Também associa-se a outras patologias como transtorno de ansiedade, comportamento compulsivo e desequilíbrio no comportamento do sono. Apesar da obesidade ser considerada uma patologia previnível, ainda existem grandes dificuldades associadas com a perda de peso e a sua manutenção através da modificação do estilo de vida no cenário atual, mostrando a necessidade de investigação de fatores que abordem não só o peso, mas também patologias e/ou sintomas associados. A terapia floral faz parte de um campo emergente de terapias vibracionais, e suas essências, feitas a partir de plantas silvestres, flores e árvores do campo, atuam harmonizando as emoções, e não tratando de condições físicas. Neste contexto, aparece como uma alternativa para o alivio do comportamento ansioso dos indivíduos, pois não há incompatibilidade com outros métodos de tratamento, e pode ser indicada a um grande número de pessoas em qualquer etapa da vida. Objetivo: Identificar se o tratamento com terapia floral altera o grau de ansiedade de indivíduos com sobrepeso ou obesidade, com consequente melhora no padrão de sono, redução nos sintomas de compulsão alimentar, redução na frequência cardíaca de repouso e melhora nos níveis de pressão arterial. Métodos: Ensaio Clínico Randomizado, paralelo, com dois braços, duplo cego, placebo-controlado, de quatro semanas, realizado em uma instituição pública do estado de São Paulo - Brasil. Os participantes foram indivíduos sadios de ambos os sexos, com idade de 20 a 59 anos, alfabetizados, com sobrepeso ou obesidade pelos critérios da Organização Mundial da Saúde (IMC ≥ 25 Kg/m2) e com ansiedade moderada ou elevada pelos critérios do Inventário de Ansiedade-Estado (IDATE com Escore ˃ 34). Para a coleta de dados utilizou-se questionário sócio-demográfico e clínico, escala de ansiedade IDATE-ESTADO, Escala de Compulsão Alimentar Periódica (ECAP) e Questionário de Padrão do Sono de Pittsburg (PSQI), aferição da pressão arterial e eletrocardiograma, no momento inicial e após 4 semanas de tratamento. A análise estatística foi realizada calculando o delta para expressar a diferença das médias das medidas de desfecho entre os momentos de avaliação dentro de cada grupo estudado. Em seguida, utilizou-se o Teste de Mann-Whittney para a comparação entre grupos. Análise multivariada foi realizada utilizando modelos de regressão linear robusta simples e múltipla. Resultados: A coleta de dados ocorreu entre setembro de 2015 e janeiro de 2017 e a amostra foi constituída por 40 participantes no grupo placebo e 41 no grupo floral, principalmente pelo sexo feminino (92,5% e 90,2%), com idade média de 42,9 e 38,5 anos e IMC médio de 34,31 e 33,5 kg/m2 nos grupos placebo e floral respectivamente. A análise multivariada mostrou redução estatisticamente significante no grupo floral quando comparado ao grupo Placebo nas seguintes variáveis: IDATE (β=-0,190; p<0,001), PSQI (β=-0,160; p=0,027), ECAP (β=-0,226; p=0,001) e frequência cardíaca de repouso (β=-0,07; p=0,003). Conclusão: indivíduos tratados com terapia floral apresentaram redução de sintomas ansiosos, melhora no padrão de sono, redução nos sintomas de compulsão alimentar e diminuição na frequência cardíaca de repouso maior do que aqueles tratados com placebo. Esse resultado evidencia a importância e a necessidade de ações de saúde em prol da redução da ansiedade e sintomas associados em indivíduos com sobrepeso ou obesidade e fortalece a terapia floral como prática integrativa e complementar na área da saúde. / Introduction: The prevalence of obesity is increasing among adults worldwide and is associated with an increased risk of morbidity and mortality, as well as a reduction in life expectancy with negative health outcomes. It is also associated with other pathologies such as anxiety disorder, compulsive behavior and imbalance in sleep behavior. Although obesity is considered a predictable pathology, there are still great difficulties associated with weight loss and its maintenance by modifying lifestyle in the current scenario, showing the need to investigate factors that address not only weight but also pathologies and / or associated symptoms. Floral therapy is part of an emerging field of vibrational therapies, and its essences, made from wild plants, flowers and field trees, work by harmonizing emotions, not by treating physical conditions. In this context, it appears as an alternative for the relief of the anxious behavior of individuals, as