Chronic health conditions and work ability in the ageing workforce: the impact of work conditions, psychosocial factors and perceived health

The use of individual and collective selection, optimisation and compensation (SOC) strategies and their association with work ability among senior workers

Background Selection, optimisation, and compensation (SOC) can be important strategies for maintaining work ability as we age. This study aimed to explore differences in self-reported individual and collective use of SOC strategies across job functions, as well as their association with self-rated work ability.

METHODS

In the third wave of the SeniorWorkingLife study, 10,798 workers aged 50 + , across the job function categories "Office work", "work with people", and "work in the field of production", replied to questions about collective and individual SOC strategies and work ability. Using multiple regression, we modelled associations between SOC and work ability.

RESULTS

Associations between SOC and work ability were generally weaker among participants working in the field of production. Both individual and collective use of selection had much weaker associations with work ability in the job functions "office work" and "working with people". In the job function "working in the field of production", only collective compensation was positively associated with work ability while individual selection was significantly but negatively associated with work ability.

CONCLUSIONS

The use of SOC may be particularly beneficial for older employees working with people. Optimisation and compensation may be the most important SOC strategies for maintaining the work ability of older employees working with people and doing office work. For older employees working in the field of production, collective optimisation may support the maintenance of work ability while reduced work ability may be associated with the use of individual selection as a "coping strategy".

Predicting the work ability of security guards at a university in Nakhon Si Thammarat province, Thailand

Objectives. The number of security guards in universities has increased significantly. This study aimed to predict work ability of university security guards. Methods. A cross-sectional study of 97 university security guards in Thailand was performed. Data were collected through interviews using a questionnaire covering social demographics, behavioral health and work ability. The data were analyzed using χ2 tests and logistic regression models. Results. The average work ability index (WAI) score was 38.1 ± 3.8, with 65.0% of participants scoring 'good'. Social support significantly influenced the WAI (p = 0.004). Those with insufficient support were 4.3 times more likely to show poor work ability. Mental health also impacted the WAI (p = 0.006); those with poor mental health were 4.7 times at risk. Additionally, work experience affected the WAI (p = 0.039). Those with ≥5 years of experience showed reduced work ability compared to their less-experienced counterparts (adjusted odds ratio 0.4; 95% confidence interval [0.20, 0.96]). Conclusions. Supervisors should provide social support and offer rewards and commendations to enhance employees' abilities, health behaviors and management of underlying diseases. Additionally, organizations should prioritize health and safety in the workplace to ensure their employees are healthier and perform their tasks more effectively.

Importance of an Integrated Assessment of Functional Disability and Work Ability in Workers Affected by Low Back Pain

Background

This study examines the relationship between functional disability and work ability in workers affected by low back pain (LBP) through an analysis of correlations between the Oswestry Disability Index (ODI) and Work Ability Index (WAI). The role of personal and work factors on functional disability/work ability levels has also been studied. LBP is the most common musculoskeletal problem and a major disabling health problem worldwide. Its etiology is multifactorial. Multidisciplinary approaches may help reduce the burden of pain and disability and improve job continuity and reintegration at work.

Methods

A cohort of 264 patients affected by LBP from an Italian outpatient clinic were included in a clinical diagnostic/therapeutic trial aiming at rehabilitation and return to work through an integrated investigation protocol. Data were collected during the first medical examination using anamnestic and clinical tools. The final sample is composed of 252 patients, 57.1% man, 44.0 % blue collars, 46.4% with the high school degree, 45.6% married.

Results

WAI and ODI reported a negative and fair correlation (r = -0.454; p = .000). Workers with acute LBP symptoms have a higher probability of severe disability than those with chronic LBP symptoms. White collars without depressive symptoms reported higher work ability - even in chronic disability conditions-than those with depressive symptoms.

Conclusion

The study found that ODI and WAI have a convergent validity and this suggests that the two tools measure capture distinctive aspects of disability related to personal, environmental, and occupational characteristics. The most important and modifiable prognostic factors found for ODI and WAI were depressive symptoms, workday absence, and intensity of back pain. The study also found a mild association between age and ODI. The study's findings highlight the importance of using a multidisciplinary approach to manage and prevent disability due to LBP.

Effects of declines in personal mastery on self-perceived mobility, physical function, cognitive function, and depressive symptoms: a 6-year follow-up study from the Social Environment and Biomarkers of Aging Study

OBJECTIVES

As the psychosocial competence, personal mastery helps individuals to cope with stressful life events, and this study aims to examine impacts of declines in personal mastery on healthy aging among community-dwelling middle-aged and older adults using a nationally representative cohort.

METHODS

Data from 648 study participants in the Social Environment and Biomarkers of Aging Study (SEBAS) were retrieved for analysis. All participants were divided into four groups based on their baseline and changes of personal mastery (measured by the Pearlin mastery score) during the 6-year follow-up. Multivariate logistic regression models were adopted to examine associations between declines in personal mastery and indicators for healthy aging (declines in self-perceived mobility, physical function (activities of daily living (ADLs) and instrumental activities of daily living (IADLs)), cognitive function and depressive symptoms).

RESULTS

After adjustments for demographics and comorbidities, those with declines in personal mastery were associated with greater risks of declines in self-perceived mobility (adjusted odds ratio (aOR) 1.50 [95% confidence interval 1.01-2.22], p < 0.05). Although the point estimate in the unadjusted models indicated similar associations between declines in personal mastery and declines in ADLs, IADLs, cognitive function or depressive symptoms, these outcomes did not reach statistical significance in the adjusted model.

CONCLUSIONS

Declines in personal mastery were negatively associated with indicators related to healthy aging (particularly locomotion) in a 6-year follow-up. Further investigations are needed to explore the effects of preventing declines in personal mastery in promoting healthy aging over time.

