The association between self-efficacy and sick-leave among men and women: a cross-sectional study of the general working population in Sweden

Background: The aim of this study was to investigate if low self-efficacy was associated with increased risk for sickness absence, in a general population of employed women and men. The aim was also to analyse differences in self-efficacy concerning age, education, income, and socio-economic position. Methods: This cross-sectional study was based on data collected in western Sweden, 2008. The study population consisted of 2,900 employed sick-listed individuals (E-SL) and 2,649 random working population individuals (R-WP). Both mailed questionnaire, including the General Self-Efficacy Scale (GSE) and register data on age, education, income and socio-economic position were used. A continuous mean score of the total GSE was calculated for each individual. A low GSE-score indicated low general self-efficacy. Results: Lower general self-efficacy had an increased odds ratio (OR) of belonging to a sick-listed general working population among both men (OR=1.60; 95% CI 1.32–1.94) and women (OR=1.26; 95% CI 1.08–1.47). The OR remained significant after adjustments for socio-demographic variables. Yet, men in the R-WP and women in both the R-WP and E-SL with lower education, income or socio-economic position had lower general self-efficacy compared with those in each cohort with higher education, income or socio-economic position. Conclusions: Low self-efficacy was associated with increased probability to belong to a sick-listed general working population. Although more research is needed, it seems highly relevant to take both self-efficacy and socio-economic factors into account, in preventive and rehabilitation work targeting persons on sickness absence

Greenhouse Impact Due to the Use of Combustible Fuels: Life Cycle Viewpoint and Relative Radiative Forcing Commitment

Extensive information on the greenhouse impacts of various human actions is important in developing effective climate change mitigation strategies. The greenhouse impacts of combustible fuels consist not only of combustion emissions but also of emissions from the fuel production chain and possible effects on the ecosystem carbon storages. It is important to be able to assess the combined, total effect of these different emissions and to express the results in a comprehensive way. In this study, a new concept called relative radiative forcing commitment (RRFC) is presented and applied to depict the greenhouse impact of some combustible fuels currently used in Finland. RRFC is a ratio that accounts for the energy absorbed in the Earth system due to changes in greenhouse gas concentrations (production and combustion of fuel) compared to the energy released in the combustion of fuel. RRFC can also be expressed as a function of time in order to give a dynamic cumulative picture on the caused effect. Varying time horizons can be studied separately, as is the case when studying the effects of different climate policies on varying time scales. The RRFC for coal for 100 years is about 170, which means that in 100 years 170 times more energy is absorbed in the atmosphere due to the emissions of coal combustion activity than is released in combustion itself. RRFC values of the other studied fuel production chains varied from about 30 (forest residues fuel) to 190 (peat fuel) for the 100-year study period. The length of the studied time horizon had an impact on the RRFC values and, to some extent, on the relative positions of various fuels

Evaluating the greenhouse gas impact from biomass gasification systems in industrial clusters – methodology and examples

Biomass gasification is identified as one of the key technologies for producing biofuels for the transport sector and can also produce many other types of products. Biomass gasification systems are large-scale industrial systems and it is important to evaluate such systems from economic, environmental and synergetic perspectives before implementation. The objective of this study is to define a methodology for evaluating the greenhouse gas (GHG) impact of different biomass gasification systems and to exemplify the methodology. The ultimate purpose of the methodology is to evaluate the GHG performance of different biomass gasification systems integrated in industrial clusters. A life cycle perspective is applied. Most biomass gasification systems are multiproduct systems, simultaneously producing biofuels, heat at different temperatures and pressures and electricity. The value, in economic terms and in terms of GHG emissions, is well defined for some products (e.g. biofuels), whereas for other products (such as heat and electricity) it is more uncertain and in some cases dependent on time and location

Harmful alcohol habits did not explain the social gradient of sickness absence in Swedish women and men

