The contributions of weight problem perception, BMI, gender, mood, and smoking status to binge eating among college students. Eat Behav 2009; 10:1-9. [PMID: 19171310 DOI: 10.1016/j.eatbeh.2008.07.010] [Citation(s) in RCA: 55] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2008] [Revised: 05/23/2008] [Accepted: 07/29/2008] [Indexed: 11/16/2022]
Abstract
College student participants (N=1063; 77.8% response rate) completed a web-based survey assessing demographics, depression, anxiety, body image, cigarette smoking, and weight history. Among overweight participants, 42.6% of those who believed they were overweight admitted to binge eating, while only 30.1% who did not feel overweight did so (p<.05). Among non-overweight participants, 43.2% of those who believed they were overweight admitted to binge eating, while only 32.9% of those who did not feel overweight did so (p<.05). Weight Problem Perception (WPP) mediated the contribution of BMI on binge eating outcomes, and WPP contributed significantly to the prediction of binge eating, beyond the risk conferred by established correlates of binge eating (e.g., gender, mood, and cigarette smoking). Results suggest that when assessing risk for binge eating, a one-question assessment of whether or not an individual believes s/he is overweight has significant predictive power. Findings are consistent with literature on the importance of the "fat self-schema" [Stein, K.F., & Corte, C. (2007). Identity impairment and the eating disorders: Content and organization of the self-concept in women with anorexia nervosa and bulimia nervosa. European Eating Disorders Review, 15 (1), 58-69] in disordered eating and theory implicating identity in the maintenance of addictive behavior [West, R.W. (2006). Theory of Addiction.

Abstract
This study examined the association between loss of control and eating disorder psychopathology in a community sample of women of Hispanic origin. Seventy-seven monolingual Spanish-speaking Latinas recruited from the community were administered the Spanish language version of the Eating Disorders Examination (S-EDE). Latinas who reported regular (at least once weekly) loss of control-through objective bulimic episodes (OBEs) and/or subjective bulimic episodes (SBEs)-were compared with Latinas who did not report regular loss of control. Latinas who reported LOC did not differ significantly from Latinas who denied LOC in age, current body mass index, or highest adult weight. Latinas who reported LOC had significantly more frequent weight cycling and significantly higher scores on all S-EDE subscales. The findings suggest that regular loss of control over eating-regardless of the amount of food consumed-may be a marker for the presence of eating disorder psychopathology.

Abstract
OBJECTIVE To investigate obese people with/without binge-eating Disorder (BED) in terms of shared psychopathological features pertaining to spectrum of eating disorders. METHOD One-hundred obese adult patients with a BMI > 30 kg/m(2) referred to an Eating Disorder Unit and/or hospital weight-loss programs were administered the BED Clinical Interview, the Eating Disorder Inventory, and the Structured Clinical Interview for Anorexic-Bulimic Spectrum, Self-Report. RESULTS Twenty-seven subjects satisfied DSM-IV research criteria for current BED; compared to nonbingeing obese subjects, BED ones were characterized by greater weight-shape concerns influencing self-esteem (p = .05), overall impairment due to the overweight condition (p < .005), psychological distress leading to professional help (p < .001), dichotomous reasoning (p = .01) and secondary social phobia due to the overweight condition (p < .005). Compared to the other group, BED obese subjects scored higher at the following EDI subscales: bulimia (p < .0001), ineffectiveness (p < .01), interoceptive awareness and social insecurity (p < .05). CONCLUSION The results of this study highlight the role of cognitive mechanisms such as dichotomous reasoning and weight-shape concerns unduly influencing self-esteem as a hallmark of BED in obese patients, and the importance of investigating eating disorder psychopathology by adopting a dimensional perspective, rather than strictly focusing on categories when dealing with obese patients.

Abstract
BACKGROUND AND RATIONALE This review addresses the role animal models play in contributing to our knowledge about the eating disorders anorexia nervosa (AN) and bulimia nervosa (BN) and obesity. OBJECTIVES Explore the usefulness of animal models in complex biobehavioral familial conditions, such as AN, BN, and obesity, that involve interactions among genetic, physiologic, psychological, and cultural factors. RESULTS AND CONCLUSIONS The most promising animal model to mimic AN is the activity-based anorexia rodent model leading to pathological weight loss. The paradigm incorporates reward elements of the drive for activity in the presence of an appetite and allows the use of genetically modified animals. For BN, the sham-feeding preparation in rodents equipped with a gastric fistula appears to be best suited to reproduce the postprandial emesis and the defects in satiety. Animal models that incorporate genes linked to behavior and mood may clarify biobehavioral processes underlying AN and BN. By contrast, a relative abundance of animal models has contributed to our understanding of human obesity. Both environmental and genetic determinants of obesity have been modeled in rodents. Here, we consider single gene mutant obesity models, along with models of obesigenic environmental conditions. The contributions of animal models to obesity research are illustrated by their utility for identifying genes linked to human obesity, for elucidating the pathways that regulate body weight and for the identification of potential therapeutic targets. The utility of these models may be further improved by exploring the impact of experimental manipulations on the behavioral determinants of energy balance.

Abstract
OBJECTIVE To compare the prevalence of disordered eating and body dissatisfaction between adolescents with type 1 diabetes and a population-based sample of youth. SUBJECTS A clinic-based sample of 143 adolescents (73 male and 70 female) with type 1 diabetes who participated in the Assessing Health and Eating among Adolescents with Diabetes (AHEAD) study was compared with a population-based sample of 4746 youths (2377 male, 2357 female, and 12 missing) who participated in Project Eating Among Teens (Project EAT). METHOD Participants completed surveys and anthropometric measurements of height and weight. RESULTS Although some adolescents with type 1 diabetes endorsed unhealthy weight control practices, overall, they reported less weight dissatisfaction and were less likely to use any unhealthy weight control behaviors and more likely to report regular meal consumption than the population-based sample. Females with type 1 diabetes were less likely to report dieting, fasting, or eating very little food to control weight during the past year than their population-based peers. However, males with type 1 diabetes were less likely than their peers to exercise and to consume more fruits and vegetables for healthy weight control. Of medical concern were insulin omission (1.4% males and 10.3% females) and dosage reduction (1.4% males and 7.4% females) as means of weight control among youth with type 1 diabetes. CONCLUSIONS Despite medical supervision, some adolescents with type 1 diabetes reported unhealthy weight control behaviors and weight concerns, including insulin manipulation. Altering the insulin regimen may cause complications. All adolescents warrant attention for unhealthy behaviors and weight concerns.

Abstract
The worldwide increase in obesity prevalence is a result of positive energy balance, with energy intake exceeding expenditure. The eating behavior in obesity ranges from mild passive overconsumption to excessive overeating with loss of control observed in binge eating disorder (BED). The signaling systems that underlie appetite control in BED are complex and, at this point, not well understood. The present review highlights the current knowledge of key components of the gut peptide system and examines evidence of defects in signaling that differentiate obese binge eaters from obese non-binge eaters. The signaling network underlying hunger, satiety, and metabolic status includes leptin and insulin from energy stores and cholecystokinin, glucagon-like peptide-1, peptide YY(3-36), and ghrelin from the gastrointestinal tract. Of the many gastrointestinal peptides, ghrelin is the only established appetite-stimulating one, whereas cholecystokinin, glucagon-like peptide-1, and peptide YY(3-36) promote satiety. Adipose tissue provides hormonal signals via leptin and insulin to the brain about energy stores and likely from adiponectin and resistin. Binge eating has been related to a dysfunction in the ghrelin signaling system. Moreover, the larger gastric capacity observed in BED may further reduce satiety signals and contribute to overeating.

