Implicit cognitive processes in binge-eating disorder and obesity

Brauhardt, Anne, Rudolph, Almut, Hilbert, Anja 13 January 2017 (has links) (PDF)
Objectives: Binge-eating disorder (BED) is characterized by recurrent binge eating episodes, associated eating disorder and general psychopathology, and commonly occurs in obese individuals. Explicit self-esteem and explicit weight bias have been linked to BED, while little is known about implicit cognitive processes such as implicit self-esteem and implicit weight bias. Methods: Obese participants with BED and an individually matched obese only group (OB) and normal weight control group (CG; each N = 26) were recruited from the community to examine group differences and associations in explicit and implicit self-esteem and weight bias, as well as the impact of implicit cognitive processes on global eating disorder psychopathology. Implicit cognitive processes were assessed using the Implicit Association Test. Results: Significantly lower explicit self-esteem, as well as higher exposure to explicit weight bias, compared to CG and OB was found in the BED group. All groups showed positive implicit self-esteem, however, it was significantly lower in BED when compared to CG. BED and CG demonstrated equally high implicit weight bias whereas OB did not. Explicit and implicit measures were not significantly correlated. Global eating disorder psychopathology was predicted by explicit and implicit self-esteem. Conclusions: The results of the present study add to the importance of implicit self-esteem and implicit weight bias beyond explicit measures in BED, while both were previously shown to be associated with onset and maintenance of BED. In conclusion, implicit cognitive processes should be focused on in interventions for BED to investigate their impact on psychological treatments.

Cognitive and emotional functioning in BED

Kittel, Rebekka, Brauhardt, Anne, Hilbert, Anja January 2015 (has links)
Objective: Binge-eating disorder (BED) is characterized by recurrent episodes of binge eating and is associated with eating disorder and general psychopathology and overweight/obesity. Deficits in cognitive and emotional functioning for eating disorders or obesity have been reported. However, a systematic review on cognitive and emotional functioning for individuals with BED is lacking. Method: A systematic literature search was conducted across three databases (Medline, PubMed, and PsycINFO). Overall, n = 57 studies were included in the present review. Results: Regarding cognitive functioning, individuals with BED consistently demonstrated higher information processing biases compared to obese and normal-weight controls in the context of disorder-related stimuli (i.e., food and body cues), whereas cognitive functioning in the context of neutral stimuli appeared to be less affected. Thus, results suggest disorder-related rather than general difficulties in cognitive functioning in BED. With respect to emotional functioning, individuals with BED reported difficulties similar to individuals with other eating disorders, with a tendency to show less severe difficulties in some domains. In addition, individuals with BED reported greater emotional deficits when compared to obese and normal-weight controls. Findings suggest general difficulties in emotional functioning in BED. Thus far, however, investigations of emotional functioning in disorder-relevant situations are lacking. Discussion: Overall, the cross-sectional findings indicate BED to be associated with difficulties in cognitive and emotional functioning. Future research should determine the nature of these difficulties, in regards to general and disorder-related stimuli, and consider interactions of both domains to foster the development and improvement of appropriate interventions in BED.

Therapist adherence in individual cognitive-behavioral therapy for binge-eating disorder: assessment, course, and predictors

Brauhardt, Anne, de Zwaan, Martina, Herpertz, Stephan, Zipfel, Stephan, Svaldi, Jennifer, Friederich, Hans-Christoph, Hilbert, Anja January 2014 (has links)
While cognitive-behavioral therapy (CBT) is the most well-established treatment for binge-eating disorder (BED), little is known about process factors influencing its outcome. The present study sought to explore the assessment of therapist adherence, its course over treatment, and its associations with patient and therapist characteristics, and the therapeutic alliance. In a prospective multicenter randomized-controlled trial comparing CBT to internet-based guided self-help (INTERBED-study), therapist adherence using the newly developed Adherence Control Form (ACF) was determined by trained raters in randomly selected 418 audio-taped CBT sessions of 89 patients (25% of all sessions). Observer-rated therapeutic alliance, interview-based and self-reported patient and therapist characteristics were assessed. Three-level multilevel modeling was applied. The ACF showed adequate psychometric properties. Therapist adherence was excellent. While significant between-therapist variability in therapist adherence was found, within-therapist variability was non-significant. Patient and therapist characteristics did not predict the therapist adherence. The therapist adherence positively predicted the therapeutic alliance. The ACF demonstrated its utility to assess therapist adherence in CBT for BED. The excellent levels of therapist adherence point to the internal validity of the CBT within the INTERBED-study serving as a prerequisite for empirical comparisons between treatments. Variability between therapists should be addressed in therapist trainings and dissemination trials.

