Few data are available to estimate the prevalence of eating disorders (EDs) and their correlates in the community. This paper reports data on EDs obtained in the framework of the ESEMeD project, aimed at investigating the prevalence of non-psychotic mental disorders in six European countries (Belgium, France, Germany, Italy, the Netherlands and Spain), using a new version of the Composite International Diagnostic Interview. The ESEMeD study was a general population cross-sectional household survey. In total, 21,425 respondents aged 18 or older provided data for the project between January 2001 and August 2003. A subsample ( N = 4139) underwent a detailed investigation on EDs. Lifetime estimated prevalence of anorexia nervosa, bulimia nervosa, binge eating disorder, sub-threshold binge eating disorder, and any binge eating were 0.48%, 0.51%, 1.12%, 0.72%, and 2.15%, respectively, and they were 3-8 times higher among women for all EDs. However, since people under 18 were excluded from this study, our prevalence should be taken as lower-bound estimate of real frequencies. Indeed, cumulative lifetime prevalence analysis showed that the majority of eating disorders had their initial onset between 10 and 20 years of age. Role impairment and comorbidity with other mental disorders were highly common, yet only small proportions of patients with a lifetime diagnosis of EDs requested medical treatment. It still has to be proven whether early diagnostic identification and access to specialized care can reduce the burden caused by these disorders. 相似文献

BackgroundFood Craving (FC) is a construct influenced by cognitive, emotional, physiological and external components, severely altered in Eating Disorders (EDs). ObjectivesTo investigate how FC was measured in EDs. MethodsA search was conducted (PubMed, Scopus and PsycINFO databases) for studies that have investigated FC in EDs published in the last thirty years. ResultsThe studies found ( n= 37) demonstrated that FC is a predictor of binge eating in individuals with Bulimia Nervosa and Binge Eating Disorder, which are more sensitive to the environment and emotional factors, whereas, in individuals with Anorexia Nervosa, FC levels are lower. DiscussionFC is a physiological component of eating behavior, as well as the craving/urge that arises associated with thirst during dehydration, and food restriction is a crucial mechanism for the restriction-binge cycle to hold. Further studies are needed to see if FC increases in response to treatment for Anorexia Nervosa, recognizing that individuals without Anorexia Nervosa have higher FC levels and greater motivational orientation towards food. ConclusionsIt is necessary to understand the physiological role of FC and also consider the significance of each food in an individual eating context (eating attitudes) and whether it is treated like a “drug” or just as a desired tasty food and future studies should verify possible neural changes involved in FC after nutritional treatment. 相似文献

ObjectiveHealth-related quality of life (HRQoL) is an emerging area of research in eating disorders (EDs) that has not been examined in adolescents in detail. The aim of the current study is to investigate HRQoL in an adolescent ED sample, examining the impact of ED symptoms on HRQoL. MethodsSixty-seven treatment-seeking adolescents (57 females) with anorexia nervosa (AN), bulimia nervosa (BN), or eating disorder not otherwise specified (EDNOS) completed self-report measures of HRQoL and ED symptoms. ResultsParticipants reported poorer HRQoL in mental health domains than in physical health domains. Disordered attitudes, binge eating, and compensatory behaviors were associated with poorer mental health HRQoL, and body dissatisfaction was associated with poorer physical health HRQoL. ConclusionThe current study assessed HRQoL among adolescents with EDs, finding several consistencies with the literature on adults with EDs. Future research should compare adolescents and adults with EDs on HRQoL. 相似文献

The growing interest in the treatment and research of eating disorders has stimulated the development of assessment methods, and there are now many questionnaires for evaluating behavioral and attitudinal characteristics of eating pathology. The present article sets out to review the assessment tools that are widely used in clinical practice and research. In particular, it covers self-report measures with summaries of their psychometric properties. It also presents diagnostic questionnaires based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnostic criteria. The instruments described include screening questionnaires, measurement tools for specific eating disorder symptoms, measurement of quality of life in eating disorders, and some tools for the measurement of body image disorder, a common feature of eating disorders. There is also a discussion of distorting factors that decrease the authenticity of assessment tools. These problems arise from the definition of some constructs and from the phenomena of denial and concealment, which are frequent among eating-disordered individuals. The frequent co-occurrence of other psychopathological features (e.g., multiimpulsive symptoms) shows that other psychological phenomena should also be evaluated in line with the assessment of eating disorders. 相似文献

