INCIDENCE OF ERECTILE DYSFUNCTION IN MEN 40 TO 69 YEARS OLD: LONGITUDINAL RESULTS FROM THE MASSACHUSETTS MALE AGING STUDY

Journal of Urology, 2000

Purpose: We estimated the incidence of erectile dysfunction in men 40 to 69 years old at study entry during an average 8.8-year followup, and determined how risk varied with age, socioeconomic status and medical conditions. Materials and Methods: Data from a randomly sampled population based longitudinal study of Massachusetts men were analyzed. A total of 1,709 men completed the baseline interview during 1987 to 1989 and 1,156 survivors completed followup from 1995 to 1997. The analysis sample consisted of 847 men without erectile dysfunction at baseline and with complete followup information. Erectile dysfunction was assessed by discriminant analysis of 13 questions from a self-administered sexual function questionnaire and a single global self-rating question.

Influence of age and changes over time on erectile dysfunction: results from two large cross-sectional surveys 11 years apart

Scandinavian journal of urology, 2013

The aim was to explore how erectile dysfunction (ED) correlates with increasing age and a number of demographic, physical and lifestyle factors. A questionnaire was sent to a random sample (10,458) of men living in Gothenburg, Sweden, in 1992. The men were from the age cohorts 45, 50, 55 years, etc., up to the age of 85 or older. An analogous survey was sent to a random sample (10,845) of men of age cohorts 46, 51, 56 years, etc., in 2003. The prevalence of ED from the different age cohorts assessed on the two specific occasions 11 years apart was compared with a number of factors. The response rates were 74.2% in 1992 and 68.7% in 2003. Within each survey the rate of ED increased with age at the same time as sexual activity decreased. This was paralleled by an increase in concomitant morbidity, intake of medications and alcohol consumption. The proportion of smokers and body mass index (BMI) decreased and the frequency of physical exercise increased until the age cohorts 70-71 year...

Prevalence and Risk Factors for Erectile Dysfunction in the US

The American Journal of Medicine, 2007

To assess the prevalence of erectile dysfunction and to quantify associations between putative risk factors and erectile dysfunction in the US adult male population. METHODS: Cross-sectional analysis of data from 2126 adult male participants in the 2001-2002 National Health and Nutrition Examination Survey (NHANES). Erectile dysfunction assessed by a single question during a self-paced, computer-assisted self-interview. These data are nationally representative of the noninstitutionalized adult male population in the US. RESULTS: The overall prevalence of erectile dysfunction in men aged Ն20 years was 18.4% (95% confidence interval [CI], 16.2-20.7), suggesting that erectile dysfunction affects 18 million men (95% CI, 16-20) in the US. The prevalence of erectile dysfunction was highly positively related to age but was also particularly high among men with one or more cardiovascular risk factors, men with hypertension, and men with a history of cardiovascular disease, even after age adjustment. Among men with diabetes, the crude prevalence of erectile dysfunction was 51.3% (95% CI, 41.9-60.7). In multivariable analyses, erectile dysfunction was significantly and independently associated with diabetes, lower attained education, and lack of physical activity. CONCLUSIONS: The high prevalence of erectile dysfunction among men with diabetes and hypertension suggests that screening for erectile dysfunction in these patients may be warranted. Physical activity and other measures for the prevention of cardiovascular disease and diabetes may prevent decrease in erectile function.

Prevalence of erectile dysfunction and associated factors among men without concomitant diseases: a population study

International Journal of Impotence Research, 2003

We interviewed a population sample of 2412 men aged 40-70 y in Brazil, Italy, Japan and Malaysia about medical history, lifestyle habits and sexual behavior. Men were classified as having moderate or complete erectile dysfunction (ED) if they reported to be sometimes or never able to achieve and maintain an erection satisfactory for sexual intercourse, respectively. There were 1335 men with no diagnosis of cardiovascular or prostate diseases, diabetes, ulcer or depression, nor taking hormones. The prevalence of ED was 16.1%. ED was associated with age (the risk increased 8% per y), moderate (odds ratio (OR) ¼ 2.2) or severe (OR ¼ 4.9) lower urinary tract symptoms and smoking (OR ¼ 2.3 for 430 cigarettes/day). It was inversely associated with physical activity (OR ¼ 0.5) and higher educational levels. Between the ages of 40 and 70 y, almost one in six 'healthy' men is affected by ED. Further research should look at preclinical disease stages and genetic factors.

Association between Smoking and Erectile Dysfunction: A Population-based Study

American Journal of Epidemiology, 2005

The association between smoking and erectile dysfunction was evaluated in a cohort of 2,115 Caucasian men, aged 40-79 years, randomly selected from Olmsted County, Minnesota. Smoking status was assessed by questionnaire; during the fourth biennial examination, erectile dysfunction was assessed with the Brief Male Sexual Function Inventory. Of the 1,329 men with a regular sexual partner, 173 were current smokers, 836 had previously smoked, and 203 reported erectile dysfunction. Compared with former and never smokers, current smokers in their forties had the greatest relative odds of erectile dysfunction, 2.74 (95% confidence interval (CI): 0.44, 16.89), compared with 1.38 (95% CI: 0.51, 3.74), 1.70 (95% CI: 0.82, 3.51), and 0.77 (95% CI: 0.27, 2.21) for men in their fifties, sixties, and seventies, respectively. Compared with men who never smoked, men who smoked at some time had a greater likelihood of erectile dysfunction (age-adjusted odds ratio = 1.42, 95% CI: 1.00, 2.02), and there was a dose response. Although the causal pathway underlying this association is not clear, this study contributes to the growing literature describing an association between smoking and erectile dysfunction.

Smoking as a Risk Factor for Erectile Dysfunction: Data from the Andrology Prevention Weeks 2001–2002

European Urology, 2005

Objective: To analyse the relationship between smoking and erectile dysfunction (ED). Methods: To provide further data on this issue, we analysed information gathered from men attending a free andrologic consultation in 234 Italian medical centres, in the setting of a project focused on andrologic prevention. Men were asked about ''their ability to achieve and maintain an erection sufficient for satisfactory sexual performance''. If they were dissatisfied, they were defined as having ED. Results: Out of 16724 subjects, ED was diagnosed in 4081 men (24.4%). After adjustment for age, marital status, education, alcohol consumption, physical activity and concomitant pathologies, in comparison with never smokers, men who currently smoked more than 10 cigarettes/day and former smokers showed significantly higher odds ratio (ORs 1.4 and 1.3, respectively) for ED. These results were confirmed performing analysis in strata of diabetes, hypertension, cardiovascular disease and hypercolesterolemia.

Prevalence of erectile dysfunction: a systematic review of population-based studies

International Journal of Impotence Research, 2002

A systematic review was conducted on the prevalence of erectile dysfunction (ED) in the general population. Studies were retrieved which reported prevalence rates of ED in the general population. Using a specially developed criteria list, the methodological quality of these studies was assessed and data on prevalence rates were extracted. We identified 23 studies from Europe (15), USA (5), Asia (2) and Australia (1). On our 12-item criteria list, the methodological quality ranged from 5 to 12. The prevalence of ED ranged from 2% in men younger than 40 y to 86% in men 80 y and older. Comparison between prevalence data is hampered by major methodological differences between studies, particularly in the use of various questionnaires and different definitions of ED. We stress the importance of providing all necessary information when reporting on the prevalence of ED. Moreover, international studies should be conducted to establish the true prevalence of ED across countries.