Poruchy příjmu potravy u mladých mužů / Eating Disorders in Young Men

Dražilová, Anna January 2020 (has links)
The diploma thesis is focusing on the topic of eating disorders in young men. The literature review summarizes the current information concerning eating disorders in this population. Eating and feeding disorders included in DSM - 5 are described. The thesis also focuses on orthorexia nervosa and muscle dysmorphia. A separate chapter deals with body image in men and its connection to eating disorders. The final chapter of the literary review section is focused on the possibilities of diagnostics and therapy. The empirical part of the work consists of a quantitative research conducted on a sample of 164 men aged 18-30 years. A questionnaire survey was carried out. Using Spearman's correlation coefficient, a significant correlation was found between the symptomatology of eating disorders and muscle dysmorphia. There was also a significant correlation between Body Mass Index and the symptoms of eating disorders and also between BMI and muscular dysmorphia. Data analysis revealed a positive correlation between the higher symptomatology of eating disorders and dissatisfaction with the amout of body fat. No significant relationship was found between the symptomatology of eating disorders and dissatisfaction with muscle mass. There was a significant correlation between Body Mass Index and dissatisfaction...

Childhood loss of control eating over five-year follow-up

Hilbert, Anja, Brauhardt, Anne 30 September 2016 (has links) (PDF)
Objective: Emerging prospective evidence from mixed samples, mostly covering short-term follow-up periods, suggests that childhood loss of control (LOC) eating predicts significant impairment in mental and physical health. This study sought to investigate the natural course of childhood LOC eating over the long term and in relation to binge eating disorder (BED) diagnosis, psychopathology, and body weight trajectory in the community. Method: A total of 60 children (8-13 years) with LOC eating within the past three months and 60 demographically-matched children without LOC history were assessed with the Eating Disorder Examination adapted for Children and self-report questionnaires over a 5.5 year follow-up period. Missing data were imputed. Results: Over follow-up, 38.3% of children showed persistent LOC eating, and 28.3% revealed an onset of LOC eating. Persistent LOC eating significantly predicted onset of partial-/full-syndrome BED at follow-up. Negative prognostic effects on eating disorder psychopathology, depressive symptoms, and body mass index were non-significant. Discussion: The results indicate a moderate stability of LOC eating over the long term. LOC eating, especially if stable, was suggested as a variable risk factor of clinically relevant eating disturbances. In contrast, a prognostic value for psychopathology and body mass index was not confirmed.

Intervenção interdisciplinar para prevenção de Diabetes Mellitus sob a perspectiva da psicologia: benefícios na qualidade de vida / Interdisciplinary Intervention for Prevention of Diabetes Mellitus under a Psychological Perspective: Benefits in Quality of Life

