2Dışkapı Yıldırım Beyazıt Eğitim ve Araştırma Hastanesi Göğüs Hastalıkları Kliniği ANKARA Introduction: This study aimed to assess the factors associated with the coexistence of COPD and OSA symptoms.
Materials and Method: An interviewer-administered questionnaire and pulmonary function testing was applied to 2199 (female: 52.2%) subjects, admitted to the outpatient clinics of chest medicine in a Training and Research Hospital in Ankara. COPD was defined as the FEV1/FVC of <0.7. OSA symptoms was defined as the presence of all three symptoms snoring, witnessed apnea and daytime sleepiness.
Results: Prevalence of COPD, OSA symptoms and coexistence of COPD and OSA symptoms were 29.4, 4.0, 2.2 in men and 11.6, 5.0, 0.5 in women, respectively. There was a strong association between age, male gender, ever exposure to fume, family atopy, lower education status and coexistence of COPD and OSA symptoms after the adjustment for age, gender, BMI and pack-year of smoking. Among males, FEV1% was lower in the COPD coexistence group than COPD only group (beta; 95%CI: -7.6; -0.4 to -14.8) after the adjustment for pack year of smoking.
Conclusion: Atopic status and fume exposure could be risk factors for OSA in COPD patients. This association should be evaluated in further, follow-up studies with the confirmation of OSA diagnosis.
