A comparison of eating disorder psychopathology, appearance satisfaction, and self-esteem in overweight and obese women with and without binge eating

Global self-esteem and degree of overweight/obesity: are they linked in the adult population? A systematic review and meta-analysis

OBJECTIVE

Self-esteem may be adversely affected in adults with overweight or obesity, particularly women and those showing higher BMIs, although there is no consensus in the literature. The objective of the current study, based on reported cross-sectional associations, was to clarify the relationship between global self-esteem and overweight/obesity in adults.

METHODS

Four databases were searched to identify eligible literature published prior to June 2024, and a systematic review was conducted of the 120 articles identified. Meta-analytic processing of 38 eligible articles at the study level and of the participant data obtained from 16 studies (n = 2,972) was conducted for quantitative synthesis. Potential moderators, such as gender, age, BMI, type of assessment, and treatment-seeking status, were tested.

RESULTS

The summary correlation between BMI and self-esteem across studies was r = -0.11, 95% CI [-0.17, -0.05], z = -3.70, p < .001. None of the tested moderators affected this association, although the meta-analysis of the individual participant data provided by the authors revealed a small effect of gender and a non-linear evolution of self-esteem linked to BMI.

CONCLUSION

The present study found a negative relationship between global self-esteem and overweight/obesity in adults, which suggests a negative, although weak, effect of excess weight on self-perception.

Overvaluation of weight and shape in obesity: a comparative study between people with and without binge eating disorder

Introduction

The overvaluation of weight and shape is a diagnostic criterion in eating disorders, except in binge eating disorder (BED), where it has received less attention. This aspect is also not usually analyzed in people with overweight or obesity without an eating disorder. This research aims to identify the indicators of symptomatology, as well as those of self-construction and cognitive structure, that are associated with overvaluation in obesity, either alone or in conjunction with BED.

Method

A sample of 102 overweight or obese participants was accessed. The sample was divided into four groups: one without overvaluation or BED (n = 33); a second with overvaluation and without BED (n = 21); a third with BED, but without overvaluation (n = 15), and a fourth with BED and overvaluation (n = 33). The groups completed instruments regarding eating symptomatology, anxiety, depression, and stress. In addition, they were administered the Repertory Grid Technique, a semi-structured interview to evaluate the cognitive structure involved in the construal of the self and others.

Results

The factors of overvaluation and the presence of BED independently explained eating symptomatology, and the latter also showed a tendency to influence anxiety, depression, and stress. In terms of cognitive structure, weight polarization was explained by overvaluation, while BED was associated with a high presence of cognitive conflicts. In self-construction, BED was the factor that explained the differences, particularly in Self-Ideal discrepancy.

Discussion

The results highlight the importance of overvaluation in obesity, even in the absence of BED. Its evaluation and treatment are recommended. Furthermore, in the case of BED, it is also advisable to evaluate the overvaluation of weight and shape since it can be a severity specifier.

A factor that can yield to eating attitude disorders in university students: Self-esteem

OBJECTIVE

To determine prevalence of eating attitude disorder (EAD) and the effect of self-esteem on EAD in female university students.

Study Design: In this cross-sectional study, female university students were included. The dependent variable was EAD determined by Eating Attitude Test-40. Socio-demographic characteristics, body perception, obesity, self-compassion and self-esteem were independent variables. Logistic regression (LR) models have been established to determine the associated factors of EAD. p < 0.05 was considered significant.

Results: EAD were found in 3.3% (n = 20) of the participants (n = 600). 44.5% had low and medium self-esteem and %13.4 were overweight (body mass index (BMI) ≥ 25.0). According to LR models, after adjusted for age, increased self-esteem score (decreased self-esteem) (OR:1.8, 95%CI:1.063-3.303) and practicing popular diet (OR:12.6, 95%CI:4.439-35.904) increased the risk of EAD significantly.

Conclusion: EAD were less than expected in this group of university students. Self-esteem is an important factor affecting EAD. Students with EAD may be recommended to get psychological support as well as nutritional counseling.

Self-esteem and weight status of young adults: Findings from a pilot study

BACKGROUND

Researchers have examined the association between self-esteem and obesity in past studies. However, most studies have focused on pediatric or adolescent populations. In this pilot study, we aim to explore the association of self-esteem with weight status in young adults, a group of individuals in a significant and pivotal period of their lives whose needs and challenges have received little attention in previous studies.

