Development and predictive effects of eating disorder risk factors during adolescence: Implications for prevention efforts

Preliminary Effectiveness of a Brief School-Based HERO Intervention: Improving the Wellbeing of Final Year Adolescent Female Students

Young people face multiple challenges, including appearance dissatisfaction, academic stressors, anxiety and depression. These challenges may increase during the final year of high school and may have become further exacerbated by the COVID-19 pandemic. This study examines the preliminary effectiveness of a brief, uncontrolled school-based intervention aimed at enhancing Psychological Capital (PsyCap), consisting of positive resources of hope, self-efficacy, resilience and optimism (HERO), and reducing mental health symptoms among female year 12 students (n = 95, Mage = 16.78, SD = 0.45). Outcomes on measures of HERO and secondary outcomes of flourishing, appearance dissatisfaction, anxiety and depression were measured at pre and post-intervention. In the overall cohort, no significant changes were found on the HERO outcomes or flourishing post-intervention, while symptoms of depression, anxiety and appearance dissatisfaction decreased significantly. For students with higher baseline anxiety, optimism and anxiety symptoms improved significantly at post-intervention. However, students with lower baseline anxiety experienced significant decreases in self-efficacy and optimism, as well as a significant increase in anxiety symptoms post-intervention. Baseline depression levels did not impact intervention outcomes. The findings, although mixed and limited by the lack of control group, suggest that a brief intervention grounded in PsyCap theory may improve student wellbeing under challenging circumstances.

Association of body mass index with progression from binge-eating behavior into binge-eating disorder among adolescents in the United States: a prospective analysis of pooled data

The association between body mass index (BMI) and binge-eating disorder (BED) is well-established. However, data on the extent to which BMI is associated with progression from binge-eating behavior into BED among adolescents are limited, which was the aim of this investigation. Participants were 9,964 U.S. adolescents from the Adolescent Brain Cognitive Development (ABCD) Study, aged 9-13 at the time of study enrollment. A computerized parent-reported assessment was used to establish adolescents' binge-eating behaviors and BED. Cox proportional hazards models adjusting for sociodemographic covariates were used to examine prospective associations between BMI and likelihood of BED onset among a) adolescents with binge-eating behavior, and b) adolescents with no binge-eating behavior. Of 975 adolescents who met study criteria for binge-eating behavior, 89 (9.1%) subsequently met study criteria for BED. Of 8,989 adolescents with no binge-eating behavior, 82 (0.9%) subsequently met study criteria for BED. BMI percentile was significantly associated with the likelihood of BED onset in participants with [ adjusted HR =1.03 (1.00, 1.06)] and participants without [adjusted HR =1.05 (1.03, 1.07)] binge-eating behavior. Results were also significant when examining BMI as a dichotomous predictor (above and below 85th percentile) among those with [adjusted HR =2.60 (1.00, 6.68) and those without [adjusted HR =6.01 (3.90, 11.10)] binge-eating behavior. Overall, results indicate that elevated BMI is prospectively associated with a greater risk for BED onset among U.S. adolescents with or without binge-eating behavior. Adolescents with a higher BMI may benefit from screening for binge eating, and prevention/early intervention strategies to mitigate the risk for developing BED.

Early childhood appetitive traits and eating disorder symptoms in adolescence: a 10-year longitudinal follow-up study in the Netherlands and the UK

BACKGROUND

Obesity and eating disorders commonly co-occur and might share common risk factors. Appetite avidity is an established neurobehavioural risk factor for obesity from early life, but the role of appetite in eating disorder susceptibility is unclear. We aimed to examine longitudinal associations between appetitive traits in early childhood and eating disorder symptoms in adolescence.

METHODS

In this longitudinal cohort study, we used data from Generation R (based in Rotterdam, the Netherlands) and Gemini (based in England and Wales). Appetitive traits at age 4-5 years were measured using the parent-reported Child Eating Behaviour Questionnaire. At age 12-14 years, adolescents self-reported on overeating eating disorder symptoms (binge eating symptoms, uncontrolled eating, and emotional eating) and restrictive eating disorder symptoms (compensatory behaviours and restrained eating). Missing data on covariates were imputed using Multivariate Imputation via Chained Equations. Ordinal and binary logistic regressions were performed in each cohort separately and adjusted for confounders. Pooled results were obtained by meta-analyses. Sensitivity analyses were performed on complete cases using inverse probability weighting.

FINDINGS

The final study sample included 2801 participants from Generation R and 869 participants from Gemini. Pooled findings after meta-analyses showed that higher food responsiveness in early childhood increased the odds of binge eating symptoms (odds ratio [OR]pooled 1·47, 95% CI 1·26-1·72), uncontrolled eating (1·33, 1·21-1·46), emotional eating (1·26, 1·13-1·41), restrained eating (1·16, 1·06-1·27), and compensatory behaviours (1·18, 1·08-1·30) in adolescence. Greater emotional overeating in early childhood increased the odds of compensatory behaviours (1·18, 1·06-1·33). By contrast, greater satiety responsiveness in early childhood decreased the odds of compensatory behaviours in adolescence (0·89, 0·81-0·99) and uncontrolled eating (0·86, 0·78-0·95) in adolescence. Slower eating in early childhood decreased the odds of compensatory behaviours (0·91, 0·84-0·99) and restrained eating (0·90, 0·83-0·98) in adolescence. No other associations were observed.

INTERPRETATION

In this study, higher food responsiveness in early childhood was associated with a higher likelihood of self-reported eating disorder symptoms in adolescence, whereas greater satiety sensitivity and slower eating were associated with a lower likelihood of some eating disorder symptoms. Appetitive traits in children might be early neurobehavioural risk factors for, or markers of, subsequent eating disorder symptoms.

A pilot study of a virtually delivered dissonance-based eating disorder prevention program for young women with type 1 diabetes: within-subject changes over 6-month follow-up

INTRODUCTION

In an uncontrolled study, we previously demonstrated the feasibility and preliminary efficacy of our virtual diabetes-specific version (Diabetes Body Project) of the eating disorder (ED) prevention program the Body Project. The aim of the current study was to evaluate further this program for women with type 1 diabetes (T1D) by assessing within-subject changes in outcomes from pretest over 6-month follow-up.

METHODS

Young women with T1D aged 16-35 years were invited to participate in Diabetes Body Project groups. A total of 35 participants were allocated to five Diabetes Body Project groups (six meetings over 6 weeks). Primary outcome measures included ED risk factors and symptoms, and secondary outcomes included three T1D-specific constructs previously found to be associated with ED pathology: glycemic control as measured by HbA1c level, diabetes distress, and illness perceptions.

RESULTS

Within-subject reductions, with medium-to-large effect sizes, were observed for the primary (ED pathology, body dissatisfaction, thin-ideal internalization, and appearance ideals and pressures) and secondary outcomes (within-condition Cohen's ds ranged from .34 to 1.70).

CONCLUSION

The virtual Diabetes Body Project appears to be a promising intervention worthy of more rigorous evaluation. A randomized controlled trial with at least a 1-year follow-up is warranted to determine its efficacy compared to a control condition.

Gait pattern can alter aesthetic visual impression from a third-person perspective

Beauty is related to our lives in various ways and examining it from an interdisciplinary approach is essential. People are very concerned with their appearance. A widely accepted beauty ideal is that the thinner an individual is, the more beautiful they are. However, the effect of continuous motion on body form aesthetics is unclear. Additionally, an upright pelvic posture in the sagittal plane during walking seems to affect the aesthetic judgments of female appearance. We directly analyzed the influence of body form and walking pattern on aesthetic visual impressions from a third-person perspective with a two-way analysis of variance. Captured motion data for three conditions-upright pelvis, normal pelvis, and posteriorly tilted pelvic posture-were applied to each of three mannequins, representing thin, standard, and obese body forms. When participants watched stimulus videos of the mannequins walking with various postures, a significantly higher score for aesthetic visual impression was noted for an upright pelvic posture than for a posteriorly tilted pelvic posture, irrespective of body form (F(2, 119) = 79.89, p < 0.001, η2 = 0.54). These findings show that the third-person perspective of beauty can be improved even without being thin by walking with an upright pelvic posture.

