Morbid obesity was defined by body mass index (BMI) greater than 40 or between 35-39 kg/m2 associated with comorbidity. The following variables were prospectively collected and analyzed age, sex, height, weight, BMI, toxic habits, insomnia and excessive daytime sleepiness, measured by the Epworth Sleepiness Scale. All patients underwent nocturnal respiratory polygraphy for the assessment of OSA.Results: We studied 145 patients (70% women) with a mean age of 42 years (range 19-69) and a mean BMI of 46±5.9. The prevalence of OSA was 95%. The prevalence of somnolence and insomnia in patients who suffer from OSA was 39% and 28% respectively. There was no statistically significant relationship between insomnia and somnolence (p 0.378). The association between OSA, somnolence and insomnia are shown in Table 1.View this table:Relationship between OSA, somnolencia and insomniaConclusions: The prevalence of daytime sleepiness and insomnia in patients with morbid obesity with bariatric surgery indication and OSA is high but we have not found a statistically significant relationship between both clinical entities.
