organização do trabalho e a saúde de atendentes de nutrição acometidos por LER/Dort. Durante o processo houve levantamento de estatísticas de absenteísmo relacionado a LER/Dort em um hospital público em Porto Alegre/RS, no período de 1 de junho de 2015 a 30 de junho de 2016, e seleção da Seção de Distribuição de Alimentos e de seus atendentes de nutrição para aprofundamentos. Foram utilizados um questionário estruturado com dados sociodemográficos e de trabalho e o instrumento Self-Reporting Questionnaire (SRQ-20), para pesquisar a prevalência de transtornos mentais comuns (TMC), e realizadas entrevistas coletivas com os atendentes acometidos por LER/Dort, utilizando o referencial teórico da psicodinâmica do trabalho. Os resultados obtidos apontaram para modos de organização do trabalho e gestão com cobranças excessivas, assédio moral e falta de reconhecimento no trabalho, que geram sofrimento e influenciam nos processos de adoecimento. Sugere-se um espaço de escuta e discussões com reuniões que envolvam os trabalhadores, técnicos de nutrição e a coordenação que possam caracterizar uma ação permanente.

The association of mobility disability and weight status with risk of disability pension: A prospective cohort study

BACKGROUND/AIMS

Mobility disability (MD) and obesity are conditions which have been associated with weaker labour market attachment. This study investigates whether the combined burden of MD and obesity increase the risk of disability pension compared with having only one of these conditions (the reference group).

METHODS

A nationwide cohort study, based on national surveys made between 1996 and 2011, was conducted including 50,015 individuals aged 19-64 years who were followed-up in a large database in terms of attainment of disability pension until 31 December 2012 (at the latest). Proportional hazards regression models were used to analyse the risk of all-cause and diagnosis-specific disability pension with six exposure groups, established by mobility and weight status (BMI) obtained through self-reports.

RESULTS

A total of 2296 participants had received disability pension after a mean follow-up period of 7.2 years (SD 4.6). People with MD, regardless of weight, had 4-8 times higher risk of disability pension (for any reason) compared with the reference group (individuals with normal weight and no MD).

CONCLUSIONS

No evidence of a double burden of MD and obesity with disability pension was observed in this study. MD seemed to contribute more to the risk of disability pension than weight status. In a long-term perspective, society and also people at risk of these disabling conditions would benefit from reallocation of resources from disability pensions to health-promoting and preventive policies, not least targeting MD.

Socio-economic factors associated with the 1‑year prevalence of severe pain and pain-related sickness absence in the Austrian population

Background

The aim of this study was to (1) investigate the relation of socio-economic status (SES), measured as education, occupation, and income, with the 12-month prevalence of severe pain and with pain-related sickness absence, and (2) analyse to what extent sociodemographic and medical factors influence these associations.

Methods

The study population comprised 8084 subjects aged between 15 and 65 years from the Austrian Health Interview Survey in 2006/07. Associations of SES with the 1‑year prevalence of severe pain and sickness absence due to pain in those with severe pain was assessed with logistic regression analysis and adjusted for socio-demographic and chronic medical conditions.

Results

The 1‑year prevalence of severe pain was 33.7%. Among those with severe pain, 32.9% were on sickness absence due to pain. SES was significantly associated with the prevalence of severe pain and even more strongly with sickness absence due to pain. Stepwise adjustment for socio-demographics and medical factors had only marginal effects on these associations. Multivariate odds ratios (ORs) for severe pain were 1.14; 1.18 and 1.32 for low income, blue-collar workers, and low education, respectively. Related ORs for sickness absence due to pain were 1.52; 1.14 and 2.05.

Conclusions

There was an association between SES, particularly measured as educational level, and the prevalence of severe pain, which was even stronger with sickness absence due to pain.

Work disability before and after a major cardiovascular event: a ten-year study using nationwide medical and insurance registers

We examined the trajectories of work disability before and after IHD and stroke events. New IHD (n = 13521) and stroke (n = 7162) cases in 2006–2008 were retrieved from nationwide Swedish hospital records and their annual work disability days five years before and after the date of diagnosis were retrieved from a nationwide disability register. There was no pre-event differences in disability days between the IHD and stroke cases and five years prior to the event, they were close to those observed in the general population. In the first post-event year, the adjusted mean days increased to 83.9 (95% CI 80.6–86.5) in IHD; to 179.5 (95% CI 172.4–186.8) in stroke, a six-fold increase in IHD and 14-fold in stroke. Work disability leveled off among the IHD cases but not among those who had stroke. The highest disability levels for the fifth post-event year after a stroke event was associated with pre-existing diabetes (146.9), mental disorder (141.2), non-employment (137.0), and immigrant status (117.9). In a working-age population, the increase in work disability after a cardiovascular event decreases close to the pre-event level in IHD but remains particularly high after stroke; among patients with comorbid depression or diabetes, immigrants, and those not in employment.

