Anabolic steroid use and body image psychopathology in men: Delineating between appearance- versus performance-driven motivations

The relationship between anabolic androgenic steroid use and body image, eating behavior, and physical activity by gender: A systematic review

The prevalence of anabolic androgenic steroids (AAS) is rising, especially in recreational sports and the general population. While body image significantly influences AAS use, gender differences remain unclear. We examined gender-related connections between AAS use, body image, eating behavior, and physical activity. Following PRISMA guidelines, we analyzed 22 studies: 14 with male-only samples, 5 mixed-gender, 2 with sexual and gender minorities, and 1 with a female-only sample. FINDINGS: confirm body image as a key predictor of AAS use. Though AAS use correlates with eating disorders, outcomes vary by context; for instance, no discernible difference in eating behavior was observed between AAS users and non-users in bodybuilding. Physical activity findings varied, with some studies showing no significant differences between AAS users and non-users. Due to limited gender-comparison studies, conclusive gender-related differences cannot be drawn. This systematic review underscores the complex interplay between AAS use, body image, eating behavior, and physical activity, emphasizing the necessity for further research to develop targeted interventions for diverse populations, addressing AAS-related concerns and promoting overall well-being.

Causal factors in childhood and adolescence leading to anabolic-androgenic steroid use: A machine learning approach

Background

Prior research has demonstrated associations between anabolic-androgenic steroid (AAS) use and features from several childhood and adolescent psychosocial domains including body image concerns, antisocial traits, and low levels of parental care. However, prior approaches have been limited by their focus on individual features and lack of consideration of the relevant causal structure.

Methods

We re-analyzed data from a previous cross-sectional cohort study of 232 male weightlifters aged 18-40, of whom 101 had used AAS. These men completed retrospective measures of features from their childhood and early adolescence, including body image concerns, eating disorder psychopathology, antisocial traits, substance use, and family relationships. Using an approach informed by principles of causal inference, we applied four machine-learning methods - lasso regression, elastic net regression, random forests, and gradient boosting - to predict AAS use.

Results

The four methods yielded similar receiver operating curves, mean area under the curve (range 0.66 to 0.72), and sets of highly important features. Features related to adolescent body image concerns (especially muscle dysmorphia symptoms) were the strongest predictors. Other important features were adolescent rebellious behaviors; adolescent feelings of ineffectiveness and lack of interoceptive awareness; and low levels of paternal care.

Conclusions

Applying machine learning within a causally informed approach to re-analyze data from a prior study of weightlifters, we identified six factors (most prominently those related to adolescent body image concerns) as proposed causal factors for the development of AAS use. Compared with the prior analyses, this approach achieved greater methodologic rigor and yielded stronger and broader findings.

'The day you start lifting is the day you become forever small': Bodybuilders explain muscle dysmorphia

Muscle dysmorphia (MD) is a pathological preoccupation with muscularity characterised by negative body image, compulsive behaviours, and obsessive thoughts. Since its first identification academics have suggested that it is caused by sociocultural factors. Despite this there has been very little research exploring the role of sociocultural factors in the development and maintenance of MD, and no research that examines MD from within its cultural context. Instead the medical model of MD has dominated understanding. This model presents professionals as the experts on this disorder, and sufferers as pathological individuals in need of expert treatment. This renders cultural context largely irrelevant to understandings of MD. In this paper we present a different kind of expertise with regards MD. We describe the expertise of those most likely to suffer from MD, and upon whom medical descriptions of MD are based: bodybuilders. Specifically, we describe how bodybuilders explain MD (their definition, theory of aetiology and experience of MD, as well as their suggested management strategies), and compare these explanations to the dominant medical model. Through a consideration of the expertise of bodybuilders we break the tunnel vision of medicine, and suggest ways we can move beyond our current under-developed understanding of MD. This paper examines MD from within its cultural context, and in so doing it lays the foundation for a sociocultural explanatory model of MD. If we are to significantly reduce the harms of this disorder we cannot rely solely on treating the few individuals who present to clinicians. Rather we must develop ways to help sufferers to manage their disorder, and to prevent the development of this disorder among those at risk in the first place. To do this we must understand the sociocultural dimensions of MD, and collaborate with bodybuilding communities.

Investigating anabolic-androgenic steroid dependence and muscle dysmorphia with network analysis among male weightlifters

BACKGROUND

Anabolic-androgenic steroid (AAS) dependence has numerous adverse health consequences, and may be driven in part by body image concerns, primarily muscle dysmorphia. This study aims to further understand and identify potential clinical targets using network analyses of AAS dependence and muscle dysmorphia symptoms in males who used AAS and weightlifting controls.

METHODS

A sample of 153 men who currently or previously used AAS and 88 weight-lifting controls were recruited through social media and relevant online forums, and via posters and flyers distributed in select gyms in Oslo, Norway. Symptoms of AAS dependence and muscle dysmorphia were assessed using clinical interviews and standardized questionnaires. Severity of muscle dysmorphia symptoms were compared between the groups using independent samples t-tests. The following symptom networks were computed using Gaussian graphical modeling or mixed graphical modeling: (1) AAS dependence symptoms among men with AAS use (2) muscle dysmorphia symptoms among men with AAS use and weight-lifting controls in two separate networks, which were compared using a network comparison test, and (3) AAS dependence and muscle dysmorphia symptoms among men with AAS use.

RESULTS

In a network of AAS dependence symptoms, continuing use despite physical and mental side effects, using longer than planned, tolerance, and work/life interference were the most central symptoms. When comparing symptom structures of muscle dysmorphia between those who used AAS and controls, the most central symptoms in each group were exercise dependence and size/symmetry concerns, respectively. Men with AAS use demonstrated elevated muscle dysmorphia symptoms compared to controls, indicating that both the severity and structure of symptoms differ between these groups. In a network including both AAS dependence and muscle dysmorphia symptoms, no significant connections between symptom groups were identified.

CONCLUSIONS

AAS dependence is complex, with correlated somatic and psychological challenges driving the symptom network, indicating that alleviating physical and mental health concerns during both AAS use and cessation is an important clinical target. Muscle dysmorphia symptoms related to taking action (diet, exercise, and supplement use) appear to cluster together more for those who use AAS than those who do not.

Clustering psychopathology in male anabolic-androgenic steroid users and nonusing weightlifters

INTRODUCTION

Prior research has demonstrated that personality disorders and clinical psychiatric syndromes are common among users of anabolic-androgenic steroids (AAS). However, the prevalence, expression, and severity of psychopathology differ among AAS users and remain poorly understood. In this study, we examine the existence of potential clinically coherent psychopathology subgroups, using cluster procedures.

