The relationship between anabolic androgenic steroid use and body image, eating behavior, and physical activity by gender: A systematic review. Neurosci Biobehav Rev 2024; 163:105772. [PMID: 38879097 DOI: 10.1016/j.neubiorev.2024.105772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2024] [Revised: 05/30/2024] [Accepted: 06/12/2024] [Indexed: 06/25/2024]
Abstract
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.

Abstract
Background Chronic pain's influence on emotional well-being can be significant. It may evoke feelings of despair, frustration, nervousness, and melancholy in individuals, which often manifest as reactions to enduring pain and disruptions in their daily lives. In this study, we seek to perform Bootstrap Exploratory Graph Analysis (EGA) on the Persian Version of the Perth Alexithymia Questionnaire (PAQ) in a cohort of people with chronic pain. Methods The research concentrated on the population of individuals encountering chronic pain within Tehran province from 2022 to 2023. Ultimately, the analysis comprised information from 234 male participants (with a mean age of 30.59, SD = 6.84) and 307 female participants (with a mean age of 30.16, SD = 6.65). After data collection, statistical analysis was conducted using the EGAnet2.0.4 package in R.4.3.2 software. Results The outcome of bootstrapped EGA unveiled a two-dimensional configuration of the PAQ comprising Factor 1 denoted as negative difficulty in describing and identifying feelings (N-DDIF) and Factor 2 characterized as general-externally orientated thinking (GEOT), representing robust structural integrity and item consistency (all items have stabilities > 0.70). Conclusion These findings endorse the validity of the PAQ, as evidenced by its confirmation in a broader sample using a novel methodology consistent with existing literature on two-factor decentering models.

Abstract
The Eating Disorder Examination-Questionnaire (EDE-Q) is a widely used self-report measure of eating pathology. Despite widespread use, investigations of its factor structure have proved inconclusive and rarely supported the "original" interpretation. The current study evaluates several proposed factor solutions of the EDE-Q using latent variable analysis in a sample of adult women with anorexia nervosa (AN). A total of 804 patients from a specialist treatment center in the United States participated in the study. Confirmatory factor analysis was conducted on 22 EDE-Q items assessing attitudinal features of eating pathology. Findings suggested that three full-item versions (none of which was the "original" interpretation) fit the data adequately, with a brief, seven-item version showing excellent fit. The study is one of the first to examine this within a sample of women with AN and provides an empirical foundation for how best to use the EDE-Q among clinical and research participants with AN. Findings suggest that the "original" factor structure lacks structural validity in women with AN. Its use should generally be discouraged, and future work on screening and treatment outcomes might consider the EDE-Q7.

Abstract
The Intuitive Eating Scale-2 (IES-2) is a measure of intuitive eating behaviors that has been extensively validated, with traditional latent variable modeling approaches, in youth and adults from many different populations, including college students in China. However, there is still a lack of research on the psychometric properties of the IES-2 in adults from the Chinese general population. Moreover, psychometric network analysis, as a complement to traditional latent variable modeling approaches, has not been used for examining the psychometric properties of the IES-2. Thus, the present study used a psychometric network approach to evaluate the psychometric properties of the IES-2 in Chinese adults from the general population. A sample of 700 Chinese general adults (50% women; Mage = 31.13 years, SD = 9.19) recruited online were included in the present study. Psychometric network analysis was performed. Exploratory graph analysis (EGA) identified four dimensions, which were well separated in the estimated network. The network structure showed excellent stability and metric measurement invariance (i.e., network loadings) across men and women. Furthermore, several items on the IES-2 were identified as key nodes in the network of the IES-2 that may be important for the development and maintenance of intuitive eating. For example, two items (i.e., "I trust my body to tell me when to eat," and "I trust my body to tell me when to stop eating") related to reliance on body cues were the most impactful nodes in the complete network. The findings of our study provide a greater understanding of the IES-2 from the perspective of network analysis and have implications for applications of intuitive eating interventions for general populations.

Abstract
BACKGROUND Eating disorders are seen mainly as a problem affecting women, not just by the public at large, but also in specialized circles. Although it is true that more women than men suffer from all types of eating disorder, pertinent reviews have clearly shown that they do indeed occur in men, and that the available evidence on the matter is limited. The stigmatization of men with eating disorders makes it harder for these men, and for the relevant professionals, to recognize the symptoms and to seek or provide help. METHODS This review is based on publications retrieved by a selective search in PubMed on the epidemiological, diagnostic, clinical, and therapeutic aspects of eating disorders in men. RESULTS Current estimated lifetime prevalences in men are 0.2% for anorexia nervosa, 0.6% for bulimia nervosa, and 1% for bingeeating disorder; the corresponding figures for women are 1.4%, 1.9%, and 2.8%. Men and women may display different manifestations. Women are thought to be mainly seeking a slim figure and weight reduction; men, a muscular build. The established Germanlanguage screening and diagnostic tools, however, do not cover the types of symptoms that are more common in men. Little is known about whether treatment yields comparable results in men and women. CONCLUSION It is important to combat the stigmati - zation of men with eating disorders and to remove the obstacles to their appropriate diagnosis and treatment. The current methods of screening and diagnosis need to be adapted to take account of the special aspects of abnormal eating behavior in men. It remains unclear whether and how the disorderspecific treatment of these conditions in men should differ from their treatment in women.

Abstract
Introduction Decentering describes the ability to shift the focus away from one's subjective experience onto the experience itself. The Experiences Questionnaire (EQ) is a self-report measure that was developed to systematically assess changes in Decentering ability. Although several studies show the validity of the questionnaire, there are discrepancies between the factorial structure of the Decentering scale of the EQ (EQ-D) found in the initial study (one factor) and other studies (two factors). Therefore, the current study aimed to assess the dimensionality of the EQ-D using Exploratory Graph Analysis (EGA). Methods In total, 1,100 participants were recruited online (790 female, 307 male, 3 non-binary; age 18 to 65 years). Participants completed the EQ and the Rosenberg Self-esteem scale (RSES). Results The bootstrapped EGA results revealed a two-dimensional structure of the EQ-D (Factor 1: Distanced Perspective, DP; Factor 2: Accepting Self-perception, AS) with high structural and item stability (all items > 0.70). The two dimensions of the EQ-D showed a high internal consistency (DP: ω = 0.74; AS: ω = 0.86) and discriminant validity with the rumination items of the EQ. Furthermore, a high convergent validity of the EQ was established, as the AS factor exhibited a significantly stronger correlation with self-esteem than the DP factor (z = 7.98, p < 0.001), which aligns with theoretical considerations suggesting that the AS factor encompasses aspects of self-compassion alongside decentering. We also found measurement invariance of the DP and AS factor across age, gender and country but not for education. Discussion These results support the EQ's validity, demonstrated in a larger sample with a new methodology, aligning with existing two-factor decentering models literature.