Longitudinal associations between response-style strategies and abnormal eating behaviors/attitudes in adolescents: a cross-lagged panel model

BACKGROUND

Previous studies have suggested that response-style strategies (rumination, problem-solving, and distraction) can be risk or protective factors for the development of abnormal eating behaviors/attitudes (AEB) during adolescence. However, due to limited empirical data regarding the prospective effects of these strategies on AEB, further research is needed to clarify their role in developing AEB in adolescence.

METHODS

This study investigated the one-year lagged effects of response-style strategies on AEB in 24,883 fourth- to eighth-grade students in Japan between 2015 and 2019 using a cross-lagged panel model. Depressive symptoms and body mass index (BMI), which are reported to relate to AEB, were also included in the analytic model. The students self-reported their levels of response-style strategies, AEB, and depressive symptoms. We also evaluated BMI based on teachers' reports.

RESULTS

We found that greater rumination significantly predicted more severe AEB in the following year among students from all grades, with small to moderate effect sizes. In addition, distraction significantly predicted more severe binge eating/purging behaviors, but with very weak small effect sizes. Problem-solving did not predict any level of AEB. Furthermore, we observed significant reciprocal relationships between response-style strategies, AEB, and depressive symptoms. Positive reciprocal associations between BMI and AEB were also found except for some intervals.

CONCLUSIONS

We concluded that a decrease in rumination is critical to alleviating mental health problems, such as AEB and depressive symptoms, during adolescence. This suggests that interventions to reduce the level of rumination should be conducted in the early stages of adolescence.

Psychological correlates of body dissatisfaction in Swiss youth over a one-year study-period

Introduction

It is well known that young individuals often report pronounced negative perceptions and attitudes towards their own body or intense fear of being not muscular enough. There is much less data available, however, on the role of psychological mechanisms on these perceptions and attitudes, such as emotion regulation difficulties, correlates of alexithymia, and appearance-related rejection sensitivity.

Methods

We therefore set out to assess associations between these psychological mechanisms, and body image as well as muscle dysmorphic symptoms. Our sample was recruited as part of a larger-scale study aiming at assessing correlates of mental health (with a focus on eating disorder symptoms) in German speaking Switzerland. The first wave (T1), starting in April 2021, included 605 participants (80% female, 19.6 ± 2.5 years) who completed the online-questionnaire and were reassessed in a second wave (T2), one year later.

Results

Results indicated that at both waves, emotion regulation difficulties [DERS-SF] and appearance-based rejection sensitivity [ARS-D] were both positively cross-sectionally associated with body dissatisfaction [BSQ-8C] and muscle dysmorphic symptoms [MDDI] at the first assessment time-point and one year later at follow-up assessment. Moreover, alexithymia [TAS-20] was positively cross-sectionally associated with muscle dysmorphic symptoms at both waves. We further observed high absolute and relative level stabilities for all variables involved across the one-year study period.

Discussion/Conclusion

Even though the effects for some associations were rather small, our findings underline the relevance of such mechanisms in the development of body dissatisfaction and to a lesser extent of muscle dysmorphia symptoms over the period of one year. Additional research is necessary to replicate these findings in other youth samples.

The role of developmental caregiving programming in modulating our affiliation tendency and the vulnerability to social anxiety and eating disorders

Attachment is the evolutionarily-established process through which humans create bonds with others to receive care from them. The phenomenon is as essential to our physical survival as it is to our psychological development. An increasing number of studies demonstrates that in sensitive periods during the early years of life, our brain circuitry is programmed in the interactions with our caregivers, with the imprinting of information over multiple attachment dimensions. Adopting a basic brain-computer analogy, we can think of this knowledge as the psycho-social firmware of our mind. According to a recently proposed extension of the classical three-dimensional view, one attachment dimension - somaticity - concerns the caregiver's task of reflecting and confirming the child's (internal) states - such as sensations, emotions, and representations - to support the child's ability to identify and define those entities autonomously. Relying on multidisciplinary evidence - from neuroscientific, developmental, evolutionary, and clinical sources - we suggest that somaticity (H1) has the adaptive function to modulate our tendency to comply and affiliate with a reference group but also (H2) increases the vulnerability to developing Social Anxiety (SA) and Eating Disorders (EDs). We evaluate H1-H2, (1) indicating the evolutionary role of somaticity in modulating our affiliation tendency to optimize the ancestral threat-opportunity balance coming from infectious diseases and (2) showing the deep connection between SA-EDs and the features most closely related to somaticity - interoception and parenting style. Finally, we discuss three relevant implications of H1-H2: (A) Bringing into research focus the adaptive role of our firmware knowledge system versus the hardware (neural substrate) and software (higher cognition) ones. (B) Complementing the well-grounded Objectification and Allocentric Lock Theories, allowing us to integrate multiple levels of explanation on the etiology of psychopathology. (C) Suggesting the design of new psychological treatments. While not aiming to prove H1-H2, our analysis supports them and encourages their direct testing.

Evidence-Based Assessments for Transdiagnostic Eating Disorder Symptoms: Guidelines for Current Use and Future Directions

Eating disorders are severe and often chronic mental illnesses that are associated with high impairment and mortality rates. Recent estimates suggest that eating disorder prevalence rates are on the rise, indicating an increased need for accurate assessment and detection. The current review provides an overview of transdiagnostic eating disorder assessments, including interview, self-report, health and primary care screeners, and technology-based and objective assessments. We focused on assessments that are transdiagnostic in nature and exhibit high impact in the field. We provide recommendations for how these assessments should be used in research and clinical settings. We also discuss considerations that are crucial for assessment, including the use of a categorical versus dimensional diagnostic framework, assessment of eating disorders in related fields (i.e., anxiety and depression), and measurement-based care for eating disorders. Finally, we provide suggestions for future research, including the need for more research on short transdiagnostic screeners for use in health care settings, standardized assessments for ecological momentary assessment, development of state-based assessment of eating disorder symptoms, and consideration of assessment across multiple timescales.

Sex Differences in Diet and Physical Activity Behaviors Among Racial/Ethnic Minority Adolescents with High Metabolic Risk

Certain dietary and physical activity (PA) behaviors may differentially predispose male and female adolescents to obesity and diabetes; however, sex differences in dietary and PA behaviors and in factors that impact these behaviors (e.g., self-efficacy, social support) in this population remain unknown. Using data from a community-based adolescent diabetes prevention intervention conducted in East Harlem in New York City, we examined sex differences in baseline characteristics including clinical measurements, lifestyle behaviors, and behavioral determinants. Among 147 overweight/obese adolescents aged 13-19 years, 61.9% were girls, 69.7% were of Hispanic ethnicity, 24.8% were non-Hispanic Black, and 60.5% were diagnosed with prediabetes. Boys had higher metabolic risk scores than girls (3.8 vs. 3.3, p = 0.002) despite girls reporting more perceived barriers to healthy eating and PA. Boys reported doing more moderate to vigorous PA but also had more sedentary behaviors than girls. Boys reported higher self-efficacy and more peer support for PA. Girls reported more depressive symptoms and were more likely to compare their body images to those in magazines/social media. Overall, among a sample of urban adolescents with high metabolic risk, we found significant sex differences in many dietary and PA behaviors and related factors, which could be used to inform tailored strategies for weight management to reduce cardiometabolic risk among youth from similar high-risk populations.

