Sustainable Working Life Patterns in a Swedish Twin Cohort: Age-Related Sequences of Sickness Absence, Disability Pension, Unemployment, and Premature Death during Working Life
- 2022

Tidskriftsartikel (refereegranskat)abstract
- We aimed to investigate sustainable working life via age-related sequences of sickness absence (SA), disability pension (DP), unemployment (UE), premature death, and the influence of individual characteristics, accounting for familial confounding. The sample included monozygotic (MZ) and dizygotic (DZ) same-sexed twin pairs with register data (n = 47,450) that were followed for 10 years in four age cohorts: 26–35 (n = 9892), 36–45 (n = 10,620), 46–55 (n = 12,964) and 56–65 (n = 13,974). A sequence analysis was done in a 7-element state space: 1. “Sustainable working life”: SA/DP 0–30 days and UE 0–90 days; 2. “Unemployment >90 days”: SA/DP 0–30 days and UE > 90 days; 3. “Moderate SA/DP”: SA/DP 30–180 days; 4. “Almost full year of SA/DP”: SA/DP 180–365 days; 5. “Full year of SA/DP”: SA/DP ≥ 365 days; 6. Death; 7. Old-age pension. The largest cluster had a sustainable working life and never experienced states 2–6 (34–59%). Higher education and being married predicted a lower likelihood of experiencing states 2–6. The MZ twin pairs (vs. DZ) were more often in the same cluster suggesting the role of genetic factors. To conclude, the sustainable working life was the largest cluster group. Few individuals had prolonged periods of interruptions of sustainable working life meriting actions, especially in early adulthood for interventions to support workability.

Sustainable Working Life in a Swedish Twin Cohort-A Definition Paper with Sample Overview
- 2021
-
Ingår i: International journal of environmental research and public health. - : MDPI AG. - 1660-4601. ; 18:11

Tidskriftsartikel (refereegranskat)abstract
- Background: A unified or consensus definition of “sustainable working life” remains lacking, although studies investigating risk factors for labour market exit are numerous. In this study, we aimed (1) to update the information and to explore a definition of “sustainable working life” via a systematic literature review and (2) to describe the working life trajectories via the prevalence of sickness absence (SA), disability pension (DP), and unemployment in a Swedish twin cohort to provide a sample overview in our Sustainable Working Life-project. Methods: A systematic literature review was conducted to explore the studies with the search phrase “sustainable working life” in PubMed, PsycInfo, and the Web of Science Database of Social Sciences in January 2021, resulting in a total of 51 references. A qualitative synthesis was performed for the definitions and the measures of “sustainable working life.” Based on the Swedish Twin project Of Disability pension and Sickness absence (STODS), the current dataset to address sustainable working life includes 108 280 twin individuals born between 1925 and 1990. Comprehensive register data until 2016 for unemployment, SA and DP were linked to all individuals. Using STODS, we analysed the annual prevalence of SA, DP, and unemployment as working life trajectories over time across education and age groups. Results: The reviewed 16 full articles described several distinct definitions for sustainable working life between 2007 and 2020 from various perspectives, i.e., considering workplaces or employees, the individual, organizational or enterprise level, and the society level. The definition of “sustainable working life” appearing most often was the swAge-model including a broad range of factors, e.g., health, physical/mental/psychosocial work environment, work motivation/satisfaction, and the family situation and leisure activities. Our dataset comprised of 81%–94% of individuals who did not meet SA, DP, or unemployment during the follow-up in 1994–2016, being indicative for “sustainable working life.” The annual prevalence across years had a decreasing trend of unemployment over time, whereas the prevalence of SA had more variation, with DP being rather stable. Both unemployment and DP had the highest prevalence among those with a lower level of education, whereas in SA, the differences in prevalence between education levels were minor. Unemployment was highest across the years in the youngest age group (18–27 years), the age group differences for SA were minor, and for DP, the oldest age group (58–65 years) had the highest prevalence. Conclusions: No consensus exists for a “sustainable working life,” hence meriting further studies, and we intend to contribute by utilising the STODS database for the Sustainable Working Life project. In the upcoming studies, the existing knowledge of available definitions and frameworks will be utilised. The dataset containing both register data and self-reports enables detailed follow-up for labour market participation for sustainable working life.

