This study aimed to investigate economic self-sufficiency for immigrants, and how health status affected self-sufficiency. The proportion of self-sufficiency during years 1–10 after receiving a residence permit is presented for all non-European labour immigrants (n = 1259) and refugees (n = 23,859), aged 18–54, who immigrated to Sweden 2000–2006, and compared to a control group of Swedish-born (n = 144,745). The risk of not being self-sufficient in year 10 was analysed with Cox regression models, and the results are presented as hazard ratios (HRs) with 95% confidence intervals (CIs). Moreover, the impact on the self-sufficiency of having a diagnosis from specialised health care during the first five years in Sweden was analysed. The results showed that half of the refugees and three-quarters of the labour immigrants were self-sufficient 10 years after residency. The adjusted risk of not being self-sufficient at year 10 was 80% higher among labour immigrants (HR = 1.8; CI = 1.6–2.0) and more than two-fold among refugees (HR = 2.7; CI = 2.6–2.8) compared to the Swedish-born. Having a diagnosis from specialised health care during the first five years in Sweden had an impact on self-sufficiency in all groups; however, the impact of having a diagnosis did not differ between refugees and Swedish-born. Measures must be taken to increase immigrants’ work participation.

Two mathematical models of human thermal regulation include the rational Predicted Heat Strain (PHS) and the thermophysiological model by Fiala. The approaches of the models are different, however, they both aim at providing predictions of the thermophysiological responses to thermal environments of an average person. The aim of this study was to compare and analyze predictions of the two models against experimental data. The analysis also includes a gender comparison. The experimental data comprised of ten participants (5 males, 5 females, average anthropometric values were used as input) conducting an intermittent protocol of rotating tasks (cycling, stacking, stepping and arm crank) of moderate metabolic activities (134-291W/m2) with breaks in-between in a controlled environmental condition (34°C, 60% RH). The validation consisted of the predictions' comparison against experimental data from 2.5h of data of rectal temperature and mean skin temperature based on contact thermometry from four body locations. The PHS model over-predicted rectal temperatures during the first activity for males and the cooling effectiveness of sweat in the recovery periods, for both males and females. As a result, the PHS simulation underestimated the thermal strain in this context. The Fiala model accurately predicted the rectal temperature throughout the exposure. The fluctuation of the experimental mean skin temperature was not reflected in any of the models. However, the PHS simulation model showed better agreement than the Fiala model. As both models predicted responses more accurately for males than females, we suggest that in future development of the models it is important to take this result into account. The paper further discusses possible sources of the observed discrepancies and concludes with some suggestions for modifications.

highlights abstract Objective: It is still not clarified whether spasticity contributes to impairments of gait function. Here we compared biomechanical measures of muscle weakness and stiffness of ankle muscles to impairments of gait function in adults with cerebral palsy (CP). Methods: Twenty-four adults with CP (mean age 34.3, range 18-57 years) and fifteen healthy age- matched controls were biomechanically measured for passive and reflex-mediated stiffness of the ankle plantarflexors at rest, maximal voluntary plantarflexion and dorsiflexion effort (MVCpf,df) and rate of force development (RFDpf,df). Kinematic analysis of the ankle joint during treadmill walking was obtained by 3- D motion analysis. Results: Passive stiffness was significantly increased in adults with CP compared to controls. Passive stiff- ness and RFDdf were correlated to reduced toe lift. RFDpf provided the best correlation to push-off velo- city, range of movement in the ankle joint and gait speed. Reflex-mediated stiffness was not correlated to any parameters of impaired gait. Conclusions: Impaired gait function in adults with CP is associated with reduced RFD and increased pas- sive stiffness of ankle muscles. Significance: These findings suggest that reduced rapid force generation and increased passive stiffness of ankle muscles rather than increased reflex-mediated stiffness (spasticity) likely contributes to impaired gait function in adults with CP.

