Presby-sleep: analysis of some sleep parameters in elderly patients

Analyze reports and reports of nocturnal polysomnography with oximetry and correlate respiratory disorders with other variables related to sleep, in a long-lived population.

A retrospective, cross-sectional study was carried out, based on the analysis of reports and reports of nocturnal polysomnography with oximetry, performed on outpatients aged 80 or older, referred for diagnosis of various sleep disorders.

N= 245. The average age was 83 years (80-94). We divided the data according to sex into male (n=123), female (n=122) and according to age from 80 to 84 years (n=176) and 85 or more years of age (n=69). Moderate obstructive sleep apneas were greater in men (p=0.04) and oxygen desaturation was greater in women (p=0.00) who also had greater sleep onset latency

The analysis of presby-sleep in the elderly population showed statistically significant data, when differentiating by age, given that the oldest people had the longest REM phase onset latency and the lowest percentage of deep slow sleep. When differentiated by gender, women took longer to fall asleep. The most prevalent diagnoses were obstructive sleep apnea followed by periodic leg movements. The rate of severe respiratory events was correlated with prolonged REM onset latency and a lower percentage of both superficial and deep sleep. Showing the objective changes that occur in sleep in the elderly can help consider improving the diagnostic and/or therapeutic approach to sleep disorders in the elderly population.