Abstract
Close to 30 forms of gonadotropin releasing hormone (GnRH) and at least five GnRH receptors have been identified in a wide variety of vertebrates and some invertebrates. One form, now called GnRH II, has the broadest distribution and the most ancient and conserved phylogeny. The distribution of the neurons that produce this peptide are completely nonoverlapping with any other GnRH forms. Fibers that project from these neurons overlap with GnRH I cells and/or fibers in a few regions, but are primarily divergent. The musk shrew (Suncus murinus) continues to be the most tractable mammalian species to use for studies of the function of GnRH II. The brain of the musk shrew has two GnRH genes (I and II), two GnRH receptors (types-1 and -2), and two different behaviors can be influenced by central infusion of GnRH II, but not by GnRH I; receptivity and feeding. Here, we summarize research on the musk shrew relative to the behavioral functions of GnRH II. First, female musk shrews are continually sexually receptive by virtue of their lack of an ovarian and/or behavioral estrus cycle. This feature of their reproductive ecology may be related to their semi-tropical distribution and their breeding season is highly dependent on changes in the availability of food. When food is not abundant, females stop mating, but brief bouts of feeding reinstate reproductive behavior. Likewise, intake of food is related to GnRH II mRNA and peptide content in the brain; after mild food restriction both decline. When GnRH II is infused centrally, at times when its content is low, it can both enhance receptivity and inhibit food intake. Simultaneous administration of a type-1 antagonist does not change the effect of GnRH II and use of an analog (135-18) that is a specific GnRH II agonist as well as a type-1 antagonist has the same effect as the endogenous GnRH II peptide. We propose that GnRH II plays a critical role by orchestrating the coordination of reproduction with the availability of nutritional support for these activities. Humans are bombarded with copious nutritional opportunities and at present obesity is a larger threat to health in many parts of the world than is under nutrition. It is our hope that understanding neuropeptides such as GnRH II that regulate food intake can ultimately lead to products that may curb appetite and thus decrease obesity and related risks to health.

Abstract
BED is characterized by overeating with a loss of control. The primary aim of the study was to measure plasma concentrations of three key gut peptides influencing hunger (ghrelin) and satiety (PYY, GLP-1) to ascertain potential abnormalities in BED. The participants were 10 obese BED and 9 obese nonBED premenopausal women. They did not differ in age, 30.1+/-8.1 SD, BMI, 36.2+/-5.9, or % body fat, 43.3+/-5.7. Following a13-h overnight fast, blood was drawn (-15, 0, 5, 15, 30, 60, 90, 120 min) for measurement of total plasma concentrations of ghrelin, PYY and GLP-1, pre and post ingestion of a nutritionally complete liquid meal (1256 kJ) at 9 am (0-5 min). Ratings of hunger and fullness preceded each blood draw. Ghrelin was significantly lower premeal at -15 min (P=.05) and postmeal at 90 min (P=.027) and 120 min (P=.025) in the BED group as compared to the nonBED group. Ghrelin also declined less postprandially in the BED group (P=.019) with a longer time to the nadir value (P=.004). However, fasting and meal-related changes in levels of PYY and GLP-1 did not differ between the groups nor did ratings of hunger and fullness. Following a randomized cognitive behavior and dietary intervention, the ghrelin values in BED normalized. Prior to treatment, the lower fasting ghrelin in BED may be a consequence of down regulation by overeating. The lack of differences in the satiety promoting hormones, PYY and GLP-1, makes them unlikely contributors to the binge eating in BED.

Abstract
In this study, we examined the prevalence of binge eating disorder (BED) and borderline personality disorder (BPD) in a sample of 121 candidates seeking surgery for obesity. In this predominantly female sample (85.9%), according to the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R), the prevalence of BED was 6.5%. As for the prevalence of BPD, 14.0% exceeded the clinical cut-off score on the Self-Harm Inventory (SHI), 14.0% exceeded the clinical cut-off score on the borderline personality scale of the Personality Diagnostic Questionnaire-4 (PDQ-4), and 7.4% exceeded the clinical cut-off score on the McLean Screening Inventory for Borderline Personality Disorder (MSI-BPD). Overall, 24.8% of the sample exceeded the clinical cut-off on at least one measure of BPD whereas only 3.3% exceeded the clinical cut-off on all three measures. In addition, there was a significant inverse relationship between the discrepancy between highest and lowest adult body mass index, and scores on the PDQ-4 and the MSI-BPD. The authors discuss the implications of these findings.

Abstract
In this study, we examined the prevalence of traumatic childhood experiences as well as the quality of parental caretaking among 121 individuals (85.9% of which were women) seeking surgical treatment for obesity (mean body mass index of 47.2). Among this sample, 43.0% reported emotional abuse, 39.0% the witnessing of violence, 19.0% sexual abuse, 17.4% physical abuse, and 9.1% physical neglect. While the overall quality of parental caretaking was skewed toward a positive rating, those respondents who indicated each form of childhood trauma rated the quality of parental caretaking lower than did those without that specific form of abuse. The authors discuss the implications of these findings.

Abstract
OBJECTIVE Research on the accuracy of self-reported weight has indicated that the degree of misreporting (underestimating) weight is associated with increasing weight but is variable across patient groups. We examined the degree of discrepancy between actual and self-reported BMI in severely obese bariatric surgery candidates, and whether the degree of accuracy varied by race and by eating-related and psychological factors. RESEARCH METHODS AND PROCEDURES Participants were 179 obese female gastric bypass surgery candidates (31 black, 22 Hispanic, 126 white) who were asked to self-report height and weight as part of a larger assessment battery. Actual height and weight were then measured and a discrepancy score was generated (actual BMI - reported BMI). RESULTS In this group of severely obese patients, degree of misreporting was unrelated to BMI. The race groups did not differ in actual or self-reported BMI but differed significantly in the degree of misestimation between self-reported and actual BMI. Post hoc tests indicated that black women underestimated their BMI significantly more than white women; Hispanic women did not differ from the other race groups. No eating-related or psychological variables assessed predicted percentage discrepancy; however, the accuracy in self-reported weight was related to history of weight cycling. DISCUSSION Overall, obese bariatric surgery candidates were accurate in self-report of weight, although the degree of accuracy differed by race and weight cycling history.