A prospective cohort study of presenteeism and poverty among Japanese workers during the COVID-19 pandemic

Objectives

This study examined the association of presenteeism with experiences of poverty among Japanese workers during the COVID‐19 pandemic.

Methods

A prospective cohort study of Japanese workers was conducted using an Internet monitoring survey. The baseline survey was conducted in December 2020, and a follow‐up survey in December 2021. Of the 27 036 workers who participated, 18 560 (68.7%) completed the follow‐up survey. The 11 081 who reported that they were not in financial difficulty in the baseline survey were included in the analysis. The degree of work functioning impairment was assessed at baseline using the Work Functioning Impairment Scale (WFun). Households' experience of not being able to pay for food and clothing was identified in the follow‐up survey. The odds ratios (ORs) of presenteeism determined by WFun associated with poverty were estimated using a multilevel logistic model. The multivariate model included age, sex, marital status, job type, income, education, smoking, alcohol consumption, number of employees in the workplace, and the incidence rate of COVID‐19 by prefecture at baseline.

Results

In the multivariate model, the odds ratio of experiencing food insecurity increased with high WFun score: compared with WFun scores of 13 or less, the OR was 1.87 (95% CI: 1.43–2.43, P < .001) for WFun scores of 14 or more and 3.26 (95% CI: 2.58–4.12, P < .001) for WFun scores of 21 or more.

Conclusions

In addition to labor productivity, the adverse effects of presenteeism on social security‐related concerns such as poverty require further attention.

Therapists' experiences and needs with regard to providing work-focused care: a focus group study

BACKGROUND

Musculoskeletal disorders (MSDs) can create a temporary or permanent disability that reduce a person's ability to work. Physiotherapists (PTs), occupational therapists (OTs) and exercise therapists (ETs) are often involved in the early management of MSDs. There is a need for additional insights into therapists' experiences, barriers and needs to work-focused care. Moreover, there is no evidence on how OTs and ETs address work participation. Therefore, the aim of this qualitative study was 1) to investigate how generalist PTs, OTs and ETs provide work-focused healthcare and 2) to obtain insight into their perceived barriers and needs that affect their ability to address occupational factors.

METHODS

An exploratory qualitative study using three focus groups. Generalist PTs, OTs and ETs were eligible to participate if they treated working patients with MSDs. A semi-structured interview guide with open-ended questions was developed. Two moderators facilitated each focus group using the interview guide, and all the groups were audio recorded. Data were analysed using inductive thematic analysis.

RESULTS

Sixteen therapists (mean age 44 years, range 25-59) participated in this study. Participants were aware of the importance of taking occupational factors into account. Whether they address occupational factors is largely dependent on the patient's request for help. However, ETs and OTs consider it normal to ask about occupational factors during the diagnostic process, while PTs often address this in later consultations. Almost all participants were unaware of the existence of PTs, OTs or ETs who are specialised in occupational health. Moreover, almost all participants struggled with when to refer a patient to other (occupational) healthcare professionals. This study identified several needs of therapists. These included knowledge about laws and legislation and skills for identifying and addressing work-related or work-relevant complaints.

CONCLUSIONS

Participants in this qualitative study were aware of the importance of taking occupational factors into account. However, how PTs, OTs and ETs address work participation and the extent to which they do so can be improved. There was a lack of knowledge about and cooperation with occupational health professionals, including PTs, OTs or ETs specialised in occupational health.

Do Menopausal Symptoms Affect the Relationship between Job Demands, Work Ability, and Exhaustion? Testing a Moderated Mediation Model in a Sample of Italian Administrative Employees

(1) Background: The increasing presence of employed women undergoing menopause has stimulated a growing corpus of research highlighting the complex relationship between menopause and work. Nevertheless, little is known regarding the mechanism by which menopause affects work ability and work-related well-being. In order to fill this gap in the literature, the present study examines whether and how menopausal symptoms affect the relationship between job demands, work ability, and exhaustion. (2) Method: In total, 1069 menopausal women, employed as administrative officers in a public organization, filled out a self-report questionnaire. A moderated mediation analysis was carried out using the latent moderated structural (LMS) equation. (3) Findings: The findings of this analysis indicate that the indirect effect of work ability on the relationship between job demands and exhaustion is influenced by the exacerbating effect of menopausal symptoms on the relationship between job demands and work ability. Moreover, the conditional effect confirmed that women with high menopausal symptoms receive more exposure to the negative effects of job demands on work ability compared to women with low menopausal symptoms. (4) Conclusion: The present findings may help in addressing interventions to prevent negative outcomes for menopausal women and their organizations.

Self-Reported Variables as Determinants of Upper Limb Musculoskeletal Symptoms in Assembly Line Workers

BACKGROUND

Assembly lines work is frequently associated to work-related upper limb musculoskeletal disorders. The related disability and absenteeism make it important to implement efficient health surveillance systems. The main objective of this study was to identify self-reported variables that can determine work-related upper limb musculoskeletal symptoms-discomfort/pain-during a 6-month follow-up.

METHODS

This was a prospective study with a 6-month follow-up period, performed in an assembly line. Upper limb musculoskeletal discomfort/pain was assessed through the presence of self-reported symptoms. Uni- and multivariate logistic regression analyses were used to evaluate which self-reported variables were associated to upper limb symptoms after 6 months at the present and to upper limbs symptoms in the past month.

RESULTS

Of the 200 workers at baseline, 145 replied to the survey after 6 months. For both outcomes, "having upper limb symptoms during the previous 6 months" and "education" were possible predictors.

