Consumo de álcool e adiposidade abdominal : resultados do estudo longitudinal de saúde do adulto – ELSA Brasil

A acumulação de tecido adiposo abdominal apresenta associação positiva com eventos cardiovasculares, pressão arterial e alterações metabólicas. Dentre os fatores de risco para o aumento da obesidade abdominal está o alto consumo de bebidas alcoólicas, particularmente a cerveja. O objetivo deste estudo foi identificar associação entre consumo de bebidas alcoólicas (CBA) e adiposidade abdominal. Trata-se de uma investigação de corte transversal conduzida a partir da linha de base do Estudo Longitudinal de Saúde do Adulto – ELSA-Brasil, composta por 15.105 indivíduos (35 a 74 anos). Foram analisadas variáveis antropométricas, socioeconômicas e consumo de bebidas alcoólicas e utilizados, para diagnóstico de obesidade abdominal, os pontos de corte da circunferência da cintura (CC) e relação cintura/quadril (RCQ) preconizados pela Organização Mundial de Saúde. O CBA foi categorizado em quintis. Teste de Kolmogorov-Smirnov foi utilizado para avaliar a normalidade das variáveis. A associação entre variáveis antropométricas e o CBA foi avaliada utilizando-se teste Mann-Whitney, Kruskal-Wallis e teste qui-quadrado. Foram testados modelos de regressão linear e Poisson, ajustados por idade, sexo, IMC, tabagismo, atividade física, renda e escolaridade. A CC inadequada foi associada a maior CBA em toda amostra (1,03, IC95% 1,01-1,05) e em homens (1,05, IC95% 1,03-1,08). A RCQ inadequada foi associada a maior CBA tanto para o total da amostra (1,04, IC95% 1,01-1,06) como para mulheres (1,07, IC95% 1,03-1,12). Homens no quinto quintil de consumo de cerveja apresentaram chance 1,05 maior (IC95% 1,02-1,08) de ter a CC inadequada quando comparados aos que se encontravam no primeiro quintil. Já entre as mulheres a chance foi 1,16 (IC95% 1,13-1,20). Homens e mulheres no quinto quintil de consumo de cerveja tinham, respectivamente, 1,03 (IC95% 1,00-1,07) e 1,10 (IC95%1,04-1,15) vezes mais chance de apresentar RCQ inadequada. O consumo de vinho só foi associado a maior chance de ter CC aumentada entre mulheres (β=0,026, p<0,027). Neste estudo, o consumo de álcool foi associado positivamente com obesidade abdominal, sendo mais importante a contribuição da cerveja para aumento da CC e da RCQ.

Cidade-paisagem : novas perspectivas sobre a preservação da paisagem urbana no Brasil

The edification of the landscape in the scientific and social field, in speech as in the method, is taken in this study as a complex process, from which were developed relationships of dominance on the perception of space, which persist strongly consolidated, since the genesis of the conceptual practice till its actual praxis. Historically, the landscape studies took place slowly, immersed in many questions, in face of the multiplicity of meanings that the concept offers. In the psyche, the notion of landscape is present since a long time ago, as an unconscious human being practice, even before any ideological hypothesis formulation. However its materialization in the social conscious will come only from painting, and specially with the perspective, through the technicity of the view, at first wandering the infinity, now ordained in a frame‟. Since then, the landscape is perceived according to the order of the view, as the equivalent of nature and beauty, assuming at the same time, an important symbolic value, since it is linked to mnemonic and subjective processes that the being build with the territory. The domain on this space-cognitive experience, characteristic of the contemporary, consolidates in the social imaginary, building consensus on the landscape, whose aesthetic references make a cultural appeal, very pertinent to the actual capitalist dynamics of production the space worldwide, mainly of the spectacle and commodification of cities promoted by the city marketing. In Brazil, this consensual ideology of the landscape surpass the social imaginary and also dominates the political imaginary, whereas the main instrument for preserving the landscape, Decree-law 25, from November 30, 1937, and its limit to those of exceptional value or remarkable feature. The analysis of the processes for putting under governmental trust for inscription of goods by the landscape value, reveals the dominant, if not exclusive, adoption of selection criteria related to aesthetic aspects. Abstain, therefore, from what the nation considers patrimony , other landscapes that, besides not having, at first, remarkable aesthetic value, play a crucial role as an inheritance from ancestor relations between man and space and pre- existing condition for the same present and future relations. From this historical background, the research seeks to transfer into contemporaneity, the ideological analysis of the concept and its relation with the building of the landscape in the collective imaginary, in order to recognize, in current practices to landscape preservation, as much this genesis, rooted in aesthetics, remains strongly consolidated, feeding the current dynamics of consumption and commodification of the city. Therefore, as preliminary conclusion, one can state that the identification of landscapes of different value, especially aesthetic, maintains and intensify the treatment of the city as an object, a standard‟ commodity to be sold / traded on the world market, in detriment of its recognition as a dynamic process that, even though inserted in the global context, develops specificifities and peculiarities, inherent to the production of space, as Lefebvre preconizes, that is, to the production of life, social product , as characteristic, dissent generator
