ABSTRACT
A Systematic review of articles from peer-reviewed journals was conducted, studying the complete texts in all cases. The key words selected were: "Eating Disorders" and "Internet." Descriptive analysis was performed on the variables selected, and Fisher's Exact test was used to analyze the presence of a linear relationship between qualitative variables. Of the 7 studies reviewed, 5 (71.42%) focused on content criteria and 2 (28.57%) examined both documentary and content criteria. Documentary quality was evaluated using two assessment instruments developed by two of the authors, comprising a set of 20 different variables, 5 of which were common to both studies (25% observed percentage agreement). Fisher's Exact test revealed significant differences between the two questionnaires (p = 0.049). Studies assessing Website content used 30 different topics to classify the subject matter, of which 6 were common to 2 studies. Although generic instruments for assessing the quality of Websites devoted to eating disorders were found, no validated questionnaire was found. This research did not locate any checklist or simple tool which could be used by consumers of health information available on the Web.
Revisão sistemática de artigos provenientes de periódicos com revisão por pares, estudando os textos completos em todos os casos. Os Descritores selecionados foram:"Transtornos Alimentares" e "Internet". A análise descritiva foi realizada para as variáveis selecionadas, e o teste exato de Fischer foi usado para analisar a presença de uma relação linear entre variáveis qualitativas. Dos 7 estudos revistos, 5 (71.42%) enfocaram critérios de conteúdo e 2 (28.57%) examinaram tanto critérios documentais e de conteúdo. A qualidade documental foi estudada usando-se dois instrumentos de avaliação desenvolvidos por dois dos autores, compreendendo um conjunto de 20 variáveis diferentes, 5 das quais eram comuns a ambos estudos (25% de percentagem de concordância observada). O teste exato de Fisher revelou significantes diferenças entre os dois questionários (p = 0.049). Apesar de terem sido encontrados instrumentos genéricos para avaliar a qualidade de sites dedicados a transtornos alimentares, nenhum questionário validado foi observado. A pesquisa nem mesmo localizou qualquer checklist ou simples ferramenta que poderia ser utilizada por consumidores de informação em saúde disponível na rede.

La presencia cada vez mayor de las bases de datos especializadas y su uso generalizado, así como las posibilidades de difusión que las nuevas tecnologías ofrecen, obliga a un análisis pertinente de los documentos. Los lenguajes de indización nacen a raíz del crecimiento de la información generado por la revolución científica, como una forma rápida y normalizada de procesar, almacenar y recuperar los contenidos documentales. Este trabajo examina las características y ventajas de los lenguajes documentales en la era digital describiendo ejemplos de tesauros, y sus correspondientes relaciones jerárquicas, aplicados a los trastornos de la conducta alimentaria.
The increased presence and widespread use of specialized databases, as well as the possibilities for distribution offered by new technologies, require a pertinent method for analyzing documents. Indexing languages emerge from the information growth generated by the scientific revolution as a quick, standardized way to process, store and retrieve document contents. This paper examines the characteristics and advantages of documentary languages in the digital age, describing examples of thesauri and their corresponding hierarchical relationships as applied to eating disorders.
