Go big or go home: A thematic content analysis of pro-muscularity websites.

Existing content analyses of pro-eating disorder web content have focused on thinness-oriented eating disorder pathology. With the increasing prevalence of muscularity-oriented body image concerns, we conducted a systematic content analysis of 421 active pro-muscularity websites including static content websites, blogs, and online forums. Emergent coding methods were utilized (Cohen's kappa range=.78-.88), and eight distinct thematic categories were identified: rigid dietary practices (26.2%), rigid exercise rules (18.4%), the broader benefits of muscularity (16.1%), the encouragement of the drive for size (15.9%), the labeling of non-ideal body (11.4%), marginalizing other areas of life (6.1%), muscle enhancing substances (3.3%), and minimizing medical risk (2.6%). Pro-muscularity websites provide explicit material surrounding potentially non-healthful muscularity-oriented eating and exercise practices. Clinician awareness of the potentially non-healthful behaviors involved in the pursuit of muscularity may enhance the detection and treatment of male eating disorders, in particular.
