Die Adipositas geht im Erwachsenenalter oft mit psychischer Komorbidität einher, die den Gewichtsreduktionserfolg beeinflussen und eine Behandlung indizieren kann, die von Standardprogrammen der multimodalen Adipositasverhaltenstherapie (AVT) nicht abgedeckt wird. Dieser Artikel diskutiert am Beispiel der häufig komorbiden Binge-Eating-Störung (BES) aktuelle Forschungsergebnisse zu Ätiologie und Intervention bei Komorbidität mit dem Ziel, Implikationen für die weitere Forschung und Behandlung abzuleiten. Weil die Kognitive Verhaltenstherapie (KVT), die am besten belegte Therapieform für Erwachsene mit BES, der AVT bei der Reduktion der Essstörungssymptomatik überlegen war, bei der Gewichtsreduktion nur tendenziell und ausschließlich kurzfristig unterlegen, sollte sich die weitere Interventionsentwicklung auf graduelle Anpassungen der KVT zur Verbesserung der Gewichtsreduktion bei Patienten mit Adipositas und BED konzentrieren. Hierfür kommen mit dem Ziel einer geringfügigen Gewichtsreduktion einzelne adaptierte AVT-Interventionen in Betracht, während sich gleichzeitige oder sequentielle Kombinationen dieser beiden Therapieformen nicht eindeutig bewährt haben. Interventionen, die auf aktuellen Forschungsergebnissen für die Komorbidität beider Störungsbilder fußen, könnten individualisiert einbezogen werden, um die Wirksamkeit für Essstörungssymptomatik und Körpergewicht zu erhöhen. Neue digitale Behandlungsmodalitäten könnten den Transfer in den Lebensalltag und die Nachhaltigkeit der Effekte fördern. Diese Modifikationen hin zu einer adaptiven KVT für Erwachsene mit Adipositas und BES, basierend auf einem patientengerechten Therapierationale, bedürfen der Absicherung durch weitere experimentelle Therapieforschung. / Obesity often co-occurs with mental comorbidity in adults, likely impacting weight loss success and indicating treatment that is not covered by standard behavioral weight loss (BWL) treatment. Using the example of binge-eating disorder (BED) as a frequent comorbid condition, this article discusses current research on etiology and intervention in case of comorbidity, in order to derive implications for research and treatment. Cognitive-behavioral therapy (CBT), the most well-established treatment for adults with BED, was more efficacious than BWL in improving binge-eating symptomatology in patients with obesity and BED, while tending to show lower weight loss effects in the short term only. Therefore, further intervention development should focus on gradual adaptations of CBT for improving weight loss. These interventions could be adapted from BWL and aim at a slight weight loss. Parallel or sequential combinations of these treatments have not consistently demonstrated improved treatment effects. Interventions based on current research could be included on an individual basis, in order to enhance efficacy for eating disorder symptomatology and body weight. New digital treatment modalities could support the transfer into daily life and boost the long-term maintenance of therapeutic gains. These modifications regarding adaptive CBT for adults with obesity and BED should be based on an individual treatment rationale and require further research in an experimental therapeutics framework.