Cezaretto, Adriana 07 October 2010 (has links)
Introdução: O aumento da expectativa de vida e da prevalência de doenças crônicas, como o diabetes mellitus (DM), mudou o foco das agências governamentais de saúde. O DM causa complicações crônicas graves comprometendo a qualidade de vida (QV) e a sobrevida; em concomitância com transtornos psiquiátricos como depressão e compulsão alimentar periódica (CAP) piora adesão ao tratamento e deteriora o prognóstico. É possível que abordagem psicoeducativa reverta em melhor controle metabólico e QV por meio de programa de mudanças de hábitos de vida. Objetivo: Avaliar se intervenção no estilo de vida com abordagem intensiva interdisciplinar a indivíduos de risco para DM resulta em melhor QV que a intervenção tradicional (IT). Métodos: 177 indivíduos pré-diabéticos ou portadores de síndrome metabólica, atendidos pelo SUS, foram alocados aleatoriamente para uma IT ou intensiva (II) em hábitos de vida por 9 meses. O grupo de IT foi submetido a consultas médicas trimestrais e o grupo II, além destas, participou de 13 sessões de grupos psicoeducativos para mudanças em hábitos alimentares e atividade física. No momento basal e após 9 meses submeteram-se a exames clínico-laboratoriais e a questionários: versão longa do IPAQ, recordatórios alimentares de 24h, de QV (SF-36), para depressão (IBD e PRIME-MD) e escala de CAP. Fatores preditivos de adesão definida como participação em pelo menos 70 por cento das sessões psicoeducativas foram analisados em modelo de regressão logística. Resultados: Em ambas as intervenções houve melhora significante do IMC, circunferência abdominal e HDL. Após 9 meses, apenas os indivíduos da II reduziram pressão arterial e glicemia. O grupo II obteve melhora significante da QV na maioria dos domínios do SF-36 e nas medidas-resumo do componente físico e mental. Comparando os incrementos na QV induzidos pelas intervenções, foram maiores nos domínios capacidade física (II: 11,1±14,0 vs. IT: 5,3±13,0; p=0,02) e aspecto emocional (II: 20,4±40,2 vs. IT: 16,2±43,8; p=0,05) na II em relação à IT. As frequências de depressão reduziram em ambas as intervenções aos 9 meses, porém as de CAP diminuíram apenas na II (28,0 para 4,0 por cento, p<0,001; IT: 13,7 por cento para 8,6 por cento; p=0,38). As mudanças nos domínios do SF-36 se correlacionaram inversa e significantemente com os deltas do IMC, circunferência abdominal, pressão arterial sistólica e glicemia. Também se detectou correlação inversa dos escores de QV com os de depressão (r= -0,275; p=0,001) e de CAP (r= -0,175; p=0,043). Regressão logística mostrou que o sexo masculino associou-se independentemente à adesão à II (p=0,02), mas não a presença de CAP ou depressão. Conclusão: Intervenção no estilo de vida com abordagem interdisciplinar em indivíduos de risco para DM beneficia mais a QV que IT, em paralelo à melhora metabólica. O controle da CAP e depressão parecem contribuir para melhora da QV, mas não é preditivo de adesão a programa de II. Nossos achados indicam que intervenção interdisciplinar, ainda que não-direcionada à terapia de distúrbios psiquiátricos, pode auxiliar no controle da depressão e CAP e melhorar a QV / Introduction: Longer life expectancy and high prevalence rates of chronic diseases such as diabetes mellitus (DM) have modified the focus of government health agencies. DM causes severe chronic complications deteriorating quality of life (QoL) and survival; concomitance of DM and psychiatric disorders - such as depression and binge eating (BED) - decreases compliance to treatment and deteriorates prognosis. Management of these disorders may revert in better metabolic control and QoL during programs of lifestyle changes. Objective: To assess whether lifestyle intervention with intensive interdisciplinary approach for individuals at risk for DM results in better QoL that traditional intervention (TI). Methods: 177 individuals with pre-diabetes or metabolic syndrome, seen by Brazilian public health system, were randomly allocated to an IT or intensive intervention (II) in life habits for 9 months. Individuals from TI had medical visits each three months and from II additionally attended 13 psychoeducative group sessions focusing on dietary habits and physical activities. At baseline and after 9 months, they were submitted to clinical examination and laboratory procedures and answered questionnaires: long version of IPAQ, 24-h food recalls, QoL (SF-36), for depression (BDI and PRIME-MD) and binge eating scale. Predictors of compliance defined as attendance >70 per cent of group sessions were analysed by logistic regression. Results: In both interventions, significant improvements in body mass index, waist circumference and HDL-cholesterol levels were observed. After 9 months, only the individuals submitted to II had blood pressure and plasma glucose levels reduced. The same individuals had significant increases in almost all domains and summary measures of the SF-36. Comparing the induced increases in QoL, measures were greater in the domains of physical functioning (II: 11.1 ± 14.0 vs. IT: 13.0 ± 5.3; p = 0.02) and role-emotional (II: 20.4 ± 40.2 vs. IT: 16.2 ± 43.8; p = 0.05) in II in relation to IT. Frequencies of depression reduced in both interventions to 9 months, although of BED decreased only in II (28 to 4 per cent, p <0.001; IT: 13.7 per cent to 8.6 per cent, p = 0.38). Changes in SF-36 correlated inversely and significantly with differences of BMI, waist circumference, systolic blood pressure and glucose levels. Also found was as inverse correlation of QoL scores with depression (r = -0.275, p = 0.001) and BED (r = -0.175, p = 0.043). Logistic regression showed that male gender was independently associated with adherence to II (p = 0.02) but not the presence of BED or depression. Conclusion: Intervention in lifestyle with an interdisciplinary approach induced better benefits for QoL of individuals at risk for DM than the IT, as well as for metabolic profile. The decreased frequencies of the BED and depression following the II may contribute to improvement of QoL, but is not predictive of compliance. Our findings indicate that interdisciplinary intervention for prevention of DM, even not directed to psychiatric disorders, has extrametabolic effects, favoring the control depression and BED and improving QoL