Predictive validity of the Work Ability Index and its individual items in the general population

Aim: This study assesses the predictive ability of the full Work Ability Index (WAI) as well as its individual items in the general population. Methods: The Work, Health and Retirement Study (WHRS) is a stratified random national sample of 25–75-year-olds living in Sweden in 2000 that received a postal questionnaire ( n = 6637, response rate = 53%). Current and subsequent sickness absence was obtained from registers. The ability of the WAI to predict long-term sickness absence (LTSA; ⩾ 90 consecutive days) during a period of four years was analysed by logistic regression, from which the Area Under the Receiver Operating Characteristic curve (AUC) was computed. Results: There were 313 incident LTSA cases among 1786 employed individuals. The full WAI had acceptable ability to predict LTSA during the 4-year follow-up (AUC = 0.79; 95% CI 0.76 to 0.82). Individual items were less stable in their predictive ability. However, three of the individual items: current work ability compared with lifetime best, estimated work impairment due to diseases, and number of diagnosed current diseases, exceeded AUC > 0.70. Excluding the WAI item on number of days on sickness absence did not result in an inferior predictive ability of the WAI. Conclusions: The full WAI has acceptable predictive validity, and is superior to its individual items. For public health surveys, three items may be suitable proxies of the full WAI; current work ability compared with lifetime best, estimated work impairment due to diseases, and number of current diseases diagnosed by a physician.

Job demands and decision control predicted return to work: the rapid-RTW cohort study

Background

In order to help workers with long-term sickness absence return to work (RTW), it is important to understand factors that either impede or facilitate employee’s reintegration into the labour force. The aim of this study was therefore to examine the impact of psychological work characteristics on time-to first RTW in sick listed employees in Norway.

Methods

The study was designed as a cohort study of 543 employees participating in 50 different RTW programmes. The Job Content Questionnaire (JCQ) was used to gather information on the psychological work conditions. The participants were followed for up to 18 months after they started treatment in the RTW programme. Survival analyses were used to investigate the association between psychological work conditions and time-to first RTW.

Results

Having high psychological job demands (HR = .654; 95% CI: .513–.832) and low decision control (HR = 1.297; 95% CI: 1.010–1.666) were both independent predictors of delayed RTW. Employees in low-strain jobs (low demands/high control) (HR = 1.811; 95% CI: 1.287–2.549) and passive jobs (low demands/low control) (HR = 1.599; 95% CI: 1.107–2.309), returned to work earlier compared to employees in high-strain jobs (high demands/low control). No difference was found for active jobs (high demands/high control).

Conclusion

This study revealed that high psychological demands, low control, and being in a high strain job reduced the probability of early RTW in sick listed employees. RTW programmes should therefore increase the focus on these issues.

Early retirement among Danish female cleaners and shop assistants according to work environment characteristics and upper extremity complaints: an 11-year follow-up study

Background

Studies have shown a negative social gradient in the incidence of early retirement. To prevent undesired early retirement, there is a need for knowledge of specific predictors in addition to social factors with a limited potential for change. The main purpose of this study was to examine musculoskeletal complaints and working conditions as predictors of early retirement among Danish female cleaners.

Methods

Using Cox regression with an adjustment for extraneous factors, we compared the risk of disability pension and retirement before the nominal retirement age (65 years) in an 11-year cohort study with registry-based follow-up of 1430 female cleaners and 579 shop assistants. In subsequent analyses of female cleaners, disability pension and voluntary early retirement were modeled according to work characteristics and upper extremity complaints.

Results

The adjusted hazard rate (HR) for disability pension among cleaners compared to the control group was 2.27 (95 % CI 1.58 to 3.28) and, for voluntary early retirement, 1.01 (95 % CI 0.85 to 1.20). In the subset of cleaners, the predictors of disability pension were persistent shoulder pain HR: 1.98 (95 % CI 1.47 to 2.67), elbow pain HR: 1.41 (95 % CI 1.02 to 1.94) and symptoms of nerve entrapment of the hand HR: 1.58 (95 % CI 1.14 to 2.20). Predictors of voluntary early retirement were persistent shoulder pain HR: 1.40 (95 % CI 1.16 to 1.67) and floor mopping for more than 10 h per week HR: 1.20 (95 % CI 1.03 to 1.40).

