Correlation Analysis between SF36 and Polysomnographic Measures in Patients with OSAS / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Despite the trend in the medical field to understand the effect of diseases on the quality of life, such a study regarding sleep apnea has not been prevailing in Korea. This study analyzed the result of a Medical Outcome Study Short Form-36 (SF-36), which is widely used to evaluate the effect of sleep apnea on patient's medical condition. SUBJECTS AND METHOD: This study included 131 patients of over 18 years of age and who participated in the SF-36 survey and finished the polysomnography study. The relationship between parameters was conducted with Spearman, and the comparison with the independent variables was done by running a paired t-test. RESULTS: AHI was on average 30.9+/-23.5 and BMI was on average 26+/-3.9 kg/m. Except body pain, all values which derived from the statistics of eight categories of SF-36 from the patients was significantly lower than those of the healthy control. In the comparable analysis of polysomnography and SF-36, AHI, the total sleep time, and the sleep efficacy (%) had significant correlation, but correlation coefficient was low (r<3.0). CONCLUSION: It is recommended that the quality of life of OSAS patients should be evaluated beside PSG in order to find out the degree of seriousness of OSAS and result of treatment.
