More than half of all AIDS cases among Puerto Ricans have been attributed to injection drug use. Predictors of injection drug use cessation were examined among Puerto Rican injection drug users (IDUs) in New York and Puerto Rico. Analysis of baseline and 6-month follow-up data from 670 IDUs in NY and 316 in PR showed that 47% NY and 20% in PR reported cessation of injection at follow-up (p < .001). In multivariate analyses, having been in drug treatment since baseline was the only significant predictor of cessation for both sites (NY: AOR = 1.80; PR: AOR = 3.10). Increasing availability of methadone maintenance treatment, especially in PR, was indicated.
波多黎各艾滋病例中超过一半被认为是注射吸毒所致。对纽约和波多黎各的波多黎各注射吸毒者（IDU）中注射吸毒行为停止的预测因素进行了研究。对纽约670名注射吸毒者和波多黎各316名注射吸毒者的基线数据及6个月随访数据的分析表明，随访时纽约47%的注射吸毒者和波多黎各20%的注射吸毒者报告停止了注射行为（p < 0.001）。在多变量分析中，自基线以来接受药物治疗是两个地区注射行为停止的唯一显著预测因素（纽约：调整后比值比[AOR]=1.80；波多黎各：AOR = 3.10）。研究表明，美沙酮维持治疗的可及性在增加，尤其是在波多黎各。