there is no incompatibility with other treatment methods, and can be indicated to a large number of people at any stage of life. Objective: To identify whether treatment with floral therapy changes the degree of anxiety of overweight or obese individuals, with consequent improvement in sleep pattern, reduction in binge eating symptoms, reduction in resting heart rate and improvement in blood pressure levels. Methods: Randomized, parallel, two-arm, double-blind, placebo-controlled, four-week clinical trial conducted at a public stitution in the state of São Paulo - Brazil. Participants were healthy individuals of both sexes, aged 20-59 years, literate, overweight or obese according to World Health Organization criteria (BMI ≥ 25 kg / m2) and with moderate or high anxiety according to the criteria of the State - Trait Anxiety Inventory (STAI) (STAI with Score ˃ 34). Data were collected using a sociodemographic and clinical questionnaire, State - Trait Anxiety Inventory (STAI), Binge-Eating Scale (BES) and Pittsburgh Sleep Quality Index (PSQI), blood pressure and electrocardiogram and after 4 weeks of treatment. Statistical analysis was performed by calculating the delta to express the difference of means of outcome measures between the moments of evaluation within each group studied. Then, the Mann-Whittney test was used for the comparison between groups. Multivariate analysis was performed using simple and multiple robust linear regression models. Results: Data collection occurred between September 2015 and January 2017, and the sample consisted of 40 participants in the placebo group and 41 in the floral group, mainly female (92.5% and 90.2%), with age mean of 42.9 and 38.5 years and mean BMI of 34.31 and 33.5 kg / m2 in the placebo and floral groups, respectively. The multivariate analysis showed a statistically significant reduction in the floral group when compared to the placebo group in the following variables: IDATE (β = -0.190, p <0.001), PSQI (β = -0.160, p = 0.004), ECAP (β = -0.226; p = 0.001) and resting heart rate (β = -0.07, p <0.001). Conclusion: Individuals treated with floral therapy had reduced anxiety symptoms, improved sleep patterns, reduced binge eating symptoms, and decreased resting heart rate greater than those treated with placebo. This result evidences the importance and necessity of health actions in favor of the reduction of anxiety and associated symptoms in overweight or obese individuals and strengthens floral therapy as an integrative and complementary practice in the health area.

Está bem estabelecido que o Transtorno Alimentar (TA), uma patologia predominantemente compulsiva, e o Transtorno de Déficit de Atenção/Hiperatividade (TDAH), uma patologia predominantemente impulsiva, coocorrem em uma frequência maior do que esperado ao acaso. A avaliação fenotípica e o estudo detalhado de pacientes que apresentam ambas as patologias (TA-TDAH) oferecem a oportunidade de compreender melhor o tipo de interação entre esses dois traços comportamentais, fundamentais no entendimento das patologias dos comportamentos aditivos. Este é um estudo transversal com 63 mulheres com diagnóstico atual de Anorexia Nervosa (AN) ou Bulimia Nervosa (BN) recrutadas do Programa de Transtorno Alimentar do Hospital de Clínicas de Porto Alegre e 254 mulheres com diagnóstico de TDAH provenientes do Programa de Déficit de Atenção e Hiperatividade do mesmo hospital, entre os anos de 2002 e 2016. A coocorrência TA-TDAH foi diagnosticada em ambos os grupos através de entrevista clínica e instrumentos validados. A partir destes achados, o grupo TA-TDAH foi comparado em termos de perfil demográfico, sintomatologia clínica e comorbidades psiquiátricas, com sua contraparte com TDAH e sem TA e com TA sem TDAH. Nossos resultados mostraram que os indivíduos com TA-TDAH apresentam aumento da prevalência de transtorno de ansiedade generalizada e transtorno obsessivo compulsivo quando comparado ao grupo com TDAH. Ainda, o grupo de TATDAH apresenta aumento das taxas de comorbidades com uso de substâncias psicoativas (SPA) e uso de bebida alcoólica quando comparados com ambos os grupos, TA e TDAH. Este aumento excedeu o efeito meramente aditivo encontrado no padrão para as comorbidades inicialmente descritas, demonstrando um padrão sinérgico, resultante provavelmente da interação entre os comportamentos compulsivos e impulsivos. Se considerando a avaliação de funcionalidade, o grupo TDAH-TA apresentou