High Risk Factor Of Behaior For HIV/AIDS Preverlence And Evaluation For Intervention In Mianyang, Guangyuan And Leshan Prefecture Site Of Sichuan(2002-2003)

Objectives: To find out the status and trends of high-risk behavior related to AIDS epidemic in target groups of population and to compare behavior from different sites according to the behavir research in high risk pobulation in a continue information collection system. These behavior information can help us to find out AIDS/STD epidemic situation and trend by combined with the biological data of the pathogens and evaluate the impact of different HIV/STD prevention and control activities.This research can provide the information base for government policy-makers in developing and improving HIV/STD prevention and control strategies and set up the measures for intervention of HIV/STD epidemic.Methods: We have conducted the comprehensive proposal,questionare and behavior surveillance guildline according to behavior surveillance method of UNAIDS,WHO and FHI and combining situation of pilot sites.Behavior surveillance has been implemented in Mianyang,Guangyuan and Leshan prefecture sites of Sichuan form 2002 to 2003.Intervention activeties has also been developed in three sites.AII the activities in pilot sites has conducted according to the proposal and has quality control.Results:1.Three target populatons have improved remarkblely about the knowledge for HIV/AIDS through health education but different target groups still lack of comprehensive knowledge such as misquito knowledge point(average percentage is 40%). Different sites havedifferent situation and level.2.High risk behavior had been changed by helding intervention and it need been developed and strenthed.Behavior research data showed there are nearly 50% CSW expose herself to unprotect sex behavior and there existing networking of high risk behavior perbasion.Peer education and needle exchange activities has low effect.The needle exchange percentage has rised to 76.2% form ? and the percentage of sharing drug assistant things has rised up.The percentage of using new needles has down and the HIV transmiting approach by sex has been developed.The long term drivers general have high risk behavior and the percentage of condom use in three sex partners in 12 months.The percentage of condom use with CSW is 31.6% and other two sex partners are lower.3.The risk cognizing by three target groups has appreciably developed through VCT data but the intervention coverage is still small by collecting information in two years.Conclusions: Main findings through high risk factor of behaior for HIV/AIDS preverlence and evaluation for intervention in Mianyang, Guangyuan and Leshan Prefecture Site of Sichuan(2002-2003) as follows:1. Health education focus on key points must be strengthened and modified health education strategies and methods by different situation.IEC materals must be done focus on knowledge weakness and acceptable side.2. There is some effect by intervention activities for CSW and the effect is not remarkable related to high fluid in CSW.The intervention plan must be paid more attention to the changes in high risk groups.3. Data has showed there is no effect in IDU and the behavior ofneedle sharing has rised up.lDU with HIV/AIDS can easily transmit virus to other person induing general population with high risk behavior such as needle sharing,more sex partners and low condom use. This result suggested us that IDU will be the key intervention group in planning especially IDU with commercial sex.4. We can not ignore the risk of bridge population such long term driver and develop their knowledge and protect themselves by safe behavior.5. The quality of STD service must be improved because the percentage of need to right medicine in high risk groups is low. We can provide high quality STD service and develop the skills of medical staffs. VCT is needed in our intervention planning.This survey has provided more information about changes in high risk behavior and can be reference materials to policy making in Mianyang, Guangyuan and Leshan. There is behavior surveillance modle through research work.
