A cross-sectional study was conducted among patients that underwent bariatric surgery (laparoscopic sleeve gastrectomy). Sleep quality was assessed using the Pittsburgh sleep quality index (PSQI) scale preoperatively and at the 6th postoperative month. Survey data were recorded and PSQI scores were calculated. A PSQI global score above 5 indicates poor sleep quality. The participants were divided into two groups good sleep quality and poor sleep quality. Descriptive statistics and Spearman correlations were applied. Logistic regression analysis was performed to predict sleep quality.
Obesity, caused by caloric intake over output, has become a global health problem. The relationship between sleep and obesity is widely discussed in the literature. Little is known regarding the compliance of sleep quality and patients' weight loss. This study aimed to review how sleep quality is affected by bariatric surgery, examine whether compliance with sleep quality can be predicted after bariatric surgery, and assess its correlation with excess weight loss.
