Abstract

Background: Among the eating disorders, the binge eating disorder is a factor which exacerbates the obesity, because it generates changes in life quality and accentuates the comorbidities related to the individuals eating behavior. Thus, the aim of this study was to estimate the prevalence of binge eating disorder among patients with overweight in outpatient care and to evaluate its associated factors. Methods: The study was transversal made in 272 patients at the clinics in University Hospital of Dourados-MS. The collected data were the sociodemographic, behavioral, anthropometric and clinic data and the food consumption. The statistical tests for the categorical data analyses were the Chi-square test or Fisher’s test and for the continuous data, the t-student or Mann-Whitneytest. The variables which had shown value of p≤0,05 in bivariate analyses were selected for the multivariate analyses performed by the Logistic Regression. It had been adopted the significance level of p≤0,05. Results: Among the evaluated, 32,7% had shown binge eating disorder, which is more prevalent among women (77,6%) and adults (82%; p=0,007).Concerning the body satisfaction, 76,4% of the individuals with binge was dissatisfied. Among patients with binge, 57,3% referred to have followed some diet. In the comorbidities evaluation, 53,7% of patients were hypertensives, 38,6% are dyslipidemics and 21,6% diabetics. In the food frequency, it was observed that the intake of sugary drinks was bigger in the group with binge (p=0,05). Conclusion: It was concluded that the prevalence of binge eating disorder in this population is high, and that the patients’ profile which are compulsive eaters is composed, in its majority, by women and adults, suggesting that these groups suffer higher cultural and social pressure related to overweight. Another factor that stands out is dissatisfaction with the body image, which can be a relevant trigger for binge eating. Moreover, the sedentary lifestyle and the unappropriated food ingestion are factors that certainly collaborate on the outbreak of the diseases observed in these groups. Therefore, this research can be used as an important data source for the elaboration and guidance of public policies for the prevention and treatment of obesity in susceptible groups.