MATERIALS AND METHODS

Exactly 127 college juniors and seniors in the Midwest participated in late 2017. For our survey, we collected the following information: body weight, height, self-esteem score from the state self-esteem scale, grade point average, risk of eating disorders, sleep quality, nutritional behavior, lifestyle (smoking, frequency of exercise, alcohol drinking, average daily time watching television, playing video games, and social media use), and demographic and socioeconomic background. We used logistic regression for our analysis.

RESULTS

The logistic regression indicates that a one-point increase in the self-esteem score was negatively associated with a young adult's odds of having an unhealthy weight (being overweight or obese) by approximately 3%. Furthermore, soda drinking is a statistically significant factor associated with weight status.

CONCLUSIONS

This finding suggests self-esteem is positively associated with a healthy weight in young adults. A larger-scale study should be conducted in the future to validate this relationship and better understand young adults' needs.

Modified Dual Pathway Model for Binge Eating: The Role of Emotion Dysregulation

We tested a modification of the dual pathway model using two sequential mediators between body dissatisfaction and binge eating: restricted eating and difficulties in emotion regulation replacing negative affect. A total of 435 college students completed an online survey. Results from path analyses indicated that the relationship between body dissatisfaction and binge eating was not mediated by restricted eating for neither women nor men. However, this relationship was mediated first by restricted eating and then by difficulties in emotion regulation for women only. Moreover, this relationship was mediated by difficulties in emotion regulation for both women and men. A post hoc analysis indicated that the above mediation results were still significant after adding negative affect into the model. No mediations through negative affect were significant. Clinical implications include the conceptualization and intervention of eating concerns within an emotion dysregulation framework.

Disordered eating through the lens of positive psychology: The role of embodiment, self-esteem and identity coherence

Applying a positive psychology perspective, this study aimed to identify potential intra-individual factors that might protect against the development of disordered eating in a community sample of young women and men (N = 510; 56 % women; M_age = 24.3). Based on existing literature, the study included the general resilience factors of self-esteem and identity coherence as well as two dimensions of positive embodiment (positive body connection and comfort, and agency and functionality). All factors were negatively correlated with disordered eating among women and men. Hierarchical regression analyses indicated that positive embodiment, specifically positive body connection, was a significant predictor of lower degrees of disordered eating symptoms in both women and men, followed by self-esteem. The overall prediction model accounted for 42.6 % in the variation of disordered eating symptoms for women and 23.9 % for men. Prevention and treatment interventions promoting health factors that protect against the development of eating disorders are much needed. The present study informs such efforts by emphasizing the promotion of positive embodiment.

Binge eating behavior in a sample of Lebanese Adolescents: Correlates and Binge Eating Scale validation

BACKGROUND

Binge eating disorder is a common eating disorder among the adolescent population. The available literature in the Middle East in general, and Lebanon specifically, is relatively scarce and/or outdated. The objectives of this study were to (1) validate the Binge Eating Scale (BES) for use in Lebanese adolescents, and (2) assess correlates of binge eating behavior among this population.

METHODS

A cross-sectional study conducted between May and June 2020, enrolling 555 adolescents between the ages of 15-18 years old from all Lebanese governorates. The Binge Eating Scale was used to screen for the presence/absence of binge eating.

RESULTS

A confirmatory factor analysis revealed that the one-factorial model fits the data best. The results of a linear regression, taking the binge eating score as the dependent variable, showed that higher body dissatisfaction, more alcohol use disorder, higher depression, vomiting to lose weight and starving to lose weight were significantly associated with more binge eating. Higher self-esteem was significantly associated with less binge eating.

CONCLUSION

The Arabic Version of the BES scale seems to be a reliable tool to be used in Lebanese adolescents for the assessment of binge eating. More body dissatisfaction, lower self-esteem, increased depressive symptoms were associated with more binge eating. We hope this tool will be a reliable one to be used in epidemiological studies and research about eating behaviors/disorders. The results showed that higher body dissatisfaction, higher depression, vomiting to lose weight and starving to lose weight were significantly associated with more binge eating. Our study also showed that the Binge Eating Scale is an adapted and validated tool to be used among Lebanese adolescents for the assessment of binge eating. We hope that the study results will help clinicians in the screening and management of Binge Eating behaviors among Lebanese adolescents.

