Prevalence and risk factors for erectile dysfunction in 2869 men using a validated questionnaire.

PURPOSE: To assess prevalence and risk factors for erectile dysfunction (ED) by using the International Index of Erectile Function- 5 (IIEF-5) in men undergoing a health investigation. METHODS: Men aged 20-80 years participating in a health-screening project in the area of Vienna completed the IIEF-5 for evaluation of ED. In parallel, all men underwent a detailed health examination including physical assessment, evaluation of various life-style factors, medical history and a blood analysis. RESULTS: A total of 2869 men were analysed. According to the IIEF-5 score, 32.2% reported on any degree of ED (IIEF-5 score <22), 23.7% had mild ED (IIEF-5 score 17-21), 5.0% mild to moderate ED (IIEF-5 score 12-16), 2.2% moderate ED (IIEF-5 score 8-11) and 1.3% severe ED (IIEF-5 score 5-7). The proportion of men with ED remained stable from 20 to 50 years (26-29%) and increased thereafter to 37.5% (51-60 years) and to 71.2% in those 71-80 years of age. Severe ED (IIEF-5 score 5-7) increased from 0.4% (20-30 years) to 0.5% (41-50 years), 1.3% (51-60 years) and to 9.6% in those aged 71-80 years. Risk factors for ED were age, diabetes (OR: 3.0; 95%CI: 1.53-5.87), hyperlipidemia (OR: 2.29; 95%CI: 1.42-3.7), lower urinary tract symptoms (OR: 2.2; 95%CI: 1.76-2.76), hypertension (OR: 2.05; 95%CI: 1.61-2.6), psychological stress (OR: 1.68; 95%CI: 1.43-1.98) and low physical activity (OR: 1.35; 95%CI: 1.15-1.6) (all, p < 0.05). CONCLUSION: Overall, 32.2% of men in our study had ED according to the IIEF-5. Apart from age, most important risk factors for ED were diabetes, hyperlipidemia, lower urinary tract symptoms, hypertension and psychological stress.

Is erectile dysfunction an indicator for increased risk of coronary heart disease and stroke?

BACKGROUND: Considered to be a manifestation of a generalized vascular disease, erectile dysfunction (ED) could serve as an indicator for future cardiovascular events. Aim of this study was therefore to evaluate the role of ED as a predictor for coronary heart disease (CHD) and stroke. METHODS: Men participating in a health-screening project in the area of Vienna completed the International Index of Erectile Function-5 questionnaire (IIEF5) to assess prevalence and severity of ED. Additionally, all men underwent a detailed health examination. The risk for CHD or stroke within 10 years depending on the severity of ED was estimated according to Framingham risk profile algorithms. RESULTS: In the CHD risk cohort (n = 2.495; 46.2 +/- 9.9 yrs) men with moderate/severe ED (IIEF5 5-16; n = 163) had a 65% increased relative risk for developing CHD within 10 yrs compared to those without ED (IIEF5 22-25; n = 1.784) (absolute risk: 8.0% for no ED to 13.2% for moderate/severe ED; p < 0.001). Relative risk increase ranged from 13.9% for those aged 30-39 yrs (p = 0.121), to 42.2% for 40-49 yrs (p = 0.012), 27.7% for 50-59 yrs (p = 0.048) and 27.1% for 60-69 yrs (p = 0.021). In the stroke risk population (n = 644; 61.3 +/- 5.1 yrs) men with moderate/severe ED (n = 99) were at a 43% relative risk increase for a stroke within 10 years (absolute risk: 9.3% for no ED to 13.3% for moderate/severe ED; p = 0.041). Increased risk varied between 38.6% for men aged 55-59 yrs (p = 0.013), 24.7% for 60-64 yrs (p = 0.072), 35.9% for 65-69 yrs (p = 0.046) and 43.6% for 70-74 yrs (p = 0.049). CONCLUSIONS: Moderate to severe ED, but not mild ED is associated with a considerably increased risk for CHD or stroke within 10 years. A thorough medical surveillance seems therefore advisable for men with ED including cardiological evaluation, treatment of risk factors and lifestyle modifications.

Association between lower urinary tract symptoms and erectile dysfunction.

OBJECTIVES: To assess whether the association between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) is confounded by age or whether LUTS represent an independent risk factor for ED. METHODS: Men aged 20 to 80 years, who were participating in a health-screening project in the area of Vienna, completed the International Prostate Symptom Score (IPSS) and the International Index of Erectile Function-5. In parallel, all men underwent a detailed health evaluation, including physical examination, evaluation of various lifestyle factors, and a blood laboratory study with 14 parameters. RESULTS: Within the total study population (n = 2858; mean age 45.8 years, range 20 to 80), the prevalence of LUTS and ED increased statistically significantly with age (P <0.0001). In multivariate analysis controlling for age, comorbidities, and lifestyle, the IPSS (P = 0.0001), the obstructive score of the IPSS (P = 0.0001), nocturia (P = 0.04), and the LUTS bother score (P = 0.002) correlated statistically significantly with the presence of ED (International Index of Erectile Function-5 score less than 22). The odds ratio for the presence of ED was 2.2 (95% confidence interval [CI] 1.8 to 2.8) for LUTS (IPSS greater than 7), 2.0 (95% CI 1.7 to 2.4) for voiding symptoms, 1.4 (95% CI 1.1 to 1.7) for nocturia (score greater than 2), and 2.5 (95% CI 2.0 to 3.1) for the LUTS bother score. CONCLUSIONS: The presence of LUTS, in particular voiding symptoms, nocturia, and the quality-of-life impairment due to LUTS, is an independent risk factor for the presence of ED. These findings have implications for the treatment of elderly men with LUTS and open a new area for research.
