英文摘要：

Objective To learn about the present situation of discrimination against people living with HIV/AIDS and its influence factors among high-risk populations, such as female sex workers（FSW）, patients with methadone maintenance treatment and men who have sex with men（MSM） in Ma＇anshan city. Methods FSW, MSM and patients with methadone maintenance treatment were interviewed directly by the interviewers. Measurement data were expressed as mean zk standard deviation. Qualitative data were expressed by ratio or proportion,and compared by Х^2 test or Fisher exact test. Logistic regression analysis was used for the related factors. Results A total of 450 questionnaires was valid. The suspect influence factors on attitude were analyzed by multiple logistic regression. When dependent variable was set as ＂Whether contact with HIV infection/AIDS patient＂ or ＂Whether allow HIV infection/AIDS patient to work＂, two factors were included into regression model. Drug addicts, MSM and people whose HIV/AIDS knowledge score lower than 6 tended to avoid keeping contact with HIV infection and AIDS patient, and also rejected to allow them working. Conclusions MSM and drug addicts are more prone to discriminate against HIV/AIDS than FSW. People whose HIV/AIDS knowledge score lower than 6 are more like to have a prejudice against HIV injection and AIDS patients.