Impulsivity and compulsivity in binge eating disorder: A systematic review of behavioral studies

BACKGROUND

Binge eating disorder (BED) often includes impulsive and compulsive behaviors related to eating behavior and food. Impulsivity and compulsivity generally may contribute to the etiology and maintenance of multiple psychiatric disorders including BED. This review aimed to identify and synthesize available behavioral studies of impulsivity and compulsivity among individuals with BED.

METHOD

A systematic search was performed focusing on BED and specific facets of impulsivity (rapid response and choice) and compulsivity (set-shifting, cognitive flexibility, and/or habit learning). All case-control studies comparing adults with either full-threshold or subthreshold BED to individuals with normal weight, overweight/obesity, or other eating disorders (e.g., bulimia nervosa) were included.

RESULTS

Thirty-two studies representing 29 unique samples met inclusion criteria. Increased choice impulsivity was observed among individuals with BED relative to individuals with normal weight. There were mixed findings and/or a lack of available evidence regarding rapid response impulsivity and compulsivity. The presence of between-group differences was not dependent on sample characteristics (e.g., full or sub threshold BED diagnosis, or treatment-seeking status). Heterogeneity relating to covariates, task methodologies, and power limited conclusions.

CONCLUSIONS

Literature supports a postive association between choice impulsivity and BED. More research is needed to determine if individuals with BED demonstrate elevated levels of either rapid response impulsivity or types of compulsivity. Careful selection of covariates and consideration of task methodologies and power would aid future research.

Relationships Between Self-Esteem, Interoceptive Awareness, Impulse Regulation, and Binge Eating. Path Analysis in Bariatric Surgery Candidates

OBJECTIVE

The current study investigates the hypothesis that the effect of low self-esteem on binge eating in bariatric candidates was mediated by both difficulties in the perception of bodily signals and impulse regulation after accounting for gender, age, and body mass index.

METHOD

59 preoperative patients (both male and female) were screened by means of self-report measures of self-esteem, interoceptive deficits, impulse dysregulation, and severity of binge eating. Results: Results indicated that all direct effects were significant, except for the self-esteem on impulse dysregulation and the interoceptive deficits on binge eating. Self-esteem had a significant indirect effect on impulse dysregulation mediated by interoceptive deficits. Impulse dysregulation, in turn, mediates the effect of interoceptive deficits on binge eating. Moreover, the path starting from self-esteem, going first to interoceptive deficits, then going via impulse regulation difficulties to binge eating was significant.

RESULTS AND CONCLUSIONS

A potential underlying mechanism through which self-esteem is linked to binge eating has been suggested. Obese individuals who perceived themselves as inadequate may carry a stronger burden by the confusion and mistrust related to bodily functioning and, consequently, may act more impulsively, through binge eating.

Disordered Eating Among Individuals with Excess Weight: a Review of Recent Research

PURPOSE OF REVIEW

The purpose of this review was to examine different forms of disordered eating among individuals with excess weight, including their rates, correlates, and psychosocial treatments.

RECENT FINDINGS

Binge eating/binge eating disorder, loss of control eating, emotional eating, and food addiction are all fairly prevalent among individuals with excess weight. They appear to share many of the same correlates, including broader eating disorder psychopathology, body/shape/weight concerns, depression, anxiety, and low self-esteem. Behavioral, cognitive-behavioral, and third-wave (e.g., acceptance, mindfulness) therapies appear effective in improving binge eating, loss of control eating, emotional eating, associated features (e.g., weight and shape concerns), and psychological distress (e.g., depression). Certain forms of disordered eating are elevated among individuals with excess weight, and psychosocial interventions have been found effective in improving symptomatology. Empirical research examining the efficacy of treatments for food addiction is lacking, and greatly needed given both its rate and controversy.

An update on obesity: Mental consequences and psychological interventions

Besides physical consequences, obesity has negative psychological effects, thereby lowering human life quality. Major psychological consequences of this disorder includes depression, impaired body image, low self-esteem, eating disorders, stress and poor quality of life, which are correlated with age and gender. Physical interventions, mainly diet control and energy balance, have been widely applied to treat obesity; and some psychological interventions including behavioral therapy, cognitive behavioral therapy and hypnotherapy have showed some effects on obesity treatment. Other psychological therapies, such as relaxation and psychodynamic therapies, are paid less attention. This review aims to update scientific evidence regarding the mental consequences and psychological interventions for obesity.

