Purpose : This study aims to estimate the prevalence of erectile dysfunction (ED) in a population-based sample of Korean men aged 45 or over, and to study its correlation with the socio-demographic, medical and lifestyle factors.
Materials and Methods : 385 men in Chunchon City were evaluated by clinical measures and questionnaires. All the participants were evaluated for erectile dysfunction. In conjunction with this evaluation, all the men were asked to complete the International Prostate Symptom Score(IPSS), and they underwent health examinations that included blood pressure, body mass index and waist-to-hip ratio, and the laboratory studies included the fasting blood glucose and total cholesterol levels. The subjects’ medical history and health behaviors were investigated.
Results : Out of the 385 men who visited our hospital, 285 completed the questionnaires. The prevalence of moderate or severe ED increased from 5.3% in men aged 45 to 54 years to 87.3% in men aged 75 or over. The standardized prevalence of ED was 41.5%. The IPSS were strongly correlated with ED(age adjusted partial R=-0.246, p＜0.001). An increasing risk of ED was observed among those subjects with total cholesterol higher than 240mg/dl (adjusted odds ratio[aOR]=1.8), hypertension(aOR=2.2) and the ex-smokers(aOR=5.2). Education and family income were not correlated with ED(p＞0.05).
Conclusion : The results of this community-based survey confirmed the strong correlation between advancing age and the prevalence of ED. Lower urinary tract symptoms are the major factors affecting erectile function. High blood pressure, high cholesterol levels and ex-smokers are significant risk factors for ED.
