Determinants of disability pension applications and awarded disability pensions in Finland, 2009 and 2014

Rejected sickness cash benefit claims after 180 days of sick leave in the Swedish rehabilitation chain: A nationwide register-based study

AIM

Since a lack of financial security among vulnerable groups could further hamper health and well-being, this study scrutinises factors predicting rejected prolonged sickness cash benefit claims among people on compensated sick leave of more than 180 days with a rejection between days 181 and 365.

METHODS

All 246,872 claims for employed people on sick leave recorded in the Swedish official statistics register between January 2018 and June 2021 were analysed. Claim outcome was evaluated using logistic regression with odds ratios recalculated to relative risks (RR) with 95% confidence intervals (CI), mutually adjusted for sociodemographic, work and health-related factors.

RESULTS

Overall, 46,611 (19%) of the claims were rejected, with slightly lower rates among women (RR=0.97; 95% CI 0.95-0.99). Musculoskeletal diseases had the highest rejection rates (RR=1.84; 95% CI 1.75-1.94) followed by injuries (RR=1.57; 95% CI 1.50-1.64) and symptoms (RR=1.51; 95% CI 1.46-1.56). Mental disorders also had above-average rates (RR=1.14; 95% CI 1.09-1.19), whereas the lowest rates were found among pregnancy-related diagnoses (RR=0.13; 95% CI 0.12-0.14) and neoplasms (RR=0.18; 95% CI 0.18-0.18). Higher rates were found among immigrants (RR=1.37; 95% CI 1.34-1.40), those with only primary education (RR=1.09; 95% CI 1.06-1.12) and among blue-collar workers. The regional variation was substantial (RR range 0.41-1.72).

CONCLUSIONS

High rejection rates were found for complex diagnoses and diagnoses with presupposed work ability in physically lighter occupations and among groups with assumed precarious positions at the labour market. Systematic differences in rates were identified between geographic regions. More studies are warranted to conclude if the differences found could be justified by other factors.

Physical Fitness as a Predictor of Disability Retirement: A 9-Year Register Linked Follow-Up Study

BACKGROUND

To prospectively examine the association between physical fitness and risk of disability retirement in a large population-based cohort.

METHODS

This study utilized data from Health 2011 survey Physical Activity subsample (n = 4898), combined with information on disability retirement derived from 2 national registers. In total, 2455 individuals aged 18-74 years underwent the physical fitness test protocol concerning measures of cardiorespiratory fitness, muscle strength, and balance. The outcome variable was disability retirement, during the follow-up period of 9 years. After excluding those not at risk of disability retirement (ie, age ≥63 y) or who had already been granted disability pension, and those who had not completed the fitness protocol, the analytical sample included 1381 participants. Data were analyzed using Cox regression model with SPSS (version 29).

RESULTS

During the 9-year follow-up period, 61 individuals (4.4%) transitioned to a disability retirement. Cox regression analysis showed an association between the various physical fitness subdomains and the risk of disability retirement. In model 1, all fitness tests were associated with the risk of disability retirement, except the one-leg stand test with hazard ratios ranging from 1.69 (95% CI, 0.86-3.34) to 5.75 (95% CI, 1.84-17.90). Further adjustment for sociodemographic, health behavior, and health-related covariates attenuated the associations and statistical significance was lost, except for the vertical jump test (hazard ratio = 4.33; 95% CI, 1.32-14.10) and 6-minute walk test (hazard ratio = 3.81; 95% CI, 1.35-10.70).

CONCLUSION

These findings highlight the importance of physical fitness for preventing work disability.

Unemployed and disabled for work: identifying 3-year labour market pathways from the beginning of a sickness absence using sequence and cluster analyses in a register-based longitudinal study in Finland

OBJECTIVES

This study followed the labour market pathways of unemployed persons who started a sickness absence (SA) spell. We aimed to unravel subgroups based on altering labour market states and to identify covariates of these subgroups.

DESIGN

Register-based longitudinal study, with nine labour market states and 36-month units.