There's a subgroup of individuals who have inadequate eating patterns and therefore, suffer from eating disorders. In this category, there are those who suffer from Binge Eating Disorder. The first symptoms usually appear during childhood o adolescence. This research investigates the psychic dynamics of teenagers who have Binge Eating symptoms by using the Rorschach Method. Seven participants who felt loss of control eating and had episodes of Binge Eating were selected based on the Questionnaire on Eating and Weight Patterns - Revised. These teenagers were interviewed and submitted to the Rorschach test. The analysis of the material collected based on these implements made it clear that there was a behavioral pattern. These adolescents have difficulties to confront their inner self and to deal with affection. Moreover, they have problems in socializing. The qualitative analysis of the answers given by the participants when exposed to the Rorschach figures have granted us a greater comprehension of the psychic dynamics involved when these symptoms are shown. A balking family environment - which fails to contribute to the building of a rich inner self -, and a negative maternal and/or paternal complexes are determinant to this condition. These adolescents are unable to acquire the necessary psychic conditions to face an intense period of change, such as the one which defines the turbulent teenage years. Thus, they strive to build an adequate persona capable of relating to the external world and the construction of a more integrated ego. These teenagers go through an empty period: they are incapable of going back on their development and remain in a safer environment, inside the Family scenery but also face a series of obstacles which are hari to overcome so that they car evolve. In this context, compulsive crisis is part of the equilibrium they manage to reach. By eating, they find the only confort and relief for their failures, for what the~ are unable to express and feel impotent to deal / A obesidade e as dificuldades envolvendo a alimentação podem ser consideradas, na sociedade atual, como uma pandemia. Há um subgrupo de indivíduos que possuem padrões inadequados de alimentação e que, portanto, sofrem de transtornos alimentares. Dentro dessa categoria, existem aqueles que sofrem de Transtorno de Compulsão Alimentar Periódica. Muitas vezes o inicio dos sintomas aparece ou na infância ou na adolescência. Essa pesquisa dedica-se à investigação da dinâmica psíquica dos adolescentes que apresentam sinfonias de compulsão alimentar através do método de Rorschach. Foram selecionados, a partir do Questionário sobre Alimentação e Peso Revisado, sete participantes que consideravam ter sensação de perda de controle sobre o que se come e episódios de compulsão alimentar. Esses adolescentes foram submetidos a uma entrevista e ao teste de Rorschach. A análise do material obtido a partir desses instrumentos possibilitaram o reconhecimento de um padrão de comportamento. Esses jovens enfrentam dificuldades no contato com o mundo interno e na modulação dos seus afetos. Além disso, possuem problemas no contato social. A análise qualitativa das respostas fornecidas pelos participantes às pranchas de Rorschach nos conduziram a uma maior compreensão do funcionamento psíquico envolvido no aparecimento desses sintomas. Um ambiente familiar falho, que não contribui para a formação de um mundo interno rico, um complexo materno e/ou paterno negativos, são determinantes para que eles não consigam as condições psíquicas necessárias para enfrentar um período de mudanças intensas como as que marcam a fase da adolescência. Com isso, ocorrem dificuldades na formação de uma persona adequada para se relacionar com o mundo externo e de um ego mais integrado. Esses adolescentes vivem um vazio: não conseguem voltar atrás no desenvolvimento e ficar em um ambiente mais protegido, dentro da família, mas também encontram uma série de obstáculos difíceis de transpor para que evoluam. Nesse contexto, as crises compulsivas fazem parte do equilíbrio que alcançam: encontram na comida o único conforto e alivio pelos fracassos, pelas coisas que não conseguem expressar e com as quais se sentem incapazes de lidar

