Tang YT, Liew JX, Chooi WT. Characteristics of Malaysian 16-year-old girls who reported regular binge eating episodes and the associated risk factors: a descriptive study. Int J Adolesc Med Health 2023; 35:411-422. [PMID: 37712612 DOI: 10.1515/ijamh-2023-0064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Accepted: 08/26/2023] [Indexed: 09/16/2023]
Abstract
OBJECTIVES Adolescents may suffer from binge eating (BE), that refers to consuming a large amount of food in a short period of time and accompanied by feelings of loss of control (LOC) over eating. This study compared the prevalence of BE between 16-year-old Malaysian girls from two types of public schools, Malay-English-medium and Chinese-Malay-English-medium schools. Additionally, this study identified associated risk factors of those who presented regular BE episodes, including LOC eating, anxiety, body mass index (BMI), body dissatisfaction (BD) and eating disorders (EDs) psychopathology. METHODS 398 participants completed self-reports assessing BE symptoms, LOC eating, state anxiety, trait anxiety, EDs psychopathology, and BD. They also reported heights and weights. Descriptive statistics, t-tests, chi-square tests, and Z-test for independent proportions were conducted. RESULTS There was no significant difference in either the prevalence of BE or EDs psychopathology between participants from the two types of schools. 71 (17.8 %) participants reported moderate-to-severe symptoms of BE, and 46 (11.6 %) reported moderate-to-severe levels of LOC eating. Those who reported moderate-to-severe symptoms of BE reported significantly higher levels of LOC eating, BD, drive to be thinner, BMI, state anxiety, and EDs psychopathology, compared to those who reported none-to-minimal BE. CONCLUSIONS BE and LOC eating appeared to be relatively common among secondary school girls in Malaysia. The relatively high prevalence of BE amongst adolescents in our sample highlighted the importance of early identification of signs for BE as preventive measures from developing EDs psychopathology among children and adolescents. We propose that attitudes towards eating and body image-related concerns should be included in school screenings aimed at preventing psychological problems in minors.

Abstract
Favorable diets often include restrictive practices that have proven health benefits, even if initiated later in life. The aim of this qualitative study is to gain a comprehensive understanding of Restrictive Dietary Practices (RDPs) among a sample of middle-aged and older German adults (aged 59-78 years). We conducted 24 narrative in-depth interviews and analyzed the data using qualitative content analysis (Kuckartz). Following an inductive thematic approach, a typology was reconstructed comprising four typical RDP characteristics: I. The Holistically Restraining Type, II. The Dissonant-savoring Restraining Type, III. The Reactively Restraining Type, and IV. The Unintentionally Restraining Type. These types differed regarding the practical implementation of, e.g., restrictive food choice into everyday routines, barriers to do so, as well as with respect to attitudes and motives underlying RDPs. The major motives for adopting a RDP involved health, well-being, ethical, and ecological concerns. The most prominent barriers to a 'successful' adoption of RDPs were the enjoyment of food and the desire for spontaneity and freedom of (food) choice. Our study offers an in-depth understanding of the aspects that shape the widespread practice of dietary restriction among middle-aged and older adults. Lifeworld-related changes in RDPs and possible 'type shiftings' are discussed as well as the meaning and chances of RDPs for public health promotion.

Fasting in mood disorders and its potential therapeutic aspects -narrative review. CURRENT PROBLEMS OF PSYCHIATRY 2022.

Abstract
Abstract
Introduction: Fasting is defined as a period of voluntary abstinence from eating food for religious, therapeutic or political reasons, which is associated with a reduction in the supply of sources (kilocalories) to the body. There are different types of fasting, including short, long or intermittent fasting. It has been shown that the use of different types of fasting can influence the occurrence of mood disorders. The aim of this review was to search for the relationship between the use of fasting and mood disorders and its potential use as a therapeutic method.
Material and method: The available literature was reviewed by searching the PubMed and Google Scholar databases using the following keywords: fasting, intermittent fasting, mood disorders, depression, Ramadan, for studies listed from database inception to November 2021.
Results: A review of the collected scientific articles indicates that the dietary restrictions, including both daily restriction of caloric consumption and the use of intermittent fasting (IF), has potentially numerous health benefits in the co-treatment of mental diseases. However, due to conflicting results, further clinical trials in mentally ill people should be conducted. It is worth remembering that among patients with mental illnesses there are somatically ill. IF in these people may require additional nutritional modifications or discontinuation of therapy.
Conclusions: Dietary restriction and fasting are promising methods in co-therapy of mood disorders treatment. However, implementing therapy needs earlier individual evaluation of their benefits and risk, the same as patient’s feasibility of implementing this type of intervention.

Abstract
OBJECTIVE Parental bonding, low self-esteem, emotion dysregulation, and eating style are correlated with each other and are associated with binge eating among adolescents. However, no studies have yet examined all these variables simultaneously. In the current study, the independent and combined influences of such constructs on binge eating were tested with structural equation modeling. METHOD A sample of 973 students aged between 12 and 16 (M = 14.17, SD = 1.25) years was screened by means of self-report measures assessing parental bonding, self-esteem, emotion dysregulation, eating styles and binge eating severity. RESULTS Self-esteem (β = -0.205) and eating styles (emotional β = 0.313, external β = 0.133, and restrained β = 0.178) had a direct effect on binge eating severity. The model (χ2(22) = 57.679; RMSEA = 0.041; CFI = 0.987; TLI = 0.949; SRMR = 0.024) revealed that the paths from both maternal and paternal care and maternal overprotection to binge eating were mediated through low self-esteem, emotion dysregulation and each eating style, explaining 35% of the variance. DISCUSSION Findings provide support for a comprehensive theoretical-based model of risk factors for binge eating and suggest the possible mechanisms through which the quality of early parental relationships contribute to developing dysfunctional eating patterns. Treatment and prevention efforts should improve self-esteem and emphasize emotion regulation capabilities.