Abstract
BACKGROUND Weight-related problems, including obesity, eating disorders, and disordered eating, are major public health problems in adolescents. The identification of shared risk and protective factors for these problems can guide the development of relevant interventions to a broad spectrum of weight-related problems. This paper examines the prevalence and co-occurrence of overweight, binge eating, and extreme weight-control behaviors (vomiting, diet pills, laxatives, and diuretics) in adolescents and identifies shared risk and protective factors from within the socioenvironmental, personal, and behavioral domains for these three adverse weight-related outcomes. METHODS Data were collected at Time 1 (1998-1999) and Time 2 (2003-2004) on 2516 adolescents participating in Project EAT (Eating Among Teens). Data were analyzed in 2006-2007. RESULTS Weight-related problems were identified in 44% of the female subjects and 29% of the male subjects. About 40% of overweight girls and 20% of overweight boys engaged in at least one of the disordered eating behaviors (binge eating and/or extreme weight control). Weight-teasing by family, personal weight concerns, and dieting/unhealthy weight-control behaviors strongly and consistently predicted overweight status, binge eating, and extreme weight-control behaviors after 5 years. Family meals, regular meal patterns, and media exposure to messages about weight loss were also associated with weight-related outcomes, although the strength and consistency of associations differed across outcomes and gender. CONCLUSIONS Weight-specific socioenvironmental, personal, and behavioral variables are strong and consistent predictors of overweight status, binge eating, and extreme weight-control behaviors later in adolescence. These findings support the need for research to determine if decreasing weight-related social pressures, personal weight concerns, and unhealthy weight-control behaviors can contribute to reductions in obesity in children and adolescents.

Abstract
OBJECTIVE The prevalence of night eating syndrome (NES), binge eating disorder (BED), and bulimia nervosa (BN) and the general experience of food cravings were examined in 88 obese urban African American women. METHOD Participants were administered The Questionnaire on Eating and Weight Patterns-R, the Night Eating Syndrome Questionnaire, and the State and Trait Food Cravings Questionnaire, Trait version (FCQ-T). RESULTS Twenty-eight percent reported symptoms of eating disorders (18.9% NES, 6.4% recurrent binge eating, 2.2% both NES and recurrent binge eating). Those reporting disordered eating had significantly higher total FCQ-T scores than those not reporting disordered eating. Persons endorsing recurrent binge eating had the highest mean score, followed by those reporting NES. Those who identified themselves as binge eaters and night eaters were not significantly different from each other, but both groups were significantly different than the no eating disorder symptoms group on various subscales of the FCQ-T. DISCUSSION Obese African American women report significant levels of NES and binge eating which may contribute to the development and/ or maintenance of obesity.

Abstract
BACKGROUND & AIMS It is unclear whether weight loss with the noradrenergic (norepinephrine) and serotonergic (5-hydroxytryptamine) reuptake inhibitor, sibutramine, is associated with altered stomach functions and whether genetics influence treatment response. METHODS Forty-eight overweight and obese but otherwise healthy participants were randomized to placebo or sibutramine (15 mg/day for 12 weeks). At baseline and posttreatment we measured the following: gastric emptying for solids and liquids by scintigraphy, gastric volumes by single-photon emission computed tomography, maximum tolerated volume and 30-minute postnutrient challenge symptoms, and selected gastrointestinal hormones. All participants received structured behavior therapy for weight management. The influence of candidate gene polymorphisms involved in norepinephrine and 5-hydroxytryptamine or receptor function (phenylethanolamine N-methyltransferase, guanine nucleotide binding protein beta polypeptide 3, alpha2A adrenoreceptor, and solute carrier family 6 [neurotransmitter transporter, serotonin] member 4 [homo sapiens] [SLC6A4]) on weight loss and gastric functions was evaluated. RESULTS The overall average weight loss posttreatment was 5.4 +/- 0.8 (SEM) kg with sibutramine and 0.9 +/- 0.9 kg with placebo (P < .001). The sibutramine group showed significant retardation in gastric emptying of solids (P = .03), reduced maximum tolerated volume (P = .03), and increased postprandial peptide YY compared with the placebo group. Obese females showed greater effects of sibutramine on weight loss and gastric emptying of solids and liquids. Gastric volumes and postchallenge symptoms were not significantly different in the 2 treatment groups. The LS/SS genotype of the promoter for SLC6A4 was associated with enhanced weight loss with sibutramine. CONCLUSIONS Weight reduction with sibutramine is associated with altered gastric functions and increased peptide YY and is significantly associated with SLC6A4 genotype. The role of genetic variation in SLC6A4 on weight loss in response to sibutramine deserves further study.

Abstract
BACKGROUND The impact of presurgical eating patterns on postoperative outcomes is poorly understood. The results of previous studies are mixed regarding the impact of presurgical binge eating on weight loss after surgery. However, many patients describe other maladaptive eating patterns prior to surgery, such as eating in response to emotions. The goals of this study were to describe presurgical emotional eating patterns in morbidly obese individuals, determine whether these individuals were binge eaters, and assess the effect of this eating behavior on weight loss after surgery. METHODS Prior to surgery, 144 Roux-en-Y gastric bypass (RYGBP) patients completed the Questionnaire of Eating and Weight Patterns (QEWP) or QEWP-Revised (QEWP-R) and the Emotional Eating Scale to assess eating patterns prior to surgery. Their eating behavior, levels of depression, and weight were assessed after surgery. RESULTS High emotional eaters tended to have higher levels of depression, binge eating, and eating in response to external cues than low emotional eaters prior to surgery. However, there appeared to be a distinct group of individuals who were high emotional eaters but who did not engage in binge eating. At a mean of 8 months after surgery, High Emotional Eaters and Low Emotional Eaters were indistinguishable on these subscales and there were no differences in weight lost. CONCLUSIONS RYGBP has an equally positive impact on eating behavior and weight loss for both High Emotional Eaters and Low Emotional Eaters. Further replication is needed with longer follow-up times and larger samples.

Abstract
Clinical binge eating runs a protracted course. The etiology of binge eating remains perplexing in part because, in humans, it is difficult to isolate and assess the independent and aggregate impact of various contributing variables. Using rats, we found that footshock stress and a history of caloric restriction (S+R), combine synergistically to induce binge eating. Stress and dieting are also strong antecedents and relapse factors in human eating disorders. Here we report further behavioral and physiological parallels to human binge eating. Like the protracted course of human binge eating, young female Sprague-Dawley rats continued to binge eat after 23 restriction/stress cycles (7 months) and this despite experiencing no significant weight loss during the restriction phases. Stress alone reduced adiposity by 35% (p<0.001) but S+R rats had no significant fat loss. An endocrine profile of normal plasma leptin and insulin levels but marked elevation of plasma corticosterone levels was found only in the binge-eating (S+R) rats (p<0.01), also paralleling endocrine profiles reported in clinical binge-eating studies. These behavioral and physiological similarities between this animal model and clinical binge eating increase its utility in understanding binge eating. Importantly, our findings also highlight the stubborn nature of binge eating: once a critical experience with dieting and stress is experienced, little if any further weight loss or food restriction is necessary to sustain it.