COVID-19-related anxiety and trauma symptoms predict decreases in body image satisfaction in children

The present study investigated short-term longitudinal effects of COVID-19-related trauma and separation, social, and generalized anxiety symptoms on children's body image satisfaction. Participants were 247 Canadian children (121 boys, 123 girls) aged between 7 and 12 years (M = 9.04). Two cohorts of parents were recruited to complete a questionnaire at two time points on their children's body image satisfaction and COVID-19-related trauma and anxiety symptoms. The first cohort (n = 136 children) was recruited in Summer 2020 and the second cohort (n = 111 children) was recruited in Winter 2021. For each cohort, follow-up surveys were completed approximately five months later, therefore covering an entire year with both cohorts. Multilevel regression analyses showed that children's trauma and anxiety at Time 1 predicted significant decreases in body image satisfaction at Time 2. Older children were especially at risk of decreased body image satisfaction as a result of their COVID-19-related trauma, social anxiety and generalized anxiety symptoms. Younger girls were susceptible to decreased body image satisfaction as a result of their separation anxiety symptoms. Given that children's body image dissatisfaction is a precursor to the development of eating disorders, these findings shed light on potential targets for early intervention with children who are at-risk of developing such difficulties.

Unveiling Skin Manifestations: Exploring Cutaneous Signs of Malnutrition in Eating Disorders

The intricate interplay between eating disorders, malnutrition, and their cutaneous manifestations is the focal point of this comprehensive review. The review delves into the clinical significance of recognising and understanding these visible signs in the context of eating disorders. It highlights the vital role of nutrition in maintaining healthy skin and addresses the challenges associated with relying solely on cutaneous signs for diagnosis. Emphasising a multidisciplinary approach involving dermatologists, psychiatrists, and nutritionists, the review underscores the holistic nature of the treatment. Addressing psychological aspects alongside nutritional rehabilitation is underscored with a forward-looking perspective on future research avenues. This review is valuable for healthcare professionals by synthesising existing knowledge and identifying research gaps. It aims to improve the diagnosis, treatment, and preventative strategies for individuals dealing with the complex challenges of eating disorders and malnutrition.

Risk factors of disordered eating in adolescent girls from a community sample: a multidimensional approach

BACKGROUND

Eating disorders (ED) are severe, chronic, and complex in nature mental illnesses that are difficult to treat. One of the ways to stave off EDs is by screening among adolescents to preempt the development of clinical forms of ED in risk groups.

AIM

1) to investigate the prevalence of ED risk among adolescent girls and compare subgroups at high and low risk of ED; 2) to investigate using a multidimensional approach those variables that can interact with temperament and character traits to predict ED symptomatology.

METHODS

The cross-sectional observational self-report study of a community sample of adolescent girls 1217 years old (n=298; M=14.771.13) was carried out in the city of Ryazan, Russia. The Russian versions of Eating Attitudes Test and Cloningers Temperament and Character Inventory-Revised were used. In addition, an original questionnaire (Risk Factors of Eating Disorders) was developed. Regression models (to test for significant moderation) and path analysis (to test for significant mediations) were used.

RESULTS

Girls at risk of developing EDs are characterized by a heightened level of concern about weight and dissatisfaction with their body, tend to suffer from low self-directedness, higher novelty seeking and tendency to higher harm avoidance, display high alexithymia, experience self-distrust, negative emotionality and are dissatisfied with family relationships. They also suffer from low self-esteem and tend to be perfectionism and engage in risk behavior. Significant moderating effects were uncovered between the following ED risk factors: (1) self-distrust/risk behavior and BMI; (2) alexithymia/negative emotionality/self-esteem and cooperativeness; and (3) negative emotionality/risk behavior and self-transcendence. Family relationship dissatisfaction mediates the association between self-directedness/cooperativeness/self-transcendence and disordered eating.

CONCLUSION

There are various mutual influences between the numerous ED risk and prevention factors, which all together determine the paths between the predictors and final outcome.

Is a dissonance-based group intervention targeting thin-ideal internalization a successful potential add-on for specialized eating disorder care? A randomized feasibility and acceptability pilot study

BACKGROUND

Dissonance-based eating disorder programs have successfully targeted body dissatisfaction by challenging the thin beauty ideal in the preventive context and in groups of patients with a subthreshold and full threshold DSM-5 eating disorder. As there is a need for interventions specifically targeting thin-ideal internalization in (highly) specialized treatment centres, the present study adapted Stice's et al.'s Body Project for its use as an add-on treatment for severe eating disorders with the aims to identify whether it was feasible and acceptable in this treatment context, to determine any necessary modifications with regard to the treatment and study procedures, and to test preliminary effectiveness.

METHODS

The study was a randomized controlled pilot/feasibility trial. Thirty patients started in the Body Project group and 25 in the Psycho-education group. Measurements took place pre- and post-intervention, and at three and six months follow-up. Patients and staff evaluated treatment and study procedures, and patients completed questionnaires on thin-ideal internalization, body dissatisfaction, self-objectification, negative affect and eating disorder pathology.

RESULTS

The Body Project group and Psycho-education group both proved highly feasible and acceptable, as well as preliminarily effective, based on quantitative scores and qualitative feedback. Preliminary analyses showed that treatment effects did not differ between treatment groups. As both groups were an add-on to standard treatment, treatment effects cannot be disentangled from effects resulting from standard treatment. Qualitative feedback for the Body Project group included several recommendations for future implementation: increasing the number of treatment sessions, creating homogeneous therapy groups, and optimizing timing of the treatment.

CONCLUSIONS

Future research should examine further modifications to the Body Project group for severe eating disorders, as well as for whom, and when in the course of treatment the intervention is most effective. The present study also showed the benefits of implementing a structured Psycho-education group. We tested the feasibility and acceptability of a group intervention targeting the thin beauty ideal (Body Project group) in patients with severe eating disorders and compared this intervention to a group intervention focusing on psycho-education about eating disorders (Psycho-education group). Both interventions were added to standard treatment. We adapted the protocol for patients with severe eating disorders. Both the Body Project group and the Psycho-education group were evaluated by patients as well as staff as highly feasible and acceptable, and effects were positive. Treatment effects did not differ between treatment groups. As both treatments were an add-on to standard treatment, treatment effects cannot be disentangled from effects resulting from standard treatment. The study suggested further modifications to the Body Project group. Future research should examine these modifications as well as for whom, and when in the course of treatment the intervention is most effective. The present study also showed the benefits of implementing a structured Psycho-education group.

Evidence that a novel transdiagnostic eating disorder treatment reduces reward region response to the thin beauty ideal and high-calorie binge foods

BACKGROUND

Findings from brain imaging studies with small samples can show limited reproducibility. Thus, we tested whether the evidence that a transdiagnostic eating disorder treatment reduces responsivity of brain valuation regions to thin models and high-calorie binge foods, the intervention targets, from a smaller earlier trial emerged when we recruited additional participants.

METHODS

Women with DSM-5 eating disorders (N = 138) were randomized to the dissonance-based body project treatment (BPT) or a waitlist control condition and completed functional magnetic resonance imaging (fMRI) scans assessing neural response to thin models and high-calorie foods at pretest and posttest.

RESULTS

BPT v. control participants showed significantly greater reductions in responsivity of regions implicated in reward valuation (caudate) and attentional motivation (precuneus) to thin v. average-weight models, echoing findings from the smaller sample. Data from this larger sample also provided novel evidence that BPT v. control participants showed greater reductions in responsivity of regions implicated in reward valuation (ventrolateral prefrontal cortex) and food craving (hippocampus) to high-calorie binge foods v. low-calorie foods, as well as significantly greater reductions in eating disorder symptoms, abstinence from binge eating and purging behaviors, palatability ratings for high calorie foods, monetary value for high-calorie binge foods, and significantly greater increases in attractiveness ratings of average weight models.

CONCLUSIONS

Results from this larger sample provide evidence that BPT reduces valuation of the thin ideal and high-calorie binge foods, the intervention targets, per objective brain imaging data, and produces clinically meaningful reductions in eating pathology.

