Abstract
In 2022 the British government made calorie labels on menus a legal requirement to encourage healthier food choices while dining out. Yet, little research has explored perceptions of calorie labels on menus in the United Kingdom or tested whether there may be groups of people vulnerable to potential negative effects of calorie labels, such as those with body dissatisfaction. This between-subjects, convergent mixed-methods study addressed these enquiries. Participants were 562 adults who completed an online survey where hypothetical food orders were made from a menu. The study found that participants who viewed a menu with calorie labels ordered fewer calories. Quantitative results did not find that participants with higher levels of body dissatisfaction were at significantly greater odds of using calorie labels to order fewer calories. However, our qualitative (thematic) analysis revealed that experiences of calorie labels could be shaped by body image concerns. Themes further drew on how calorie labels were empowering, but there were also concerns about their oversimplicity. Findings are discussed in relation to implications for future calorie labelling policies. Given the inconsistent findings amongst the limited amount of literature investigating the role of body dissatisfaction in how calorie labels are used, future research is crucial. In the meantime, as a cautionary measure, clinicians involved in supporting individuals with body or food-related concerns should be aware of the challenges their clients may experience in facing calorie labels on menus when dining out.

Subclinical patterns of disordered eating behaviors in the daily life of adolescents and young adults from the general population. Child Adolesc Psychiatry Ment Health 2024; 18:69. [PMID: 38845025 PMCID: PMC11157754 DOI: 10.1186/s13034-024-00752-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Accepted: 05/15/2024] [Indexed: 06/09/2024] Open
Abstract
BACKGROUND Disordered eating behaviors (DEBs), a risk factor for the development of eating disorders (EDs), are prevalent in young people and different DEBs frequently co-occur. Previous studies on DEB-patterns have largely used traditional retrospective questionnaires to assess DEBs. In addition, most previous studies did not specifically exclude individuals with clinical EDs, which limits current knowledge concerning purely subclinical patterns of DEBs. In the present study, we aimed to explore phenotypes and group sizes of subclinical patterns of DEBs reported in everyday life via smartphone-based ecological momentary assessment (EMA) in adolescents and young adults from the general population without lifetime EDs. In secondary analyses, we further aimed to investigate whether DEB-patterns would be associated with additional previously identified risk factors for ED-development. METHODS EMA was conducted in a community sample of 14-21-year-olds from Dresden, Germany, over four days for up to eight times a day and covered engagement in four DEBs: skipping eating, restrained eating, eating large amounts of food, and loss-of-control eating. Data were analyzed from N = 966 individuals without lifetime EDs with an EMA compliance rate of at least 50% (81.9% of the total sample; average compliance: 84.6%). Latent profile analyses were performed to identify subclinical patterns of DEBs, stratified by sex. Associations between symptomatic profiles and ED-risk factors were tested via regression analyses. RESULTS Based on theoretical deliberations, statistical indices, interpretability, and parsimony, a three-profile solution, namely no DEBs, high-mixed DEBs, and low-mixed DEBs, was selected for both sexes. Both symptomatic profiles in both sexes were associated with more unfavorable manifestations in additional ED risk factors compared to the no DEBs profile, with the highest number of associations being observed in the female high-mixed profile. CONCLUSIONS The present findings suggest that problematic manifestations of DEBs in young people may occur even in the absence of an ED diagnosis and that they are associated with additional risk factors for EDs, warranting increased efforts in targeted prevention, early identification and intervention in order to counteract symptom progression.

Abstract
Pregnancy and postpartum represent a critical transition period for changes in eating disorder (ED) symptoms and depression. Past research has established a relationship between ED and depressive symptoms during pregnancy. However, changes in depression and ED symptom across stages of pregnancy and postpartum, and factors that influence this relationship, remain understudied. Social factors and self-evaluative factors may be important given rapidly changing social pressures and expectations during this transitional time. The current study (N = 454 pregnant women) examined (1) differences in ED and depressive symptoms across pregnancy and postpartum and (2) whether social factors (social appearance anxiety; social support) and self-evaluative factors (maladaptive perfectionism; self-compassion) moderate the relationship between depression and ED symptoms cross-sectionally and prospectively. Study aims, hypotheses, and data analysis were preregistered on the Open Science Foundation (osf.io). This study did not identify differences in ED or depression symptoms across women at different stages of pregnancy; however, depression symptoms significantly improved within individuals from pregnancy to postpartum. ED symptoms and all social and self-evaluative factors were uniquely associated with depression during pregnancy. ED symptoms, maladaptive perfectionism, social appearance anxiety, and self-compassion during pregnancy significantly predicted postpartum depression, when accounting for prenatal depression. During pregnancy, but not postpartum, when social support and self-compassion were low, and when maladaptive perfectionism was high, there was a stronger relationship between ED and depression symptoms. ED symptoms and social and self-evaluative factors could be targeted in routine medical care and stepped-care interventions to improve maternal mental healthcare and prevent postpartum depression.

Abstract
Fasting and negative urgency (the disposition to act rashly when distressed) are risk factors for binge eating. It may be that each influences the other over time to predict binge eating. OBJECTIVE This study tested whether (1) fasting predicts binge eating through negative urgency, and (2) negative urgency predicts binge eating through fasting. METHOD Path analysis and mediation tests were used to investigate objectives in n = 302 college women assessed three times over eight months. We controlled for each variable at the previous time point, and concurrent negative affect and body mass index at each time point. RESULTS Time 1 (T1) fasting predicted elevated negative urgency three months later at Time 2 (T2) and T2 negative urgency predicted increases in binge eating five months later at Time 3 (T3). T2 negative urgency mediated the relationship between T1 fasting and T3 binge eating. T1 negative urgency predicted increases in T2 fasting, which then predicted increases in T3 binge eating. T2 fasting mediated the relationship between T1 negative urgency and T3 binge eating. DISCUSSION Findings suggest fasting and negative urgency transact to predict binge eating among college women. Interventions targeting negative urgency may prevent or reduce both fasting and binge eating.

Abstract
Introduction Eating disorders (EDs) are serious psychological problems that affect not only the individual, but also their entire environment. The prevalence rates of EDs are higher among the adolescent population. A better understanding of ED risk factors is essential to design effective prevention and intervention programs that focus beyond the areas of weight and appearance. Methods The main objective of this systematic review was to identify the risk factors of EDs and provide a comprehensive approach, analyzing the interplay between individuals, their inner circle, and the society characteristics. The Web of Science, Scopus, CENTRAL and PsycInfo databases were searched. Results The initial search produced 8,178 references. After removing duplicates and performing the selection process by three independent reviewers, 42 articles were included in the systematic review according to the pre-specified inclusion criteria. The results suggest the relevance of society and the inner circle on the development of EDs. Discussion The internalization of the thin ideal, promoted by the current society, and living in an unsupportive, unaffectionate, non-cohesive environment were associated with the onset of EDs symptomatology. Other associated variables with this ED indicator were poor-quality relationships and feeling judged about appearance. These aspects seem to be essential for the development of individual characteristics like self-esteem or adaptative coping during adolescence. This systematic review has shown the complex etiology of EDs and the relevance of the interplay between the different areas involved. Furthermore, this information could be relevant to improve the design of innovative and more effective prevention and intervention programs.