Abstract
OBJECTIVE To examine the self-reported sequence and timing of onset of overweight, binge eating, and dieting in adult patients diagnosed with binge eating disorder (BED). METHOD Participants were 284 treatment-seeking adults (73 men and 211 women) who met DSM-IV research criteria for BED. Patients were interviewed with structured diagnostic interviews and were queried regarding history of overweight, dieting, and binge eating behaviors. Questionnaires were also administered to assess current eating disturbances, body dissatisfaction, and general functioning. Participants were classified as Overweight First, Binge First, or Diet First, and the three groups were compared on developmental sequence and using the battery of measures. RESULTS Sixty-three percent of the 284 participants reported becoming overweight prior to the onset of dieting or binge eating. Participants who reported they were overweight first had significantly greater BMI at the time of assessment. The 16% of the participants who reported binge eating first were significantly younger at the onset of BED diagnosis and reported significantly less dietary restraint. Onset order differed significantly by gender; proportionally more women (25%) than men (11%) reported that dieting preceded overweight or binge eating. CONCLUSION Weight problems preceded dieting and binge eating behaviors for a majority of treatment-seeking overweight participants diagnosed with BED.

Abstract
OBJECTIVE We examined the prevalence, persistence, secular and longitudinal trends, and predictors of steroid use in a diverse sample of adolescents. PARTICIPANTS AND METHODS Data are from Project EAT-II (Eating Among Teens), a 5-year longitudinal study of eating, activity, weight, and related variables in 2516 middle and high school students. Data were collected in 1999 (time 1) and 2004 (time 2). RESULTS Approximately 1.5% of adolescents reported steroid use at time 2. Use differed by ethnicity but not socioeconomic status. Steroid use was not stable across time, although the risk of use at time 2 was higher for girls and (marginally) for boys who used steroids at time 1. No secular trends were noted in middle adolescents' steroid use between 1999 and 2004. Developmentally, steroid use decreased as adolescents grew older. Predictors of use for male adolescents included wanting to weigh more and reporting higher use of healthy weight-control behaviors. Female time 2 steroid users had higher BMIs and were less satisfied with their weight, had poorer nutrition knowledge and concern for health, and were marginally more likely to have participated in weight-related sports at time 1. CONCLUSIONS The prevalence of steroid use in adolescents was low but of concern. Although use was not persistent over 5 years, time 1 use was a risk factor for time 2 use in female adolescents. There was no change in the prevalence of steroid use by middle adolescents between 1999 and 2004 despite a great deal of public interest in steroids during this time period. Steroid use decreased as adolescents grew older. Weight-related variables predicted adolescents' steroid use 5 years later, and health and nutrition knowledge and concern and (marginally) participation in weight-related sports further predicted use in female adolescents. These findings suggest that early preventive efforts may be most useful.

Abstract
OBJECTIVE The current study examined body image concerns and eating disordered behaviors in a community sample of Black and Hispanic women. In addition, this study explored whether there are ethnic differences in the correlates or in the prediction of body image concerns. METHOD Participants were 120 (67 Black and 53 Hispanic) women who responded to advertisements to participate in a study of women and health. Participants completed a battery of established self-report measures to assess body image, eating disordered behaviors, and associated psychological domains. RESULTS Black and Hispanic women did not differ significantly in their self-reports of body image, eating disordered behaviors, or associated psychological measures. Comparisons performed separately within both ethnic groups revealed significant differences by weight status, with a general graded patterning of greater concerns in obese than overweight than average weight groups. In terms of predicting body image, multiple regression analyses testing a number of variables, including BMI, performed separately for Black and Hispanic women revealed that eating concern and depressive affect were significant predictors of body image concern for both groups. DISCUSSION Overall, Black and Hispanic women differed little in their self-reports of body image, eating-disordered features, and depressive affect. Higher weight was associated with a general pattern of increased body image concerns and features of eating disorders in both groups and with binge eating in Black women. Eating concerns and depressive affect emerged as significant independent predictors of body image for both ethnic groups.

Abstract
OBJECTIVE The purpose of this study was to evaluate the association between frequent reading of magazine articles about dieting/weight loss and weight-control behaviors and psychological outcomes 5 years later in a sample of adolescents. PARTICIPANTS AND METHODS Data are from Project EAT (Eating Among Teens), a 5-year longitudinal study of eating, activity, weight, and related variables in 2516 middle and high school students. In 1999 (time 1), participants completed surveys and had their height and weight measured. In 2004 (time 2), participants were resurveyed. RESULTS For female adolescents, the frequency of healthy, unhealthy, and extreme weight-control behaviors increased with increasing magazine reading after adjusting for time 1 weight-control behaviors, weight importance, BMI, and demographic covariates. The odds of engaging in unhealthy weight-control behaviors (such as fasting, skipping meals, and smoking more cigarettes) were twice as high for the most frequent readers compared with those who did not read magazine articles about dieting and weight loss. The odds of using extreme weight-control behaviors (such as vomiting or using laxatives) were 3 times higher in the highest frequency readers compared with those who did not read such magazines. There were no significant associations for either weight-control behaviors or psychological outcomes for male adolescents. CONCLUSIONS Frequent reading of magazine articles about dieting/weight loss strongly predicted unhealthy weight-control behaviors in adolescent girls, but not boys, 5 years later. Findings from this study, in conjunction with findings from previous studies, suggest a need for interventions aimed at reducing exposure to, and the importance placed on, media messages regarding dieting and weight loss.

Abstract
BACKGROUND & AIMS Peptide YY (PYY) levels are reported to be decreased in obesity. The relation between gastric functions, satiation, and gut hormones in obesity is incompletely understood. The aim of this study was to compare gastric volumes, emptying, maximum tolerated volumes, postchallenge symptoms, and selected gut hormones in normal, overweight, or obese healthy volunteers. METHODS In 73 nonbulimic normal, overweight, or obese participants weighing less than 137 kg, we measured gastric emptying of solids and liquids by scintigraphy (gastric emptying half-time [GE t(1/2)]); gastric volumes by single-photon emission computed tomography; maximum tolerated volumes and symptoms by satiation test; and plasma leptin, ghrelin, insulin, glucagon-like peptide 1, and PYY levels. Groups were compared using 1-way analysis of covariance adjusted for sex. Univariate associations among measured responses were assessed using Spearman correlations. Multiple linear regression models, adjusting for weight and sex, assessed the independent ability of gastric functions and hormones to predict satiation volume. RESULTS Obese and overweight subjects had significantly lower postprandial gastric volumes, higher fasting and postprandial insulin and leptin levels, and lower fasting ghrelin and lower postprandial reduction in ghrelin levels. PYY levels were not different in obese or overweight subjects compared with controls. The GE t(1/2) was correlated inversely with postprandial PYY; increased body weight was associated with faster GE t(1/2) of solids (r(s) = 0.33, P = .005) and liquids (r(s) = 0.24, P = .04). Postprandial changes in gastric volume and PYY were independent predictors of satiation (both P = .01). CONCLUSIONS Overweight or obesity are associated with lower postprandial gastric volumes and normal PYY levels. Gastric emptying influences postprandial PYY levels. Postprandial PYY and gastric volume independently predict satiation volume in nonbulimic people across a wide body mass index range.

