Linking body esteem to eating disorders among adolescents: A moderated mediation model

Personal risk factors and types of sport associated with drive for thinness and drive for muscularity in NextGen athletes

Introduction

Professional and student-athletes are at risk of developing symptoms of eating disorders (ED), including drive for thinness and muscularity due to personal risk factors (e.g., low self-esteem) and sport-specific characteristics (e.g., sport requirements). However, limited studies have focused on ED symptoms among NextGen athletes (identified in Canada as élite or relève) who compete at the provincial, national, and international levels but are not yet part of national teams. As such, they have access to fewer financial resources and support from their sport federations, which can create additional stress for these athletes. The present study aimed to identify personal risk factors and types of sports associated with (a) drive for thinness and (b) drive for muscularity in NextGen athletes.

Methods

These athletes (n = 254) aged between 14 and 25 years old completed an online questionnaire. Perfectionism, self-esteem in sport, drive for thinness, and drive for muscularity were, respectively, assessed by the Multidimensional Inventory of Perfectionism in Sport, the Sport State Self-Esteem Scale, the Eating Attitude Test-26, and the Drive for Muscularity Scale. Other personal risk factor (e.g., athletic status) were measured using in-house questions. Each personal risk factor was included in two multiple linear regressions, respectively, to determine which factors were most associated with drive for thinness and drive for muscularity.

Results

Analyses revealed that perfectionist aspirations during training were linked to a stronger desire for thinness. In addition, not being in school or not having a job were also linked to a stronger desire for thinness. Several variables were found to be associated with a greater desire for muscularity: being a male athlete, playing team sport, weight category sport or endurance sport (as opposed to esthetic sport), having elite status, being less satisfied with one's current sporting performance and having higher perfectionist aspirations during training.

Discussion

This study offers initial insights into the factors influencing EDs among NextGen athletes, which provides a foundation for deeper exploration and the creation or modification of targeted interventions. These findings can guide sport organizations in creating guidelines and programs to better support the next generation of national athletes (e.g., create programs to help athletes maintain investments outside).

Body Image and High-Risk Weight and Shape Control Behaviors Among Transgender and Nonbinary Young Adults: The Role of Sexual Assault

Purpose: Transgender and nonbinary (TNB) populations experience disproportionate rates of sexual assault. Despite evidence from cisgender samples linking sexual assault exposure to body image concerns and disordered eating behaviors, such as weight and shape control behaviors (WSCBs), little is known about these relationships in TNB people. The purpose of this study was to assess associations among past-year sexual assault exposure, body areas satisfaction, body weight esteem, and high-risk WSCBs in a sample of TNB young adults. Methods: A sample of 714 participants completed a cross-sectional online survey. Multivariable linear and logistic models were fit to determine associations between constructs of interest. Natural effects mediation analyses assessed for potential mediation of the relationship between sexual assault and WSCBs by body areas satisfaction and body weight esteem. Analyses were stratified by three gender identity categories. Results: Past-year sexual assault exposure was associated with significantly decreased body areas satisfaction, but only for nonbinary participants. No significant association was found between sexual assault and body weight esteem. Sexual assault was associated with significantly increased risk for WSCBs across gender identity categories. No mediation of these relationships by body areas satisfaction and body weight esteem was observed. Conclusion: Findings support clinical consideration of WSCBs in TNB survivors of sexual assault. Results suggest that multiple factors, including body image and sexual assault, may contribute separately to disordered eating behaviors in TNB young adults.

The Effect of Appearance Anxiety on Social Anxiety among College Students: Sequential Mediating Effects of Self-Efficacy and Self-Esteem

