Abstract
OBJECTIVE: To understand the status on AIDS awareness, AIDS-related behaviors, risk factors on HIV infection status among 15 – 90 years or older men at the sexually transmitted disease clinics.

METHODS: Data from the 2009 and 2010 national sentinel surveillance system, regarding men attending sexually transmitted disease clinics was collected from Guangdong, Guangxi, Henan, Sichuan, Yunnan and Jiangxi provinces, where the AIDS epidemic among 15 – 90 years or older population was serious. Data was uploaded to National Center for AIDS/STD Control and Prevention (NCAIDS) through the comprehensive AIDS control and prevention information system. Data was then analyzed by SPSS 18.0.

RESULTS: A total of 64 003 pieces of data were collected. Among them, 8783 (13.7%) were related to men at ≥ 50 years or older, and to men 15 – 49 years older were 55 220. The rates on the awareness of AIDS knowledge were from 69.6% vs. 80.1%, on frequently having had commercial sexual contacts in the last three months were between 34.1% vs. 36.6%, on having had casual sexual contact in the last three months were 18.7% vs. 28.4%, on having had homosexual anal intercourse as 0.7% vs. 1.4%. The rates of taking HIV antibody testing in the last year (14.3% vs. 17.1%) among this population were all significantly lower than the rate among the 15 to 49 years age group. However, the HIV-positive rate among the older age group (fifty years of age or older) was significantly higher than the rate among 15 to 49 year age group (1.1% vs. 0.7%). Regard the fifty years of age or older men. Data from the multivariate logistic regression analysis demonstrated that factors as: having regular partner (OR = 0.588, P = 0.034), having homosexual anal intercourse (OR = 5.226, P = 0.006) were associated with positivities of HIV antibody.

CONCLUSION: High-risk sexual behaviors, including homosexual anal intercourse were the major risk factors for men at ≥ 50 years or older age, related to the infection of HIV.
