Is the metabolic syndrome an independent risk factor for erectile dysfunction?

PURPOSE: We determined the role of the metabolic syndrome as an independent risk factor for erectile dysfunction. MATERIALS AND METHODS: Men participating in a health screening project completed the International Index of Erectile Function-5. The metabolic syndrome was defined according to the 2005 International Diabetes Federation consensus definition. Multiple linear regression, ANOVA and chi-square tests were used to investigate the impact of the metabolic syndrome on erectile dysfunction. RESULTS: A total of 2,371 men with a mean age of 46.1 years (SD 9.9, range 30 to 69) were analyzed. Of the men 33.4% (652) had no erectile dysfunction (International Index of Erectile Function-5 score 22 to 25), 59.7% (1,166) had mild erectile dysfunction (International Index of Erectile Function-5 score 17 to 21) and 6.9% (134) had moderate to severe erectile dysfunction (International Index of Erectile Function-5 score 5 to 16). The metabolic syndrome was present in 33.8% (794). In a multiple linear regression analysis an increased waist-to-hip ratio (p = 0.01) and metabolic syndrome (p = 0.01) turned out to be independently associated with a decreased International Index of Erectile Function-5 score. When stratified according to age, the metabolic syndrome was correlated to erectile dysfunction only in men 50 years old or older with an increase of severe erectile dysfunction by 48% (p = 0.01). CONCLUSIONS: The metabolic syndrome and an increased waist-to-hip ratio are independently associated with a decreased International Index of Erectile Function-5 score. The metabolic syndrome in men older than 50 years is significantly associated with a higher proportion of moderate to severe erectile dysfunction.

Prevalence and correlates for interstitial cystitis symptoms in women participating in a health screening project.

OBJECTIVES: To determine the prevalence of interstitial cystitis (IC) symptoms in an urban female population, to study their impact on quality of life and sexual function, and to identify correlates for IC symptoms. METHODS: Women attending a voluntary health survey project in Vienna underwent a detailed health investigation and completed a questionnaire containing the O'Leary-Sant IC questionnaire. Women with high (> or =12) symptom and problem scores including nocturia (>2) and pain were considered most likely to have IC. RESULTS: A total of 981 women, aged 19 to 89 yr (mean, 49.1+/-14.7 yr), participated in the study. Of these, 57.9% had a low IC symptom score (score 0-3), 25.9% mild IC symptoms (score 4-6), 13.9% moderate symptoms (score 7-11), and 2.3% a high symptom score (score 12-20). The IC problem score revealed a similar pattern. The overall prevalence of IC was 306/100,000 women with the highest value (464/100,000) in middle-aged women (40-59 yr). About two thirds of the women with moderate to high risk for IC reported an impairment of quality of life; 35% reported an effect on their sexual life. In a multivariate analysis, bowel disorders (p=0.016) and psychological stress (p=0.029) were correlated to the probability of IC. CONCLUSION: The prevalence of IC symptoms is higher than previously estimated and substantially affects quality of life and sexuality.

Incidence and remission of female urinary incontinence over 6.5 years: analysis of a health screening project.

OBJECTIVES: To analyse the incidence and remission of female urinary incontinence (UI) over 6.5 years and to identify risk factors for the development of UI. METHODS: Women who underwent a health investigation in 1998 or 1999 in the area of Vienna completed the Bristol Female Lower Urinary Tract Symptoms questionnaire. In 2005, all women (n=925) aged >/=20 yr in 1999 who were still living in the area of Vienna were invited to recomplete the questionnaire. RESULTS: The response rate was 47.7% (n=441; age range, 20-84 yr), and the mean follow-up was 6.5 yr. The overall prevalence of UI was 32% at baseline and increased to 43% in 6.5 years. The mean annual cumulative incidence of UI was 3.9%, with the lowest rate (2.3%) in the youngest age group (20-39 yr) and the highest (7.3%) in those aged 70 yr or older. The mean annual full remission rate was 2.9%, with no clear age dependency. More than half (55.6%) of the women with a full remission had only a mild form of UI at baseline. In a multivariate analysis, urgency (p=0.008) and age (p=0.024) were correlated to the risk of de novo UI. CONCLUSIONS: This longitudinal study demonstrates that UI is not necessarily a progressive process but rather is a dynamic one.