Obesity prevalence continues to increase worldwide, yet few safe and effective treatment options are available suggesting there needs to be a greater emphasis on preventing rather than treating obesity. This research investigated the association of obesity predisposing SNPs and a gene score with nutrient consumption patterns including total energy intake and macronutrient distribution in a European ancestry population as well as discussing an evolutionary perspective on eating disorders using current epidemiological evidence to identify genes which may be involved. The association of two of the 14 obesity predisposing SNPs and the gene score with BMI was confirmed in the EpiDREAM population. Novel associations between two SNPs located in or near BDNF (rs6265 and rs1401635) were found with total fat, MUFA, and PUFA intake. Rs1401635 was also associated with total energy and trans fat intake. Novel associations of rs6235 (PCSK1) and the gene score were found with total energy intake. The novel associations found indicate that food related behaviours are one of the mechanisms of action through which obesity predisposing SNPs cause obesity and therefore warrant further investigation. The lack of association among all genes and the modest association of the gene score show that mechanisms other than food consumption are important. The investigation of the evolutionary history of eating disorders revealed that the adapted to flee famine hypothesis is a plausible theory explaining anorexia nervosa while the thrifty genotype hypothesis provides a possible explanation for bulimia nervosa and binge eating disorder. These evolutionary theories can be applied to identify new candidate genes as well as phenotypic traits to investigate to better understand the genetic architecture of eating disorders. Understanding genes associated with disordered eating patterns may highlight future areas for obesity prevention. / Thesis / Master of Science (MSc) / A large percentage of the risk of developing obesity or an eating disorder (anorexia nervosa, bulimia nervosa, and binge eating disorder) is determined by genetics. For obesity, many genes have been identified as influencing risk, but the mechanisms through which the genes work are largely unknown. For eating disorders, gene identification efforts have been mostly unsuccessful and no mechanisms of action have been determined. In the first component of this thesis we found an association between previously identified obesity risk genes and food intake, specifically the total number of calories consumed per day and the percentage of calories from total fat and fat subtypes. These results support that food related behaviours are possible mechanisms of action which need to be further investigated. In the second half of the thesis we viewed eating disorder behaviours from an evolutionary perspective. We concluded that there are theories that possibly explain eating disorder behaviours including being able to live off of small quantities of food as well as binging. These evolutionary theories can be applied to identify new genes to study in the context of eating disorders as well as different definitions of eating disorders.

Eating and feeding disturbances are prevalent yet understudied health conditions in youth. They are characterized by aberrant eating behaviors, cognitive and emotional dysfunctions, and dysregulated body weight. The Diagnostic and Statistical Manual of Mental Disorders Fifth Edition defines several feeding and eating disorders with a common onset in youth; however, data on their clinical validity at young ages are lacking. Further non-normative eating behaviors exist, but their clinical relevance needs elucidation. This Special Issue compiles state-of-the-art reviews and empirical research on the presentation, development, course, and maintenance of diverse eating and feeding disturbances as a prerequisite for delineating evidence-based interventions for treatment and prevention.

Objective: Analysis of short- and long-term effects of rapid response across three different treatments for binge-eating disorder (BED). Method: In a randomized clinical study comparing interpersonal psychotherapy (IPT), cognitive-behavioral guided self-help (CBTgsh), and behavioral weight loss (BWL) treatment in 205 adults meeting DSM-IV criteria for BED, the predictive value of rapid response, defined as ≥ 70% reduction in binge-eating by week four, was determined for remission from binge-eating and global eating disorder psychopathology at posttreatment, 6-, 12-, 18-, and 24-month follow-up. Results: Rapid responders in CBTgsh, but not in IPT or BWL, showed significantly greater rates of remission from binge-eating than non-rapid responders, which was sustained over the long term. Rapid and non-rapid responders in IPT and rapid responders in CBTgsh showed a greater remission from binge-eating than non-rapid responders in CBTgsh and BWL. Rapid responders in CBTgsh showed greater remission from binge-eating than rapid responders in BWL. Although rapid responders in all treatments had lower global eating disorder psychopathology than non-rapid responders in the short term, rapid responders in CBTgsh and IPT were more improved than those in BWL and non-rapid responders in each treatment. Rapid responders in BWL did not differ from non-rapid responders in CBTgsh and IPT. Conclusions: Rapid response is a treatment-specific positive prognostic indicator of sustained remission from binge-eating in CBTgsh. Regarding an evidence-based stepped care model, IPT, equally efficacious for rapid and non-rapid responders, could be investigated as a second-line treatment in case of non-rapid response to first-line CBTgsh.

