Abstract
Eating disorders are serious psychological disorders with an increased incidence in last years. One of the factors that determine the high prevalence of eating disorders in our society is the lack of knowledge about nutrition. One of the reasons of this lack of knowledge could be the presence of online resources without scientific validity. OBJECTIVE AND SCOPE: The aim of this study was to analyze the scientific quality and positioning of websites in Spanish that have information on nutrition, eating disorders and obesity. For this purpose, a web search was conducted in the Google Chrome browser using the key words: diet, anorexia, bulimia, obesity and nutrition, and selecting the first 20 results of each search at the rates offered by SeoQuake positioning (Page Rank, Alexa Rank y SEMrush Rank). The variables used for the analysis were: information related to eating habits and diets, information on healthy eating, information about eating disorders and their diagnostics, and formative information about general health topics with professional criteria. Only the 50% of the webpages accomplished the inclusion criteria for this study. Most of them did not follow the guidelines established by e- Europe assessment for quality. The median of the Webpage's PageRank was 2, except those associated with health institutions. Given the scarcity of healthcare websites with scientific rigor is essential to review the existing one and to create new online spaces whose supervision must be carried out by specialists in health and nutrition.