Abstract
Human agents immersed in metaverse technologies such as virtual reality (VR) are routinely disconnected from their actual physical appearance and embodied in another virtual body, referred to as self-avatar. Such body transformations can have implications for patients with eating disorders, or persons with extreme body dissatisfaction (BD). Changes in BD, weight anxiety, or body image are theoretically linked to visual selective attention, which can be measured with eye tracking. In the present study, 43 women with high or low BD were immersed in animated body weight-manipulated self-avatars in VR. Before a brief mirror exposure with their self-avatars, they experienced synchronous visuomotor and visuo-tactile contingencies in VR to increase embodiment, delivered through small movement exercises with real-time animation from first-person perspective and passive haptics. In a crossover study design, self-avatar weight was manipulated (normal weight vs. overweight) in both groups (low BD vs. high BD), and subjective experience was assessed before and after exposure. In contrast to our hypotheses, BD was not affected by the self-avatar condition. Embodiment decreased during mirror exposure, possibly due to the avatars wearing head-mounted displays. Interestingly, disembodiment was stronger in women with low BD. Furthermore, eye tracking showed that participants with high BD looked longer at weight-related body parts when immersed in the overweight self-avatar, whereas participants with low BD looked longer at weight-related body parts when immersed in the normal weight self-avatar. Overall, the results support body-specific visual attention and suggest that particularly participants with low BD show stronger disembodiment during self-avatar mirror exposure, possibly alleviating momentary body experience.

Abstract
INTRODUCTION Many children experience weight-based bullying (WB), when individuals are treated poorly or demeaned because of weight. WB has negative mental and physical health consequences. The current study examined how children's experiences of different forms of WB (verbal, social, physical, cyber) were associated with impaired functioning in school, social life, and family life. METHODS Data were collected in Spring 2021. Participants (N = 224) were parents of a school-aged child and lived in the United States. Sixty percent of parents were mothers and 72% of parents self-identified as White. They completed surveys regarding weight, eating, and bullying. RESULTS Social and cyber WB were associated with clinically significant impairment for both children and parents. Children who experienced social and physical WB were more likely to skip school, whereas physical and cyber WB were associated with skipping a particular class. All forms of bullying were associated with skipping gym class. Social and cyber WB were associated with isolating. Cyber WB was associated with all disordered eating behaviors. In addition, physical WB was associated with binge eating, social WB was associated with purging, and verbal WB was associated with secretive eating. DISCUSSION Victims of WB experience impairment in school, social life, and family life, absenteeism, and disordered eating. It is essential to develop approaches to address WB in its various forms to identify strategies for reducing and preventing WB across various levels of influence, including peer groups, schools, and families.

Abstract
OBJECTIVE Evidence linking childhood body mass index (BMI) with subsequent eating disorders is equivocal. Potential explanations include different study populations and size, and that anorexia nervosa (AN) and bulimia nervosa (BN) should be studied separately. We examined whether birthweight and childhood BMI were associated with subsequent risk of AN and BN in girls. METHOD We included 68,793 girls from the Copenhagen School Health Records Register born between 1960 and 1996 with information on birthweight and measured weights and heights obtained from school health examinations at ages 6-15 years. Diagnoses of AN and BN were retrieved from Danish nationwide patient registers. We used Cox proportional hazards regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS We identified 355 cases of AN (median age: 19.0) and 273 cases of BN (median age: 21.8). Higher childhood BMI was linearly associated with decreasing risk of AN and increasing risk of BN at all childhood ages. At age 6, the HR for AN was 0.85 (95% CI: 0.74-0.97) per BMI z-score and the HR for BN was 1.78 (95% CI: 1.50-2.11) per BMI z-score. Birthweight >3.75 kg was associated with increased risk of BN compared to a birthweight of 3.26-3.75 kg. CONCLUSION Higher BMI in girls at ages 6-15 years was associated with decreasing risk of AN and increasing risk of BN. Premorbid BMI could be relevant for the etiology of AN and BN, and in identifying high risk individuals. PUBLIC SIGNIFICANCE Eating disorders are associated with elevated mortality, especially AN. Using a cohort of Copenhagen school children, we linked information on BMI at ages 6-15 years for 68,793 girls with nationwide patient registers. Low childhood BMI was associated with increased risk of AN, whereas high childhood BMI was associated with increased risk of BN. These findings may assist clinicians in identifying individuals at high-risk of these diseases.

Abstract
In recent years, investigators have focused on neural vulnerability factors that increase the risk of unhealthy weight gain, which has provided a useful organizing structure for obesity neuroscience research. However, this framework, and much of the research it has informed, has given limited attention to contextual factors that may interact with key vulnerabilities to impact eating behaviors and weight gain. To fill this gap, we propose a Contextualized Neural Vulnerabilities Model of Obesity, extending the existing theory to more intentionally incorporate contextual factors that are hypothesized to interact with neural vulnerabilities in shaping eating behaviors and weight trajectories. We begin by providing an overview of the Neural Vulnerabilities Model of Obesity, and briefly review supporting evidence. Next, we suggest opportunities to add contextual considerations to the model, including incorporating environmental and developmental context, emphasizing how contextual factors may interact with neural vulnerabilities to impact eating and weight. We then synthesize earlier models and new extensions to describe a Contextualized Neural Vulnerabilities Model of Obesity with three interacting components-food reward sensitivity, top-down regulation, and environmental factors-all within a developmental framework that highlights adolescence as a key period. Finally, we propose critical research questions arising from the framework, as well as opportunities to inform novel interventions.

Abstract
BACKGROUND Despite a wide range of proposed risk factors and theoretical models, prediction of eating disorder (ED) onset remains poor. This study undertook the first comparison of two machine learning (ML) approaches [penalised logistic regression (LASSO), and prediction rule ensembles (PREs)] to conventional logistic regression (LR) models to enhance prediction of ED onset and differential ED diagnoses from a range of putative risk factors. METHOD Data were part of a European Project and comprised 1402 participants, 642 ED patients [52% with anorexia nervosa (AN) and 40% with bulimia nervosa (BN)] and 760 controls. The Cross-Cultural Risk Factor Questionnaire, which assesses retrospectively a range of sociocultural and psychological ED risk factors occurring before the age of 12 years (46 predictors in total), was used. RESULTS All three statistical approaches had satisfactory model accuracy, with an average area under the curve (AUC) of 86% for predicting ED onset and 70% for predicting AN v. BN. Predictive performance was greatest for the two regression methods (LR and LASSO), although the PRE technique relied on fewer predictors with comparable accuracy. The individual risk factors differed depending on the outcome classification (EDs v. non-EDs and AN v. BN). CONCLUSIONS Even though the conventional LR performed comparably to the ML approaches in terms of predictive accuracy, the ML methods produced more parsimonious predictive models. ML approaches offer a viable way to modify screening practices for ED risk that balance accuracy against participant burden.