piores escores nas áreas de lazer quando comparado ao grupo TDAH e nas áreas de finanças e cognição quando comparado ao grupo com TA. Estes resultados são relevantes clinicamente pois demonstram que a coocorrência de TA e TDAH está associada ao desenvolvimento de um perfil clínico mais severo, que provavelmente exija uma abordagem diferenciada para este tipo de paciente. / It is well established that an Eating Disorder is a predominantly compulsive pathology, and that the Attention Deficit Hyperactivity Disorder (ADHD) is a predominantly impulsive pathology, which occur at a frequency deemed higher than what one would expect for events occurring at random. The phenotype assessment and the detailed study of patients diagnosed with both pathologies provide us with the opportunity to better understand the type of interaction between these two behavioral traits, which are essential to the understanding of the pathologies related to addictive behaviors. This is a cross-sectional study involving 63 women who have been currently diagnosed with Anorexia Nervosa (AN) or Bulimia Nervosa (BN), recruited from the Eating Disorder Program at Hospital das Clínicas de Porto Alegre, was well as 254 women diagnosed with ADHD from the Attention Deficit Hyperactivity Disorder Program at the same hospital, carried out between 2002 and 2016. From clinical interviews and the use of validated instruments, we have been able to attest the co-occurrence of Eating Disorders and ADHD in both groups. Then, from these findings, a comparison was made in terms of demographics, clinical symptomatology and psychiatric comorbidities: the group diagnosed with an Eating Disorder and ADHD with the group diagnosed with ADHD without an Eating Disorder and the group with an Eating Disorder without ADHD. Our results have shown that individuals with an Eating Disorder and ADHD have presented higher numbers of generalized anxiety disorder and obsessive-compulsive disorder, when compared to the group diagnosed solely with ADHD. Moreover, the group diagnosed with an Eating Disorder and ADHD presented an increase in comorbidity rates with the use of psychotropic drugs and alcohol, when compared to the groups diagnosed solely with an Eating Disorder or ADHD. This increase has exceeded the purely addictive effect found in the patterns related to the comorbidities initially described, showing a synergistic pattern, most likely resulting from the interaction between compulsive and impulsive behaviors. When taking into account the assessment of functionality, the group diagnosed with an Eating Disorder and ADHD presented the lowest numbers in leisurely areas, when compared to the group diagnosed solely with ADHD, and the lowest number in financial and cognitive areas, when compared to the group diagnosed solely with an Eating Disorder. These results are relevant from a clinical standpoint, since they demonstrated that the co-occurrence of an Eating Disorder and ADHD is linked to the development of a more serious clinical profile, which will likely demand a unique approach towards these patients.

Todavia, é escassa a literatura que explore esse tipo de intervenção. O objetivo do presente estudo foi avaliar a eficácia do programa “O Corpo em Questão” nos fatores de risco para Transtornos Alimentares, em mulheres jovens adultas brasileiras. A intervenção foi realizada por meio de um Ensaio Clínico Controlado e Randomizado. A amostra foi composta por 141 mulheres universitárias, com idade entre 18 e 30 anos, matriculadas nos cursos superiores e técnicos do Instituto Federal de Educação, Ciência e Tecnologia do Sudeste de Minas Gerais – Campus Barbacena (IF Sudeste MG). As participantes foram aleatorizadas em dois grupos: Grupo Controle (n = 78; idade: M = 21,14 e DP = 2,57) e Grupo Intervenção (n = 63; idade: M = 20,33 e DP = 1,76). A intervenção consistiu em uma sessão semanal de 60 minutos, durante 4 semanas consecutivas, em grupos fixos de 5 a 8 participantes. Os instrumentos utilizados foram questionários e escalas autoaplicadas, que avaliaram a insatisfação corporal das estudantes, a influência da mídia, dos pais e amigos na Imagem Corporal, a internalização do ideal de magreza, os sintomas para Transtornos Alimentares, a apreciação corporal, os sintomas depressivos e a autoestima. Os questionários foram aplicados em momentos diferentes: antes de começar a intervenção, imediatamente após o fim da intervenção e no seguimento de 1 mês e 