Sleep disordered breathing (SDB) is a considerably common sleep disorder that can be very disruptive to your sleep which in turn can affect your overall wellbeing and quality of life. EuroQol (EQ-5D) is a standardized instrument for use as a measure for health outcome. The purpose of this paper is to compare quality of life in SDB and that in healthy controls with Korean version of listed measurements. Data was collected from a total of 600 representative healthy controls and 288 SDB patients. After ruling out for snoring and controlling for age and gender, remaining 229 controls were enrolled in this study. All SDB patients completed overnight polysomnography (PSG) and divided into four subgroups (simple snoring, mild, moderate, severe) according to apnea-hypopnea index (AHI). Three patients showing normal PSG findings were excluded. We evaluated quality of life using Korean version of the EQ-5D index, EQ-visual analogue scale (EQ-VAS) and Epworth sleepiness scale (ESS). The mean age of patients and healthy controls were 46 and 42.3, respectively. The proportions of male subjects were 86.8% and 85.8%. EQ-VASs were 73.2 ¡3/4 15.7 and 81.5 ¡3/4 12.3 in patients group and healthy controls, respectively ( p < 0.005). EQ-5D index were 0.939 ¡3/4 0.094 and 0.963 ¡3/4 0.059 in patients group and healthy controls ( p < 0.001). The EQ-VASs and EQ-5D index were lower in patients group than in healthy controls. ESS scores were 11.3 ¡3/4 5.0 for patients group and 4.3 ¡3/4 3.0 for healthy controls ( p < 0.005). ESS scores were higher in patients group than in healthy controls. Patients group was classified as 42 (14.7%) simple snoring, 52 (18.3%) mild-, 77 (27%) moderate -, 114 (40%) severe sleep apnea patients. The mean ESS score of simple snoring and severe sleep apnea patients were 10.0 ¡3/4 4.0 and 12.06 ¡3/4 5.12. Statistically significant differences were found between two subgroups ( p < 0.05). Correlation analysis revealed a significantly negative linear correlation between ESS scores and EQ-VAS ( p = 0.003 r = −0.174). We founded that general quality of life in sleep apnea were poorer than that in healthy controls using Korean version of EQ-5D, ESS scores and EQ-VAS.
