BACKGROUND AND OBJECTIVES: The prevalence of obstructive sleep apnea (OSA) and metabolic syndrome (MS) is increasing and those have been recognized as potential risk factors for cardiovascular disease in adults. The aim of this study is to investigate the association between obstructive sleep apnea syndrome and metabolic syndrome. MATERIALS AND METHODS: We enrolled 127 adults who were evaluated as having OSA. Each subject underwent overnight polysomnography to identify OSA based on the apnea-hypopnea index (AHI); OSA was diagnosed when AHI≥5, and subjects with AHI<5 were classified as the control group. MS was defined according to the Adult Treatment Panel (ATP) III criteria. RESULTS: Among 127 participants, 105 subjects were diagnosed with OSA. The mean age and smoker percentage showed differences between the OSA and control group. The prevalence of MS was significantly higher in the OSA group compared to the control group. As the severity of OSA increases, the prevalence of MS also increase. CONCLUSIONS: The MS is significantly related to the OSA in adults. Therefore, we suggest that patient with OSA should be screened to identify the presence of MS.