METHODS

A sample of 118 male AAS users and 97 weightlifting nonusers was assessed using the Millon Clinical Multiaxial Inventory-III (MCMI-III), measuring personality disorders and clinical syndromes. Group differences in MCMI-III scales were assessed using Wilcoxon-Mann-Whitney tests and Fisher's exact test. Agglomerative hierarchical clustering was used to identify clusters based on MCMI-III scale scores from the whole sample.

RESULTS

AAS users displayed significantly higher scores on all personality disorder (except narcissistic) and clinical syndrome scales compared to nonusing weightlifters. The clustering analysis found four separate clusters with different levels and patterns of psychopathology. The "no psychopathology" cluster was most common among nonusing weightlifters, while the three other clusters were more common among AAS users: "severe multipathology," "low multipathology," and "mild externalizing." The "severe multipathology" cluster was found almost exclusively among AAS users. AAS users also displayed the highest scores on drug and alcohol dependence syndromes.

CONCLUSIONS

AAS users in our sample demonstrated greater psychopathology than the nonusing weightlifters, with many exhibiting multipathology. This may pose a significant challenge to clinical care for AAS users, particularly as there appears to be significant variation in psychopathology in this population. Individual psychiatric profiles should be taken into consideration when providing treatment to this group.

SIGNIFICANT OUTCOMES

As a group, AAS users displayed markedly greater psychopathology than nonusing weightlifters. Multipathology was common among AAS users. Four different subgroups of personality profiles were identified with distinct patterns of pathology and severity.

LIMITATIONS

The cross-sectional nature of the study precludes inferences about causality. The study is limited by possible selection bias, as participants choosing to be involved in research may not be entirely representative for the group as a whole. The study is vulnerable to information bias, as the results are based on self-report measures and interviews.

Associations between body image patterns and body image-related pathology in sexual minority individuals: A mixture-modeling approach

Body image concerns are associated with disordered eating, body dysmorphic disorder (BDD), and illicit appearance and performance enhancing drug (APED) misuse. Sexual minority individuals are a vulnerable population for body image concerns. Latent profile analyses were used to identify body image patterns in sexual minority men (n = 479) and women (n = 483) and to investigate associations between latent profiles and body image-related pathology. A 5-profile solution demonstrated best fit for men and a 4-profile solution for women. Among women, co-occurring high thinness/muscularity concerns had higher probability of vomiting and dietary restriction than the high thinness/low muscularity concerns profile. The probability of driven exercise did not differ across latent profiles for men and only differed between low thinness/low muscularity and high thinness/high muscularity concerns profiles in women. Men with low thinness/high muscularity concerns had significantly lower probability of vomiting and laxative misuse than all other profiles but did not significantly differ from co-occurring high or moderate thinness/muscularity concerns profiles in binge eating and illicit APED misuse. This study may have implications for future research, treatment, and prevention of body image-related pathology in sexual minority individuals.

The Liver King Lie: Misrepresentation, justification, and public health implications

It is well-established that performance and image enhancing drugs (PIEDs) are effective in increasing muscle mass and strength. PIEDs are unique in that, while harm may result from use, there is little evidence of widespread individual or social harm comparable with other illicit substances. However, given the rapid growth of the online health and fitness industry, the digital consumption of hardcore fitness content represents a space ripe for indirect harms. A poignant example of this trend among the digital health and fitness community is the contestation around 'fake natty' users, who falsely claim to not use PIEDs. The non-disclosure of use has the potential to give individuals who are not enhanced the false impression that they too can achieve a bodily ideal which is similar, potentially resulting in psychological distress and risky behaviours. In this commentary, we discuss this harmful phenomenon using the case study of the fitness influencer Brian Johnson, more commonly known as Liver King. Employing a psycho-criminological lens, we use Social Identity Theories to understand the 'Primal' identity, before unpacking Johnson's disavowal of his PIED consumption through Sykes and Matza's (1957) techniques of neutralization. We conclude with an overview of the harms surrounding fake natural influencers and cognitive dissonance, before attempting to map a path towards emic harm reduction in collaboration with the digital fitness community.

Body Weight Dissatisfaction and Health Risk Behaviors in Adolescents

Body weight dissatisfaction has been described as a marker for various health diseases, given its direct association with social, physical, and emotional suffering. We investigated the association between body weight dissatisfaction and health risk behaviors in adolescents. This was a cross-sectional study conducted with 668 adolescents aged 14-19 years in the city of São José, southern Brazil. Body weight satisfaction/dissatisfaction was assessed using a questionnaire validated for the investigated population. Health risk behaviors included smoking, alcohol, illicit drugs, medication, non-prescription anabolic steroids, not using seatbelt, unsafe sexual behavior and not knowing how to deal with day-to-day stress. Among males, 66.1% were dissatisfied with their body weight (32.1% due to thinness and 34.0% due to overweight). Among females, 80.0% were dissatisfied with their body weight (24.5% due to thinness and 55.5% due to overweight). There were no significant differences regarding health risk behaviors according to body weight satisfaction/dissatisfaction and sex. Compared to males who were satisfied with their body weight, those who were dissatisfied due to being overweight were more likely to be using tobacco (OR: 2.9; 95% CI: 2.1-4.2), alcohol (OR: 1.7; 95% CI: 1.5-1.9) and anabolic steroids (OR: 2.7; 95% CI: 1.2-5.7). Compared to females who were satisfied with their body weight, those who were dissatisfied due to thinness were more likely to be consuming alcoholic beverages (OR: 1.6; 95% CI: 1.2-2.0) and less likely to be consuming illicit drugs (OR: 0.5; 95% CI: 0.3-0.8). Interventions aimed at health education regarding the non-adoption of risk behaviors such as alcohol and tobacco use, as well as the non-use of anabolic steroids, and favoring the maintenance of general health, may be important for adolescents with body dissatisfaction. These data suggest that health risk behaviors such as adolescent male use of tobacco, alcohol, and anabolic steroids and the use of alcohol and drugs by female adolescents can be related to body weight dissatisfaction.

Anabolic-Androgenic Steroid Use: Patterns of Use among a National Sample of Canadian Adolescents and Young Adults

Background

Androgenic-anabolic steroid (AAS) use is relatively common among international recreational and community samples and is associated with several deleterious side effects and health consequences that have not been studied recently among a large Canadian sample. Therefore, the purpose of this study was to assess and describe characteristics of AAS users compared to non-AAS users among a national sample of Canadian adolescents and young adults.

