[Health investigation of 3 551 middle-aged and old males in Jiangsu Province].
OBJECTIVE
To understand the state of health of the middle-aged and old males in Jiangsu Province.


METHODS
A total number of 3 551 middle-aged and old males aged 46 approximately 69 years were randomly selected from 13 counties of Jiangsu Province. All of them received physical examinations, including laboratory tests of liver and kidney function, sugar and cholesterols, radioimmunoassay of testosterone and free testosterone levels in the serum, and B-ultrasonic examination of the prostate volume and remaining urine. They also underwent inquiries according to the International Index of Erectile Function (IIEF-5) and the questionnaire for PADAM (partial androgen deficiency of the aging male).


RESULTS
The prostate volume differed significantly (P < 0.05), while the testosterone level showed no significant difference in different age groups (P > 0.05). The level of the free testosterone in the serum descended with the increase of age. The incidence of ED and PADAM was also correlated with the increase of age.


CONCLUSIONS
In the old and middle-aged population of males, with the increase of age, sexual function decreases, the prostate volume enlarges, and the incidence of ED and PADAM obviously increases (P < 0.001).