Abstract
BACKGROUND Clinical, epidemiological, and genetic findings support an overlap between eating disorders, obsessive-compulsive disorder (OCD), and anxiety symptoms. However, little research has examined the role of genetics in the expression of underlying phenotypes. We investigated whether the anorexia nervosa (AN), OCD, or AN/OCD transdiagnostic polygenic scores (PGS) predict eating disorder, OCD, and anxiety symptoms in a large developmental cohort in a sex-specific manner. METHODS Using summary statistics from Psychiatric Genomics Consortium AN and OCD genome-wide association studies, we conducted an AN/OCD transdiagnostic genome-wide association meta-analysis. We then calculated AN, OCD, and AN/OCD PGS in participants from the Avon Longitudinal Study of Parents and Children to predict eating disorder, OCD, and anxiety symptoms, stratified by sex (combined N = 3212-5369 per phenotype). RESULTS The PGS prediction of eating disorder, OCD, and anxiety phenotypes differed between sexes, although effect sizes were small. AN and AN/OCD PGS played a more prominent role in predicting eating disorder and anxiety risk than OCD PGS, especially in girls. AN/OCD PGS provided a small boost over AN PGS in the prediction of some anxiety symptoms. All three PGS predicted higher compulsive exercise across different developmental timepoints [β = 0.03 (s.e. = 0.01) for AN and AN/OCD PGS at age 14; β = 0.05 (s.e. = 0.02) for OCD PGS at age 16] in girls. CONCLUSIONS Compulsive exercise may have a transdiagnostic genetic etiology, and AN genetic risk may play a role in the presence of anxiety symptoms. Converging with prior twin literature, our results also suggest that some of the contribution of genetic risk may be sex-specific.

Abstract
BACKGROUND Existing internet-based prevention and treatment programmes for binge eating are composed of multiple distinct modules that are designed to target a broad range of risk or maintaining factors. Such multi-modular programmes (1) may be unnecessarily long for those who do not require a full course of intervention and (2) make it difficult to distinguish those techniques that are effective from those that are redundant. Since dietary restraint is a well-replicated risk and maintaining factor for binge eating, we developed an internet- and app-based intervention composed solely of cognitive-behavioural techniques designed to modify dietary restraint as a mechanism to target binge eating. We tested the efficacy of this combined selective and indicated prevention programme in 403 participants, most of whom were highly symptomatic (90% reported binge eating once per week). METHOD Participants were randomly assigned to the internet intervention (n = 201) or an informational control group (n = 202). The primary outcome was objective binge-eating frequency. Secondary outcomes were indices of dietary restraint, shape, weight, and eating concerns, subjective binge eating, disinhibition, and psychological distress. Analyses were intention-to-treat. RESULTS Intervention participants reported greater reductions in objective binge-eating episodes compared to the control group at post-test (small effect size). Significant effects were also observed on each of the secondary outcomes (small to large effect sizes). Improvements were sustained at 8 week follow-up. CONCLUSIONS Highly focused digital interventions that target one central risk/maintaining factor may be sufficient to induce meaningful change in core eating disorder symptoms.

Abstract
Research shows negative correlations between media exposure of body images in the context of hegemonic beauty ideals and body satisfaction. The present study deals with the underlying mechanisms and the effects of different exposure contents. In the online experimental study, a sample consisting of 226 individuals (82.3% female, 17.7% male) received a three-minute exposure to Instagram images of women and men in the context of either hegemonic beauty ideals in the experimental group or body diversity in the control group. A conducted Mixed ANOVA with repeated measures showed significant group differences, including an increase in body dissatisfaction in the experimental group and a reduction in the control group after exposure. Statistically significant detrimental effects of exposure to images in the experimental group on women's state mood as well as descriptive similar tendencies on men's state mood were found. Moderating effects of the tendency to make upward social comparisons and the internalization of the gender-specific beauty ideal on the relationship between exposure content and the change scores of body dissatisfaction were found. Furthermore, a mediation model was calculated to investigate the effect of exposure content on post-measurement of body dissatisfaction, using the constructs "comparison processes regarding sexual attractiveness" and "assessment of one's own sexual attractiveness" as mediators. The model did not yield significant mediation, although significant relationships were found between the model components. Exploratory analyses were conducted on the influence of the assessment of one's own sexual attractiveness on related social comparisons and the intensity of engagement with Instagram content as a predictor of body dissatisfaction. The results highlight the relevance for psychoeducational purposes of addressing a critical engagement with depicted beauty ideals in social media. Moreover, the study proposes body diversity as an alternative content that can have a positive impact on body satisfaction, which can be actively sought during the individual Instagram user experience.

Abstract
Twin studies demonstrate significant environmental influences and a lack of genetic effects on disordered eating before puberty in girls. However, genetic factors could act indirectly through passive gene-environment correlations (rGE; correlations between parents' genes and an environment shaped by those genes) that inflate environmental (but not genetic) estimates. The only study to explore passive rGE did not find significant effects, but the full range of parental phenotypes (e.g., internalizing symptoms) that could impact daughters' disordered eating was not examined. We addressed this gap by exploring whether parents' internalizing symptoms (e.g., anxiety, depressive symptoms) contribute to daughters' eating pathology through passive rGE. Participants were female twin pairs (aged 8-14 years; M = 10.44) in pre-early puberty and their biological parents (n = 279 families) from the Michigan State University Twin Registry. Nuclear twin family models explored passive rGE for parents' internalizing traits/symptoms and twins' overall eating disorder symptoms. No evidence for passive rGE was found. Instead, environmental factors that create similarities between co-twins (but not with their parents) and unique environmental factors were important. In pre-early puberty, genetic factors do not influence daughters' disordered eating, even indirectly through passive rGE. Future research should explore sibling-specific and unique environmental factors during this critical developmental period.

Abstract
Emerging theoretical and empirical evidence indicates that negative body image might be implicated in the onset or maintenance of ON symptoms. However, existing research investigating associations between negative body image and ON is limited to cross-sectional designs and has failed to consider the independent role of distinct components of body image. To overcome these limitations, the present study examined the prospective associations between five components of body image (i.e., overvaluation, dissatisfaction, preoccupation, body checking, and body image avoidance) and ON symptoms in community-based adult women. Participants were assessed at baseline and at a three-month follow-up, with 558 women included in the final analyses. After adjusting for baseline ON symptoms, higher scores on each of the five body image components at baseline significantly predicted greater increases in ON symptoms in univariate analyses. However, in multivariate analyses, overvaluation with weight and shape was the only component of body image to uniquely predict ON symptoms. Findings suggest that certain components of negative body image may increase the risk for ON symptoms. Findings also lend support to recent proposals that ON may be better viewed as a variant of an existing eating disorder, given that both appear to share similar underlying risk factors.