Sleep dysregulation in binge eating disorder and "food addiction": the orexin (hypocretin) system as a potential neurobiological link. Neuropsychopharmacology 2021; 46:2051-2061. [PMID: 34145404 PMCID: PMC8505614 DOI: 10.1038/s41386-021-01052-z] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 05/26/2021] [Accepted: 05/28/2021] [Indexed: 12/12/2022]
Abstract
It has been proposed that binge eating reflects a pathological compulsion driven by the "addictive" properties of foods. Proponents of this argument highlight the large degree of phenomenological and diagnostic overlap between binge eating disorder (BED) and substance use disorders (SUDs), including loss of control over how much is consumed and repeated unsuccessful attempts to abstain from consumption, as well as commonalities in brain structures involved in food and drug craving. To date, very little attention has been given to an additional behavioral symptom that BED shares with SUDs-sleep dysregulation-and the extent to which this may contribute to the pathophysiology of BED. Here, we review studies examining sleep outcomes in patients with BED, which collectively point to a heightened incidence of sleep abnormalities in BED. We identify the orexin (hypocretin) system as a potential neurobiological link between compulsive eating and sleep dysregulation in BED, and provide a comprehensive update on the evidence linking this system to these processes. Finally, drawing on evidence from the SUD literature indicating that the orexin system exhibits significant plasticity in response to drugs of abuse, we hypothesize that chronic palatable food consumption likewise increases orexin system activity, resulting in dysregulated sleep/wake patterns. Poor sleep, in turn, is predicted to exacerbate binge eating, contributing to a cycle of uncontrolled food consumption. By extension, we suggest that pharmacotherapies normalizing orexin signaling, which are currently being trialed for the treatment of SUDs, might also have utility in the clinical management of BED.

Abstract
Ability to restrain one's dietary intake is a necessary skill for weight loss. However, dietary restraint has been shown to paradoxically increase disinhibited eating in certain populations, thereby negatively impacting weight loss and leading to worse overall health outcomes. The aim of this study was to address gaps in the literature regarding the relationships between separate facets of dietary restraint (intention; behavior) with weight loss and various types of disinhibited eating (binge eating, external eating, emotional eating) in overweight and obese adults who recently completed a weight loss intervention. A sample of mostly male Veterans with overweight and obesity (N = 88) self-reported their dietary restraint intention, restraint behavior, and current disinhibited eating following completion of an 8-week behavioral weight loss treatment. Greater dietary restraint intention was related to greater dietary restraint behavior, p < .05. Greater dietary restraint behavior was significantly related to greater recent weight loss, p < .05, while restraint intention was not, p > .05. Greater dietary restraint intention was related to greater current binge eating and external eating, while greater self-reported restraint behavior was related to less binge eating, p < .05. Thus, dietary restraint behavior appears to be adaptive for this population, whereas rigid dietary restraint intention may increase risk for disinhibited eating. To decrease disinhibited eating and improve weight loss outcomes in Veterans, interventions might specifically address rigid rule-following associated with abandonment of weight loss goals and help Veterans develop specific yet flexible eating plans. Future research should examine whether dietary restraint intention and behavior differentially predict disinhibited eating and weight loss outcomes prospectively.

Abstract
The prevalence of obesity with comorbid binge eating behaviour is growing at a faster rate than that seen for either obesity or eating disorders as separate conditions. Approximately 6% of the population are affected and they potentially face a lifetime of poor physical and mental health outcomes and an inability to sustain long-term weight loss. Current treatment options are inadequate in that they typically address either obesity or eating disorders exclusively, not the combination of both conditions. By treating one condition without treating the other, relapse is common, and patients are often left disappointed with their lack of weight loss. An integrated approach to treating these individuals is needed to prevent a worsening of the comorbidities associated with excess body weight and eating disorders. A new therapy has recently been developed, named HAPIFED, which addresses both overweight/obesity and comorbid binge eating behaviour with the combination of behavioural weight loss therapy and cognitive behaviour therapy-enhanced (CBT-E). The aim of this paper is to document the protocol for the Real Happy Study, which will evaluate the effectiveness of the HAPIFED program in treating overweight or obesity with comorbid binge-eating behaviour in a real-world setting.

Abstract
PURPOSE OF REVIEW In 2013, binge eating disorder (BED) was officially recognized as a distinct eating disorder in the Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders. The purpose of this review is to assess the available epidemiological data to determine whether BED should be considered for inclusion in global disease burden quantification efforts, such as the Global Burden of Disease Study (GBD). RECENT FINDINGS A systematic search of three electronic databases (PubMed, EMBASE, and PsycINFO) found 32 studes meeting GBD inclusion criteria. The global pooled prevalence of BED was 0.9% (95% confidence intervals: 0.7-1.0%). Although women (1.4%, 1.1-1.7%) had higher prevalence than men (0.4%, 0.3-0.6%), no significant difference in prevalence was found between high-income countries (0.9%, 0.8-1.1%) and low- and middle-income countries (0.7%, 0.3-1.1%). SUMMARY The current article presents the findings of a recent systematic review of the epidemiology of BED and discusses the case for including BED as a new cause in future iterations of GBD.

Epidemic obesity in children and adolescents: risk factors and prevention. Front Med 2018; 12:658-666.

Abstract
The prevalence of obesity among children and adolescents (aged 2-18 years) has increased rapidly, with more than 100 million affected in 2015. Moreover, the epidemic of obesity in this population has been an important public health problem in developed and developing countries for the following reasons. Childhood and adolescent obesity tracks adulthood obesity and has been implicated in many chronic diseases, including type 2 diabetes, hypertension, and cardiovascular disease. Furthermore, childhood and adolescent obesity is linked to adulthood mortality and premature death. Although an imbalance between caloric intake and physical activity is a principal cause of childhood and adolescent obesity, environmental factors are exclusively important for development of obesity among children and adolescents. In addition to genetic and biological factors, socioenvironmental factors, including family, school, community, and national policies, can play a crucial role. The complexity of risk factors for developing obesity among children and adolescents leads to difficulty in treatment for this population. Many interventional trials for childhood and adolescent obesity have been proven ineffective. Therefore, early identification and prevention is the key to control the global epidemic of obesity. Given that the proportion of overweight children and adolescents is far greater than that of obesity, an effective prevention strategy is to focus on overweight youth, who are at high risk for developing obesity. Multifaceted, comprehensive strategies involving behavioral, psychological, and environmental risk factors must also be developed to prevent obesity among children and adolescents.

