I disturbi della nutrizione e dell’alimentazione nei maschi: una panoramica sulle ricerche nel periodo 2007-2017 = Eating disorders in males: An overview of research over the period 2007-2017

Introduction. Despite the extensive literature, the gender differences in eating disorders (ED) have been poorly investigated. Most of the studies, in fact, have been conducted so far on female samples, emphasizing the misleading belief that such disorders are of exclusive relevance of women. Aim. The review aim at highlighting as this preconception is still widespread among the male patients and the clinicians and as it represents an impediment to a correct diagnosis and a proper treatment planning. Method. Included studies were selected in the scientific literature published between January 2007 and December 2017 through the main databases, combining the words: “males”, “eating disorder”, “anorexia nervosa”, “bulimia nervosa”, “binge eating disorder”. Results. Fifty-four studies have been selected in accordance with the followed methodological criteria. Discussion. Only recently, the attention of researchers have been also focused on male population: many differences between genders have emerged in prevalence, onset, phenomenology, diagnosis, comorbidity and outcomes of ED. The studies on risk factors have also pointed out significant differences between males and females, especially in relation to the different weight exerted by psychological variables involved in the aetiology of eating disorders. Conclusions. Compared with a little knowledge of ED in the male population, it is important to widespread the comprehension taking into account the gender perspective. The attention must be paid particularly to critical developmental periods, such as puberty and adolescence, where early detection and prevention of these disorders is of greatest importance, inside a conceptual framework which considers the mutual influence between biological and psychological vulnerability, and sociocultural factors.