Abstract
BACKGROUND A history of sexual abuse is associated with a range of psychosocial difficulties and health risk behaviors in the general population. Sexual abuse also appears to be a risk factor for the development of obesity. Little is known, however, about the prevalence and psychosocial correlates of sexual abuse among persons with extreme obesity who seek bariatric surgery. METHODS Questionnaire data were collected from 567 individuals with extreme obesity who presented for bariatric surgery. Those with and without a self-reported history of sexual abuse were compared on several psychosocial variables. RESULTS Sixteen percent of the surgery candidates (17.0% of women and 11.5% of men) reported a history of sexual abuse. Those who reported a history of sexual abuse were more likely to report previous emotional difficulties, as well as a personal and family history of substance abuse. They also were significantly more likely to meet the criteria for binge eating disorder, as determined from self-report responses to the Questionnaire on Eating and Weight Patterns, compared with those without a self-reported history of sexual abuse. In addition, those who reported a history of sexual abuse were more likely to report both current and previous psychiatric treatment than were those who denied a history of abuse. CONCLUSION A significant minority of bariatric surgery candidates reported a history of sexual abuse. Among these individuals, a history of sexual abuse was associated with both current and past psychiatric problems and treatment. The relationship of these variables to postoperative outcomes, however, is unknown.

Abstract
The purpose of the present study was to evaluate the clinical usefulness of the Portuguese version of the Binge Eating Scale (BES) to assess binge eating disorder (BED) in a clinical sample. The BES is a self-reported instrument developed to identify binge eaters within the obese population. The scale, at the cutoff point of 17, was compared with the Structured Clinical Interview for the DSM-IV-Patient version (SCID-I/P). It was administered to 178 obese Brazilian women, aged 18 to 60 years, seeking treatment for obesity at an outpatient clinic. To assess the test-retest reliability, 121 individuals filled the instrument again 15 days later. The Portuguese version of BES showed a sensitivity of 97.8%, a specificity of 47.7%, a positive predictive value of 66.7% and a negative predictive value of 95.3%. The test-retest reliability, measured by kappa statistics, was 0.66. Cronbach's alpha was 0.89. These results suggest that the BES is valid as a screening instrument for BED in obese Brazilian women seeking treatment for obesity.

Abstract
AIM In this randomized, double-blind, placebo-controlled study, the effect of sibutramine and cognitive-behavioural weight loss (cognitive-BWL) treatment was assessed in obese subjects with and without subclinical binge eating disorder (sBED). METHODS Seventy-three obese participants were recruited from the community, 29 with and 44 without sBED. Subjects were randomly assigned to a 16-week treatment with either sibutramine or placebo while simultaneously participating in a cognitive-behavioural weight loss treatment. RESULTS Intent-to-treat analysis showed moderate weight loss after treatment in all subject groups. Treatment with BWL programs and sibutramine leads to a higher weight loss in all subjects compared with that in patients who had undergone BWL programs alone. Subjects with sBED significantly reduced their binge episodes during treatment, but with no augmenting effect of sibutramine. DISCUSSION Our results yield further evidence that sBED is associated with characteristics comparable with full-syndrome BED, significantly differing from those of obesity alone. These findings call for a systematic assessment of eating behaviour before starting obesity treatment.

Abstract
This study compared two self-report methods for assessing binge eating in severely obese bariatric surgery candidates. Participants were 249 gastric bypass candidates who completed the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R) and the Eating Disorder Examination-Questionnaire (EDE-Q) prior to surgery. Participants were classified by binge eating status (i.e., no or recurrent binge eating) with each of the measures. The degree of agreement was examined, as well as the relationship between binge eating and measures of convergent validity. The two measures identified a similar number of patients with recurrent binge eating (i.e., at least 1 binge/week); however, overlap was modest (kappa=.26). Agreement on twice weekly binge eating was poor (kappa=.05). The QEWP-R and EDE-Q both identified clinically meaningful groups of binge eaters. The EDE-Q appeared to differentiate between non/infrequent bingers and recurrent bingers better than the QEWP-R, based on measures of convergent validity. In addition, the EDE-Q demonstrated an advantage because it identified binge eaters with elevated weight and shape overconcern. Using the self-report measures concurrently did not improve identification of binge eating in this study. More work is needed to determine the construct validity and clinical utility of these measures with gastric bypass patients.

Abstract
OBJECTIVE Limited data suggest that psychological factors, including binge eating, dieting, and depressive symptoms, may predispose children to excessive weight gain. We investigated the relationship between baseline psychological measures and changes in body fat (measured with dual-energy x-ray absorptiometry) over time among children thought to be at high risk for adult obesity. METHODS A cohort study of a convenience sample of children (age: 6-12 years) recruited from Washington, DC, and its suburbs was performed. Subjects were selected to be at increased risk for adult obesity, either because they were overweight when first examined or because their parents were overweight. Children completed questionnaires at baseline that assessed dieting, binge eating, disordered eating attitudes, and depressive symptoms; they underwent measurements of body fat mass at baseline and annually for an average of 4.2 years (SD: 1.8 years). RESULTS Five hundred sixty-eight measurements were obtained between July 1996 and December 2004, for 146 children. Both binge eating and dieting predicted increases in body fat. Neither depressive symptoms nor disturbed eating attitudes served as significant predictors. Children who reported binge eating gained, on average, 15% more fat mass, compared with children who did not report binge eating. CONCLUSIONS Children's reports of binge eating and dieting were salient predictors of gains in fat mass during middle childhood among children at high risk for adult obesity. Interventions targeting disordered eating behaviors may be useful in preventing excessive fat gain in this high-risk group.

Abstract
OBJECTIVE To assess the prevalence of night eating syndrome (NES) and binge eating disorder (BED) and their related behavioral and psychological correlates in persons who sought bariatric surgery. RESEARCH METHODS AND PROCEDURES A consecutive series of 215 persons with extreme obesity (82% women, 70% European American) completed the Weight and Lifestyle Inventory and a semistructured interview as part of a pre-surgery behavioral/psychological assessment. Diagnoses for NES and BED were based on graded diagnostic criteria. RESULTS Percentages of participants who met diagnostic criteria for NES by interview were 1.9% for the strictest definition and 8.9% across all definitions of NES. After interview, full DSM-TR criteria for BED were met by 4.2%; an additional 1.4% reported binge eating at least once per week. Self-reported prevalence of NES and BED were higher. Those with NES or BED had significantly more symptoms of depression and a greater history of psychological complications than the remaining sample. DISCUSSION The prevalence rates of NES and BED among this population of bariatric surgery candidates were lower than expected based on previous reports. Findings and hypotheses regarding lowered prevalence rates are discussed.

Abstract
OBJECTIVE To summarize the self-reported eating behaviors of persons seeking bariatric surgery and to provide reliability data for a clinical instrument that assesses those eating behaviors. RESEARCH METHODS AND PROCEDURES Adults (552) with extreme obesity (mean +/- standard deviation BMI = 52.4 +/- 10.1 kg/m(2)) completed the Weight and Lifestyle Inventory (WALI) before undergoing bariatric surgery. The WALI is a self-report instrument that includes 24 items that assess the eating behaviors to which respondents attribute their excess weight. These items were entered into a principal components analysis with promax rotation. Relationships of factor scores to demographic and psychosocial variables were examined. Test-retest reliability data were obtained from a smaller sample (n = 58) of less obese participants (BMI = 34.4 +/- 4.0 kg/m(2)) who completed the WALI twice within 2 weeks, before beginning a non-surgical weight loss program. RESULTS The principal components analysis yielded five factors with acceptable internal consistency and test-retest reliability. These included: eating in response to negative affect, eating in response to positive affect and social cues, general overeating and impaired appetite regulation, overeating at early meals, and snacking. Each factor was related to symptoms of binge eating disorder, and every factor except the second one was associated with depressive symptoms. Factor scores were unrelated or weakly associated with demographic characteristics. DISCUSSION The eating behaviors of persons seeking bariatric surgery can be assessed reliably and parsimoniously with the WALI. The predictive utility of the factors obtained in this study remains to be examined.

