odds ratio.
To determine, using the Asian Survey of Aging Males (ASAM), the
prevalence of lower urinary tract symptoms (LUTS) and sexual disorders in
Asian men aged 50–80 years, and to investigate the relationship between LUTS
and sexual dysfunction, as community-based studies have shown a relationship
between LUTS and sexual dysfunction.
SUBJECTS AND METHODS
The ASAM survey was conducted in selected cities in five Asian countries,
using a combination of face-to-face and mail-survey methods. The survey
evaluated demographics, urinary symptoms (using the International Prostate
Symptom Score, IPSS, and bother score), functional problems (using the
Danish Prostatic Symptoms Score, DAN-PSS-Sex, and International Index of
Erectile Function, IIEF) and comorbidity factors. In all, 1155 men aged
50–80 years completed the survey.
RESULTS
The prevalence of LUTS varied among the countries, ranging from 14% in
Singapore to 59% in the Philippines. Moderate to severe LUTS were reported
by 36% of men aged 50–59 years, 50% aged 60–69 years and 60% aged
70–79 years. About three-quarters of all respondents (72%) aged 50–80 years
were sexually active. Erectile dysfunction was reported by 63% of men in the
study, of whom 57% were bothered by their symptoms. Ejaculation disorders
were present in 68% of respondents (52% reported bothersomeness) and pain on
ejaculation was experienced by 19% of the men in the study (88% reported
bothersomeness). Sexual disorders increased with age and increasing severity
of their LUTS. Erectile and ejaculation problems were more common in
subjects with diabetes or hypertension; these two groups showed the same
relationship between LUTS severity and sexual disorders.
CONCLUSION
These results confirmed that sexual activity is common in
Asian men aged 50–80 years, even at an advanced age. They also confirmed the
correlation between LUTS and sexual dysfunction.