Methods

Data from 2,774 adolescents and young adults from the Canadian Study of Adolescent Health Behaviors were analyzed. Participants were recruited via social media advertisements and completed the survey online. Survey items measured sociodemographics, AAS use, AAS side effects, motives for AAS use, AAS administration, body satisfaction, other illicit substance use, mental health, and violence involvement.

Results

Among the overall sample, 1.6% of participants reported lifetime AAS use, with the majority of users being White, heterosexual males. Most users strived to gain weight, with main motives for AAS use including increased muscularity and strength, and improved appearance. Most AAS users were satisfied with their body compared to non-users. Approximately one in five users had AAS dependence and experienced multiple adverse side effects. Few differences between users and non-users in self-reported mental health were found.

Conclusion

Findings indicate that AAS use among a community sample of Canadian adolescents and young adults is an important health issue, particularly given the relatively high occurrence of AAS dependence and adverse side effects reported by users. Findings support the need for education and intervention efforts from healthcare professionals. Further investigations among Canadian AAS users may provide more insight regarding the unique supports these individuals require.

Appearance and Performance-Enhancing Drugs and Supplements, Eating Disorders Symptoms, Drive for Muscularity, and Sexual Orientation in a Sample of Young Men

In an anonymous online study (N = 824), we investigated the frequency of use of appearance and performance-enhancing drugs and supplements (APEDS) in a sample of young men (15−30 years) in Sweden, along with their self-reported eating disorder (ED) symptoms, drive for muscularity and sexual orientation. A total of 129 participants (16.1%) reported regular use of supplements (at least once a week), including one individual using anabolic steroids (0.1%), while a lifetime use of APEDS was reported by 32.3%. The overlap between those using protein supplements and creatine was large (83.6%). Some symptoms of ED (e.g., dietary restraint, objective binge eating, self-induced vomiting, and excessive exercise) significantly predicted the use of APEDS. In addition, the use of APEDS was significantly predicted by the drive for muscularity. The prediction was stronger for the behavioral component of drive for muscularity (Exponential B = 8.50, B = 2.14, SE = 0.16, p < 0.001, Negelkerke R2 = 0.517) than for its attitudinal component (Exponential B = 1.52, B = 0.42, SE = 0.06, p < 0.001, Negelkerke R2 = 0.088). A significantly larger proportion of those identifying as heterosexual reported using APEDS (34.4%) compared to those identifying themselves as homosexual (25.0%), bisexual (19.2%) or other (23.7%). Overall, our results suggest that the use of APEDS might be more related to the drive for muscularity and sexual orientation than symptoms of ED.

Relationship between Attention to Body Shape, Social Physique Anxiety, and Personal Characteristics of Brazilians: A Structural Equation Model

People can develop eating disorders due to excessive body image concerns. The primary objective of this study was to examine the relationship between attention to body shape, social physique anxiety, and personal characteristics in a sample of Brazilians. The secondary objective was to evaluate the correlation of the constructs with the participants' body composition. First, 1795 individuals (70% female; M_age = 25.5 ± 6.6 years) completed the Attention to Body Shape Scale, the Social Physique Anxiety Scale, and a sociodemographic questionnaire. Then, 286 participants (58% female; M_age = 25.3 ± 5.7 years) underwent a bioimpedance exam to identify body composition. Structural equation modeling was used to estimate the relationship between the variables. The greater the attention to body shape, the greater the expectations of negative physical evaluation and the less comfort with physical presentation. Younger age, female gender, consumption of supplements/substances for body change, restrictive diets, physical inactivity, poor self-assessment of food quality, and overweight/obesity were related to negative body concerns. An expectation of negative physical evaluation was positively correlated with body fat and negatively with muscle mass. Comfort with physical presentation was negatively correlated with fat and positively with muscle. These results can support preventive strategies aimed at reducing eating disorders resulting from body image concerns.

Validation of the Muscle Dysmorphic Disorder Inventory (MDDI) among Italian Women Practicing Bodybuilding and Powerlifting and in Women Practicing Physical Exercise

Studies pertaining to muscle dysmorphia (MD) have concentrated the most on males. However, a new body ideal for women is emerging: a very toned, athletic body with flat, smooth muscles. The emphasis on the level of muscularity represents a contribution to the growth of MD symptoms in women. The aim of this study was to evaluate the factorial structure and psychometric properties of the muscle dysmorphic disorder inventory (MDDI) in two samples of physically active Italian women. One-hundred and sixty-five women practicing non-competing bodybuilding/powerlifting and 353 women practicing physical exercise completed the MDDI and measures of features associated with MD. Findings of the confirmatory factor analysis showed a three-factor structure with acceptable fit and invariant across groups. Omega coefficients revealed adequate internal consistency for all the scales and for the total score of the MDDI. Furthermore, convergent and divergent validity as well as retest reliability emerged to be good. MDDI represents a reliable measure of MD symptoms in physically active Italian women.

Use of appearance- and performance-enhancing drugs and substances is associated with eating disorder symptomatology among U.S. college students

PURPOSE

Body ideals for both men and women are continuing to emphasize muscularity and leanness, which has resulted in the high prevalence of appearance- and performance-enhancing drugs and substances (APEDS) use, particularly among young men. Overall, little research has investigated the individual associations between specific APEDS use and eating disorder symptomatology, including among the high-risk population of young adult college students, which was the aim of this study.

METHODS

Data from the 2020-2021 Healthy Minds Study (N = 7394) were analyzed. Five indicators of lifetime APEDS use were assessed, and a cumulative sum score was constructed. Eating disorder symptomatology was assessed via the SCOFF questionnaire. A total of 14 modified Poisson regression analyses were estimated to determine the association between APEDS use and a positive eating disorder screen among women and men.

RESULTS

Lifetime use of protein supplements and diuretics or water pills were associated with a positive eating disorder screen among both women and men, while use of non-steroid synthetic muscle enhancers was associated with a positive eating disorder screen among men and creatine supplement use was associated with a positive eating disorder screen among women. The risk of a positive eating disorder screen was highest among men who reported use of five APEDS in their lifetime.

CONCLUSIONS

Lifetime use of APEDS is associated with eating disorder symptomatology among a national sample of U.S. college and university students. Prevention and intervention efforts are needed to address the link between these potentially harmful behaviors.

Systems mapping to understand complexity in the association between image and performance enhancing drugs (IPEDs) and harm

BACKGROUND

Effective harm reduction work is needed to prevent and respond to the harms associated with image and performance enhancing drug (IPED) use and the diverse needs of IPED communities. Methods based around understanding and mapping complex systems have previously been applied to advance thinking on a range of complex health issues. We applied a systems perspective to explore factors that contribute to IPED-related harms in the UK and to identify harm reduction priorities.

