In this study we describe the frequency of eating disorders (EDs) in a group of bipolar (BP) patients. We evaluated a sample of 51 outpatients, diagnosed as having BP I disorder on the basis of the Structured Clinical Interview for DSM-IV (SCID). Each of these subjects was administered the Binge Eating Disorder Clinical Interview (BEDCI) to determine the presence of binge eating disorder (BED) or bulimia nervosa (BN). Of the 51 BP patients, 14 (9 BED, 5 BN) met criteria for an ED. Most patients developed binge eating coincident with the first episode of BP disorder or after the onset of it. This was true for those who developed BED as well as BN, and involved both manic and depressive phases. All BN patients were women (5/5), and family history of binge eating was present in 80% of BN subjects, but only in 22.2% of BED and 29.7% of non-ED BP patients. We found a high frequency of concordance between BP illness and binge eating problems in our sample of BP patients. Given the temporal sequence of the mood disorder, which generally preceded the ED, we suggest a model in which the ED evolves due to modulation of emotions with food, as well as use of medications to treat BP disorder that disrupt hunger and satiety mechanisms. Given differences in gender distribution and family history, cultural and familial influences may also be significant in the minority of BP binge-eating patients who develop BN. 相似文献

The purpose of this study was to test the impact of two variables on post-binge eating negative emotion in a combined sample of women with anorexia nervosa (AN; n = 47) and bulimia nervosa (BN; n = 121). Participants completed two weeks of an ecological momentary assessment protocol during which they provided multiple daily ratings of overall negative affect and guilt and reported eating disorder behaviors including binge eating and self-induced vomiting. The results indicate that both overall negative affect and guilt exhibited a statistically significantly decrease in the hour immediately following binge eating episodes. The decrease in guilt, but not overall negative affect, was moderated by eating disorder diagnosis and the tendency to engage in self-induced vomiting. Specifically, individuals with BN reported a greater reduction in guilt than those with AN, and individuals who did not typically engage in self-induced vomiting reported more decreases in guilt than those who typically engaged in self-induced vomiting. This study extends the existing literature on the relationship between negative affect and eating disorder behaviors, suggesting guilt as a potentially relevant facet of negative affect in the maintenance of binge eating. In addition, the findings indicate that two individual differences, eating disorder diagnosis and self-induced vomiting, may influence the trajectory of guilt following binge eating episodes. 相似文献

OBJECTIVE: Male bodybuilders (MBB) exhibit more severe body dissatisfaction, bulimic eating behaviour, and negative psychological characteristics, compared with male athletic and nonathletic control subjects, but few studies have directly compared MBB and men with eating disorders. This study compared men with bulimia nervosa (MBN), competitive male bodybuilders (CMBB), and recreational male bodybuilders (RMBB) on a broad range of eating attitudes and behaviours and psychological characteristics to more accurately determine similarities and differences among these groups. METHOD: Anonymous questionnaires, designed to assess eating attitudes, body image, weight and shape preoccupation, prevalence of binge eating, weight loss practices, lifetime rates of eating disorders, anabolic androgenic steroid (AAS) use, and general psychological factors, were completed by 22 MBN, 27 CMBB, and 25 RMBB. RESULTS: High rates of weight and shape preoccupation, extreme body modification practices, binge eating, and bulimia nervosa (BN) were reported among MBB, especially among those who competed. CMBB reported higher rates of binge eating, BN, and AAS use compared with RMBB, but exhibited less eating-related and general psychopathology compared with MBN. Few psychological differences were found between CMBB and RMBB. CONCLUSIONS: MBB, especially competitors, and MBN appear to share many eating-related features but few general psychological ones. Longitudinal research is needed to determine whether men with a history of disordered eating or BN disproportionately gravitate to competitive bodybuildin and (or) whether competitive bodybuilding fosters disordered eating, BN, and AAS use. 相似文献

