Abstract

Objective: We aimed to determine the association between psychomotor vigilance task (PVT) performance and sleep-related factors including sleep duration, daytime sleepiness, poor sleep quality, insomnia, and habitual snoring in a population-based sample. Methods: This was a cross-sectional analysis from the ongoing prospective cohort study, the Korean Genome and Epidemiology Study. We measured PVT performance and documented demographics, sleep-related factors, life style, and medical conditions in community dwelling adults (N=2499; mean age 57.1±7.3; male 1259). Associations between PVT parameters and sleep-related factors were tested, adjusting for age, gender, smoking, alcohol use, education, body mass index, hypertension, diabetes, depression, and the interval between mid-sleep time and PVT test. Results: High Epworth Sleepiness Scale (ESS, ≥8) was associated with slower mean reciprocal response speed (mean RRT) (3.69±0.02 vs. 3.77±0.01, p<0.001), higher probability for increased lapses (≥4) (OR 1.48, CI 1.12-1.88, p=0.001), and more negative RRT slope (-0.036±0.002 vs. -0.030±0.001, p=0.02). Older age, female gender, low education level, depressive mood, and the interval between mid-sleep and PVT test were also associated with poor performance. Sleep duration, habitual snoring, insomnia, or poor sleep quality (the Pittsburgh Sleep Quality Index score>5) was not related to PVT parameters. Conclusions: At the population level, our results revealed important modifiers of PVT performance, which included subjective reports of daytime sleepiness.
