“…Second, our sample contains both females and males, enabling a deeper understanding of sex differences in the developmental course of eating disorders traits. Previous research suggests that there are differences in genetic and environmental contributions for eating disorders traits between females and males (Baker et al, 2009;Klump et al, 2012;Rojo-Moreno et al, 2017).…”

“…Eating disorder traits are heritable and twin-based estimates of the heritability of EDI total and subscale scores range from 16% to 67% for females and 0% to 47% for males (Baker et al, 2009;Baker, Thornton, Bulik, Kendler, & Lichtenstein, 2012;Keski-Rahkonen et al, 2005;Klump et al, 2012;Klump, McGue, & Iacono, 2000;Rojo-Moreno et al, 2017); the broad ranges likely reflect sample differences including demographic factors such as age and country of origin. Genetic effects on EDI scores become more predominant across childhood in females, specifically in the transition from early to mid-adolescence (Klump, Burt, McGue, & Iacono, 2007).…”

“…The EDI-2 is widely used in Spain and has proven to be widely accepted as a valid instrument for the accurate diagnosis and detection of any eating disorder risk (EA) [31–33] among the Spanish population. We chose to use the EDI-2 based on its good psychometric proprieties in both clinical settings and non-clinical samples, [34] as well as the possibility it offers of separately assessing different dimensions [9,35].…”

Introduction Orthorexia nervosa, a term used to describe an obsession with healthy eating, has been shown to have major health implications for those affected. The aim of this study was to validate a Spanish version of the Düsseldorfer Ortorexie Skala (DOS), a questionnaire for the detection of orthorexic behavior. Methods A cross-sectional study comprising a total sample of 492 Spanish participants recruited from the University of Castilla-La Mancha, Spain, and randomly divided into two groups. The following tools were applied: the DOS and the Eating Disorder Inventory (EDI-2). The factorial structures were analyzed using exploratory and confirmatory factorial analysis. Results The internal consistency of the DOS-ES was α = .841. The exploratory factor analysis has revealed the existence of a single factor with factor loadings ranging from .508 to .802. A confirmatory factor analysis was applied to the second half of the random sample in order to confirm the factor solution. Conclusion The Spanish adaptation of the DOS-ES is proven to be a reliable and valid questionnaire for evaluating the obsessive tendency towards healthy eating among university students.

“…Thus, rates of inheritance-based transmission are between 40 and 88% for anorexia, between 28 and 83% for bulimia, and between 40 and 82% for binge eating disorder (BED) [8]. More recently, the heritability of eating disorders such as anorexia nervosa and bulimia nervosa has been quantified at between 22 and 62% [9]. However, if reviewing certain studies performed from a gender perspective, it may be concluded that "In girls, the four variables demonstrate a heritability component of 37.7% for ineffectiveness, 42.8% for perfectionism, 56.9% for the drive for thinness and 65.5% for body dissatisfaction.…”

Mass Media, Social Networks, and Eating Disorders: Image, Perfection, and Death

Eating - Pathology and Causes

Eating disorders are complex and have multiple causes, which may be genetic, biological, or psychological. Social factors are also relevant. In today’s societies, mass media and social networks play a fundamental role, acting as risk factors for eating disorders. This chapter analyzes the concept of image, differentiating between certain concepts such as reality, perception, and image. Image and self-image are difficult to differentiate and do not always coincide with the body object; one’s self-image may deteriorate to the point that it no longer coincides with the actual body. The mass media may serve as an instrument for the creation of reality. The images of women that are portrayed, especially in the media, tend to be based on sexist stereotypes that saturate social networks, video games, and movies. Currently, pro-ana and pro-mia websites promote identities based on unhealthy diets, exercise, and purgative practices. Therefore, pro-eating disorder socialization exists on Twitter and thinspiration image share is found on Instagram and other social networks.
