Summary
Nocturia, or frequent nighttime urination, is common in older adults. This study found no link between nocturia and common conditions like hypertension or diabetes, but a strong association with incontinence and daytime urgency.
Area of Science:
- Gerontology
- Urology
- Epidemiology
Background:
- Nocturia is a prevalent condition in elderly populations, impacting quality of life.
- Understanding the associations between nocturia and other health conditions is crucial for effective management.
Purpose of the Study:
- To investigate the relationship between nocturia and specific co-existing diseases and medications in community-dwelling older adults.
- To identify factors associated with increased nocturnal voids in the elderly population.
Main Methods:
- A validated questionnaire was mailed to residents aged 65+ in Tierp, Sweden.
- Descriptive statistics and logistic regression were used to analyze data, controlling for age and gender.
- Respondents were categorized into non-nocturics, intermediate, and nocturics based on reported nighttime voids.
Main Results:
- The prevalence of nocturia increased with age, with men reporting it more frequently than women.
- No significant correlation was found between nocturia and hypertension, angina pectoris, diabetes mellitus, or their treatments.
- Nocturia showed strong statistical correlations with incontinence, daytime urge, and nocturnal thirst, and was negatively correlated with good sleep and perceived health.
Conclusions:
- Nocturia in the elderly is not significantly correlated with treated hypertension, angina pectoris, congestive heart failure, or diabetes mellitus.
- Urinary incontinence and daytime urgency are strongly associated with increased nocturnal voids in older adults.
