Men may have a later onset of ED because pubertal changes are later than those observed in women ( Salas et al., 2011).ДЇor all the above, it is important to have standardized instruments that allow an early detection of EDs and is necessary to take a test that provides information on the risks in normal populations, especially adolescents, and also, in young adult populations, in whom high rates of maintenance of EDs are observed ( Treasure et al., 2011). It was identified that the age of greatest risk of developing ED would be 16 years in women and 17 years in men ( Zapata et al., 2018). In turn, a high-risk factor is the initiation of unsupervised diets at an early age, especially in overweight or obese young people, who have shown greater DT and body dissatisfaction (BD) ( Contreras et al., 2015). (2011) observed significant differences between adolescents who attended public schools, showing a greater drive for thinness DT than those who attended private schools. (2006) described that EDs have become chronic and, in recent years, have spread to men and different socioeconomic levels. Due to the changes in the DSM-5 diagnostic criteria, there has been an increase in AN and BN and a decrease in diagnoses not specified (EDNOS) or other diagnoses (OSFED) ( Lindvall Dahlgren et al., 2017). In bulimia nervosa (BN), it would appear before the age of 24 years. The age of onset of EDs is earlier in anorexia nervosa (AN), on average before the age of 22 years. An important study carried out with a sample of 36,309 people in the United States ( Udo and Grilo, 2018) indicates that the ED would be linked to a significant deterioration in psychosocial functioning and that there were relevant associations between binge ED and extreme obesity, which, together with the high prevalence, would constitute a major public health problem. The increase in point prevalence in the period studied was 3.5% between 20 and 7.8% between 20. The authors also incorporated 27 other studies that revealed that the mean point prevalence of any ED is 19.4% in women and 13.8% in men. When analyzing by continent, it stands out that America has the highest point prevalence mean, with 4.6%.

The weighted means of the point prevalence and their ranges were 5.7% for women and 2.2% for men. The mean prevalence in the last year and its range corresponded to 2.2% for women and 0.7% for men. A recent systematic review ( Galmiche et al., 2019), which includes 94 studies published in English or French, between 20, shows that the mean lifetime prevalence of EDs and their ranges in women was 8.4% and in men 2.2%. The best fit indices were obtained by the ESEM two-bifactor model, with twelve specific factors corresponding to the EDI-3 subscales and two general orthogonal factors (i.e., risk subscales and psychological subscales), consistently with the theoretical basis.Д®ating disorders (EDs) are serious psychological problems, with high mortality and poor prognosis, strongly associated with thinness typical ideal of contemporary western societies ( American Psychiatric Association, 2014). Results: A majority of the subscales presented alphas and omegas equal to or greater than 0.70, with the exception of asceticism (О± = 0.543, П‰ = 0.552) and interpersonal alienation (О± = 0.684, П‰ = 0.695) scales, which are consistent with the values of the Spanish and Mexican non-clinical samples. (2020), evaluating four additional models that included bifactor exploratory structural equation modeling (ESEM), bifactor, and two-bifactor. The reliability and factorial structure of the instrument were analyzed, replicating the confirmatory factor analyses of Brookings et al. Methods: The sample consisted of 1,091 Chilean adolescents and young people (i.e., 476 men and 615 women) between 15 and 28 years old, from the metropolitan region, and four regions from the coast and south-central zone of the country. The aim of this study was to analyze the psychometric properties of the Eating Disorder Inventory (EDI)-3 test to evaluate eating disorders in young Chilean population.
