## Brief Summary

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.

## Detailed Description

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.

## Eligibility

```
Inclusion Criteria:

Patients who underwent LSG for morbid obesity after being considered suitable for bariatric surgery by multidisciplinary evaluation were included in this study. Patients with aged 18-65 years, BMI \> 40 and BMI \> 35 and comorbid disease were included.

Exclusion Criteria:

Patients treated for sleep disorders have been excluded.

## Arms

- **bariatric surgery** — 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.

## Interventions

- **Pittsburgh sleep quality index (PSQI) scale** (OTHER) — Pittsburgh Sleep Quality Index (PSQI) (6), a self-report questionnaire comprising seven component scores (subjective sleep quality, sleep latency, duration of sleep, sleep efficiency habits, sleep disturbances, use of sleeping medication, and daytime dysfunction), was used to evaluate sleep quality over the last month.

## Primary Outcomes

- **good sleep quality** _(time frame: 6 months)_ — A PSQI global score above 5 indicates poor sleep quality.
- **poor sleep quality** _(time frame: 6 months)_ — A PSQI global score above 5 indicates poor sleep quality.
