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.

The rural African American population has a high incidence of severe psychosocial problems and a skewed perception of obesity, despite obesity's extremely high prevalence rate in this population. Despite the acknowledgements of these problems, there is a gap in literature relative to the effective treatments for obese African Americans diagnosed with depression. This study measured correlations between obesity and depression, binge eating, and food culture amongst African American women residing in Jefferson County, MS. The health belief model was used to guide an assessment of beliefs, perceptions, susceptibility, cues to action, and self-efficacy. A cross-sectional design was used based on the sampling method and the associated sites along with distinctive design factors, including: no time factor, existing differences, and no random allocation. The Beck depressive inventory and the Bernice Roberts Kennedy cultural inventory for minority groups were the tools used to measure obesity and depression. Linear regression determined that there was an association between depression and obesity. Analyzation of study findings indicated that the participants responded to culturally sensitive questions surrounding prayer, religious involvement, and regular church attendance, which are common coping responses and mechanisms for depressed African American women. These results show a need to encourage health practitioners and researchers to create and implement individualized health promotion campaigns and interventions that fit with community and cultural realities, which could effectively address the obesity and poor health epidemic among rural African American women.

Binge-eating disorders are a common problem affecting up to 5 percent of the American population in any given 6-month period. Currently, the most widely accepted treatment is some variation of Cognitive Behavior Therapy. Although there is an abundance of research showing positive effects, the abstinence rates following this type of treatment are currently around 50%. A recent study by Bosch, Miltenberger, Gross, Knudson, and Brower-Breitwieser (2008) explored the effects of extinction on binge-eating behavior that was hypothesized to be maintained by relief from negative emotional responding. The study involved four women who engaged in binge-eating behavior, one of whom met the diagnostic criteria for Bulimia Nervosa. The treatment was successful, with three of the four participants obtaining abstinence. To date, this has been the only study examining this procedure and with only four participants. The purpose of the current study was to further evaluate extinction of binge eating maintained by automatic negative reinforcement with women who met diagnostic criteria for Bulimia Nervosa. Four young women enrolled in the study, three of whom met criteria for Bulimia Nervosa. The results showed that the treatment decreased binge eating to zero for all four women, although one dropped out of the study shortly after beginning the intervention.

Métodos: O estudo experimental foi composto de 3 grupos (n=23), sendo: grupo Eutrófico (GE;n=8), grupo obeso sem ECA (GO;n=7) e obesas com ECA (ECA;n=8). Todas as mulheres que participaram do estudo freqüentavam os serviços de saúde da Policlínica Piquet Carneiro. Foram dosados os hormônios: Grelina Total, Glucagon, Adiponectina, Amilina, Peptídeo C, GLP-1, Insulina e Leptina séricos nos tempos: jejum, 15 e 60 minutos após a ingestão da refeição fornecida. As refeições ingeridas foram controladas em energia, 55% carboidratos, 15% proteínas, 30% lipídios. Os dados foram analisados como valores médios por grupo em software SAS, considerando p<0,05. Resultados: A idade das mulheres estudadas variou de 32 a 50 anos. A concentração de adiponectina encontrada, que é inversamente proporcional a adiposidade, foi significativamente menor no grupo ECA em relação aos demais grupos (p=0,01). Em relação à leptina, o grupo GO apresentou concentração maior em relação aos demais grupos (p<0,0001). Já, a concentração de grelina encontrada foi significativamente menor no grupo ECA em relação aos demais grupos (p=0,02). Foram encontradas concentrações significativamente maiores de insulina no grupo GO em relação aos demais grupos (p=0,04). A concentração de amilina encontrada foi significativamente maior no grupo GO em relação aos outros grupos (p=0,01). A concentração de GLP-1 encontrada no grupo GO foi maior em média, porém esta diferença não foi estatisticamente significativa entre os grupos (p=0,25). A concentração de Peptídeo C encontrada no grupo GO foi maior em relação aos outros grupos (p=0,003). Apesar da concentração de Glucagon no grupo ECA ser maior em relação aos demais grupos, estes valores não eram diferentes estatisticamente (p=0,13). Nossos achados mostraram que obesas ECA tem perfil hormonal diferente de obesas sem ECA. A baixa concentração de grelina do grupo de obesas ECA e a alta concentração de insulina, peptídeo C e amilina nas obesas com e sem ECA pode estar relacionado com o aumento da ingestão alimentar e com o desequilíbrio energético. / Binge eating is associated to several diseases, including obesity. In order to study the hormonal control of hunger and satiety that is commonly involved in binge-eating process; we evaluated the serum concentration of these hormones in adult women. The experimental study was composed of 3 groups, n= 23: Lean (GE, n = 8), Obese without binge (GO, n = 7) and obese with binge (BEE, n = 8). All women who participated in the study attended the health services of the Polyclinic Piquet Carneiro. Serum hormones were assayed: total ghrelin, glucagon, adiponectin, Amylin, c-Peptide, glucagon like peptide (GLP-1), insulin and Leptin in fasting, 15 and 60 minutes after food intake. Meals were controlled in energy, 55% carbohydrates, 15% protein, 30% lipids. Data were analyzed as average values per group in SAS software, considering p <0.05. Results: Women`s age ranged from 32 to 50 years. The adiponectin concentration, which is inversely proportional to adiposity, was significantly lower in BEE group than the other groups (p=0.01). Leptin of the GO group presented higher concentration than the others (p<0.0001). Ghrelin concentration was significantly lower in BEE group than the other groups (p=0.02). We found a significantly higher concentration of insulin in GO group in comparison to the others (p = 0.04). Amylin concentration was significantly higher in GO group in comparison to the other groups (p=0.01). GLP-1 concentration of GO group was higher on average, but not statistically significant between groups (p=0.25). Cpeptide concentration found in GO group was higher than the others (p=0.003). Despite glucagon concentration in the BEE group was greater than the other groups, these values were not statistically different (p=0.13). Our findings shown that BEE group have different hormonal profile than GO and GE. The lowest concentration of ghrelin found in BEE group and the highest concentration of insulin, C-peptide and amylin found in both obese group with and without binge eating may be related to increased food intake and energy imbalance.