BackgroundFunctional gastrointestinal-like disorders (FGIDs) are prevalent among eating disorder (ED) patients. The aims are to explore the relationship between quality of life related to eating disorders (QOL ED) and FGIDs. MethodsConsecutive ED patients, 18-45 years old, completed the Rome II, QOL ED, Irritable Bowel Syndrome QOL (IBS-QOL) and Bowel Symptom Severity Index (BSSI) questionnaires on admission to hospital for treatment of their ED. ResultsDespite the high prevalence of FGIDs (93%), only IBS is clearly correlated with QOL ED scores. The QOL ED subscores significantly related are ED feelings, psychological feelings and effect on daily living. These subscores contain items such as fearing loss of control over your body and feelings, being preoccupied with thoughts of body weight and shape, feeling confused and that eating and exercise have a negative effect on work/study. There were no relationships between QOL ED behavior and individual FGIDs or categories of FGIDs. The QOL ED and IBS-QOL are highly correlated, and there is a positive linear relationship between the QOL ED global and IBS-QOL total and BSSI scores. ConclusionThe presence of IBS (but not other FGIDs) in ED patients is strongly related to eating disordered and psychological feelings. The poorer the QOL ED is, the poorer the IBS-QOL is and the more severe the IBS symptoms are. 相似文献

Background: Adults with eating disorders (ED) show brain volume reductions in the frontal, insular, cingulate, and parietal cortices, as well as differences in subcortical regions associated with reward processing. However, little is known about the structural differences in adolescents with behavioural indications of early stage ED. Aim: This is the first study to investigate structural brain changes in adolescents newly diagnosed with ED compared to healthy controls (HC), and to study whether ED cognitions correlate with structural changes in adolescents with ED of short duration. Methods: Fifteen adolescent females recently diagnosed with ED, and 28 age-matched HC individuals, were scanned with structural magnetic resonance imaging (MRI). Whole-brain and region-of-interest analyses were conducted using voxel-based morphometry (VBM). ED cognitions were measured with self-report questionnaires and working memory performance was measured with a neuropsychological computerized test. Results and conclusions: The left superior temporal gyrus had a smaller volume in adolescents with ED than in HC, which correlated with ED cognitions (concerns about eating, weight, and shape). Working memory reaction time correlated positively with insula volumes in ED participants, but not HC. In ED, measurements of restraint and obsession was negatively correlated with temporal gyrus volumes, and positively correlated with cerebellar and striatal volumes. Thus, adolescents with a recent diagnosis of ED had volumetric variations in brain areas linked to ED cognitions, obsessions, and working memory. The findings emphasize the importance of early identification of illness, before potential long-term effects on structure and behaviour occur. 相似文献

Summary The somatosensor functions of small-diameter nerve fibres were tested on the lower and upper extremities in nine patients with anorexia nervosa, ten patients with bulimia nervosa and ten control subjects, by analysing warmth, cold, and pain thresholds. To test large-diaeter nerve fibres, the vibration threshold was also measured, Both patient groups had markedly elevated pain thresholds compared with the control subjects. In contrast, warmth and cold thresholds were only suggestively elevated while vibration thresholds were not at all increased in the patients. A distal-proximal pattern of somatosensory deficients, suggestive of peripheral polyneuropathy, was not observed. Hence, a peripheral polyneuropathy affecting small or large afferent fibres as a consequence of an eating disorder seems to be a rare event. 相似文献

ObjectiveThe aim of the present study is to see if the changes in the regional cerebral blood flow (rCBF) experienced by restrictive anorexia nervosa (AR) and bulimia nervosa (BN) patients, following the exposure to their own body image, persist at follow-up. MethodsThree single photon emission computed tomography (SPECT) were performed on nine patients with a DSM-IV diagnosis of AR, 13 with BP, and 12 controls: at rest, following a neutral stimulus, and after exposure to their previously filmed whole body image. Body dissatisfaction was measured by means of the Body Dissatisfaction Questionnaire (BSQ). One year later the same assessment was repeated. ResultsFollowing the exposure to their own body image, BN showed an increase in body dissatisfaction, which was associated with the increase in the rCBF of the Right Temporal Area. Those changes persisted at follow-up. DiscussionMore specific long term therapies are needed for the treatment of the averse response showed by ED patients to their own body image exposure that is associated with the hyperactivation of the right temporal area when they are confronted with their whole body image. 相似文献

