| ObjectiveAcquired Immune Deficiency Syndrome, which is well known as AIDS, is a chronic infectious disease resulting from HIV infection. The mobility of population can increase the risk of HIV infection. Migrant workers are high-risk population of AIDS because of their mobility characteristics. In this study we took interventions to migrant workers in Zhengzhou in order to improve their HIV-related knowledge and reduce their fear and discrimination against this disease, and ultimately to change their unprotected behaviors and prevent the spread of HIV. Furthermore, based on this study we explored appropriate HIV intervention modes for migrant workers.MethodsStratified cluster sampling design was used. The sample consisted of 889 migrant workers randomly drawn from nine departments in Central Plains District of Zhengzhou City. Migrant workers were given HIV intervention and questionnaire survey. The intervention modes consisted of watching VCD, focused propaganda, comprehensive intervention (watching VCD and focused propaganda) and control. Data was built using Epidata 3.02 software. Data was analyzed by the ways of descriptive analysis, chi-square test, variance analysis and multiple correspondence analysis using SPSS 17.0 for windows.The significant level is 0.05.Results1. HIV-related knowledge, attitude and behaviors of migrant workers in ZhengzhouThe awareness rate of AIDS knowledge in migrant workers was 59.2%. Scores of HIV-related attitude were 59.55 points (percentile). The rate of condom use in sexual behaviors was 62.9%.2. Evaluation of HIV prevention intervention modelsUsing percentage scoring system, scores of HIV knowledge in watching VCD group, focused propaganda group, comprehensive intervention group and control group were 76.51±20.51,88.30±20.67,91.48±15.70,68.83±22.16 respectively. Migrant workers watching VCD had significantly higher mean scores for HIV knowledge than control group (F=166.069, P<0.001).Also people of focused propaganda group had significantly higher mean scores than control group (F= 16.589,P<0.001). There were not interaction effects on HIV knowledge of migrant workers between watching VCD and focused propaganda (F=2.847, P=0.092).Scores of HIV-related attitude in watching VCD group, focused propaganda group, comprehensive intervention group and control group were 65.23±15.67, 60.75±15.52,69.66±15.54,59.55±16.37 respectively. Migrant workers watching VCD had significantly higher mean scores for HIV-related attitude than control group (F=7.072, P=0.008).Also people of focused propaganda group had significantly higher mean scores than control group (F=47.417, P<0.001). There were not interaction effects on HIV-related attitude of migrant workers between watching VCD and focused propaganda (F=2.328, P=0.127)There was significant difference between focused propaganda group and control group on the intention of condom use. So the way of focused propaganda could improve the rate of condom use of migrant workers effectively.3. Multiple correspondence analysis of HIV-related knowledge, attitude and the intention of condom useThere were association between knowledge and attitude (χ2=141.04, P< 0.001), knowledge and the intention of condom use (χ2=58.64, P<0.001), attitude and the intention of condom use (χ2=36.64, P<0.001). Results of multiple correspondence analysis showed that there were association among knowledge classified as "poor", attitude classified as "poor" and" not using condoms in the future". Knowledge classified as "good" was associated with attitude classified as "good". Correlation existed in knowledge classified as "excellent"and attitude classified as "excellent".Conclusions1. Migrant workers in Zhengzhou had poor AIDS knowledge as a whole. And the status of attitude and practice about AIDS among them in Zhengzhou is poor.2. There are association among HIV-related knowledge, attitude and the intention of condom use among migrant workers. A good level of knowledge promotes a positive level of attitude toward HIV and safe sex behaviors.3. In this study it is found that two HIV intervention modes, watching VCD and focused propaganda conduct effectively among migrant workers.
