Nocturia at the Population Level in Poland: Prevalence, Bother, Quality of Life, and Treatment-Related Behavior

Background and Objectives: The purpose of this study was to measure at the population level the prevalence, bother, effect on quality of life, and behavior associated with treatment for nocturia in a large representative cohort of Polish adults aged >= 40 years. Materials and Methods: Data were derived from LUTS POLAND, a computer-assisted telephone survey of urological health that mirrored the entire Polish population in urban and rural areas. Results: Six thousand persons completed the survey. The respondents were representative for age, sex, and place of residence. Nocturia was highly prevalent because 73.7% of all participants reported >= 1 nocturia episode, and 36.1% reported >= 2 nocturia episodes. We did not identify differences between urban and rural areas. Women were more often affected than men, and the prevalence of nocturia increased with age. More than one-third (29.7-45.3%) of respondents who reported nocturia were bothered by the symptom and, thereby, concerned about their urinary-specific quality of life. Notably, we found a statistically significant correlation between the frequency of nocturia and intensification of its bother (p < 0.001 for men and women). However, only about one-fourth (22.2-29.2%) of respondents with nocturia sought treatment, most of whom received treatment. Conclusions: Nocturia was highly prevalent and often bothersome with negative effects on quality of life of Polish adults aged >= 40 years. However, the percentage of treatment seeking was low. Combined with the fact that nocturia has multiple causes and consequences, including high morbidity and mortality, our findings revealed that nocturia was a significant public health issue. We need to develop strategies to specifically increase awareness about nocturia and provide greater healthcare and financial resources for persons with nocturia in Poland.