Objectives: This study attempts to understand the clinical impact of marital status on the psychopathology and symptomatology of anorexia (AN) and bulimia nervosa (BN) patients. Method: Eating disorder (ED) patients ( n=332, 198 BN and 134 AN) consecutively admitted to our unit participated in the study. All subjects met DSM-IV criteria for those pathologies and were female. Our sample was divided retrospectively into three subgroups based on their marital status. For the assessment, commonly applied questionnaires in the field of ED were used [Eating Attitudes Test (EAT-40), Eating Disorder Inventory (EDI), Bulimic Investigatory Test Edinburgh (BITE), Body Shape Questionnaire (BSQ), Beck Depression Inventory (BDI) and Social Avoidance and Distress Scale (SAD)]. Results: 2×3 (Diagnostic×Marital status) ANOVA and ANCOVA (with age as covariance) designs were applied in the current study. Our results suggested that ED patients who lived with a partner were significantly different with respect to the other ED patients in the following variables: higher age ( P<.0001), higher motivation for change ( P<.004), perfectionism ( P<.03) and purging behavior ( P<.04). Discussion: The main finding in this study is that ED patients who live with a partner are those who presented greater eating symptomatology and psychopathology but even higher motivation for change. Interpersonal functionality has to be considered in the development and maintenance of ED. 相似文献

Elevated plasma homocysteine levels have been found in different psychiatric disorders, including major depression and eating disorders. The aim of the present study was to evaluate whether presence of depression or depressive symptoms is associated with elevated homocysteine levels in patients with eating disorders. Total plasma homocysteine levels were assessed in 44 females with anorexia nervosa (n = 21) or bulimia nervosa (n = 23). Comorbid major depressive disorder (MDD) was diagnosed according to DSM-IV criteria using a semi-structured interview (SCID-I). Furthermore, depressive symptoms were assessed using Beck's depression inventory (BDI). Presence of MDD was not associated with elevated homocysteine levels (t-test: T = 0.42; df = 42; P = 0.68). However, self-rated presence of clinically relevant depressive symptoms (BDI score18) was associated with elevated homocysteine (T = -2.8; df = 42; P = 0.008). Presence of depressive symptoms may explain elevated homocysteine levels previously reported in patients with eating disorders or vice versa. Longitudinal studies are needed to unravel this hen or egg problem. 相似文献

People with eating disorders (ED) have difficulties regulating their emotions adaptively. Little is known about differences and similarities between different types of ED and how these regulation difficulties relate to other emotional problems. The present study examines maladaptive (suppression) and adaptive (cognitive reappraisal) emotion regulation strategies in women with different ED and relationships with anxiety and depression levels. In 32 women with AN restrictive subtype (ANR), 32 with AN binge-purge subtype (ANBP), 30 with bulimia nervosa (BN), 29 with binge eating disorder (BED), and 64 healthy women, the ERQ (emotion regulation) as well as STAI-T (anxiety), BDI-SF (depression), and EDDS (eating pathology) were administered. Women across different ED subtypes were inclined to suppress emotions and lacked the capacity to reappraise emotions (except women with ANBP). Correlational relations of suppression and reappraisal with anxiety and depression levels differed across ED groups. Emotion regulation problems were found across ED subtypes. However, the types of emotion regulation problems, and the effect of coexisting other emotional problems such as anxiety and depression may differ across ED subtypes. These findings illustrate the importance to of considering ED subtypes in emotion regulation research rather than consider ED as a whole. 相似文献

