Weight and height data were collected for body mass index (BMI) calculation, using the night feeding questionnaires, the Pittsburgh Sleep Quality Index (PSQI), and an adapted questionnaire about the practice of physical activity (PA). The data were analyzed in Statistical Package for the Social Sciences, v. 24.0 (statistical significance p < 0.05). The research was approved by the Research Ethics Committee (No. 5.180.990).
Results:
A total of 125 adults were evaluated in the preoperative stage of bariatric surgery, with an average BMI 46.2 kg/m2 (±7.4), 51.2% were physically active, with an average practice of PA of 219 (±128.8) min. It was observed that 14.4% of participants met criteria for suggestive night eating syndrome (NES) behavior and 72% of participants had poor sleep quality. The PSQI score was a predictor of NES symptoms, regardless of BMI and practice of PA (B = 0.788, 95% confidence interval = 0.548–1.028, p < 0.001).
Level of Evidence:
Level III, well-designed cohort or case–control analytic studies.
Conclusion:
Sleep quality was found to be a predictor of NES suggestive behavior.