Cette étude porte sur une intervention de groupe basée sur la thérapie cognitivo-comportementale pour l’hyperphagie boulimique (HB), dont les effets potentiels sur la qualité de vie reliée au poids, la fréquence et la sévérité des crises de boulimie, les symptômes dépressifs, l’image corporelle et le poids corporel ont été mesurés, et le degré d’acceptation par les participantes a été documenté. Ainsi, 11 femmes avec un surplus de poids et répondant aux critères diagnostiques de l’HB ont été recrutées du printemps 2012 à l’hiver 2013, dans la région de Montréal. Le programme comportant huit séances hebdomadaires était dispensé par une nutritionniste et une psychothérapeute. La qualité de vie reliée au poids (Impact of Weight on Quality of Life), la fréquence des crises de boulimie (rappel des sept derniers jours), la sévérité des crises de boulimie (Binge Eating Scale), les symptômes dépressifs (Inventaire de Beck pour la dépression), l’insatisfaction corporelle (Body Shape Questionnaire) et le poids corporel ont été mesurés avant et à la fin de l’intervention. Puis, un questionnaire pour mesurer l’acceptation par les participantes était soumis au terme du programme. Le taux de participation aux séances était aussi colligé. Les résultats montrent que notre programme a permis une amélioration significative du score global de la qualité de vie reliée au poids de 8,4 ± 13,3, ainsi qu’en termes d’estime de soi et de travail. Aussi, une diminution significative de la fréquence des crises de boulimie de 2,1 ± 2,1 jours, de la sévérité des crises de boulimie dont le score a diminué de 10,9 ± 7,7, des symptômes dépressifs dont le score a diminué de 8,3 ± 5,7 et de l’insatisfaction corporelle dont le score a diminué de 32,8 ± 17,1, ont été observées. Toutefois, il n’y a pas eu de perte de poids au terme de l’intervention. Puis, le programme a été bien accepté par les participantes tel que démontré par le taux de participation aux séances de 93,8 % et la satisfaction mesurée par l’appréciation des divers éléments du programme de 4,6 sur 5 et la pertinence de ceux-ci de 4,8 sur 5. Ces données suggèrent que l’intervention de groupe semble être prometteuse pour améliorer les symptômes et conséquences de l’HB, à l’exception du poids. / This study focuses on a group intervention for binge eating disorder (BED), by measuring its potential effects on the quality of life related to weight, frequency and severity of binge episodes, depressive symptoms, body dissatisfaction and body weight, and documenting the degree of acceptance of the intervention by the participants. Thus, 11 overweight women that met the BED diagnostic criteria were recruited from spring 2012 to winter 2013, in Montreal. The program includes eight weekly sessions based on Cognitive Behavioral Therapy provided by a nutritionist and a psychotherapist. Quality of life related to weight (Impact of Weight on Quality of Life), binge eating frequency (recall of the last seven days), binge eating severity (Binge Eating Scale), depression (Beck Inventory for depression), body dissatisfaction (Body Shape Questionnaire) and body weight were measured before and after the intervention. Then, a questionnaire to assess the acceptance by the participants was submitted at the end of the program. The rate of participation was also collected. The results showed that our program has resulted in significant improvements in the overall quality of life score related to weight of 8.4 ± 13.3, and in terms of self-esteem and work. We also observed a decrease in binge eating frequency by 2.1 ± 2.1 days as well as in binge eating severity, depressive symptoms and body dissatisfaction whose scores decreased by 10.9 ± 7.7, 8.3 ± 5.7 and 32.8 ± 17.1 respectively. However, there was no significant difference in weight at the end of the intervention. Also, the program was well accepted by the participants with a participation rate of 93.8%. Satisfaction and relevance of the program scored respectively 4,6 and 4,8 out of 5. These data suggest that the group intervention seems to be a promising method to improve the symptoms and consequences of HB, except for weight.

The issue of psychiatric co-morbidity is a serious public health problem occurring more and more frequently in the treatment of addiction and bringing with it various complications and often premature termination of treatment. The scoring system with a fixed set regime is still being used as the main instrument for treatment of addicted clients on the most specialized departments of psychiatric hospitals, although the effectiveness of the scoring system has not yet been clinically verified. The aim of this pilot study is to demonstrate and verify of the individual cases of clients with different categories of dual diagnosis, how they perceive the balance of the sanctions and rewards and fair setting in the context of the scoring system. Other goals are to find out and verify what is the influence of the scoring system on the motivation to change the behavior and success of treatment, what weaknesses clients with dual diagnosis perceive in this system and how they represent the treatment system, which would make them more fit and motivated to change behavior. Further, this study seeks to establish whether difficulties and obstacles on the way to stand up and go through the scoring system are different for individual dual diagnoses. A qualitative approach is used in the research part of the thesis....