Studies have been conducted to analyze the psychological profile of the patient who will undergo bariatric surgery. Objective: To characterize obesity patients, candidates for bariatric surgery and to identify lifestyle and the presence of symptoms of anxiety, depression and binge eating. Method: A retrospective study was carried out based on data from patients' charts in a private clinic in the interior of São Paulo, who were candidates for bariatric surgery, evaluated by psychology between January 2010 and December 2015. The psychological evaluation included a data questionnaire (BMI), the Beck Anxiety Inventory (BAI), the Beck Depression Inventory (BDI) and the Periodic Feed Compulsion Scale (ECAP). Results: 188 medical records were analyzed. Age ranged from 16 to 65 years (mean 34.7; SD: 11.3), 73% (n = 137) were female, 48.4% (n = 91) were married, and BMI ranged from 30 to 67 (mean 42.8; dp: 6.5). The BAI results indicated that 53% (n = 100) had minimal anxiety symptoms; of BDI that 52% (n = 97) presented symptoms of mild to severe depression; and ECAP, that 26% (n = 50) presented binge eating. Conclusion: Most of the patients were female, sedentary, young adults, with a history of family obesity and childhood obesity onset. Arterial Hypertension was the most common comorbidity among participants. Symptoms of anxiety and depression were present as well as binge eating. / Obesidade é uma doença crônica, multifatorial, que envolve questões psicológicas, genéticas e ambientais.

Efeitos de um modelo de oferta e retirada de dieta de cafeteria sobre o comportamento alimentar e ansiedade em ratas / Effects of a model of cafeteria diet supply and withdrawal on eating patterns and anxiety-like behavior in female rats