Social anxiety is a serious psychological problem prevalent among Chinese college students, and appearance anxiety plays an important role in its development. Although some studies have explored the relationship between the two, the mediating mechanism is unclear. This study constructed a sequential mediation model based on the cognitive-behavioral theory of body image disorder and social phobia to explore the mediating role of self-efficacy and self-esteem. A total of 234 college students were recruited using the convenience sampling method, including 68 males (29.10%) and 166 females (70.90%), with an average age of 21.25 years (SD = 1.75). Data were collected using the Social Appearance Anxiety Scale, the General Self-Efficacy Scale, the Self-Esteem Scale, and the Interaction Anxiety Scale. The study's results demonstrated a significant and positive predictive relationship between appearance anxiety and social anxiety (effect = 0.21, SE = 0.04, 95% CI = [0.13, 0.29], p < 0.001). Appearance anxiety not only directly affects social anxiety but also has three indirect paths affecting social anxiety: the independent mediating effect of self-efficacy (effect = 0.03, SE = 0.01, 95% CI = [0.00, 0.06], p < 0.001), the independent mediating effect of self-esteem (effect = 0.03, SE = 0.02, 95% CI = [0.01, 0.07], p < 0.001), and the serial mediation effect of self-efficacy and self-esteem (effect = 0.01, SE = 0.01, 95% CI = [0.00, 0.03], p < 0.001). Direct and indirect effects accounted for 73.81% and 26.19% of the total effect, respectively. These findings provide new perspectives on the intervention with and treatment of social anxiety in college students.

Associations between sex differences, eating disorder behaviors, physical and mental health, and self-harm among Chinese adolescents

BACKGROUND AND AIM

Eating Disorders (ED) result in impaired well-being, but there exist an insufficient number of studies that have focused on the influence of sex and sexual orientation disparities within ED behaviors. Thus, we aimed to investigate ED behaviors among male and female adolescents with different sexual orientations in a school sample to understand prevalence and correlates of different ED behaviors.

METHOD

Data was analysed from 11,440 Chinese school adolescents with a mean age of 14.74 years (SD = 1.46). Reported data was gathered on sociodemographic information including sexual orientation, ED behaviors, health factors (reported health, cognitive function), mental health factors (depression, anxiety, suicidal ideation, non-suicidal self-injurious behavior), and social functioning (school bully victimization, and school bully perpetration). Logistic regression models were used to estimate the associations with ED behaviors, using the heterosexual orientation as the reference group as they are the majority.

RESULTS

Compared to female adolescents, male adolescents reported lower anxiety symptoms (t = - 12.39, p < 0.001, Cohen's d = - 0.233), were more likely to be the perpetrator of school bullying (χ² = 190.61, p < 0.001, φ = 0.129), and reported a lower likelihood of taking dietary restriction (χ² = 290.08, p < 0.001, φ = 0.160). Overall, the prevalence of dietary restriction presented sex disparities. Adolescents who reported no sexual attraction were less likely to engage in ED behaviors. Using heterosexual orientation as the reference group, the group who reported no sexual attraction was associated with lower risk in dietary restriction and purging in both male and female adolescents. Using the heterosexual orientation as the reference group, female sexual minority groups were at high risk of ED behaviors, with bisexual orientation and gay/lesbian orientation having a higher likelihood of engaging in objective binge eating.

CONCLUSIONS

The results revealed significant sex and sexual orientation differences of ED behaviors. The study suggests that adolescents is a period of sexuality development and could be critical for understanding adolescents' eating behaviors. It is important to guide adolescents to healthy eating during their development and considerations should be made by clinicians when creating interventions for ED behaviors among the different sex and sexual orientation groups.

The Effect of Social Appearance Anxiety on the Online Impulse Purchases of Fashionable Outfits Among Female College Students During Pandemic Periods: The Mediating Role of Self-Control and the Moderating Role of Subjective Socioeconomic Status

Purpose

With the rise of social media, an increasing number of young females have focused more attention on their body image, leading to social appearance anxiety. Thus, the current study aimed to investigate a moderated mediation model of social appearance anxiety and online impulse purchases of fashionable outfits through self-control moderated by subjective socioeconomic status during the pandemic.

Methods

A total of 1651 female college students (Age = 17-24, M_age = 19.30, SD = 1.14) with more than one month of closed-off management experience completed self-report questionnaires concerning social appearance anxiety, self-control, online impulse purchases of fashionable outfits, and subjective socioeconomic status.

Results

After controlling for the potential influence of coronavirus stress, the results indicated that social appearance anxiety was positively related to online impulse purchases of fashionable outfits among female college students during the pandemic, mediated by self-control. Furthermore, subjective socioeconomic status moderated the indirect link between social appearance anxiety and the online impulse purchase of fashionable outfits. Specifically, subjective socioeconomic status buffers the negative effect of social appearance anxiety on self-control and the risk effect of low self-control on the online impulse purchases of fashionable outfits.

