Interrelationships between education, occupational class and income as determinants of sickness absence among young employees in 2002-2007 and 2008-2013

BackgroundA low socioeconomic position (SEP) is consistently associated with ill health, sickness absence (SA) and permanent disability, but studies among young employees are lacking. We examined the interrelationships between education, occupational class and income as determinants of SA among 25-34-year-old employees. We also examined, whether the association between SEP and SA varied over time in 2002–2007 and 2008–2013.MethodsThe analyses covered young, 25-34-year-old women and men employed by the City of Helsinki over the time periods 2002–2007 and 2008–2013. Four-level education and occupational class classifications were used, as well as income quartiles. The outcome measure was the number of annual SA days.ResultsEducation had the strongest and most consistent independent association with SA among women and men in both periods under study. Occupational class had weaker independent and less consistent association with SA. Income had an independent association with SA, which strengthened over time among the men. The interrelationships between the SEP indicators and SA were partly explained by prior or mediated through subsequent SEP indicators. Socioeconomic differences followed only partially a gradient for occupational class and also for income among men.ConclusionsPreventive measures to reduce the risk of SA should be considered, especially among young employees with a basic or lower-secondary education.

Educational differences in sickness absence trends among young employees from 2002 to 2013 in Helsinki, Finland

Objective Socioeconomic differences in sickness absence (SA) are well established among older employees but poorly understood among the young. Our aim was to examine 12-year trends in educational differences in SA among young female and male employees, and to assess the magnitude of the differences. Design We examined annual SA spells. The data were obtained from the employers registers and linked to Statistics Finlands register data on completed education and qualifications. Education was classified into four hierarchical groups. Joinpoint regression models were used to identify turning points in SA trends. The magnitude of the relative educational differences was estimated in accordance with the relative index of inequality for 2002, 2008 and 2013. Setting Employees of the City of Helsinki, Finland, in 2002–2013. Participants The analyses covered female and male employees aged 25–34 years: employees aged 35–54 years were used as a reference group. Outcome SA spells. Results An educational gradient emerged among younger and older women and men. SA spells increased in the early 2000s, and downward turning points were located in 2007–2010 in all educational groups among women and in most groups among men. The magnitude of the differences remained broadly stable among younger women from 2002 to 2013, and decreased slightly among older women and more strongly among younger and older men. The educational differences were greater among men than women in the early 2000s, but similar among both at the end of the study period. Conclusions The changes in SA spells may reflect the economic downturn started in 2008 and resulting job insecurity. Early preventive measures aimed at reducing educational differences in SA should be focused at an early stage on those with low levels of education in particular.

Educational differences in disability retirement among young employees in Helsinki, Finland.

BACKGROUND Disability retirement (DR) among young employees is an increasing problem affecting work life and public health, given the potential major loss of working time. Little is known about educational differences in the risk of DR among young employees, despite the need for such knowledge in targeting preventive measures. We examined the association between education and DR due to any cause and to mental and non-mental causes among young employees. METHODS Personnel register data of the City of Helsinki from the years 2002-2013 for 25-to-34-year-old employees (n= 41225) were linked to register data from the Finnish Centre for Pensions on DR (n= 381), and from Statistics Finland on education. Education was categorised into four hierarchical groups. The mean follow-up time was 5.7 years. Cox regression analysis was used. RESULTS There were 381 DR events and of the events, over 70% were due to mental disorders and 72% were temporary. A consistent educational gradient was found. Those with a basic education were at the highest risk of DR due to any cause (HR 4.64, 95% CI 3.07, 7.02), and to mental (HR 4.79, 95% CI 2.89, 7.94) and non-mental causes (HR 4.32, 95% CI 2.10, 8.91). CONCLUSIONS DR due to any cause, and to mental and non-mental causes, followed a clear educational gradient. Early intervention, treatment and rehabilitation with a view to maintaining work ability are needed among young employees, especially those with low education. Adapting working conditions to their health and work ability may also help to avoid premature exit from work.