OBJECTIVE: This study aimed to estimate the lifetime frequency of suicide attempts in a large referred population of women with DSM-IV bulimia nervosa (BN), and to compare demographic and clinical characteristics of those who had attempted suicide and those who had not. METHOD: A total of 295 women (202 with BN purging type, 68 with BN non-purging type and 25 with anorexia nervosa binge/eating purging type) were assessed using a semi-structured interview and self-rated questionnaires. RESULTS: Suicide attempts were frequent (27.8% of women), often serious and/or multiple. Women who had attempted suicide differed significantly from those who had not for earlier onset of psychopathology, higher severity of depressive and general symptoms, and more impulsive disordered conducts, but not for the core symptoms or severity of BN. CONCLUSION: Interventions targeting depressive and impulsive features associated with BN are essential to reduce the risk of suicide attempt in women with this disorder. 相似文献

The affect regulation model of binge eating suggests that binge eating occurs because it provides momentary relief from negative affect. The purpose of this study was to evaluate change in affect during binge eating to evaluate the merits of this model. Participants were young adult women from a midwestern university. Binge eaters recorded their level of pleasantness using the affect grid at 2-minute intervals before, during, and after binge eating episodes and regular meals. Controls recorded in a similar manner during meals. The results showed a different pattern of affect for binge eaters during binge eating episodes and normal meals and for binge eaters and controls at normal meals. The results support the affect regulation model of binge eating and suggest that binge eating is negatively reinforced because it produces momentary relief from negative affect. 相似文献

Inhibition of gastric emptying leads to enhanced satiety and this mechanism may contribute to the undereating observed after administration of cholecystokinin (CCK) and fenfluramine, and in patients with anorexia nervosa. Pyloric smooth muscle bears specific CCK receptors and the evidence suggests that a major site of action for CCK satiety is in the periphery. CCK receptors are widespread in the neonatal rat stomach but not in the brain and over the first two weeks of life binding in the stomach decreases and that in the brain increases. This and the finding that independent ingestion as well as gastric emptying are inhibited by CCK at birth suggest the stomach as its likely site of action in the neonatal rat. Fenfluramine inhibits feeding in animals and in patients with bulimia nervosa. In monkeys, fenfluramine inhibits gastric emptying and this action correlates with its feeding inhibition. Patients with anorexia nervosa who are acutely starving and rats maintained on a restricted diet have delayed gastric emptying. Anorexic patients showed abnormal reporting of both hunger and satiety, and, together with those with bulimia nervosa, often associated gastric contents with symptoms of eating disorder, indicating disturbed interpretation of gastric signals. 相似文献

To examine how different definitions of recovery lead to varying rates of recovery, maintenance of recovery, and relapse in bulimia nervosa (BN), end-of-treatment (EOT) and follow-up data were obtained from 96 adults with BN. Combining behavioral, physical, and psychological criteria led to recovery rates between 15.5% and 34.4% at EOT, though relapse was approximately 50%. Combining these criteria and requiring abstinence from binge eating and purging when defining recovery may lead to lower recovery rates than those found in previous studies; however, a strength of this definition is that individuals who meet this criteria have no remaining disordered behaviors or symptoms. 相似文献

PurposeBinge eating disorder (BED), bulimia nervosa (BN) and recurrent binge eating (RBE) are binge eating spectrum conditions causing a significant impact in individual’s health and functioning. Information regarding those conditions came mostly from high-income countries. The objective of this study was to assess the prevalence of DSM-5 BED, BN and RBE and correlates in a representative sample from a metropolitan area of a middle-income country. MethodsThe data were obtained from a cross-sectional population-based household survey in two stages in Rio de Janeiro, Brazil. Noninstitutionalized residents aged 18–60 years were assessed by lay interviewers using the Questionnaire of Eating and Weight Patterns-5 (QEWP-5). Positive cases and a paired sample screen-negative cases were reassessed by phone with the Eating Disorders Section of SCID-I-P (adapted for DSM-5). The data were collected from September 2019 to February 2020. ResultsOverall, 2297 individuals were interviewed. Prevalence of BED was 1.4%, BN 0.7%, RBE 6.2%. Psychiatric comorbidities, such as depression, anxiety and ADHD were significantly more prevalent in people with BED, BN and RBE than in people without these eating problems. Several medical conditions, when controlling for body mass index, were significantly more prevalent in people with BED, BN and RBE. People with BED and BN had marked impairments in work/school, social and family life, reduced mental and physical HRQoL and under half had sought treatment. ConclusionAs in high income countries, in Rio de Janeiro, Brazil, BED, BN and RBE are prevalent conditions and are associated with elevated BMI, functional impairment, psychiatric and medical comorbidity and poorer HRQoL. 相似文献