CONCLUSION

Our results suggest that having previous upper limb symptoms was related to its maintenance after 6 months, sustaining it as a specific determinant. It can be a hypothesis that this population had mainly workers with chronic symptoms, although our results give only limited support to self-reported indicators as determinants for upper limb symptoms. Nevertheless, the development of an efficient health surveillance system for high demanding jobs should implicate self-reported indicators, but also clinical and work conditions assessment should be accounted on the future.

Health-related Work Limitations Among Older Workers-the Role of Flexible Work Arrangements and Organizational Climate

BACKGROUND AND OBJECTIVES

Given their increasing prevalence with age, chronic health conditions (CHCs) are substantially affecting older workers and organizations. An important question is whether and how flexible work arrangements and organizational climates may help to reduce the work limitations experienced by older workers. Grounded on the Job Demand-Resource model, we hypothesize that access to flexible work arrangements (working-time flexibility, workplace flexibility, phased retirement) and supportive organizational climates (healthy ageing climate, psychological safety climate) are vital job resources that are associated with fewer health-related work limitations among older workers experiencing CHCs.

RESEARCH DESIGN AND METHODS

Multilevel data were collected among 5,419 older workers (60-65 years) in 624 organizations in the Netherlands. Perceived health-related work limitations of older workers diagnosed with arthritis (N = 2,330), cardiovascular disease (N = 720), and sleep disorders (N = 816) were analyzed.

RESULTS

Multilevel ordered logistic regression analyses revealed that perceived access to flexible working hours and a psychologically safe organizational climate was associated with fewer health-related work limitations among older workers with CHCs.

DISCUSSION AND IMPLICATIONS

Facilitating longer working lives is a key policy challenge within organizations, in particular if older workers are constraint by CHCs. This study shows that offering flexible working hours and ensuring a psychologically safe climate, where older workers with health issues are inclined to share their work needs and preferences, are likely to contribute to healthy ageing in the workplace.

The associations between late effects of cancer treatment, work ability and job resources: a systematic review

Objective

The aim of this review is to evaluate associations between possible late effects of cancer treatment (i.e. physical complaints, fatigue, or cognitive complaints) and work ability among workers beyond 2 years after cancer diagnosis who returned to work. The role of job resources (social support, autonomy, leadership style, coaching, and organizational culture) is also evaluated.

Methods

The search for studies was conducted in PsycINFO, Medline, Business Source Premier, ABI/Inform, CINAHL, Cochrane Library and Web of Science. A quality assessment was used to clarify the quality across studies.

Results

The searches included 2303 records. Finally, 36 studies were included. Work ability seemed to decline shortly after cancer treatment and recover in the first 2 years after diagnosis, although it might still be lower than among healthy workers. No data were available on the course of work ability beyond the first 2 years. Late physical complaints, fatigue and cognitive complaints were negatively related with work ability across all relevant studies. Furthermore, social support and autonomy were associated with higher work ability, but no data were available on a possible buffering effect of these job resources on the relationship between late effects and work ability. As far as reported, most research was carried out among salaried workers.

Conclusion

It is unknown if late effects of cancer treatment diminish work ability beyond two years after being diagnosed with cancer. Therefore, more longitudinal research into the associations between possible late effects of cancer treatment and work ability needs to be carried out. Moreover, research is needed on the buffering effect of job resources, both for salaried and self-employed workers.

The moderating role of psychosocial working conditions on the long-term relationship between depressive symptoms and work ability among employees from the Baby Boom generation

Objective

Mental disorders have been identified as a leading cause for reduced work ability in industrialized countries. Identification of workplace factors that can increase the work ability of employees with depressive symptoms from the Baby Boom generation is, therefore, highly relevant. This study thus aims to investigate whether changes in psychosocial working conditions can moderate the negative association between depressive symptoms and work ability.

Methods

Two waves with a 3-year time lag of the German lidA cohort study with 3609 participants born in 1959 and 1965 (aged 46 and 52 years at first wave) were analyzed. Self-report data about depressive symptoms at baseline and changes of working conditions from baseline to follow-up were used to calculate main and interaction effects on perceived work ability at follow-up. These analyses were controlled for baseline work ability and working conditions.

Results

Depressive symptoms were predictive for an unfavorable course of work ability from baseline to follow-up (B = − 0.173, 95% CI = − 0.219 to − 0.128). However, no interaction effect between depressive symptoms and psychosocial working conditions was found. Instead, independent from the level of depressive symptoms, a decrease in quantitative demands (B = − 0.279, 95% CI = − 0.326 to − 0.232) and increases in leadership quality (B = 0.242, 95% CI = 0.192–0.292) and development opportunities (B = 0.177, 95% CI = 0.127–0.277) were related to a more favorable course of work ability. Only small effects were found for social support (B = 0.057, 95% CI = 0.008–0.106) and job control (B = 0.043, 95% CI = − 0.005–0.091).

Conclusions

The results indicate that the lagged and negative effect of depressive symptoms on work ability was not moderated by changes in psychosocial working conditions. However, the promotion of favorable working conditions may contribute to a positive development of work ability among employees from the Baby Boom generation independently from the level of depressive symptoms.

Work Ability, Burnout Complaints, and Work Engagement Among Employees With Chronic Diseases: Job Resources as Targets for Intervention?

PURPOSE

The aim of this study was to investigate the occupational well-being among employees with chronic diseases, and the buffering effect of four job resources, possibly offering targets to enhance occupational well-being.

METHOD

This cross-sectional study (N = 1951) was carried out among employees in educational and (semi-)governmental organizations in the Netherlands. The dimensions of the survey were chronic diseases (i.e., physical, mental, or both physical and mental), occupational well-being (i.e., work ability, burnout complaints, and work engagement), and job resources (i.e., autonomy, social support by colleagues, supportive leadership style, and open and communicative culture). First, it was analyzed if chronic diseases were associated with occupational well-being. Second, it was analyzed if each of the four job resources would predict better occupational well-being. Third, possible moderation effects between the chronic disease groups and each job resource on occupational well-being were examined. Regression analyses were used, controlling for age.

