AimsNocturia, due to nocturnal polyuria and other conditions associated with nocturnal voiding, affects sleep quality and daytime quality of life (QOL). We aimed to investigate the relationship among nocturia, sleep quality, and daytime QOL in a young Japanese population.MethodsThis epidemiological study analyzed data from a retrospective data set containing sleep data from wearable devices worn by 9446 Japanese users and a prospective data set containing answers to a 10-item questionnaire completed by a subset of 605 users in the retrospective dataset. We recorded the first uninterrupted sleep period (FUSP), total sleep time (TST), number of nocturnal voids, sleep quality, daytime QOL, bothering nocturnal voids, and early wake-ups in the morning.ResultsThe subjects were 18-65 years old. The mean TST was 6.7 ± 0.9 h, and the mean number of wake-ups was 2.11 ± 1.1. FUSP and TST decreased (from 334 ± 114 to 173 ± 74 min and 5.9 ± 1.0 to 5.5 ± 1.0 h, respectively) with an increasing number of nocturnal voids, and the change was statistically significant. Logistic regression analysis showed a statistically significant relationship between nocturia and FUSP and the number of wake-ups.ConclusionNocturia has close relationships with FUSP and the number of wake-ups and can result in decreased daytime QOL in young Japanese people.© 2020 Wiley Periodicals LLC.