Current explanatory models for binge eating in binge eating disorder (BED) mostly rely on models for bulimia nervosa (BN), although research indicates different antecedents for binge eating in BED. This study investigates antecedents and maintaining factors in terms of positive mood, negative mood and tension in a sample of 22 women with BED using ecological momentary assessment over a 1-week. Values for negative mood were higher and those for positive mood lower during binge days compared with non-binge days. During binge days, negative mood and tension both strongly and significantly increased and positive mood strongly and significantly decreased at the first binge episode, followed by a slight though significant, and longer lasting decrease (negative mood, tension) or increase (positive mood) during a 4-h observation period following binge eating. Binge eating in BED seems to be triggered by an immediate breakdown of emotion regulation. There are no indications of an accumulation of negative mood triggering binge eating followed by immediate reinforcing mechanisms in terms of substantial and stable improvement of mood as observed in BN. These differences implicate a further specification of etiological models and could serve as a basis for developing new treatment approaches for BED. 相似文献

OBJECTIVE: To describe an "integrated inpatient therapy" for type 1 diabetic patients with recurrent binge eating and to assess its effectiveness for females with bulimia nervosa (BN). METHODS: At the first visit to our outpatient clinic for treatment of an eating disorder and diabetes, type 1 diabetic females with BN underwent single session "outpatient counseling." All patients then returned to the referring physician for further treatment and observation. None of the BN patients had the minimum expected 1% fall in HbA1c and all were therefore encouraged to undergo our "integrated inpatient therapy." However, only patients accepting inpatient treatment on their own volition were admitted. An "INPATIENT" group (n=9) consisted of those who underwent inpatient therapy and had a 3-year follow-up period after discharge. The clinical course was assessed by the HbA1c and BMI course and by comparison of psychological/behavioral factors between baseline and follow-up. For reference, the clinical course of a "NON-INPATIENT" group (n=10), who did not have the inpatient therapy for at least 2 years after first visit, was also assessed. RESULTS: The "INPATIENTs" had significantly lower HbA1c; lower psychological test scores related to eating disorder psychopathology, depressiveness, and anxiety-proneness; a reduced frequency and amount of binge eating; and fewer patients exhibited purging behaviors at follow-up than at first visit. At follow-up, seven (78%) "INPATIENTs" no longer fulfilled any criterion for clinical or subclinical eating disorders. The "NON-INPATIENTs" had no significant improvement. CONCLUSION: The findings give interesting insights into the possibilities of "integrated inpatient therapy" as an effective treatment for type 1 diabetic females with BN. 相似文献

This study explored the differences between bulimia nervosa ("BN," n=22) and binge-eating disorder ("BED," n=11) in type 1 diabetic females and the factors most predictive of poor glycemic control in patients suffering from these disorders. These two groups and a control group without eating disorders (n=32) were compared across a number of demographic, psychological, and medical variables. BN manifested significantly more severe disturbances related to eating disorders, depression, anxiety, a higher rate of co-occurring mental disorders, and poorer psychosocial functioning compared with BED. BN also showed poorer glycemic control. Multivariate analysis indicated that higher serum glycosylated hemoglobin (HbA1c) levels were most associated with the presence of severe insulin omission in type 1 diabetic females with binge eating. Clinicians may be able to determine the psychological/medical severity of illness in these patients by identifying the presence of compensatory behaviors to prevent weight gain such as severe insulin omission, as described in the DSM-IV. 相似文献

OBJECTIVE: Binge eating disorder was introduced in DSM-IV as a psychiatric disorder needing further study. This community-based study describes the relationship between race and clinical functioning in black and white women with and without binge eating disorder. METHOD: A group of 150 women with binge eating disorder (52 black, 98 white) and a race-matched group of 150 healthy comparison subjects were recruited from the community. Eating and psychiatric symptoms were assessed through interviews and self-report. RESULTS: Black and white women with binge eating disorder differed significantly on numerous eating disorder features, including binge frequency, restraint, history of other eating disorders, treatment-seeking behavior, and concerns with eating, weight, and shape. Black and white healthy comparison subjects differed significantly in obesity rates. CONCLUSIONS: For both black and white women, binge eating disorder was associated with significant impairment in clinical functioning. Yet, racial differences in clinical presentation underscore the importance of considering race in psychopathology research. 相似文献