The self and eating disorders

In our review, we focus on self-related constructs in the context of eating disorders with four aims. First, we examine a variety of self-related constructs that have been theoretically and empirically linked to the development and course of eating disorders. In addition to the more well-researched constructs of self-esteem and self-efficacy, we also report on findings related to selflessness, contingent self-worth, self-objectification, ego-syntonicity, self-concept clarity, self-compassion, social comparison, self-oriented perfectionism/self-criticism, and narcissism. Second, we discuss self-related constructs that may be especially relevant to comorbidities common among those with eating disorders. Third, we review intervention and prevention programs where self-related constructs play a prominent role. Lastly, we share future research directions regarding self-related constructs and eating disorders that we believe will advance a deeper understanding of the role of the self in the eating disorders.

Improving prediction of eating-related behavioral outcomes with zero-sensitive regression models

Objective

Outcome variables gauging the frequency of specific disordered eating behaviors (e.g., binge eating, vomiting) are common in the study of eating and health behaviors. The nature of such data presents several analytical challenges, which may be best addressed through the application of underutilized statistical approaches. The current study examined several approaches to predicting count-based behaviors, including zero-sensitive (i.e., zero-inflated and hurdle) regression models.

Method

Exploration of alternative models to predict eating-related behaviors occurred in two parts. In Part 1, participants (N = 524; 54% female) completed the Eating Disorder Examination-Questionnaire and Daily Stress Inventory. We considered the theoretical basis and practical utility of several alternative approaches for predicting the frequency of binge eating and compensatory behaviors, including ordinary least squares (OLS), logistic, Poisson, negative binomial, and zero-sensitive models. In Part 2, we completed Monte Carlo simulations comparing negative binomial, zero-inflated negative binomial, and negative binomial hurdle models to further explore when these models are most useful.

Results

Traditional OLS regression models were generally a poor fit for the data structure. Zero-sensitive models, which are not limited to traditional distribution assumptions, were preferable for predicting count-based outcomes. In the data presented, zero-sensitive models were useful in modeling behaviors that were relatively rare (laxative use and vomiting, 9.7% endorsed) along with those that were somewhat common (binge eating, 33.4% endorsed; driven exercise, 40.7% endorsed). Simulations indicated missing data, sample size, and the number of zeros may impact model fit.

Discussion

Zero-sensitive approaches hold promise for answering key questions about the presence and frequency of common eating-related behaviors and improving the specificity of relevant statistical models. Hurdle models may also be appropriate when theoretically justified.

Altered Processing and Integration of Multisensory Bodily Representations and Signals in Eating Disorders: A Possible Path Toward the Understanding of Their Underlying Causes

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM V) eating problems are the clinical core of eating disorders (EDs). However, the importance of shape and weight overvaluation symptoms in these disorders underlines the critical role of the experience of the body in the etiology of EDs. This article suggests that the transdiagnostic centrality of these symptoms in individuals with EDs may reflect a deficit in the processing and integration of multisensory bodily representations and signals. Multisensory body integration is a critical cognitive and perceptual process, allowing the individual to protect and extend her/his boundaries at both the homeostatic and psychological levels. To achieve this goal the brain integrates sensory data arriving from real-time multiple sensory modalities and internal bodily information with predictions made using the stored information about the body from conceptual, perceptual, and episodic memory. In this view the emotional, visual, tactile, proprioceptive and interoceptive deficits reported by many authors in individuals with EDs may reflect a broader impairment in multisensory body integration that affects the individual's abilities: (a) to identify the relevant interoceptive signals that predict potential pleasant (or aversive) consequences; and (b) to modify/correct the autobiographical allocentric (observer view) memories of body related events (self-objectified memories). Based on this view, the article also proposes a strategy, based on new technologies (i.e., virtual reality and brain/body stimulation), for using crossmodal associations to reactivate and correct the multisensory body integration processes.