Abstract
This paper discusses the behavioral evaluation of patients who seek bariatric surgery and the psychosocial complications most frequently observed in these individuals. The effects of such complications on surgical outcome are briefly examined, as is the challenge of predicting therapeutic response on the basis of preoperative variables. The paper concludes with a description of the goals and methods of a behavioral assessment used at the University of Pennsylvania. This evaluation includes the use of the Weight and Lifestyle Inventory, a questionnaire that guides our interview with patients.

Abstract
The aim of this cross-sectional descriptive study of 194 Swedish men and women seeking non-surgical weight-loss treatment was to investigate the presence of eating disorders and binge eating symptoms and to compare these two groups of patients with a group without eating disorder- or binge eating symptoms. The groups were compared in regard to co-morbid psychopathology, Health Related Quality of Life (HRQL) and anthropometric data. Of the total sample, 9.8% fulfilled criteria for any eating disorder. An additional 7.2% indicated binge eating symptoms without having an eating disorder. The three groups were significantly different in regard to psychopathology scales and most HRQL items. Eating disorders and binge eating symptoms are common among patients seeking non-surgical weight-loss treatments in Sweden and both groups showed elevated levels of co-morbid psychopathology and lower HRQL compared to patients without disordered eating. These findings point to the importance of assessing the full range of eating disorder symptoms and disorders as well as HRQL and co-morbid psychopathology before weight-loss treatment, as these factors might affect treatment outcome.

Abstract
Functional neuroimaging was employed to study 10 obese and 10 lean healthy young right-handed women, divided equally into binge and non-binge eaters. Subjects were presented with visual and auditory stimuli of binge type foods, non-binge type foods, and non-food stimuli in the fMRI scanner. Brain areas activated by both the visual and auditory stimuli across all individual subjects within a particular group was observed only for the binge food stimuli in the obese binge eaters, in the right premotor area, involved in planning of motor behavior. For four of the five obese binge eaters, the activation was in the ventral premotor cortex adjacent to the oral region, and may reflect past or concurrent motor planning about eating binge foods. Because a random effects group analysis has not yet been completed, this should be considered a preliminary report.

Abstract
OBJECTIVE: The present paper describes the validation of the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R) designed for the diagnosis of binge eating disorder (BED) and sub-clinical binge eating. METHODS: 89 overweight women seeking treatment for binge eating and/or obesity were assessed with the Portuguese version of the Questionnaire of Eating and Weight Patterns and were, subsequently, interviewed with the eating disorders module of the Structured Clinical Interview for DSM-IV (SCID-I/P). Rates of binge eating disorder and sub-clinical cases of binge eating obtained with the Questionnaire on Eating and Weight Patterns-Revised were then compared to those obtained with the Structured Clinical Interview for DSM-IV. RESULTS: In the identification of binge eating, irrespective of the presence of all criteria for binge eating disorder the QEWP-R Questionnaire on Eating and Weight Patterns-Revised yielded a sensitivity value of 0.88, a specificity value of 0.63 and a positive predictive value of 0.825. Rates for the identification of the full syndrome of binge eating disorder were: sensitivity value of 0.548, a specificity value of 0.8 and a positive predictive value of 0.793. CONCLUSIONS: The Questionnaire on Eating and Weight Patterns-Revised can be useful in a first-step screening procedure to identify probable cases of binge eating. It can be useful as a screening tool and as a first step of clinical assessment of patients seeking treatment for binge eating and/or obesity.

Abstract
Bariatric surgery has become an increasingly popular treatment option for individuals with extreme obesity (defined as a BMI > or = 40 kg/m2) or those with less severe obesity accompanied by significant comorbidities. Sustained postoperative weight loss and improvements in obesity-related health problems make bariatric surgery the most effective treatment for this population. Nevertheless, most experts agree that psychosocial and behavioral factors contribute to successful postoperative outcomes. This paper reviews the literature on the preoperative psychosocial status, eating behaviors, and quality of life of patients who seek bariatric surgery. In addition, the paper examines studies that investigated changes in these factors postoperatively. The review concludes with an agenda for future research in this area.

Abstract
The aim of this study (duration: 12 months) was to compare different integrated therapeutic approaches for the therapy of Binge Eating Disorder (BED). A sample of 65 female severely obese BED was randomly divided into 3 groups: the first one was treated by Cognitive-Behavioural Therapy (CBT) alone; the second one was treated by SSRI antidepressant therapy (fluoxetine) alone; the remaining was treated by a combination of CBT plus fluoxetine. All groups received group nutritional training and individual dietary counselling. The initial fluoxetine dose (20 mg/day) was adjusted (up to 60 mg/day) according to frequency of binge eating. During the first 4 weeks, all subjects underwent an in-patient dietary treatment aimed to achieve at least a 5% weight loss, which was continued during the out-patient treatment phase. At the beginning and at the end of the therapy the patients were evaluated by the Minnesota Multiphasic Personality - 2 and by the Eating Disorder Inventory - 2. The results showed that the two groups which underwent psychotherapy resulted in a better outcome - in terms of number of bingeing episodes, maintenance of weight loss reduction from baseline and psychological well being - than the group treated with pharmacological therapy alone. Finally, the study underlines the importance of a multidisciplinary approach to the treatment of Binge Eating Disorder.

Abstract
Binge-eating disorder (BED), characterized by binge meals without purging afterward, is found in about 30% of obese individuals seeking treatment. The study objective was to ascertain abnormalities in hormones influencing appetite in BED, especially ghrelin, an appetite-stimulating peptide, which was expected to be elevated. Measurements were made of plasma insulin, leptin, glucagon, cholecystokinin, and ghrelin, as well as glucose following an overnight 12-h fast, prior to and after ingestion (from 0 to 5 min) of a nutritionally complete liquid meal (1254 kJ) at 0830 h, at -15, 0, 5, 15, 30, 60, 90, and 120 min. Appetite ratings including hunger and fullness were also obtained. An acetaminophen tracer was used to assess gastric emptying rate. Three groups of comparably obese women (BMI = 35.9 +/- 5.5; % body fat = 44.9 +/- 4.7) participated: 12 nonbinge eating normals (NB), 14 subthreshold BED, and 11 BED. The BED subjects, compared to NB subjects, had lower baseline ghrelin concentrations prior to the meal, a lower area under the curve (AUC), with lower levels at 5, 15, 30, 90, and 120 min, and a smaller decline in ghrelin postmeal (all P < 0.03). The other blood values did not differ among groups, and neither did gastric emptying rate nor ratings of fullness. The BED subjects were then randomly assigned to treatment with cognitive-behavior therapy and diet (n = 5) or to a wait-list control (n = 4). Baseline ghrelin (P = 0.01) and AUC increased (P = 0.02), across both conditions, in which most subjects (7 of 9) stopped binge eating. The lower fasting and postmeal plasma ghrelin levels in BED are consistent with lower ghrelin levels in obese compared to lean individuals and suggests downregulation by binge eating.