SETTING AND PARTICIPANTS

All Finnish persons aged 18-59 years with an SA in 2016 who were unemployed at the start of the SA spell (N=12 639).

OUTCOME MEASURES

Sequence analysis was used to study transitions between nine labour market states based on monthly register data on permanent and temporary (full and partial) disability pensions (DP), rehabilitation, all-cause SA, unemployment and employment. Individuals were grouped into clusters based on cluster analysis and intersequence distances. Multinomial regression analysis was used to examine covariates of cluster memberships.

RESULTS

Six clusters with the following pathway identities were found: (1) recurring unemployment (44%); (2) employment after a short SA (18%); (3) rehabilitation, recurring SA and unemployment (12%); (4) unknown sources of income (11%); (5) permanent DP after a prolonged SA (9%) and (6) temporary DP after a prolonged SA (7%).Compared with the reference cluster 2, all other clusters were associated with less employment days and having a chronic illness before the SA spell, SA based on a mental disorder and a rejected DP application during the follow-up. In addition, the clusters had some unique covariates.

CONCLUSIONS

Unemployed persons starting an SA are a heterogeneous group, with different labour market pathways. For many, the combination of unemployment and work disability means low chances for employment or regained work ability during the following years. Unemployed persons with poorer health, long history outside employment, older age, low educational level, a rejected DP application and a mental disorder could benefit from targeted support.

Health inequalities among young workers: the mediating role of working conditions and company characteristics

OBJECTIVE

Few studies have investigated health inequalities among young workers. The objectives of this study are to assess the extent of health inequalities in a sample of job starters and to explore the contribution of job demands and organisational factors.

METHODS

We analyze data from the BIBB/BAuA Youth Employment Survey 2012. The cross-sectional survey includes a representative sample of 3214 German employees, apprentices, and trainees aged 15-24 years. Individuals were grouped by their years of schooling into low (< 12 years) and high levels of education (≥ 12 years). Regression analysis estimated the link between education and four health outcomes: self-rated health, number of health events, musculoskeletal symptoms, and mental health problems over the last 12 months. Counterfactual mediation analysis tested for indirect effects of education via working conditions (i.e., physical and psychosocial job demands) and company characteristics (i.e., company size, health prevention measures, financial situation, downsizing). All analyses were adjusted for age, sex, nationality, region, working hours, job tenure, employment relationship, and economic sector.

RESULTS

Highly educated workers reported better self-rated health (b = 0.24, 95% CI 0.18-0.31) and lower numbers of health events (Rate Ratio (RR) = 0.74, 95% CI 0.67-0.82), musculoskeletal symptoms (RR = 0.73, 95% CI 0.66-0.80) and mental health problems (RR = 0.84, 95% CI 0.76-0.93). Total job demands explained between 21.6% and 87.2% of the educational differences (depending on health outcome). Unfavourable company characteristics were associated with worse health, but showed no or only small mediation effects.

CONCLUSIONS

Health inequalities are already present at the early working career due to socio-economically stratified working hazards. To enhance prevention measures that aim at reducing inequalities in workplace health, we propose shifting attention towards earlier stages of life.

Identifying labour market pathways after a 30-day-long sickness absence -a three-year sequence analysis study in Finland

BACKGROUND

Return-to-work (RTW) process often includes many phases. Still, multi-state analyses that follow relevant labour market states after a long-term sickness absence (LTSA), and include a comprehensive set of covariates, are scarce. The goal of this study was to follow employment, unemployment, sickness absence, rehabilitation, and disability pension spells using sequence analysis among all-cause LTSA absentees.

METHODS

Register data covered full-time and partial sickness allowance, rehabilitation, employment, unemployment benefits, and permanent and temporary disability pension (DP), retrieved for a 30% representative random sample of Finnish 18-59 years old persons with a LTSA in 2016 (N = 25,194). LTSA was defined as a ≥ 30-day-long full-time sickness absence spell. Eight mutually exclusive states were constructed for each person and for 36 months after the LTSA. Sequence analysis and clustering were used to identify groups with different labour market pathways. In addition, demographic, socioeconomic, and disability-related covariates of these clusters were examined using multinomial regressions.