METHODS

An illustrative systems map was developed based on methods for mapping complex systems with expert stakeholders. Participants in two online workshops debated the important factors contributing to harm amongst people who use IPEDs and helped to refine and clarify the map. Discussions using the map reflected on where in the system intervention is needed and the policy implications.

RESULTS

Stakeholders (n=18) identified 51 distinct factors as being important determinants of IPEDs-related harms, and the connections between them. These were grouped under nine domains that formed this system: identity, cognitive processes, beliefs about risk and harm, health and wellbeing, social environment, beliefs about healthcare, healthcare providers, interventions, and IPED markets. Four harm reduction priorities identified through reflexive discussion included providing a wider range of interventions, improving engagement between the IPED communities and healthcare professionals, new approaches to disseminating information in the community, and early intervention.

CONCLUSION

Systems mapping methods are a useful approach to engage stakeholders to discuss drug use issues. A comprehensive policy response is required to this complex issue that recognises diversity in IPEDs communities, their decision-making, and their intervention and service needs, as current approaches are failing to adequately address important areas of harm. Engaging with a wide range of stakeholders is critical to generate new insights that can help respond effectively to reduce the risk of health harms.

Comparing Different Typologies of Physical Activities With a Focus on Motivation

There are numerous classifications of physical activities (PAs). However, they lack precise grouping criteria and tend to vary according to each author. Among other factors, the individual’s level of motivation is considered an important aspect of PA maintenance. In this study, we aimed to (1) compare several PAs according to intrinsic (Interest, Enjoyment, and Competence) and extrinsic (Appearance, Fitness/Health, and Social) motives and (2) analyze PAs with and without previous grouping to explore which PAs are more similar based on the different motivational subscales. We recruited 1,421 physically active Brazilian participants (mean age = 26.83, SD = 10.49). The participants stated which PA they practiced most frequently, and they answered the revised motivation for PA measure. The data were analyzed with multivariate general linear models and Kruskal–Wallis. We found that some PAs consistently differed from others regarding motivational subscales. For example, participants practicing Walking showed less Interest/Enjoyment and Competence motives than participants engaged in several other PAs. Pilates was highlighted by a particularly low level of Social motivation in comparison to other PAs. Furthermore, using the previously suggested categorization of PAs, we also showed consistent distinctions considering each motivational subscale. Specifically, one group of PA (categorized as more Complex, Team, Vigorous, Hybrid, and Combative) scored higher on intrinsic motivation, while the other group of activities (categorized as more Organized, Individual, Moderate, Strength, and Rhythmic) scored higher on Appearance and Fitness/Health motives. Our results thus provide initial evidence for possible new methods of grouping PA types that can improve maintenance behavior using motivation as a grouping factor.

Appearance and performance-enhancing drugs and supplements, eating disorders, and muscle dysmorphia among gender minority people

OBJECTIVE

Appearance and performance-enhancing drugs and supplements (APEDS) can be used to enhance muscle growth, athletic performance, and physical appearance. The aim of this study was to examine the lifetime use of APEDS and associations with eating disorder and muscle dysmorphia symptoms among gender minority people.

METHOD

Participants were 1653 gender minority individuals (1120 gender-expansive [defined as a broad range of gender identities that are generally situated outside of the woman-man gender binary, e.g., genderqueer, nonbinary] people, 352 transgender men, and 181 transgender women) recruited from The Population Research in Identity and Disparities for Equality Study in 2018. Regression analyses stratified by gender identity examined associations of any APEDS use with eating disorder and muscle dysmorphia symptom scores.

RESULTS

Lifetime APEDS use was common across groups (30.7% of gender-expansive people, 45.2% of transgender men, and 14.9% of transgender women). Protein supplements and creatine supplements were the most commonly used APEDS. Among gender-expansive people and transgender men, lifetime use of any APEDS was significantly associated with higher eating disorder scores, dietary restraint, binge eating, compelled/driven exercise, and muscle dysmorphia symptoms. Any APEDS use was additionally associated with laxative use among gender-expansive people. Among transgender women, use of any APEDS was not significantly associated with eating disorder or muscle dysmorphia symptoms.

DISCUSSION

APEDS use is common and associated with eating disorder and muscle dysmorphia symptoms in gender-expansive people and transgender men, thus highlighting the importance of assessing for these behaviors and symptoms among these populations, particularly in clinical settings.

PUBLIC SIGNIFICANCE

This study aimed to examine APEDS use among gender minority people. We found that 30.7% of gender-expansive (e.g., nonbinary) people, 45.2% of transgender men, and 14.9% of transgender women reported lifetime APEDS use, which was associated with eating disorder and muscle dysmorphia symptoms in transgender men and gender-expansive people. Clinicians should assess for these behaviors in gender minority populations.

Psychometric investigation of the Attention to Body Shape Scale in Brazilian adults

The objectives of the study were to develop a Portuguese version of Attention to Body Shape Scale (ABS), estimate the psychometric properties of the ABS for Brazilian data, and compare the ABS scores between the sexes and the different sample characteristics. The Portuguese version was developed following a standardized protocol. The factorial and convergent validity were evaluated using goodness-of-fit parameters and average variance extracted. Composite reliability and ordinal coefficient alpha were calculated. The invariance of the fitted model was investigated across independent subsamples using multigroup analysis. The scores were compared between variables using two-way ANOVA. A total of 1,056 individuals (71% female) with a mean age of 26.1 (SD=6.4) years participated in the study. Item 3 was removed due to low factor loading. The refined model presented good psychometric properties for the data. Different characteristics contributed to greater attention to body shape. The Portuguese version of the ABS will be useful to investigate attention to body shape in Brazil. The validity and reliability of the data supported the adequacy of the refined model. Specific characteristics influenced attention to body shape, and therefore, should be considered in future protocols.

Appearance and performance-enhancing drugs and supplements (APEDS): Lifetime use and associations with eating disorder and muscle dysmorphia symptoms among cisgender sexual minority people

PURPOSE

Appearance and performance-enhancing drugs and supplements (APEDS) are used to enhance muscle growth, athletic performance, and physical appearance. The aim of this study was to examine the lifetime use of APEDS and associations with eating disorder and muscle dysmorphia symptoms among cisgender sexual minority people.

