- Purpose: To elucidate the longitudinal changes in the prevalence of lower urinary tract dysfunction (LUTD) according to age over the past 10 years.
Materials and Methods: The changes in the proportion of prevalence for LUTD, including benign prostatic hyperplasia (BPH) and urinary incontinence (UI) among South Koreans from 2009 to 2018, were analyzed using the National Health Information Database established by the Korean National Health Insurance Service. All conditions were defined according to the corresponding Korean Standard Classification of Diseases-8 for diagnosis and surgical procedures and Health Insurance Review & Assessment Service codes for drugs.
Results: The 60-69, 70-79, and over 80 age groups accounted for more than 60% of the LUTD cases from 2009 to 2018, while significant increases in the crude prevalence of LUTD were observed over a 10-year period in all age groups (p for trend <0.05). In age groups over 60 years, LUTD was more prevalent in men than women, but there was no statistically significant difference in proportion (p>0.05). The changes in the prevalence and prevalence proportion exhibited similar trends in BPH, UI, and LUTD.
Conclusions: LUTD was more prevalent in the elderly aged over 60 years old than in younger adults. Therefore, this study suggests the development of nationwide healthcare policies to manage LUTD in the elderly population of South Korea, which is expected to become the world’s most aged population.
