The awareness rate of AIDS prevention knowledge among them was 70.52%, and it’s significantly rising year by year(χ2=75.68, P<0.001). The better educated, the younger, the fewer pregnancies and the less number of birth were all the positive influence factors of the knowledge awareness rate of AIDS prevention. Conclusions HIV, syphilis and HCV infection rate among pregnant women in Chengdu are all lower than the average level in China, but the awareness rate of AIDS prevention knowledge in this group is still needed to be improved.