Abstract
BACKGROUND Theoretical models highlight the importance of emotion dysregulation as a key risk and maintaining factor for eating disorders. However, most studies testing these theories are cross-sectional. It remains unclear which dimensions of emotion dysregulation account for the onset and persistence of eating disorder behaviours over time. METHODS To address these gaps, data were analyzed from 1321 adult women who completed study measures at baseline and eight-month follow-up. The dimensions of emotion dysregulation assessed were five subscales from the abbreviated 16-item Difficulties in Emotion Regulation Scale. Outcomes included the onset (versus asymptomatic) and persistence (versus remission) of binge eating and compensatory behaviours. RESULTS Univariate logistic regressions showed that, among initially asymptomatic women, higher baseline levels of each emotion dysregulation dimension (except the "goals" subscale) predicted the onset of binge eating and compensatory behaviours at follow-up. Each dimension also predicted the persistence of compensatory behaviours at follow-up among women endorsing these behaviours at baseline, while the "impulse", "strategies", and "non-acceptance" dimensions predicted the persistence of binge eating. In multivariate analyses, only the "strategies" dimension predicted the onset and persistence of binge eating, while the "non-acceptance" dimension predicted the onset and persistence of compensatory behaviours. LIMITATIONS Only a limited number of emotion dysregulation dimensions were tested. CONCLUSION Findings demonstrate the importance of emotion dysregulation dimensions in accounting for the onset and maintenance of eating disorder behaviours. The delivery of specific intervention strategies designed to address emotion dysregulation may depend on the risk and symptom profile of an individual.

Abstract
PURPOSE This study sought to explore the associations between Intuitive Eating (IE), eating disorder (ED) symptom severity, and body image-related cognitive fusion within a clinical sample. IE was also examined as a possible mediator in the relationship between body image-related fusion and ED symptoms. METHODS This study includes cross-sectional analyses with data from 100 adult females and 75 adolescent females seeking residential treatment for an ED. Self-reported demographic information, ED symptoms, IE behaviors, and body image-related cognitive fusion were collected from participants within the first week of treatment following admission to the same residential ED treatment facility. RESULTS ED symptom severity was significantly negatively associated with three of the four domains of IE; unconditional permission to eat, reliance on hunger and satiety cues, and body-food choice congruence. A significant mediational effect of IE on the relationship between body image-related fusion and ED symptoms through IE behaviors was observed (β = 11.3, SE = 0.003, p < 0.001). This effect was only observed for the unconditional permission to eat (β = 0.13, p = 0.003) and reliance on hunger and satiety cues (β = 0.10, p = 0.005) domains of IE when the domains were subsequently analyzed individually. CONCLUSION Unconditional permission to eat and reliance on hunger and satiety cues appear to be particularly influential domains of IE in the relationship between body image-related fusion and ED symptom severity. It is possible that changes in these IE domains may be mechanisms through which body image-related fusion influences ED symptoms. Future longitudinal research is needed to better understand the relationship between body image-related cognitive fusion and IE and the potential for targeting these constructs specifically in the context of ED treatment.

Abstract
Growth deviating from the norm during childhood has been associated with anorexia nervosa (AN) and obesity later in life. In this study, we examined whether polygenic scores (PGSs) for AN and BMI are associated with growth trajectories spanning the first two decades of life. AN PGSs and BMI PGSs were calculated for participants of the Avon Longitudinal Study of Parents and Children (ALSPAC; n = 8,654). Using generalized (mixed) linear models, we associated PGSs with trajectories of weight, height, body mass index (BMI), fat mass index (FMI), lean mass index (LMI), and bone mineral density (BMD). Female participants with AN PGSs one standard deviation (SD) higher had, on average, 0.004% slower growth in BMI between the ages 6.5 and 24 years and a 0.4% slower gain in BMD between the ages 10 and 24 years. Higher BMI PGSs were associated with faster growth for BMI, FMI, LMI, BMD, and weight trajectories in both sexes throughout childhood. Female participants with both a high AN PGS and a low BMI PGS showed slower growth compared to those with both a low AN PGS and a low BMI PGS. We conclude that AN PGSs and BMI PGSs have detectable sex-specific effects on growth trajectories. Female participants with a high AN PGS and low BMI PGS likely constitute a high-risk group for AN, as their growth was slower compared to their peers with high PGSs on both traits. Further research is needed to better understand how the AN PGS and the BMI PGS co-influence growth during childhood and whether a high BMI PGS can mitigate the effects of a high AN PGS.

Abstract
OBJECTIVE Gender and sexual identity constitute social categories that have been found to be important when identifying persons at risk for eating disorders (ED), since prevalence rates are especially high for women as well as persons of gender and sexual minorities. The objective of this study is to enhance the understanding of how these social categories relate to ED development. METHOD A qualitative, inductive approach was used in order to develop empirically grounded hypotheses about gendered aspects in ED development. Data are 14 narrative interviews with persons of diverse sexual and gender identities who recovered from anorexia or bulimia nervosa. Interviews were analyzed in depth using Grounded Theory Methodology and Voice Centered Listening. RESULTS Results suggest that social experiences related to female gender, as well as social experiences related to non-compliance with social gender norms, can be important for ED development. Those social experiences were described as influencing participants' self-worth, body image and self-regulatory strategies, which were connected to ED symptomatology. DISCUSSION Future research should further validate the gendered aspects presented in this paper, since including a broader array of gendered social aspects in ED research might help to improve etiological understanding and prevention methods. PUBLIC SIGNIFICANCE STATEMENT This study contributes a special perspective to research on eating disorders and gender, because it is based on first-person perspectives of formerly affected persons and integrates the experiences of persons with different gender and sexual identities. Participants described four categories of gendered social experiences relevant for their eating disorders. We discuss the potential of these categories to guide future research on the development of eating disorders and their prevention.

Abstract
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.

Abstract
OBJECTIVE Reinforcement Sensitivity Theory (RST) provides a theoretical foundation associated with various approach and avoidance behaviors and individual personality differences. Sensitivity to reward and punishment, two neural systems within the RST have been significantly associated with bingeing and purging behaviors. However, inconsistent findings are observed and specific factors mediating these relationships are not well understood. Deficits in emotion regulation may account for these relationships, as both negative urgency and distress tolerance have been independently associated with bulimia behaviors. Thus, this is an area that requires further investigation. METHOD The current study utilized various self-report inventories, including the Eating Disorder Inventory-3rd Edition to measure bulimia symptoms, as well as measures of negative affect, sensitivity to reward and punishment, distress tolerance, and negative urgency. These measures were used to assess whether distress tolerance and negative urgency mediated associations between sensitivity to reward and punishment and bulimia symptoms in a community sample of 394 young adults ranging from the ages of 18 to 25. RESULTS As expected, sensitivity to reward and punishment were significantly associated with decreased distress tolerance. Distress tolerance was also directly associated with greater negative urgency, which was significantly associated with increased bulimia symptoms. Consistent with hypotheses, indirect associations between sensitivity to reward and sensitivity to punishment to bulimia symptoms via distress tolerance and negative urgency were observed, controlling for gender and negative affect. DISCUSSION Results contribute to understanding specific contributions of risk factors within the relationship of sensitivity to reward and punishment and bulimia symptoms, measured by the EDI-3. Novel to existing literature, results indicate that reinforcement sensitivity significantly contributes to emotion regulation deficits. Thus, these findings may have important implications for understanding the development and treatment of bulimia symptoms. LEVEL OF EVIDENCE Level V, based on descriptive, cross-sectional data.

