目的：在墨西哥以公共卫生为导向的毒品政策改革的背景下，我们评估了蒂华纳注射吸毒者（PWID）中警察遭遇的空间分布，确定了这些遭遇与成瘾治疗中心位置之间的关系，并探讨了警察遭遇与治疗机会之间的关系。设计使用来自蒂华纳社区招募的PWID队列的前瞻性空间数据和来自蒂华纳市警察局的官方地理逮捕数据进行地理加权回归（GWR）和逻辑回归分析。SettingTijuana,墨西哥。在2011年1月至12月期间招募的前瞻性研究中，共有608名参与者（中位年龄37岁，28.4%为女性）。测量方法我们比较了警察遭遇的平均距离和随机分布的事件集到治疗中心。GWR对警察互动与治疗中心之间的空间关系进行了建模。Logistic回归分析用于调查与报告警察互动相关的因素。在研究期间，27.5%的警察遭遇发生在距治疗中心500米的范围内。GWR模型显示就诊与治疗中心之间存在空间相关性（globalR2= 0.53）。报告成瘾治疗需求与报告逮捕和警察袭击相关[调整后优势比= 2.74,95%可信区间(CI) = 1.25-6.02，P= 0.012]。一项地理空间分析表明，在墨西哥，如果注射吸毒者认为自己需要戒毒治疗，他们成为警察暴力受害者的风险更大，而且他们与警察的互动似乎在治疗中心附近更频繁。
AimsIn the context of a public health‐oriented drug policy reform in Mexico, we assessed the spatial distribution of police encounters among people who inject drugs (PWID) in Tijuana, determined the association between these encounters and the location of addiction treatment centers and explored the association between police encounters and treatment access.DesignGeographically weighted regression (GWR) and logistic regression analysis using prospective spatial data from a community‐recruited cohort of PWID in Tijuana and official geographical arrest data from the Tijuana Municipal Police Department.SettingTijuana, Mexico.ParticipantsA total of 608 participants (median age 37; 28.4% female) in the prospectiveProyecto El Cuetecohort study recruited between January and December 2011.MeasurementsWe compared the mean distance of police encounters and a randomly distributed set of events to treatment centers. GWR was undertaken to model the spatial relationship between police interactions and treatment centers. Logistic regression analysis was used to investigate factors associated with reporting police interactions.FindingsDuring the study period, 27.5% of police encounters occurred within 500 m of treatment centers. The GWR model suggested spatial correlation between encounters and treatment centers (globalR2= 0.53). Reporting a need for addiction treatment was associated with reporting arrest and police assault [adjusted odds ratio = 2.74, 95% confidence interval (CI) = 1.25–6.02,P= 0.012].ConclusionsA geospatial analysis suggests that, in Mexico, people who inject drugs are at greater risk of being a victim of police violence if they consider themselves in need of addiction treatment, and their interactions with police appear to be more frequent around treatment centers.
