    Objective: The aim of this study was to examine the hypothesis that non-purge-related binge-eating in obesity is maintained by a 'trade-off' in which a highly aversive emotional state is exchanged for a less aversive state. Method: Ninety-eight obese binge-eaters meeting the DSM-IV criteria for binge-eating disorder [1] were contrasted with 65 non-binge-eating controls on their perceived distress associated with negative mood states usually experienced before and after binges. Results: Binge-eaters reported significantly greater distress and lower tolerance of negative mood compared to controls. Furthermore, when compared with controls, binge-eaters reported that emotions typically reported before binges (e.g. anger) were more aversive than those reported after (e.g. guilt). Conclusions: These results were interpreted as supporting the 'trade-off' theory and have implications for the treatment of binge-eating disorder

    BACKGROUND: A few studies have shown high rates of eating disorders and psychiatric morbidity in patients with type 2 diabetes mellitus. OBJECTIVE: disturbed eating behavior and psychiatric comorbidity in a sample of T2DM patients. METHODS: Seventy type 2 diabetes mellitus patients between 40 and 65 years of age (mean, 52.9 ± 6.8) from a diabetes outpatient clinic were sequentially evaluated. The Structured Clinical Interview for DSM-IV, Binge Eating Scale and Beck Depression Inventory were used to assess eating disorders and other psychiatric comorbidity. In addition to the descriptive analysis of the data, we compared groups divided based on the presence of obesity (evaluated by the body mass index) or an eating disorder. RESULTS: Twenty percent of the sample displayed an eating disorder. Binge eating disorder was the predominant eating disorder diagnosis (10%). Overall, the group of obese patients with type 2 diabetes mellitus presented rates of psychiatric comorbidity comparable to those seen in their nonobese counterparts. However, the presence of an eating disorder was associated with a significant increase in the frequency of anxiety disorders (57.1% x 28.6%; p = 0.044). CONCLUSIONS: In our study sample, the occurrence of eating disorders was increased compared to rates observed in the general population, with the predominance of binge eating disorder. The presence of an eating disorder in type 2 diabetes mellitus patients was associated with higher rates of anxiety disorders.<br>INTRODUÇÃO: Alguns estudos têm demonstrado uma freqüência elevada de transtornos alimentares (TA) e morbidade psiquiátrica em pacientes com diabetes mellitus do tipo 2 (DM2). OBJETIVOS: Investigar a presença de alterações do comportamento alimentar e comorbidade psiquiátrica em uma amostra de pacientes com diabetes mellitus do tipo 2. MÉTODOS: Setenta pacientes com diabetes mellitus do tipo 2, com idade entre 40 e 65 anos (média de 52,9 ± 6,8), em tratamento regular em um serviço de diabetes, foram seqüencialmente avaliados. Para avaliação da morbidade psiquiátrica foi utilizado o Structured Clinical Interview for DSM-IV, além da Escala de Compulsão Alimentar Periódica e o Inventário Beck de Depressão. Além da análise descritiva dos dados, foi realizada uma avaliação comparativa da amostra dividida em grupos, com base na presença de obesidade (avaliada através do índice de massa corporal) e de transtornos do comportamento alimentar. RESULTADOS: Foi encontrada uma prevalência geral de 20% de transtornos alimentares, sendo o transtorno da compulsão alimentar periódica (TCAP) o de maior ocorrência na nossa amostra (10%). O grupo de obesos com diabetes mellitus do tipo 2 não apresentou aumento de comorbidade psiquiátrica quando comparado com os pacientes diabéticos não-obesos. Entretanto, quando comparamos o grupo de pacientes com alterações do comportamento alimentar com aqueles sem transtornos alimentares, a presença de um transtorno alimentar esteve associada a um aumento na freqüência de transtornos de ansiedade (57,1% vs. 28,6%; p = 0,044). CONCLUSÕES: Em nosso estudo, a ocorrência de transtornos alimentares esteve aumentada em relação às taxas observadas na população geral, com o predomínio do transtorno da compulsão alimentar periódica. A presença de um transtorno alimentar em pacientes com diabetes mellitus do tipo 2 esteve associada a uma maior ocorrência de transtornos de ansiedade