Abstract
Obesity and eating disorders are each associated with severe physical and mental health consequences, and individuals with obesity as well as comorbid eating disorders are at higher risk of these than individuals with either condition alone. Moreover, obesity can contribute to eating disorder behaviors and vice-versa. Here, we comment on the health complications and treatment options for individuals with obesity and comorbid eating disorder behaviors. It appears that in order to improve the healthcare provided to these individuals, there is a need for greater exchange of experiences and specialized knowledge between healthcare professionals working in the obesity field with those working in the field of eating disorders, and vice-versa. Additionally, nutritional and/or behavioral interventions simultaneously addressing weight management and reduction of eating disorder behaviors in individuals with obesity and comorbid eating disorders may be required. Future research investigating the effects of integrated medical, psychological and nutritional treatment programs addressing weight management and eating disorder psychopathology in individuals with obesity and comorbid eating disorder behaviors—such as binge eating—is necessary.

Abstract
Recent research suggests that obese individuals with binge eating disorder (BED) show deficits in response inhibition, but findings are not consistent, especially when food-associated stimuli are presented. The aim of the present study was to assess the role of moderating factors by taking into account restrained eating and mood. Seventeen obese women with BED, 20 obese women without BED and 20 normal-weight controls (NW) were recruited. A go/no-go task with food-associated and control stimuli and questionnaires were administered. Obese BED showed less impairment of response inhibition to food-associated than to control stimuli, while this pattern was reversed in NW; no differences were observed for obese participants. Interestingly, group differences were moderated by the interaction of restrained eating and mood, and obese BED made the most commission errors to food-associated stimuli when they were restrained eaters and in a very positive mood at the time of testing. Our results might explain why some studies did not observe deficits in response inhibition to food-associated cues in BED.

Abstract
The Risk factors for Binge Eating Disorder in Overweight (REO) questionnaire is a screening tool for nutritionists to discriminate between individuals with obesity with and without Binge Eating Disorder (BED). The first study tested the discriminative ability of the REO and identified an optimal cut-off value. In the second study this cut-off value was used to identify individuals with and without BED from a sample of individuals with obesity visiting a nutritionist and compared clinical and personality characteristics with a group of individuals officially diagnosed with BED. Results showed that the REO has a sensitivity of 95.1%, specificity of 81.5%, a good internal consistency of α=.96, and an exploratory factor analysis showed four underlying factors of the REO that explained a total variance of 63.7%. Characteristics of individuals with BED symptoms identified by the REO and those officially diagnosed with BED were comparable and differed from individuals with obesity without BED symptoms. By screening individuals with obesity with the REO those presenting with BED symptoms are more easily identified, and can be referred to psychological treatment facilities for further assessment and appropriate treatment.

Abstract
OBJECTIVE To investigate behavioral factors that contribute to the development of obesity among overweight children. METHODS Among a community sample of 884 children aged 9-13 years, 833 children completed a baseline and 1-year follow-up examination that included anthropometrics, physical fitness, and behavioral factors. RESULTS During the follow-up period, BMI for most children with normal weight or obesity did not change. However, among overweight children (n = 100), about one-third developed obesity (n = 26), while the others were categorized as normal weight (n = 32) or overweight (n = 42) after 1 year. Characteristics of overweight children at baseline and follow-up were analyzed. Those who developed obesity showed a notable increase in blood pressure as well as in BMI, waist circumference, and body fat over 1 year. At baseline, this group spent more time studying after school compared to overweight children who did not develop obesity, while there were no differences in time spent viewing television or engaging in vigorous physical activity. Eating outside the home, fast food consumption, and habitual eating in the absence of hunger were more common at baseline in those who did versus those who did not develop obesity. After adjusting for age, sex, and BMI, spending more time studying after school and habitual eating without hunger were associated with the development of obesity. CONCLUSION Among Korean overweight children, study time after school and habitual eating without hunger were associated with an increased risk for development of obesity.

Neurobiological evidence for attention bias to food, emotional dysregulation, disinhibition and deficient somatosensory awareness in obesity with binge eating disorder. Physiol Behav 2017; 184:122-128. [PMID: 29128522 DOI: 10.1016/j.physbeh.2017.11.003] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2017] [Revised: 10/11/2017] [Accepted: 11/05/2017] [Indexed: 01/14/2023]
Abstract
OBJECTIVES To refine the biobehavioral markers of binge eating disorder (BED). METHODS We conducted fMRI brain scans using images of high energy processed food (HEPF), low energy unprocessed food (LEUF), or non-foods (NF) in 42 adults (obese with BED [obese -BED; n=13] and obese with no BED [obese non-BED; n=29]) selected via ads. Two blood oxygenated level dependent (BOLD) signal contrast maps were examined: food versus nonfood, and HEPF versus LEUF. In addition, score differences on the disinhibition scale were correlated with BOLD signals. RESULTS food versus nonfood showed greater BOLD activity for BED in emotional, motivational and somatosensory brain areas: insula, anterior cingulate cortex (ACC), Brodmann areas (BA) 19 & 32, inferior parietal lobule (IPL), posterior cingulate cortex (PCC), and lingual, postcentral, middle temporal and cuneate gyri (p≤0.005; k≥88). HEPF versus LEUF showed greater BOLD activity for BED in inhibitory brain regions: BA 6, middle and superior frontal gyri (p<0.01; k≥119). The groups also differed in the relationships between disinhibition and BOLD activity in the postcentral gyrus (PCG; p=0.04) and ACC-BA 32 (p=0.02). For all participants jointly, PCG BOLD amplitude predicted greater disinhibition (p=0.04). DISCUSSION Food images elicited neural activity indicating attention bias (cuneate & PCG), emotion dysregulation (BA 19 & 32), and disinhibition (MFG, BA6 & SFG) in obese with BED. These may help tailor a treatment for the obesity with BED phenotype.