Background: the aim of this study was to examine the prevalence and socioeconomic distribution of harmful alcohol habits in sick-listed women and men, and whether the social gradient in sickness absence could be explained by the socioeconomic distribution of harmful alcohol habits. Methods: this cross-sectional questionnaire study included newly sick-listed individuals (n=2 798, 19-64 years, 66% women) from Sweden. The outcome variable, self-reported harmful alcohol habits, was measured with the Alcohol Use Disorder Identification Test. Registered socioeconomic variables (education, income, occupational class) were explanatory variables with age as confounder and selfreported health, symptoms, mental wellbeing, and self-efficacy as mediators. Chi2-tests and logistic regression models were applied. Results: 9% of sick-listed women and 22% of men had harmful alcohol habits. Women with a low annual income (≤149 000 SEK) had higher odds ratios (OR=2.47; 95% CI=1.43-4.27) of harmful alcohol habits than those with ≥300 000 SEK/year. The significance of low income remained when mediators were introduced into the logistic regression model (OR=2.03, 95% CI=1.13-3.65). In the model including age, income was no longer significant. Men with low income were more likely to have harmful alcohol habits than men with high income (OR=2.59; 95% CI=1.45-4.62). When mediators were included low income remained significant (OR=2.88; 95% CI=1.56-5.31). Income was no longer significant when age was introduced. Education and occupational status were not significant. Conclusions: harmful alcohol habits were common among sick-listed women and men. The socioeconomic differences in harmful alcohol habits did not explain the social gradient in sickness absence

Exploring reasons for sick leave due to common mental disorders from the perspective of employees and managers:what has gender got to do with it?

PURPOSE: The purpose of this study was to explore the employee and the managerial experience of reasons for sick leave due to CMDs in relation to work and private life, through the lens of a transactional perspective of everyday life occupation and gender norms. METHODS: Semi-structured interviews were conducted with 17 employees on sick leave due to CMDs and 11 managers. By using transactional and gender perspectives in a reflexive thematic analysis, themes were generated in a constant comparative process. FINDINGS: Four themes were identified: a) struggling to keep up with work pressure and worker norms; b) struggling with insecurity in an unsupportive work environment; c) managing private responsibilities through flexible work schedules, and d) managing emotions alongside unfavourable working conditions. CONCLUSION: Sick leave due to CMDs was understood as related to experiences of accumulated events situated in different social, cultural, and societal contexts of everyday life. Practices and policies should encourage an open dialogue about work and private life and health between employees and managers. To build healthy and sustainable work environments practices should also aim for increased awareness of social norms. A better understanding may facilitate the identification of situations in work and private life that are problematic for the employee

Experiences of participating in a problem-solving intervention with workplace involvement in Swedish primary health care:a qualitative study from rehabilitation coordinator's, employee's, and manager's perspectives

BACKGROUND: Work-directed interventions that include problem-solving can reduce the number of sickness absence days. The effect of combining a problem-solving intervention with involvement of the employer is currently being tested in primary care in Sweden for employees on sickness absence due to common mental disorders (PROSA trial). The current study is part of the PROSA trial and has a two-fold aim: 1) to explore the experiences of participating in a problem-solving intervention with workplace involvement aimed at reducing sickness absence in employees with common mental disorders, delivered in Swedish primary health care, and 2) to identify facilitators of and barriers to participate in the intervention. Both aims targeted rehabilitation coordinators, employees on sickness absence, and first-line managers.METHODS: Data were collected from semi-structured interviews with participants from the PROSA intervention group; rehabilitation coordinators (n = 8), employees (n = 13), and first-line managers (n = 8). Content analysis was used to analyse the data and the Consolidated Framework for Implementation Research was used to group the data according to four contextual domains. One theme describing the participation experiences was established for each domain. Facilitators and barriers for each domain and stakeholder group were identified.RESULTS: The stakeholders experienced the intervention as supportive in identifying problems and solutions and enabling a dialogue between them. However, the intervention was considered demanding and good relationships between the stakeholders were needed. Facilitating factors were the manual and work sheets which the coordinators were provided with, and the manager being involved early in the return-to-work process. Barriers were the number of on-site meetings, disagreements and conflicts between employees and first-line managers, and symptom severity.CONCLUSIONS: Seeing the workplace as an integral part of the intervention by always conducting a three-part meeting enabled a dialogue that can be used to identify and address disagreements, to explain CMD symptoms, and how these can be handled at the workplace. We suggest allocating time towards developing good relationships, provide RCs with training in handling disagreements, and additional knowledge about factors in the employee's psychosocial work environment that can impair or promote health to increase the RCs ability to support the employee and manager.</p

Increasing return-to-work among people on sick leave due to common mental disorders:Design of a cluster-randomized controlled trial of a problem-solving intervention versus care-as-usual conducted in the Swedish primary health care system (PROSA)