RESULTS

Each chronic disease group was associated with a lower work ability. However, higher burnout complaints and a lower work engagement were only predicted by the group with mental chronic diseases and by the group with both physical and mental chronic disease(s). Furthermore, all four job resources predicted lower burnout complaints and higher work engagement, while higher work ability was only predicted by autonomy and a supportive leadership style. Some moderation effects were observed. Autonomy buffered the negative relationship between the chronic disease groups with mental conditions (with or without physical conditions) and work ability, and the positive relationship between the group with both physical and mental chronic disease(s) and burnout complaints. Furthermore, a supportive leadership style is of less benefit for occupational well-being among the employees with mental chronic diseases (with or without physical chronic diseases) compared to the group employees without chronic diseases. No buffering was demonstrated for social support of colleagues and an open and communicative organizational culture.

CONCLUSION

Autonomy offers opportunities to reinforce occupational well-being among employees with mental chronic diseases. A supportive leadership style needs more investigation to clarify why this job resource is less beneficial for employees with mental chronic diseases than for the employees without chronic diseases.

Work ability and percentage of hours worked related to limitations in patients with upper extremity musculoskeletal disorders: a cross-sectional cohort study

Background

The aim of this study was to assess the relationship between self-reported work ability and hours worked at the current time in Upper Extremity Musculoskeletal Disorders (UEMSD) patients. To further investigate this relationship, the association of work ability and working hours with several limitations in daily and working life were explored.

Methods

In this cross-sectional cohort study, a questionnaire was sent out to members of the UEMSD patient organisation, containing self-reported work ability, questions on working hours and limitations in work due to UEMSD. Limitations were measured with the Disabilities of Arm Shoulder and Hand questionnaire, ShortForm-36 subscales, and common hand grasps or grips. Work ability was measured with the work ability score, while worked hours were operationalised as the percentage of hours worked compared to fulltime. The correlation between worked hours and work ability was tested with the Pearson correlation coefficient. Variance in work ability and the hours worked were explained by limitations and assessed with two linear regression analyses.

Results

Based on data of 794 respondents a moderate correlation was found between work ability and worked hours r = 0.46; 95% CI [0.40, 0.53]. Models including limitations explained 52 and 21% of total variance in work ability and worked hours, respectively. Variance in both can be explained by the degree of difficulties performing daily activities at work, limitations in daily activities as a consequence of health issues and the ability to perform a precision grip. Additionally, work ability can be explained by limitations at work and other daily activities due to physical health issues, while the percentage of hours can additionally be explained by the ability to grasp a large object with one hand, the ability to use a keyboard, and the subject’s gender.

Conclusions

The number of worked hours does not fully match the work ability. Although they share three predictors, work ability and worked hours seem to be based on different aspects. Compared to work hours, work ability is more strongly related to limitations in daily activities and work. Taking self-reported work ability into account can improve the fit between work limitations and work hours.

Out of pocket expenditures of patients with a chronic condition consulting a primary care provider in Tajikistan: a cross-sectional household survey

BACKGROUND

Within its reform efforts, the Government of Tajikistan is embracing the essential role of primary health care (PHC) in decreasing out of pocket (OOP) expenditures and increasing equity in access to health services. In the light of the increasing burden of disease relating to chronic conditions, we investigated OOP expenditures of patients with chronic conditions within a PHC setting; and if and how those expenditures are impacted by several interventions currently being implemented within Tajikistan.

METHODS

A cross-sectional survey among 1600 adult patients who had visited a PHC facility was conducted. The data obtained through interviews were descriptively analysed, and logistic regressions and gamma generalized linear models were performed.

RESULTS

The total OOP expenditures related to a patient's last visit to the PHC facility were 17.2 USD for those with chronic conditions and 13.9 USD for those visiting due to an acute condition. Adjustment for potential confounders reduced the discrepancy from 3.3 USD to 0.5 USD. This convergence of costs was only observed in districts covered by the Basic Benefit Package (BBP), a governmental pilot project, aiming to standardise exemptions for payment and formal co-payments for health care services. Hence, we found the BBP to have a protective impact for patients with chronic conditions. However, considering the demographics of these patients (older in age, with greater dependency on pensions and social aid, and lower socio-economic status) in combination with the 40% higher utilisation rate of PHC and the high rate of onward referrals to specialists; it is clear that patients with chronic conditions continue to face substantial long-term costs and disadvantages.

CONCLUSIONS

After accounting for confounders, patients with chronic and acute conditions faced similar costs related to a single visit to a PHC facility in districts covered by the BBP. However, greater efforts are required to ensure that citizens are well informed about their rights to health care, the BBP and the services that should be provided at no cost at the point of delivery. Moreover, the needs of patients with chronic conditions warrant a more integrative approach that takes long-term expenditures and services beyond the level of PHC into account.

Chronic health conditions and work-related stress in older adults participating in the Dutch workforce

The proportion of workers with chronic health conditions (CHCs) will increase over the years as pension reform is increasing the age of retirement in many European countries. This will increase the percentage of older adults with CHCs performing highly demanding work. This study sought to examine the association between common CHCs [cardiovascular disease (CVD), diabetes, arthritis, respiratory and sleep disorders] and three domains of work stress in older Dutch workers. This study used data from the first wave of the NIDI Pension Panel Study for working adults aged 60–65 years (n = 6793). Logistic regression models examined the strength of association between CHCs and (1) general work stress, (2) emotional, and (3) physical demands. All five CHC were independently associated with one or more domains of stress. After including all CHCs in the model, CVD, sleep disorders, and arthritis were significantly associated with general stress. Respiratory disorders, sleep disorders, and arthritis were significantly associated with physical demands. Diabetes (1.25, 95% CI 1.01–1.53), sleep disorders (1.99, 95% CI 1.72–2.31), and arthritis (1.18, 95% CI 1.06–1.31) were significantly associated with emotional demands. Our findings demonstrate that work stress is associated with prevalent CHCs, and these conditions are differentially associated with several domains of work stress in adults approaching retirement. More research is needed to understand the causal relationship between CHCs and work stress. Such research may provide insights for effective workplace and public health interventions to ensure that older workers remain physically and mentally healthy, and productive through their working years.