Abstract
OBJECTIVE This study aims to assess whether an intensive lifestyle intervention (ILI) for weight reduction precipitates binge eating (BE) and whether BE attenuates 4-year weight loss among participants with type 2 diabetes and overweight or obesity. METHODS Participants (N = 4,901) were from Look AHEAD, a randomized controlled trial that compared ILI to diabetes support and education (DSE). Annual assessments of measured weight and self-reported BE were used. By using the yearly time points when a person endorsed BE, participants were classified as no BE, remitted BE, incident BE, inconsistent BE (2-3 years, including baseline), and consistent BE (≥ 4 years, including baseline). Cox regression and mixed-effects models were used for analyses. RESULTS ILI participants were marginally more likely to report incident BE at year 4 than those in DSE (P = 0.06). At year 4, ILI participants with remitted BE lost more weight (4.7 ± 0.8%) than those with consistent BE (1.9 ± 1.0%; P = 0.03). ILI participants with no BE lost more weight (4.6 ± 0.2%) than those with incident BE (3.1 ± 0.6%; P = 0.02) and consistent BE (P = 0.01). DSE participants with remitted BE lost more weight than those with incident and consistent BE. CONCLUSIONS Preexisting BE did not seem to be a contraindication for ILI, although persistent BE attenuated weight loss. Patients who report new or ongoing BE may need additional treatment.

Abstract
Some individuals may have an addictive-like response to certain foods, possibly contributing to problematic eating. Highly processed foods, with added fats and/or refined carbohydrates, are suggested to be most associated with addictive-like eating. The incentive sensitization theory suggests that wanting (e.g. craving) may drive compulsive drug use rather than liking (e.g. enjoyment), but it is unknown whether highly processed foods elicit similar wanting and liking patterns as drugs of abuse, or whether individual differences exist. The current study examines the association of highly processed foods with craving and liking, and whether these relationships differ by food addiction symptomology, cognitive restraint, or body mass index (BMI). Participants (n = 216) reported craving and liking for 35 foods and completed the Yale Food Addiction Scale (YFAS) and Three Factor Eating Questionnaire (TFEQ). Highly processed foods were craved more overall. Craving of highly processed foods was predicted negatively by restraint and positively by YFAS score. Liking of highly processed foods was predicted negatively by restraint and positively by BMI. In conclusion, craving and liking appear distinct with respect to highly processed foods, and may be influenced by addictive-like eating, cognitive restraint, and BMI. This suggests that the incentive sensitization framework may also be relevant for problematic food consumption, especially for individuals reporting food addiction symptoms.

Abstract
OBJECTIVE To investigate the performance of a simple and developmentally appropriate 10-item questionnaire (Adolescent Binge Eating Scale) for the prediction of binge eating disorder (BED) diagnosis in adolescents seen for obesity. STUDY DESIGN We evaluated the performance of the questionnaire in comparison with a clinical interview, in a population of adolescents being seen for obesity. The ?2 or Fisher exact tests were used. RESULTS There were 94 adolescents aged 12-18 years (59.6% girls) who completed the study. The questionnaire demonstrated a good association with the clinical interview and distinguished different levels of risk for having a BED: participants who responded positively to questions 1 or 2 and had more than 6 positive answers to the 8 additional questions had a high risk of subclinical and clinical BED (83.3%); participants with 3 or fewer positive answers had a low risk of clinical BED (4%). CONCLUSIONS The Adolescent Binge Eating Scale questionnaire is a potential screening tool to identify adolescents with obesity at high risk of BED and guide referral to a specialist to clarify the diagnosis and provide adequate care.

Abstract
BACKGROUND Despite the theoretical links between eating disorders and perfectionism, the definition of perfectionism in practice is complicated. The present study explored descriptions and experiences of perfectionism described by a transdiagnostic sample of patients. METHODS In-depth, semi-structured interviews were carried out with 15 patients. The interviews were analyzed by Thematic Analysis. A comparison between the patients' scorings on the Eating Disorder Inventory-Perfectionism scale was also performed. RESULTS Seven themes were found: The origins of perfectionism, Top performance, Order and self-control, A perfect body, Looking good in the eyes of others, A double-edged coping strategy, and A Sisyphean task. The women in this study did not emphasize weight and body as the main perfectionistic strivings. Core descriptions were instead order, self-control and top performances. All of the participants described the awareness of reaching perfectionism as impossible. Scorings of self-oriented perfectionism was significantly higher compared to socially prescribed perfectionism. No differences in the narratives related to perfectionism scores or eating disorder diagnoses were found. CONCLUSIONS The results showed that psychometric measures do not always capture the patients' definitions of perfectionism, but regarding that perfectionism serves as a means to regulate affects and may lead into an exacerbation of the eating disorder, and the development of obsessive-compulsive symptoms, it is important to investigate the personal definitions of perfectionism.

Abstract
Based on Wegner’s Ironic Processing Theory, this study examines the effects of suppressing eating-related thoughts in a sample of 77 female students. A distinction was made between disinhibited restrainers (high dietary restraint/high disinhibition), inhibited restrainers (high dietary restraint/low disinhibition) and low restrainers. Results indicate that disinhibited restrainers used thought suppression more often and were the only group to show a rebound effect for eating-related thoughts after suppression. No effects of suppression on willingness and desire to eat emerged. Hence, thought suppression may be counterproductive at least for a subgroup of restrainers and may fuel eating-related preoccupations. More research is required to evaluate effects on eating behaviour.

Abstract
Scientific interest in "food addiction" is growing, but the topic remains controversial. One critique of "food addiction" is its high degree of phenotypic overlap with binge eating disorder (BED). In order to examine associations between problematic eating behaviors, such as binge eating and "food addiction," we propose the need to move past examining similarities and differences in symptomology. Instead, focusing on relevant mechanisms may more effectively determine whether "food addiction" contributes to disordered eating behavior for some individuals. This paper reviews the evidence for mechanisms that are shared (i.e., reward dysfunction, impulsivity) and unique for addiction (i.e., withdrawal, tolerance) and eating disorder (i.e., dietary restraint, shape/weight concern) frameworks. This review will provide a guiding framework to outline future areas of research needed to evaluate the validity of the "food addiction" model and to understand its potential contribution to disordered eating.