10-Year Trends of Educational Differences in Long Sickness Absence Due to Mental Disorders

Mental disorders are a key cause of sickness absence (SA) and challenge prolonging working careers. Thus, evidence on the development of SA trends is needed. In this study, educational differences in long SAs due to mental disorders were examined in two age groups among employees of the City of Helsinki from 2004 to 2013.

The Magnitude of Occupational Class Differences in Sickness Absence: 15-Year Trends among Young and Middle-Aged Municipal Employees

Background: Our aim was to examine the magnitude of relative occupational class differences in sickness absence (SA) days over a 15-year period among female and male municipal employees in two age-groups. Methods: 18–34 and 35–59-year-old employees of the City of Helsinki from 2002 to 2016 were included in our data (n = ~37,500 per year). Occupational class was classified into four groups. The magnitude of relative occupational class differences in SA was studied using the relative index of inequality (RII). Results: The relative occupational class differences were larger among older than younger employees; the largest differences were among 35–59-year-old men. Among women in both age-groups the relative class differences remained stable during 2002–2016. Among younger and older men, the differences were larger during the beginning of study period than in the end. Among women in both age-groups the RII values were between 2.19 (95% confidence intervals (CI) 1.98, 2.42) and 3.60 (95% CI 3.28, 3.95). The corresponding differences varied from 3.74 (95% CI 3.13, 4.48) to 1.68 (95% CI 1.44, 1.97) among younger and from 6.43 (95% CI 5.85, 7.06) to 3.31 (95% CI 2.98, 3.68) among older men. Conclusions: Relative occupational class differences were persistent among employees irrespective of age group and gender. Preventive measures should be started at young age.

Socioeconomic differences in health check-ups and medically certified sickness absence: a 10-year follow-up among middle-aged municipal employees in Finland

Background There is contradictory evidence on the association between health check-ups and future morbidity. Among the general population, those with high socioeconomic position participate more often in health check-ups. The main aims of this study were to analyse if attendance to health check-ups are socioeconomically patterned and affect sickness absence over a 10-year follow-up. Methods This register-based follow-up study included municipal employees of the City of Helsinki. 13 037 employees were invited to age-based health check-up during 2000–2002, with a 62% attendance rate. Education, occupational class and individual income were used to measure socioeconomic position. Medically certified sickness absence of 4 days or more was measured and controlled for at the baseline and used as an outcome over follow-up. The mean follow-up time was 7.5 years. Poisson regression was used. Results Men and employees with lower socioeconomic position participated more actively in health check-ups. Among women, non-attendance to health check-up predicted higher sickness absence during follow-up (relative risk =1.26, 95% CI 1.17 to 1.37) in the fully adjusted model. Health check-ups were not effective in reducing socioeconomic differences in sickness absence. Conclusions Age-based health check-ups reduced subsequent sickness absence and should be promoted. Attendance to health check-ups should be as high as possible. Contextual factors need to be taken into account when applying the results in interventions in other settings.

Self-Certified Sickness Absence among Young Municipal Employees-Changes from 2002 to 2016 and Occupational Class Differences

We examined changes in self-certified, one-to-three day sickness absence (SA) among young employees from 2002 to 2016 and the magnitude of occupational class differences during that period. All 18–34-year-old employees of the City of Helsinki, Finland were included (2002–2016, n = ~11,725 per year). Employer’s personnel and SA registers were used. Occupational class was categorized to four groups. Changes in self-certified SA from 2002 to 2016 were analyzed with Joinpoint regression and the magnitudes of occupational class differences were estimated with the relative index of inequality (RII). Most of the trends first increased and turned to decrease in 2007/2010. Managers and professionals had the least amount of SA, but steadily increasing trends were observed among men. Self-certified SA followed only partially the typical socioeconomic gradient, as routine non-manuals had the highest levels of SA. The magnitude of occupational class differences in self-certified SA was stable during the study period only among women. Self-certified SA and occupational class differences have increased in recent years among men in the lower occupational classes. Socioeconomic differences exist in self-certified SA among young employees, but gradient is only partial. Overall, high amounts of self-certified SA especially in the lower occupational classes require further studies and preventive measures.
