In this study perceived mental stress during occupational work was compared to heart rate variability (HRV) using a traditional questionnaire and a novel wristop heart rate monitor with related software. (r = -.73 and r = -.60, respectively). The analysis shows that as the RMSSD and TINN value differences increase from night to morning, the stress decreases. The aim was to find HRV parameters useful for mental stress detection. We found the highest correlation between perceived mental stress with the differences between the values of triangular interpolation of rythm-to-rythm (RR) interval histogram (TINN) and the root mean square of differences of successive RR intervals (RMSSD) obtained in the morning and during the workdaywork stress wristop computer heart rate variability o o 276

The main purpose of this study was to ascertain musculoskeletal and cardiovascular capacity among ageing employees in relation to workload over a period of 16 years. The data were obtained by physical capacity tests and ratings of perceived exertion (RPE) during working day. The study group consisted of 89 subjects, who were all employed in the municipal branch and were on average 51.9 years old at the beginning of the follow-up period in 1981 and 67.3 years in 1997, when the most of the subjects had retired (with only two subjects still working). During the 16-year follow-up period, age-related decline in physical capacity was observed. Nevertheless the improvement in flexibility of spine and in isometric trunk muscle strength compared with the same age subjects was more common among the subjects with high workload than among the subjects with low workload. However, among the subjects with high workload, physical capacity was poorer than among the subjects with low workload, especially among the women. The results suggest the conclusion that there are differences in workers' physical capacity in relation to their perceived workload during working life. These differences remained when the subjects had retired. Interestingly, those who had high workload had lower muscle strength than those who had low workload. This may indicate that high physical workload does not have any training effect on the muscle strength of ageing workers.

The purpose of the present study was to identify changes in different components of physical capacity among middle-aged women and men employed in the municipal branch for 16 years. The data were obtained by laboratory measurements and postal questionnaires. The study group consisted of 45 middle-aged subjects, who were on average 51.5 years old at the beginning of the follow-up in 1981 and 67.3 years in 1997. During the 16-year follow-up period, the average physical capacity of these workers decreased by approximately 20%. The study showed that the greatest changes occurred in isometric trunk muscle strength and in the flexibility of the spine, whereas smaller changes were noted in anthropometrics. The decrease of physical capacity was greater among men (range 11.6% to 33.7%) than among women (range 3.3% to 26.7%), although women had more individual variations. On average, people without disease or who were physically active displayed better physical capacity than people with disease or who were physically passive.

Sick leaves in four factories-do characteristics of employees and work conditions explain differences in sickness absence between workplaces? Scand J Work Environ Health 2008;34(4):260-266. ObjectivesThe study explored whether differences in sickness absence between four factories of a food industry company were explained by common determinants of sickness absence, such as employee health, sociodemographic characteristics, and physical and psychosocial work conditions. Methods Survey responses of 582 employees were linked to the records of short-term (1-3 days) and long-term (>3 days) absence, as well as to records of absences due to musculoskeletal diagnoses. Multilevel models were applied in assessing the between-factory absence differences.Results Compared with the levels in the factory with the lowest sickness absence, in one factory the levels of short-term [rate ratio (RR) 1.72], long-term (RR 1.96), and musculoskeletal (RR 2.93) absence were significantly higher. Another factory also had higher levels of long-term and musculoskeletal absence (RR 2.17 and 2.52, respectively). Adjustment for the background factors explained 35% of the difference in short-term absence, 3-9% of the differences in long-term absence, and 18-12% of the differences in musculoskeletal absence, but the between-factory differences were still highly significant. ConclusionsThis study showed large differences in sickness absence between factories that were only partly explained by common determinants. Moreover, economic factors and formal control were unlikely explanatory factors, as the study was conducted within a single company. These results justify further research on local absence practices and cultures, including those of health service organizations and professionals.

Background: The unemployed have lower work ability and poorer health than the employed. This situation deteriorates when unemployment continues. The long-term unemployed often have co-morbidities and face many other challenges. This increases the need for a multidimensional assessment of work ability and functioning in different service settings. In this study, we describe the development and analyse the content validity of the Abilitator, a self-report questionnaire on work ability and functioning for those in a weak labour market position. Methods: The Abilitator was developed in 2014-2017. Its construct was assessed by members of academic expert panels (n = 30), practical expert panels of professionals (n = 700) and target group clients (n = 28). The structure and the content of the questionnaire was co-developed in 29 workshops and adjusted twice based on the expert panels' feedback. The Abilitator was also implemented among target group clients (n = 3360) in different services and projects. During its development the Abilitator was linked to the International Classification of Functioning, Disability and Health (ICF). The content validation process followed the guidelines recommended by the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) panel. Results: The construct of the Abilitator combines the multidimensional and biopsychosocial models of work ability and functioning. It also includes aspects of social inclusion and employability. It evaluates social, psychological, cognitive and physical functioning, and the ability to cope with everyday life. The content of these concepts was validated by the academic and practical expert panels. The Abilitator's 79 ICF codes covered 57% of the Generic, 77% of the Brief Vocational Rehabilitation, and 8% of the Minimal Environmental ICF Core Sets. When compared with the Work Ability Index (WAI) and the World Health Organization Disability Assessment Schedule (WHODAS 2.0), the direct equivalences of the ICF codes were 36 and 44%, respectively. Conclusion: The Abilitator sufficiently comprehensively covers the relevant aspects to enable the assessment of the overall work ability and functioning of the population in a weak labour market position.