METHODS

Participants were cisgender sexual minority people (1090 gay men, 100 bisexual plus men, 564 lesbian women, and 507 bisexual plus women) recruited from The PRIDE Study in 2018 who reported lifetime APEDS use and completed the Eating Disorder Examination-Questionnaire (EDE-Q) and the Muscle Dysmorphic Disorder Inventory (MDDI). Regression analyses stratified by gender and sexual orientation examined associations of any APEDS use with EDE-Q and MDDI scores.

RESULTS

Lifetime APEDS use was common across the four groups of cisgender sexual minority people (44% of gay men, 42% of bisexual plus men, 29% of lesbian women, and 30% of bisexual plus women). Protein supplements and creatine supplements were the most commonly used APEDS. Any APEDS use was associated with higher EDE-Q scores on one or more subscales in all sexual minority groups. Further, any APEDS use was associated with higher MDDI Total Scores in all groups; any APEDS use was associated with all MDDI subscale scores in cisgender gay men only.

DISCUSSION

APEDS use is common and associated with eating disorder and muscle dysmorphia symptoms in sexual minority men and women, thus highlighting the importance of assessing for these behaviors and symptoms among these populations in clinical settings.

Implications for Psychological Practice with Sexual Minority Men around Body Image Issues: An Addendum to the APA's Guidelines for Psychological Practice with Boys and Men

In 2018, the American Psychological Association published Guidelines for Psychological Practice with Boys and Men, in which there was only one mention of issues related to body image. This commentary explores the effects of body image concerns on men, with a particular focus on the experiences of sexual minority men. Using minority stress theory as a framework, this article aims to highlight the myriad negative mental and physical health outcomes related to body image concerns and eating disorder symptomatology in sexual minority men. Recommendations are provided to guide psychological practice related to body image concerns in sexual minority men.

Associations between ergogenic supplement use and eating behaviors among university students

Ergogenic supplements to improve athletic performance are commonly used among college athletes, but little is known about their association with eating disorder symptoms. The objective of this study was to examine associations between ergogenic supplement use and disordered eating attitudes and behaviors among university students, and to compare differences by sex. Undergraduate students from 10 top-ranked National College Athletics Association (NCAA) Division I colleges completed an online survey on supplement use, athletic activities, and eating attitudes and behaviors. Among 1633 university students, males (38.9%) reported higher rates of current supplement use than females (15.2%) (p < .001). In linear regression models adjusting for athletic status and body mass index, current supplement use was associated with higher Eating Disorders Examination-Questionnaire (EDE-Q) Global, Shape Concern, and Restraint scores in both males and females. Supplement use was associated with driven/compelled exercise (OR 2.00, 95% CI 1.33-2.99) in males and diuretic (OR 6.39, 95% CI 2.02-20.22) and diet pill use (OR 3.07, 95% CI 1.79-5.27) in females. Results suggest ergogenic supplement use is common in undergraduates and associated with disordered eating attitudes and behaviors. Clinicians should screen for disordered eating behaviors particularly in young adults who use ergogenic supplements.

Using Self-Determination Theory to Define Pathological Exercise

Pathological exercise behavior is pervasive in eating disorder psychopathology, yet minimal treatment guidance exists for extinguishing it as little is known about how to differentiate pathological from healthy exercise. The purpose of this study was to characterize pathological exercise in terms of motivation to increase the specificity with which both pathological and healthy exercise is described and to inform treatment interventions. Latent profile analysis characterized homogenous groups based on exercise motivation in two samples: college women (n = 200) and women with eating psychopathology (n = 211). These profiles were compared on levels of eating and general psychopathology and emotion dysregulation. Three profiles emerged describing sedentary, pathological exercise, and athlete groups in the first sample, and five profiles describing neutral, sedentary, weight loss, athlete, and pathological exercise groups emerged in the second sample. Findings indicate that motivation style is salient in defining pathological exercise and may, therefore, be a clinically useful treatment target.

The Impact of the COVID-19 Pandemic on Male Strength Athletes Who Use Non-prescribed Anabolic-Androgenic Steroids

Background: One sub-population potentially affected by the COVID-19 pandemic are strength athletes who use anabolic-androgenic steroids (AAS). We examined links between disruption in AAS use and training due to the pandemic and mental health outcomes in this population, hypothesising: (a) the pandemic would be linked with reduced training and AAS use; and (b) athletes perceiving greater impact on their training and AAS use would report increases in detrimental mental health outcomes. Methods: Male strength athletes using AAS (N = 237) from 42 countries completed an online questionnaire in May 2020. A sub-sample (N = 90) from 20 countries participated again 4 months later. The questionnaire assessed pre-pandemic and current AAS use and training, alongside several mental health outcomes. Results: At Time 1, most participants perceived an impact of the pandemic on AAS use (91.1%) and/or training (57.8%). Dependent t-tests demonstrated significant reductions in training frequency (t = 7.78; p < 0.001) and AAS dose (t = 6.44; p < 0.001) compared to pre-pandemic. Linear regression showed the impact of the pandemic on training was a significant positive predictor of excessive body checking (B = 0.35) and mood swings (B = 0.26), and AAS dose was a significant positive predictor of anxiety (B = 0.67), insomnia (B = 0.52), mood swings (B = 0.37). At Time 2, fewer participants perceived an impact of the pandemic on AAS use (29.9%) and/or training (66.7%) than at Time 1. Training frequency (t = 3.02; p < 0.01) and AAS dose (t = 2.11; p < 0.05) were depressed in comparison to pre-pandemic. However, AAS dose had increased compared to Time 1 (t = 2.11; p < 0.05). Linear regression showed the impact of the pandemic on training/AAS use did not significantly predict any mental-health outcomes. However, AAS dose was a significant negative predictor of depressive thoughts (B = -0.83) and mood swings (B = -2.65). Conclusion: Our findings showed impact of the pandemic on the training and AAS use, reflected in reduced training frequency and AAS dose. However, whilst we detected some short-term consequential effects on mental health, these did not appear to be long-lasting.

Rethinking enhancement substance use: A critical discourse studies approach

BACKGROUND

We draw on both interdisciplinary enhancement substance use research and critical drug studies scholarship to reconceptualise enhancement substance use. Our critical discourse approach illuminates how a variety of substances are positioned as tools for self-improvement. In reconceptualising enhancement substance use, we ask what different substances can be positioned as providing enhancement? How are they positioned as tools for achieving enhancement or self-improvement goals? What discursive repertoires are employed to achieve these aims?

METHODS

Forty interviews were conducted with people who use substances, such as ayahuasca, psilocybin, cocaine, alcohol, nootropics and non-prescription pharmaceuticals, including Adderall and modafinil. To explore the meanings of and motivations for substance consumption, we apply the sociocognitive approach (SCA) pioneered by Teun van Dijk (2014; 2015) and examine language through the triangulation of cognition, discourse and society. We analyse how different substances are positioned as tools for achieving enhancement or self-improvement goals.