Obesity (Silver Spring) 2022; 30:902-910. [PMID: 35333443 PMCID: PMC8969753 DOI: 10.1002/oby.23396] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Revised: 01/10/2022] [Accepted: 01/11/2022] [Indexed: 01/21/2023]
Abstract
OBJECTIVE The goal of this study was to determine whether the degree of weight loss after 6 months of a behavior-based intervention is related to baseline connectivity within two functional networks (FNs) of interest, FN1 and FN2, in a group of older adults with obesity. METHODS Baseline functional magnetic resonance imaging data were collected following an overnight fast in 71 older adults with obesity involved in a weight-loss intervention. Functional brain networks in a resting state and during a food-cue task were analyzed using a mixed-regression framework to examine the relationships between baseline networks and 6-month change in weight. RESULTS During the resting condition, the relationship of baseline brain functional connectivity and network clustering in FN1, which includes the visual cortex and sensorimotor areas, was significantly associated with 6-month weight loss. During the food-cue condition, 6-month weight loss was significantly associated with the relationship between baseline brain connectivity and network global efficiency in FN2, which includes executive control, attention, and limbic regions. CONCLUSION These findings provide further insight into complex functional circuits in the brain related to successful weight loss and may ultimately aid in developing tailored behavior-based treatment regimens that target specific brain circuitry.

Testing of a model for risk factors for eating disorders and higher weight among emerging adults: Baseline evaluation. Body Image 2022; 40:322-339.

Abstract
Although a range of risk factors have been identified for disordered eating and weight status, the breadth of risk factors have been rarely considered within a single, comprehensive model. The robustness of these findings across countries also remains an open question. The present study sampled 6272 participants aged 18-30 years from eight countries in an attempt to evaluate combined and unique predictors for these two conditions, and to explore possible cross-country differences in these models. Participants completed a range of demographic, biological, behavioral, psychological, and sociocultural measures to test a comprehensive model of the contributions of these predictors for disordered eating and weight-related constructs (binge eating, body mass index, compensatory behaviors, dietary restraint, drive for muscularity, and drive for leanness). Structural invariance testing within a multigroup path analysis framework revealed that a single model across the eight countries provided poor model fit. Freeing of 22% of parameters across countries provided excellent fit and a satisfactory compromise for country-invariant and country-variant parameters in the model. Overall, predictors accounted for between 15% and 60% of variance in the outcome measures, with lowest explained variance for the disordered eating outcomes. Significant unique contributions to prediction were observed for each of the five risk factor variable types and across the eight countries. Thus, the findings show strong support for this model as an explanatory framework of both disordered eating and weight status.

Abstract
OBJECTIVE Repetitive negative thinking (RNT) is associated with eating disorder (ED) symptoms, but few studies have evaluated how RNT may relate to specific ED behaviors (e.g., fasting, binge eating). Furthermore, little research has examined RNT in adolescent girls, a critical population for ED development. Concern over mistakes perfectionism (i.e., preoccupation with and overvaluation of errors) and social appearance anxiety are transdiagnostic risk factors for EDs that may be amplified by RNT, contributing to the development of ED behaviors. METHOD The current study (N = 332 female high school students) explored RNT in an adolescent sample and tested whether RNT was uniquely associated with fasting/binge eating and moderated the relationships between social appearance anxiety/perfectionism and fasting/binge eating. RESULTS RNT was not associated with fasting and did not significantly moderate the relationship between social appearance anxiety/perfectionism and fasting. RNT was positively associated with binge eating but did not moderate the relationship between social appearance anxiety/perfectionism and binge eating. CONCLUSIONS RNT may contribute differentially to specific ED behaviors such as fasting and binge eating during ED development. If replicated in prospective data, these findings suggest targeting RNT in adolescence may decrease binge eating.

Abstract
OBJECTIVE Establishing factors that protect against the onset of eating disorder symptoms is needed to identify critical intervention targets to inform the design of more potent prevention programs. Knowledge of robust protective factors is lacking, which might account for the limited effectiveness of existing prevention programs. As positive body image, intuitive eating, and self-compassion show protective potential, the present study tested whether these factors protect against the onset of a range of different eating disorder symptoms. METHOD Data were analyzed from 1,270 women who completed study measures at baseline and 8 months. Logistic regressions tested whether, among initially asymptomatic women, baseline and changes in positive body image components (body appreciation, body image flexibility, and functionality appreciation), intuitive eating, and self-compassion predicted the continued absence versus onset of seven core eating disorder symptoms at follow-up. RESULTS Each of the five factors at baseline was associated with a lower odds of symptom onset for each outcome in univariate analyses. Baseline body appreciation and intuitive eating scores remained consistent, unique predictors of a lower odds of experiencing symptom onset in multivariate models. Greater increases in intuitive eating and body appreciation over time were the two factors consistently associated with a lower odds of symptom onset across several outcomes. DISCUSSION This study provides strong evidence for the protective influence of positive body image components, intuitive eating, and self-compassion against several eating disorder symptoms. Building these factors within established prevention programs may, in the longer term, help reduce the incidence of eating disorder syndromes and symptoms.

Abstract
BACKGROUND AND AIMS The purpose of this study was to investigate the attitudes toward eating disorders in native German adolescents (Germans), adolescents with Turkish migration background in Germany (Immigrants), and native Turkish adolescents (Turks). METHOD A total of 507 adolescents (N = 139 Germans; N = 126 Immigrants; N = 242 Turks) read a vignette describing a 16-year-old female with bulimic symptoms. Participants completed questionnaires on mental health literacy, stigmatization, desirability of eating disorder-related behaviors and acquaintance with bulimic symptoms. RESULTS Adolescents living in Germany were more likely to recognize the vignette as an eating disorder than Turks. Immigrants were more similar to Germans in mental health literacy of eating disorders than Turks. However, in terms of stigmatizing attitudes, immigrants blamed more than Germans, Turks being intermediate on this variable. In Turks, higher desirability of eating disorder-related behaviors was associated with an increased acquaintance with bulimic symptoms and decreased evaluations of impairment. Higher mental health literacy was associated with less blame in Germans. CONCLUSIONS Migration background was associated with increased mental health literacy of eating disorders but did not result in reduced stigma. Differences in attitudes toward eating disorders indicate the need for differential interventions across the groups.

