Abstract
Objective: The aim of this study was to investigate the frequency of obesity in patients with various degrees of severity of OSAS, the prevalance of hypertension (HT), cardiovascular diseases (CVD) and diabetes mellitus (DM) coexisting with OSAS, and the relationship between obesity and these conditions. Material and Method: 729 subjects performed polysomnography. We retrospectively evaluated height, weight/body mass index (BMI), neck circumference (NC), polysomnographic findings: apnea/ hypopnea index (AHI), mean saturation value, minimum saturation value, maximum apnaeic period, sleep efficiency, Epworth sleepiness scale and concomitant diseases of the patients. Patients were divided into four groups: normal weight (BMI<25), overweight (25≤BMI<30), class I obesity (30≤BMI<40), class II obesity (40≤BMI). Results: While 49.3% of normal weight patients were diagnosed as primary snoring, only 15.5% of normal weight patients had a diagnosis of severe OSAS. On the other hand, 46.3% of class I obese patients and 72.7% of class II obese patients were diagnosed as severe OSAS. BMI and NC were found to influence the increase of AHI independently of age and gender (p<0.001). It was determined that 156 patients with HT (21.4%), 39 patients with CVD (5.3%) and 70 patients with DM (9.6%) had concomittant diseases. Among these diseases HT was found to be significantly related with obesity (p<0.001). In addition to AHI and age, increased BMI also influences the Epworth sleepiness scale score (p<0.001). Conclusion: Severe OSAS frequency in patients with >30 BMI was significantly high in our series. BMI and NC increase AHI independently of age and gender. Hypertension is found to be the most common concomitant disorder for both obesity and OSAS. (Tur Toraks Der 2011; 12: 105-10)
Özet
Amaç: Bu çalışmada farklı şiddetteki OSAS tanısı konulmuş olgularda obezite sıklığını ve OSAS’a eşlik eden hipertansiyon, kardiyovasküler hastalık (KVH) ve diyabetes mellitus (DM) un prevalansını ve obezite ilişkisini araştırmak amaçlanmıştır. Gereç ve Yöntem: Retrospektif olarak laboratuarımızda OSAS ön tanısı ile polisomnografi yapılmış 729 olgunun boy, kilo, vücut kitle indeksi (VKİ), boyun çevresi (BÇ), polisomnografik bulgular (apne hipopne indeksi (AHİ), ortalama satürasyon, en düşük satürasyon, en uzun apne süresi, uyku etkinliği), Epworth uykululuk skalası ve eşlik eden hastalıklar değerlendirilmiştir. Obezite gruplandırması normal VKİ 30 olan olgularda ağır OSAS görülme oranı oldukça yüksektir. VKİ ve BÇ diğer faktörlerden bağımsız olarak AHİ’i artırmaktadır. Hipertansiyon hem obezitede hem de OSAS’da en sık eşlik eden hastalık olarak bulunmuştur. (Tur Toraks Der 2011; 12: 105-10)