Abstract
OBJECTIVE The primary purpose was to examine 2-y effects of weight change on personality traits in severely obese subjects treated conventionally or surgically. We also assessed differences between the severely obese patients and a primarily normal-weight reference group. METHOD Personality traits were assessed using 7 of 15 scales from the Karolinska Scales of Personality (KSP): Somatic Anxiety, Muscular Tension, Psychasthenia, Psychic Anxiety, Monotony Avoidance, Impulsiveness, and Irritability. A total of 1380 surgical candidates, 1241 conventionally treated patients and 1135 subjects from the SOS (Swedish Obese Subjects) reference study, representing the general population, completed the KSP. Data presented in this study were gathered twice from the patients (prior to treatment and after 2 y) and once from the reference subjects. Significance tests and effect sizes (ES) were calculated. RESULTS At baseline, the obese were characterised as more anxiety prone, impulsive, irritable and less monotony avoiding than the reference group; surgery patients more so than the conventionally treated. At follow-up, it was found that anxiety proneness decreased and Monotony Avoidance increased with increasing weight loss. The conventionally treated were, on average, weight stable and, hence, only a small decrease was noted regarding Somatic Anxiety. The surgery group lost on average 28 kg, and differences between surgically treated and the reference group decreased on all scales except Impulsiveness, which remained unchanged. The largest improvement was in relation to Psychasthenia. CONCLUSIONS Weight reduction maintained for 2 y was associated with changes on practically all personality traits in proportion to the magnitude of weight loss. In particular, Psychasthenia seemed to be alleviated, while Impulsiveness was unaffected.

Abstract
OBJECTIVE Increased basal cortisol levels have been found in bulimia nervosa. After stress, increased cortisol levels have been associated with increased food intake in healthy women. Therefore, we assessed cortisol, hunger, and desire to binge eat after a cold pressor test (CPT) among women with binge eating disorder (BED). METHODS Twenty-two obese (body mass index [BMI] = 36.7 +/- 6.5 SD) females (11 non-BED, 11 BED) completed the Zung depression scale and underwent the CPT, hand submerged in ice water for 2 minutes. Over 60 minutes, periodic ratings of hunger and desire to binge eat were obtained, just before blood draws for cortisol, as well as insulin. On a separate day, participants had a 1-mg oral dexamethasone suppression test (DST). RESULTS The BED group had higher depression scores than the non-BED (p = .04), but depression was not a significant covariate for the cortisol response or to DST. After controlling for contraceptive use (n = 3), the BED group had higher basal cortisol than the non-BED group (p = .03), but cortisol did not differ after DST (p = .40). The BED group had nearly significant greater cortisol AUC after the CPT (p = .057) after controlling for insulin AUC and contraceptive use (p = .057). The BED group also had greater AUC for hunger (p = .03) and desire to binge eat (p = .02) after the CPT. CONCLUSION These findings support our hypothesis of a hyperactive HPA-axis in BED, which may contribute to greater hunger and binge eating.

Abstract
The worldwide increase in the incidence of obesity is a consequence of a positive energy balance, with energy intake exceeding expenditure. The signalling systems that underlie appetite control are complex, and the present review highlights our current understanding of key components of these systems. The pattern of eating in obesity ranges from over-eating associated with binge-eating disorder to the absence of binge-eating. The present review also examines evidence of defects in signalling that differentiate these sub-types. The signalling network underlying hunger, satiety and metabolic status includes the hormonal signals leptin and insulin from energy stores, and cholecystokinin, glucagon-like peptide-1, ghrelin and peptide YY3-36 from the gastrointestinal tract, as well as neuronal influences via the vagus nerve from the digestive tract. This information is routed to specific nuclei of the hypothalamus and brain stem, such as the arcuate nucleus and the solitary tract nucleus respectively, which in turn activate distinct neuronal networks. Of the numerous neuropeptides in the brain, neuropeptide Y, agouti gene-related peptide and orexin stimulate appetite, while melanocortins and alpha-melanocortin-stimulating hormone are involved in satiety. Of the many gastrointestinal peptides, ghrelin is the only appetite-stimulating hormone, whereas cholecystokinin, glucagon-like peptide-1 and peptide YY3-36 promote satiety. Adipose tissue provides signals about energy storage levels to the brain through leptin, adiponectin and resistin. Binge-eating has been related to a dysfunction in the ghrelin signalling system. Moreover, changes in gastric capacity are observed, and as gastric capacity is increased, so satiety signals arising from gastric and post-gastric cues are reduced. Understanding the host of neuropeptides and peptide hormones through which hunger and satiety operate should lead to novel therapeutic approaches for obesity; potential therapeutic strategies are highlighted.

Abstract
OBJECTIVE To investigate the characteristics and prevalence of binge eating among overweight Taiwanese and to determine the effect of binge eating on outcome of weight loss treatment. METHODS One hundred and eighty-nine participants in a 12-week traditional weight-reduction program were classified on the basis of the Bulimic Investigation Test, Edinburgh (BITE) scores into binge eaters (>/=20), subthreshold binge eaters (10-19), and nonbinge eaters (0-9). RESULTS This study found a 15.9% prevalence of binge eating. The binge-eating groups (binge eaters and subthreshold binge eaters) were younger, had an earlier onset of obesity, and more psychological distress than nonbinge eaters. Differences in obesity treatment weight loss among binge eaters, subthreshold binge eaters, or nonbingers by last observation carried forward (LOCF) method were not significant. At the end of treatment, the subthreshold binge eaters had the greatest weight loss. Although their binge eating and mood significantly improved, binge eaters and subthreshold binge eaters still had significant pathology in eating behaviors at completion of the program. CONCLUSION Alternative treatment strategies focusing on disordered eating behaviors are needed to supplement standard dietary management of overweight treatment-seeking binge eaters.

Abstract
BACKGROUND Some investigators fear that dieting may precipitate binge eating and other adverse behavioral consequences. OBJECTIVE The objective of the study was to examine whether dieting would elicit binge eating and mood disturbance in individuals free of these complications before treatment. DESIGN A total of 123 obese women were randomly assigned to 1) a 1000 kcal/d diet that included 4 servings/d of a liquid meal replacement (MR); 2) a 1200-1500 kcal/d balanced deficit diet (BDD) of conventional foods; or 3) a nondieting (ND) approach that discouraged energy restriction. All women attended weekly group sessions for 20 wk and biweekly sessions from week 20 to week 40. RESULTS At week 20, participants in the MR, BDD, and ND groups lost 12.1 +/- 6.7%, 7.8 +/- 6.0%, and 0.1 +/- 2.4% of initial weight, respectively (P < 0.001). During the first 20 wk, there were no significant differences among groups in the number of persons who had objective binge episodes or in reports of hunger or dietary disinhibition. Symptoms of depression decreased significantly more (P < 0.001) in the MR and BDD groups than in ND participants. At week 28, significantly more (P < 0.003) cases of binge eating were observed in MR participants than in the 2 other groups. No differences, however, were observed between groups at weeks 40 or 65 (a follow-up visit). At no time did any participant meet criteria for binge-eating disorder. CONCLUSION Concerns about possible adverse behavioral consequences of dieting should not dissuade primary care providers from recommending modest energy restriction to obese individuals.