Abstract
Severe dietary energy restriction is often used for overweight or obese individuals to achieve rapid weight loss and related health improvements. However, the extent of putative adverse effects on eating behaviour is unknown. We thus systematically searched seven databases for studies that assessed binge eating before and after severe dietary energy restriction (low or very low energy diets) in overweight or obese individuals. Fifteen clinically supervised interventions from 10 publications (nine of which involved only women) were included. Among individuals with clinically relevant pre-treatment binge eating disorder, severe dietary energy restriction significantly decreased binge eating in all four interventions involving this population, at least during the weight loss programme. In contrast, no consistent association between severe dietary energy restriction and the onset of bingeing was found in 11 interventions involving individuals without pre-treatment binge eating disorder, with four such interventions showing significant increases, two showing no change, and five showing significant decreases in binge eating. We conclude that clinically supervised severe dietary energy restriction appears safe and beneficial for overweight or obese individuals with pre-treatment binge eating disorder, and does not necessarily trigger binge eating in those without binge eating disorder.

Abstract
Obesity, a common health condition in adolescence leading to severe medical complications, is assumed to be influenced by temperament factors. This paper investigates associations between reactive and regulative temperament, problematic eating behaviours and excess weight. Several self-report instruments were completed by 130 adolescents (mean age 14.13 ± 0.61 years), including 27 overweight and obese individuals (20.8%). Bootstrap analysis revealed a mediating effect of restrained eating on the relation between reactive temperament and body mass index percentile, which differed according to gender: Restrained eating, which predicted weight gain, was more present in girls having a higher sensitivity to reward and in boys showing a higher sensitivity to punishment. No effect of regulative temperament was found. These results have important implications for weight management programmes, as they suggest that reducing restrained eating by working on temperament may help to control weight.

Abstract
BACKGROUND AND OBJECTIVES A number of correlational studies suggest that the combined presence of perfectionism and body dissatisfaction creates elevated risk for the development of eating disorder pathology. The aim of this study was to examine the causal role of this combination of risk factors for eating pathology. METHOD We conducted an experimental study in a sample of female college students (N = 47). Specifically, we performed an experimental manipulation of perfectionism and examined whether this manipulation would interact with body dissatisfaction to predict eating disorder symptoms. RESULTS We found that the effect of the experimental manipulation was moderated by body dissatisfaction, such that women in the perfectionism condition and scoring high on body dissatisfaction exhibited the highest levels of eating disorder symptoms. LIMITATIONS The sample was rather small (resulting in limited statistical power) and the participants were predominantly healthy and well-adjusted women, which may limit the generalizability and interpretation of our findings. CONCLUSIONS The results suggest that the combination of perfectionism and body dissatisfaction is particularly detrimental and predictive of risk for eating disorder symptoms.

Abstract
Eating dyscontrol constitutes a potential negative predictor for the outcome of treatment strategies for obese patients. The aim of this study was to examine the qualitative characteristics of eating dyscontrol in obese patients who engage in binge eating (BE) compared with those who do not (NBE), and to analyse the relationship between eating dyscontrol and axis-I, axis-II, spectrum psychopathology using instruments that explore mood, panic-agoraphobic, social-phobic, obsessive-compulsive and eating disorders spectrum psychopathology (SCI-MOODS-SR, SCI-PAS-SR, SCI-SHY-SR, SCI-OBS-SR, SCI-ABS-SR). This was a cross-sectional study involving a clinical sample of adult obese patients with severe obesity (average body mass index = 45 ± 8 kg m(-2) ) and candidate to bariatric surgery who were recruited between November 2001 and November 2010 at the Obesity Center of the Endocrinology Unit, University Hospital of Pisa. All participants completed a face-to-face interview, including a diagnostic assessment of axes-I and II mental disorders (using the Structured Clinical Interview for Manual of Mental Disorders, fourth edition [SCID]-I and SCID-II) and filled out self-report spectrum instruments. Among obese patients not affected by BE, eating dyscontrol was highly represented. Indeed, 39.7% (N = 177) of subjects endorsed six or more items of the Anorexia-Bulimia Spectrum Self-Report, lifetime version domain exploring this behaviour. The cumulative probability of having axis-I, axis-II and a spectrum condition disorder increased significantly with the number of eating dyscontrol items endorsed. In both BE and NBE obese subjects, eating dyscontrol may represent an independent dimension strongly related to the spectrum psychopathology and axes I/II disorders. A systematic screening for eating dyscontrol symptoms by means of self-report spectrum instruments may be valuable to assign specific treatment strategies.

[PMID: 25058649 DOI: 10.1016/j.appet.2014.07.022] [Citation(s) in RCA: 57] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2013] [Revised: 06/11/2014] [Accepted: 07/18/2014] [Indexed: 01/11/2023]
Abstract
Stice's (1994, 2001) dual pathway model proposed a mediational sequence that links body dissatisfaction to lack of control over eating through dieting and negative affect. Van Strien et al. (2005) extended the negative affect pathway of the original dual pathway model by adding two additional intervening variables: interoceptive deficits and emotional eating. The purpose of this study was to test and compare the original and extended model using prospective data. Both types of loss of control over eating (i.e., subjective and objective binge eating) were evaluated. Data collected from 361 adolescent girls, who were interviewed and completed self-report measures annually over a 2-year period, were analysed using structural equation modeling. Although both models provided a good fit to the data, the extended model fit the adolescent girls' sample data better and accounted for a greater proportion of variance in binge eating than the original model. All proposed mediational pathways of both models were supported and all indirect effects examined through bootstrap procedure were significant. Although our results confirmed the validity of both models and extended previous findings to an early- to middle adolescent group, the bi-directional relationship between dietary restriction and negative affect suggests that the association between these key risk factors for binge eating are more complex than outlined in both the original and extended dual-pathway models.