RESULTS

We identify three distinct discursive repertoires that frame substance use as enhancement: the discourse of transformation, the discourse of healing and the discourse of productivity. When accounting for enhancement substance use, our participants employ a number of discursive strategies, including ideological polarisation or 'othering', analogies, examples, maxims, metaphors and figurative speech. We also find evidence of interdiscursivity with most participants drawing on more than one discourse when speaking about how substances are positioned as providing enhancement.

CONCLUSION

We conclude that the concept of enhancement has wider applicability than current understandings allow. We argue that if we reframe all substance use as providing enhancement or achieving a self-improvement goal, we have the potential to destigmatise substance use and eliminate the over-simplistic binaries that surround it.

Use of anabolic-androgenic steroids and other substances prior to and during imprisonment - Results from the Norwegian Offender Mental Health and Addiction (NorMA) study

BACKGROUND

Anabolic-androgenic steroid (AAS) use is associated with health problems and substance use. Substance use is common among inmates. This study aims to estimate lifetime and prison use of AAS and other substances, compare characteristics of groups of inmates, and describe factors associated with AAS use in a national prison population.

METHODS

Data from the Norwegian Offender Mental Health and Addiction (NorMA) Study, a cross-sectional survey of people in prisons, included sociodemographic variables and lifetime and prison use of AAS and other substances. Altogether 1,499 inmates, including 96 (6.4%) women, were divided into three mutually exclusive groups according to lifetime AAS use, non-AAS substance use and no substance use.

RESULTS

Lifetime AAS use was reported by 427 (28.5%) inmates; 6 women and 421 men. Non-AAS substance use was reported by 593 (39.6%) and 479 (31.9%) had never used AAS or non-AAS substances. Compared to the non-AAS substance group, the AAS group reported younger debut ages for nearly all non-AAS substances, higher mean number of non-AAS substances used in their lifetime (8.9, 6.6, p < 0.001), during the six months prior to incarceration (5.2, 3.1, p < 0.001), and during (2.3, 1.3, p < 0.001) imprisonment. Although 120 (8.0%) inmates used AAS during the six months prior to incarceration, only ten continued during imprisonment.

CONCLUSIONS

Lifetime AAS use is common among inmates and may be an indicator of more severe substance use problems. Screening for previous and present AAS use at incarceration and increased staff awareness are needed to tailor treatment approaches appropriately.

Anabolic androgenic steroid abuse in the United Kingdom: An update

Anabolic androgenic steroids (AASs) are prescribed for medical conditions related to low testosterone. Abuse of AASs has surged as they become recognised as potent image enhancement drugs. The primary goal of most abusers is to obtain a more attractive outward appearance. Abuse is complex. There are a vast range of AAS substances illegally available, the nature of their true composition is difficult to evaluate. Users follow dosing patterns which incorporate a number of different AASs, in addition to other pharmaceutical substances believed to complement the desired physical effects or manage unwanted effects. Animal work and medical case reports suggest potential to cause serious hepatotoxicity, plus possible neurotoxicity, nephrotoxicity and damage to the cardiovascular and reproductive systems. As the long-term AASs users reach maturity, further controlled experimentation, with larger sample sizes, is required. Data gathering should be directed towards the most vulnerable group of AAS users, females and adolescent boys.

Muscle building supplement use in Australian adolescent boys: relationships with body image, weight lifting, and sports engagement

Background

The extent and implications of muscle building protein supplement use among adolescents is relatively unknown. This study aimed to describe the prevalence of protein powder, creatine, and anabolic steroid use in a sample of 14–16 year-old boys in Australia, and the predictors of actual use, and intentions to use protein powder.

Methods

Data were obtained from questionnaires with Australian adolescent boys aged 14–16 years from one independent boy’s school in Melbourne (N = 237). Hierarchical linear and logistic regressions were used to determine the predictors of intentions, and actual use of protein powder.

Results

49.8% of boys reported current use of, and 62% intended to use protein powder; 8.4% used creatine, and 4.2% used anabolic steroids. Higher levels of drive for muscularity, participation in weight training, and playing a greater number of sports were significant predictors of higher current use and intentions to use protein powder, but age, BMI, body esteem, and ethnicity were not.

Conclusions

Prevalence of muscle building supplement use was relatively high among this adolescent population. This research has implications for intervention and prevention programs to educate young boys about muscle building supplements to reduce negative physical and psychological health effects of their use.

Comparison of Factors Associated with Disordered Eating between Male and Female Malaysian University Students

Disordered eating is prevalent among university students, especially females. Whilst literature suggests that factors associated with disordered eating may differ according to gender, such an association has not been studied in Malaysia. This cross-sectional study aims to compare factors associated with disordered eating between male and female university students. A total of 716 university students (male: 27.4%; female: 72.6%) were recruited in Kuala Lumpur and Selangor, Malaysia. All participants completed a set of self-administered questionnaires and their body weight and height were recorded. About one in five of the university students (20.3%) were found to have disordered eating. There were more female students (22.9%) disordered eating compared to males (13.3%, χ² = 8.16, p < 0.05). In male students (β = 0.228, p < 0.01), depressive symptoms were the only significant predictor for disordered eating. In females, the strongest predictor was depressive symptoms (β = 0.214, p < 0.001), followed by body size satisfaction (β = -0.145, p < 0.01) and body appreciation (β = -0.101, p < 0.05). These findings suggest that there are gender differences in the factors associated with disordered eating among Malaysian university students. Intervention programmes that address disordered eating should take into account these sex differences and its contributing factors.

Exploring the Progressive Use of Performance Enhancing Substances by High-Performance Athletes

Background: Given implications associated with the use of performance-enhancing substances (PESs), stakeholders must remain informed about usage precipitants and anticipate conditions signaling athlete vulnerability to hazardous exposures. Objectives: To gain deeper qualitative insight into high-level athlete PES usage; explore the variables leading them to escalate their PES use regimens; reveal PES experiences during their careers and, unlike other studies, not to focus exclusively on "doping" as measured by the use of WADA-banned substances. Methods: A macro life course-based framework from which the data could emerge through a thematic coding analysis was utilized. Sixteen narrative life course histories of recently retired high-performance athletes report on the factors impelling their escalation in PES use, including for some, the first use of banned PES. Results: Informant reports, thematically coded, reveal performance maximization urgency to be a central factor in escalating PES use, driven by four variables: Requirements, Opportunities, Influencers and Outcomes. These variables each comprise two key components that stimulate an urgency ecosystem affecting an athlete's proximity to an escalation threshold. Conclusions/Importance: Such a comprehensive investigation of PES use precipitants has not previously been undertaken. Advances in PES use were instantiated by a substantive, sometimes radical and often sudden increase in urgency to improve performance related to output requirements, specific demands, knowledge and access, timing windows, the competitive landscape, loyalty to coaches, efficiency expectations and likelihood of detection. This study informs incremental models of doping, the use of which is encouraged in order to analyze life course narratives to better understand athlete behaviors.