Raquel Lunardi Baccetto 24 February 2017 (has links)
A incidência global de obesidade tem aumentado nas últimas décadas e o consumo excessivo de alimentos industrializados ricos em açúcar e gordura está entre suas principais causas. Pesquisas recentes têm mostrado que estes alimentos desencadeiam mecanismos neurais e comportamentos semelhantes à adicção a drogas. Sabe-se que hábitos e preferências alimentares de adultos são adquiridos na infância, mas intervenções efetivas para prevenção da obesidade e suas comorbidades em crianças e adolescentes ainda constituem um desafio para a saúde pública. O objetivo do presente estudo foi avaliar os efeitos do consumo de dieta de cafeteria e retirada desta no comportamento alimentar, peso corporal, perfil lipídico, regularidade do ciclo estral, e comportamento de ansiedade e motivação. Ratas Wistar tiveram acesso limitado a itens alimentares de consumo humano de alta densidade energética por quatro semanas, ao final das quais foi realizada a retirada da dieta experimental de duas maneiras: para um grupo total e brusca, e para outro gradual durante uma semana. Após essa retirada, que simula dietas humanas de restrição, as ratas foram submetidas a testes comportamentais para avaliar ansiedade (labirinto em cruz elevado), e motivação para restabelecimento do acesso à dieta de cafeteria (modelo de restabelecimento). O grupo submetido à dieta de cafeteria apresentou maior consumo de gorduras totais e saturadas (p<0,05), e menor consumo de proteínas totais e fibras (p<0,05). Apesar disso, o consumo energético diário entre os grupos não atingiu diferença estatisticamente significativa, assim como o peso corporal das ratas. Após retirada da dieta de cafeteria, o consumo energético foi reduzido significativamente, porém, não acompanhado de perda de peso. Houve diferença significativa no perfil lipídico, sendo que ratas do grupo Cafeteria Sem Retirada tiveram os maiores valores de colesterol total e colesterol LDL (p<0,05). As ratas que sofreram retirada da dieta de cafeteria tiveram seus valores de colesterol similares às alimentadas somente com ração. A retirada completa da dieta de cafeteria e consequente diminuição do consumo energético foi responsável por irregularidade no ciclo estral das ratas. Os resultados no labirinto em cruz elevado não atingiram diferença estatisticamente significativa. O grupo Ração passou mais tempo no lado claro (p<0,05), conforme mostrado pelo teste de restabelecimento. A oferta limitada, de curto prazo, pós-desmame da dieta de cafeteria foi efetiva no desenvolvimento de compulsão alimentar em ratas adolescentes, porém sem evidências de vício alimentar. É provável que a obesidade seja condição necessária para o vício. Esperamos que os resultados deste estudo contribuam para o conhecimento da relação entre qualidade da dieta e comportamento alimentar e de adicção em ratas adolescentes. / The global incidence of obesity has steadily risen in the last decades and the excessive intake of industrialized food rich in sugar and fat is among its main causes. Recent researches have shown that these foods activate neural mechanism and behaviors similar to what is seen with drug addiction. It is known that adults eating habits and preferences are generally established during childhood, but effective preventive measures against obesity and its comorbities in children and adolescents are still a current public health challenge. The goal of the present study was to evaluate the effects of a cafeteria diet intake and withdrawal on eating behavior, body weight, lipid profile, estrous cycle regularity, and anxiety-like and motivational behavior. Female Wistar rats had limited access to energy-dense food items typically consumed by humans for four weeks, at the end of which, withdrawal from this diet occurred in one of two ways: for a group withdrawal was abrupt and total, and for another group, gradual for one week. After withdrawal, which attempts to mimic human restrictive dieting, we evaluated rats anxiety-like behavior through the elevated plus maze, and their motivation to reinstate access to the cafeteria diet through a reinstatement model. Daily energy intake between groups did not reach significant difference, as well as their body weight. Cafeteria fed rats did gain weight at a faster pace, and had a significant greater intake of total and saturated fat, and sodium (p<0.05); and a significantly lower intake of proteins and fibers (p<0.05). Groups that underwent withdrawal reduced their caloric intake significantly, but there was no weight loss. Rats with continuous access to cafeteria diet also had higher levels of total and LDL cholesterol (p<0.05), and rats from withdrawal groups had their cholesterol levels similar to chow-only animals. The total withdrawal of the cafeteria diet and resulting lower energy intake were also responsible for estrous cycle irregularities. There was no significant difference in rats performance in the EPM test. Chow only rats spent significantly more time in an aversive setting in order to gain access to an item from the cafeteria diet (p<0.05). The limited, short term, post-weaning offer of a cafeteria diet was effective in developing compulsive eating disorder, but without signs of food addiction. It is likely that obesity is precedent to the development of addiction. We expect that the results from this project contribute to the ongoing discussion and investigation on eating and addiction behavior in female adolescents rats.