The association between vascular risk factors and lower urinary tract symptoms in both sexes.

OBJECTIVES: To test the potential role of atherosclerosis in the development of lower urinary tract symptoms (LUTS), we investigated the association between vascular risk factors and LUTS in both sexes. METHODS: Men and women participating in a health screening project completed the International Prostate Symptom Score (IPSS). In parallel all individuals underwent a detailed health investigation with assessment of diabetes mellitus, hypertension, hyperlipidemia, and nicotine use. RESULTS: A total of 1724 men (52.3+/-9.1yr, mean+/-standard deviation; IPSS: 6.3+/-4.3) and 812 women (56.0+/-9.9 yr; IPSS: 5.2+/-4.9) entered the study. A total of 62.5% (n=1077) of men had no vascular risk factor, 32.1% (n=554) one, and 5.4% (n=93) two or more; the corresponding figures for women were 64.7% (n=525), 30.7% (n=249), and 4.7% (n=38). In men, the IPSS was identical in those with no (6.2+/-4.1) and one (6.2+/-4.4) vascular risk factor yet increased to 7.7+/-5.5 (+24.2%) in those with two or more risk factors (p=0.01). In women, the IPSS increased from 4.8+/-4.6 in those with no vascular risk factor to 5.7+/-5.3 (+18.7%) with one and 7.0+/-5.7 (+45.8%) with two or more factors (p=0.05). CONCLUSIONS: Our data suggest that vascular risk factors play a role in the development of LUTS in both sexes. This observation opens new aspects in our understanding of the pathogenesis of LUTS and warrants future studies.

The association between lower urinary tract symptoms and renal function in men: a cross-sectional and 5-year longitudinal analysis.

PURPOSE: We assessed the association between LUTS and renal function in men in a cross-sectional and a longitudinal study. MATERIALS AND METHODS: Men participating in health investigation in Vienna entered this study. In the cross-sectional analysis a consecutive series of men were studied and in the longitudinal analysis men were reevaluated after 5 years. LUTS were assessed by I-PSS and renal function was evaluated by GFR, as calculated by the Cockcroft-Gault equation. RESULTS: A total of 2.469 men with a mean age of 47.1 years (range 30 to 80) entered the cross-sectional study and 439 with a mean age of 51.7 years (range 45 to 79) could be assessed in longitudinal analysis. In the cross-sectional study there was no association between the degree of LUTS and GFR during 5 life decades (p = 0.55). An identical pattern was observed for irritative and obstructive scores. In the longitudinal cohort mean GFR +/- SD decreased from 84.3 +/- 20.2 ml per minute at baseline to 79.2 +/- 18.7 ml per minute after 5 years (-6.0%, p <0.0001). The mean decrease in GFR after 5 years was 4.5 ml per minute (-5.4%) in men without/mild LUTS (I-PSS 7 or less at ages 55.4 +/- 11.0 years), 3.9 ml per minute (-4.9%) in those with moderate LUTS (I-PSS 8 to 20 at ages 61.3 +/- 11.6 years) and 4.2 ml per minute (-5.2%) in those with severe LUTS (I-PSS greater than 20 at ages 64.3 +/- 7.4 years). On linear regression analysis in the 2 study cohorts neither I-PSS, nor obstructive or irritative score affected GFR (p >0.05). The only determinants for GFR less than 90 ml per minute were age (p <0.0001) and hypertension (p <0.0001). CONCLUSIONS: LUTS do not represent an independent risk factor for impaired renal function in men.

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.

Prevalence of the overactive bladder syndrome by applying the International Continence Society definition.