Conclusion

Cleaners have a twofold higher risk of disability pension compared to the control group. Risk factors for disability pension among cleaners were persistent shoulder and elbow pain together with symptoms of nerve entrapment of the hand. The findings of specific health related predictors of early retirement could be used in secondary prevention with targeted temporary reduced workload.

Exposure to different lengths of sick leave and subsequent work absence among young adults

BACKGROUND

Sweden has a public and easily accessible sickness insurance. Research shows, however, downsides to taking sick leave. Both short and longer periods of sick leave have been seen to increase the risk for subsequent work absence. The aim of this study was to investigate whether there was an association between sick leave claimed in 1993 and work absence in the subsequent 15 years, i.e. up to 2008. A further aim was to explore differences in this relation with regard to gender, origin and educational level at baseline.

METHODS

Our cohort consisted of all immigrants aged 21-25 years in Sweden in 1993 and a control group of native Swedes in the same age group.

RESULTS

Subsequent work absence increased from 313 days among persons with no days of claimed sick leave in 1993 to 567 days among persons with 1-7 days of claimed sick leave in 1993. Thereafter there was a lower, but steady increase in days of future work absence, to 611 days among persons with 8-14 days of sick leave claimed in 1993. There was an interaction between sick leave and gender, education and origin respectively regarding later work absence.

CONCLUSION

Periods of sick leave claimed were associated with subsequent work absence. Immigrants, women and persons with low education had the most risk of future work absence after a period of sick leave.

Trends of diagnosis-specific work disability after newly diagnosed diabetes: a 4-year nationwide prospective cohort study

OBJECTIVE

We examined trends of diagnosis-specific work disability after newly diagnosed diabetes, comparing individuals with diabetes with those without diabetes, and identified the subgroups with the highest levels of work disability.

RESEARCH DESIGN AND METHODS

The register data of diabetes medication and in- and outpatient hospital visits were used to identify all recorded new diabetes cases among the population aged 25-59 years in Sweden in 2006 (n = 14,098). Data for a 4-year follow-up of ICD-10 physician-certified sickness absence and disability pension days (2007‒2010) were obtained from the Swedish Social Insurance Agency. Comparisons were made using a random sample of the population without recorded diabetes (n = 39,056).

RESULTS

The most common causes of work disability were mental and musculoskeletal disorders; diabetes as a reason for disability was rare. Most of the excess work disability among people with diabetes compared with those without diabetes was owing to mental disorders (mean difference adjusted for confounding factors 18.8‒19.8 compensated days/year), musculoskeletal diseases (12.1‒12.8 days/year), circulatory diseases (5.9‒6.5 days/year), diseases of the nervous system (1.8‒2.0 days/year), and injuries (1.0‒1.2 days/year). The disparity in mental disorders first widened and then narrowed, while the difference in other major diagnostic categories was stable over 4 years. The highest rate (45.3 days/year) was found among people who had diabetes, lived alone, and were disabled from work owing to mental disorders.

CONCLUSIONS

The increased risk of work disability among those with diabetes is largely attributed to comorbid mental, musculoskeletal, and circulatory diseases. It is important to monitor comorbid conditions and take account of socioeconomic disadvantage.

Self-Reported and Tested Function in Health Care Workers with Musculoskeletal Disorders on Full, Partial or Not on Sick Leave

PURPOSE

The aim of this study was to describe self-reported and physically tested function in health care workers with musculoskeletal disorders (MSDs) and to examine how function was associated with work participation.

METHODS

A cross-sectional study was conducted. 250 health care workers attended an evaluation where self-reported and physical function were measured. Differences between groups (full sick leave, partial sick leave, not on sick leave/working) were analyzed for categorical data (Chi square exact test) and continuous variables (Kruskal-Wallis and Mann-Whitney U tests). Logistic regression analysis was performed to examine which factors were associated with being on sick leave.

RESULTS

Participants on full sick leave had statistically significant poorer function compared to those working and the group on partial sick leave. Logistic regression showed that a reduced level of the physical dimension of SF-12 and a high lift test were significantly related to full sick leave (OR 0.86, p < 0.001) (OR 0.79, p = 0.002). The physical dimension of SF-12 was the only variable that was associated to partial sick leave (OR 0.91, p = 0.005).

