AUA 2018: Prevalence of Nocturia in the Geriatric Populations

San Francisco, CA (UroToday.com) Nocturia is a common complaint in the geriatric population, but its’ true prevalence is unknown. About 28 million of US adults wake up to void two or more times per night, but it is estimated that even more people suffer from the condition for years before deciding to seek medical help. Nocturia is linked to increased mortality, high risk for falls and depression, decrease in quality of life due to sleep deprivation, and decreased work productivity. The elderly population is particularly vulnerable due to the existing comorbidities.

Michael Daugherty, MD and colleagues analyzed data from the National Health and Nutrition Survey (NHANES). They looked into subject responses of how many times they usually urinate at night from 2009 – 2014. 17,547 adult participants were enrolled into the NHANES cohort with 23,2% of people ages 65 and older.  Data analysis showed confirmed that nocturia increases with age, and there is no significant difference between genders. According to the presenter, 82% of elderly adults (65 and older) report nocturic episodes and 44% suffer from severe nocturia.

Researchers looked into risk factors that could be associated with nocturia by gender. Univariate analysis revealed that disease is associated with age, race, and such comorbidities as major depression, arthritis, urinary incontinence, and overall poor self health (Table 1). 
Nocturia in the Geriatric Populations1

Nocturia was reported in 83.5% of male participants. Increased rates were associated with age of 80 and older, major depression, urge incontinence, and alpha-blockers. Higher income was linked to the lower risk of disease development.

Female cohort showed similar findings. While higher income decreased rates of nocturia, race (Black and Mexican Americans), BMI of 30 and over, poor health, urge incontinence, hysterectomy, and anticholinergic were linked to higher risk for occurrence (Table 2). 

Nocturia in the Geriatric Populations2

Study results can be limited by subject responses because people could underreport the number of nocturic voids. Therefore, it is even more important to ask a question about nighttime voiding in healthcare practices.