Stress-related eating, obesity and associated behavioural traits in adolescents: a prospective population-based cohort study. BMC Public Health 2014; 14:321.

Abstract
BACKGROUND Stress-related eating is associated with unhealthy eating and drinking habits and an increased risk of obesity among adults, but less is known about factors related to stress-driven eating behaviour among children and adolescents. We studied the prevalence of stress-related eating and its association with overweight, obesity, abdominal obesity, dietary and other health behaviours at the age of 16. Furthermore, we examined whether stress-related eating is predicted by early-life factors including birth size and maternal gestational health. METHODS The study population comprised 3598 girls and 3347 boys from the Northern Finland Birth Cohort 1986 (NFBC1986). Followed up since their antenatal period, adolescents underwent a clinical examination, and their stress-related eating behaviour, dietary habits and other health behaviours were assessed using a postal questionnaire. We examined associations using cross-tabulations followed by latent class analysis and logistic regression to profile the adolescents and explain the risk of obesity with behavioural traits. RESULTS Stress-related eating behaviour was more common among girls (43%) than among boys (15%). Compared with non-stress-driven eaters, stress-driven eaters had a higher prevalence of overweight, obesity and abdominal obesity. We found no significant associations between stress-eating and early-life factors. Among girls, tobacco use, shorter sleep, infrequent family meals and frequent consumption of chocolate, sweets, light sodas and alcohol were more prevalent among stress-driven eaters. Among boys, the proportions of those with frequent consumption of sausages, chocolate, sweets, hamburgers and pizza were greater among stress-driven eaters. For both genders, the proportions of those bingeing and using heavy exercise and strict diet for weight control were higher among stress-eaters. Besides a 'healthy lifestyle' cluster, latent class analysis revealed two other patterns ('adverse habits', 'unbalanced weight control') that significantly explained the risk of overweight among boys and girls. CONCLUSIONS Stress-related eating is highly prevalent among 16-year-old girls and is associated with obesity as well as adverse dietary and other health behaviours among both genders, but intrauterine conditions are seemingly uninvolved. In terms of obesity prevention and future health, adolescents who use eating as a passive way of coping could benefit from learning healthier strategies for stress and weight management.

Abstract
OBJECTIVE This paper introduces health professionals to the different psychological models thought to influence eating behaviour in the absence of hunger in children who are obese and to propose a method of assessing these behaviours in practice. METHODS Clinical researchers from the European Childhood Obesity Group (ECOG) adopted an evidence-based approach to examine the literature concerning the assessment of eating behaviour in children who are obese. Studies published in English were filtered out of the medical and psychological literature from 1960 to the present, and the resulting bibliography was searched for relevant articles. Key themes from the current evidence were compiled and classified according to the underpinning psychological models. Based on the current evidence and the authors' combined clinical experience, a three-staged approach to assessment was agreed by consensus. RESULTS Valid and reliable tools for assessing and monitoring each of the three identified models (Dietary Restraint Theory, Emotional Eating and the Diathesis-Stress Model) are suggested for use in clinical practice, and the ECOG three-staged approach to assessing eating behaviours in the absence of hunger is described. CONCLUSIONS This paper presents practical guidance on how to assess eating behaviour in the absence of hunger in children who are clinically obese and suggests a focus for future research.

Abstract
Research has focused on understanding how overeating can affect brain reward mechanisms and subsequent behaviors, both preclinically and in clinical research settings. This work is partly driven by the need to uncover the etiology and possible treatments for the ongoing obesity epidemic. However, overeating, or non-homeostatic feeding behavior, can occur independent of obesity. Isolating the variable of overeating from the consequence of increased body weight is of great utility, as it is well known that increased body weight or obesity can impart its own deleterious effects on physiology, neural processes, and behavior. In this review, we present data from three selected animal models of normal-weight non-homeostatic feeding behavior that have been significantly influenced by Bart Hoebel's 40+-yr career studying motivation, feeding, reinforcement, and the neural mechanisms that participate in the regulation of these processes. First, a model of sugar bingeing is described (Avena/Hoebel), in which animals with repeated, intermittent access to a sugar solution develop behaviors and brain changes that are similar to the effects of some drugs of abuse, serving as the first animal model of food addiction. Second, another model is described (Boggiano) in which a history of dieting and stress can perpetuate further binge eating of palatable and non-palatable food. In addition, a model (Boggiano) is described that allows animals to be classified as having a binge-prone vs. binge-resistant behavioral profile. Lastly, a limited access model is described (Corwin) in which non-food deprived rats with sporadic limited access to a high-fat food develop binge-type behaviors. These models are considered within the context of their effects on brain reward systems, including dopamine, the opioids, cholinergic systems, serotonin, and GABA. Collectively, the data derived from the use of these models clearly show that behavioral and neuronal consequences of bingeing on a palatable food, even when at a normal body weight, are different from those that result from simply consuming the palatable food in a non-binge manner. These findings may be important in understanding how overeating can influence behavior and brain chemistry.

Abstract
This study examined the correlates of race, weight status, and binge eating among 715 female undergraduate students (77% Caucasian; 13% African American) enrolled at an urban university. Approximately 21.7% of Caucasians and 36.8% of African-Americans (AA) were overweight/obese. Higher BMI was associated with BED, and severity of binge eating symptoms. After removing participants who endorsed compensatory behaviors ≥ 1×/week from the analyses, 8.4% of the sample met criteria for BED (2.4% of the AA and 9.9% of the Caucasian students) and 44% reported severe binge eating symptoms. AA students were less likely to have BED than Caucasian students and reported less severe binge eating symptomatology. For Caucasian students, mood, cognitive restraint, drive for thinness, and BMI all contributed significant individual variance in binge eating severity. For African Americans, mood, body image dissatisfaction, and drive for thinness were found to be unique contributors. For those meeting criteria for BED, retrospectively recalled predictors of binge eating included negative affect (e.g., self-anger, worry, guilt), but not hunger. Behavioral triggers for binge behavior differed by race, as well, with African American students retrospectively reporting lower levels of anxiety prior to bingeing. Results from this study suggest that there are racial differences in binge eating behaviors. Future studies are needed to examine differences in eating practices among racial groups (e.g., grazing, large portions, high fat food preparation) that may contribute to early onset weight gain and obesity. The results suggest the importance of sensitive tailored weight and disordered eating interventions for college women from diverse backgrounds.