The association between muscle dysmorphia and eating disorder symptomatology: A systematic review and meta-analysis

BACKGROUND AND AIMS

Research shows inconsistent findings about the link between muscle dysmorphia (MD) and eating disorder (ED) symptomatology. The aim of this study is to synthesize the scientific evidence available on this topic, the researchers conducted a systematic review and meta-analysis.

METHODS

The literature search enabled us to identify 39 published articles, which provided 36 independent estimations of the correlation between the two variables.

RESULTS

Our analysis found a positive association between MD and ED symptoms (r₊ = .36; 95% CI = 0.30, 0.41). Moderator analyses showed that the type of sample and the tools for assessing MD and ED were statistically associated with the MD-ED effect sizes. The methodological quality of the studies exhibited a positive, statistically significant association with the MD-ED effect sizes.

CONCLUSIONS

Higher levels of MD were related to greater ED symptomatology, but several study characteristics may moderate the association between the two variables. In this study, we discuss limitations and implications for clinical practice and future research.

Drive for muscularity and disordered eating behaviors and its relationship with anthropometric indicators and physical activity in Mexican adolescent men

PURPOSE

Adolescent men have been identified as a risk population to develop eating disorders and other psychopathologies as drive for muscularity (DM) recently considered as muscularity-oriented disordered eating. It is important to identify risk factors as precursors of these pathologies. The aim of this study was to determine the risk of developing disordered eating behaviors (DEB) and DM and its relationship with anthropometric indicators and physical activity (PA) in adolescent men (high-school students, age 15-19) from Hidalgo, Mexico.

METHODS

A cross sectional, descriptive, and correlational field study was carried out in a non-probabilistic sample of 267 Mexican adolescents aged 15-19 years. Participants completed measures of DM, DEB, and PA. Each subject was weighted and heighted to calculate body mass index (BMI), body fat percentage, and fat-free mass index (FFMI).

RESULTS

Adolescents in the DM risk category (OR 8.28, CI 2.71-25.22) had significantly greater odds of developing DEB, while adolescents with higher BMI scores (OR 1.28, CI 1.14-1.45) tended to be more likely of developing DEB. The results showed that DEB and moderate PA were associated with DM; adolescents who engaged in DEB had an 8.64 times (CI 3.05-24.52) higher risk of developing DM. Participants classified in the category of highest moderate PA (OR 2.66, CI 1.26-5.59) had significantly greater odds of developing DM.

CONCLUSION

Important percentages of the risk of developing DEB and DM were determined in Mexican adolescent men. In agreement with other findings, there were no associations between anthropometric indicators and DM.

Prevalence and Correlates of Disordered Eating Behaviors Among Young Adults with Overweight or Obesity

BACKGROUND

Clinical and community samples indicate that eating disorders (EDs) and disordered eating behaviors (DEBs) may co-occur among adolescents and young adults at a weight status classified as overweight or obese.

OBJECTIVE

To determine the prevalence of EDs and DEBs among young adults at a weight status classified as overweight or obese using a nationally representative sample and to characterize differences in prevalence by sex, race/ethnicity, sexual orientation, and socioeconomic status.

DESIGN

Cross-sectional nationally representative data collected from Wave III of the National Longitudinal Study of Adolescent to Adult Health (Add Health).

PARTICIPANTS

Young adults ages 18-24 years old.

MAIN MEASURES

ED diagnosis and DEBs (self-reported binge eating or unhealthy weight control behaviors including vomiting, fasting/skipping meals, or laxative/diuretic use to lose weight). Covariates: age, sex, race/ethnicity, sexual orientation, weight status, and education.

KEY RESULTS

Of the 14,322 young adults in the sample, 48.6% were at a weight status classified as overweight or obese. Compared to young adults at a weight status classified as underweight or normal weight, those at a weight status classified as overweight or obese reported a higher rate of DEBs (29.3 vs 15.8% in females, 15.4 vs 7.5% in males). Logistic regression analyses demonstrated that odds of engaging in DEBs were 2.32 (95% confidence interval 2.05-2.61) times higher for females compared to males; 1.66 (1.23-2.24) times higher for Asian/Pacific Islander compared to White; 1.62 (1.16-2.26) times higher for homosexual or bisexual compared to heterosexual; 1.26 (1.09-1.44) times higher for high school or less versus more than high school education; and 2.45 (2.16-2.79) times higher for obesity compared to normal weight, adjusting for all covariates.

CONCLUSIONS

The high prevalence of DEBs particularly in young adults at a weight status classified as overweight or obese underscores the need for screening, referrals, and tailored interventions for DEBs in this population.

Pornography use in sexual minority males: Associations with body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life

OBJECTIVE

We examined two hypotheses regarding the potential association of pornography use with body image-related and eating disorder-related psychopathology among sexual minority males (i.e. non-heterosexual males). Our primary hypothesis was that pornography use would be associated with males' body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life impairment; our secondary hypothesis was that the type of pornography, namely, professional versus amateur pornography, which contains idealised and non-idealised (i.e. regular) bodies, respectively, would moderate these associations.

METHODS

A sample of 2733 sexual minority males living in Australia and New Zealand completed an online survey that contained measures of pornography use, body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life.

RESULTS

Almost all (98.2%) participants reported pornography use with a median use of 5.33 hours per month. Multivariate analyses revealed that increased pornography use was associated with greater dissatisfaction with muscularity, body fat and height; greater eating disorder symptoms; more frequent thoughts about using anabolic steroids; and lower quality of life. Effect sizes for these associations were uniformly small. Neither relationship status nor genital dissatisfaction was associated with pornography use. The association between pornography use and thoughts about using anabolic steroids was stronger for viewers of professional pornography than viewers of amateur pornography.

CONCLUSION

The findings suggest that the use of pornography is weakly associated with body dissatisfaction and related variables and that the type of pornography (amateur vs professional) viewed may be a moderating factor in some cases. Within the limits of a cross-sectional study design, these findings may have implications for clinicians who treat individuals with eating disorders, body dysmorphic disorder, anabolic-androgenic steroid dependence and related concerns.

