Muscle Dysmorphia Symptomatology: A Cross-Cultural Study in Mexico and the United States

This cross-cultural study examined the nature and correlates of muscle dysmorphia (MD) in Mexicans who lift weights, compared symptomatology in Mexicans to that in Americans, and investigated the roles of bodybuilding and acculturation in the presentation of MD symptoms. The sample consisted of 46 Mexicans and 67 Americans who lift weights (N = 113). Participants completed measures regarding symptoms of MD, engagement in bodybuilding, acculturation, exercise dependency, eating pathology, and steroid use. Contrary to predictions, results indicated similar occurrences of MD symptoms in both samples. MD symptoms were correlated with bodybuilding, exercise dependence and eating pathology in both Mexican and American men, as well as American women. Engagement in bodybuilding in men was similar in both samples; however, in the American sample, bodybuilding behaviors were more related to MD. Acculturation to American culture was not related to symptoms of MD. Steroid use was greater in both samples than in previous studies. Findings are discussed in terms of cross-cultural and clinical implications.
