PURPOSE: Sleep related disorders are mostly seen in the elder population. Sleep apnea increases with the age. We aimed to investigate the sleep architecture in older people with obstructive sleep apnea (OSA) and the reasons of higher apnea-hypopnea indices (AHI) as reported in literatures.
METHODS: Patients refered to our sleep center with snoring, witnessed apnea and/or daytime sleepiness between November 2010-December 2011 were taken and the polisomnograpy reports were analysed retrospectively. Patients with sleep efficiency less than 40% and younger than 25 years old were excluded.
RESULTS: 343 patients (220 patients < 65 years’ old; mean 50.2±9.3 years’old , 123 patients>65 years’old; mean 69.7±4.7 years’old) were accepted. BMIs were similar in both groups. Sleep efficiency, deep sleep percentage were less,while light sleep and AHI were higher in older group. Total number of apneas and hypopneas were similar. Mean apnea duration and PLMI were more and respiratory arousals were less in the older group.
CONCLUSIONS: Older people reach the similar total number of apnea-hypopnea events in a less sleep time than younger. As a result, apnea-hypopnea indexes are found to be higher in the older group. The decay in the respiratory arousal system may be the cause of the increase in the mean apnea duration in the older patients. Especially sleep apneic patients older than 65 years’old should be carefully examined for periodic leg movement disease, low ferritine levels and comorbidities.
CLINICAL IMPLICATIONS: Sleep apneic patients older than 65 years’old should be examined carefully. Co-morbidities of those older patients may explain the higher apnea-hypopnea indices.
