[Epidemiological changes of ED patients: investigations in 11 Chinese cities during the past 5 years].
OBJECTIVE
To investigate the epidemiological changes of erectile dysfunction (ED) patients in the past five years.


METHODS
In 2003 and 2008, we conducted two questionnaire investigations on the epidemiological changes of ED outpatients in 11 Chinese cities in such aspects as age, disease course, ED severity, smoking and drinking habits, accompanying hypertension, diabetes and coronary heart disease (CHD), and sexual intercourse satisfaction.


RESULTS
According to the valid copies of the questionnaire collected (808 in 2003 and 858 in 2008), the age pattern of the ED patients hardly changed in the past five years, over 60% aged 30 - 50 years. Compared with the results obtained in 2003, the second investigation showed obvious increases in the following numbers of the ED patients: by 13% in those with longer disease courses (5 - 10 yr), from 24.1 to 42.9% in those with moderate ED, from 20.4 to 29.9% in those with severe ED, by at least 10% in those with smoking and drinking habits, from 11.5 to 16.2% in those with hypertension, from 9.4 to 13.5% in those with diabetes, and from 57.6 to 73.3% in those without sexual satisfaction, while the number of those with CHD did not change significantly.


CONCLUSIONS
Increased unhealthy living habits and erectile function impairing diseases have added to the incidence and severity of ED. There is still much work to be done in the prevention and early treatment of ED.
