Amaç: Bu çalışmada Epworth uykululuk skalası EUS sonuçlarının uykuda solunum bozukluğu USB olan hastalardaki polisomnografi PSG bulguları ile uyumu araştırıldı.Hastalar ve Yöntemler: Çalışmaya horlama, apne, tanıklı apne ve gün içi uykululuk yakınması ile başvuran toplam 109 hasta 68 erkek, 41 kadın; ort. yaş 48.6 yıl; dağılım 20-77 yıl dahil edildi. Yaş, vücut kütle indeksi VKİ ve EUS ve PSG bulguları arasındaki ilişki araştırıldı.Bulgular: Yaş ile apne hipopne indeksi AHİ arasında pozitif yönde istatistiksel olarak anlamlı bir ilişki saptandı p

Objectives: This study aims to investigate the consistency of Epworth sleepiness scale ESS results and polysomnography PSG findings in the patients with sleep-disordered breathing SDB . Patients and Methods: A total of 109 patients 68 males, 41 females; mean age 48.6 years; range 20 to 77 years who were admitted with the complaints of apnea, witnessed apnea and daytime sleepiness were included. The correlation among age, body mass index BMI , and ESS and PSG findings were assessed. Results: There was a positive and statistically significant correlation between the age and apnea-hypopnea index AHI p<0.01 . We observed that AHI figures increased with increasing age. There was also a positive and statistically significant correlation between the BMI and AHI p<0.05 . We found that AHI increased in parallel with BMI increase. There was, no statistically significant correlation among the AHI results based on the ESS assessment, the percentage of sleep under 90% of saturation, and the Arousal index AI . Conclusion: The responses to the questions in the ESS may vary from individual to individual, depending on the sociocultural and economic status. We believe, therefore, that a new Turkey-based questionnaire considering the lifestyle of our population would offer more useful information about sleep disordered breathing.
