Obstructive sleep apnoea syndrome in younger and older age groups - differences and similarities
open access
Abstract
Aim of the paper was the camparison of the severity and clinical features of OSA in young and elderly subjects. The study was a retrospective analysis of 561 subjects aged > 65yrs and 319 subjects aged < 35yrs who were investigated in our Sleep Laboratory between 1992-2005 due to snoring or daytime sleepiness. They all underwent full polisomnography or a limited recording. In patients with diagnosed OSA (AHI > 10) we initiated CPAP therapy.
Results: OSA was diagnosed in 383 (63,3%) older patients and in 144 (45,1%) younger patients. BMI was significantly higher in younger subjects than in older (32,2 ± 6,9 vs. 28,9 ± 5,1 kg/m2).The prevalence of OSA among women was significantly higher in older patients than in younger (26,4 vs. 5,8%). Younger patients with OSA had a significantly higher AHI(42,7 ± 32,1 vs. 32, 2 ± 18,4)and a longer duration of apneas expressed as percentage of total sleep time spent in apnea (31,6 ± 23,2 vs. 26,5 ± 17,7%). CPAP therapy was initiated in 185 older patients and 41% of them continue therapy. In younger group patients CPAP therapy was started in 51 patients and 47% of them continue therapy. The mean therapeutic pressure was significantly higher in younger patients with OSA (9,2 ± 2,2 vs. 8,2 ± 2,2 cm H2O).
Conclusions: 1/ OSA is more frequent in elderly patients ; 2/ in young patients OSA is more severe and requires higher pressures in CPAP therapy; 3/ OSA among women is four time more frequent in older patients than in younger.
