Objective To investigate the H1V/AIDS- related knowledge, drug addictive behavxors and sexual behavior with spouses or regular partners among male HIV - positive drug users in Guangxi, and to provide the scientific evidences for strategy planning of HIV/AIDS prevention and better control of the transmission by injecting drug use or sexual behaviors. Methods Face to face questionnaire survey was conducted among male HIV- positive drug users with spouses or permanent sexual partners in the study area. The information of social demographic features, awareness of HIV/AIDS- related knowledge, drug abuse and sexual behavior were collected. Serological assay was used to detect the infection status of syphilis and genital her- pes simplex virus （HSV）. Meanwhile, the corresponding consultation and referral services were provided for the drug users. Results Totally, 382 subjects participated in this survey. Their average age was （36.5 ＋ 6.5） years. Most of them （91.6%） had an education level of elementary school and middle school. The awareness rate of HIV/AIDS- related knowledge was 95.8%. 3.4% had circumcision. The average age of drug use for the first time was （23.1 - 6.0） years. 98.4% had ever inject- ed drugs, among whom 93.1% shared needles. 62.5% injected drugs for over 10 years, and 51.6% were receving methadone treatment. 82.5 % told their HIV- positive status to their wives/partners. 271 （70.9 % ） knew their wives/partners＇ HIV status and 61.3 % of their wives/partners were HIV- positive （166/271）. The monthly frequency of sexual intercourse and the rate of non- use condom decreased after being told the HIV- positive status of their wives/partners （P 〈 0.01 ）. The infection rates of syphilis and HSV - 2 were 6.3 % and 52.8 %, respectively. Conclusions Surveillance and behavior interventions on drug use- rs should be strengthened. It is necessary to detect HIV infected population and inform them their test results as early as possible, to implement effective prevention and control approaches so as to reduce high- risk behaviors and better control the transmission by injecting drug use and sexual behavior.