Implications

The current study deepens the research on the relationship between social appearance anxiety and online impulse purchases during pandemic periods; meanwhile, it provides evidence for preventing excessive online impulse purchases of fashionable outfits among young females.

ADRA2B and HTR1A: An Updated Study of the Biogenic Amine Receptors Reveals Novel Conserved Motifs Which Play Key Role in Mental Disorders

Mental disorders are strongly connected with several psychiatric conditions including depression, bipolar disorder, schizophrenia, eating disorder, and suicides. There are many biological conditions and pathways that define these complicated illnesses. For example, eating disorders are complex mental health conditions that require the intervention of geneticists, psychiatrists, and medical experts in order to alleviate their symptoms. A patient with suicidal ideation should first be identified and consequently monitored by a similar team of specialists. Both genetics and epigenetics can shed light on eating disorders and suicides as they are found in the main core of such investigations. In the present study, an analysis has been performed on two specific members of the GPCR family toward drawing conclusions regarding their functionality and implementation in mental disorders. Specifically, evolutionary and structural studies on the adrenoceptor alpha 2b (ADRA2B) and the 5-hydroxytryptamine receptor 1A (HTR1A) have been carried out. Both receptors are classified in the biogenic amine receptors sub-cluster of the GPCRs and have been connected in many studies with mental diseases and malnutrition conditions. The major goal of this study is the investigation of conserved motifs among biogenic amine receptors that play an important role in this family signaling pathway, through an updated evolutionary analysis and the correlation of this information with the structural features of the HTR1A and ADRA2B. Furthermore, the structural comparison of ADRA2B, HTR1A, and other members of GPCRs related to mental disorders is performed.

Symptom association between social anxiety disorder, appearance anxiety, and eating disorders among Chinese University students: A network analysis to conceptualize comorbidity

Background

Incidences of social anxiety disorder (SAD), appearance anxiety, and eating disorders (ED) show an increased prevalence among young people. However, symptoms' associations between these disorders have not been investigated in depth. Network analysis is an approach that can be used to explain the relationship(s) between symptoms of different psychological disorders. Using network analysis, this study aimed to explore the association and potential interacting mechanisms between SAD, appearance anxiety, and ED.

Methods

This study included 96,218 University students from Jilin Province, China. SAD, appearance anxiety and ED were assessed using the Social Anxiety Subscale of the Self-Consciousness Scale (SASS), the Appearance Anxiety Scale Brief Version (AASBV), and the Sick, Control, One, Fat, Food questionnaire (SCOFF), Chinese versions. Network analysis was employed to investigate the symptom associations, while the stability of the network model was analyzed using statistical measures.

Results

The prevalence of ED among the total sample was 38% (95% CI: 38.1-38.8%), while this figure was 31.2% (95% CI: 30.7-31.6%) in males and 43.6% (95% CI: 43.2-44.0%) in females. Additionally, the total score of SAD was significantly higher in females (11.83 ± 5.37) than it in males (10.02 ± 5.46) (P < 0.001). While the total score of appearance anxiety was also different significantly in gender (39.21 ± 9.49 in females vs. 38 ± 9.42 in males) (P < 0.001). Results showed that ED was associated with all three aspects of appearance anxiety, including "appearance concern," "appearance satisfaction," and "wish for good looks." Appearance anxiety and SAD were also associated; specifically, symptoms of "appearance satisfaction" were significantly associated with the symptoms "easily talk to strangers" and "appearance concern", which was also significantly associated with "embarrassed". Compared with males, females showed significantly stronger associations with appearance anxiety symptoms, while ED symptoms were associated with "troubled by being watched" and "appearance concern".

Conclusion

Appearance anxiety was associated with both ED and SAD symptoms. ED may have a potential relationship with SAD, affecting appearance anxiety indirectly. Significant differences were found among males and females in symptom associations between appearance anxiety and SAD. This study therefore clarified that young people should have body-positive interventions and challenge the normative body image discourse, which may help alleviate symptoms of SAD and ED.