Abstract
Research suggests that weight-related teasing is associated with body concerns and disordered eating in male and female adolescents and women. Yet, little is known about these associations for young men with diverse racial and ethnic identities. This study examined the association of weight-related teasing frequency and distress with body concerns, loss of control (LOC) eating, dietary restraint, and history of psychiatric and medical diagnoses in racially and ethnically diverse young men. Racial and ethnic identity was examined as a potential moderator. Participants (N = 1,069; 18-30 years; Mage = 24.1 ± 3.6 years) completed an online survey and reported on general demographics; weight-related teasing; body concerns; LOC eating frequency in the last 28 days; dietary restraint; and history of psychiatric and medical diagnoses. All models adjusted for BMI, income, education, and history of psychiatric diagnoses (when not the dependent variable). Both weight-related teasing frequency and distress were significantly and positively linked with all dependent variables, and these associations did not significantly vary by racial and ethnic identity. These findings suggest that, much like in prior research with adolescents and women, experiences with weight-related teasing are associated with body concerns, disordered eating, and poorer health in racially and ethnically diverse young men, regardless of body size.

Abstract
PURPOSE This cross-sectional study examined the associations between 3rd trimester attitudes toward weight gain and (1) pre-pregnancy BMI, (2) gestational weight gain (GWG) and (3) eating behaviours assessed in the 3rd trimester. METHODS Seventy-nine (79) pregnant women completed the French version of the Pregnancy Weight Gain Attitude Scale (PWGAS), the Three-Factor Eating Questionnaire (TFEQ) and the Intuitive Eating Scale-2 (IES-2) in their 3rd trimester. Total GWG was calculated as the difference between the weight recorded before delivery and self-reported pre-pregnancy weight. RESULTS Most (55.6%) women gained weight above the Institute of Medicine's (IOM) recommendations, but there was no association between PWGAS scores and total or 3rd trimester GWG. Women with obesity had lower PWGAS total scores compared to women with overweight (3.48 ± 0.6 vs. 3.99 ± 0.3, p = 0.005), indicating more negative attitudes in women with obesity vs. overweight. Higher total PWGAS scores were positively correlated with intuitive eating scores (r = 0.28, p < 0.05), and inversely associated with unfavourable eating behaviours such as dietary restraint (r = - 0.42, p < 0.01). CONCLUSION Women with positive attitudes toward weight gain reported healthier eating behaviours in late pregnancy, which remains to be confirmed in prospective studies. Interventions addressing body image issues during pregnancy may positively influence pregnant women's health, including eating behaviours. LEVEL OF EVIDENCE Level III, case-control analytic study.

Abstract
OBJECTIVE Childhood bullying is associated with a range of adverse mental health outcomes, and here we investigated the association between bullying exposure and eating disorders (EDs). METHOD In this case-control study, we compared bullying history in individuals with EDs with community controls. Participants (n = 890, mean age = 29.50 ± 10.60) completed an online self-report battery assessing bullying history and lifetime history of bulimia nervosa (BN), binge-eating disorder (BED), and anorexia nervosa (binge-eating/purging (AN-BP) or restrictive (AN-R) subtype). Logistic regressions were performed to estimate odds ratios (ORs). RESULTS In the combined ED sample, individuals with a history of any ED were significantly more likely than controls to have experienced bullying victimization during childhood or adolescence (ORs = 1.99-3.30), particularly verbal, indirect, and digital bullying. Bullying prior to ED onset was also significantly more common than bullying within the same time frame for controls (ORs = 1.75-2.16). Further analysis showed that these effects were due to individuals with BN or BED reporting significantly more lifetime (p < .001) and premorbid bullying (p = .002) than controls, while individuals in the other diagnostic subgroups did not differ significantly from controls. DISCUSSION Our results confirm an association between bullying and binge-eating/purging ED subtypes. Prospective studies are needed to establish bullying as a risk factor for EDs.

Abstract
PURPOSE The sociocultural theory of eating disorders (EDs) posits that thin-ideal internalization may interact with social risk factors to influence ED development. Social appearance anxiety (SAA) is a potential social risk factor for EDs that may influence the relationship between thin-ideal internalization and EDs. METHODS The current study (N = 525 adolescent females) examined whether SAA moderated the relationship between thin-ideal internalization and ED symptoms cross-sectionally and prospectively across one month. RESULTS The interaction between thin-ideal internalization and SAA on ED symptoms was significant in both models, such that when SAA was higher, there was a significantly stronger relationship between thin-ideal internalization and ED symptoms. We also found that SAA uniquely, prospectively predicted ED symptoms. CONCLUSION These results suggest that adolescents with high SAA and high thin-ideal internalization are more likely to exhibit higher ED symptoms. SAA both prospectively predicts ED symptoms and may amplify the relationship between thin-ideal internalization and EDs. This research highlights SAA as a social risk factor for ED development in adolescents. Interventions focused on SAA may optimize ED prevention in this population. LEVEL OF EVIDENCE Level IV, evidence obtained from multiple time series with or without the intervention.

Abstract
The purpose of this investigation is to identify the anticipatory reward mechanisms that maintain binge eating and purging in bulimia nervosa. Emerging data indicate the importance of reward and anticipatory processes as maintenance mechanisms of bulimia nervosa that can be targeted in treatment. The proposed research will identify neurobiological and psychological anticipatory mechanisms of binge eating and purging using functional magnetic resonance imaging (fMRI), and ecological momentary assessment (EMA) in the natural environment. In this investigation, 60 adults (30 with bulimia nervosa and 30 matched comparison participants) will undergo negative and positive mood inductions followed by an fMRI food selection task (and a comparison shopping task) to examine neurobiological and affective responses to food and non-food reward anticipation. Participants with bulimia nervosa will complete two weeks of EMA examining real-time affect changes in relation to the anticipation of binge eating and purging. These methods will facilitate rigorous assessment of the links between neurobiological (fMRI) and naturalistic (EMA) data in anticipatory reward processes. Findings from this investigation will inform the conceptualization and treatment of bulimia nervosa by identifying the role of reward anticipation in symptom maintenance, providing a crucial framework for targeting these anticipatory processes in existing and novel interventions.

Abstract
PURPOSE Orthorexia is a proposed disorder that involves a pathological obsession with healthy eating. The condition has received much attention in popular media in recent years, but more empirical research is needed. Currently, orthorexia is an emerging construct with multiple proposed versions of diagnostic criteria, and there is confusion regarding the exact symptoms and pathology. This qualitative study aimed to explore the experiences of orthorexia from the perspective of recovered persons, as defined by Dunn and Bratman's 2016 criteria (Eat Behav 21:11-17, 2016). METHODS Eight participants from around the world were interviewed via Skype. These interviews were analysed using a descriptive and interpretive thematic analysis (Elliott and Timulak. A handbook of research methods for clinical and health psychology. Oxford University Press, London, pp 147-159, 2005). Informed consent was obtained from all participants. RESULTS Data analysis revealed four domains: (1) strong external influences; (2) psychological effects; (3) interpersonal functioning effects; and (4) classic eating disorder (ED) behaviours and processes. Some symptoms mirrored those seen in EDs and in obsessive compulsive disorder. CONCLUSIONS Orthorexia negatively impacted participants' physical, psychological, and social health. Additional research exploring valid and reliable screening instruments, body image, and psychological functioning would help to further understand this proposed disorder.