Food insecurity and disordered eating behaviors in children and adolescents: A systematic review

This study is the first systematic review to investigate the relationship between food insecurity (FI) and disordered eating behaviors exclusively in children and adolescents. Database searches were conducted in PUBMED, Embase, PsycINFO, ProQuest, and Gale OneFile: Informe Académico using English and Spanish search terms. Studies were included if they were published before August 2022, included youth aged 18 years and below, included either parent- or child-report of food security status, included either parent- or child-report of child disordered eating behaviors, and examined the relationship between food security status and child disordered eating behaviors. Following independent title/abstract and full-text screening, 20 studies were included in the review. There were 13 cross-sectional studies, five longitudinal studies, and two qualitative studies, from the United States (19 studies), and Bangladesh (1 study). Sample sizes ranged from 33 to 6077. Findings generally indicated a relationship between FI and behaviors such as binge eating, loss-of-control eating, eating in the absence of hunger, unhealthy weight control behaviors, and picky eating in children and adolescents, though this association varied depending on the type of disordered eating behavior assessed and FI severity. Results highlight the importance of screening for disordered eating behaviors among youth with FI towards eating disorder prevention and intervention. However, given the limited number of primary research articles examining this relationship in youth, further hypothesis-driven research is needed. In addition, more global representation and additional longitudinal studies are needed to further examine the generalizability and temporality of FI and disordered eating in children and adolescents.

The role of mothers' involvement in their daughters' self-esteem and dieting behaviors

This study presents an initial effort to develop disordered eating pathology (DEP) prevention program with an emphasis on maternal involvement. Disordered eating pathology representing a range of behaviors and attitudes, from negative body image to full-blown eating disorder. It appears mainly in adolescent females and related to psychological and familial factors, including maternal modeling of thinness. A sample of 118 Israeli girls (11-12) was divided into three groups: participants in the program in parallel with their mothers, participants without their mothers, and control. Participants completed self-report questionnaires. Groups were tested three times: pre-intervention, post-intervention, and follow-up. For those girls who participated in parallel with their mothers, higher self-esteem was associated with fewer pathological diet behaviors. Findings deepen understanding of the risk factors involved in the development of DEP. The main study contribution is the important role mothers play in preventing DEP among their daughters.

Prevention and early intervention in eating disorders: findings from a rapid review

BACKGROUND

Eating disorders (EDs) are complex psychological disorders, with low rates of detection and early intervention. They can lead to significant mental and physical health complications, especially if intervention is delayed. Given high rates of morbidity and mortality, low treatment uptake, and significant rates of relapse, it is important to examine prevention, early intervention, and early recognition initiatives. The aim of this review is to identify and evaluate literature on preventative and early intervention programs in EDs.

METHODS

This paper is one of a series of Rapid Reviews, designed to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded, and released by the Australian Government. To provide a current and rigorous review, peer-reviewed articles between 2009 and 2021 published in English were searched across three databases: ScienceDirect, PubMed and Ovid/Medline. Priority was given to high-level evidence including meta-analyses, systematic reviews, Randomised Control Trials, and large population studies. Findings from selected studies pertaining to prevention and early intervention in EDs were evaluated and are presented in this review.

RESULTS

In total, 130 studies were identified in the current review, 72% relating to prevention and 28% to early intervention. Most programs were theory-driven and targeted one or more ED risk factors such as thin-ideal internalisation and/or body dissatisfaction. There is reasonable evidence to support prevention programs reducing risk factors, particularly as part of school or university-based programs, with established feasibility and relatively high acceptance among students. There is increasing evidence around the use of technology (to increase dissemination potential) and for use of mindfulness approaches (targeting emotional resilience). Few longitudinal studies assessing incident cases following participation in a prevention program exist.

CONCLUSIONS

Although several prevention and early intervention programs have been shown to significantly reduce risk factors, promote symptom recognition, and encourage help-seeking behaviour, most of these studies have been conducted in older adolescent and university aged students, past the age of peak ED onset. One of the most targeted risk factors, body dissatisfaction, is found in girls as young as 6 years old, indicating a need for further research implementing prevention initiatives at younger ages. Follow-up research is limited; thus, the long-term efficacy and effectiveness of studied programs is unknown. Greater attention should be paid to the implementation of prevention and early intervention programs in identified high-risk cohorts or diverse groups, where a more targeted approach may be necessary.

Social comparisons on social media: online appearance-related activity and body dissatisfaction in adolescent girls

INTRODUCTION

Adolescents' engagement with online social networking platforms is advancing at an exponential rate and research is needed to investigate any impact on young users' mental health. This study examined appearance-related activity (e.g. looking at photos of friends) on social media and body dissatisfaction among adolescent girls.

METHODS

Self-report measures of online appearance-related activity, social comparisons to female target groups, internalization of the thin ideal, body dissatisfaction, and self-esteem were administered to 210 girls (mean age = 15.16 years).

RESULTS

Body dissatisfaction was significantly related to (i) time spent engaged in social comparisons and (ii) upward social comparisons with various female targets while online. Evaluating oneself less favorably than the target group of close friends was most strongly associated with poorer body image appraisals. Serial multiple mediation analysis revealed that even after controlling for age and self-esteem, time spent engaged in social comparisons significantly mediated the relationship between online appearance-related activity and body dissatisfaction. This association was then further partially mediated by internalization of the thin ideal, which significantly mediated the relationship between time engaged in social comparisons and body dissatisfaction.

DISCUSSION

Results are discussed in terms of online social media platforms representing an additional appearance culture environment for adolescent girls. The effects of this on the mental health of vulnerable users and how future research should investigate protective factors that may buffer young girls from the adverse effects of social media are considered.

Emotional intelligence subdimensions as moderators in the association between body dissatisfaction and symptoms of eating disorders among female Mexican adolescents

OBJECTIVE

Strong empirical research has shown a relationship between body dissatisfaction and symptoms of eating disorders (ED) and the direct and combined influence of emotional factors and dimensions of emotional intelligence (EI) on ED symptoms. However, whether these emotional variables and competencies moderate the well-established relationship between body dissatisfaction and ED symptomatology has not yet been tested. Neither have studies of this nature been performed among high at-risk populations such as Mexican female adolescents. Thus, this research aimed to explore the moderator role of EI subdimensions in the relationship between body dissatisfaction and ED symptoms among female adolescents from Sinaloa, Mexico.

METHODS

A total of 485 female adolescents aged 14-19 years old (M = 16.81, SD = 1.33) who were students in middle school, high school, and college completed questionnaires about body dissatisfaction, ED symptomatology, and EI. We conducted moderating analyses.

RESULTS

Subdimensions of EI significantly moderated the relationship between body dissatisfaction and symptoms of ED. For participants high in body dissatisfaction, lower levels in stress management ability and higher levels in the interpersonal EI and Adaptability EI dimensions were associated with higher levels of ED symptomatology.

DISCUSSION

Subdimensions of EI have an important role in moderating the association between body dissatisfaction and symptoms of ED. The findings of this study contribute to improving the knowledge about the role of emotional competencies in ED. Proposals for future research and to improve preventative approaches are discussed.

PUBLIC SIGNIFICANCE STATEMENT

This study shows the moderating role of EI dimensions in the well-established relationship between body dissatisfaction and ED symptomatology. The research was conducted with a population at high risk of ED: female adolescents in the northwest of Mexico. Results showed that low Stress management EI, high Adaptability EI, and high Interpersonal EI were associated with higher levels of ED symptomatology among participants with high (but not low) body dissatisfaction. These insightful results have theoretical and practical implications.

Cross-cultural adaptation of the Eating Beliefs Questionnaire into Brazilian Portuguese

OBJECTIVE

The aim of this study was the cross-cultural adaptation of the Eating Belief Questionnaire (EBQ)-an instrument that assesses positive, negative, and permissive eating beliefs in relation to binge eating episodes-in its shorted version of 18 questions, into Brazilian Portuguese, for female teenagers.

METHODS

Conceptual, semantic, cultural and operational equivalence of the items were evaluated. The semantic and cultural equivalence involved 12 bilingual people and 12 experts in eating behavior. Operational equivalence consisted of applying the transcultural adapted version of the EBQ-18 to 20 girls with a mean age of 17.55 (SD=1.00) years. Item's clarity and understanding were assessed by the Content Validity Coefficient.

