Introdução: Sabe-se que a ingestão alimentar compulsiva (IAC) é mais frequente em indivíduos com excesso de peso que procuram tratamento para a redução ponderal e que está associada a dieta, contudo os dados disponíveis são discrepantes sobre a prevalência da IAC nesta população bem como sobre o tipo de relação deste comportamento com as dietas e com a restrição alimentar cognitiva (RAC). O objetivo deste estudo foi estimar a frequência de IAC em adultos com excesso de peso que procuram tratamento para a perda de peso e analisar a relação da IAC com os dados antropométricos, o número de dietas realizadas e o grau de RAC. Metodologia: Estudo observacional analítico transversal com uma amostra de 155 participantes com excesso de peso que estavam a iniciar um programa de perda de peso. A recolha de dados foi realizada na primeira consulta de nutrição e através da entrega de questionários: sobre as dietas realizadas, do Binge Eating Scale (BES) para avaliação da IAC e do Three-Factor Eating Questionnaire-R21 (TFEQ-R21) subescala da restrição alimentar cognitiva para avaliar o grau da RAC. Resultados: A amostra, na sua maioria do género feminino (94,2%), apresentava uma idade média de 47 anos, índice de massa corporal médio de 31,1Kg/m2 e massa gorda média de 43,5%. A frequência estimada de IAC foi de 29%. Encontrou-se uma associação entre a IAC e o género feminino. A percentagem de massa gorda, o número de dietas realizadas e a expetativa de perda de peso verificaram-se estar positivamente associados à pontuação final do BES, enquanto que o grau de RAC e a idade de início de dieta encontraram-se negativamente associados à pontuação final do BES. Da amostra com IAC, 71,1% iniciou este comportamento previamente à primeira dieta realizada. Conclusão: A ingestão alimentar compulsiva é comum em adultos com excesso de peso que procuram tratamento para perda de peso. Conclui-se que os profissionais de saúde devem estar alerta e realizar um rastreio de perturbação alimentar em indivíduos com excesso de peso que pretendem emagrecer, principalmente nos com maior historial de dietas realizadas. Estudos prospetivos e mais alargados são necessários para melhor avaliar e compreender as relações entre o excesso de peso, IAC e realização de dietas.
Introduction: It is known that binge eating (BE) is more frequent in overweight individuals who seek treatment for weight loss and that it is associated with diet, however the available data shows discrepancy about the BE prevalence in this population as well as the relationship of this behavior with diets and with cognitive restraint (CR). The aim of this study was to estimate the frequency of BE in overweight adults seeking treatment for weight loss and to analyze the relationship of BE with anthropometric data, the number of diets performed and the degree of CR. Methods: A cross-sectional observational study with a sample of 155 overweight participants who were starting a weight loss program. Data collection was carried out in the first nutrition consultation and through the delivery of questionnaires: about previous diets, the Binge Eating Scale (BES) for the evaluation of BE and the Three-Factor Eating Questionnaire-R21 (TFEQ-R21) subscale of cognitive restraint to assess the degree of CR. Results: The sample, mostly female (94.2%), had an average age of 47 years, an average body mass index of 31.1 and an average fat mass of 43.5%. The estimated frequency of BE was 29%. An association was found between BE and the female gender. The percentage of body fat, the number of diets performed and the expectation of weight loss were found to be positively associated with BES total score, while the degree of CR and the age at the beginning of the diet were negatively associated with BES score. From the sample with BE, 71,1% started this behavior before the first diet. Conclusion: Binge eating is common in overweight adults seeking treatment for weight loss. It was concluded that health professionals should be alert and perfom a eating disorders screening in overweight individuals who intend to lose weight, especially in those with a greater history of diets. Prospective and more extensive studies are needed to better assess and understand the relationships between overweight, BE and diets.