PURPOSE: To determine the prevalence of the overactive bladder (OAB) syndrome in an urban population by using the International Continence Society (ICS) definition and to determine its impact on quality of life and sexual function. METHODS: Women and men participating in a health screening project in the area of Vienna completed the Bristol Lower Urinary Tract Symptoms (LUTS) questionnaire. To assess the prevalence of OAB the 2002 ICS definition was applied. In addition, all participants underwent a detailed health examination, including physical assessment, evaluation of life style factors, laboratory study and urinalysis. RESULTS: A total of 1199 men and 1219 women aged 20-91 years were analysed. The prevalence of OAB in men (48.5+/-13.1 years) was 10.2% (OABdry: 8.4%; OABwet: 1.8%) and 16.8% in women (49.5+/-13.5 years; OABdry:10.3%; OABwet: 6.5%). In women, the prevalence of OABdry remained fairly stable over 6 life decades, while OABwet increased substantially after the age of 40 years. In men OABwet and OABdry increased after the third life decade. In men with OAB, 48% did not report a negative impact on quality of life, 36% had minimal, 9.8% moderate and 2.5% severe impairment; the respective percentages for women were 53%, 33%, 7.3% and 6.3%. OABwet had a more profound impact on quality of life. A negative impact of OAB on sexuality was reported by 24% of men and 31% of women. CONCLUSION: The high prevalence of OAB in this population, its negative impact of quality of life and sexuality underline the importance of this syndrome.

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.

Female sexual dysfunction in a healthy Austrian cohort: prevalence and risk factors.

PURPOSE: Data on prevalence and risk factors for female sexual dysfunction (FSD) are rare, particularly from Europe. Aim of our study was therefore to investigate this issue in a cohort of women undergoing a health investigation. PATIENTS AND METHODS: A consecutive series of women aged 20-80 years participating in a health-screening project in Vienna underwent a detailed health investigation and completed a 23-item questionnaire on several aspects of FSD including desire, arousal, pain and orgasmic disorders. Prevalence of FSD in different age groups and risk factors for FSD were calculated. RESULTS: A total of 703 women aged 43+/-15 years entered this study. Within the total study population, 22% reported on desire disorders, 35% on arousal disorders, and 39% on orgasmic problems, all of which increased significantly with age. Pain disorders were reported by 12.8% being most frequently in the women aged 20-39 years. In women aged 60-69 years, still 50% reported having at least "occasionally" sexual desire and 30% had more than two sexual intercourses per month. In this age group, 50% stated that a healthy sexual life is at least moderately important to them. Apart from age few risk factors for FSD were identified. Sportive activity was the only correlate to desire- and arousal disorders, psychological stress for orgasmic disorders. CONCLUSIONS: This study provides insights into age-specific changes of FSD in apparently healthy women. The importance of this subject is underlined by the high prevalence of FSD particularly in the elderly paralleled by a persisting interest in sexual activity.

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.

Prevalence and risk factors for erectile dysfunction in Austria--analysis of a health screening project.

PURPOSE: The aim of this study was to determine prevalence and risk factors for erectile dysfunction (ED) in men undergoing a health investigation. METHODS: Men aged 30-69 yrs participating in a health screening project in the area of Vienna completed a 11-item questionnaire on ED which was extracted from the international index of erectile function (IIEF). In parallel, all men underwent a detailed health examination including physical assessment, evaluation of various life-style factors and a blood analysis with 14 parameters. RESULTS: Within the total study population (n = 832; 45.3 +/- 9.8 yrs), 8.2% reported no sexual intercourse during the previous four weeks, 5.1% reported moderate/severe ED, 13.1% mild and 73.6% no ED. ED, defined as any problem in maintaining erection until the end of sexual intercourse, increased from 12.5% in those aged 30-39 yrs to 15.3% at 40-49 yrs, 27.4% at 50-59 yrs and 45.2% in men 60-69 yrs. In parallel, the percentage of men without sexual intercourse during the previous four weeks increased from 7.4% at 30-39 yrs to 8.8% at 50-59 yrs and 17.0% at 60-69 yrs. By far the strongest correlate for ED was age; other factors were cardiovascular diseases, physical activity and diabetes mellitus. CONCLUSIONS: This study provides the first estimate of the prevalence of ED in different life decades of men in Vienna, and identifies a number of risk factors for this highly prevalent disorder in ageing men.

Serum androgen levels in men: impact of health status and age.

