| Background: Since the first patient about HIV/AIDS was detected in 1981, the number of HIV infectors has been sharply rising. HIV infectors have been discovered in almost all countries in the global. The sum of HIV infectors in our country had reached 840 thousand from 1985 to the September, 2004. Freak-out via mainline has been the main route of transmission in our country, but the ratio of sex transmission is promptly rising. The druggers and the service industries attendants who hold high mobility and are on the age of sex activity are crucial population of preventing and controlling AIDS in our country. Because valid vaccine and therapy method about AIDS are short of, changing hazard behavior that is related with AIDS through health education is the only valid method of controlling AIDS spread.Objective: 1. To know the effect and insufficiency of previous health education and to offer the evidence of farther health education, the research about AIDS' knowledge, attitude and behavior among the service industries attendants and the druggers are carried out. 2. To offer theory evidence for designing valid health education models through evaluating the effect of health education among the service industries attendants. 3. To find more scientific new evaluation method of aiming at KAP health education.Methods: 1. Objects were composed of 655 the service industries attendants who were selected through stratified and cluster sampling and 368 druggers in a location of abstaining compulsively from drug. Questionnaires were filled out by them, and were analyzed in description. 2. Health education was carried out among the service industries attendants. Two studies were respectively carried out after health education was over one week later and six month later. 3. The data were analyzed with x~2-test, t-test, F-test and multiple linear regression. 4. The integrated effect of health education was analyzed with analytical hierarchy process. 5. The relations of K, A, P were analyzed with the method of quadrant.Results: 1. Over 97% of objects heard of AIDS; 81.4% of service industries attendants and 72.3% of druggers knew the source of infection, but 34.4% of service industries attendants and 25.3% of druggers considered that those who had touched with HIVinfectors transmit HIV; 73.9%-89.6% of service industries attendants and 69.0%-93.2% of druggers knew routes of transmission about AIDS, but only 55.6% of service industries attendants and 53.5% of druggers completely knew three routes of transmission; The correct answer rate to a majority of no routes of transmission was over 90%, but the mistake rate was high whether HIV was spread through insects biting. 2. Only 50% of objects held commiserative or concerned attitude to AIDS patients or HIV infectors. The rate of agreeing inhabitation a same community with HIV infectors was low. The rate of considering that HIV infectors should be restricted was high. 3. Behaviors were bad except for donating blood, learning and spreading AIDS' knowledge, especially the druggers. About the question of using condoms, 83.7% of druggers held correct attitude but only 30.1% of them used them; the rate of them among service industries attendants was respectively 66.3% and 66.1%. 41.1% of service industries attendants and 34.5% of druggers showed the behavior of treating them in time after they had contacted venereal diseases. 4. A majority of druggers hit the pipe through injection and 43.2% of them shared injectors or pinheads with others. 76.6% of druggers had unmarried sex behavior and had the tendency of multi-partners, but the rate of using condoms was low. 5. 93.2% of druggers knew the transmission route of sharing injectors or pinheads with others, but 42.3% of them showed the behavior; 92.4% of druggers knew the transmission route of sex, but 76.2% of them had unmarried sex behavior. 6. The effect of health education was obvious among service industries attendants. The correct answer rate to HIV/AIDS knowledge, behavior and attitude showed significant improvement, and anticipant goal was reached. Synthetic indexes showed above 75% in three investigations according to analytical hierarchy process. Furthermore, Synthetic indexes after health education rose significantly. However, knowledge on different questions showed huge difference. The knowledge rate that insects stinging can not transmit HIV/AIDS was only 52.4%. Though the rate increased significantly after health education was carried one week later, that got back primary level (56.3%) after 6 months later. The result about AIDS' attitude was bad, and health education didn't show relevant function among these aspects. Especially, the correct attitude to AIDS patients or HIV infectors showed significant deficiency. The relationship between STD with AIDS was vague. Only 51.3% of objects knew that treatingSTD in time may prevent AIDS though health education was carried out. 7. The score of druggers' KAP was relation with the degree of accepting education and the use of condoms; that of service industries attendants was relation with the degree of accepting education, health education and occupations. 8. The relationship among knowing the transmission route of sex, the behavior and attitude of using condoms when unmarried sex behavior was appeared was analyzed with the method of quadrant. The result showed that 62.5% of druggers and 63.8% of service industries attendants were located in quadrant I . The relationship among knowing the no routes of transmission of everyday contact, behavior and attitude to AIDS patients was analyzed with the method of quadrant. The result showed that 70.7% of druggers and 78.8% of service industries attendants were located in quadrant I . The relationship among K, A and P was analyzed quantitatively with the method of quadrant. The result showed that all objects were located in quadrant 1 . 9. A majority of objectives had the wish of attaining the knowledge of AIDS. Sources on knowledge of HIV/AIDS were varied, and main sources were television and radio, newspaper and magazines. Central channels were main resources of television and radio, and local newspapers and magazines were main sources of that. Sources on knowledge accorded with the channels that people expected.Conclusion: 1. Objects had some awareness of HIV/AIDS. However, knowledge on different questions showed huge difference. 2. Improvement of people' behavior and attitude was not isochronous with the mastery of knowledge. 3. Health education was valid manner of increasing knowledge. Persistent health education must be emphasized. 4. Main sources of attaining AIDS' knowledge for people were television and radio, newspaper and magazines. 5. The method of quadrant and analytical hierarchy process were valid measures of evaluating the effect of KAP health education. The former may evaluate the relationship among K, A and P, and the latter may synthetically evaluate the effect of health education.
