Totally, 3. 7% were HIV-infected, of whom 64. 3% were newly identified after detained in the centers. Logistic regression analysis indicated that the males of 20 years old or above, ethnic minors, illiteracy and foreign had high prevalence of HIV infection, and the risk of HIV infection was much higher among injection drug users （OR =11.25, 95%CI： 9. 36-13.53） and those having sex with non-regular sex partners （oR=2.46,95%CI：2.03-2. 97）. Among the females, the risk factors were 20 years old or above, ethnic minors except fingpo and nonlocal registered residence. High risk of HIV infection was higher in injection drug users （OR = 11.17, 95 % CI： 6. 73-18.54） and those having sex with non-regular partners （OR=2.54, 95% CI： 1.40-3.97）.