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.

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

Method: A cross-sectional populationbased study was carried out in the city of Pelotas, southern Brazil, with a sample of 2,097 individuals aged 20-59 years. BE was assessed through a questionnaire and defined as binging one or more times over the last three months before the interview. Results: The prevalence of BE and recurrent BE was 7.9% and 2.7%, respectively. In the adjusted analysis, obesity, fair/poor SRHS and body dissatisfaction remained strongly associated with BE. Discussion: This study showed a high prevalence of BE among adults in Pelotas, and its higher among younger women, fat and those who desire to weigh less. The current results are informative, but longitudinal studies would be needed to demonstrate the causal relationship between these events. / Objetivo: estimar a prevalência de episódios de compulsão alimentar (BE) e para avaliar as possíveis associações com estado nutricional, satisfação com o peso corporal atual, o estado de saúde autoavaliados (SRHS) e peso corporal. Método: Estudo transversal populacional realizado na cidade de Pelotas, sul do Brasil, com uma amostra de 2.097 indivíduos com idade entre 20-59 anos. BE foi avaliada através de um questionário e definido como compulsão uma ou mais vezes nos últimos três meses anteriores à entrevista. Resultados: A prevalência da BE e recorrente BE foi de 7,9% e 2,7%, respectivamente. Na análise ajustada, obesidade, SRHS justas / pobres e a insatisfação corporal permaneceu fortemente associada com a BE. Discussão: Este estudo mostrou uma elevada prevalência de CA entre adultos em Pelotas, e sua maior entre as mulheres mais jovens, gordura e aqueles que desejam pesar menos. Os resultados atuais são de caráter informativo, mas estudos longitudinais seriam necessários para demonstrar a relação causal entre esses eventos.

Objective: Adolescents with binge-eating disorder (BED) are suffering from weight teasing and, as found in adults with BED, are likely to internalize weight bias. Weight teasing by mothers accounts for psychopathology in overweight, but sources of stigmatization are largely unknown in BED. This study sought to address familial weight bias in adolescents with overweight and BED by examining adolescents’ perceived parental weight teasing and weight bias internalization in relation to their eating disorder psychopathology and maternal stigmatizing attitudes and beliefs. Method: Adolescents with overweight and BED (BED; n = 40) were compared to a socio-demographically matched group with overweight only (OW) and a normal-weight control group (NW; each n = 25). They filled out the Perception of Teasing Scale, with parents as the source of teasing, the Weight Bias Internalization Scale and the Eating Disorder Examination-Questionnaire. Their mothers filled out the Attitudes Toward and Beliefs about Obese Persons Scales. Results: Significantly higher perceived parental weight teasing and weight bias internalization were found in BED compared to OW and NW. Maternal stigmatizing attitudes and beliefs did not differ between groups and were not correlated with adolescents’ perceptions of being stigmatized. Perceived parental weight teasing predicted adolescents’ eating disorder psychopathology, however, this association was fully mediated by weight bias internalization. Discussion: These results indicate that adolescents with overweight and BED perceive weight teasing in their own families. As we found no significant association between adolescents’ perceptions of being stigmatized and maternal stigmatizing attitudes, future research should examine weight-related parent-child interaction or implicit measures of stigmatizing attitudes.