Abstract
The present study was planned to investigate differences in psychopathological features, eating behaviour and eating habits between obese women with and without BED. It also aimed to identify specific relationships between affective symptoms and eating behaviour in obese women with BED. Eighty-four obese women were studied (40 with BED, 44 non-BED). Psychiatric comorbidities were assessed with the structured diagnostic interview for DSM-IV (SCID). Depressive symptoms were measured with the Beck Depression Inventory (BDI) and anxiety with the state-trait anxiety inventory (STAI). Eating habits (emotional and restrained eating) were assessed by the Dutch eating behaviour questionnaire (DEBQ). Food diaries were used for assessing naturalistic eating behaviour (food intake) and mood before and after food intake. BED subjects exhibited higher levels of comorbidity (in particular mood disorders, anxiety disorders and substance-related disorders), higher depressive symptoms, trait anxiety, external and emotional eating scores than non-BED subjects. Regression analyses revealed that anxiety and emotional eating were significant predictors for BED status. In the BED group, depressive symptoms were significantly related to emotional eating and food intake and negatively related to restraint. Anxiety was significantly related to emotional eating. In general, food intake significantly enhanced mood. Mood was worse on the days with self-reported binge eating episodes than on nonbinge days. These results are discussed with regard to aetiological models for BED and for BED being a distinct diagnostic category separate from obesity.

Abstract
OBJECTIVE Therapeutic programs for binge eating disorder (BED) often include the mediation of problem-solving skills to deal with the desire to binge. In women with BED, problem-solving abilities have not been studied yet. Knowing that reasons for binge episodes are often linked to interpersonal topics, we expected women with BED to have poorer problem-solving abilities than healthy controls (HC). METHODS Twenty-five women with BED and 30 overweight HC were given a shortened version of the Means-Ends Problem-Solving Procedure (MEPS). Dependent variables were the number of relevant means, the effectiveness and the specificity of the generated solution. RESULTS Generated solutions in the group of women with BED were significantly less effective and less specific compared to HC. Moreover, reduced effectiveness of interpersonal problem-solving was related to increased binge frequency. CONCLUSIONS The results support the importance of teaching problem-solving ability in individuals with BED to promote behaviour change.

Abstract
Previous research has yielded evidence of attentional biases for food-related cues in binge eating disorder (BED) using behavioural measures such as the Stroop and dot probe paradigm. Being a more direct measure of attentional processing, the present study used event related potentials (ERPs) to test reactivity to high caloric and low caloric food pictures in women with BED compared to overweight healthy female controls (HC). In order to detect a possible motivational ambivalence, self-report and psychophysiological measures of the sympathetic and parasympathetic response system were assessed additionally. The main results yielded evidence that in women with BED high caloric food pictures elicit larger long latency ERPs compared to HC. By contrast, no such group difference was found for low caloric food pictures. Peripheral measures did not yield any group differences with respect to the processing of the caloric value of food. The results suggest that for women with BED, high caloric food may have high motivational properties and consume large parts of attentional resources. In the context of an environment in which high caloric food is omnipresent, such an abnormal processing may be relevant for the maintenance of the disorder.

Abstract
BACKGROUND & AIMS To consider the hypothesis that addiction to food, or more specifically sucrose, plays a role in obesity and eating disorders. METHODS By considering the relevant literature a series of predictions were examined, derived from the hypothesis that addiction to sucrose consumption can develop. Fasting should increase food cravings, predominantly for sweet items; cravings should occur after an overnight fast; the obese should find sweetness particularly attractive; a high-sugar consumption should predispose to obesity. More specifically predictions based on the hypothesis that addiction to sugar is central to bingeing disorders were developed. Dieting should predate the development of bingeing; dietary style rather than psychological, social and economic factors should be predispose to eating disorders; sweet items should be preferentially consumed while bingeing; opioid antagonists should cause withdrawal symptoms; bingeing should develop at a younger age when there is a greater preference for sweetness. RESULTS The above predications have in common that on no occasion was the behaviour predicted by an animal model of sucrose addiction supported by human studies. CONCLUSION There is no support from the human literature for the hypothesis that sucrose may be physically addictive or that addiction to sugar plays a role in eating disorders.

Abstract
Even though eating is frequently driven by overindulgence and reward rather than by energy balance, few studies so far have analyzed decision-making processes and disturbances in feedback processing in women with binge eating disorder (BED). In an experimental study, 17 women with BED (DSM-IV) and 18 overweight healthy controls (HC) were compared in the game of dice task (GDT). This task assesses decision-making under risk with explicit rules for gains and losses. Additionally, differences in dispositional activation of the behavior inhibition and behavior approach system as well as cognitive flexibility were measured. Main results revealed that women with BED make risky decisions significantly more often than HC. Moreover, they show impaired capacities to advantageously utilize feedback processing. Even though these deficits were not related to disease-specific variables, they may be important for the daily decision-making behavior of women with BED, thus being relevant as a maintenance factor for the disorder.

Abstract
Endogenous opioids and μ-opioid receptors (MORs) have long been implicated in the mechanism of appetite control and, in particular, hedonic processes associated with food evaluation, consumption and orosensory reward processes. In animal models of binge eating, selective MOR antagonists suppress food consumption. In humans, non-selective opioid receptor antagonists reduce hedonic taste preferences and food intake, particularly for palatable foods, and cause short-term weight loss. These effects have been linked to direct stimulation of MORs and modulation of dopamine release within the reward circuitry including the nucleus accumbens. These findings suggest that reduction of MOR-mediated hedonic and motivation processes driving consumption of highly palatable foods may be a promising therapeutic approach and provide a strong rationale for developing safer and more selective MOR antagonists or inverse agonists for disorders of 'appetitive motivation' including obesity and binge-eating disorder.