ABSTRACTNegative urgency (NU), the tendency to act impulsively when distressed, is associated with binge eating. Women who believe that eating alleviates negative affect are also more likely to binge eat. Thus, it is hypothesized that the individuals with high levels of NU, and who endorse these eating expectancies, will binge eat the following acute distress. This study tested these hypotheses using ecological momentary assessment. Sixteen women with the symptoms of BN completed clinical assessments, and were asked to report on distress and binges multiple times daily for two weeks. NU moderated the temporal relationship of negative affect to binges, such that women with lower scores on NU experienced a sharper increase in affect prior to binges. Individual differences in eating expectancies also moderated the relationship of affect to binge eating. Results suggest that women with high levels of NU and expectancy endorsement are triggered to binge by smaller shifts in negative affect than women who do not endorse these traits. 相似文献

Preti A, Rocchi MBL, Sisti D, Camboni MV, Miotto P. A comprehensive meta‐analysis of the risk of suicide in eating disorders. Objective: Past meta‐analyses on suicide in eating disorders included few available studies. Method: PubMed/Medline search for papers including sample n ≥ 40 and follow‐up ≥5 years: 40 studies on anorexia nervosa (AN), 16 studies on bulimia nervosa (BN), and three studies on binge eating disorder (BED) were included. Results: Of 16 342 patients with AN, 245 suicides occurred over a mean follow‐up of 11.1 years (suicide rate = 0.124 per 100 person‐years). Standardized mortality ratio (SMR) was 31.0 (Poisson 95% CI = 21.0–44.0); a clear decrease in suicide risk over time was observed in recent decades. Of 1768 patients with BN, four suicides occurred over a mean follow‐up of 7.5 years (suicide rate = 0.030 per 100 person‐years): SMR was 7.5 (1.6–11.6). No suicide occurred among 246 patients with BED (mean follow‐up = 5.3 years). Conclusion: AN and BN share many risk factors for suicide: the factors causing lower suicide rates per person‐year in BN compared to AN should be investigated. 相似文献

ObjectivesThe relationship between emotional states and eating behaviors is complex, and emotional eating has been identified as a possible factor triggering binge eating in bulimia nervosa (BN) and binge eating disorder. Few studies considered emotional eating in patients with anorexia nervosa. MethodsThe present study evaluated the clinical correlates of emotional eating in 251 eating-disordered (EDs) subjects (70 AN restricting type, 71 AN binge eating/purging type, 110 BN purging type) and in a group of 89 healthy control subjects. Subjects were assessed by means of a clinical interview (Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) and several self-reported questionnaires, including the Emotional Eating Scale (EES). ResultsNo significant differences were found between the 3 EDs groups in terms of EES total score, and all patients with ED showed higher EES scores compared with control subjects. Emotional eating was associated with subjective binge eating in AN binge eating/purging type and with objective binge eating in patients with BN. Among patients with AN restricting type, emotional eating was associated with restraint, but this association was lost when controlling for fear of loss of control over eating, which was the principal determinant of restraint. ConclusionEmotional eating and fear of loss of control over eating are significantly associated with specific eating attitudes and behaviors, according to the different diagnoses. Emotional eating is a relevant psychopathologic dimension that deserves a careful investigation in both anorectic and bulimic patients. 相似文献

This study compares the core and associated features of binge eating disorder (BED) and bulimia nervosa (BN). One hundred twenty-nine adult females who were obese with BED (n = 51) or non-obese with BED (n = 32) or who had BN (n = 46) were compared using the Eating Disorder Examination-Questionnaire (EDE-Q). The BED groups were older and had a higher body mass index (BMI). The 3 groups were similar in binge frequency, but BN subjects (by definition) purged regularly. The groups differed by dietary restraint, even after controlling for BMI and age, such that the BN group had significantly higher dietary restraint than both BED groups. Cognitively, the 3 groups were similar in the intensity of dysfunctional attitudes regarding eating, weight, and shape. The BMI and age were not associated with these dysfunctional attitudes. Our findings suggest the importance of and the need to consider cognitive--as well as behavioral--diagnostic criteria for BED. 相似文献