Quality of Life and Work Ability among Healthcare Personnel with Chronic Viral Hepatitis. Evaluation of the Inpatient Rehabilitation Program of the Wartenberg Clinic

The aim of this study was to research the impact of inpatient rehabilitation on work ability and health-related quality of life factors for healthcare personnel (HP) with chronic hepatitis B and C virus (HBV and HCV) infection. A prospective evaluation study with three data collection times without an external control group was conducted. HP (n = 163) with an occupational acquired chronic hepatitis B/C infection who participated in an inpatient rehabilitation program were surveyed. Information was collected on work ability (WAI—Work Ability Index), quality of life (SF-36—Short Form-36 Health Survey), and anxiety and depression-related symptoms (HADS-D—Hospital Anxiety and Depression Scale). The majority of participants had HCV infection. Work ability was poor, improved significantly until the end of treatment, and remained at a moderate level six months later. The SF-36 showed no change in physical health over the study period, the results regarding mental health were in the average range with a significant improvement directly after intervention. The HADS-D results indicate noteworthy anxiety and depression symptoms during the study period. The inpatient rehabilitation program proved to be effective in the short term regarding mental health (SF-36) and WAI. To ensure long lasting positive results, services aimed at enhancing physical and mental health should be provided as early as possible and on a recurring basis.

Determinants of voluntary early retirement for older workers with and without chronic diseases: A Danish prospective study

Aims: This study explored differences in determinants (i.e. health-related, work-related and social factors) of voluntary early retirement between older workers with and without chronic diseases in Denmark. Methods: Workers aged 56–64 years who were members of a voluntary early retirement scheme were selected from the Danish National Working Environment Survey (2008–2009) and were followed in a public register for four years. Cox regression analyses were performed separately for older workers with and without chronic disease to identify the associations between determinants and voluntary early retirement. To explore the differences between groups, an interaction term between the determinant and having a chronic disease was included in the analyses for the total population. Results: Among 1861 eligible older workers, determinants associated with a higher risk of voluntary early retirement included poorer self-rated health, more depressive symptoms, a higher physical workload, lower job satisfaction and lower influence at work. For older workers with a chronic disease (n=1185), the presence of work–family conflict was also associated with a higher risk of voluntary early retirement, whereas for those with no chronic disease (n=676), a poorer relationship with colleagues was an additional determinant. Higher emotional demands, a higher work pace and higher quantitative demands were not significantly associated with voluntary early retirement for either group. None of the interaction terms was found to be statistically significant (p>0.05). Conclusions: Determinants associated with voluntary early retirement did not significantly differ between older workers with or without a chronic disease in Denmark. We conclude that several health-related, work-related and social factors are important for prolonged labour force participation of older workers (with and without a chronic disease).

Effect of Stress on the Work Ability of Aging American Workers: Mediating Effects of Health

We examined how stress affects the work ability of an aging workforce, how health mediates this relationship, and how the effects of stress on work ability differ in relation to social status. We analyzed data from the Health and Retirement Survey, namely, 2921 observations in 2010, 2289 observations in 2012, and 2276 observations in 2014. Ongoing chronic stress, social status, health status, and associations with individual work ability were assessed with ordinary least squares regression. Stress was significantly inversely associated with work ability. Health may function as a mediator between individual stress and work ability. The effects of stress and health on work ability decreased as social status increased. To cope with the challenges of aging workforces, future policy-makers should consider job resources and social status.

Lifestyle and work ability in a general working population in Norway: a cross-sectional study

OBJECTIVES

The aim of this study was to investigate the association between multiple lifestyle-related risk factors (unhealthy diet, low leisure-time physical activity, overweight/obesity and smoking) and self-rated work ability in a general working population.

SETTING

Population-based cross-sectional study, in Telemark County, Norway, 2013.

PARTICIPANTS

A random sample of 50 000 subjects was invited to answer a self-administered questionnaire and 16 099 responded. Complete data on lifestyle and work ability were obtained for 10 355 participants aged 18-50 years all engaged in paid work during the preceding 12 months.

OUTCOME MEASURE

Work ability was assessed using the Work Ability Score (WAS)-the first question in the Work Ability Index. To study the association between multiple lifestyle risk factors and work ability, a lifestyle risk index was constructed and relationships examined using multiple logistic regression analysis.

RESULTS

Low work ability was more likely among subjects with an unhealthy diet (ORadj 1.3, 95% CI 1.02 to 1.5), inactive persons (ORadj 1.4, 95% CI 1.2 to 1.6), obese respondents (ORadj 1.5, 95% CI 1.3 to 1.7) and former and current smokers (ORadj 1.2, 95% CI 1.1 to 1.4 and 1.3, 95% CI 1.2 to 1.5, respectively). An additive relationship was observed between the lifestyle risk index and the likelihood of decreased work ability (moderate-risk score: ORadj 1.3; 95% CI 1.1 to 1.6; high-risk score: ORadj 1.9; 95% CI 1.6 to 2.2; very high risk score: ORadj 2.4; 95% CI 1.9 to 3.0). The overall population attributable fraction (PAF) of low work ability based on the overall risk index was 38%, while the PAFs of physical activity, smoking, body mass index and diet were 16%, 11%, 11% and 6%, respectively.