RESULTS

Questions 5, 6, 11, 14, 15, 16, 17 and 18, with adequate classification percentage for all equivalences, were not altered. The other items were adapted according to the committee's suggestions and by consensus among researchers. The adapted version of the EBQ-18 in Brazilian Portuguese displayed good content validity coefficient for clarity (CVC=0.975) and comprehension (CVC=0.971); except for item 3, all items had values between 0.88 and 1.00.

CONCLUSION

The Brazilian Portuguese version of the EBQ-18 had a good understanding by the adolescent public when it comes to investigate the role of dietary beliefs in the maintenance of binge eating episodes. Future studies with adolescents are recommended, jointly assessing risk for and presence of eating disorders in significant clinical and non-clinical samples, as well as its psychometrics properties.

A Qualitative Exploration of Body Image from the Perspective of Adolescents with a Focus on Psychological Aspects: Findings from Iran

The current study employs a qualitative approach to uncover the perceptions of Iranian adolescents regarding their bodies, with a focus on the psychological components that contribute to their body image perceptions. Data collection conducted using 13 semi-structured focus group discussions with 42 girls and 42 boys (15-18 years). All focus group discussions were audio recorded and transcribed verbatim. Data analysis was done manually using constant comparative analysis according to the Strauss and Corbin analysis method. Based on the participants' statements, four main themes and related categories emerged from data: (1) Beliefs including uncontrollable body, biased opinion of those around, priority of health, spiritual/religious beliefs and affecting future success, (2) Body-evaluation including direct body evaluation and indirect body evaluation, (3) Feelings and emotions including disgust and hatred, frustration, sadness, shame, envy, fear, approval and satisfaction and (4) Behaviors including lifestyle modifications, beautifying and using make up, extreme dieting, physical inactivity, avoidance behaviors, passive behaviors, aggressive behaviors and social isolation. Findings of the current study provide further information regarding cognitive, emotional and behavioral aspects of body image from the perspectives of adolescents in a West-Asian region.

Adaptação transcultural do Eating Beliefs Questionnaire para português do Brasil

RESUMO Objetivo: Conduzir adaptação transcultural, para o português brasileiro, da versão reduzida de 18 questões do Eating Belief Questionnaire (EBQ) ao público de meninas adolescentes. O instrumento avalia crenças positivas, negativas e permissivas do comer com relação a episódios de compulsão. Métodos: Realizou-se avaliação das equivalências conceitual, semântica, cultural e operacional dos itens. A equivalência semântica e cultural envolveu 12 bilíngues e 12 especialistas em comportamento alimentar. A equivalência operacional consistiu na aplicação da versão transcultural adaptada do EBQ-18 em 20 meninas, com média de idade de 17,55 anos (DP=1,00). O grau de clareza e compreensão das questões foi avaliado pelo coeficiente de validade de conteúdo. Resultados: Na avaliação semântica e cultural, 8 itens tiveram classificação adequada para todas as equivalências e não sofreram alterações; 10 itens foram alterados de forma mínima, conforme sugestões dos especialistas e mediante consenso entre pesquisadoras; e apenas o item 3 sofreu adaptação após resultados da equivalência operacional. O modelo adaptado para o português apresentou bom coeficiente de validade de conteúdo para clareza (CVC=0,975) e compreensão (CVC=0,971); com exceção do item 3, todos os itens foram avaliados com valores entre 0,88 e 1,00. Conclusão: A versão em português do EBQ-18 apresentou-se com boa compreensão do público adolescente para investigação do papel de crenças alimentares na manutenção de episódios de compulsão. Recomendam-se trabalhos futuros avaliando conjuntamente risco e presença de transtornos alimentares em amostras significativas clínicas e não clínicas, bem como suas propriedades psicométricas.

The Reliability and Validation of the Children's Eating Attitude Test among Chinese Samples

The purpose of this study was to examine the psychometric properties of the Children's Eating Attitude Test (ChEAT) in a Chinese sample. A total of 906 children (mean age = 10.55, SD = 1.08) from three primary schools were evaluated by the ChEAT. Factor analysis was performed to examine the factor structure of the ChEAT. The children's body mass index (BMI) was applied to assess the concurrent validity of the ChEAT. The ChEAT showed good internal consistency (Cronbach's α = 0.819) and split-half reliability (0.816) in Chinese children. Exploratory factor analysis suggested a four-factor structure, consistent with previous studies, which explained 41.16% of the total variance. Confirmatory factor analysis indicated good construct validity for the Chinese sample. The Chinese version of the ChEAT showed evidence for reliability and validity to evaluate the eating attitudes and behaviors for Chinese children. The mean score of each factor of the ChEAT differed significantly among different genders and BMI groups. Overweight girls had more eating disorder problems than normal-weight girls, and boys with lower BMI showed higher social eating pressure.

The Needs of School Professionals for Eating Disorder Prevention in Australian Schools: A Mixed-Methods Survey

(1) Background: School professionals such as teachers and counsellors are uniquely positioned to facilitate discussion around disordered eating and body image; however, little is known about the needs of school professionals with respect to eating disorder prevention. This study aimed to explore the needs and perceptions of Australian school professionals regarding eating disorder prevention. (2) Methods: School professionals were recruited to a mixed-methods online cross-sectional survey. The survey assessed demographics and perceived needs and attitudes to eating disorder prevention. (3) Results: Most participants (92%) were willing to participate in eating disorder prevention; however, only 61% reported good knowledge and 41% reported feeling confident in implementing eating disorder prevention. Those who had received training in eating disorders (24%) reported higher confidence (p = 0.02) and knowledge (p = 0.04). Only 66% of respondents reported that all teachers should be involved in eating disorder prevention while barriers including workload, knowledge, and resources were commonly highlighted. Fewer respondents working in primary school settings reported the need for prevention approaches (p = 0.046). (4) Conclusions: Despite a willingness to be involved in the prevention of eating disorders, there are inconsistencies in attitudes regarding the role of school professionals in eating disorder prevention. The findings of this study reinforce that understanding professional roles, school settings, and personal attitudes is critical in the development of more efficacious school professional training and prevention interventions.

Clinically significant body dissatisfaction: prevalence and association with depressive symptoms in adolescent boys and girls

Body dissatisfaction is distressing and a risk factor for adverse consequences including eating disorders. However, data pertaining to the prevalence of body dissatisfaction in adolescence, a key period for its emergence, are lacking. This is a substantial barrier to tailored assessment and early intervention. This study addresses this gap and provides the prevalence of body dissatisfaction and associations with depressive symptoms and body change strategies. Adolescent boys (n = 367; Mage = 12.8, SD = 0.7) and girls (n = 368; Mage = 12.7, SD = 0.7) completed measures of body dissatisfaction and depressive symptoms with established cut-off levels. They also completed measures of dietary restraint and strategies to increase muscle size. Of boys and girls, 37.9% and 20.7%, respectively experienced moderate, and 6.8% and 19.6% experienced clinically significant body dissatisfaction, with higher rates among girls than boys and among adolescents aged 13 and 14 than aged 12. More than one-quarter of boys (26.70%) and one-third of girls (33.15%) reported subthreshold depressive symptoms or possible, probable or major depressive episodes. Girls revealed a higher prevalence of possible-, probable-, or major depressive episode than boys. Relative to those with no or low body dissatisfaction, adolescents with clinically significant body dissatisfaction were 24 times more likely to also report possible-, probable-, or major depressive episodes. Among boys and girls, clinically significant body dissatisfaction was associated with higher levels of dietary restraint and engagement in strategies to increase muscle size. Greater attention to identification and early intervention for body dissatisfaction is needed, especially for girls.

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.

