| Objective To understand basic status of knowledge, attitude and practice related to AIDS in different kinds of schools in Shandong provincial students, and establish scientific health education models which adapt to different kinds of schools.MethodsSampling-method and sample-size: Random, multistage, stratification, Chester sampling method was taken in 28 schools including 4 universities, 4 colleges, 4 urban senior high schools, 4 rural senior high schools, 4 technical schools, 4 urban junior high schools, and 4 rural junior high schools. 5870 students were investigated in baseline survey and 5771 students in effect survey.Survey method: To understand students' knowledge, attitude, practice and demand, status of school health education related to AIDS with KAP questionnaires were gathered and interviewed.Intervention method: Teachers, school doctors and leaders from 28 experimental schools were trained to provide 4 different kinds of materials for students, and materials were delivered with 3 models: The first one was optional, there was no request and no guidance. The second one was optional, there was request but noguidance. The third one was organized, centralized and directed. To give a health education course in experimental schools with an appointed teaching materials. There were 3 teaching models: the 1st model was to give a course in a small scale to 40 to 60 students. The 2nd model was to have a large-scale course in 4 to 6 classes. The 3rd was teaching on the closed-circuit television.ResultsBaseline survey: The rates of AIDS knowledge were 56.4%, 48.0%, 64.8%, 57.9%, 53.3%, 66.2%, 68.8% in urban junior high schools, rural junior high schools, urban senior high schools, rural senior high schools, technical schools, colleges and universities, respectively. The lowest were those of rural schools and technical schools. The rates of AIDS knowledge on the route of transmission, non- transmission route, preventive methods, non- preventive methods and basic conception of were 78.0%, 55.3%, 71.5%, 34.8%, 56.1%, respectively. Many students discriminated seriously against HIV infected person and AIDS patients. Students have a strong demand to the knowledge related to AIDS. Most experimental schools didn't carry out health education on AIDS.After-intervention effect survey: The rates of AIDS knowledge were 85.4%, 68.6%, 82.0%, 73.8%, 78.5%, 80.1%, 79.0% respectively in 7 kinds of schools and raised by 29.0%, 20.6%, 17.2%, 15.9%, 27.2%, 13.9%, 10.2%. The best intervention effect was obtained in urban junior high schools and technical schools. The worst intervention effect was in universities. The right attitude to HIV infected person and patients with AIDS were greatly higher than that in baseline survey. The intervention period was 3 months.The effect evaluation of different models: the best model in delivering of materials was the 3rd model. Many students receive "prescription" and "picture poster" on AIDS. The rate of receiving materials was greatly different in different schools. The highest was that of urban junior schools, the lowest was that of universities. The rate of training course was higher in middle schools than that in universities, and it was higher in urban schools than that in rural schools. In 3 teaching models, the 1st one was best. The effect was better in small classes than that in bigclasses, on-the-spot teaching effect was better than that by TV.Conclusion The rates of AIDS knowledge were lower in our schools. So we must carry out health education on AIDS in all schools, especially in rural schools, technical schools and universities. More attention should be paid on non- preventive methods, non-transmission route and basic conception. The best model in materials-delivering was the 3rd model—an organized, centralized and directed model. The best training model was the 1st one- a small-class course to 40-60 students. The key of success of intervention was not many materials or many teachinging styles, et al but the models to deliver materials and the models to teach.