Background A systematic attempt to summarize the literature that examines working conditions and occupational health among immigrant in Europe and Canada. Methods We established inclusion criteria, searched systematically for articles included in the Medline, Embase and Social Sciences Citation Index databases in the period 2000–2016 and checked the reference lists of all included papers. Results Eighty-two studies were included in this review; 90% were cross-sectional and 80% were based on self-report. Work injuries were consistently found to be more prevalent among immigrants in studies from different countries and in studies with different designs. The prevalence of perceived discrimination or bullying was found to be consistently higher among immigrant workers than among natives. In general, however, we found that the evidence that immigrant workers are more likely to be exposed to physical or chemical hazards and poor psychosocial working conditions is very limited. A few Scandinavian studies support the idea that occupational factors may partly contribute to the higher risk of sick leave or disability pension observed among immigrants. However, the evidence for working conditions as a potential mediator of the associations between immigrant status and poor general health and mental distress was very limited. Conclusion Some indicators suggest that immigrant workers in Europe and Canada experience poorer working conditions and occupational health than do native workers. However, the ability to draw conclusions is limited by the large gaps in the available data, heterogeneity of immigrant working populations, and the lack of prospectively designed cohort studies.

Background: Sickness absence with cash benefits from the sickness insurance gives an opportunity to be relieved from work without losing financial security. There are, however, downsides to taking sickness absence. Periods of sickness absence, even short ones, can increase the risk for future spells of sickness absence and unemployment. The sickness period may in itself have a detrimental effect on health. The aim of the study was to investigate if there is an association between exposure to sickness absence at a young age and later sickness absence, disability pension, death, unemployment and income from work. Methods: Our cohort consisted of all immigrants aged 21-25 years in Sweden in 1993 (N=38 207) and a control group of native Swedes in the same age group (N=225 977). We measured exposure to sickness absence in 1993 with a follow-up period of 15 years. We conducted separate analyses for men and women, and for immigrants and native Swedes. Results: Exposure to >= 60 days of sickness absence in 1993 increased the risk of sickness absence [hazard ratio (HR) 1.6-11.4], unemployment (HR 1.1-1.2), disability pension (HR 1.2-5.3) and death (HR 1.2-3.5). The income from work, during the follow-up period, among individuals with spells of sick leave for >= 60 days in 1993 was around two-thirds of that of the working population who did not take sick leave. Conclusions: Individuals on sickness absence had an increased risk for work absence, death and lower future income.

The present workforce in the mining industry is ageing, and mining companies have difficulties recruiting young people who are not particularly interested in working in the industry. Simultaneously, mining companies tend to rely on contractors that offer volume flexibility and expertise, often in a combination that is economically appealing. This makes recruitment and development of the whole of the mining workforce complex. To recruit the right workforce, mining companies and their contractors need to cooperate and improve their knowledge about both attractive and repelling work features so that they can make wiser strategic decisions based on facts. On the basis of a Swedish context, we discuss different aspects of attractive workplaces and summarise our 'lessons learned' in six recommendations dealing with general health and safety issues, work organisation, competence development, gender equality, social responsibility and outsourcing.

The aim of this register-based longitudinal study was to explore the relationship between exposure to unemployment and sick leave at a young age and later health and work related outcomes. A comparison was also made between immigrants and native Swedes. The study population consisted of all immigrants, born between 1968 and 1972, and a random sample of native Swedes in the same age range. The follow-up period was 15 years, divided into three 5-year periods. Unemployment in 1992 was associated with later ≥60 days of sickness absence, disability pension and, for all subjects except native Swedish women, also mortality during follow-up. The risk of future sickness absence was about the same in all three follow-up periods. There was an increased risk of ≥100 days of unemployment in all three follow-up periods, but the risk declined, however, until the last follow-up period. Higher level of education at baseline as well as education attained between 1993 and 1997 decreased the risk of future unemployment. Participating in active labour market programmes was associated with higher risk of future unemployment. The risk of both future unemployment and future sickness absence increased with the length of unemployment in 1992. Immigrants had a higher risk of unemployment both at baseline and at follow-up compared with native Swedes, but matched the pattern of native Swedes during follow-up. Exposure to ≥60 days of sickness absence in 1993 was associated with increased risk for ≥60 days of sickness absence, ≥100 days of unemployment, disability pension and mortality during follow-up compared with no sick leave at baseline. The income from work, during the follow-up period, among individuals with spells of sick leave ≥60 days in 1993 was around two-thirds of that of individuals not on >60 days of sick leave. There was a rapid increase in future work absence for the first 1–7 days of sick leave claimed. Thereafter there was a lower, but steady increase in days of future work absence for every increase in sick leave. This of course affects the individual in the first place and to a society it means substantial costs in the form of increased welfare payments, and loss of productivity and tax income.
