Sintomas de Síndrome do comer noturno e qualidade do sono em candidatos à cirurgia bariátrica

Abstract

Introduction: Severe obesity predisposes to disordered eating behaviors, such as night eating syndrome (NES). The aim of this study was to analyze whether sleep quality is a predictive factor of NES behavior in candidates for bariatric surgery (BS) and whether this relationship can be influenced by the weight and practice of physical activity (PA). Method: A nonprobabilistic sampling was conducted with adults in the preoperative period of bariatric surgery. Sociodemographic and anthropometric data (weight and height) were collected, and the Night Eating Questionnaire (NEQ) and Pittsburgh Sleep Quality Index (PSQI) were applied. Statistical analysis was performed using SPSS 24.0 (statistical significance p<0.05), employing normality tests, Spearman correlations, and linear regression, considering the NEQ score as the dependent variable. The study evaluated associations between sleep quality, BMI, and physical activity with night eating behaviors. The research was approved by the Research Ethics Committee (No. 5.180.990). Results: 125 adults were evaluated in the preoperative BS, with an average BMI 46.2kg/m² (± 7.4), 51.2% were physically active, with average PA practice of 219 (± 128, 8) minutes. It was observed that 14.4% of participants met criteria for suggestive NES behavior and 72% of participants had poor sleep quality. The PSQI score was a predictor of SCN symptoms, regardless of BMI and PA practice (β = 0.506; IC = 0.548-1.028, p <0.001). Conclusion: Sleep quality was predicting NES suggestive behavior.