Abstract
This report provides a review of randomized controlled trials that tested whether an eating disorder prevention program significantly reduced future onset of eating disorders, which is important because eating disorders are common and result in marked functional impairment. We identified 15 trials involving 5080 participants (mean ages ranging from 14.5 to 22.3) that reported 19 tests of whether selective eating disorder prevention programs significantly reduced future onset of eating disorders relative to some type of minimal control condition or a credible alternative intervention. Healthy lifestyle modification prevention programs, dissonance-based prevention programs, and a self-esteem/self-efficacy prevention program significantly reduced future onset of eating disorders, though the later was only evaluated in one trial. Psychoeducational, cognitive behavioral, behavioral weight gain, interpersonal, and family-therapy-based prevention programs did not significantly reduce future onset of eating disorders. The average prevention effect size was statistically significant (OR = 1.64, 95% CI = [1.09, 2.46], t = 2.54, p = .020) and there was heterogeneity in effect sizes (Q [18] = 35.96, p = .007). Prevention effects were significantly larger for trials that recruited participants with elevations on a single risk factor versus with elevations in multiple risk factors and for healthy lifestyle modification prevention programs versus cognitive behavioral prevention programs, though the remaining examined factors did not moderate intervention effect sizes (e.g., risk of bias). The fact that lifestyle modification and dissonance-based prevention programs significantly reduced future onset of eating disorders in multiple trials, producing a 54% to 77% reduction in future eating disorder onset implies that broadly implementing these prevention programs could reduce the population prevalence of eating disorders.

Disordered Eating Behaviors Among Italian Adolescents with Type 1 Diabetes: Exploring Relationships with Parents' Eating Disorder Symptoms, Externalizing and Internalizing Behaviors, and Body Image Problems. J Clin Psychol Med Settings 2021; 27:727-745.

Abstract
The purpose of this study is to examine associations of disordered eating behaviors (DEBs) with body image problems, parents' eating disorder symptoms, and emotional and behavioral problems among adolescents with type 1 diabetes (T1D). 200 adolescents (M age = 15.24 ± 1.45 years) with T1D completed a self-report measure of DEBs and body ideal internalization, and their parents completed self-report measures of parents' eating problems and child's psychological symptoms. Seventy-three (36.5%) adolescents were DEPS-r-positive (scores ≥ 20), with higher rates among girls (χ2 = 9.034, p = .003). Adolescents with T1D and DEBs reported lower SES, worse metabolic control, higher zBMI (p < .001), more eating disorder symptoms, more body image problems, and more emotional and behavioral problems than adolescents with T1D but no DEBs (all p < .05). Parents of adolescents with DEBs showed higher levels of bulimia (p = .028) than parents of adolescents without DEBs. In both genders, pressure to conform to societal norms about body image (p < .01) and externalization symptoms (p < .05) emerged as significant predictors of DEBs. Findings suggest that adolescents with T1D and DEBs showed an alarming psychological condition, with higher level of body image and more emotional and behavioral problems.

Abstract
OBJECTIVE Shame is broadly implicated in the development and maintenance of eating pathology. However, the relationship between shame and binge eating symptoms specifically is less clear. This review aimed to clarify what types of shame are associated with binge eating symptoms and the antecedents and maintenance factors in these relationships. METHOD A systematic search for quantitative and qualitative empirical studies was conducted to identify evidence of the relationship between shame and binge eating symptoms. Altogether, 270 articles were identified and screened for eligibility in the review. RESULTS Results of the relevant empirical studies (n = 31) identified several types of shame associated with binge eating pathology: (i) internal shame, (ii) external shame, (iii) body shame and (iv) binge eating-related shame, as well as several mechanisms and pathways through which shame was associated with binge eating symptoms. DISCUSSION Drawing from the research findings, this review presents an original, integrated model of the cyclical shame-binge eating relationship. Clinical interventions that might break this cycle are discussed, as well as methodological weaknesses which limit causal inferences and important areas of future research.

Abstract
OBJECTIVE Due to high prevalence, female athletes are considered a high-risk group for eating disorders (i.e., clinical ED = 2.0% to 19.9%; subclinical ED = 7.1% to 49.2%). Cross-sectional and longitudinal research have identified psychosocial factors that influence current and future disordered eating (e.g., appearance pressures, body satisfaction), but are limited in design (e.g., timeframe, active competitors). Quantitative evaluations of psychosocial predictors of female athletes' disordered eating in retirement are lacking. METHOD The current study investigated the predictive ability of psychosocial risk factors (e.g., body dissatisfaction, negative affect) from Time1, when collegiate female athletes were actively competing, to Time2, 6 years later when the women were retired (N = 194; Mage = 25.75 years [SD = 1.19]). RESULTS From Time1 to Time2, 23.5% of the women who were Healthy moved to the Disordered classification; 51% remained in Disordered. The full model for athletes who maintained their Disordered status correctly classified 76% of the athletes. Dietary intent, pressure to exercise and change appearance, body satisfaction, and internalization significantly predicted athletes' maintenance as Disordered. DISCUSSION Early intervention efforts that address appearance pressures, body image, and healthful eating when athletes are actively competing are vital to help alleviate future distress, particularly in retirement.

Abstract
PURPOSE The many studies examining the relationship between anorexia nervosa (AN) and personality abnormalities have observed high comorbidity. However, no definitive studies to date have established whether there is a causal connection or whether it is a complication. The current study aimed to explore the nature of the relationship between personality disorder (PD) traits, obsessionality and perfectionism, using a study design that allows the testing of some comorbidity models. METHODS Twenty-nine women were recruited from a group of former AN patients treated during their adolescence in a specialized unit around 20 years before the time of this study. They were divided into two groups according to the current presence of eating disorder (ED) symptoms (current-ED, n = 11; recovered, n = 18). Both groups were compared to a matched control group (n = 29) regarding current PD traits, obsessive beliefs and perfectionism. RESULTS Borderline PD traits, most cluster C PD traits and overestimation of threat were more common in the current-ED group than in the control and recovered groups. Obsessive-compulsive PD traits, intolerance of uncertainty, and perfectionism were also significantly more prevalent in the current-ED group compared to controls but did not reach significance when compared to the recovered group. No significant differences were found between the recovered and control groups. CONCLUSION Our results mostly support the personality abnormalities observed as a transient effect related to the presence of ED psychopathology in patients with adolescent-onset AN. LEVEL OF EVIDENCE Level III, case-control analytic studies.

Abstract
This study aimed to (1) examine the unique role of mindfulness and self-compassion on eating disorder (ED) psychopathology and functional impairment, and (2) compare levels of mindfulness and self-compassion between health controls and individuals categorized with bulimia nervosa (BN), and binge-eating disorder (BED). Data were analyzed from 1101 community-based participants, of which 145 met criteria for BN, 150 for BED, and 286 for healthy controls. Results from a series of multiple regressions revealed that self-compassion accounted for substantially more variance in ED psychopathology and functional impairment than mindfulness in the total sample and across the three subgroups, at times explaining 20 times more variance than mindfulness. Results remained unchanged when excluding the mindfulness subscale from the Self-Compassion Scale. When comparing these variables across the three study groups, results showed that self-compassion and mindfulness levels were lowest in the BN group, followed by the BED group, and then the healthy control group. Findings overall suggest that non-judgmental awareness may be less important in explaining levels of ED psychopathology than the nature of one's interaction with emotionally charged, negative experiences. Findings also point to possible priority intervention targets in indicated prevention and treatment programs.

