Decadal changes in nocturia among American middle-aged and older men.

Abstract

To estimate the prevalence of nocturia in middle-aged and elderly men and evaluate its associated factors and changes over time. Data of middle-aged and older men aged ≥40 years from the 2007-2008 and 2017-2020 cycles of the National Health and Nutrition Examination Survey were retrospectively analyzed. The prevalence of nocturia was estimated using participant questionnaires on nocturia, lifestyle-related factors, and health factors, and its decadal changes were examined using multivariate logistic regression analysis to determine related factors associated with the prevalence of nocturia. The prevalence of nocturia was 38.0% in 2007-2008 and 39.6% in 2017-2020, with no significant increase observed (P = 0.3989). Being a non-Hispanic black was positively correlated with nocturia (adjusted odds ratio [AOR] = 1.54, 1.22-1.93, P < 0.001), whereas the correlation with being a Mexican American disappeared (AOR = 1.25, 0.90-1.73, P = 0.187). Diabetes (AOR = 1.32, 1.07-1.64, P = 0.010) and sleep disorders (AOR = 1.31, 1.07-1.60, P = 0.008) showed a statistically significant positive correlation with nocturia, whereas a significant negative correlation was observed between employment (AOR = 0.66, 0.54-0.82, P < 0.001) and nocturia. Above-high-school education (AOR = 0.60, 0.47-0.76, P < 0.001) showed a constant trend toward a negative correlation with nocturia. The correlation between high school education or general educational development and nocturia disappeared (AOR = 0.81, 0.62-1.05, P = 0.112). Diabetes and sleep disorders contribute to the development of nocturia, while work and high educational attainment can actively combat nocturia. Geriatr Gerontol Int 2024; ••: ••-••.