RESULTS

We identified five clusters with emphases on the different states: (1) rapid RTW cluster (62% of the sample); (2) rapid unemployment cluster (9%); (3) DP after a prolonged sickness absence cluster (11%); (4) immediate or late rehabilitation cluster (6%); (5) other states cluster (6%). Persons with a rapid RTW (cluster 1) had a more advantaged background than other clusters, such as a higher frequency of employment and less chronic diseases before LTSA. Cluster 2 associated especially with pre-LTSA unemployment and lower pre-LTSA earnings. Cluster 3 was associated especially with having a chronic illness before LTSA. Those in cluster 4 were on average younger and had a higher educational level than others. Especially clusters 3 and 4 were associated with a LTSA based on mental disorders.

CONCLUSIONS

Among long-term sickness absentees, clear groups can be identified with both differing labour market pathways after LTSA and differing backgrounds. Lower socioeconomic background, pre-LTSA chronic diseases and LTSA caused by mental disorders increase the likelihood for pathways dominated by long-term unemployment, disability pensioning and rehabilitation rather than rapid RTW. LTSA based on a mental disorder can especially increase the likelihood for entering rehabilitation or disability pension.

Trajectories in physical functioning by occupational class among retiring women: the significance of type of retirement and social and health-related factors

BACKGROUND

Occupational class inequalities in physical functioning and their changes after retirement are poorly understood. We examined occupational class trajectories in physical functioning 10 years before and after transition to old-age and disability retirement. We included working conditions and behavioural risk factors as covariates, given their established link to health and retirement.

METHODS

We used the Helsinki Health Study cohort data from surveys 2000-2002 to 2017, and included 3901 women, who were employed by the City of Helsinki, Finland, and retired during the follow-up. Mixed-effect growth curve models were used to examine changes in RAND-36 Physical Functioning subscale (range 0-100) 10 years before and after the retirement date by occupational class.

RESULTS

Old-age (n=3073) and disability retirees (n=828) lacked class differences in physical functioning 10 years before retirement. By retirement transition, physical functioning declined and class inequalities emerged, the predicted scores being 86.1 (95% CI 85.2 to 86.9) for higher class and 82.2 (95% CI 81.5 to 83.0) for lower class old-age retirees, and 70.3 (95% CI 67.8 to 72.9) for higher class and 62.2 (95% CI 60.4 to 63.9) for lower class disability retirees. Physical functioning declined and class inequalities slightly widened among old-age retirees after the retirement, whereas among disability retirees the decline plateaued and class inequalities narrowed over time after retirement. Physical work and body mass index somewhat attenuated the class inequalities after adjustment.

CONCLUSIONS

Class inequalities in physical functioning widened after old-age retirement and narrowed after disability retirement. The examined work and health-related factors contributed weakly to the inequalities.

Austerity, economic hardship and access to medications: a repeated cross-sectional population survey study, 2013-2020

BACKGROUND

In Finland, austerity measures included an increase in medication and healthcare copayments and a decrease in many social security allowances. This study examines whether austerity coincided with an increase in socioeconomic inequality in access to medications (going short of medications because of lack of money) and whether medication access problems increased more than other forms of economic hardship (going short of food or physician visits).

METHODS

Pooled cross-sectional population surveys collected in 2013-2015, 2018 and 2020 (n=139 324) and multinomial logistic regression, with interaction between study year and economic activity (EA) (full-time work vs part-time work/retirement; old age retirement; unemployment; disability/illness; family; student), were used to estimate the effect of EA on the probability of experiencing economic hardship (no hardship/hardship including medication problems/hardship excluding medication problems) and how it varies across years.

RESULTS

Working-age adults outside full-time employment have a higher risk of economic hardship than full-time workers, and old age retirees have a lower risk. In 2018, when austerity was most pronounced, economic hardship including medication problems increased for the disabled/ill (women and men), unemployed (women) and part-time workers/retirees (men), significantly more than for full-time workers. Hardship excluding medication access problems either decreased or remained unchanged.

