To examine age-group and birth-cohort trends in perceived work ability in Finland in 2000-2020 and make projections of perceived work ability up to 2040 based on the observed birth-cohort development. Ten population-representative cross-sectional surveys conducted in Finland between 2000 and 2020 were used (overall = 61,087, range 817-18,956). Self-reported estimates of current work ability in relation to the person's lifetime best on a scale from zero to ten (0-10) were classified into three groups: limited (0-5), intermediate (6-7), and good (8-10).

Article Synopsis
  • The study investigated the relationship between unhealthy behaviors (like poor diet and excessive alcohol use) and sickness absence (SA) among Finnish municipal employees using a person-oriented approach.
  • A questionnaire was completed by 4,002 employees, revealing distinct patterns of unhealthy behaviors that correlated with increased SA rates.
  • It concluded that effective prevention strategies for reducing SA should address multiple unhealthy behaviors simultaneously, focusing on specific clusters relevant to different occupational groups.

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.

Occupational class differences in leisure-time physical activity (LTPA) are well recognized. Less is known about how these differences develop as individuals age, and how retirement is associated with this change. We investigated how occupational class differences in LTPA change in a cohort over a 15-17 years follow-up.

Studies examining occupational class differences in burnout symptoms across employment sectors are scarce. The aim of this study was to examine whether occupational class is associated with emotional exhaustion, and whether there are differences in the examined associations between employment sectors. A further aim was to examine to which extent psychosocial working conditions may explain these associations.

Aim: The study aimed to critically review and synthesize the best available evidence about the effectiveness of therapist-guided internet-delivered cognitive behavioral therapy (iCBT) in terms of reducing sickness absence (SA).

Methods: We searched Medline (PubMed), Embase, PsycInfo, CINAHL, and Cochrane Central (up to November 2020) for English language peer-reviewed papers that described randomized controlled trials of therapist-guided iCBT compared with usual treatment for SA in adults with common mental disorders. Eligible studies were assessed with the Cochrane Risk of Bias 1 tool, meta-analysis was conducted using a random-effects model, and standardized mean differences (SMD) with 95% confidence intervals (CI) were reported.

There is a lack of longitudinal, population-based studies on the association between education and smoking cessation. A more thorough examination of this association is needed to address inequalities in smoking. The longitudinal Health 2000 Survey and Health 2011 Survey, representing the Finnish population aged ⩾30 years, were analysed.

Sleep and functioning are associated with a risk of early workforce exit. However, patterns of change in sleep and functioning through time have not been investigated using person-oriented approaches to show what features of sleep and functioning are associated with an early exit. We examined the pattern of interactions between sleep and health functioning characterizing homogenous subgroups of employees and their associations with premature work exit.

The aim was to examine whether the contribution of physical work exposures to the risk of sickness absence (SA) is different between those with and without common mental disorders (CMD). We used questionnaire data on four work exposures and CMD from 6159 participants of the Helsinki Health Study cohort with 12,458 observations from three surveys (2000-2002, 2007 and 2012). We formed combination exposures for the work exposures (hazardous exposures, physical workload, computer and shift work) with CMD.

Introduction: Depression is a highly prevalent condition with typical onset in early adulthood. Internet-delivered cognitive behavioural therapy (iCBT) is a promising cost-effective and more widely available alternative to face-to-face CBT. However, it is not known whether it can reduce sickness absence in employees showing depressive symptoms.

Article Synopsis
  • Unhealthy lifestyles, particularly poor diet and inactivity, are linked to higher sickness absence costs for employers.
  • The study analyzed data from 4,157 employees in Helsinki, examining the impact of dietary changes and physical activity on short-term sickness absence costs from 2008-2012.
  • Improved daily fruit and vegetable consumption and continued physical activity led to significantly lower costs for employers, suggesting that enhancing employee health can reduce sickness absence costs, although dietary changes alone weren't directly tied to cost reductions.

Physical inactivity has been associated with both insomnia symptoms and smoking. Further, they are all independently associated with increased sickness absence (SA) from work. However, joint contribution of either physical activity (PA) with insomnia symptoms or with smoking to SA and, especially, their direct cost for the employer is poorly understood.