ObjectiveSocial perception is a key aspect of social cognition which has so far not been investigated in eating disorders (ED). This study aimed to investigate social perception in individuals with anorexia nervosa (AN) and bulimia nervosa (BN). MethodsOutpatients with AN (restricting subtype [AN-R]: n = 51; binge-purge subtype [AN-BP]: n = 26) or BN ( n = 57) and 50 healthy control (HC) participants completed the Interpersonal Perception Task (IPT-15). This is an ecologically valid task, which consists of 15 video clips, depicting complex social situations relating to intimacy, status, kinship, competition and deception . The participants have to assess relationships between protagonists’ based on non-verbal cues. ResultsOverall, there was no difference between groups on the IPT total score and subscale scores. Group differences on the Intimacy subscale approached significance so post hoc comparisons were carried out. HCs performed significantly better than AN-R participants in determining the degree of intimacy between others. ConclusionsSocial perception is largely preserved in ED patients. Individuals with AN-R show impairments in identifying intimacy in social situations, this may be due to the lack of relationship experience. Further research into different aspects of social cognition is required to establish the link between interpersonal difficulties and ED psychopathology. 相似文献

OBJECTIVE: The prevalence of eating disorders (EDs) in a representative scholastic sample was evaluated, and the demographic factors associated with ED were assessed. METHOD: The study used a two-stage epidemiological design. The study population was a randomly selected sample of 1545 students (12- to 21-year-old males and females) in the region of Madrid (Spain). RESULTS: ED prevalence was 3.43%. Prevalence estimations were as follows: 5.34% for females: 2.72% for eating disorders not otherwise specified (EDNOS), 2.29% for bulimia nervosa (BN), and 0.33% for anorexia nervosa (AN); and 0.64% for males: 0.48% for EDNOS, 0.16% for BN, and 0.00% for AN. Some demographic factors that were shown to be associated with ED included the following: sex, age, single child, single-parent families, and father or mother's death. DISCUSSION: Despite the methodological improvements over previous epidemiological studies developed in Spain, there were no significant differences in the prevalence estimations. 相似文献

ObjectiveResearch investigating the link between eating disorder (ED) diagnosis and executive dysfunction has had conflicting results, yet no meta-analyses have examined the overall association of ED pathology with executive functioning (EF). MethodEffect sizes were extracted from 32 studies comparing ED groups (27 of anorexia nervosa, 9 of bulimia nervosa) with controls to determine the grand mean effect on EF. Analyses included effects for individual EF measures, as well as an age-based subgroup analysis. ResultsThere was a medium effect of ED diagnosis on executive functioning, with bulimia nervosa demonstrating a larger effect (Hedges’s g = −0.70) than anorexia nervosa ( g = −0.41). Within anorexia nervosa studies, subgroup analyses were conducted for age and diagnostic subtype. The effect of anorexia nervosa on EF was largest in adults; however, subgroup differences for age were not significant. ConclusionsAnorexia and bulimia nervosa are associated with EF deficits, which are particularly notable for individuals with bulimia nervosa. The present analysis includes recommendations for future studies regarding study design and EF measurement. 相似文献

Background and objectivesThe majority of people with eating disorders (ED) experience high levels of comorbid anxiety and depression, yet the maintenance processes of these in ED remain largely unknown. Worry, a defining cognitive feature and important maintenance factor of anxiety, has not been well-studied amongst people with ED. This is the first study to explore both the process and content characteristics of catastrophic worry in ED. MethodsTwenty-nine patients with anorexia nervosa (AN), 15 patients with bulimia nervosa (BN) and 37 healthy controls (HC) completed measures assessing anxiety, depression, worry and eating disorder pathology. Catastrophic worry was assessed using the Catastrophizing Interview and catastrophic worry content was explored using qualitative Thematic Analysis. ResultsCompared to HCs, ED groups had higher levels of anxiety, depression and worry and they generated a greater number of catastrophic worry steps. Worry was further found associated with depressive symptomatology in those with ED. Worry content for the ED groups included ED themes, but also themes reflecting broader inter and intrapersonal concerns. LimitationsThe degree to which worry is driven by depressive versus anxious symptomatology remains unclear. The current study does not include an anxious or depressed control group, and results should be considered in the light of relatively small samples sizes. ConclusionFindings indicate that interventions that target worry processes may be a useful adjunct to treatment for those ED patients with clinical worry levels. 相似文献
