Health-related quality of life associated with lower urinary tract symptoms in four countries.
OBJECTIVE
To describe health-related quality of life (HRQL) associated with lower urinary tract symptoms (LUTS) assessed by validated questionnaires in four countries.


METHODS
More than 6000 men, recruited by using community- or population-based sampling in four countries, completed questionnaires soliciting information about urinary symptom frequency, bother, degree of interference with daily activities, and other measures of HRQL.


RESULTS
In all countries, disease-specific HRQL worsened with increasing age. Adjusting for age, most disease-specific HRQL measures were significantly worse with increasing symptom severity. The correlation between symptoms and HRQL was strongest in countries with higher prevalence of symptoms, such as Japan or the United States, and less pronounced in countries with lower prevalence (France, Scotland), possibly reflecting the lower variability in scores.


CONCLUSIONS
HRQL measures are worse in older men, and increased urinary symptom severity is associated with worse disease-specific HRQL in all countries, despite potential cross-cultural differences in disease prevalence, medication use, perceptions, or willingness to report symptoms or worse HRQL. This cross-cultural consistency suggests that an assessment of symptom bother or interference with daily activities may be useful in patient evaluation.
