title: [A survey on AIDS knowledge rate and sexual behavior among men who have sex with men population at sexually transmitted disease clinic].
abstract: OBJECTIVE
  To survey on men who have sex with men (MSM) population's sexual behaviors, condom-service condition, HIV related knowledge and other issues among MSM population at sexually transmitted disease (STD) clinics to understand the characteristics of behaviors and offer suggestions for effective health education and behavior intervention.
  
  
  METHODS
  From January to December, 2009, we used anonymous questionnaires which involved in their mastery of demographic characteristics, sexual behavior, condom-service condition, HIV related knowledge, and so one, to investigate 200 MSM at 3 STD clinics of comprehensive hospital.
  
  
  RESULTS
  The average age of informant was (26.7+/- 8.9) years and 121 individuals (62.6%) had confirmed with STD in recent one year. In the recent 6 months, the average number of homosexual partners was 9.2+/- 4.8 and 102 (52.8%) had heterosexual partners. In the sexual intercourse with homosexual, 123 individuals had anal intercourse (63.7 %) and 117 had oral intercourse (60.6%). In the sexual intercourse with heterosexual, 92 (90.2%) individuals had vaginal intercourse, 37 (36.2%) had anal intercourse, and 59 (57.8%) had oral sex behavior.There were a statistical difference between heterosexual and homosexual sex behaviors (P<0.01). The condom-using frequency had statistic difference in different sexual behaviors(χ²=188.396, P<0.001). There was no linear correlation between HIV related knowledge and condom-using condition in sexual behaviors except the heterosexual anal intercourse.
  
  
  CONCLUSIONS
  High AIDS knowledge mastery rate is found in our survey. The respondents get HIV/AIDS knowledge through various ways actively. There is no obvious relation between the mastery of HIV related knowledge and condom-using frequency. The ratio of non-protected sexual behaviors is high in heterosexuals. How to adopt effective methods for behavior intervention to MSM at STD clinic needs to be further studied.