INTRODUÇÃO: A obesidade na infância e adolescência representa uma epidemia global e figura como um problema de saúde pública proeminente de prevalência crescente. A obesidade frequentemente está associada à compulsão alimentar periódica (CAP) e componentes genéticos participam de sua etiologia multifatorial. Polimorfismos de nucleotídeo único (SNPs) no gene da leptina (LEP) e do receptor da leptina (LEPR) podem modificar a expressão da leptina e de suas vias de sinalização e, consequentemente, alterar a regulação do apetite e da saciedade, contribuindo assim para a etiopatogenia e manutenção da CAP. O objetivo deste trabalho foi investigar a influência dos polimorfismos rs7799039 (G > A) no gene LEP e rs1137100 (A > G), rs1137101 (A > G) e rs8179183 (G > C) no gene LEPR sobre a CAP em crianças e adolescentes obesos, além de caracterizar a população quanto à CAP e verificar a associação dos SNPs com o risco cardiometabólico (RCM) e a obesidade. MÉTODOS: Estudo transversal que incluiu 465 crianças e adolescentes obesos com idade entre 7 e 19 anos avaliados quanto a variáveis antropométricas e metabólicas. Os fatores de RCM consistiram de hipertensão arterial sistêmica, glicemia de jejum alterada, HDL-colesterol baixo e hipertrigliceridemia. A CAP foi avaliada por meio da Escala de Compulsão Alimentar Periódica (ECAP). Para investigar o efeito dos SNPs no risco para a obesidade foi incluído um grupo controle composto por 135 crianças e adolescentes eutróficos. A genotipagem foi realizada por PCR em tempo real e para análise dos SNPs, adotou-se o modelo dominante. Foi calculado o desequilíbrio de ligação entre os SNPs e estimada as frequências dos haplótipos. As comparações entre os grupos foram realizadas estratificadamente por gênero e estádio puberal. Para avaliar a magnitude do risco dos SNPs sobre a CAP e a obesidade foi realizada regressão logística ajustada para variáveis de confusão (idade, Z-IMC e estádio puberal). RESULTADOS: As crianças e adolescentes obesos (12,5 ± 2,9 anos; 52,7% meninas) classificados com CAP apresentaram maior adiposidade e a frequência da CAP foi mais elevada no gênero feminino (OR= 2,146; IC 95% 1,461-3,152; p < 0,001). A frequência do alelo A do rs7799039 foi mais elevada no grupo de obesos (OR= 1,530; IC 95% 1,022-2,292; p= 0,039) e o alelo associou-se ao maior nível de leptina e colesterol total em meninas e à maior glicemia em meninos (p < 0,05). No rs1137100 e o rs1137101, a presença do alelo G em meninas conferiu risco para a hipertrigliceridemia (OR= 1,926; IC 95% 1,010-3,673; p= 0,047 e OR= 2,039; IC 95% 1,057-3,931; p= 0,033, respectivamente). O alelo C do rs8179183 relacionou-se, em meninas, à relação cintura-estatura e glicemia mais elevadas e, em meninos, ao maior percentil de pressão arterial diastólica, glicemia, colesterol total e LDL-colesterol (p <0,05). CONCLUSÃO: Os polimorfismos não foram associados à compulsão alimentar periódica. A CAP foi relacionada ao pior grau de adiposidade e o maior risco foi observado no gênero feminino. O SNP rs7799039 no gene LEP conferiu risco para obesidade, enquanto o rs1137100, rs1137101 e rs8179183 no gene LEPR relacionaram-se ao pior perfil cardiometabólico em crianças e adolescentes obesos / INTRODUCTION: Obesity during childhood and adolescence represents a global epidemic and consists in a prominent public health issue of increasing prevalence. Obesity is frequently associated with binge eating (BE) and genetic factors participate of its multifactorial etiology. Single nucleotide polymorphisms (SNPs) in the leptin (LEP) and leptin receptor (LEPR) genes may modify the leptin expression and its signaling pathways and, consequently, alter appetite and satiety regulation, thus contributing to the etiopathogeny and maintenance of BE. The aim of this study was to investigate the influence of polymorphisms rs7799039 (G > A) in the LEP gene and