Body Image, Binge Eating, and Bulimia Nervosa in Male
Bodybuilders


Gary S Goldfield, PhD1,2, Arthur G Blouin, PhD2, D Blake Woodside, MD3

                  Objective: Male bodybuilders (MBB) exhibit more severe body dissatisfaction, bulimic eating
                  behaviour, and negative psychological characteristics, compared with male athletic and nonathletic
                  control subjects, but few studies have directly compared MBB and men with eating disorders. This
                  study compared men with bulimia nervosa (MBN), competitive male bodybuilders (CMBB), and
                  recreational male bodybuilders (RMBB) on a broad range of eating attitudes and behaviours and
                  psychological characteristics to more accurately determine similarities and differences among these
                  groups.
                  Method: Anonymous questionnaires, designed to assess eating attitudes, body image, weight and
                  shape preoccupation, prevalence of binge eating, weight loss practices, lifetime rates of eating
                  disorders, anabolic androgenic steroid (AAS) use, and general psychological factors, were
                  completed by 22 MBN, 27 CMBB, and 25 RMBB.
                  Results: High rates of weight and shape preoccupation, extreme body modification practices, binge
                  eating, and bulimia nervosa (BN) were reported among MBB, especially among those who
                  competed. CMBB reported higher rates of binge eating, BN, and AAS use compared with RMBB,
                  but exhibited less eating-related and general psychopathology compared with MBN. Few
                  psychological differences were found between CMBB and RMBB.
                  Conclusions: MBB, especially competitors, and MBN appear to share many eating-related features
                  but few general psychological ones. Longitudinal research is needed to determine whether men
                  with a history of disordered eating or BN disproportionately gravitate to competitive bodybuilding
                  and (or) whether competitive bodybuilding fosters disordered eating, BN, and AAS use.

                    Clinical Implications

                    · Bodybuilding among men is associated with an increased risk of body dissatisfaction, weight and shape
                      preoccupation, and pathological eating behaviours.
                    · Compared with RMBB, CMBB are more likely to engage in binge eating and meet criteria for BN
                      during their lifetime
                    · CMBB are also at higher risk of using AAS, compared with RMBB, but the high prevalence of use in
                      RMBB indicates the use of steroids for cosmetic reasons.

                    Limitations

                    · A clinical sample of eating disorder patients and a community-based sample of MBB comprised the
                      overall sample. The differences in recruitment may have biased the results.
                    · Diagnostic criteria for BN was established by self-report without a confirmatory clinical interview;
                      thus, the prevalence and severity of binge eating and abnormal weight control practices may be
                      overestimated or underestimated.
                    · The sample of MBB was relatively small; therefore, results may not represent the studied populations.

                 Résumé : L’image corporelle, l’alimentation excessive et la boulimie chez les
                 culturistes masculins
                 Objectif : Les culturistes masculins (CM) présentent une insatisfaction corporelle, un
                 comportement alimentaire boulimique et des caractéristiques psychologiques négatives plus graves,
                 comparés à des sujets témoins masculins athlétiques et non athlétiques, mais peu d’études ont
                 comparé directement les CM avec des hommes souffrant de troubles alimentaires. Cette étude a
                 comparé des hommes souffrant de boulimie (HB), des hommes culturistes de compétition (HCC) et
                 des hommes culturistes récréatifs (HCR) relativement à une vaste gamme d’habitudes et de
                 comportements alimentaires, et de caractéristiques psychologiques pour déterminer plus
                 précisément les similitudes et les différences entre ces groupes.
                 Méthode : Des questionnaires anonymes, destinés à évaluer les habitudes alimentaires, l’image
                 corporelle, les préoccupations de poids et de forme, la prévalence des épisodes d’alimentation
                 excessive, les méthodes de perte de poids, les taux à vie de troubles alimentaires, l’utilisation de
                 stéroïdes anabolisants androgéniques (SAA), et les facteurs psychologiques généraux ont été
                 remplis par 22 HB, 27 HCC, et 25 HCR.
                 Résultats : Des taux élevés de préoccupations de poids et de forme, des méthodes extrêmes de
                 modification du corps, des épisodes d’alimentation excessive et la boulimie ont été déclarés par les
                 HC, en particulier par ceux qui étaient en compétition. Les HCC ont déclaré des taux plus élevés
                 d’épisodes d’alimentation excessive, de boulimie et d’utilisation de SAA, comparativement aux
                 HCR, mais présentaient moins de psychopathologie liée à l’alimentation et générale,
                 comparativement aux HB. Peu de différences psychologiques ont été observées entre les HCC et les
                 HCR.
                 Conclusions : Les HC, surtout les compétiteurs, et les HB semblent partager de nombreux traits liés
                 à l’alimentation, mais peu de caractéristiques psychologiques. Une étude longitudinale est
                 nécessaire pour déterminer si les hommes ayant des antécédents d’alimentation déréglée ou de
                 boulimie s’adonnent à la compétition culturiste de façon disproportionnée, ou si le culturisme de
                 compétition favorise l’alimentation déréglée, la boulimie et l’utilisation de SAA.
