Sustentabilidade e bem-estar humano : duas faces da mesma moeda? : estudo exploratório do bem estar subjectivo em comunidades intencionais que vivem segundo princípios de sustentabilidade

RESUMO - Nos últimos vinte anos tem-se assistido a uma crescente consciencialização de que os nossos estilos de vida são insustentáveis aos níveis económico, social e ambiental, o que tem repercussões na nossa saúde e bem-estar. Do crescimento populacional à pobreza e inequidade geradas pelo modelo de “crescimento económico” actual, à perda de biodiversidade e disrupção dos ecossistemas naturais, ao desmesurado crescimento urbano, à poluição e acumulação de desperdícios, às alterações climáticas, ao isolamento individual e à diminuição do capital social na sociedade do consumo: a necessidade de desenvolvimento sustentável e gerador de bem-estar nunca foi tão grande e evidente. Ao longo dos últimos anos têm surgido comunidades intencionais que se organizam segundo princípios de sustentabilidade, como um fenómeno de contra-cultura – as Ecoaldeias (Ecovillages). No entanto, os benefícios para a saúde e bem-estar deste tipo de comunidades não são ainda claros, sendo a experiência de investigação nesta área escassa. O estudo aqui proposto visa conhecer, a título exploratório, os níveis de bem-estar subjectivo em comunidades intencionais que vivem segundo princípios de sustentabilidade em Portugal, se estes níveis são melhores que na população em geral, e quais os factores percebidos que o influenciam. Para tal, terá componentes quantitativas e qualitativas e irá basear-se num questionário auto-administrado aos residentes das Ecoaldeias portuguesas, que inclui o Índice de Bem-estar Pessoal - uma escala de medição do Bem-estar subjectivo validada para a população portuguesa. As suas conclusões poderão contribuir para o desenvolvimento de abordagens mais elaboradas, capazes de edificar uma infra-estrutura teórica para o sistema de conceitos em foco, tão necessária quer a investigações com maior potencial explicativo, quer a decisões com melhor fundamento. ------------ ABSTRACT - Over the past twenty years there has been a growing awareness that the way we live is unsustainable at the economic, social and environmental level, which has impact in our health and wellbeing. From the population growth to poverty and inequity generated by the current model of economic growth, to biodiversity loss and disruption of natural ecosystems, to disproportionate urban growth, to pollution and waste accumulation, to climate change and the individual isolation social loss capital in the consumption society: the need for a development that is sustainable and generates wellbeing has never been greater and more evident. Over the last years intentional communities who live according to principles of sustainability have emerged, has a phenomenon of counter-culture - the ecovillages. The health and wellbeing benefits of this type of communities are not clear, as the investigation in this area is little. The aim of this exploratory study is to know the levels of subjective wellbeing of such communities, in Portugal, if these levels are different from the general population and what are the main perceived contributing factors. This study will have a qualitative and quantitative component and will be based in the application of a self-administered questionnaire that includes the Subjective Wellbeing Index, a measurement scale of subjective wellbeing, validated for the Portuguese population. Its findings may contribute to the development of more elaborate approaches that allow to build a theoretical framework for the system of concepts focused, needed both for further investigations with more explanatory potential, as for more grounded decision-making, to tackle the challenges of sustainable development.

Development and validation of a risk model for prediction of hazardous alcohol consumption in general practice attendees : the PredictAL study

Background: Little is known about the risk of progression to hazardous alcohol use in people currently drinking at safe limits. We aimed to develop a prediction model (predictAL) for the development of hazardous drinking in safe drinkers. Methods: A prospective cohort study of adult general practice attendees in six European countries and Chile followed up over 6 months. We recruited 10,045 attendees between April 2003 to February 2005. 6193 European and 2462 Chilean attendees recorded AUDIT scores below 8 in men and 5 in women at recruitment and were used in modelling risk. 38 risk factors were measured to construct a risk model for the development of hazardous drinking using stepwise logistic regression. The model was corrected for over fitting and tested in an external population. The main outcome was hazardous drinking defined by an AUDIT score >= 8 in men and >= 5 in women. Results: 69.0% of attendees were recruited, of whom 89.5% participated again after six months. The risk factors in the final predictAL model were sex, age, country, baseline AUDIT score, panic syndrome and lifetime alcohol problem. The predictAL model's average c-index across all six European countries was 0.839 (95% CI 0.805, 0.873). The Hedge's g effect size for the difference in log odds of predicted probability between safe drinkers in Europe who subsequently developed hazardous alcohol use and those who did not was 1.38 (95% CI 1.25, 1.51). External validation of the algorithm in Chilean safe drinkers resulted in a c-index of 0.781 (95% CI 0.717, 0.846) and Hedge's g of 0.68 (95% CI 0.57, 0.78). Conclusions: The predictAL risk model for development of hazardous consumption in safe drinkers compares favourably with risk algorithms for disorders in other medical settings and can be a useful first step in prevention of alcohol misuse.

The ABC model for telework in Portugal

The principal aim of this paper is to develop a simple and objective model which can classify an systematise telework, and provide a standard for Portugal. This model defines special concepts of telework and allows the division of the activity in this area, making its application easier. The model was constructed on the basis of four perspectives which it has to cover: the economic and social, of the employers, of the teleworkers and the suppliers of goods and services.
