FREQUENCY OF SLEEP DISORDERS IN PATIENTS AGED 65 YEARS OR OLDER
INTRODUCTION: The elderly may present changes in sleep, such as decreased total sleep time to less than 6 to 7.5 hours, more superficial sleep, and may predispose to the emergence of nocturnal awakenings, sleep fragmentation and afternoon nap.
OBJECTIVE: To evaluate the frequency of sleep disorders in patients aged 65 years or older.
METHOD: This is a cross-sectional study. Study sample: Individuals who sought a sleep laboratory in Salvador (Ba) were evaluated. Project approved by the research ethics committee. Inclusion criteria: Patients who answered questionnaires with information about the characteristics of sleep which were applied between 2014 and October/2018 in individuals aged 65 years or older who sought a sleep laboratory in Salvador (Ba). Exclusion criteria: Medical records with incomplete data.
RESULTS: This sample consisted of 115 patients, mean age = 72.5±6.3 years, female = 53%, BMI = 27.7±6.9 kg/m², Epworth Scale = 8.5 (6-15), bedtime = 22:15±1:43 h, wake-up time = 5:51±1:31 h, total sleep time = 7:30±1:48 h. The most frequent sleep disorders were: snoring (89.6%), insomnia (47.8%), leg movements during sleep (46.1%) and assisted apnea (44.3%). Women presented greater difficulty to sleep when compared to men (62.3% vs. 31.5%; p<0.001), as it occurred in relation to body pain (67.2% vs. 40.7%; p=0.004), respectively. Men presented a higher frequency of excessive daytime sleepiness than women (46.3% vs. 16.4%; p<0.001), respectively, and a higher frequency of sleep talking (24.1% vs. 6.6%; p<0.016).
CONCLUSION: When evaluating patients aged 65 years or older, at least 89.6% had some sleep disorder.
