Clinical and Polysomnographic Differences in Elderly Obstructive Sleep Apnea Patients

Objectives: Although sleep-related complaints are common in the community, knowledge about clinical and polysomnographic differences in elderly patients with obstructive sleep apnea (OSA) is limited.The aim of this study was to compare the clinical and polysomnographic characteristics of OSA patients who were older than 65 years and those younger than 65 years. Materials and Methods:We retrospectively reviewed the polysomnography data of 216 (100 F/116 M) OSA patients who underwent polysomnography between 2011 and 2014.The patients were divided into two groups: <65 years (Group 1), ≥65 years (Group 2).We evaluated symptoms, comorbidities, and polysomnographic findings of the two groups of patients.Results: There were 185 patients (82 F/103 M) in Group 1 and 31 patients (18 F/13 M) in Group 2. There were no differences in gender distribution, OSA-related symptom frequency and Epworth sleepiness scale rates between two groups.The comorbidities, including hypertension (p=0.05),atherosclerotic heart disease (p=0.005),diabetes mellitus (p=0.002),depression (p=0.007), and COPD (p=0.035), were more frequent in Group 2. Although statistically non-significant, TST, sleep efficiency and average oxygen saturation at sleep were lower (p=0.129,p=0.127, p=0.063, respectively) whereas the AHI and the arousal index were higher (p=0.699,p=0.545, respectively) in Group 2. There was no difference between the two groups in terms of mean apnea duration.Conclusion: OSA patients had similar symptoms and polysomnographic findings independent from age.OSA should not be ignored in elderly patients when comorbidities are considered.
