Prevalence of nocturia in Parkinson's disease patients from various ethnicities.
OBJECTIVE
One of the most common non-motor symptoms in Parkinson's disease (PD) is nocturia. This paper seeks to address the prevalence of nocturia in PD and correlate it to various factors such as gender, Hoehn and Yahr (H&Y) stage, age, and ethnicities.


METHODS
In particular, 332 PD patients were seen in a community movement disorders clinic and their charts were analyzed from 2005 to 2010. Within this population, more than one-third (34.9%) patients were diagnosed with nocturia.


RESULTS
Age, gender, and PD stage were significant predictors of nocturia in PD. With every one-year increase in age, the odds of developing nocturia in PD increases by 3.1% while an increase in H&Y stage increases the odds of nocturia in PD by 1.645 times. Also, males had greater odds of experiencing nocturia in PD. Ethnicities alone were of no significant importance. However, after performing interaction analyses, Asian and Indian males, especially, were at significantly greater risk than other ethnicities.


CONCLUSIONS
Future research is indeed required to understand why certain ethnicities are especially at risk. Clinicians must also be aware of the epidemiology of nocturia in PD to prevent and treat this debilitating symptom.