6 meses. Para a análise estatística deste estudo foi realizada a ANOVA para medidas repetidas com efeitos mistos para verificar se o Grupo Intervenção obteve reduções significantemente maiores que o Grupo Controle nas variáveis avaliadas em relação à linha de base. Foram feitas análises separadas para cada variável, considerando a relação entre sujeitos (controle × intervenção) e em 4 níveis (pré, pós-teste, seguimento de um mês e seis meses). Para verificar a interação Grupo × Tempo significantes, foram realizados os testes de seguimento, através da ANOVA de medidas repetidas, adotando-se 4 níveis para o Grupo Intervenção e Grupo Controle. A ANOVA de um fator foi utilizada somente nos casos em que houve diferença entre o Grupo Intervenção e o Grupo Controle nos 4 momentos. Os resultados indicaram diferenças significantes entre o grupo submetido à intervenção e controle, na insatisfação corporal, influência sociocultural da mídia, internalização do ideal de magreza, atitudes alimentares inadequadas, sintomas depressivos e um aumento da autoestima das mulheres submetidas à intervenção. Os efeitos da intervenção nas variáveis que apresentaram interação Grupo × Tempo significante variaram de r = 0,17 a 0,33, indicando a eficácia do programa na população de mulheres jovens. Concluiu-se que a intervenção “O Corpo em Questão” é um programa válido para prevenir diversos fatores de risco para Transtornos Alimentares em mulheres jovens brasileiras. / Eating disorders are disturbances in the alimentary behavior that lead to deleterious consequences to the individual´s health. Preventive intervention development to reduce risk factors is, therefore, needed. Aiming at to bridge this gap on intervention research in the national literature, the present study evaluates the efficacy of the program, "The Body in Question", upon risk factors for Eating Disorders in Brazilian young adult women. The intervention was performed through a Controlled and Randomized Clinical Trial. The sample comprised 141 university women, aged between 18 and 30 years, enrolled in the graduated and technical courses of the Federal Institute of Education, Science and Technology of the Southeast of Minas Gerais – Campus Barbacena (IF Sudeste MG). The participants were randomized into two groups: Control Group (n = 78; age: M = 21,14 e SD = 2,57) and Intervention Group (n = 63; age: M = 20,33 e SD = 1,76). The intervention consisted of a weekly session of 60 minutes, for 4 consecutive weeks, in fixed groups of 5 to 8 participants. The instruments used were self-administered questionnaires and scales, which assessed the students' body dissatisfaction, the influence of the media, parents and friends in Body Image, the internalization of the thinness ideal, symptoms for Eating Disorders, body appreciation, depressive symptoms and self-esteem. The questionnaires were applied at different times: before starting the intervention, immediately after the end of the intervention and in the follow-up of 1 month and 6 months. The statistical analysis applied ANOVA for repeated measures with mixed effects to verify if the Intervention Group obtained significantly greater reductions than the Control Group in the variables evaluated in relation to the baseline. Separate analyzes were performed for each variable, considering the relationship between subjects (control × intervention) and in 4 levels (pre, post-test, one month and six-month follow-up). To verify the Group × Time significant interaction, the follow-up tests were performed through repeated measures ANOVA, adopting 4 levels for the Intervention Group and Control Group. One-way ANOVA was used only in cases where there was a difference between the Intervention Group and the Control Group in the 4 moments. The results indicated significant differences between the group submitted to intervention and control, body dissatisfaction, socio-cultural influence of the media, internalization of the thinness ideal, inadequate eating attitudes, depressive symptoms and an increase in the self-esteem of the women submitted to the intervention. The effects of the intervention on the variables that presented significant Group × Time interaction ranged from r = 0.17 to 0.33, indicating the efficacy of the program in the population of young women. It was concluded that the intervention "The Body in Question" is a valid program to prevent several risk factors for Eating Disorders in young Brazilian women.