CONCLUSION

Austerity coincided with increasing economic hardship among vulnerable groups, thus exacerbating socioeconomic inequalities. Strengthening the role for medication access problems suggests that medication copayment increases contributed to this accumulating disadvantage.

Applications for social security benefits related to diabetes in the working age in Italy between 2009 and 2019: a nationwide retrospective cohort study

OBJECTIVES

The aim of this study is to estimate the average number of claims for social security benefits from workers with diabetes-related disability.

DESIGN

Nationwide retrospective cohort study.

SETTING

The database of the Italian Social Security Institute (INPS) was used to analyse the trends and the breakdown of all claims for social security benefit with diabetes as primary diagnosis from 2009 to 2019.

PARTICIPANTS

We selected all the applications with the 250.xx International Classification of Diseases, Ninth Revision-CM diagnosis code from 2009 to 2019.

PRIMARY AND SECONDARY OUTCOME MEASURES

The ratio between accepted or rejected claims for both ordinary incapacity benefit (OIB) and disability pension (DP) and total submitted claims over a 10-year period was computed.

RESULTS

From 2009 to 2019, 40 800 applications for social security benefits were filed with diabetes as the principal diagnosis, with an annual increase of 30% per year. Throughout the study decade, there was a higher rate of rejected (67.2%) than accepted (32.8%) applications. Among the accepted requests, most of them (30.7%) were recognised as OIB and the remaining 2.1% were recognised as DP. When related to the total number of claims presented per year, there was a 8.8% decrease of rejected applications, associated with a 20.6% increase of overall acceptance rate. In terms of time trends, the overall rise of submitted requests from 2009 to 2019 resulted in an increase in both rejected (+18%) and accepted (+61% for OIB, +11% for DP) applications. The higher rate of accepted requests was for workers aged 51-60 years, with 52% of admitted applications.

CONCLUSIONS

Between 2009 and 2019, the number of applications for social security benefits due to diabetes in Italy increased significantly, and so did the number of applications approved, mainly represented by the OIBs.

Use of Health Services and Rehabilitation before and after the Beginning of Long-Term Sickness Absence-Comparing the Use by Employment and Disability Pension Transition after the Sickness Absence in Finland

The objective of the study was to follow the health care and rehabilitation use before, during and after long-term sickness absence (LTSA), and to compare the use by post-LTSA labour market situation in terms of disability pension and employment. Individuals aged 18-58 with a ≥30-day LTSA spell in 2015 (N = 2427) were included from the total population of the city of Oulu, Finland. Register data included LTSA spells, outpatient health care visits, inpatient care spells and rehabilitation spells, disability pensions (DP), employment dates, and demographic, socioeconomic and disability-related covariates. The study population was followed for one year before, and three years after the start of LTSA. Negative binomial regression models were utilized to examine covariate-adjusted use of the three service types and group differences. The use of outpatient health care peaked at the start of the LTSA spell, and adjusted for covariates, the height of the peak was similar regardless of post-LTSA labour market situation. Adjusted for covariates, those who transferred to permanent DP after an LTSA used more outpatient (predicted mean 4.87 for attendance days quarterly, 95% CI 4.36-5.38) and inpatient (predicted mean 84 days quarterly, 95% CI 0.62-1.06) health care than others during three years after the start of LTSA. Individuals not employed after an LTSA showed the highest and increasing level of rehabilitation use. The results indicate that Individuals returning to employment after an LTSA are provided with relatively high amount of early outpatient care, possibly aiding the return. For individuals not employed after an LTSA, rehabilitation is used quite frequently but rather late in the disability process. The frequent use of health care among future disability pensioners is consistent with their increasing health problems leading to retirement.

Outpatient healthcare use before and during a long-term sickness absence spell: a register-based follow-up study comparing healthcare use by the length of sickness absence and transition to disability pension in Finland

OBJECTIVES

The objective of the study was to examine outpatient healthcare use before and during a long-term sickness absence (LTSA), and to compare the development of healthcare use between groups defined through LTSA lengths and disability pension (DP) transition.