CONCLUSION

Health care workers on full sick leave due to MSDs have reduced function on self-reported and physically tested function, compared to those working despite MSDs, as well as when compared to those on partial sick leave. More knowledge about work ability in occupational sub-groups is needed.

Supervisors' Strategies to Facilitate Work Functioning among Employees with Musculoskeletal Complaints: A Focus Group Study

AIM

To explore what strategies the supervisors found beneficial to prevent or reduce sickness absence among employees with musculoskeletal complaints.

METHODS

Five focus groups were conducted and 26 supervisors from health and social sector participated. Commonly used strategies to prevent sickness absence and interdisciplinary cooperation in this work were discussed in the focus groups. Systematic text condensation was used to analyse the data.

RESULTS

The supervisors described five strategies for sick leave management: (1) promoting well-being and a healthy working environment, (2) providing early support and adjustments, (3) making employees more responsible, (4) using confrontational strategies in relation to employees on long-term sick leave, and (5) cooperation with general practitioners (GPs).

CONCLUSIONS

Strategies of promoting a healthy working environment and facilitating early return to work were utilised in the follow-up of employees with musculoskeletal complaints. Supportive strategies were found most useful especially in the early phases, while finding a balance between being supportive, on one side, and confronting the employee, on the other, was endeavoured in cases of recurrent or long-term sick leave. Further, the supervisors requested a closer cooperation with the GPs, which they believed would facilitate return to work.

Work disability before and after diabetes diagnosis: a nationwide population-based register study in Sweden

OBJECTIVES

We evaluated the risk of work disability (sick leave and disability pension) before and after diabetes diagnosis relative to individuals without diabetes during the same time period, as well as the trajectory of work disability around the diagnosis.

METHODS

This Swedish population-based cohort study with register data included 14 428 individuals with incident diabetes in 2006 and 39 702 individuals without diabetes during 2003 to 2009.

RESULTS

Work disability was substantially higher among people with diabetes (overall mean = 95 days per year over the 7 years, SD = 143) than among those without diabetes (mean = 35 days, SD = 95). The risk of work disability was slightly higher after diabetes diagnosis than before and compared with the risk of those without diabetes. The trajectory of work disability was already increasing before diagnosis, increased even more at the time of diagnosis, and leveled off after diagnosis. Individual sociodemographic characteristics and comorbid conditions contributed both to the risk and to the trajectory of work disability.

CONCLUSIONS

Although diabetes has an independent effect on work disability, sex, age, education, and comorbid conditions play a significant role.

Sickness absence due to back pain or depressive episode and the risk of all-cause and diagnosis-specific disability pension: A Swedish cohort study of 4,823,069 individuals

BACKGROUND

The aim of this study was to investigate the associations between sickness absence due to back pain or depressive episode with future all-cause and diagnosis-specific disability pension, while adjusting for comorbidity and socio-demographics, for all and stratifying for sex.

METHOD

In total, 4,823,069 individuals aged 16-64 years, living in Sweden at the end of 2004, not on old-age or disability pension in 2005 and without ongoing sickness absence at the turn of 2004/2005 formed the study population. Crude and adjusted hazard ratios (HRs) for all-cause and diagnosis-specific disability pension (2006-2010) in relation to diagnosis-specific sickness absence with sickness benefits paid by the Social Insurance Agency were estimated using Cox regression.

RESULTS

The HR for all-cause disability pension was 7.52 (7.25-7.52) in individuals with an incident sick-leave spell due to back pain, compared to individuals without sickness absence in 2005 in the fully adjusted (socio-demographics and comorbidity) model. The fully adjusted (multivariate) HRs for diagnosis-specific disability pension were musculoskeletal diagnoses 23.87 (22.75-25.04), mental 2.49 (2.27-2.73) or all other diagnoses, 3.44 (3.17-3.75). In individuals with an incident sick-leave spell due to a depressive episode in 2005, the multivariate adjusted HR for all-cause disability pension was 12.87 (12.42-13.35), while the multivariate HRs for disability pension due to musculoskeletal diagnoses were 4.39 (3.89-4.96), for mental diagnoses 25.32 (24.29-26.38) and for all other somatic diagnoses 3.44 (3.09-3.82). Men who were sickness absent due to a depressive episode had a higher HR for disability pension compared to women.

CONCLUSION

Results indicate that sickness absence due to a depressive episode or back pain is a strong risk factor for a future disability pension due to mental, musculoskeletal or other somatic diagnoses.
