Data are limited about the role of initiators in the transition to injection drug use. We examined the prevalence and predictors of giving someone their first injection using baseline data from a study involving 98 injection drug users (IDUs) in Toronto, Canada. Participants were recruited in 2011 using respondent-driven sampling. Findings revealed that 27.4 % (95 % CI 14.7-42.2) of IDUs had ever given anyone their first injection. In the logistic regression analysis, being unemployed and having ever spoken positively about injecting to a non-injector were associated with giving someone their first injection. Furthermore, the odds of initiating non-IDUs increased with the number of years that IDUs had been injecting. Our results provide support for interventions that aim to reduce the initiation of non-IDUs; however, further research is needed to shed light on the link between unemployment and initiation of non-injectors.
关于启动者在向注射吸毒过渡中的作用，相关数据有限。我们使用加拿大多伦多一项涉及 98 名注射吸毒者（IDU）的研究的基线数据，调查了给某人首次注射的流行情况和预测因素。研究对象于 2011 年通过应答者驱动抽样招募。结果显示，27.4%（95%置信区间 14.7-42.2）的 IDU 曾给任何人注射过第一针。在逻辑回归分析中，失业和曾向非注射者积极谈论过注射与给某人首次注射有关。此外，IDU 注射的年限越多，启动非 IDU 的可能性就越大。我们的研究结果为旨在减少非 IDU 启动的干预措施提供了支持；但是，需要进一步的研究来阐明失业与非注射者启动之间的联系。
