lntroduction: there is a clear relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and overweight; both, in their turn, are associated with increased cardiovascular risk. In Colombia, there is scarce data about the frequency of OSAHS and its association with these factors. In this article, we describe the prevalence of obesity and metabolic syndrome in patients with OSAHS at Hospital Universitario San Ignacio in Bogotá.
Methods: we describe the frequency of obesity (body mass index greater than 30) in patients with OSA, abdominal perimeter, total cholesterol values, HDL, triglycerides, LDL, fasting blood glucose, and TSH; as well as the differences between patients with and without OSAHS and those with and without metabolic syndrome.
Results: from the total number of subjects, 215 were diagnosed with OSA (66%), 69 did not have the syndrome (21.4%), and 37 had an invalid polysomnogram. A high prevalence of metabolic syndrome was found in the subgroup of patients that was analyzed. Most of the patients with metabolíc syndrome had OSA, which was not statistically significant (p=O, 155), possibly dueto the fact that it was a small sample of the total poputation. No correlation was found between the Epworth sleepiness scale and the severity of OSA according to the apnea-hypopnea index (r=O, 13).
Conclusions: in accordance with the literature, this study found a high prevalence of obesity and OSA in the population under study. There was a high rate of coexistence of metabolic syndrome, OSA, and high blood pressure, which confirms the fact that these patients form a group whose cardiovascular risk is high, and therefore require earty intervention.