DESIGN

Register-based longitudinal study with five 6-month periods before and after the start of the LTSA spell in early 2016.LTSA groups 1 (N=210) and 2 (N=187) went on to reach the statutory maximum LTSA length, with group 1 transitioning to DP. Group 3 (N=3082) had a shorter LTSA spell. Control group 4 (N=92 921) had no LTSA.

SETTING AND PARTICIPANTS

Non-retired individuals aged 20-59, with no LTSA during 2015 (N=96 400) were included from the total population of the city of Oulu, Finland. Register data were linked on LTSA spells and outpatient healthcare use 2013-2018, DP status in 2018, and various covariates.

MAIN OUTCOME MEASURES

Negative binomial regression models were used to examine the covariate-adjusted number of healthcare visits, and to examine the association of the LTSA groups with healthcare use before and after the start of LTSA (incidence rate ratios and predicted means).

RESULTS

Individuals eventually reaching the maximum LTSA length (groups 1 and 2) had a higher level of healthcare use before the LTSA and especially after the start of LTSA than others. Individuals transferring to DP after the maximum LTSA (group 1) used healthcare the most after the start of LTSA.

CONCLUSIONS

The risk for at least 1 year's disability may be identified by frequent outpatient healthcare use years before LTSA. However, future disability retirees could not be identified through their pre-LTSA healthcare use. Instead, their high use of healthcare after the start of the LTSA was consistent with their increasing health problems leading to retirement.

Disability insurance benefit application in Switzerland: an analysis of linked administrative and survey data

Background

The guiding principle of disability insurance in Switzerland is ‘rehabilitation before pension’. Access to rehabilitation measures to restore, maintain or improve the earning capacity of individuals with disabilities is essential. Gainful employment enables them to be an active part of society, improves their quality of life, and may mitigate the adverse health effects of disability pension receipt. The aim of this study was therefore to identify factors for disability insurance benefit application in Switzerland.

Methods

A novel dataset was created linking the 2010 Social Protection and Labour Market cross-section with administrative register data on disability insurance benefit application (2009–2018). Multiple logistic regression was employed to examine the associations between long-term health-related activity limitation, region of residence, demographic and socioeconomic characteristics and disability insurance benefit application in adults aged 18–55 (N = 18,448). Sensitivity analysis based on age was performed in individuals aged 18 to retirement age and aged 25 to 55.

Results

The regression results showed higher odds of disability insurance benefit application for individuals suffering from long-term health-related activity limitations (OR 2.88; 95% CI 1.29–6.44; p-value 0.010); born outside of Switzerland (OR 1.75; 95% CI 1.32–2.32; p-value 0.000); living without a working partner (OR 1.54; 95% CI 1.17–2.02; p-value 0.002); living without a child aged 0–14 years (OR 1.70; 95% CI 1.29–2.26; p-value 0.000); aged 18–39 (OR 1.41; 95% CI 1.09–1.83; p-value 0.009); with a learnt occupation in ‘Manufacturing’ (OR 2.75; 95% CI 1.68–4.50; p-value 0.000), ‘Construction and mining’ (OR 2.03; 95% CI 1.13–3.66; p-value 0.018), ‘Trade and transport’ (OR 2.12; 95% CI 1.30–3.45; p-value 0.003), ‘Business and administration’ (OR 1.68; 95% CI 1.03–2.72; p-value 0.036), and ‘Health, teaching, culture and science’ (OR 1.55; 95% CI 1.05–2.29; p-value 0.026); and renters (OR 1.44; 95% CI 1.00–1.94; p-value 0.016). The results were robust to alternative samples defined by age – albeit with some differences in regional and learnt occupational patterns.

Conclusions

The results suggested that disability insurance benefit application is more than a health-related phenomenon in Switzerland. However, the results provided a less consistent picture on the role of marginalization in application than in other European countries.