CONCLUSIONS

Lifestyle risk factors were associated with low work ability. An additive relationship was observed. The findings are considered relevant to occupational intervention programmes aimed at prevention and improvement of decreased work ability.

Prognostic effects of selection, optimization and compensation strategies on work ability: results from the representative lidA cohort study on work, age, and health in Germany

PURPOSE

Regarding the increased need for the retention of older employees in the workforce, this study investigates whether there are main and interactive longitudinal effects of selection, optimization, compensation and working conditions according to the job demand-control model on work ability in older employees.

METHODS

Longitudinal data of computer-assisted personal interviews with one follow-up after 3 years of 3961 participants (born in 1959 and 1965) of the representative German lidA cohort study was used. Multiple linear regressions were performed, analyzing prospective main and interactive effects of selection, optimization, compensation and working conditions during baseline on perceived work ability at follow-up.

RESULTS

Regarding selection, optimization and compensation, only compensation had a positive, but weak effect on work ability. Working conditions were more strongly related to work ability: decision authority and skill discretion had independent positive and job demands had independent negative effects on work ability. One interaction effect was observed between loss-based selection and decision authority, such that they mutually enhanced their positive effects on work ability. Only few and weak interactions among the sub-strategies, selection, optimization and compensation, were observed.

CONCLUSIONS

Results indicate that especially favorable working conditions in terms of high job control and low job demands, but also compensation might help older employees to maintain work ability.

Changes in autonomy, job demands and working hours after diagnosis of chronic disease: a comparison of employed and self-employed older persons using the English Longitudinal Study of Ageing (ELSA)

Background

Modifications in working conditions can accommodate changing needs of chronically ill persons. The self-employed may have more possibilities than employees to modify their working conditions. We investigate how working conditions change following diagnosis of chronic disease for employed and self-employed older persons.

Methods

We used waves 2–7 from the English Longitudinal Study of Ageing (ELSA). We included 1389 participants aged 50–60 years who reported no chronic disease at baseline. Using fixed-effects linear regression analysis, we investigated how autonomy, physical and psychosocial job demands and working hours changed following diagnosis of chronic disease.

Results

For employees, on diagnosis of chronic disease autonomy marginally decreased (−0.10, 95% CI −0.20 to 0.00) and physical job demands significantly increased (0.13, 95% CI 0.01 to 0.25), whereas for the self-employed autonomy did not significantly change and physical job demands decreased on diagnosis of chronic disease (−0.36, 95% CI −0.64 to –0.07), compared with prediagnosis levels. Psychosocial job demands did not change on diagnosis of chronic disease for employees or the self-employed. Working hours did not change for employees, but dropped for self-employed (although non-significantly) by about 2.8 hours on diagnosis of chronic disease (−2.78, 95% CI −6.03 to 0.48).

Conclusion

Improvements in working conditions after diagnosis of chronic disease were restricted to the self-employed. This could suggest that workplace adjustments are necessary after diagnosis of chronic disease, but that the self-employed are more likely to realise these. Policy seeking to extend working life should consider work(place) adjustments for chronically ill workers as a means to prevent early exit from work.

Work characteristics, motivational orientations, psychological work ability and job mobility intentions of older workers

Drawing on job design theories and a conceptual framework of work-related goals and motivation in later adulthood, the aim of this paper is to explore how work-related and individual factors are separately and jointly related to psychological work ability and bridge employment intentions via late job mobility. The cross-sectional study is based on a sample of 171 older Spanish workers aged 45–65 and beyond. We differentiated between groups of older workers in mid career (45–55 years of age) and in their later careers (56 years and beyond). Our results confirm that task characteristics and, secondarily, knowledge characteristics are the most relevant factors in perceptions of psychological work ability among aged workers. Both age groups display a very marked personal mastery trait, which mediates the relationships between job characteristics and both psychological work ability and late job mobility intentions. The paper concludes with a discussion of theoretical and practical implications and suggestions for future research on the issues implied in the psychological adjustment of older workers in their mid and late careers.

Employment among Patients Starting Dialysis in the United States

BACKGROUND AND OBJECTIVES

Patients with ESRD face significant challenges to remaining employed. It is unknown when in the course of kidney disease patients stop working.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We examined employment trends over time among patients ages 18-54 years old who initiated dialysis in the United States between 1996 and 2013 from a national ESRD registry. We compared unadjusted trends in employment at the start of dialysis and 6 months before ESRD and used linear probability models to estimate changes in employment over time after adjusting for patient characteristics and local unemployment rates in the general population. We also examined employment among selected vulnerable patient populations and changes in employment in the 6 months preceding dialysis initiation.

RESULTS

Employment was low among patients starting dialysis throughout the study period at 23%-24%, and 38% of patients who were employed 6 months before ESRD stopped working by dialysis initiation. However, after adjusting for observed characteristics, the probability of employment increased over time; patients starting dialysis between 2008 and 2013 had a 4.7% (95% confidence interval, 4.3% to 5.1%) increase in the absolute probability of employment at the start of dialysis compared with patients starting dialysis between 1996 and 2001. Black and Hispanic patients were less likely to be employed than other patients starting dialysis, but this gap narrowed during the study period.

CONCLUSIONS

Although working-aged patients in the United States starting dialysis have experienced increases in the adjusted probability of employment over time, employment at the start of dialysis has remained low.

Can favourable psychosocial working conditions in midlife moderate the risk of work exit for chronically ill workers? A 20-year follow-up of the Whitehall II study

Objectives

To investigate if favourable psychosocial working conditions can reduce the risk of work exit and specifically for workers with chronic disease.

