Muscle dysmorphia

Daniel Sturman, Ian D Stephen, Jonathan Mond, Richard J Stevenson, Kevin R Brooks
Although research addressing body size misperception has focused on socio-cognitive processes, such as internalization of the "ideal" images of bodies in the media, the perceptual basis of this phenomenon remains largely unknown. Further, most studies focus on body size per se even though this depends on both fat and muscle mass - variables that have very different relationships with health. We tested visual adaptation as a mechanism for inducing body fat and muscle mass misperception, and assessed whether these two dimensions of body space are processed independently...

PURPOSE: Robust empirical evidence has illustrated a rising prevalence of body dissatisfaction and disordered eating among males, noting that both may be oriented more toward muscularity-as opposed to thinness-oriented concerns. While an elevated prevalence of premorbid anorexia nervosa (AN) has been noted among those with muscle dysmorphia, little evidence has examined the process of this transition from thinness-oriented to muscularity-oriented disordered eating. METHODS: This clinical observation presents a case of AN in an adolescent male, whose symptom presentation transitioned during the course of treatment for AN, into more muscularity-oriented disordered eating...

Since 1997, there has been increasing research focusing on muscle dysmorphia, a condition underpinned by people's beliefs that they have insufficient muscularity, in both the Western and non-Western medical and scientific communities. Much of this empirical interest has surveyed nonclinical samples, and there is limited understanding of people with the condition beyond knowledge about their characteristics. Much of the existing knowledge about people with the condition is unsurprising and inherent in the definition of the disorder, such as dissatisfaction with muscularity and adherence to muscle-building activities...

BACKGROUND: Many factors can influence an athlete to consume dietary supplements, such as age, sex and sports, among others. Few studies regarding the prevalence and associated factors are available for athletes, especially in developing countries. OBJECTIVE: The aim of the study was to determine the factors associated with the consumption of dietary supplements among Brazilian athletes. MATERIAL AND METHODS: This is a cross-sectional study involving 182 athletes of both sexes...

Challenges to epidemiological studies of eating and related body image disturbance disorders in males include, in addition to low base rates and the predominance of residual diagnostic categories, the female-centric nature of current classification schemes and the consequent lack of appropriate assessment instruments. In this narrative review, we summarise epidemiological data regarding the prevalence and correlates of eating disorders, related body image disturbance disorders, and eating disorder features in males...

OBJECTIVE: Anabolic androgenic steroid (AAS) use has been robustly associated with negative body image, and eating- and muscularity-oriented psychopathology. However, with AAS being increasingly utilized for both appearance and athletic performance-related purposes, we investigated whether comorbid body image psychopathology varies as a function of motivation for usage. METHOD: Self-reported motivation for current and initial AAS use was recorded amongst 122 AAS using males, alongside measures of current disordered eating and muscle dysmorphia psychopathology...

This study examined the mediating role of self-oriented and socially prescribed perfectionism in the relationship between sociocultural influences (i.e., media, peer, and teasing) and symptoms of muscle dysmorphia (MD) and eating disorders (ED). A nonclinical sample of males (N = 158, Mage = 26.94, SD = 5.50) completed measures of perfectionism, MD, body dissatisfaction, drive for thinness, and bulimia. Susceptibility to appearance-based messages from the media, their peers, and family was also measured. Analyses confirmed the partial mediating role of self-oriented perfectionism only for drive for thinness...

BACKGROUND: Muscle dysmorphia (MD) is associated with a self-perceived lack of size and muscularity, and is characterized by a preoccupation with and pursuit of a hyper-mesomorphic body. MD symptoms may hypothetically be more prevalent in bodybuilders (BBs) than in non-bodybuilder resistance trainers (NBBRTs). OBJECTIVE: Our objective was to compare MD symptomatology in BBs versus NBBRTs and identify psychological and other characteristics associated with MD in these groups...

OBJECTIVE: To determine the prevalence of body dysmorphic disorder (BDD) and muscle dysmorphia (MD) in enlisted U.S. military personnel; and secondarily, to determine supplement use and relationship with BDD and MD. METHODS: A survey of advanced individual training of tri-service personnel at Fort Sam Houston, Texas, was performed combining the dysmorphia concern questionnaire, the MD symptom questionnaire, a supplement questionnaire, and demographic factors. RESULTS: Of the 1,320 service members approached, 1,150 (87...

BACKGROUND: Body dysmorphic disorder (BDD) is a condition associated with a perceived defect or flaw in physical appearance and repetitive behaviours related to this perceived imperfection. BDD affects men and women approximately equally, although a variant called muscle dysmorphia occurs more frequently in males. OBJECTIVE: The aim of this article is to provide general practitioners (GPs) with information related to the identification and management of individuals with BDD, especially males...

OBJECTIVES: (1) To collect, analyze and synthetize the evidence on muscle dysmorphia diagnosis as defined by Pope et al. and (2) To discuss its appropriate nosology and inclusion as a specific category in psychiatric classificatory systems. METHOD: A systematic search in the MEDLINE, the PsycNET, the LILACS and SciELO databases and in the International Journal of Eating Disorders was conducted looking for articles published between January 1997 and October 2014 and in EMBASE database between January 1997 and August 2013...

OBJECTIVE: Studies using traditional screening instruments tend to report a lower prevalence of eating disorders (EDs) in men than is observed in women. It is therefore unclear whether such instruments are valid for the assessment of ED in males. Lack of a formal diagnostic definition of muscle dysmorphia syndrome (MD) makes it difficult to identify men at risk. The study aimed to assess the prevalence of ED and MD in male university students of Buenos Aires. METHOD: A cross-sectional, two-stage, representative survey was of 472 male students from six different schools in Buenos Aires, mostly aged between 18 and 28 years...

Research suggests that peer muscularity norms preferences are related to men's body image, but little information is known about how perceptions of specific peer group norms preferences are related to men's body image disturbances and specific health behaviors. This study investigated how men perceived the muscularity preferences of male, female, close, and distant peers and whether the perceptions of specific peer preferences were related to muscle dysmorphia and steroid use. Data on muscle dysmorphia and the perceptions of peer muscularity norms were collected from 117 male college students...

The use of anabolic-androgenic steroids (AASs) by professional and recreational athletes is increasing worldwide. The underlying motivations are mainly performance enhancement and body image improvement. AAS abuse and dependence, which are specifically classified and coded by the DSM-5, are not uncommon. AAS-using athletes are frequently present with psychiatric symptoms and disorders, mainly somatoform and eating, but also mood, and schizophrenia-related disorders. Some psychiatric disorders are typical of athletes, like muscle dysmorphia...

Muscle dysmorphia (MD) is the distorted perception of men's own muscle appearance. The increasing popularity of weightlifting in Chinese men suggests the presence of MD. The study assessed the validity and reliability of the Muscle Appearance Satisfaction Scale (MASS) for its use on adult Chinese males. Exploratory and confirmatory factor analyses of responses from 225 and 592 participants confirmed the same five factors for the 17-item Chinese version as the original MASS (CFI=.931, RMSEA=.052). The internal consistency for all factors were acceptable (Cronbach's α=...
