[Study on the effect of intervention about acquired immunodeficiency syndrome among men who have sex with men].
OBJECTIVE
To study the outcomes of AIDS intervention programs and to provide scientific evidence for developing pertinent strategy on intervention among men who have sex with men (MSM).


METHODS
MSM were recruited through snowballing and investigated by face to face interview in 2006 and 2007 respectively. SPSS 12.0 was used to compare the change of cognition about AIDS, sexual behavior, prevalence rates of HIV and Syphilis before and after the intervention program among the population under study.


RESULTS
The cognition about AIDS among MSM was obviously improved after the intervention with the rate increased from 74.3% to 82.4% (P = 0.01). The rate of last time condom use among MSM increased from 56.4% to 65.5% (P = 0.00). The rate of consistent condom use during six months among MSM increased from 31.8% to 41.9% (P = 0.00). The rates of both condom use during commercial sex with men and with women did not change much among MSM. The prevalence rates of HIV in 2006 and 2007 were 10.4% and 10.8% and of syphilis in 2006 and 2007 were 9.3% and 7.3% respectively which were not significantly different between before and after the intervention.


CONCLUSIONS
The cognition about AIDS among MSM was improved obviously. However, the rate of consistent condom use was still low, reflecting the segregation phenomenon between their behavior and cognition. All our findings implied that it was crucial to carry out AIDS prevention and control programs.
