| Objective Understand the HIV and syphilis infection of drug users in the community of Ma'anshan and analyze their behavior characteristics. Basing on the baseline study of HIV and syphilis infection, related knowledge, attitude, behavior and impact factor of community drug users, depending on the platform of community and family network, explore the strategy for the AIDS behavior intervention in community drug users.Method The investigation scene was chosen in Yushan Community and Huashan Community of Ma'anshan, Anhui. With snowball sampling, we carried out a cross-sectional study on the subjects utilizing the unifiedly designed questionnaire. Conduct the AIDS intervention to the drug users in those two communities. A cross-sectional study with the same questionnaire was done after the intervention, which was comparatively analyzed with the baseline investigation results. Descriptive analysis,χ2 test, t test and regression analysis were undergone with the statistics software SPSS.Results There were 385 community drug users who were investigated before the intervention, with the HIV positive infection rate of 0.78% and syphilis positive infection rate of 6.75%. All 3 HIV positive infectors had used a sharing syringe, 2 of whom had unmarried sexual behavior, and the difference among the drug taking forms was statistically meaningful (χ2=4.286, P=0.038); syphilis positive subjects took up 26 of them, whose ages concentrated in 31~40. There were 189 community drug users who were investigated after the intervention, with none HIV positive infector and 14 syphilis positive infectors, and syphilis positive infection rate was 7.40%. There were no statistically significance between HIV positive infection rate and syphilis positive infection rate before and after intervention. The correlation factor regression analysis of the drug users'voluntary HIV test indicated that the impact factors contained sharing syringes with others, voluntary rehabilitation in drug rehabilitation center, participating in the methadone maintenance treatment, receiving the AIDS counseling, using condoms in the latest sex and having sex with a temporary partner in the latest year. The rate of the intravenous injection of drugs showed a statistically meaningful difference before and after the intervention (χ2=27.356, P<0.001); the rate of intravenous injection of drugs in the latest month showed a statistically meaningful difference before and after the intervention (χ2=22.715, P<0.001); the rate of syringe sharing with others in the latest month showed a statistically meaningful difference before and after the intervention (χ2=36.848, P<0.001). The condom using rate of the latest sex before and after the intervention showed a statistically meaningful difference (χ2=8.816, P=0.003); the condom using rate of the latest sex with a temporary partner before and after the intervention showed a statistically meaningful difference (χ2=5.026, P=0.025).Conclusion The most important factor was the infection through sharing syringes that caused the HIV transmission in the intravenous drug users, while another dangerous one was the high risky sex without protecting. There was a high syringe sharing rate among the drug users in the community in Ma'anshan City, while the condom using rate of the unprotected high risky sex was low. It was suggested that they should develop HIV and sexually transmitted disease (STD) counseling and test in the community. Propaganda and education were the most effective way to prevent HIV/STD from transmitting in the crowd, in addition to the pointed behavior intervention, to control the transmission of epidemic disease such as HIV from the high risky group to the common crowd. |