BACKGROUND: Individuals who are ill with anorexia (AN) and bulimia nervosa (BN) often have increased cerebrospinal fluid (CSF) volumes and decreased total gray and white matter volumes. It is unclear whether such disturbances persist after recovery from an eating disorder. METHODS: Magnetic resonance imaging was performed on 40 women who were long-term recovered (>1 year no binging, purging, or restricting behaviors, normal weight, and menstrual cycles, not on medication) from restricting or binge/purging type AN or BN and 31 healthy control women (CW). Voxel-based morphometry (VBM) was used for data analysis. RESULTS: Recovered AN and BN subgroups were similar to CW in terms of cerebrospinal fluid (CSF) volume as well as total or regional gray or white matter volume. CONCLUSIONS: These findings suggest that structural brain abnormalities are reversible in individuals with eating disorders after long-term recovery. 相似文献

OBJECTIVE: Few studies exist that have examined the spectrum and natural long-term course of eating disturbance in the community. We examine the lifetime prevalence and long-term course of anorexia nervosa (AN), bulimia nervosa (BN) and eating disorder not otherwise specified (EDNOS) in an adult female twin population. METHOD: Female twins (n = 1002) from the Australian Twin Registry, aged 28-39 years, were assessed using the Eating Disorder Examination, revised to yield lifetime diagnostic information. For women with lifetime eating disorders, the assessment occurred, on average, 14.52 years (SD = 5.65) after onset of their disorder. RESULTS: In accordance with other community studies, we found a 1.9% lifetime prevalence of AN, with an additional 2.4% who met the criteria for 'partial AN' (absence of amenorrhea). Criteria for BN were met by 2.9% of the women, an additional 2.9% of women met criteria for binge eating disorder, while 5.3% met criteria for purging disorder unaccompanied by binge eating (EDNOS-p). Eleven (7%) of the women with lifetime eating disorders had a current eating disorder. Each diagnostic group continued to be differentiated by current eating pathology from women without lifetime eating disorders. Although approximately 75% of the women had a good outcome, less than 50% of each diagnostic group was asymptomatic. CONCLUSIONS: Eating disorders tend to improve over time often reaching subdiagnostic levels of severity, but only a minority of sufferers becomes asymptomatic. The DSM-IV diagnosis EDNOS needs to be considered in studies of the prevalence and course of eating disorders. 相似文献

Individuals with Prader-Willi syndrome (PWS) are often overweight or obese because of their delayed satiety response. Three individuals with PWS participated in a long-term, multicomponent mindfulness-based health wellness program to reduce their obesity by changing their lifestyles. The components included (a) physical exercise, (b) food awareness, (c) mindful eating to manage rapid eating, (d) visualizing and labeling hunger, and (e) a mindfulness procedure used as a self-control strategy against temptation to eat between meals. The program was implemented within a changing criterion design. All 3 individuals reached their desired body weights, enhanced their lifestyles, and maintained their desired body weights during the 3-year maintenance period. This study suggests that mindfulness-based health wellness programs may be effective in producing sustained lifestyle changes in individuals who are obese, including those with a biological predilection for excessive eating due to delayed satiety response. 相似文献

To obtain objective information about binge- and non-binge-eating behavior, 12 women with bulimia and ten women without eating problems (controls) were asked to eat four meals in a structured laboratory setting, on separate nonconsecutive days. The same instructions were given to both groups. On two days, they were asked to eat a normal amount, and on two days, they were asked to eat as much as they could, ie, to binge. For each type of instruction, they were given a single- and a multiple-course meal. The patients ate significantly more than the controls when asked to binge, both on the multiple-course meals that they rated as typical of binges and on the single-course meals. When they were asked to eat normally, there was no significant difference in intake between patients and controls on either single- or multiple-course meals. After all meals, hunger ratings of patients were significantly higher than hunger ratings of controls. There was also a significant positive correlation between intakes of single- and multiple-course binge meals and an inverse correlation between intake of multiple-course binge meals in bulimic patients and their rating of how well they controlled their eating. Thus, a structured laboratory eating situation can be used to reveal differences between bulimic and normal individuals and has the potential for assessing clinical status and exploring mechanisms responsible for binge eating. 相似文献
