RESUMEN
Background: Muscle dysmorphia or vigorexia is a disorder in which a person becomes obsessed with the idea that he or she is not muscular enough. Aim: To assess physical exercise, eating behaviors and the presence of muscle dysmorphia among weightlifters and medical students. Subjects and Methods: Cross sectional evaluation of 88 male weightlifters aged 27 ± 7 years and 84 male medical students aged 22 ± 1 year was made. Eating behaviors were evaluated using the Eating Attitudes Test (EAT-40) and the Eating Disorders Inventory (EDI). The perception of body image was assessed using the Graduate Hannover Scale (GHS). Results: Prevalence of muscle dysmorphia among weightlifters was 13.6 percent. Both groups did not differ in body dissatisfaction. Interest in appearance among weightlifters was significantly higher than in students and ranged significantly higher in EAT-40 and EDI (p < 0.001). Other sports were practiced with the same frequency by weightlifters and students. Weightlifters expended more time than students exercising to improve their appearance (p < 0.005). Forty two percent of weightlifters with muscle dysmorphia displayed abuse of anabolics and 67 percent used other substances to improve their performance (p < 0.005). Conclusions: The presence of muscle dysmorphia among weightlifters was confirmed. They were dissatisfied with their body image and more concerned with their physical appearance than those without muscle dysmorphia and/or students. Their anabolic abuse rate was high. Our findings were similar to those reported in the international literature.