Rapid response is considered the most well-established outcome predictor across treatments of binge-eating disorder (BED), including cognitive-behavioral therapy (CBT). This study sought to identify latent trajectories of early change in CBT and compare them to common rapid response classifications. In a multicenter randomized trial, 86 adults with BED (DSM-IV) or subsyndromal BED provided weekly self-reports of binge eating over the first 4 weeks of CBT, which were analyzed to predict binge eating, depression, and body mass index at posttreatment, 6-, and 18-month follow-up. Using latent growth mixture modeling, three patterns of early change—including moderate and low decreasing—as well as low stable binge eating were identified, which significantly predicted binge-eating remission at 6-month follow-up. Other classifications of rapid response based on Receiver Operating Characteristics curve analyses or on the literature (≥ 10% reduction in binge eating at week 1, ≥ 70% reduction in binge eating at week 4) only predicted posttreatment remission or overall depression, respectively. Latent change trajectories, but not other rapid response classifications, predicted binge-eating frequency over time. A fine-grained analysis of change over the first 4 weeks of CBT for BED revealed different trajectories of early change in binge eating that led to an improved prediction of binge-eating outcome, compared to that of common rapid response classifications. Thorough monitoring of early change trajectories during treatment may have clinical utility.

To evaluate psychological treatments for adolescent binge-eating disorder (BED), reliable information on therapeutic process factors is needed. This study examines therapist adherence and therapeutic alliance and their associations in cognitive-behavioural therapy (CBT) for adolescents with BED. In a randomised-controlled efficacy trial, adherence and alliance were objectively determined based on 247 audio-taped CBT sessions from a sample of N = 64 adolescents with BED. Variability of adherence and alliance, explained by treatment module, patient, and therapist were examined using multilevel modeling. Although adherence and alliance were excellent and unaffected by treatment module and therapist, there was significant between-patient variability for both concepts. Adherence was negatively associated with patient's treatment expectation. Alliance was negatively associated with the number of loss of control eating episodes and positively associated with adherence. Excellent adherence supported the internal validity of CBT for adolescent BED. Associations between process factors and patient characteristics demand adequate supervision in CBT.

To provide a comprehensive meta-analysis on the efficacy of psychological and medical treatments for binge-eating disorder (BED), including those targeting weight loss. Method: Through a systematic search before March 2018, 81 published and unpublished randomized-controlled trials (RCTs), totaling 7,515 individuals with BED (Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition [DSM–IV] and Fifth Edition [DSM–5]), were retrieved and analyzed using random-effect modeling. Results: In RCTs with inactive control groups, psychotherapy, mostly consisting of cognitive-behavioral therapy, showed large-size effects for the reduction of binge-eating episodes and abstinence from binge eating, followed by structured self-help treatment with medium-to-large effects when compared with wait-list. Pharmacotherapy and pharmacological weight loss treatment mostly outperformed pill placebo conditions with small effects on binge-eating outcome. These results were confirmed for the most common treatments of cognitive-behavioral therapy, self-help treatment based on cognitive-behavioral therapy, and lisdexamfetamine. In RCTs with active control groups, there was limited evidence for the superiority of one treatment category or treatment. In a few studies, psychotherapy outperformed behavioral weight loss treatment in short- and long-term binge-eating outcome and led to lower longer-term abstinence than self-help treatment, while combined treatment revealed no additive effect on binge-eating outcome over time. Overall study quality was heterogeneous and the quality of evidence for binge-eating outcome was generally very low. Conclusions: This comprehensive meta-analysis demonstrated the efficacy of psychotherapy, structured self-help treatment, and pharmacotherapy for patients with BED. More high quality research on treatments for BED is warranted, with a focus on long-term maintenance of therapeutic gains, comparative efficacy, mechanisms through which treatments work, and complex models of care.

Objective Although avoidant/restrictive food intake disorder (ARFID) has been included as a new diagnostic entity of childhood feeding and eating disorders, there is a lack of measures to reliably and validly assess ARFID. In addition, virtually nothing is known about clinical characteristics of ARFID in nonclinical samples. Method The present study presents the development and validation of an ARFID module for the child and parent version of the Eating Disorder Examination (EDE) in a nonclinical sample of N = 39 children between 8 and 13 years with underweight and/or restrictive eating behaviors. For evaluating the ARFID module's reliability, the convergence of diagnoses between two independent raters and between the child and parent module was determined. The module's validity was evaluated based on the full-length child version of the EDE, a 24 h food record, parent-reported psychosocial functioning and self-reported quality of life, and objective anthropometric measures. Results In total, n = 7 children received an ARFID diagnosis. The ARFID module showed high interrater reliability, especially for the parent version, and high convergence between child and parent report. Evidence for the module's convergent, divergent, and discriminant validity was provided. Specifically, children with versus without ARFID reported significantly less macro- and micronutrient intake and were more likely to be underweight. Discussion This pilot study indicates the child and parent version of the EDE ARFID module to be promising for diagnosing ARFID in a structured way but still necessitates a validation in a larger clinical and community-based sample.

