Prevalence and Correlates of Nocturia in Community‐Dwelling Older Adults

Abstract

Objectives To determine the prevalence and correlates of nocturia in community-dwelling older adults. Design Planned secondary analysis of cross-sectional data from the University of Alabama at Birmingham Study of Aging population-based survey. Setting Participants’ homes. Participants One thousand older adults (aged 65 to 106 years) recruited from Medicare beneficiary lists between 1999 and 2001. The sample was selected to include 25% African American women, 25% African American men, 25% white women, and 25% white men. Measurements In-person interviews included socio-demographic information, medical history, Mini-Mental State Examination, and measurement of body mass index (BMI). Nocturia was defined in the main analyses as getting up 2 or more times per night to void. Results Nocturia was more common among men than women (63.2% vs. 53.8%, OR=1.48, 95% CI=1.15–1.91, P=.003) and more common among African Americans than whites (66.3% vs. 50.9%, OR=1.89, CI=1.46–2.45, P< .0001). In multiple backward elimination regression analysis in men, nocturia was significantly associated with African American race (OR=1.54) and BMI (OR=1.22 per 5 kg/m2). Higher MMSE was protective (OR=0.96). In women, nocturia was associated with older age (OR=1.21 per 5 years), African American race (OR=1.64), history of any urine leakage (OR=2.17), swelling in feet and legs (OR=1.67), and hypertension (OR=1.62). Higher education was protective (OR=0.92). Conclusion Nocturia in community-dwelling older adults is a common symptom associated with male gender, African-American race, and some medical conditions. Given the significant morbidity associated with nocturia, any evaluation of lower urinary tract symptoms should include assessment for the presence of nocturia.

Nocturia, Insomnia Symptoms and Mortality among Older Men: The Health, Aging and Body Composition Study

“…Furthermore, the current study included older men only, while previous studies that reported association between nocturia episodes and falls included both men and women. Similar to reports from previous studies, 8,35,36 prevalence of nocturia was significantly higher among black older men than white older men (Table 1); however, after stratification of participants by education status, the relationship between nocturia and race was only significant among those with lower education level (< 12 years of education). Further research would be needed to clarify whether socioeconomic related factors explain the association between race and nocturia frequency found in the current study.…”

Incontinência urinária e noctúria: prevalência e impacto sobre qualidade de vida em idosas numa Unidade Básica de Saúde

“…[5][6][7][8][9][10][11]15,16 Neste estudo, foi utilizada uma amostra de conveniência composta por 66 idosas que compareceram para vacinação contra influenza. A prevalência de IU, de acordo com as respostas ao questionário de triagem ICIQ-SF, foi mais próxima àquela observada em estudo com 40 mulheres recrutadas em instituições para idosos,6 e mais elevada que a prevalência observada nos estudos feitos em populações brasileiras com idades semelhantes.…”

Correlates for nocturia: A review of epidemiological studies

“…[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]78,79 Many cross-sectional studies after the millennium have shown an independent association of older age with nocturia after multivariate analysis.…”

“…13,16,27 Tikkinen et al reported that women younger than 50 years had more nocturia than men of the same age, but that the prevalence of nocturia increased twice as rapidly in men as among women with aging. 34 In a study by Bing et al, the prevalence of nocturia was found to be similar in men and women.…”
