The sport of competitive bodybuilding requires an intense regimen of weightlifting and dieting, often aided with muscle-building or fat-burning drugs, and culminating in an on-stage posing competition. Despite these rigorous demands, competitive bodybuilding is popular, with thousands of competitions performed annually around the world. Although many studies have addressed the psychological features of various sports and the athletes who compete in them, few have examined the psychological aspects of bodybuilding. Even fewer studies have specifically examined competitive bodybuilders, as opposed to the much larger group of "recreational" bodybuilders who do not compete. The limited available literature suggests that competitive bodybuilders may show an increased risk for four categories of psychopathology: muscle dysmorphia, eating disorders, abuse of appearance- and performance-enhancing drugs, and exercise dependence. However, in each of these categories, one must carefully distinguish between the planned and dedicated behaviors required for success in the sport, as opposed to frankly pathological behaviors that impair social or occupational function, cause subjective distress, or lead to adverse health consequences. Future work should attempt to better assess the nature and prevalence of these conditions among competitive bodybuilders, with perhaps greatest attention to the issue of drug use.

The article offers information on body dysmorphic disorder (BDD), a psychiatric condition characterized by engrossment with a perceived deficiency in one's appearance. It states that BDD has similar features with the obsessive-compulsive spectrum. It also responds to its treatments such as serotonergic antidepressants and cognitive-behavioral therapy. It adds that muscle dysmorphia is a form of BDD in which males become preoccupied with their insufficient masculine appearance.

The article presents a study that determined if anabolic-androgenic steroids (AAS) have deleterious effects on the cardiac functions of their users. The study involved weightlifters as respondents comprising of 12 admitted long-term AAS users and 7 who are not. Participants are of similar age and have similar exercise levels. Results of the study revealed that the AAS users have striking impairment of cardiac contraction and relaxation, expressing similar symptoms of cardiomyopathy compared with the non-users.

The demonstration that 2 disorders coaggregate in families is often the first step in the exploration of genetic factors common to the 2 disorders. Previous methods of analyzing familial coaggregation have used either (1) a typical measure of association (eg, the odds ratio) between a disorder in an individual and another disorder in family members, or (2) a linear structural equation model (SEM). The association method accommodates case-control sampling of families, but may not assess the causal effect of interest because it is not based on an underlying causal model. The SEM method is based on a causal model, but cannot easily accommodate case-control sampling or direct effects of 1 disorder on the other within individuals. We develop a new method of analyzing coaggregation based on directed acyclic graphs. Because this method is a generalization of structural equation models and uses measures of association that accommodate case-control sampling and direct effects, it combines the strengths of both previous methods. In the absence of direct effects between disorders, our approach provides a valid estimate of the causal coaggregation effect. In the presence of direct effects, our approach provides an upper-bound estimate and (assuming additive linear effects of latent familial and nonfamilial factors) a lower-bound estimate of the causal coaggregation effect. For illustration, we applied our method to a family study of binge eating disorder and bipolar disorder. [ABSTRACT FROM AUTHOR]