rs1137100 (A > G), rs1137101 (A > G) and rs8179183 (G > C) in the LEPR gene on BE in obese children and adolescents, besides characterize the population regarding to BE and examine the association of SNPs with cardiometabolic risk (CMR) and obesity. METHODS: Cross-sectional study in which 465 obese children and adolescents aged from 7 to 19 years were enrolled and had anthropometric and metabolic variables assessed. The CMR factors consisted of systemic hypertension, impaired fasting glucose, low HDL-cholesterol levels and hypertriglyceridemia. The BE was evaluated through the Binge Eating Scale (BES). To investigate the effect of SNPs on obesity risk, a control group of 135 eutrophic children and adolescents was enrolled. Genotyping was performed by real-time PCR and for the SNPs analysis, the dominant model was adopted. The linkage disequilibrium between SNPs was calculated and the haplotype frequencies were estimated. Comparisons between groups were performed stratified by gender and pubertal stage. To assess the risk magnitude for the SNPs on BE and obesity, logistic regression adjusted for confounding variables (age, Z-BMI and pubertal stage) was performed. RESULTS: Obese children and adolescents (12.5 ± 2.9 years, 52.7% girls) classified with BE showed greater adiposity and BE frequency was higher among females (OR= 2.146; 95% CI 1.461-3.152; p < 0.001). The observed frequency of A allele of rs7799039 was a higher in the obese group (OR= 1.530; 95% CI 1.022-2.292; p= 0.039) and the allele was associated with higher leptin and total cholesterol levels in girls and higher glucose levels in boys (p < 0.05). For the rs1137100 and rs1137101, the presence of the G allele among girls, conferred risk for hypertriglyceridemia (OR= 1.926; 95% CI 1.010-3.673; p= 0.047 and OR= 2.039; 95% CI 1.057-3.931; p= 0.033, respectively). The C allele of rs8179183 was associated, among girls, with a higher waist-to-height ratio and glucose levels and, among boys, with greater diastolic blood pressure percentile, glucose, total cholesterol and LDL-cholesterol levels (p < 0.05). CONCLUSION: Polymorphisms were not associated with binge eating. BE was related with a more severe adiposity and an increased risk was observed among females. The SNP rs7799039 in the LEP gene contributed to the risk of obesity, whereas the rs1137100, rs1137101 and rs8179183 in LEPR gene were related to a worse cardiometabolic profile in obese children and adolescents

Introdução: O estado nutricional da gestante constitui importante fator para o desenvolvimento do feto e da gravidez saudável. Mulheres que apresentam ingestão inadequada de nutrientes têm maior probabilidade de desenvolver gestação de risco. Essa problemática é especialmente intensa quando a mulher apresenta quadro de transtorno alimentar (TA). Este trabalho abordou aspectos históricos, etiologia e epidemiologia dos TA, contemplou os critérios diagnósticos, concebeu os TA no período gravídico puerperal e dissertou sobre TA, sintomatologia ansiosa e depressiva. Os objetivos deste estudo foram determinar a prevalência de TA em gestantes com intercorrências clínicas e verificar a associação com sintomatologia ansiosa, depressiva e atitudes alimentares. Método: Estudo prospectivo transversal foi realizado com 913 gestantes com intercorrências clínicas que estavam no 2° ou 3° trimestre gestacional no ambulatório da Divisão de Clínica Obstétrica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Foi utilizada entrevista dirigida, para avaliação de picacismo; o EAT-26, para avaliar as atitudes alimentares; Structured Clinical Interview for DSM Disorders, para diagnóstico clínico de TA e a escala Hospital Anxiety and Depression, para análise da sintomatologia ansiosa e depressiva. Os dados deste estudo foram submetidos à análise quantitativa e avaliados por meio do programa IBM SPSS for Windows versão 20.0. Resultados: