Purpose:
Obesity is a major risk factor for obstructive sleep apnea (OSA), associated with conditions like type 2 diabetes, hypertension, stroke, cancer, and premature death. OSA involves sleep-breathing interruptions, with over 60% of obese individuals diagnosed through polysomnography. This study explores sleep issues in individuals considering bariatric surgery.
Materials And Methods:
We retrospectively analyzed sleep study records and questionnaires of 137 obese patients undergoing metabolic surgery at Kosin University Gospel Hospital between January 1, 2019, and September 30, 2022. Statistical tests, including Student's t-test and logistic regression, assessed subjective and objective characteristics.
Results:
Most subjects, predominantly female with comorbidities, exhibited poor sleep quality. Positive correlations between polysomnography and subjective evaluation indicated poor results. Logistic regression revealed increased OSA likelihood with higher Apnea-Hypopnea Index, with associations to sex, age, and body mass index (BMI).
Conclusion:
Regardless of BMI, most patients with a BMI ≥30 kg/m2 undergoing bariatric surgery were diagnosed with OSA, experiencing poor subjective and objective sleep quality. Correlations between subjective and objective evaluations were significant, with sex, advanced age, and high BMI identified as significant OSA risk factors.