Binge-eating disorder (BED) is characterized by recurrent objective binge eating that occurs in the absence of compensatory behaviors to prevent weight gain. As the most common eating disorder emerging in youth, BED co-occurs with increased eating disorder and general psychopathology, impaired quality of life, and obesity [1]. Despite its clinical significance, there is a dearth of treatment studies in adolescents [1, 2]. Regarding cognitive-behavioral therapy (CBT), the most well-established treatment for adults with BED [2], one pilot randomized-controlled trial (RCT) in 25 adolescent girls with objective binge eating suggested superiority to wait-list (WL) in achieving binge-eating abstinence through 6 months following randomization and in improving eating disorder psychopathology, but not in reducing binge eating or standardized body mass index (BMI; kg/m2) [3]. Other CBT-related RCTs documented efficacy of Internet-based, weight loss-oriented self-help versus WL [4] and no differences in dialectical behavior therapy versus weight management [5]. Based on this preliminary evidence, the aim of the BEDA (Binge Eating Disorder in Adolescents) study was to provide a confirmatory test of the efficacy of CBT in adolescent BED. It was hypothesized that CBT will be superior to WL in improving binge eating, associated psychopathology, and quality of life, but not BMI, with long-term maintenance of effects.

Die vorliegende Arbeit entwickelt einen Vorschlag für einen neuen, kompakteren Fragebogen mit dem Akronym „BaFEK-45“ zur Diagnostik von Essstörungen, der auf einer statistischen Analyse von Daten aus fünf bereits etablierten Fragebogen (ANIS, EAT – 26, FBeK, EDI – 2, EDES) mit einer Gesamtzahl von 231 Items basiert. Dabei wurden die Antworten von Patientinnen aus den 1990er- und 2000er-Jahren der Klinik und Poliklinik für Psychiatrie, Psychotherapie und Psychosomatik des Kindes- und Jugendalters der Universität Leipzig ausgewertet. Auf Grundlage zweier „Signalfragen“ zu Ess-Anfällen wurden die Fragebogen-Serien in drei Gruppen (anorektisch, bulimisch und grenzwertig) eingeteilt, daraufhin konnte eine Analyse zu den Unterschieden im Antwortverhalten zwischen eben diesen Gruppe vorgenommen werden. Nach einem auf dieser Analyse basierenden Auswahlverfahren wurden die verbliebenen Items einer mehrstufigen Faktorenanalyse und kritischen inhaltlichen Differenzierung unterzogen. An deren Ende steht der o.g. Vorschlag eines neuen Diagnostikinstruments, das sich aus 45 Fragen in fünf Skalen zusammensetzt.

Objective: Loss of control (LOC) eating is a salient indicator of eating disorder psychopathology in adolescents and is associated with marked distress. While research has focused on the relevance of episode size, clinical significance of LOC eating frequency has rarely been explored. Therefore, this study aimed at identifying LOC eating prevalence with respect to its recurrence and associated variables in a community-based sample. Method: Participants were 1643 adolescents, aged 12-20 years (62.4% female). Based on EDE-Q self-report, participants were categorized as those reporting recurrent (N = 156; 9.5%), non-recurrent (N = 226; 13.8%) and no LOC eating (N = 1261; 76.7%). Results: Adolescents with recurrent LOC eating reported clinically relevant and significantly greater eating disorder psychopathology, functional impairment and distress because of LOC eating, and a significantly higher body mass index (BMI, kg/m2) than adolescents with non-recurrent and those without LOC eating. Discussion: These results underline that LOC eating is a common eating behavior among adolescents in the community associated with clinical characteristics of eating disorders, and could therefore be a risk factor for developing full- or partial-syndrome eating disorders. Further research on the classification of eating disorders in adolescents with LOC eating and severity indicators is warranted.