constatou-se prevalência de transtorno alimentar em 7,6% (n=69) (IC 95%: 5,84%-9,28%), sendo 0,1% (n=1), anorexia nervosa; 0,7% (n=6), bulimia nervosa; 1,1% (n=10), transtorno da compulsão alimentar e 5,7% (n=52), picacismo. Encontrou-se significância estatística quando associado TA com as variáveis: religião (p=0,02), abortamento provocado anterior (p < 0,01), tempo de relacionamento (p=0,01), renda per capita (p=0,04), número de gestações (p < 0,01) e número de filhos vivos (p < 0,01). Quanto às atitudes alimentares, observou-se significância estatística com \"sentir-se mal após comer doces\" (p=0,02) e \"passar muito tempo pensando em comida\" (p < 0,01). Constatou-se ainda associação positiva com sintomatologia ansiosa (p < 0,01) e com sintomatologia depressiva (p < 0,01). Conclusão: a prevalência de TA encontrada (7,6%) e sua associação com sintomatologia ansiosa e depressiva, durante a gestação, apontam para a necessidade de cuidados especializados no que diz respeito à prevenção, diagnóstico e tratamento. Dada a importância da alimentação adequada no período gestacional, tanto no que diz respeito à saúde materna, quanto ao desenvolvimento fetal, torna-se necessário implementar, pelos profissionais de saúde, avaliação específica com protocolo predeterminado para diagnóstico de TA no período gestacional / Introduction: The nutritional status of the pregnant woman represents an important factor for the development of the fetus and for a healthy pregnancy. Women who have inadequate nutrient intake are more likely to develop a risky pregnancy. This problem is particularly severe when the woman presents an eating disorder (ED). This paper discusses the historical aspects, etiology and epidemiology of ED, considers the diagnostic criteria, delineates ED in the puerperal pregnancy period and addresses ED, anxiety and depression symptoms. The aims of this study were to estimate the prevalence of ED in pregnant women with clinical complications and to assess the relationship between anxiety and depression symptoms and eating attitudes. Methods: A transversal and prospective study was conducted with 913 women between 2nd and 3rd trimester with high-risk pregnancies in the Obstetrics Clinic Division of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. We conducted structured interviews for the assessment of pica, Structured Clinical Interview for DSM Disorders for diagnostic of ED and Hospital Anxiety and Depression Scale for anxiety and depression symptoms, and applied the EAT-26 questionnaire for eating attitudes. The data analysis was quantitative and conducted with the IBM SPSS for Windows, version 20.0. Results: Lifetime prevalence of ED was 7.6% (n=69) (95% CI: 5.84%-9.28%), 0.1% (n=1) for anorexia nervosa; 0.7% (n=6) for bulimia nervosa; 1.1% (n=10) for binge eating disorder, and 5.7% (n=52) for pica. ED was statistically significant with respect to the following variables: religion (p=0.02), previous induced abortion (p < 0.01), being in a relationship (p=0.01), per capita income (p=0,04), number of previous pregnancies (p<0.01) and number of children (p < 0.01). For the eating attitudes, statistical significance was found with \"feeling ill after eating sweets\" (p < 0.02) and \"spend too much time thinking about food\" (p=0.05), as well as between ED and anxiety (p < 0.01) and depressive symptoms (p < 0.01). Conclusion: The prevalence of ED (7.6%) and its association with anxiety and depression symptoms during pregnancy highlights the need for specialist care for prevention, diagnosis and treatment. Given the importance of proper nutrition during pregnancy, both with regard to maternal health and fetal development, it is necessary to have specific predetermined evaluation protocols implemented by health care professionals for the diagnosis of ED during pregnancy

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.
