Aim: This study examines the prevalence of eating disorders, particularly anorexia and bulimia nervosa, among middle-aged Spaniards, noting their rising incidence in men as well as women. It explores how these disorders relate to sociodemographic factors and lifestyle habits.
Methods: A cross-sectional survey was conducted from August 2020 to November 2021 via online platforms. Participants were Spanish nationals aged 31-50 years residing in Spain.
Results: Out of 9913 respondents, 96.66% reported no diagnosed eating disorders, while 3.34% reported one or more (0.36% anorexia nervosa; 0.53% bulimia nervosa; 1.97% other eating disorders; 0.48% multiple disorders). Concerns about body image and lack of control over food intake were reported by 50% and 28%, respectively, suggesting potential undiagnosed disorders. Significant BMI differences were noted between healthy individuals and those with anorexia or bulimia.
Conclusions: Anorexia and bulimia affect both adolescents and middle-aged individuals, challenging existing stereotypes. The high prevalence of undiagnosed eating disorder behaviors highlights the need for early detection. To address these issues in Spain, targeted awareness programs are essential to reduce stigma and improve service access through clinical, social, and political collaboration.
