Linkage of Lower Urinary Tract Symptoms to Sleep Quality in Elderly Men with Nocturia: A Community Based Study Using Home Measured Electroencephalogram Data

Purpose: We objectively investigated the relationship between sleep quality/efficiency and factors associated with micturition using at-home electroencephalogram assessment.Materials and Methods: Participants were recruited from among those enrolled in the Fujiwara-kyo Study, a community based longitudinal evaluation that began in Nara Prefecture, Japan, in 2007. Included participants were men at least 65 years old who woke up in the middle of the night/early morning at least 3 times per week with the urge to void. We evaluated lower urinary tract symptoms using the I-PSS and subjective sleep quality using the Pittsburgh Sleep Quality Index. Uroflowmetry and 3-day frequency volume charting measurements were also obtained. Electroencephalogram recordings were obtained during sleep to evaluate objective sleep quality.Results: Final analysis included data from 47 participants. I-PSS-quality of life score and slow wave sleep time were independent predictors of good subjective sleep quality as determined by Pi...