Work Participation among Women and Men in Sweden: A Register Study of 8.5 Million Individuals

Observational research studies from various countries suggest that women's working patterns across the life course are often fragmented compared to men's. The aim of our investigation was to use nationwide register data from Sweden to examine the extent to which generation and time of entry to the work force explain the sex differences in work participation across the life course. Our analyses were based on individual-level data on 4,182,581 women and 4,279,571 men, who were 19-69 years old and resident in Sweden in 1995, 2000, 2005, 2010, or 2015. Data on income and number of net days on disability pension, obtained from multiple linked registers, were used to ascertain each individual's main activity (in paid work, on disability pension, and not in paid work) each year. Years in paid work and on disability pension were calculated as the sums of years spent in either of these states from age 19 to 69 years. We used negative binomial regression to model the associations of generation and baseline year with years in paid work and years on disability pension. All models were run separately for women and men, with the duration of follow-up constrained to one, to account for the different follow-up times between individuals. Overall, the number of years in paid work across the life course was larger among men than women, and men entered into the workforce earlier. The difference between women and men was similar across generations and time periods. Adjustment for education, income, number of children aged <18 years living at home, country of birth, and the type of residential area had minimal impact on the estimates. Our findings suggest that women spend fewer years in paid work across the life course than men, highlighting the need for continued efforts to close the gender gap in work participation.

Sickness Absence and Disability Pension in the Very Long Term: A Finnish Register-Based Study With 20 Years Follow-Up

Sickness allowance is paid for short-term sickness absence and is thus an indicator of temporary ill health, but it is also associated with a heightened risk of receiving disability pension. Using event history analysis, we examined the long-term risk for disability pension receipt after first observed receipt of medically certified sickness allowance in each single year after sickness allowance was first recorded. Utilizing longitudinal data from the Finnish population register, covering the period 1989-2010, we observed 110,675 individuals aged 16-40 years at baseline. Using discrete-time hazard models, we estimated how the first observed receipt of sickness allowance was related to the risk of receiving disability pension, with an average follow-up time of 20.6 years. In this population, about 40 percent received sickness allowance and 10 percent received disability pension. In the first years after sickness allowance receipt, there was a substantial difference between long-term and short-term sickness allowance recipients in the hazard of becoming a disability pensioner. This difference levelled out over time, but even 20 years after the first observed sickness allowance receipt, the hazard of disability retirement was more than 15 times higher than that of non-recipients of sickness allowance. Patterns were similar for men and women. First observed receipt of sickness allowance is a powerful predictor for disability pension receipt, also in the very distant future. Thus, it can be used to monitor people with heightened risk of becoming more permanently ill and falling outside the labour market.

Consumption of psychotropic drugs among disability pension applicants with mental disorders: comparing awarded and rejected applicants in Finland

PURPOSE

Psychotropic drug consumption as a proxy measure of mental health problems during a disability pension process has only been studied among awarded applicants. This study examined psychotropic drug purchase trajectories among awarded and rejected disability pension applicants. Analyses were conducted in different diagnostic and sociodemographic groups.

METHODS

A representative 70% sample of Finnish adults applying for disability pension due to a mental disorder in 2009-2011 (N = 18,087) was followed for 4 years in 3-month periods both before and after the pension decision. Register data on purchased drugs measured in defined daily doses (DDDs), gender, age, occupational class, unemployment history, and diagnostic group were used. The DDD levels and trends were analyzed using growth curve models.

RESULTS

Psychotropic drug purchases increased before the pension decision and decreased gradually thereafter among both awarded and rejected applicants. The average DDD level was higher for rejected than awarded applicants before the decision but lower thereafter. The high pre-decision level for rejected applicants was explicit with a lower socioeconomic status. The pre-decision increase in DDDs was steeper for awarded applicants. Changes in DDDs before and after the decision were most prominent for depression, bipolar disorders, schizophrenia, and anxiety disorders.

CONCLUSION

Awarded and rejected disability pension applicants differed partly in their trajectories of psychotropic drug consumption. For awarded applicants, the steep rise of consumption prior to the award possibly reflects worsening occupational capacity. Early high consumption for rejected applicants signals long running mental health problems and calls for earlier support.

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.