Emotion regulation, perfectionism, and eating disorder symptoms in adolescents: the mediating role of cognitive eating patterns

Poor emotion regulation, along with elevated perfectionism, is recognised as a risk factor for the development of eating disorder (ED) symptoms. Therefore, the aim of our study was to examine the relationship between emotion regulation difficulties and perfectionism with ED symptoms, while controlling for emotional eating, uncontrolled eating, and cognitive restraint as mediators. In total, 482 adolescents (246 girls and 236 boys; M = 15.00, SD = 0.31) participated in this study. Based on the participants' body height and weight measured by the medical team during their regular preventive health examinations, the body mass index (BMI) was calculated. Participants also answered the Difficulties in Emotion Regulation Scale, Multidimensional Perfectionism Scale, Three-Factor Eating Questionnaire, and Eating Disorder Examination Questionnaire. According to the results obtained, adolescent girls in our sample reported more difficulties in emotion regulation, more uncontrolled and emotional eating, and more ED symptoms. A significant direct effect was found for difficulties in emotion regulation and ED symptoms but not for perfectionism. In addition, only emotional eating and cognitive restraint (not uncontrolled eating) mediated the relationship between difficulties in emotion regulation and perfectionism and ED symptoms. The results suggest that difficulties in emotion regulation may be more important than perfectionism in explaining ED symptoms in a sample of healthy adolescents. When adolescents experience problems in emotion regulation in combination with emotional or uncontrolled eating, they might be at a higher risk of experiencing concerns about weight and a variety of other ED symptoms, and this should be considered when planning preventive interventions for adolescents.

Factorial Model of Obese Adolescents: The Role of Body Image Concerns and Selective Depersonalization-A Pilot Study

BACKGROUND

The relationship binding body weight to psychological well-being is unclear. The present study aims at identifying the contribution, and specificity, of some dimensions (i.e., eating-related symptoms, body image disorders, eating habits, personality traits, and emotional difficulties) characterizing the psychological profile of obese adolescents (749 participants, 325 females; 58.3% normal-weight, 29.9% overweight, and 11.7% obese; mean age = 16.05, SD = 0.82).

METHODS

By introducing the scores obtained by standardized self-report tools into a generalized linear model, a factorial reduction design was used to detect the best fitting discriminant functions and the principal components explaining the higher proportion of the variance.

RESULTS

We found two discriminant functions correctly classifying 87.1% of normal-weight, 57.2% of overweight, and 68.2% of obese adolescents. Furthermore, two independent factors, explaining 69.68% of the total variance, emerged.

CONCLUSIONS

The first factor, "Body Image Concerns", included the drive for thinness, body dissatisfaction, and interpersonal distrust. The second factor, "Selective Depersonalization", included a trend toward depersonalization and dissatisfaction with the torso. The neurophysiological implications of our findings will be discussed.

Social Influence on Fad Diet Use: A Systematic Literature Review

Background: A fad diet is a broad term used to describe dieting methods that recommend altering the intake of macronutrients to specific proportions or instruct people to intake or avoid particular foods, often with the goal of rapid weight loss. Previous literature reviews report social influence impacts general diet behaviour, but have yet to examine fad diets, specifically. Therefore, the purpose of this systematic review was to synthesize literature related to social influence on an individual's fad diet use and understand the sociocultural factors related to diet use. Methods: Using PRISMA guidelines, Medline, PsycInfo, Embase, CINAHL, and CENTRAL databases were searched to identify articles investigating the impact of social on fad diet use. Covidence was used to manage the review process and Garrard's Matrix Method was used to extract data from reviewed articles (n   =   13). Results: A majority of reviewed studies examined interpersonal influence (62%) and reported social influence impacting a variety of fad diet behaviours (92%). Interpersonal and media influence were highlighted as motivating factors for adopting unhealthy dieting methods (54%), and studies showed interpersonal support impacted adoption and maintenance of fad diet use (23%). Also, social norms were reported to influence unhealthy weight control behaviours (15%). Discussion: This review revealed social influence is associated with the adoption, adherence, and termination of fad diets. The prevalence of fad diets in society and the lack of research on this topic warrants further examination of factors related to fad diets use and the spread among interpersonal networks.

The Impact of Teasing and Bullying Victimization on Disordered Eating and Body Image Disturbance Among Adolescents: A Systematic Review

Adolescence is a developmental period in which disordered eating and negative body image are highly prevalent, yet their risk factors are insufficiently understood and targeted. Despite research implicating both teasing and bullying victimization in the development of eating disorders, these strands of research are yet to be integrated. This systematic review hence aimed to identify whether teasing and bullying victimization are associated with greater risk of eating disorders and body image disturbance for adolescents. Systematic searches of PsycINFO and PubMed databases identified 79 papers that included quantitative analyses of the relationship between weight-related or nonspecific teasing or bullying victimization and disordered eating or body image disturbance. Overall, studies indicated that adolescents who are teased or bullied are more likely to experience disordered eating and negative body image compared to nonvictimized adolescents. This was more consistently observed in cross-sectional studies than in longitudinal findings. We identify several methodological limitations of the literature, including the infrequent consideration of potential mediating and moderating variables. Finally, we outline future directions such as temporal sequencing of the complex interrelationships among teasing and bullying, disordered eating, and body image disturbance in adolescents.

Reciprocal relations between body dissatisfaction and excessive exercise in college women

OBJECTIVE

Body dissatisfaction elevates the risk for disordered eating behaviors. Excessive exercise is prevalent among college women and associated with harm. Risk theory posits a bidirectional relationship between risk factors for disordered eating behaviors and the behaviors themselves. This study investigated the longitudinal, reciprocal relationship between body dissatisfaction and excessive exercise.

PARTICIPANTS AND METHODS

College women (n = 302) assessed in August (baseline) and November (follow-up).

RESULTS

Baseline body dissatisfaction significantly predicted increases in excessive exercise endorsement at follow-up, controlling for baseline excessive exercise endorsement and body mass index (BMI). Baseline excessive exercise endorsement predicted increases in body dissatisfaction at follow-up, controlling for baseline body dissatisfaction and BMI.

CONCLUSIONS

Findings support the presence of a positive feedback loop between body dissatisfaction and excessive exercise; both predict increases in risk for the other, regardless of weight status. Future research should test whether this process is ongoing and predicts further distress.

Evaluation of Web-Based Health Information From the Perspective of Women With Eating Disorders: Thematic Analysis

Background

Users with experience of eating disorders use the internet as a source of information, whether for prorecovery activities (such as web-based treatment, looking for information, support, and sharing) or activities that promote eating disorder behavior as a desirable lifestyle choice (such as pro–eating disorder communities and reading and creating pro–eating disorder posts). Their assessment of web-based eating disorder–related information is crucial for understanding the context of the illness and for health professionals and their web-based interventions.

Objective

This study aimed to understand the criteria young women with the experience of eating disorders use in evaluating eating disorder–related web-based information and what eating disorder–related characteristics of these women are involved in their evaluation.

Methods

We analyzed 30 semistructured individual interviews with Czech women aged 16 to 28 years with past or present eating disorder experience using a qualitative approach. Thematic analysis was adopted as an analytical tool.

Results

The specifics of eating disorder phases (the disorder stage and the treatment process) emerged as important aspects in the process of information assessment. Other specific characteristics of respondents (eg, motivation, abilities, and resources) addressed how the respondents arrived at certain web-based information and how they evaluated it. In addition, the respondents described some content cues as features of information (eg, novelty and social information pooling). Another finding is that other users’ attitudes, experiences, activities, and personal features are involved in the information evaluation of these users and the information presented by them. Finally, the respondents evaluated the websites’ visual look and graphic components.

Conclusions

This study shows that web-based information evaluation reported by women with experience of eating disorders is a complex process. The assessment is influenced by current personal characteristics related to the illness (mainly the motivation for maintaining or curing the eating disorder) using cues associated with information content, other users, and website look. The study findings have important implications for health professionals, who should ask their clients questions about web-based communities and their needs to understand what information and sources they choose.