Abstract
In the last several decades, research on the eating disorders has yielded important new knowledge, especially regarding the clinical characteristics and the treatment of individuals with Bulimia Nervosa. Challenging issues now confronting the field include how the eating disorders should be categorized, what factors underlie their development and persistence, and how they are best treated. New efforts based on the analysis of genetic factors, on the use of brain imaging and on the detailed analysis of behavioral disturbances hold promise for significantly advancing our understanding of these disorders in the next decade.

Abstract
OBJECTIVE Although binge eating has been recognized as a clinically relevant behavior among the obese for more than four decades, the concept of binge eating disorder (BED) as a distinct psychiatric diagnosis is of much more recent origin. This article presents four ways of conceptualizing BED: a distinct disorder in its own right, as a variant of bulimia nervosa, as a useful behavioral subtype of obesity, and as a behavior that reflects psychopathology among the obese. It also summarizes the evidence supporting and disconfirming each model. METHOD The literature subsequent to the development of DSM-IV regarding the reliability and validity of BED and related conditions was reviewed selectively. RESULTS The preponderance of the evidence suggests that BED differs importantly from purging bulimia nervosa and that BED is not a strikingly useful behavioral subtype of obesity. DISCUSSION Further study is needed to definitively determine the validity of BED as a distinct eating disorder.

Abstract
OBJECTIVE Current controversy exists regarding the status of binge eating disorder (BED) as a diagnostic entity. A critique of the literature is provided to address the question of whether BED represents a clinically significant syndrome. METHOD The scientific evidence is considered through addressing five questions that are key in evaluating the clinical utility of any mental disorder. RESULTS Individuals with BED meaningfully differ from individuals without eating disorders, and share important similarities to, yet are distinct from, individuals with anorexia nervosa (AN) and bulimia nervosa (BN). BED is associated with co-occurring physical and mental illnesses, as well as impaired quality of life and social functioning. Questions about the course of the disorder and the optimal treatment regimen for the syndrome need to be explored further. DISCUSSION BED's distinctive combination of core eating disorder psychopathology, and other co-occurring physical and psychiatric conditions, impaired psychosocial functioning, and overweight constitute an eating disorder of clinical severity and a significant public health problem.

Abstract
This study compared patients with bulimia nervosa (BN), obese patients with binge eating disorder (BED), and nonobese patients with BED. One hundred sixty-two adult women consecutively evaluated for outpatient clinical trials who met DSM-IV criteria for BN, purging type (N = 46) or for BED (N = 79 obese and N = 37 nonobese) were compared using the Eating Disorder Inventory (EDI). The three groups differed significantly on two (drive for thinness and body dissatisfaction) of the three eating-related scales and on all five of the general personality scales of the EDI. When age and depression level were controlled, findings for the eating-related scales did not change, whereas four of the five general personality scales were no longer significant. Post hoc analyses revealed that the BN group and the nonobese BED group had significantly higher drive for thinness than the obese BED group. The nonobese and the obese BED groups did not differ from each other in any area (other than drive for thinness), including body dissatisfaction. The nonobese and the obese BED groups had significantly lower maturity features than the BN group. Our findings suggest that when the effects of age and depression levels are controlled, treatment-seeking women with BN and BED are generally similar. Certain differences that do exist between women with BN and BED are associated with obesity status (drive for thinness), whereas others are associated with diagnosis (body dissatisfaction, maturity fears).

Abstract
OBJECTIVE To examine binge eating and eating-related cognitions and behavior in a sample of ethnically diverse women who are severely obese and seeking bariatric surgery. RESEARCH METHODS AND PROCEDURES Female bariatric surgery candidates (62 African Americans, 18 Latinas, 130 whites) completed questionnaires on binge eating and eating-related cognitions and behavior and completed a structured clinical interview to confirm binge-eating disorder diagnosis. RESULTS Ethnic minorities and whites did not differ in rates of binge-eating disorder (26.3%), binges per week (M = 0.95), or dietary restraint. Ethnic minorities reported less disinhibition, and there was a trend to report less hunger awareness than whites. After controlling for BMI and education, ethnicity accounted for significant variance in disinhibition (4%; p < 0.01). Ethnic minorities were younger, became overweight at a later age, and were overweight for fewer years than whites. DISCUSSION Results suggest that ethnicity exerts an important influence on disinhibition and that ethnic differences are not caused by BMI or education. Findings point to the need to continue to investigate the role of ethnicity, binge eating, and disinhibition in severely obese women, so that culturally appropriate services can be provided.

Abstract
The prevalence of depression (10%) and overweight (65%) indicates that there is a probability that they will co-occur, but are they functionally related? This report used the moderator/mediator distinction to approach this question. Moderators, such as severity of depression, severity of obesity, gender, socioeconomic status (SES), gene-by-environment interactions and childhood experiences, specify for whom and under what conditions effects of agents occur. Mediators, such as eating and physical activity, teasing, disordered eating and stress, identify why and how they exert these effects. Major depression among adolescents predicted a greater body mass index (BMI = kg/m(2)) in adult life than for persons who had not been depressed. Among women, obesity is related to major depression, and this relationship increases among those of high SES, while among men, there is an inverse relationship between depression and obesity, and there is no relationship with SES. A genetic susceptibility to both depression and obesity may be expressed by environmental influences. Adverse childhood experiences promote the development of both depression and obesity, and, presumably, their co-occurrence. As most knowledge about the relationship between these two factors results from research devoted to other topics, a systematic exploration of this relationship would help to elucidate causal mechanisms and opportunities for prevention and treatment.

Abstract
BACKGROUND Experimental findings causally link restrictive child-feeding practices to overeating in children. However, longitudinal data are needed to determine the extent to which restrictive feeding practices promote overeating. OBJECTIVES Our objectives were to determine whether restrictive feeding practices foster girls' eating in the absence of hunger (EAH) and whether girls' weight status moderates the effects of restrictive feeding practices. DESIGN Longitudinal data were used to create a study design featuring 2 maternal restriction factors (low and high), 2 weight-status factors (nonoverweight and overweight), and 3 time factors (ages 5, 7, and 9 y). RESULTS Mean EAH increased significantly (P < 0.0001) from 5 to 9 y of age. Higher levels of restriction at 5 y of age predicted higher EAH at 7 y of age (P < 0.001) and at 9 y of age (P < 0.01). Girls who were already overweight at 5 y of age and who received higher levels of restriction had the highest EAH scores at 9 y of age (P < 0.05) and the greatest increases in EAH from 5 to 9 y of age (P < 0.01). CONCLUSIONS The developmental increase in EAH from 5 to 9 y of age may be especially problematic in obesigenic environments. These longitudinal data provide evidence that maternal restriction can promote overeating. Girls who are already overweight at 5 y of age may be genetically predisposed to be especially responsive to environmental cues. These findings are not expected to be generalized to boys or to other racial and ethnic groups.
