Methods A cross sectional survey was conducted among 800 MSM by face to face interviewing and blood samples were taken to test HIV / syphilis. Result The rate of knowledge about HIV was 95.5%, HIV infection rate was 6.75%, Syphilis infection rate was 4.5%, HIV (+) rate among people who have anal sex without condom or sometimes with condom in late 6 months was higher than those who have no anal sex and every sex with condom. Condom usage rate of people who had AIDS prevention consulting was higher than those who had no consulting; while the HIV (+) rate was opposite. The HIV (+) rate among syphilis (+) people was higher than syphilis (-) people. Conclusion the ADIS prevention knowledge of MSM was good but the condom usage rate was low, indicating that the knowledge and behavior was separated. Consulting could improve the condom usage rate and reduce the HIV infection. Thus, entire and effective AIDS prevention consulting services, condom usage popularization and patient screening are significant methods for preventing and controlling of HIV infection and transmission.

Table 2010-2011 Xi'an MSM the crowd blood test results


800 survey of MSM HIV infection rate of 6.75%, syphilis 4.5%, the flat four cities of Beijing, Chengdu, Zhengzhou, Harbin average HIV infection rate of 6.7%

 [1] The survey test results showed that, among the 800 blood test, AIDS awareness, especially the route of transmission of AIDS awareness all in more than 90%, but the sex survey, 95.75% of the MSM last six months with the same sex anal sex, which can each use condoms only half (396/766, anal sex by HIV positive rate was significantly higher than anal sex, never used or sometimes used condoms HIV The positive rate was significantly higher than the condom every time, indicating the existence of separation of MSM AIDS awareness and behavior

[2]therefore not only by the simple means of propaganda and the MSM crowd behavior intervention, should be strengthened in this population awareness of condom use, increase the intensity of behavioral interventions, conducting various forms of intervention to improve the rate of condom use.

The survey also showed that the people received AIDS Prevention advisory services, in the last six months with the same sex, anal sex, condom use among the HIV infection rate is also significantly lower than that did not receive the crowd, to undertake a comprehensive and effective AIDS prevention outreach and counseling to improve the coverage of prevention of AIDS-related services, can greatly reduce the risk of infection and the spread of AIDS in this population.

The test results show that the higher the proportion of HIV-positive syphilis positive. STD patients is not early detection and effective treatment, will increase the chance of transmission of HIV, the risk would be greater. Studies show that STD patients, especially those associated with genital ulcers, such as syphilis, genital herpes, chancroid, etc., the risk of transmission of HIV can be increased by 2-10 times. different from other sexually transmitted diseases and AIDS, can be completely cured, effective and comprehensive prevention and treatment of sexually transmitted diseases can be a significant reduction of HIV carrier volume, thereby slowing the spread of AIDS and pop. prompt us to increase the intensity of screening for HIV STD attenders, help to maximize the early detection of infection.
