很少有研究调查艾滋病毒在中国年轻吸毒者中的性传播。本研究的目的是探讨性传播对注射吸毒者（IDUs）和非注射吸毒者（NIDUs）感染艾滋病毒的作用。采用应答者驱动抽样（RDS）方法，对云南省426名海洛因/阿片类药物滥用者进行调查。Logistic回归模型进行检查之间的相互关系，危险的性行为，吸毒方式和吸毒的做法。相当比例的NIDU和IDU报告从事危险性行为，包括：（1）多个性伴侣（NIDU的42%对IDU的37%）;（2）同时性伴侣（48%对46%）;（3）商业性伴侣（23%对24%）和NIDU性伴侣（14%对17%）。非注射吸毒者和注射吸毒者报告与非固定伴侣（48%对42%）和固定伴侣（24%对27%）使用避孕套的比例较低，并且最近有甲基苯丙胺使用史（21%对18%）。与注射吸毒者相比，非吸毒者报告的性伴侣中注射吸毒者较少，注射吸毒网络同伴较少，非吸毒网络同伴较多，艾滋病毒知识和自我感知的艾滋病毒风险水平较低。艾滋病毒流行病从高危群体向一般人群的蔓延可能是由吸毒者中的危险性行为造成的。减少注射吸毒者和非注射吸毒者之间的性传播是中国吸毒者艾滋病干预的下一个主要挑战。
Little research has investigated sexual transmissibility of HIV among young drug users in China. The objective of this study was to examine the role of sexual transmission on HIV infection among injection drug users (IDUs) and non-injection drug users (NIDUs). Respondent-driven sampling (RDS) was used to recruit 426 young heroin/opium drug users in Yunnan, China. Logistic regression modeling was performed to examine interrelationships among risky sexual behaviors, drug-use modes, and drug-use practices. Substantial proportions of NIDUs and IDUs reported engagement in risky sexual behaviors including: (1) multiple sexual partners (42% of NIDUs vs. 37% of IDUs); (2) concurrent sexual partnerships (48% vs. 46%); (3) commercial sex partners (23% vs. 24%) and sex partners who were NIDUs (14% vs. 17 %). Both NIDUs and IDUs reported low levels of condom use with non-regular partners (48% vs. 42%) and regular partner (24% vs. 27%), and having a history of recent methamphetamine use (21% vs. 18%). Compared to IDUs, NIDUs reported having had fewer sex partners who were IDUs, fewer IDU network peers, more NIDU network peers, and having lower levels of HIV knowledge and self-perceived HIV risk. Generalization of the HIV epidemic from high-risk groups to the general population may be driven by risky sexual behavior among drug users. Reducing sexual transmission of HIV among both IDUs and NIDUs is the next major challenge for HIV intervention among drug users in China.
