Status inconsistency and return to work among foreign-born and native Swedes

We investigated potential differences in status inconsistency and time to return to work (RTW) from sickness absence between foreign-born and native Swedes, whether inconsistency was associated with RTW, and if this association was stronger for foreign-borns than natives. Significantly fewer native than foreign-born Swedes reported negative status inconsistency, but RTW did not differ between the groups and inconsistency was not associated with RTW. A positive selection of individuals to the Swedish labour market might help explain the findings. This first study of status inconcistency and RTW requires follow-ups in different settings of labour markets and insurance regulations

Alcohol environment, gender and nonfatal injuries in young people. An ecological study of fourteen Swedish municipalities (2000–2005)

BACKGROUND: Sweden has had a restrictive alcohol policy, but there are gender and geographical differences in alcohol consumption and injury rates within the country. Whether and how the Swedish alcohol environment influences gender differences in injuries in young people is still unclear. Thus, the aim of this study was to analyse the associations between the local alcohol environment and age- and gender-specific nonfatal injury rates in people up to 24 years in Sweden. METHODS: The local alcohol environment from 14 municipalities was studied using indicators of alcohol access, alcohol consumption and alcohol-related crimes. A comprehensive health care register of nonfatal injuries was used to estimate mean annual rates of nonfatal injuries by gender and age group (2000–2005). Pearson’s correlation coefficients were used to analyse linear associations. RESULTS: Associations were shown for both alcohol access and alcohol consumption with injury rates in boys aged 13–17 years; no other associations were observed between alcohol access or per capita alcohol consumption and nonfatal childhood injuries. The prevalence of crimes against alcohol laws was associated with injury rates in children of both genders aged 6–17 years. CONCLUSIONS: This study found no strong area-level associations between alcohol and age and gender specific nonfatal injuries in young people. Further, the strength of the area-level associations varied by age, gender and type of indicator used to study the local alcohol environment

Validity of the Capacity to Work Index:Development of an Instrument to Measure Work Capacity in Relation to Depression and Anxiety in the General Working Population

Purpose To develop an index to assess capacity to work in relation to common mental disorders (CMDs) in the generalworking population and field test its psychometric properties.Methods Content analysis of three qualitative studies on people (n = 49) with their own experiences of working with CMDguided the items selected for the index. Face and content validity and test-retest reliability were performed. The index wasfield tested in two versions with 26 and 17 items, respectively, among health care professionals regarding internal reliability,component structure and concurrent validity.Results The final version of the Capacity to Work Index (C2WI; 17 items) was normally distributed in the field test withhigh internal reliability (Cronbach’s alpha, 0.84). Missing responses were randomly distributed and nonspecific. Principalcomponent analysis showed one clear component with negatively framed items. Concurrent validity showed high correlationwith the WHO-5 Well-Being Scale (Pearson’s r, 0.68), but lower correlation for the general health question (r, − 0.44), oneitem of the Work Ability Index (r, − 0.33), and the Stress of Conscience constructs (r, 0.44).Conclusion The C2WI showed promising psychometric qualities. Low and negative correlation with the item from WorkAbility Index suggests that the C2WI measures additional dimensions, but further testing in larger and more diverse samplesis required

Um olhar para as atividades de educação ambiental em um periódico da área

The present Course Conclusion Paper (TCC) aims to present the analysis made in articles of the Revista Eletrônica do Mestrado em Educação Ambiental (REMEA), observing the descriptors: Environmental Education, Water and Food, in the titles delimited between years 2012 to 2017. Of the 215 articles selected, we made a new search using the descriptors: project, questionnaire, interview, didactic game, model and drawing. The current research through REMEA publications has brought knowledge to understand beyond an EA concerned with solid waste recycling, in which the use of projects as an EA activity contributes to the formation of subjects with responsibility for the preservation of water resources, for example, the fauna and flora important to our planet.O presente Trabalho de Conclusão de Curso (TCC) tem como propósito apresentar a análise feita em artigos da Revista Eletrônica do Mestrado em Educação Ambiental (REMEA), em observação aos descritores: Educação Ambiental, Água e Alimentação, nos títulos delimitados entre os anos 2012 a 2017. Dos 215 artigos selecionados fizemos nova busca usando os descritores: projeto, questionário, entrevista, jogo didático, maquete e desenho. A atual pesquisa por meio das publicações da REMEA trouxe conhecimento para entendermos para além de uma EA preocupada com a reciclagem dos resíduos sólidos, em que o uso de projetos como atividade de EA contribui na formação de sujeitos com responsabilidade para a preservação dos recursos hídricos, por exemplo, da fauna e flora importantes para o nosso Planeta

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

Factors associated with first return to work and sick leave durations in workers with common mental disorders

Background: Associations are examined between socio-demographic, medical, work-related and organizational factors and the moment of first return to work (RTW) (within or after 6 weeks of sick leave) and total sick leave duration in sick leave spells due to common mental disorders. Methods: Data are derived from a Dutch database, build to provide reference data for sick leave duration for various medical conditions. The cases in this study were entered in 2004 and 2005 by specially trained occupational health physicians, based on the physician's assessment of medical and other factors. Odds ratios for first RTW and sick leave durations are calculated in logistic regression models. Results: Burnout, depression and anxiety disorder are associated with longer sick leave duration. Similar, but weaker associations were found for female sex, being a teacher, small company size and moderate or high psychosocial hazard. Distress is associated with shorter sick leave duration. Medical factors, psychosocial hazard and company size are also and analogously associated with first RTW. Part-time work is associated with delayed first RTW. The strength of the associations varies for various factors and for different sick leave durations. Conclusion: The medical diagnosis has a strong relation with the moment of first RTW and the duration of sick leave spells in mental disorders, but the influence of demographic and work-related factors should not be neglected
