Sexual risk and STDs are relatively high among injecting drug users (IDUs) in Vietnam. We sought to determine characteristics of sexually active IDUs and correlates of high-risk sexual practices among IDUs in Bac Ninh province in northern Vietnam.
We used data collected for a community-based cross-sectional pilot study to identify correlates of recent high-risk sex (>1 sex partner and inconsistent/no condom use in the past year). Factors associated with high-risk sex were identified using logistic regression.
Among 216 sexually active male IDUs, one third (n=72) had engaged in high-risk sex within the last year. IDUs who reported injecting with others more frequently, having someone else inject their drugs at last injection, sharing needles or sharing any injection equipment were more likely to have reported recent high-risk sex. Factors independently associated with high-risk sexual activity were not injecting oneself [AOR: 2.22; 95% CI (1.09-4.51)], and sharing needles in the past 12 months [AOR: 2.57; 95% CI (1.10-5.99)].
IDUs who inject socially and IDUs who share needles are likely to engage in high-risk sexual behaviours and may serve as an important bridge group for epidemic HIV transmission in Vietnam. In addition to messages regarding the dangers of sharing needles and other injection equipment, preventive interventions among newly initiated IDUs should also focus on reducing sexual risk.
在越南，注射吸毒者（IDU）中的性风险和性传播疾病（STD）发生率相对较高。我们试图确定越南北方北宁省性活跃的注射吸毒者的特征以及注射吸毒者中高危性行为的相关因素。
我们使用了一项基于社区的横断面试点研究收集的数据，以确定近期高危性行为（>1个性伴侣且在过去一年中使用避孕套不一致/未使用）的相关因素。使用逻辑回归确定与高危性行为相关的因素。
在216名性活跃的男性注射吸毒者中，三分之一（n = 72）在过去一年中曾有过高危性行为。报告更频繁与他人一起注射、上次注射时让他人给自己注射毒品、共用针头或共用任何注射设备的注射吸毒者更有可能报告近期有高危性行为。与高危性活动独立相关的因素是不自行注射[AOR： 2.22；95%置信区间（1.09 - 4.51）]，以及在过去12个月内共用针头[AOR：2.57；95%置信区间（1.10 - 5.99）]。
社交性注射的注射吸毒者和共用针头的注射吸毒者可能会从事高危性行为，并且可能成为越南艾滋病毒传播流行的重要桥梁人群。除了宣传共用针头和其他注射设备的危害外，对新开始注射吸毒的人群进行的预防干预还应侧重于降低性风险。
