Abstract

PURPOSE
The aim of this study was to investigate the relationship between lower urinary tract symptoms (LUTS) and risk factors for vascular diseases in a population-based cohort study, the Hallym Aging Study (HAS).
MATERIALS AND METHODS
Among the 1,520 participants in HAS, 280 men aged more than 50 years, who underwent detailed health evaluations, including health-related questionnaires, evaluations of their medical history, and various life style factors, as well as clinical measurements, were included in the study. Vascular risk factors used in the present study including hypertension, diabetes mellitus, hyperlipidemia, and smoking and were assessed by medical history and clinical measurements. LUTS were assessed by validated questionnaires, the International Prostate Symptom Score (IPSS), and the relationship between LUTS and vascular risk factors was investigated.
RESULTS
Of the 280 men, 175 (62.5%) had moderate/severe LUTS (IPSS>7) and 260 (93%) had one or more vascular risk factors. The IPSS was similar in those with no (11.6+/-9.7) and one or two (11.5+/-8.5) vascular risk factors, but increased to 15.1+/-9.3 in those with 3 or more vascular risk factors (p<0.05). The multiple logistic regression analysis, controlling for age and body mass index (BMI) showed that men with 3 or more vascular risk factors were 3 times more likely to have moderate/severe LUTS than men without vascular risk factors (p<0.05).
CONCLUSIONS
Men with risk factors for vascular diseases are more likely to have LUTS and these findings suggest that vascular risk factors play a role in the development of LUTS.
