Nocturnal polyuria in community‐dwelling women

Abstract

OBJECTIVETo determine the age prevalence of nocturnal polyuria among older women in the community, and to investigate the relationship between nocturnal polyuria and nocturia. PATIENTS AND METHODSIn all, 1183 women aged ≥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. RESULTSThere 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. CONCLUSIONNocturnal 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.

Obstructive Sleep Apnea in a Danish Population of Men and Women Aged 60-80 Years with Nocturia

“…41 This finding corresponds with studies by Swithinbank et al (women), 30 Rembratt et al (men and women), 31 and Massolt et al (incontinent women) 32 who found a markedly higher frequency of nocturnal polyuria in subjects having nocturia (≥ 2 voids) compared to no nocturia.…”

A Cutoff Value Based on Analysis of a Reference Population Decreases Overestimation of the Prevalence of Nocturnal Polyuria

“…Since publication of the ICS standardization report, several groups have used the ICS definition with 33% cutoff to present the percent of patients with or without NP. 1,4,8,10,[12][13][14][15][16] Others reported actual NPI values as the mean or sometimes as the median while a minority provided an indication of the variation by presenting the range, 17,18 SD 11,19 or percentile. 20 Of 14 studies including a total of 2,266 subjects, in which there is some overlap due to repeat use of data, we calculated a weighted mean NPI of 33%.…”

Correlates for nocturia: A review of epidemiological studies

“…16,36 In contrast, Swithinbank et al reported that daytime urinary frequency has no relationship with nocturia or nocturnal polyuria in women. 93 No studies have reported an association between nocturia and voiding symptoms.…”
