Abstract:
PURPOSE: This study aimed to evaluate the correlation between associating factors of moderate to severe asthma with obstructive sleep apnea (OSA). MATERIALS AND METHODS: One hundred and sixty-seven patients who visited the pulmonary and sleep clinic in Severance Hospital presenting with symptoms of sleep-disordered breathing were evaluated. All subjects were screened with ApneaLink. Thirty-two subjects with a high likelihood of having OSA were assessed with full polysomnography (PSG). RESULTS: The mean age was 58.8+/-12.0 years and 58.7% of subjects were male. The mean ApneaLink apnea-hypopnea index (AHI) was 12.7+/-13.0/hr. The mean ApneaLink AHI for the 32 selected high risk patients of OSA was 22.3+/-13.2/hr, which was lower than the sleep laboratory-based PSG AHI of 39.1+/-20.5/hr. When OSA was defined at an ApneaLink AHI > or =5/hr, the positive correlating factors for OSA were age, male gender, and moderate to severe asthma. CONCLUSION: Moderate to severe asthma showed strong correlation with OSA when defined at an ApneaLink AHI > or =5/hr.