Methods

Men and women (32%) aged 35–55, working and having no chronic disease at baseline of the Whitehall II study of London-based civil servants were selected (n=9040). We observed participants’ exit from work through retirement, health-related exit and unemployment, new diagnosis of chronic disease (ie, coronary heart disease, diabetes, stroke and cancer) and their psychosocial working conditions in midlife. Using cause-specific Cox models, we examined the association of chronic disease and favourable psychosocial working conditions and their interaction, with the three types of work exit. We adjusted for gender, occupational grade, educational level, remaining in civil service, spouse’s employment status and mental health.

Results

Chronic disease significantly increased the risk of any type of work exit (HR 1.27) and specifically the risk of health-related exit (HR 2.42). High skill discretion in midlife reduced the risk of any type of work exit (HR 0.90), retirement (HR 0.91) and health-related exit (HR 0.68). High work social support in midlife decreased the risk of health-related exit (HR 0.79) and unemployment (HR 0.71). Favourable psychosocial working conditions in midlife did not attenuate the association between chronic disease and work exit significantly.

Conclusions

The chronically ill have increased risks of work exit, especially through health-related exit routes. Chronic disease is an obstacle to extended working lives. Favourable working conditions directly relate to reduced risks of work exit.

Workability and Muscle Strength in Patients With Seropositive Rheumatoid Arthritis: Survey Study Protocol

Background

Rheumatoid arthritis (RA) and other rheumatic conditions not only fundamentally affect patients’ quality of life and physiological needs but are also negatively associated with work ability. The costs of poor work ability, which, in sum, are more than treatment costs, pose an economic burden to society and patients. Work ability in RA appears to be multifactorial; symptoms such as pain, swelling, and stiffness play a major role, as these directly affect functional disability. Also, RA patients typically suffer from reduced muscle strength. Lower extremity function and grip strengths especially impair their quality of life. However, the role of muscle strength and disease activity as determinants of work ability have not yet been studied.

Objective

The primary objective of this study is to compare work ability in working-age participants with seropositive RA and with high and low disease activity; the secondary objective is to evaluate the association of muscle strength, functional ability, and frailty with work ability.

Methods

This monocentric cross-sectional study will be conducted at a rheumatologic outpatient clinic and day hospital with approximately 100 seropositive RA patients aged <65 years. A clinical disease activity index as a measure for rheumatoid disease activity will be assessed during the patients’ routine visits at the clinic. Work ability, frailty, and functional disability will be evaluated with (self-reported) questionnaires as well as with physical tests (Work Ability Index/Score; Health Assessment Questionnaire Disability Index; Survey of Health, Ageing, and Retirement in Europe Frailty Instrument; Short Physical Performance Battery). Muscle strength will be determined with dynamometer measurements of isometric hand grip strength and quadriceps femoris muscle contraction strength. Sleep quality (Medical Outcomes Study Sleep Scale) and sexual functioning as physiological needs will additionally be determined with self-reported questionnaires.

Results

For this study funding has already been awarded and enrollment has been completed. Data are currently being evaluated.

Conclusions

This study will evaluate the association of work ability with modifiable parameters such as muscle strength and functional ability. It will provide further insights into work ability in RA and its associated risk factors. Any evidence of association will motivate further research, and the findings might encourage interventions focused specifically on improving muscle strength and lower extremity function to positively affect work ability.

Quality of Working Life of cancer survivors: associations with health- and work-related variables

PURPOSE

This study aimed to (1) describe the Quality of Working Life (QWL) of cancer survivors and (2) explore associations between the QWL of cancer survivors and health- and work-related variables.

METHODS

Employed and self-employed cancer survivors were recruited through hospitals and patient organizations. They completed the Quality of Working Life Questionnaire for Cancer Survivors (QWLQ-CS) and health- and work-related variables in this cross-sectional study. The QWL scores of cancer survivors were described, and associations between QWL and health- and work-related variables were assessed.

RESULTS

The QWLQ-CS was completed by 302 cancer survivors (28% male) with a mean age of 52 ± 8 years. They were diagnosed between 0 and 10 years ago with various types of cancer, such as breast cancers, gastrointestinal cancers, urological cancers, and haematological cancers. The QWL mean score of cancer survivors was 75 ± 12 (0-100). Cancer survivors had statistically significant lower QWL scores when they had been treated with chemotherapy or when they reported co-morbidity (p ≤ 0.05). Cancer survivors without managerial positions, with low incomes or physically demanding work, and who worked a proportion of their contract hours had statistically significantly lower QWL scores (p ≤ 0.05).

CONCLUSIONS

This study described the QWL of cancer survivors and associations between QWL and health- and work-related variables. Based on these variables, it is possible to indicate groups of cancer survivors who need more attention and support regarding QWL and work continuation.

Appraisal of work ability in relation to job-specific health requirements in ambulance workers

Purpose

To gain insight into which job-specific health requirements relate to work ability, the following two research questions were formulated: Which job-specific health requirements are associated with the appraisal of work ability in ambulance drivers and paramedics? How are appraisals of physical and mental work ability associated with the appraisal of overall work ability in ambulance drivers and paramedics?

Method

Workers Health Surveillance cross-sectional data of 506 ambulance workers (236 drivers and 270 paramedics) were used. The tests for specific job requirements were divided into six categories. Work ability was appraised as overall, physical and mental/emotional. Multiple linear stepwise regression analyses were used to model the associations.

Results

Outcomes in ‘raised alertness and judgment ability’ (R² = 0.09), ‘job-specific physical abilities’ (R² = 0.10) and ‘emotional peak load’ (R² = 0.07) significantly explained appraised overall, physical and mental/emotional work ability. Physical and mental/emotional work ability together explained 48.3% of the variance of overall work ability. The explained variance by physical and mental/emotional work ability was almost 4% higher in drivers than in paramedics.

