Feb. 1, 2007 -- More than 18 million American men suffer from erectile dysfunctionerectile dysfunction, but help may not require a little pill.
A new study from Johns Hopkins' Bloomberg School of Public Health shows nearly one in five men experience erectile dysfunction, but simple lifestyle changes may be enough to ward off the problem.
Erectile dysfunction was much more common among men with diabetesdiabetes or other risk factors for heart diseaseheart disease and those who were physically inactive, the researchers found.
"The associations of erectile dysfunction with diabetes and cardiovascular risk factors may serve as powerful motivators for men who need to make changes in their diet and lifestyle," says researcher Elizabeth Selvin, PhD, MPH, of the department of epidemiology at the Bloomberg School of Public Health, in Baltimore, in a news release.
ED Common Among American Men
In the study, researchers examined the prevalence of erectile dysfunction and its association with other health problems in a sample of more than 2,100 men, aged 20 and older, who took part in a nationwide survey in 2001-2002.
Researchers classified men who reported being "sometimes able" or "never able" to get and keep an erection as having erectile dysfunction.
The results showed 18.4% of men over 20 suffered from erectile dysfunction.
The problem was much more common in older men, with 70% of men 70 or over reporting erectile problems, compared with 5% of men 20 to 40.
Healthy Lifestyle May Prevent ED
Aside from showing how widespread erectile dysfunction is, researchers say the results are significant because they suggest simple lifestyle changes like regular exercise and eating a healthy diet may ease the problem for many men by reducing the risk of heart disease and associated conditions.
The study showed that men with heart disease risk factors, diabetes, or a sedentary lifestyle were much more likely to report erectile dysfunction than healthier, more physically active men.
For example:
Researchers say the association between ED and lack of physical activity suggests lifestyle changes, especially increasing exercise levels, may be effective, drug-free ways to treat and prevent erectile dysfunction.
The results appear in the American Journal of Medicine.
