Can nocturia hasten death?
Nocturia (voids arising from sleep) is a ubiquitous phenomenon reflecting many diverse conditions. In this patients, the sleeping can be interrupted several times in a night. This patients can have daytime sleepiness, decreased concentration and potential riscky accidents.
The researchers analyzed data from 7343 mostly white participants (aged 50-75) in the REDUCE trial (Reduction by Dutasteride of Prostate Cancer Events). Men who reported 3 or more voids per night had a 72% greater risk for all-cause mortality.
When disturbed sleep, measured by the Medical Outcomes Study questionnaire, was finally added to the model, the excess death risk fell to 43%.
The interruption of sleep by nocturia may have long-term impact on health and may warrant targeted intervention.
Nocturia can lead to poor sleep and vice versa. The researchers also acknowledged that falls may play a role, since falling has been linked to both nocturia and death.