Abstract
Drunkorexia is characterized by a group of behaviors designed to minimize caloric intake while maximizing levels of alcohol intoxication. Individuals plan and modify their diet, via skipping meals, exercising, or purging, to save calories for a night of alcohol consumption. Minimal research has examined risk factors related to drunkorexia, and little is known regarding associated problems. We used structural equation modeling to test associations between coping and enhancement motives, drive for thinness, body dissatisfaction, and disordered eating (i.e., bulimia behaviors) and drinking among an at-risk college population (N = 364). Drive for thinness and alcohol coping motives were positively associated with drunkorexia. Notably, drunkorexia was associated with alcohol-related outcomes, but not bulimia. While common risk factors are shared with eating pathology, drunkorexia appears to be a unique construct apart from bulimia behaviors. Results indicate drunkorexia behaviors may extend past normative drinking and place individuals at increased risk of alcohol-related problems. The current study contributes to greater understanding of functional models and maladaptive outcomes related to drunkorexia behaviors.

Abstract
Abstract. Eating disorders are a major health concern and the identification of relevant risk factors is crucial for prevention. This meta-analysis aims to give insight into the relevance of low self-esteem in the development of pathological eating. Longitudinal and partial correlations were synthesized in a random-effects multilevel model. In total, 25 effect sizes were obtained from 13 primary studies. These mainly included females from late childhood to young adulthood. The results reveal a practically relevant effect of self-esteem on eating disorders ( r = −.23, ρ = −.09). This effect was significantly larger for females and for shorter time periods between measurements. Additionally, self-esteem and eating disorders are both temporally stable. It is concluded that low self-esteem acts as a universal risk factor for different eating disorders. Limitations are due to the reliance on bivariate correlations and a small number of effect sizes. The necessity of more high-quality research in this field is discussed.

Abstract
Gender is a relevant factor in the etiology of eating disorders (ED) as evidenced by gender-specific components of disordered eating and by the high risk of ED among transgender individuals, in addition to other factors. However, research on connections between ED and gender identity are limited. Researchers who produce explanatory models, content themselves with faulting the sociocultural ideal of slimness for women, but they fail to grasp the connection between culture, gender and the body and they fall short of integrating this perspective into existing psychological knowledge about ED. Psychological research informed by feminist theory has begun to bridge this gap, but this growing area of research needs to be further developed and should include an understanding of ED in persons with all gender identities. This article expands the discussion of gender and ED, by grounding ED in an understanding of gender itself and by discussing methodological implications of this understanding.

Abstract
Several studies have identified risk factors that predict future onset of eating disorders (ED) in adolescence, however, it is currently unknown how specific ED symptom dynamics operate both across time and within individuals. Advances in network methodologies allow for the study of how dynamic symptoms interrelate and predict each other within-persons and across time. In the current study, we used longitudinal group-level (N = 1272) (addressing symptom interrelations across people and across time; between-subjects, contemporaneous, and temporal networks) and intra-individual (symptom interrelations within each person and across time; contemporaneous and temporal networks) network analyses (subset n = 50) in prospective 48-month interview data in at-risk adolescents and young adults. We computed between-subject networks (how symptoms are associated on average, for group sample only), contemporaneous networks (how symptoms are associated at one time point, accounting for previous time points), and temporal networks (examining how symptoms predict each other across time). We replicated prior network results which suggest that overvaluation of weight and shape are central in at-risk adolescents and young adults. We found that individual networks (n = 1 networks) were highly variable across individuals. Overall, our results show how both group-level and longitudinal intra-individual network analysis can inform our understanding of how EDs develop in adolescence and point to the importance of conceptualizing development on an individual level of analysis.

Abstract
Although researchers have examined eating disorders in female athletes, few such studies have been done with athletes who are retired, and even fewer have been quantitative. Thus, the authors empirically tested an established eating disorder theoretical model with 218 former NCAA Division-I female collegiate athletes who had been retired for 2-6 years. In retirement, participants completed measures of general sociocultural pressures related to body and appearance, thin-ideal internalization, body dissatisfaction, dietary restraint, negative affect, and bulimic symptomatology. Through structural equation modeling, the authors examined the direct and indirect relationships among the latent variables while controlling for body mass index and years since retirement. The model fit the data well, supporting the hypothesized direct and indirect relationships among the variables and explaining 54% of the variance in bulimic symptomatology. Despite no longer being exposed to sport pressures that contribute to eating disorders, female athletes experience such symptoms long into retirement.

Abstract
BACKGROUND Compared to males, female adolescents show greater concerns about their appearance, concerns related to their self-esteem. We explored the associations between self-esteem, body image and BMI as proxies for appearance, and eating-disordered behavior among adolescent females. METHODS A total of 263 females (mean age:15.78 years) took part in this study. They completed questionnaires covering anthropometric characteristics, self-esteem, eating-disordered behavior, subjective physical activity levels, and body image. RESULTS Higher scores for self-esteem were associated with higher scores for eating-disordered behavior, indices of physical activity, and slimmer body image. Body image was not associated with eating-disordered behavior. Multiple regression analyses showed that self-esteem, but not physical activity, or body image predicted eating-disordered behavior. CONCLUSIONS Among a non-clinical sample of female adolescents, self-esteem and eating-disordered behavior were positively associated. Body image was associated in a complex and contradictory fashion. It is possible that cognitive-emotional mastering of the vital impulse to eat may enhance self-esteem.

Abstract
PURPOSE Risk factors of negative affect, body dissatisfaction, distress tolerance, and negative urgency are independently associated with bulimia symptoms and non-suicidal self-injury (NSSI). However, relationships of these risk factors within comorbid presentations are not fully understood. The current study examined specific roles of these risk factors within this relationship. METHODS An at-risk community sample of young adults (N = 429) completed an online survey of negative affect, body dissatisfaction, distress tolerance, negative urgency, bulimia symptoms, and NSSI. RESULTS A hypothesized path model was a good fit to the data. Results indicated direct paths from body dissatisfaction, negative urgency, and distress tolerance to bulimia symptoms. Negative urgency, distress tolerance, and bulimia symptoms were directly associated with NSSI. Consistent with hypotheses, distress tolerance and negative urgency acted as vulnerability factors, increasing the strength of associations between bulimia symptoms and NSSI. Distress tolerance also strengthened associations between negative urgency and NSSI. In addition to the direct effect, negative urgency was indirectly associated with NSSI via body dissatisfaction bulimia. Hypothesized indirect effects through distress tolerance were not supported. CONCLUSIONS Results support etiological models of bulimia and NSSI, and suggest deficits in emotion regulation strengthen risk of comorbid presentations. Furthermore, individuals with greater impulsivity and difficulty tolerating distress are at increased risk of engaging in both bulimia behaviors and NSSI, providing targets for clinical intervention.