Emotional eating and cognitive conflicts as predictors of binge eating disorder in patients with obesity

Background/Objectives: Binge Eating Disorder (BED) is often associated with obesity. In order to identify the variables that allow to better detect the presence of BED, people with overnutrition were compared with and without BED in the presence of cognitive conflicts, eating symptoms and anxious-depressive symptoms. The inclusion of cognitive conflicts had been relevant in bulimia studies but had not been investigated with respect to BED. Method: Two groups with obesity were evaluated, one without BED (OB, n = 54) and the other with BED (OB-BED, n = 48), using a social-demographic questionnaire as well as a semi-structured interview to assess BED, questionnaires (DASS-21, EDE-Q, EEQ) and the Repertory Grid Technique. Results: Overall, the OB-BED group presented more conflicts and more symptoms. The model that best differentiated between the groups included emotional eating and level of cognitive conflicts, correctly classifying 91.4% of the sample. Conclusion: These results highlight the role played by cognitive conflicts and emotional eating as differentiating elements between OB and OB-BED, with a high level of predictive accuracy.

The critical role of cognitive-based trait differences in transcranial direct current stimulation (tDCS) suppression of food craving and eating in frank obesity

Obesity remains a major public health concern and novel treatments are needed. Transcranial direct current stimulation (tDCS) is a neuromodulation technique shown to reduce food craving and consumption, especially when targeting the dorsolateral prefrontal cortex (DLPFC) with a right anode/left cathode electrode montage. Despite the implications to treat frank (non-bingeeating) obesity, no study has tested the right anode/left cathode montage in this population. Additionally, most tDCS appetite studies have not controlled for differences in traits under DLPFC control that may influence how well one responds to tDCS. Hence, N = 18 (10F/8M) adults with frank obesity completed the Dutch Eating Behavior Questionnaire-Restraint and Barratt Impulsiveness Scale, and received 20 min of 2 mA active tDCS and control tDCS session. Craving and eating was assessed at both sessions with a food photo "wanting" test and in-lab measures of total, preferred, and less-preferred kilocalories consumed of three highly palatable snack foods. While main effects of tDCS vs. control were not found, significant differences emerged when trait scores were controlled. tDCS reduced food craving in females with lower attention-type impulsiveness (p = 0.047), reduced preferred-food consumption in males with lower intent to restrict calories (p = 0.024), and reduced total food consumption in males with higher non-planning-type impulsiveness (p = 0.009) compared to control tDCS. This is the first study to find significant reductions in food craving and consumption in a sample with frank obesity using the most popular tDCS montage in appetite studies. The results also highlight the cognitive-based heterogeneity of individuals with obesity and the importance of considering these differences when evaluating the efficacy of DLPFC-targeted tDCS in future studies aimed at treating obesity.

The role of coherence of mind and reflective functioning in understanding binge-eating disorder and co-morbid overweight

Coherence of mind and reflective functioning may impact negative affect and interpersonal functioning over and above the effects of symptoms of depression and interpersonal problems that contribute to symptoms of binge-eating disorder (BED) and overweight/obesity. Matched samples of overweight women with BED and overweight and normal weight women without BED completed the Adult Attachment Interview, a measure of depressive symptoms, and a measure of interpersonal problems. Greater symptoms of depression distinguished women with BED from the matched comparison samples. Greater interpersonal problems differentiated women with BED from overweight women without BED. Coherence of Mind scores did not differentiate the samples. However, lower Reflective Functioning scores did distinguish both women with BED and overweight women without BED from normal weight women. Lower reflective functioning may lead to binge eating independent of depressive symptoms and interpersonal problems.

A Conceptual Framework for the Expansion of Behavioral Interventions for Youth Obesity: A Family-Based Mindful Eating Approach

BACKGROUND

Currently, over 30% of US youth are overweight and 1 in 6 have metabolic syndrome, making youth obesity one of the major global health challenges of the 21st century. Few enduring treatment strategies have been identified in youth populations, and the majority of standard weight loss programs fail to adequately address the impact of psychological factors on eating behavior and the beneficial contribution of parental involvement in youth behavior change.

METHODS

A critical need exists to expand treatment development efforts beyond traditional education and cognitive-behavioral programs and explore alternative treatment models for youth obesity. Meditation-based mindful eating programs represent a unique and novel scientific approach to the current youth obesity epidemic given that they address key psychological variables affecting weight.

RESULTS

The recent expansion of mindfulness programs to include family relationships shows the immense potential for broadening the customarily individual focus of this intervention to include contextual factors thought to influence youth health outcomes.

CONCLUSIONS

This article provides an overview of how both mindful eating and family systems theory fits within a conceptual framework in order to guide development of a comprehensive family-based mindful eating program for overweight youth.