A Longitudinal and Comparative Content Analysis of Instagram Fitness Posts

Body dissatisfaction is among the most common mental health challenges experienced by women and has been identified as a risk factor for disordered eating. Research has found that exposure to social media images depicting thin, muscular bodies, often dubbed ‘fitspiration’, may contribute to body dissatisfaction. Image-centred social media platforms, such as Instagram, have rising popularity among adolescents and young adults. However, little is known about the content of images produced by different fitness-related sources, such as those from fitness brands compared with individual users, and how fitness content on social media is evolving over time. This study sought to determine whether Instagram content varied between female fitness influencers and brands and how this content changed between 2019 and 2021. A longitudinal content analysis was conducted on a sample of 400 Instagram images using a coding scheme developed specifically for this project. The scheme coded images for fit ideal body depiction, fitness focus, objectification, and sexualisation. Chi-square tests indicated that female fitness influencer content was more sexualised and portrayed more of the fit ideal, while fitness brands produced more Instagram content with a fitness focus. There were no significant overall longitudinal changes for any of the four key variables. However, when looking at longitudinal changes by account type, fitness-focused influencer content increased while fitness-focused brand content decreased over time. These findings highlight discernible differences in content produced by different Instagram account types. It points future research towards the consideration of potential moderating factors, such as account type, when exploring the impact of social media images on body image and mental health.

Advantages and Disadvantages of Internet Use: The Perspective of Women with Eating Disorders Experience

Even though the internet is a common source of information and treatment for people with eating disorder (ED) experience, the motives for illness-related searches have rarely been investigated beyond the perceived negatives. This study explores how women with ED experience reflect upon the advantages and disadvantages of their ED-related internet use. We expand the framework of the Uses and Gratifications Theory (U&G) into the context of users with ED experience through 30 semi-structured interviews with women with ED experience, aged 16 to 28, who live in the Czech Republic. Thematic analysis revealed four themes related to the pros and cons of their internet usage: ED-related Information Content; Internet Features Important to Users; Body Image; and Social Interaction. The results challenge the binary view of ED-related internet use and question some presumptions of U&G Theory within the specific context of users with ED experience.

Factors of body dissatisfaction among lebanese adolescents: the indirect effect of self-esteem between mental health and body dissatisfaction

Background

Body dissatisfaction (BD) rates are alarmingly high, especially among adolescents, thus. Having a better understanding of correlates associated with BD seems to be an important issue in this developmental context. Furthermore, as adolescence is an essential time in the development of self-perception and self-esteem the current study assesses factors associated with BD among Lebanese adolescents and evaluates the indirect effect of self-esteem between depression/anxiety/stress and BD.

Methods

This is a cross-sectional study among 555 Lebanese adolescents, ages 15–18, who completed an online survey incorporating BD, socioeconomic status, weight and height, physical activity index, Rosenberg Self Esteem Scale, Beirut Distress Scale, Hamilton Anxiety Rating Scale, Patient Health Questionnaire-9, Pittsburgh Sleep Quality Index and Global Physical Activity Questionnaire.

Results

The results of a stepwise linear regression, taking the body dissatisfaction score as the dependent variable, showed that higher BMI (B = 0.47), feeling pressured by media/TV to lose weight (Beta = 2.80), higher depression (Beta = 0.39), exercising to lose weight (Beta = 1.84) and following a diet to lose weight (Beta = 1.58) were significantly associated with more body dissatisfaction, whereas higher self-esteem (Beta=-0.11) and more psychological distress (Beta=-0.21) were significantly associated with less body dissatisfaction. Self-esteem played an indirect role in the associations between anxiety and body dissatisfaction and stress and body dissatisfaction.

Conclusions

BD is common among young Lebanese adolescents. Treating adolescents with low self-esteem and psychological issues is crucial in preventing anticipated BD and future eating disorders.

A Network Analysis Investigation of Disordered Eating Across Demographic and Developmental Subpopulations Using a National Epidemiological Sample of High School Students

Disordered eating (DE) poses a large societal burden, yet limited research has examined DE from a developmental epidemiological perspective. It is important to consider how demographics influence DE symptoms to inform prevention and early intervention programs across diverse subpopulations. Therefore, we conducted network analyses using a large nationally representative epidemiological sample of high school students (Youth Risk Behavior Survey, United States; n = 59,582) to identify the most important symptoms and symptom relationships among six DE behaviors. We compared networks by sex, grade, and race to identify differences in symptom networks. Dieting for weight loss was highly central across networks. Networks significantly differed across sex, grade, and race. Our results suggest that dieting for weight loss may be an early intervention target for eating disorders, regardless of demographic and developmental factors. In addition, sex, race, and age should be accounted for when researching and developing prevention programs for DE and eating disorders. Public health officials, as well as mental health professionals, should present a more balanced message about dieting and weight loss to high school students to prevent the detrimental impact of DE on physical and mental health. Notably, this study is the first large, nationwide epidemiological sample using DE symptoms in network analysis.

Physical activity motives have a direct effect on mental health

Physical activity (PA) motives are associated with both moderate-to-vigorous intensity PA (MVPA) and mental health. Studies examining whether PA motives relate directly to mental health or indirectly through MVPA are lacking. This study examined the direct effect of five PA motives (i.e., enjoyment, competence, fitness, social, appearance) on mental health and their indirect effects through MVPA in adolescents. A total of 424 participants (57.1% females) ages 14-15 years from the longitudinal MATCH study were included. Mediation analyses, based on the counterfactual framework, assessed the natural direct effect of PA motives on mental health, and the natural indirect effects through MVPA. Separate models were conducted for each PA motive. Natural direct effects were observed for enjoyment ( β ̂ $$ \hat{\beta} $$ [95%CI] = 2.12 [0.34, 3.90]), competence ( β ̂ $$ \hat{\beta} $$ [95%CI] = 1.58[0.28, 2.88]), fitness ( β ̂ $$ \hat{\beta} $$ [95%CI] = 1.42[0.04, 2.80]), and social ( β ̂ $$ \hat{\beta} $$ [95%CI] = 2.32[1.03, 3.60]) motives. No natural direct effects were observed for appearance motives. A natural indirect effect through MVPA was observed for fitness motives, and no other natural indirect effects were found. Interventions and public health strategies in adolescents need to acknowledge the importance of enjoyment, competence social and fitness motives in PA to promote mental health, and integrate specific recommendations on the importance of the reasons why adolescents participate in PA.

Secular trends in the incidence of eating disorders in China from 1990 to 2017: a joinpoint and age-period-cohort analysis

BACKGROUND

Eating disorders (ED) have increasingly become a global topic of concern for public health. A better understanding of ED incidence is a basic requirement for improving its management. However, the temporal trend of ED incidence in China is still unknown.

METHODS

The incidence rates of ED from 1990 to 2017 were collected from the Global Burden of Disease Study 2017 database according to the following: subtype, i.e. anorexia nervosa (AN) and bulimia nervosa (BN); sex; and age group. The average annual percent changes and relative risks were calculated using joinpoint regression and the age-period-cohort model, respectively.

RESULTS

From 1990 to 2017, age-standardized incidence rates of ED continued to increase in males and females, and this variation trend was observed in AN and BN. Joinpoint regression analysis showed that the incidence rates increased in all age groups. Adolescents had the highest risk of developing ED, followed by young adults. Age effects were the most influential risk factor for ED incidence. Period effects showed that the risk of developing ED continuously increased with increasing time periods in BN, but not in ED and AN. Concerning the cohort effects, people born after the 1990s presented a higher risk of ED, though they presented a lower risk of BN as compared to the whole cohort.

CONCLUSIONS

ED incidence rates continue to increase in China, particularly among adolescents and young adults. Further etiological studies are needed to explain these increases and to facilitate the early identification of high-risk individuals.

Elucidating early pubertal timing effects on disordered eating symptoms in young adult women

INTRODUCTION

Early pubertal timing increases risk for disordered eating (DE) in females, but the extent to which associations persist after puberty and are relevant to all types of DE symptoms is unclear. Factors that link pubertal timing and DE also remain unknown, although leading theories posit that adiposity and body-focused psychosocial factors play a key role. Thus, this study examined pubertal timing effects on several types of DE symptoms in young adult women and evaluated whether body mass index (BMI), pressures for thinness, thin-ideal internalization, and/or history of weight-based teasing account for such associations.

METHODS

This study included a racially and ethnically diverse sample of 342 female college students (M_age = 20.44, SD = 3.46). Women retrospectively reported their age at onset of menses, which served as the pubertal timing indicator, and completed self-report questionnaires on DE symptoms, perceived pressures for thinness, thin-ideal internalization, and history of weight-based teasing. BMI was calculated from height/weight measurements.

