The Impact of Lower Urinary Tract Symptoms on Quality of Life, Work Productivity, Depressive Symptoms, and Sexuality in Korean Men Aged 40 Years and Older: A Population-Based Survey

PURPOSE To examine the impact of lower urinary tract symptoms (LUTS) on health-related quality of life (HRQoL) in Korean men aged ≥40 years. METHODS A population-based, cross-sectional door-to-door survey was conducted among men aged ≥40 years. Individuals with LUTS were defined as men reporting at least one LUTS using 2002 International Continence Society definitions. Structuredquestionnaires were used to assess several dimensions of HRQoL, including generic health status (EuroQoL-five-dimensions questionnaire), work productivity (work productivity and activity impairment questionnaire), depressive symptoms(center for epidemiologic studies depression scale), and sexual health (sexual satisfaction and erectile dysfunction). The impact of LUTS was assessed by comparing several dimensions of HRQoL among men with and without LUTS. RESULTS Of the 1,842 participants, 1,536 (83.4%) reported having at least one LUTS. The prevalence of LUTS increased with age (78.3% among those aged 40-49 years to 89.6% among those aged 60 years or older). Those with LUTS reported a significantlylower level of generic health status and worse work productivity compared with those without LUTS. Significantly more individuals with LUTS reported having a higher level of major depressive symptoms compared with those without LUTS.Those with LUTS reported worse sexual activity and enjoyment, and were significantly more likely to have erectile dysfunction than those without LUTS. CONCLUSIONS LUTS seem to have a substantial impact on several dimensions of HRQoL in Korean men aged ≥40 years.
