To estimate the prevalence of HIV testing and examine factors associated with recent HIV testing among people who use drugs (PWUD) in Cambodia.
Cross-sectional study.
Twelve major provinces with a high burden of HIV and drug use in Cambodia.
This study included 1677 PWUD recruited using a peer-based social network recruitment method. Participants' selection criteria included being at least 18 years old and using any illicit drugs via any administration routes in the past 12 months.
Recent HIV testing, defined as having an HIV test in the past 6 months.
The median age of the participants was 28 (IQR 22-34) years, and 56.6% were men. The prevalence of lifetime and recent HIV testing was 70.7% and 42.9%, respectively. After adjustment in multivariable logistic regression analysis, recent HIV testing remained positively associated with being female (adjusted OR (AOR) 1.55, 95% CI 1.18 to 2.04) or third gender identity (AOR 2.06, 95% CI 1.11 to 3.80), having ever been to a drug rehabilitation centre (AOR 1.60, 95% CI 1.13 to 2.29), having used any HIV services in the past 6 months (AOR 7.37, 95% CI 5.61 to 9.69), having received HIV education in the past 3 months (AOR 3.40, 95% CI 2.63 to 4.40) and having self-perception of higher HIV risk (AOR 1.81, 95% CI 1.19 to 2.73).
Recent HIV test uptake among PWUD in Cambodia was suboptimal. This study highlights the roles of outreach HIV education and services in promoting regular HIV testing among PWUD. Strengthening the coordinated effort of government agencies and local civil society organisations to prioritise expanding community-based peer-driven interventions to reach out to this hidden population is warranted.
估计柬埔寨吸毒者（PWUD）中 HIV 检测的流行率，并探讨与最近 HIV 检测相关的因素。
横断面研究。
柬埔寨 12 个 HIV 和吸毒负担较重的主要省份。
本研究纳入了 1677 名采用同伴为基础的社交网络招募方法招募的 PWUD。参与者的入选标准包括年龄至少 18 岁，且在过去 12 个月内曾通过任何给药途径使用任何非法药物。
最近的 HIV 检测，定义为过去 6 个月内进行的 HIV 检测。
参与者的中位年龄为 28（IQR 22-34）岁，56.6%为男性。终身和最近 HIV 检测的流行率分别为 70.7%和 42.9%。多变量 logistic 回归分析调整后，最近的 HIV 检测仍与女性（调整后的比值比（aOR）1.55，95%置信区间（CI）1.18 至 2.04）或第三性别认同（aOR 2.06，95%CI 1.11 至 3.80）、曾去过戒毒中心（aOR 1.60，95%CI 1.13 至 2.29）、过去 6 个月内使用过任何 HIV 服务（aOR 7.37，95%CI 5.61 至 9.69）、过去 3 个月内接受过 HIV 教育（aOR 3.40，95%CI 2.63 至 4.40）和自我感知 HIV 风险较高（aOR 1.81，95%CI 1.19 至 2.73）相关。
柬埔寨吸毒者最近 HIV 检测率不理想。本研究强调了外展 HIV 教育和服务在促进吸毒者定期进行 HIV 检测方面的作用。值得加强政府机构和当地民间社会组织的协调努力，优先扩大以社区为基础的同伴驱动干预措施，以接触这一隐藏人群。