Association between high levels of body-esteem and increased degree of midcingulate cortex global connectivity: A resting-state fMRI study

Multiple neuroimaging studies have examined the neural underpinnings of body image disturbances in patients with eating disorders. However, key brain regions related to body image, such as body-esteem (BE), among healthy individuals are understudied. Given the extremely crucial role of BE in eating behaviors and physical and mental health, the current study conducted data-driven analysis and characterized the neurobiological correlates of BE with the network properties of the resting brain using the voxel-wise degree centrality (DC) measures of resting-state functional magnetic resonance imaging (rs-fMRI) data and seed-based resting-state functional connectivity (RSFC). A total of 694 healthy young adults (females = 474, mean age = 18.38 years, range = 17-22) underwent rs-fMRI, and completed the Body-Esteem Scale for Adolescents and Adults, the Eating Disorder Diagnosis Scale, and the Restraint Scale. After correcting for differences in age, gender, body mass index, and head motion, whole-brain correlation analyses revealed that a high level of BE was associated with increased DC within the right midcingulate cortex (MCC) and subsequent high levels of MCC-based RSFC strengths. Furthermore, MCC connectivity patterns related to BE were inversely associated with disordered eating behaviors. These findings suggest that adaptive cognitive and emotional regulation (i.e., self-evaluation and emotion based on body image) may explain the potential relationship between MCC connectivity patterns and BE to a certain extent. As such, future studies should investigate these interesting possibilities.

The Relationship between Body Dissatisfaction and Eating Disorder Symptoms in Young Women Aspiring Fashion Models: The Mediating Role of Stress

It is widely recognized that body dissatisfaction is an important public health concern. In the past, being a fashion model was almost synonymous with anorexia/bulimia, and even today, there are cases of eating disorders in young women whose ambition is to become a top model. Moreover, stress can play a substantial role within ill health via related behaviors such as smoking, substance abuse, and inappropriate eating. In our study, we examined 112 aspiring fashion models aged between 15 and 24 years (M = 19.5, SD = 2.08) from 32 different countries of the world during an international contest, and 100 students (control group), aged between 16 and 22 years (M = 18.6, SD = 1.39). The purpose of this cross-sectional study was to examine whether stress mediated the relationship between body dissatisfaction and eating disorders. The study included the administration of stress and self-efficacy and the locus of control dimensions, body (image) dissatisfaction, and eating attitude disorder. Results indicated higher scores on body dissatisfaction, stress level, and eating attitudes disorder among the group of fashion models compared to the control. Mediational analyses showed that body dissatisfaction was partially mediated by stress level on eating disorders. Especially in the aspiring fashion models, there are often many possibilities that competitive stress causes candidates to exacerbate attempts to maintain their body weight below normal weight/height parameters. These results indicated that appropriate intervention for the management of stress level could possibly defend against the negative impact of body dissatisfaction on eating disorder symptoms. The presence of skilled health workers in the field of nutrition and psychology can be extremely important in the field of fashion to maintain an adequate quality of life.

The Relationship between Emotional Intelligence, Obesity and Eating Disorder in Children and Adolescents: A Systematic Mapping Review

Eating and weight disorders often develop early in life and cause a long-standing significant health burden. Given the documented role of emotional intelligence (EI) in shaping the body image and predicting the onset of eating disorders, knowledge of the mechanisms involved in EI among youth is fundamental to designing specific interventions for screening and prevention of obesity and eating disorders (EDs). The present systematic mapping review was aimed to explore and quantify the nature and distribution of existing research investigating the impact of EI on EDs in young people. A systematic search for relevant articles was conducted using PubMed, Scopus, PsycINFO and Web of Science databases. The Appraisal tool for Cross-Sectional Studies (AXIS) was used to assess the included studies’ methodological quality. The included studies’ results were mapped based on stratification by age groups (children, preadolescents, and adolescents), population (clinical vs. non-clinical) and disordered eating outcomes. Nine studies were included, supporting the association between EI and body image dissatisfaction, ED risk and bulimic symptomatology, but not with anorexic symptoms. Research on children and clinical populations was scant. Further studies are needed to deepen the role of EI in the genesis and maintenance of EDs.