OBJECTIVES: To investigate the impact of health status on androgen levels in men and to assess the age-related changes in androgen levels. METHODS: Sera were obtained from 526 men (age 20 to 89 years) participating in a health screening project and 35 men selected according to the SENIEUR protocol, which excludes those with underlying disease. The health screening project participants were divided into two groups: healthy men (n = 133; group 1) and the remainder (n = 393; group 2). The total testosterone and sex hormone-binding globulin levels were quantified, and the amount of free testosterone (cfT) was calculated. RESULTS: The lowest annual declines in androgen level were observed in group 3 (testosterone 0.2%; cfT 0.4%), followed by group 1 (testosterone 0.4%; cfT 0.8%) and group 2 (testosterone 0.8%; cfT 0.9%). Body mass index and levels of cholesterol, triglycerides, and glucose correlated negatively (P <0.01) with testosterone and cfT. Decade-adjusted reference values (mean +/- 2 standard deviations) for testosterone and cfT were defined. The proposed lower testosterone reference value declined gradually from 3.1 ng/mL (20 to 29 years) to 1.7 ng/mL (70 years or older). CONCLUSIONS: In this cross-sectional study, serum androgens declined in aging men, and the extent of this decrease correlated with health status. A fixed, non-age-adjusted reference value does not adequately reflect this and might lead to a false diagnosis of androgen deficiency, particularly in elderly men. The clinical value of age-related reference values, however, needs to be determined in prospective studies.

The natural history of lower urinary tract symptoms over five years.

OBJECTIVES: To assess the natural history of lower urinary tract symptoms (LUTS) in a cohort of previously untreated men over five years. METHODS: Men participating in a health-screening project completed the International Prostate Symptom Score (IPSS) in 1996. In 2001, men older than 45 years with no prostate surgery or LUTS-specific medication before 1996 completed the IPSS plus a questionnaire on several aspects of LUTS. At the same time, all men underwent a health examination in 1996 and 2001. RESULTS: A total 456 men aged 52+/-12 years (range: 40-84) at baseline completed the 5-year follow-up. Mean IPSS increased from 4.6 to 5.5 (+20%; p<0.0001) and the IPSS-Ql from 0.8 to 1.1 (+38%; p<0.0001) over five years. Progression of IPSS and IPSS-Ql were highly correlated. No change of IPSS was reported by 19%, a worsening by 50% and an improvement by 31%. Not all aspects of LUTS progressed in a similar pattern, storage symptoms had a higher tendency to improve over time. Medical therapy was initiated in 7%, 39% and 67% of those with mild, moderate or severe LUTS at baseline, respectively. In a multivariate analysis age and degree of being bothered by LUTS were independent predictors for initiation of therapy. CONCLUSIONS: This 5-year longitudinal study of men without previous LUTS treatment demonstrates the slow nature of the disease's progression. Not all aspects of LUTS progress in a similar pattern. Initiation of therapy is influenced by patient age and by the degree of being bothered by LUTS.

Body mass index is the main risk factor for arterial hypertension in young subjects without major comorbidity.

BACKGROUND: Analytical statistics revealed a variety of risk factors for hypertension, but the complex interplay between different factors remains to be determined by more powerful statistical techniques. METHODS: Analytical as well as new, explorative statistical methods such as natural segmentation (k-means) and predictive modelling algorithms (C4.5) were used to classify the interactions of the individual risk factors for arterial hypertension in a large cohort of subjects. Fifty-five attributes (subject base, sociodemographic, medical history, laboratory data) were obtained from each of the 3547 participants of a community-based health survey. The study subjects, mean age of 41 years, were free of major comorbidity. RESULTS: Twenty-five percent of the subjects had at least stage 1 hypertension. No clear linear dependency of risk factors with the diagnosis hypertension could be derived by the analytical statistics. In particular, the mutual amplification of different risk factors towards hypertension could not be revealed by these techniques. Explorative analytics however, uncovered body mass index (BMI) as the main single risk factor associated with hypertension. High predictive accuracy was achieved when combinations of certain risk factors including male gender and age were used. CONCLUSIONS: In summary, the survey of risk factors for hypertension using explorative analytics yielded high increases for the correct prediction of arterial hypertension. In this cohort, BMI was the single strongest parameter associated with arterial hypertension.
