Does poor sleep quality and excessive daytime sleepiness influence fear of falling among older adults? A cross-sectional study

Abstract

Poor sleep is a risk factor for falling among older adults. This study aimed to investigate whether poor sleep quality and excessive daytime sleepiness in older people was associated with fear of falling. Participants aged 60 years or older were interviewed, with those who did not have preserved cognitive skills being excluded. Data on age, gender, body mass index, alcohol consumption, mental status, depression, excessive daytime sleepiness, sleep quality, comorbidities and fear of falling were collected. Univariate and multivariate linear regression were conducted. The logistic regression assessed the association between daytime sleepiness and fear of falling. The odds of an older adult being afraid of falling was 3 times higher among those with excessive daytime sleepiness, in comparison to those with no excessive daytime sleepiness. The higher the daytime sleepiness, the greater the fear of falling. Health professionals should be aware of older patients’ sleepiness because it can increase fear of falling and influence their treatment.