Abstract
The Diagnostic and Statistical Manual of Mental Disorders [American Psychiatric Association. (1994). Diagnostic and statistical manual of mental disorders (4th ed.). Washington, DC: Author.] lists weight change and appetite disturbance as a single compound symptom of depression at all ages. Nonetheless, assessment of these symptoms is complicated during adolescence by normative increases in body weight and appetitive drive as well as heightened rates of body dissatisfaction, dieting, and eating disorders. This review outlines biological and psychological mechanisms that may change the relation of weight change and appetite disturbance to depression during adolescence. We propose a developmental model of the relation of these symptoms to the disorder and use the model as a framework to summarize findings, limitations, and future directions of research. Although the literature suggests that weight change and appetite disturbance are related to adolescent depression, preliminary evidence suggests that interpretation of weight and appetite symptoms may depend on developmental level.

Abstract
OBJECTIVE This study investigated domain-specific (appearance, interpersonal, and academic) interactive relationships of perfectionism, self-efficacy, and stress to dieting and binge eating, positing that the level of weight/shape self-efficacy would be pivotal in identifying elevated dieting versus elevated binge eating. METHOD Participants were 406 randomly selected undergraduate women. At two time points (T1 and T2), 11 weeks apart, participants completed measures of dieting and binge eating attitudes/behaviors as well as domain-specific measures of perfectionism and self-efficacy (e.g., perfectionism related to appearance). Between T1 and T2, participants completed inventories weekly on the previous week's weight/shape, interpersonal, and academic stressors. RESULTS The combination of high interpersonal perfectionism, low interpersonal self-efficacy, high interpersonal stress, and high weight/shape self-efficacy was associated with the most elevated dieting. The hypothesized interactions related to the appearance and academic domains where not supported. CONCLUSION These results highlight the interpersonal context for dieting and the unique relationship between weight/shape self-efficacy and dieting.

Abstract
Differences in eating styles between overweight and normal-weight youngsters were investigated with a child version of the Dutch Eating Behavior Questionnaire (DEBQ). Subjects were children ( n = 1458; M: 10.1; SD = 1.3) and adolescents ( n = 1016; M: 14.9; SD =1.5). Overweight adolescent girls scored high on emotional eating while overweight adolescent boys displayed more external eating. In overweight children, already 10.5 per cent displayed emotional eating and 38.4 per cent reported external eating. All overweight youngsters reported restrained attitudes. Eating styles were positively associated with indicators of eating pathology. The results suggest the use of appropriate norms that take into account the child's age, gender and overweight status.

Abstract
Personality traits can give a fuller understanding for eating behaviors in obesity. The objective was to describe eating behavior (Dutch Eating Behaviour Questionnaire) in terms of the Big Five personality traits (NEO Personality Inventory-Revised) in obesity patients (n=442). Emotional eating was strongly positively associated to Neuroticism, in particular impulsiveness and depression, and further linked to lower Conscientiousness mainly seen in lower self-discipline, and lower Extraversion. External eating was likewise mainly associated to the facets impulsiveness and lower self-discipline. Restrained eating was on the other hand related to higher Conscientiousness, Extraversion and Openness, and lower Neuroticism. These results imply that poor self-control seen in impulsiveness and lower self-discipline was most important for eating due to negative emotions as well as in response to external food stimuli, suggesting that the inhibition of eating and difficulties to govern ones behavior are major aspects of these eating behaviors. Attempts to control food intake and body weight seen in restrained eating were associated with more character strengths and ambitions, and also a more outgoing personality style with more stable emotions.

Abstract
OBJECTIVE Questions have been raised about the validity of binge eating disorder (BED) as psycho-pathologically distinct from other forms of overeating. Our purpose was to ascertain whether BED individuals differed in important ways from nonbinging obese adults. METHOD BED adults were recruited from the community as were weight-matched (obese) and normal-weight control (NWC) groups. All groups were equivalent for age and gender distribution, and were assessed on several personality traits and eating behaviors. RESULTS BED individuals and obese controls did not differ on the personality traits. Both were more reward sensitive, and had greater anxiousness, impulsivity, and addictive personality traits than NWC. However, BED individuals reported significantly greater hedonic eating compared with the obese, who had higher levels than NWC. CONCLUSION Our findings provided no evidence of a psychological identity unique to obese adults with BED although their eating behaviors are markedly hedonically driven-i.e., more responsive to factors external to physiological needs.

Subtyping children and adolescents with loss of control eating by negative affect and dietary restraint. Behav Res Ther 2008; 46:777-87. [PMID: 18460404 DOI: 10.1016/j.brat.2008.03.004] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2007] [Revised: 02/08/2008] [Accepted: 03/11/2008] [Indexed: 10/24/2022]
Abstract
OBJECTIVE Research suggests that subtyping adults with binge eating disorders by dietary restraint and negative affect predicts comorbid psychopathology, binge eating severity, and treatment outcome. Little research has explored the validity and clinical utility of subtyping youth along these dimensions. METHOD Children (aged 8-18 years) reporting loss of control eating (n=159) were characterized based upon measures of dietary restraint and negative affect using cluster analysis, and then compared regarding disordered eating attitudes and behaviors, and parent-reported behavior problems. RESULTS Robust subtypes characterized by dietary restraint (n=114; 71.7%) and dietary restraint/high negative affect (n=45; 28.3%) emerged. Compared to the former group, the dietary restraint/high negative affect subtype evidenced increased shape and weight concerns, more frequent binge eating episodes, and higher rates of parent-reported problems (all ps<0.05). CONCLUSION Similar to findings from the adult literature, the presence of negative affect may mark a more severe variant of loss of control eating in youth. Future research should explore the impact of dietary restraint/negative affect subtypes on psychiatric functioning, body weight, and treatment outcome.
