People who use drugs (PWUD) remain at high risk for acquiring human immunodeficiency virus (HIV), both from injection and from sexual risk-taking. In 2016, 9% of 39,782 new HIV diagnoses occurred among people who inject drugs in the United States. Reaching PWUD with accurate information about and motivation for initiating pre-exposure prophylaxis (PrEP) remains challenging and remains the first crucial step in the knowledge-attitude-behavior change continuum. This study seeks to contribute to closing this information gap by examining the HIV information-seeking behaviors among PWUD who are not on PrEP, so as to identify potential strategies to increase adoption of HIV prevention such as PrEP as part of overall health and related to risk-taking behaviors. A cross-sectional survey was conducted in 2016 among HIV-negative PWUD (n = 400), 57.3% of whom reported injecting at least once in a week, chronically maintained on methadone treatment (MMT) at a large addiction treatment program. The study found that the number of hours spent online by people who use drugs was comparable to the general population. Awareness about PrEP and the seeking of HIV-related information was low in this population. Looking for sex partners online, perception of risk, having multiple partners were associated with seeking HIV information. Although using injection drugs was related to high perception of risk of acquiring HIV, it was not associated with seeking HIV information online. It is imperative to further understand the online HIV information seeking behavior of this population and provide targeted information in order to increase awareness and knowledge about HIV-related risk and methods of prevention, including information about PrEP.
吸毒者感染人类免疫缺陷病毒（HIV）的风险仍然很高，无论是通过注射还是通过性行为冒险。2016年，在美国39782例新的HIV诊断病例中，9%发生在注射吸毒者中。向吸毒者提供关于启动暴露前预防（PrEP）的准确信息并激发其动机仍然具有挑战性，并且仍然是知识-态度-行为改变连续体中的关键第一步。本研究旨在通过调查未接受PrEP的吸毒者的HIV信息寻求行为来缩小这一信息差距，从而确定潜在策略以增加对HIV预防措施（如PrEP）的采用，将其作为整体健康的一部分并与冒险行为相关联。2016年对400名HIV阴性吸毒者进行了一项横断面调查，其中57.3%的人报告每周至少注射一次，在一个大型戒毒治疗项目中接受美沙酮维持治疗（MMT）。研究发现，吸毒者上网的时长与普通人群相当。该人群对PrEP的知晓率以及对HIV相关信息的寻求率较低。在网上寻找性伴侣、对风险的认知、拥有多个性伴侣与寻求HIV信息有关。虽然注射吸毒与对感染HIV高风险的认知有关，但与在网上寻求HIV信息无关。必须进一步了解该人群的在线HIV信息寻求行为，并提供有针对性的信息，以提高对HIV相关风险和预防方法的认识和了解，包括关于PrEP的信息。