Conclusions

Overall work ability was significantly explained by outcomes in ‘raised alertness and judgment ability’ and ‘emotional peak load.’ Physical work ability was significantly explained by ‘job-specific physical abilities’ and ‘raised alertness and judgment ability’ outcomes, while ‘emotional peak load’ and ‘raised alertness and judgment ability’ outcomes significantly explained mental/emotional work ability. Physical and mental/emotional work ability explains the same proportion of variance in overall work ability.

Prevalence and determinants of insufficient work ability in older HIV-positive and HIV-negative workers

PURPOSE

To explore whether the prevalence and determinants of insufficient work ability (WA) of older HIV-positive workers differ from a comparable group of HIV-negative workers.

METHODS

Cross-sectional data from 359 HIV-negative and 264 HIV-positive middle-aged individuals (45-65 years) participating in paid labor, collected within the AGEhIV Cohort Study between October 2010-September 2012, were selected. Data were collected by self-administered questionnaires and physical examination. Participants self-rated their current WA, ranging from 0 to 10. WA was dichotomized into insufficient (<6) and sufficient (≥6). Using univariable and multivariable logistic regression, we studied the independent effect of HIV status on insufficient WA and determinants of insufficient WA.

RESULTS

Overall, 8% of participants reported insufficient WA (HIV-positive 9 vs. HIV-negative 7%, P = 0.20). Twice as many HIV-positive as HIV-negative individuals were declared partly unfit for work (6 vs. 3%, P = 0.02). HIV status itself was not associated with WA in univariable and multivariable analyses. Multivariable analyses revealed that low educational level, working fewer hours, being partly unfit for work, experiencing a high need for recovery after work, staying home from work ≥2 times in the past 6 months, and reporting depressive symptoms were associated with insufficient WA, independent of HIV status.

CONCLUSIONS

HIV-positive individuals aged 45-65 years participating in paid labor seem to function as well at work as HIV-negative individuals. HIV-positive participants were more often formally declared partly unfit for work, but percentages were low in both groups. Knowledge of determinants of insufficient WA may help employers and professionals to optimize WA.

Measuring multimorbidity in a working population: the effect on incident sickness absence

PURPOSE

Multimorbidity research typically focuses on chronic and common diseases in patient and/or older populations. We propose a multidimensional multimorbidity score (MDMS) which incorporates chronic conditions, symptoms, and health behaviors for use in younger, presumably healthier, working populations.

METHODS

Cross-sectional study of 372,370 Spanish workers who underwent a standardized medical evaluation in 2006. We computed a MDMS (range 0-100) based on the sex-specific results of a multicorrespondence analysis (MCA). We then used Cox regression models to assess the predictive validity of this MDMS on incident sickness absence (SA) episodes.

RESULTS

Two dimensions in the MCA explained about 80% of the variability in both sexes: (1) chronic cardiovascular conditions and health behaviors, and (2) pain symptoms, in addition to sleep disturbances in women. More men than women had at least one condition (40 vs 15%) and two or more (i.e., multimorbidity) (12 vs 2%). The MDMS among those with multimorbidity ranged from 16.8 (SD 2.4) to 51.7 (SD 9.9) in men and 18.5 (SD 5.8) to 43.8 (SD 7.8) in women. We found that the greater the number of health conditions, the higher the risk of SA. A higher MDMS was also a risk factor for incident SA, even after adjusting for prior SA and other covariates. In women, this trend was less evident.

CONCLUSIONS

A score incorporating chronic health conditions, behaviors, and symptoms provides a more holistic approach to multimorbidity and may be useful for defining health status in working populations and for predicting key occupational outcomes.

Disease-generic factors of work participation of workers with a chronic disease: a systematic review

PURPOSE

The purpose of this review was to search systematically for disease-generic factors associated with either work retention (WR) or return to work (RTW) in people of working age with a chronic disease.

METHODS

An extensive search was performed in PubMed, EMBASE, PsycINFO and CINAHL for English-, Dutch- and German-language studies searching on synonyms of the terms chronic disease, WR and RTW. Studies were selected if they described factors related to WR or RTW and included participants with a chronic disease of working age (15-67 years old).

RESULTS

From 2597 hits in the electronic databases, we identified six studies reporting 23 factors associated with work participation. Categorized according to the International Classification of Functioning, Disability and Health, health-related factors (comorbidity, duration of symptoms and less dysfunction), environmental factors (work environment and duration of absence) and personal factors (age, gender, education and own prediction of RTW) were identified.

CONCLUSIONS

Various disease-generic factors are associated with work participation, of which most of the reported factors are independent of diagnosis. Evidence of the retrieved factors is restricted due to the limited availability of studies focusing on disease-generic factors and overall low quality of the retrieved studies.

A comparison of the relationships between psychosocial factors, occupational strain, and work ability among 4 ethnic teacher groups in China

The present study compared the level of occupational strain and work ability among Han, Hui, Uygur, Hui, and Kazakh teachers, and explored ethnic differences based on the associations of psychosocial factors at work, occupational strain, and work ability. A cross-sectional survey was conducted among 2,941 teachers in primary and secondary schools in Xinjiang Province, China. Psychosocial factors, occupational strain, and work ability were measured using the Occupation Stress Inventory-Revised Edition (OSI-R) and Work Ability Index. Han and Hui teachers experienced reduced work ability compared with Uygur and Kazakh teachers, and this finding was caused, in part, by exposure to psychosocial factors at work. The vocational and psychological strains caused by these factors play an important role in reduced work ability among all ethnic teacher groups. The findings indicate the importance of taking action to reduce occupational strain for promoting teachers' work ability in multiethnic workplaces.
