Abstract

Objectives To test the hypothesis that subjective and objective sleep disturbances are associated with risk of incident falls in older men. Design The prospective observational MrOS Sleep Study. Setting Six academic clinical centers in the United States. Participants Community-dwelling men aged 67 and older (mean 76) (n = 3,101). Measurements Subjective sleep measurements included daytime sleepiness (Epworth Sleepiness Scale (ESS)), sleep quality (Pittsburgh Sleep Quality Index (PSQI)), and total sleep time (TST). Objective sleep measurements included actigraphic TST and sleep efficiency (an index of fragmentation) and sleep disordered breathing (measured using in-home polysomnography). Fall frequency during the subsequent year was ascertained three times per year using questionnaires. Recurrent falling was defined as having two or more falls in the subsequent year. Results In multivariable- adjusted models, participants with excessive daytime sleepiness (ESS > 10) but not poor subjective sleep quality (PSQI > 5) had greater odds of experiencing two or more falls in the subsequent year (odds ratio (OR) = 1.52 95% confidence interval (CI) = 1.14-2.03). Based on actigraphic recordings, the odds of having recurrent falls was higher for men who slept 5 hours or less (OR = 1.79, 95% CI = 1.22-2.60) than for those who slept 7 to 8 hours. Actigraphically measured sleep efficiency was also associated with greater risk of falls, as was nocturnal hypoxemia (≥10% of sleep time with arterial oxygen saturation