- Aims: In Sweden, the Social Insurance Offices each year refer long-term sickness absentees to comprehensive investigations to clarify medical conditions. However, there is a lack of scientific knowledge about these patients and their morbidity. The aim was to characterize a population of these sickness absentees regarding prevalence of somatic and psychiatric diagnoses and possible associations with sociodemographic, lifestyle, and health characteristics. Methods: A cross-sectional study was made up of 635 sickness absentees below the age of 64, who the local Social Insurance Offices in Stockholm County, Sweden, referred to a special unit for multidisciplinary investigation. Data was obtained from questionnaires and medical records. The patients were examined by board certified specialists in psychiatry, orthopaedic surgery, and rehabilitation medicine. Relative risks were estimated by use of modified Poisson regression to assess the associations between characteristics and diagnose outcomes. Results: About 80% of the patients had more than one diagnosis. The vast majority had a psychiatric diagnosis, and approximately 55% had that in combination with at least one somatic diagnosis. An increased risk for being given a psychiatric diagnosis was found for men and unemployed people. In addition, lack of social life and friends and self-reported mental health problems were associated with psychiatric diagnoses but also among those who were given somatic diagnoses in combination with psychiatric diagnoses. Increased risks for somatic diagnoses were found for women and for patients with a higher education. Conclusions: Long-term sickness absentees referred to multidisciplinary investigations display high co-morbidity of psychiatric and somatic diagnoses and are a heterogeneous group with diverse sociodemographic and medical characteristics.

Tidskriftsartikel (refereegranskat)abstract
- PurposeThe incidence of disability pension (DP), especially due to mental diagnoses, has increased in many countries, but knowledge of socio-demographic risk factors for DP is limited. Further, the influences of genetics and early-life factors (jointly called familial factors) on these associations remain to be studied. The aims were to study incidence of DP (due to all and mental diagnoses) and associations with socio-demographic factors, and also to establish whether associations differ with DP diagnosis and sex, and are influenced by familial factors.MethodsA prospective cohort study of all twins born in 1928–1958 (n = 52,609) in Sweden was conducted. The twins were followed from 1993 to 2008 regarding DP. Cox proportional hazard models were applied.ResultsThe cumulative incidence of DP was 17 %. Of all the DP diagnoses 20 % were mental. Higher age (≥45 years), being a woman or unmarried, and/or living in a semi-urban area were risk factors for DP. Low education, being a blue-collar worker or being self-employed predicted either higher (all diagnoses) or lower (mental diagnoses) risk of DP. Rural areas were associated with DP due to mental diagnoses. The estimates varied for men and women. After adjustment for familial factors the associations of DP with education and marital status were attenuated and no longer significant. Similar results were apparent for DP due to mental diagnoses and socioeconomic status.ConclusionsFamilial factors may select individuals into some of the established risk environments for DP. Studies investigating the causes of DP need to take such confounding into account.

- Work incapacity is a major public health challenge and an economic burden to both society and individuals. Understanding the underlying causes is becoming ever more relevant as many countries face an aging workforce. We examined stability and change in genetic and environmental factors influencing work incapacity from age 18 until retirement, and sex differences in these effects. The large population-based sample comprised information from 28,759 twins followed for up to 23 years combined with high-quality national registry data. We measured work incapacity as the total proportion of potential workdays lost due to sickness absence, rehabilitation and disability benefits. Structural equation modeling with twin data indicated moderate genetic influences on work incapacity throughout life in both men and women, with a high degree of genetic stability from young to old adulthood. Environmental influences were mainly age-specific. Our results indicate that largely the same genetic factors influence individual differences in work incapacity throughout young, middle and older adulthood, despite major differences in degree of work incapacity and probable underlying medical causes.
