Muscle dysmorphia

Patrycja Klimek, Tom Hildebrandt
OBJECTIVE: Theoretically, legal supplement use precedes and increases the risk for illicit appearance and performance enhancing drug (APED) use-also referred to as the gateway hypothesis. Little is known about associations between the speed of progression, or gap time, from legal to illicit APED use, and psychological risk factors, such as sociocultural influence, eating disorders, body image disturbance, and impulsivity. METHOD: The sample taken from two studies included 172 active steroid users (n = 143) and intense-exercising healthy controls (n = 29) between the ages of 18 and 60 (M = 34...

OBJECTIVE: The tripartite influence model of body image identifies internalization of societal body ideals as a risk factor for developing body dissatisfaction, and subsequent disordered eating behavior. In men, internalization of two dimensions of body image ideals, thinness and muscularity, is associated with body dissatisfaction and eating concerns. However, it is unknown how thinness and muscularity internalization interact in predicting muscle dysmorphia and disordered eating in men...

Objective: Although research on muscle dysmorphia (MD), a body dysmorphic disorder subtype, has recently increased, the causes and mechanisms underlying this disorder remain unclear. Results from studies examining disorders associated with body image suggest the involvement of self-schema in biasing attention toward specific body information. The present study examined whether individuals at higher risk of MD also display attentional biases toward specific types of body images. Methods: The validated Chinese version of the Muscle Appearance Satisfaction Scale was used to distinguish men at higher and lower risk of MD...

Although body size and shape misperception (BSSM) is a common feature of anorexia nervosa, bulimia nervosa and muscle dysmorphia, little is known about its underlying neural mechanisms. Recently, a new approach has emerged, based on the long-established non-invasive technique of perceptual adaptation, which allows for inferences about the structure of the neural apparatus responsible for alterations in visual appearance. Here, we describe several recent experimental examples of BSSM, wherein exposure to "extreme" body stimuli causes visual aftereffects of biased perception...

The use of ergogenic substances (UES) is not restricted to achieving a better athletic performance, but also it is a behavior for body changing through muscle development; however, little is known about the relationship between muscle dysmorphia (MD) and UES. Therefore, it was conducted a systematic review of those empirical papers that have studied this relationship over the last decade (2004-2014). First it is highlighted that of the 22 articles analyzed, only 13 explicitly aimed this interest. Besides, although the documented data outlined some relevant aspects such as the existence of a high co-occurrence (60-90%) between MD and UES...

The aim of this study is to investigate the relationship between the risk of muscle dysmorphia and psychopathological symptoms in an Italian sample of male bodybuilders. METHOD: The sample was recruited online (145 men with a mean age of 30.0 years) and participants were asked to fill out the Muscle Dysmorphic Disorder Inventory (MDDI), Symptom Cheklist-90-R (SCL-90-R), Dissociative Experiences Scale (DES-II), and to provide other socio-demographic data. Bodybuilders at risk of muscle dysmorphia display greater global psychopathology and present higher scores on all SCL-90-R dimensions when compared to bodybuilders not at risk of muscle dysmorphia...

BACKGROUND: Muscle dysmorphia (MD) is a relatively young diagnosis referring to the desire for a high degree in lean muscle mass, while simultaneously believing that one is insufficiently muscular, mostly found in men. It goes along with a risk for social withdrawal to maintain rigid exercise and dietary regimen. The aim of the current study was thus, to explore differences in men with and without a risk for muscle dysmorphia regarding their desire for social interaction. Furthermore, we investigated potential effects of individual social comparison tendencies (the tendency to compare oneself with persons who are perceived to be superior or inferior to oneself on a certain dimension) and of one's own body schema on the desire for social interaction...

The current study sought to explore sex differences in the presentation of probable full-syndrome and subthreshold body dysmorphic disorder (BDD) in adolescents from an Australian community sample. Specifically, it examined sex differences in the types of BDD symptoms endorsed, body areas of concern, and the association with elevated symptoms of comorbid disorders. In male participants, it also compared the presenting features of those with and without muscle dysmorphia. Of 3,149 adolescents assessed using self-report questionnaires, 162 (5...

Muscle dysmorphia (MD) is characterized by the pathological pursuit of muscularity and leanness, which includes eating- and exercise-related practices. The aim of this cross-sectional study was to identify correlations of MD symptomatology in natural bodybuilders. An online survey assessing diet, supplementation and training practices, and MD and eating disorder symptoms was completed by male bodybuilders with recent experience competing in a drug-tested competition. Sixty participants (age 29.6±7.1 years) completed the survey...

Debido a una distorsión en la imagen corporal, las personas que padecen Dismorfia Muscular se perciben menos musculosas de lo que son en realidad. Con el fin de aumentar su musculatura, algunas de estas personas hacen uso de hormonas cuya función principal es la del aumento del tamaño muscular. Por lo que el objetivo de este estudio es conocer la prevalencia del uso de hormonas en personas afectadas por Dismorfia Muscular. 562 hombres y 172 mujeres fisicoculturistas y levantadores de pesas, a los que se le administraron diferentes cuestionarios para conocer, primero si padecían el trastorno, y después en qué porcentaje usaban hormonas la muestra afectada...

OBJECTIVE: Pressures for men to conform to a lean, muscular ideal have, in part, contributed to eating disorder and muscle dysmorphia symptoms, yet few programs have been developed and empirically evaluated to help men. This study investigated the acceptability and efficacy of a cognitive dissonance-based (DB) intervention in reducing eating disorder and muscle dysmorphia risk factors in men with body dissatisfaction. METHOD: Men were randomized to a two-session DB intervention (n = 52) or a waitlist control condition (n = 60)...

INTRODUCTION: The umbilicus is an important component of body esthetics, and its absence or dysmorphia may give rise to psychological discomfort, making it a common concern in surgical planning. Many techniques of umbilicus reconstruction have been proposed, each with its own limitations in terms of esthetics, risk of stenosis or final positioning. Reconstruction techniques may involve skin grafting, cartilage, purse-string suture and flaps. One of the most promising approaches is scarless neo-umbilicoplasty...

PURPOSE: The purpose of this study was to determine whether the muscle appearance satisfaction scale (MASS) shows acceptable psychometric properties in Mexican bodybuilders. METHODS: A total of 258 Mexican male bodybuilders were recruited. Two self-report questionnaires, including the MASS and drive for muscularity scale (DMS), were administered. Six models of the latent structure of the MASS were evaluated, using confirmatory factor analysis with maximum likelihood, considering robust Satorra-Bentler correction to estimate the fit of the models to the data...

Cornelia de Lange syndrome (CdLS) is a congenital developmental disorder characterized by craniofacial dysmorphia, growth retardation, limb malformations, and intellectual disability. Approximately 60% of patients with CdLS carry a recognizable pathological variant in the NIPBL gene, of which two isoforms, A and B, have been identified, and which only differ in the C-terminal segment. In this work, we describe the distribution pattern of the isoforms A and B mRNAs in tissues of adult and fetal origin, by qPCR (quantitative polymerase chain reaction)...

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...