Defining the Construct of Synthetic Androgen Intoxication: An Application of General Brain Arousal

Synthetic androgens (i. e., anabolic-androgenic steroids) are the primary component to the majority of problematic appearance and performance enhancing drug (APED) use. Despite evidence that these substances are associated with increased risk for aggression, violence, body image disturbances, and polypharmacy and can develop a pattern of chronic use consistent with drug dependence, there are no formal definitions of androgen intoxication. Consequently, the purpose of this paper is to establish a testable theory of androgen intoxication. We present evidence and theorize that synthetic androgen intoxication can be defined by a pattern of poor self-regulation characterized by increased propensity for a range of behaviors (e.g., aggression, sex, drug seeking, exercise, etc.) via androgen mediated effects on general brain arousal. This theory posits that androgens reduce threshold for emotional reactivity, motor response, and alertness to sensory stimuli and disrupt inhibitory control over the behaviors associated with synthetic androgen use. These changes result from alteration to basic neurocircuitry that amplifies limbic activation and reduces top-down cortical control. The implications for this definition are to inform APED specific hypotheses about the behavioral and psychological effects of APED use and provide a basis for establishing clinical, legal, and public health guidelines to address the use and misuse of these substances.

Brazilian Photographic Figure Rating Scale for Men: Psychometric Investigation

As a follow-up to an earlier study from this research group involving women, this study examined the reliability and validity of the Brazilian Photographic Figure Rating Scale for Men (BPFRS-M) for evaluating men's body perception and dissatisfaction. In both versions of the Brazilian Photographic Figure Rating Scale (BPFRS), respondents viewed eight photographic images (seven distorted and one accurate) of themselves in standard poses and then offered self-ratings. In both versions, 10 experts assessed content validity and demonstrated high agreement (defined by ratings of 4-5 on a 5-point scale) that BPFRS items measured underlying constructs: and experts showed high (>70%) interrater agreement. For this version, participants were 149 Brazilian men (Mean = 22.4; SD = 2.7 years). Pearson correlations demonstrated convergence between the BPFRS-M and two related scales of men's body image. Positive correlations ( p = .0001) were found between actual and respondent-perceived body mass index (BMI). Test-retest and Kappa Index confirmed temporal stability. The BPFRS-M can accurately and reliably assess body perception and dissatisfaction in young men.

Anabolic steroid use among gay and bisexual men living in Australia and New Zealand: Associations with demographics, body dissatisfaction, eating disorder psychopathology, and quality of life

BACKGROUND AND AIMS

Gay and bisexual men may be at heightened risk for using anabolic androgenic steroids (AAS). Few studies, however, have examined AAS use among gay and bisexual men living in countries outside the United States. In addition, few studies have explored the potential associations of AAS use with body image concerns beyond muscularity, including height and genitals, or with eating disorder symptoms and quality of life. Thus, we examined the associations of AAS use, and of thoughts about using AAS, with body image, eating disorder symptoms, and quality of life among gay and bisexual men living in Australia and New Zealand.

METHODS

A sample of 2733 gay and bisexual men completed an online survey promoted by paid nationwide advertisements to users of geosocial-networking smartphone applications.

RESULTS

The prevalence of AAS use, and of thoughts about using AAS, were 5.2% (95% confidence interval [CI]: 4.4%, 6.1%) and 25.4% (95% CI: 23.8%, 27.1%), respectively. Multivariate analyses revealed that more frequent thoughts about using AAS were associated with being older, taller, and experiencing greater dissatisfaction with muscularity and height, less dissatisfaction with body fat, greater eating disorder symptoms, and lower subjective quality of life. Actual AAS users were more likely to be older, from a non-Australian/New Zealander cultural background, experiencing less dissatisfaction with body fat, and experiencing greater eating disorder symptoms.

CONCLUSIONS

Psychopathology related to body image and eating disorders are associated with AAS use among gay and bisexual men living in Australia and New Zealand.

A Systematic Review of the Effects of Resistance Training on Body Image

The purpose of this systematic review was to identify and appraise the literature that has specifically tested the independent effects of resistance training (i.e., weightlifting) on body image in adults. A comprehensive search of electronic databases PubMed, Scopus, PsycNET, and Web of Science for relevant studies published in peer-reviewed journals through December 2016 was conducted, and PRISMA guidelines were followed. Inclusion criteria were that a study had to be (a) written in English, (b) published in a peer-reviewed journal, (c) conducted an assessment of body image using a validated scale before and after a stand-alone resistance training intervention (i.e., not coupled with another mode of treatment), and (d) excluded participants younger than 18 years. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. A total of 7,324 studies were identified, and 11 were included in this review. The majority (8 of 11) of studies concluded that resistance training can significantly improve multiple dimensions of body image, including body satisfaction, appearance evaluation, and social physique anxiety; however, only 3 studies were considered high quality based on their PEDro score, and several methodological limitations exist. Overall, resistance training seems to have the potential to improve body image in adults, but future high-quality studies with more rigorous testing methods and study designs are needed.

Correlates of muscle dysmorphia symptomatology in natural bodybuilders: Distinguishing factors in the pursuit of hyper-muscularity

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. Eating disorder scores (β=.298), rate of pre-competition weight loss (β=.307) and number of competitions (β=-.257) were significant predictors of MD. The association between the EAT-26 and MDDI underscores the salience of disordered eating pathology in presentations of MD. Supporting this, greater rate of pre-competition weight loss, which may reflect disordered eating practices, is also associated with MD symptomatology. The inverse association of competition experience suggests novice bodybuilders may display increased MD symptomatology.

Anabolic Steroid Misuse Among US Adolescent Boys: Disparities by Sexual Orientation and Race/Ethnicity

OBJECTIVES

To examine the prevalence of anabolic steroid misuse among US adolescent boys as a function of sexual orientation and race/ethnicity.

METHODS

We analyzed boys from the 2015 Youth Risk Behavior Survey (n = 6248; mean age = 16), a representative sample of US high school students. Lifetime prevalence of anabolic steroid misuse was dichotomized as never versus 1 or more times.

RESULTS

Sexual minority boys reported elevated misuse compared with heterosexual boys, within each level of race/ethnicity. Black, Hispanic, and White sexual minority boys reported misuse at approximately 25%, 20%, and 9%, respectively.

CONCLUSIONS

Sexual orientation health disparities in anabolic steroid misuse disproportionally affect Black and Hispanic sexual minority adolescent boys, but more research is needed to understand the mechanisms driving these disparities.
