Research suggests that the associations between femininity, body image and eating disorders are intricate. How these constructs are linked to each other still needs to be determined. The purpose of this study was to gain a deeper understanding of these links, examining the mediational relationship among these constructs. Also, the prediction that bulimia and binge eating disorder symptoms have a similar origin was tested and compared. Some researchers have suggested that the pathways leading to these disorders are equivalent and the main difference between the two is the dietary restriction, while others see them as distinct disorders with different etiology. A total of 355 female college students (ages 18 to 26) completed a set of questionnaires that assessed femininity, feminine gender role stress, body dissatisfaction, bulimia, and binge eating disorder. Results showed that body dissatisfaction mediates the relationship between femininity or feminine gender role stress with bulimia symptoms, as well as the relationship between feminine gender role stress and binge eating disorder symptoms. Results indicate that body dissatisfaction related to femininity or to feminine gender role stress may contribute to higher levels of bulimia symptoms. The findings also suggest that body dissatisfaction related to feminine gender role stress may contribute to higher levels of binge eating disorder symptoms. Results did not support the mediational role of body dissatisfaction between femininity and binge eating disorder. However, the mediational role of feminine gender role stress between femininity and body dissatisfaction was partially supported, suggesting that feminine gender role stress might only be one pathway by which femininity may have an impact on body dissatisfaction. / Master of Science

Although evidence demonstrated efficacy of cognitive-behavioral therapy (CBT) in adolescents with binge-eating disorder (BED), treatment response is heterogeneous. This study uniquely examined baseline predictors of symptom trajectories in N = 73 adolescents (12–20 years) with an age-adapted diagnosis of BED (i.e., based on objective and subjective binge-eating episodes). Based on evidence from adult BED, dietary restraint, overvaluation of weight/shape, and depressive symptoms were used to predict changes in abstinence from binge eating and eating disorder psychopathology after 4 months of individual, face-to-face CBT using growth models. Longitudinal trajectories of abstinence from objective and subjective binge eating and global eating disorder psychopathology assessed via the Eating Disorder Examination were modeled for five time points (pre- and posttreatment, 6-, 12-, and 24-month follow-up). Beyond significant, positive effects for time, no significant predictors for abstinence from binge eating emerged. In addition to significant decreases in eating disorder psychopathology over time, higher pretreatment dietary restraint and overvaluation of weight/shape significantly predicted greater decreases in eating disorder psychopathology over time. Consistent with research in adult BED, adolescents with higher than lower eating disorder-specific psychopathology especially benefit from CBT indicating that restrained eating and overvaluation of weight/shape may be BED-specific prognostic characteristic across developmental stages. Future predictor studies with an additional focus on potential age-specific predictors, such as family factors, and within-treatment processes may be critical in further evaluating treatment-related symptom trajectories in adolescent BED.

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...

Während Leitlinien „Gold-Standards“ für die Psychotherapie bei bulimischen Essstörungen (Bulimia Nervosa und Binge-Eating-Störung) empfehlen, ist über psychotherapeutische Prozessfaktoren bei Essstörungen wenig bekannt. Ziel war es, mit Hilfe des etablierten Generic Model of Psychotherapy zur Systematisierung psychotherapeutischer Prozessfaktoren die aktuelle Literatur zum Einfluss dieser Faktoren auf den Therapieerfolg, operationalisiert als Symptomreduktion oder -remission, auf Basis einer systematischen Datenbanksuche zu sichten. Während der Einfluss des therapeutischen Settings nach bisheriger Forschungslage kaum Schlüsse hinsichtlich des Therapieerfolgs zulässt, konnte dieser durch spezifische Interventionen, frühe Symptomreduktionen und eine gute therapeutische Beziehung vorhergesagt werden. Weitere Forschung zu Prozessfaktoren bei bulimischen Essstörungen erscheint notwendig, um die praktische psychotherapeutische Arbeit zu unterstützen und Behandlungen effektiver gestalten zu können. / While guidelines recommend gold standards for psychotherapy in bulimic eating disorders (bulimia nervosa and binge eating disorder), less is known about psychotherapeutic process aspects. We aimed to summarize the current literature on the impact of process aspects on significant symptom reductions and/or abstinence as treatment outcome using the Generic Model of Psychotherapy. A systematic literature search was conducted. While effects of treatment settings can not yet be estimated, specific interventions, rapid response, and the therapeutic bond repeatedly predicted outcome. Process-outcome research in bulimic eating disorders will be necessary to support clinical practice and to enhance treatment efficacy.