Background: Common mental disorders affect about one-third of the European working-age population and are one of the leading causes of sick leave in Sweden and other OECD countries. Besides the individual suffering, the costs for society are high. This paper describes the design of a study to evaluate a work-related, problem-solving intervention provided at primary health care centers for employees on sick leave due to common mental disorders.Methods: The study has a two-armed cluster randomized design in which the participating rehabilitation coordinators are randomized into delivering the intervention or providing care-as-usual. Employees on sick leave due to common mental disorders will be recruited by an independent research assistant. The intervention aims to improve the employee's return-to-work process by identifying problems perceived as hindering return-to-work and finding solutions. The rehabilitation coordinator facilitates a participatory approach, in which the employee and the employer together identify obstacles and solutions in relation to the work situation. The primary outcome is total number of sick leave days during the 18-month follow-up after inclusion. A long-term follow-up at 36 months is planned. Secondary outcomes are short-term sick leave (min. 2 weeks and max. 12 weeks), psychological symptoms, work ability, presenteeism and health related quality of life assessed at baseline, 6 and 12-month follow-up. Intervention fidelity, reach, dose delivered and dose received will be examined in a process evaluation. An economic evaluation will put health-related quality of life and sick leave in relation to costs from the perspectives of society and health care services. A parallel ethical evaluation will focus on the interventions consequences for patient autonomy, privacy, equality, fairness and professional ethos and integrity.Discussion: The study is a pragmatic trial which will include analyses of the intervention's effectiveness, and a process evaluation in primary health care settings. Methodological strengths and challenges are discussed, such as the risk of selection bias, contamination and detection bias. If the intervention shows promising results for return-to-work, the prospects are good for implementing the intervention in routine primary health care.</p

The usefulness of rapid diagnostic tests in the new context of low malaria transmission in zanzibar.

BACKGROUND\ud \ud We assessed if histidine-rich-protein-2 (HRP2) based rapid diagnostic test (RDT) remains an efficient tool for Plasmodium falciparum case detection among fever patients in Zanzibar and if primary health care workers continue to adhere to RDT results in the new epidemiological context of low malaria transmission. Further, we evaluated the performance of RDT within the newly adopted integrated management of childhood illness (IMCI) algorithm in Zanzibar.\ud \ud METHODS AND FINDINGS\ud \ud We enrolled 3890 patients aged ≥2 months with uncomplicated febrile illness in this health facility based observational study conducted in 12 primary health care facilities in Zanzibar, between May-July 2010. One patient had an inconclusive RDT result. Overall 121/3889 (3.1%) patients were RDT positive. The highest RDT positivity rate, 32/528 (6.1%), was found in children aged 5-14 years. RDT sensitivity and specificity against PCR was 76.5% (95% CI 69.0-83.9%) and 99.9% (95% CI 99.7-100%), and against blood smear microscopy 78.6% (95% CI 70.8-85.1%) and 99.7% (95% CI 99.6-99.9%), respectively. All RDT positive, but only 3/3768 RDT negative patients received anti-malarial treatment. Adherence to RDT results was thus 3887/3889 (99.9%). RDT performed well in the IMCI algorithm with equally high adherence among children <5 years as compared with other age groups.\ud \ud CONCLUSIONS\ud \ud The sensitivity of HRP-2 based RDT in the hands of health care workers compared with both PCR and microscopy for P. falciparum case detection was relatively low, whereas adherence to test results with anti-malarial treatment was excellent. Moreover, the results provide evidence that RDT can be reliably integrated in IMCI as a tool for improved childhood fever management. However, the relatively low RDT sensitivity highlights the need for improved quality control of RDT use in primary health care facilities, but also for more sensitive point-of-care malaria diagnostic tools in the new epidemiological context of low malaria transmission in Zanzibar.\ud \ud TRIAL REGISTRATION\ud \ud ClinicalTrials.gov NCT01002066

A possible role for miRNA silencing in disease phenotype variation in Swedish transthyretin V30M carriers

Our results are the first to show the presence of a 3'UTR polymorphism on the V30M haplotype in Swedish carriers, which can serve as a miRNA binding site potentially leading to down-regulated expression from the mutated TTR allele. This finding may be related to the low penetrance and high age at onset of the disease observed in the Swedish patient population
