Nocturnal polyuria in community-dwelling women.
OBJECTIVE
To determine the age prevalence of nocturnal polyuria among older women in the community, and to investigate the relationship between nocturnal polyuria and nocturia.


METHODS
In all, 1183 women aged > or = 50 years, who were registered with a family doctor practice and who had taken part in a prevalence study, were sent brief questionnaires and a frequency/volume chart (FVC) to complete.


RESULTS
There were 227 FVCs with adequate data and 264 completed questionnaires available for analysis. The prevalence of nocturnal polyuria increased disproportionately with age. There was no clear relationship between nocturia or nocturnal polyuria and daytime frequency, nor was there a clear relationship between diuretic use and nocturnal polyuria.


CONCLUSIONS
Nocturnal polyuria is common among women in the community and not obviously related to daytime frequency. Night-time symptoms are common in women as well as men, and are troublesome to them.