RESULTS

Earlier pubertal timing was associated with body dissatisfaction and binge eating, but not other DE symptoms (dieting, excessive exercise, muscle building) in young adult women. BMI accounted for pubertal timing effects on body dissatisfaction, whereas none of the examined factors explained pubertal timing effects on binge eating.

CONCLUSIONS

Earlier pubertal timing may exert long-term effects on only some DE symptoms in women, and the etiologic factors underlying pubertal timing effects on DE outcomes may differ across symptom types.

Mediating Effects of Intimacy Between Body Talk and Girls' Body Dissatisfaction: The Forgotten Sibling Relationship

Teasing and pressure from family members influences the development of body dissatisfaction. Body dissatisfaction is a common experience for girls and can lead to eating disorders. However, most body image disturbance research to date neglects the possible influence of siblings. In light of this, the present study investigated the associations between sibling negative appearance-based talk, intimacy, and body dissatisfaction. The sample consisted of 113 mostly White, female adolescents, whose ages ranged from 12 to 19 years with a mean age of 14.85 (SD = 1.62). This study first examined direct associations between negative body talk, including appearance related teasing and pressure from siblings, and girls' body dissatisfaction. Second, indirect effects models with intimacy included were examined. There were significant direct links between appearance related pressure from siblings and body dissatisfaction, and significant indirect effects such that sibling teasing and pressure were associated with sibling intimacy, which was associated with body dissatisfaction. These results indicate that siblings play an important role in the development of girls' body dissatisfaction.

Factors associated with disordered feeding among high school students in Kerman City, Iran

BACKGROUND

Mental health problems and disordered eating, are more common in adolescents. This study investigated relationship between mental health and disordered eating in high school girls in southeast Iran.

METHODS

This cross-sectional descriptive correlational study accomplished in high school girls of Kerman at the southeast of Iran in 2019. Using three parts demographic, Standard General Health Questionnaire (GHQ-28) and Eating Attitudes questionnaire, (Eat-26) with three subscales: eating habits, desire to eat and oral control. We investigated high school girl's mental health and relationship with disordered eating with cluster sampling method (600 high school girl). Multivariate logistic regression was used to determine the association between significant variables and the risk of General Health (Yes/No) and Eating attitude (Yes/No). Spearman correlation test, Mann-Witheny U test and Kruskal-Wallis test were used, and Significant level was considered at P < 0.05.

RESULTS

A direct and significant relationship between mental health and disordered eating (r = 0/19, P < 0.001). In other words, the higher the mental health disorder score, the higher the disordered eating score, and the higher disordered eating score, the higher mental problems. There was a direct and significant relationship between mental health and all aspects of disordered eating including eating habits (r = 0/12, P < 0.05), desire to eat (r = 0/1, P < 0.05) and oral control (r = 0/14, P < 0.001).

CONCLUSIONS

It seems that the disordered eating and mental health have a determinant role in relationship with each other. Therefore, prevention and health promotion programs should be implemented to improve female adolescent mental health and reduce disordered eating.

Psychometric validation of the Japanese version of the Functionality Appreciation Scale (FAS)

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a widely adopted measure to assess appreciation for one's body and its capacity. In this study, we performed a psychometric validation of the Japanese translation of the FAS. Participants included an online sample of 750 Japanese individuals (20-70 years old), who completed the FAS and other previously validated measures of body appreciation, intuitive eating, gratitude, self-esteem, and life satisfaction. Moreover, the survey was conducted twice, 3 weeks apart, to determine test-retest reliability. Exploratory factor analyses replicated the unidimensional factor structure of the FAS, which was also verified by the confirmatory factor analysis. FAS scores had gender invariance, and demonstrated good internal consistency and test-retest reliability over the 3-week period. In addition, further analyzes indicated adequate construct, and incremental validity. These findings indicate that the Japanese version of FAS demonstrates good psychometric properties, and can be used to examine the importance of functionality appreciation for enhancing positive body image and healthy eating.

eLoriCorps Immersive Body Rating Scale and eLoriCorps Mobile Versions: Validation to Assess Body Image Disturbances from Allocentric and Egocentric Perspectives in a Nonclinical Sample of Adolescents

A growing number of studies have used virtual reality (VR) for the assessment and treatment of body image disturbances (BIDs). This study, conducted in a community sample of adolescents, documents the convergent and discriminant validity between (a) the traditional paper-based Figure Rating Scale (paper-based FRS), (b) the VR-based Body Rating Scale (eLoriCorps-IBRS 1.1), and (c) the mobile app-based Body Rating Scale (eLoriCorps-IBRS 1.1-Mobile). A total of 93 adolescents (14 to 18 years old) participated in the study. Body dissatisfaction and body distortion were assessed through the paper-based FRS, the eLoriCorps-IBRS 1.1 and the eLoriCorps-IBRS 1.1-Mobile. Eating disorder symptoms, body image avoidance, and social physique anxiety were also measured. Correlation analyses were performed. Overall, the results showed a good and statistically significant convergence between allocentric perspectives as measured by the paper-based FRS, the eLoriCorps-IBRS 1.1 and the eLoriCorps-IBRS 1.1-Mobile. As expected, the egocentric perspective measured in VR produced different results from the allocentric perspective, and from cognitive–attitudinal–affective dimensions of BIDs, with the exception of body distortion. These differences support the discriminant validity of the egocentric perspective of eLoriCorps-IBRS 1.1 and are consistent with emerging evidence, highlighting a difference between experiencing the body from an egocentric (i.e., the body as a subject) and allocentric (i.e., the body as an object) perspective. The egocentric perspective could reflect a perceptual–sensory–affective construction of BIDs, whereas allocentric measures seem to be more related to a cognitive–affective–attitudinal construction of BIDs. Moreover, the results support the validity of the eLoriCorps-IBRS 1.1-Mobile with promising perspectives of implementation among young populations.

Prevention of Unhealthy Weight, Disordered Eating, and Poor Body Image in Children. Perspectives From Norwegian Parents and Healthcare Professionals

BACKGROUND

Childhood obesity (ChO) and eating disorders are on the rise, with concerning effects on health. Early prevention is essential as interventions after problems arise are costly and with a low success rate. In Norway, prevention of ChO has been largely weight-centered, without desired effects. Confident Body, Confident Child (CBCC) is a universal program aimed at preventing ChO, disturbed eating, and body image problems through a health-centered intervention for parents of children between 2 and 6 years. The current study is part of a cultural adaptation and translation of CBCC into Norwegian.

METHODS

Focus groups with parents (n = 16) and professionals (n = 11) were held around healthy eating, activity, and body image, with an emphasis on possible barriers for prevention as well as approaches considered helpful. The interviews were analyzed using interpretative phenomenological analysis.

RESULTS

Parents and professionals described parental stress connected to high standards, conflicting information, and parental comparison. A narrowing sense of normality around healthy living was described with little flexibility resulting in "all-or-nothing" thinking. Parents were anxious to say or do the wrong thing when regulating children's food intake and when faced with comments about appearance. Parents and professionals described parental concern around children not eating enough, and professionals described an increase in parents using food as regulation. Both parents and professionals expressed that having a child with overweight was tied to a sense of failure and shame. Interventions related to overweight seemed to increase stress and shame, further complicating follow-up. As an alternative, parents and professionals expressed a desire for interventions with normalizing information around "good-enough" parenting related to food and weight.

DISCUSSION

The described fear of doing something wrong and lack of flexibility is interpreted within a stress-sensitive understanding, where stress and shame can influence parents toward mobilizing action or disengagement, presenting as dichotomous behaviors of "all-or-nothing".

CONCLUSION

Interventions that can normalize parental concerns in a non-moralizing way may reduce stress and shame. CBCC addresses all the major concerns raised in this study, providing parents with evidence-based information they can implement into everyday life. The Norwegian cultural adaptation added extra emphasis on normalization and shame-reduction.