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.

Die vorliegende Literatursichtung belegt, gerade im Lichte neuen Störungswissens und für neue diagnostische Kategorien, die Notwendigkeit, die Wirksamkeit bestehender Therapieformen zu erhöhen und/oder neue Behandlungen für Essstörungen, speziell für Bulimia Nervosa und Binge Eating-Störung, zu entwickeln. Ein wesentlicher Erkenntnisgewinn wird zudem von einer systematischen Analyse des therapeutischen Prozesses sowie von Moderatoren und Mediatoren erwartet. Darüber hinaus stellen die Dissemination evidenzbasierter Therapiemethoden in die Praxis und eine Überprüfung gestufter Behandlungsmodelle wichtige Aufgaben zukünftiger Forschung dar. / The consideration of existing literature, especially in light of new knowledge of eating disorders and new diagnostic categories, highlights the necessity to increase the efficacy of current forms of therapy, and to develop novel therapies for eating disorders. This pertains, in particular, to bulimia nervosa and binge eating disorder. A considerable gain in knowledge is to be expected from a systematic analysis of the therapeutic process as well as the moderators and mediators. Furthermore, dissemination of evidence-based treatment methods in practical settings and an examination of stepped care models are important avenues of future research.

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. Estudos têm sido realizados para analisar o perfil psicológico do paciente que será submetido à cirurgia bariátrica. Objetivo: Caracterizar pacientes com obesidade, candidatos à cirurgia bariátrica e identificar estilo de vida e a presença de sintomas de ansiedade, de depressão e de compulsão alimentar. Método: Estudo retrospectivo, realizado com base em dados de prontuários de pacientes em uma clínica particular do interior de São Paulo, candidatos à cirurgia bariátrica, avaliados pela psicologia, entre janeiro de 2010 e dezembro de 2015. A avaliação psicológica incluiu um questionário de dados pessoais, o Índice de Massa Corporal (IMC) fornecido pelo médico, o Inventário de Ansiedade de Beck (BAI), o Inventário de Depressão de Beck (BDI) e a Escala de Compulsão Alimentar Periódica (ECAP). Resultados: Foram analisados 188 prontuários. A idade variou de 16 a 65 anos (média 34,7; dp: 11,3), 73% (n=137) eram do sexo feminino, 48,4% (n=91) eram casados, e o IMC variou de 30 a 67 (média 42,8; dp: 6,5). Os resultados do BAI indicaram que 53% (n=100) tinham sintomas mínimos de ansiedade; do BDI que 52% (n=97) apresentaram sintomas de depressão de leve a severo; e do ECAP, que 26% (n=50) apresentaram compulsão alimentar. Conclusão: A maioria dos pacientes era do sexo feminino, sedentários, adultos jovens, com história de obesidade familiar e início da obesidade na infância. Hipertensão Arterial foi a comorbidade mais encontrada entre os participantes. Sintomas de ansiedade e depressão estiveram presentes, bem como compulsão alimentar.

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.

Introduction: Eating disorders are serious psychiatric disorders that often require specialized care. Associated psychiatric comorbidity is frequent, with the most common comorbid conditions being anxiety and mood disorders. Eriksbergsgården in Örebro is one of Sweden’s specialized eating disorder treatment units.Aim: Primary aims were to describe clinical characteristics of the adult patient group at Eriksbergsgården and to evaluate treatment outcome and patient satisfaction at the one-year follow-up. An additional aim was to examine if factors such as psychiatric comorbidity affected treatment outcome.Methods: This study used data from Riksät and Stepwise, two large-scale Swedish registers for eating disorder treatment. Data for this study was registered into Stepwise and Riksät at Eriksbergsgården between August 2010 and December 2017 and 489 adult patients of both genders constituted the study group. Patient characteristics and DSM-IV axis I psychiatric comorbidity were assessed at the initial evaluation. At the one-year follow-up, treatment outcome and patient satisfaction were evaluated.Results: The most common diagnoses in this patient material were eating disorder not otherwise specified, 56.6 %, followed by bulimia nervosa, 26.4 %. At the initial evaluation, 62.0 % of the patients suffered from psychiatric comorbidity. Of the patients with initial comorbidity, 43.3 % were recovered at the one-year follow-up, compared to 62.8 % of the patients with no initial comorbidity, p=0.021.Conclusion: Our results confirm the previously known fact that psychiatric comorbidity among eating disorder patients is common. Also, the results identify psychiatric comorbidity as a possible factor to have negative effect on the treatment outcome.
