Frequency of injection has been consistently found to be higher among Puerto Rican Injection drug users (IDUs) than among other groups of IDUs. Several explanations have been suggested, but an empirical explanation has yet to be presented. This study compares the frequency of injection of Puerto Rican IDUs in East Harlem, New York, with that of IDUs in Bayamon, Puerto Rico. Study subjects comprised 521 Puerto Rican IDUs from East Harlem and 303 IDUs from Bayamon. The mean frequency of injection among IDUs in East Harlem was 2.8, the corresponding mean in Bayamon was 5.4. Younger IDUs reported a higher number of daily injection episodes than older IDUs, and the IDU group in Bayamon was 5 years younger than the group in East Harlem. The drug use variables accounted for a greater portion of the between-city difference than the demographic and psychosocial variables. Use of noninjected drugs, as well as the use of prescribed methadone, were found to be associated with a lower number of daily injections. Conversely, injection of cocaine, injection of cocaine mixed with heroin ("speedball"), and injection of larger amounts of drug solution were found to be associated with a higher number of daily injections.
一直以来，波多黎各注射吸毒者（IDUs）的注射频率高于其他吸毒群体。人们提出了几种解释，但尚未有基于实证的解释。本研究比较了纽约东哈莱姆区波多黎各吸毒者与波多黎各巴亚蒙吸毒者的注射频率。研究对象包括521名来自东哈莱姆区的波多黎各吸毒者和303名来自巴亚蒙的吸毒者。东哈莱姆区吸毒者的平均注射频率为2.8次，巴亚蒙的相应平均值为5.4次。年轻吸毒者报告的每日注射次数多于年长吸毒者，且巴亚蒙的吸毒者群体比东哈莱姆区的群体年轻5岁。与人口统计学和心理社会变量相比，吸毒变量在城市间差异中所占比例更大。发现使用非注射类毒品以及使用处方美沙酮与每日注射次数较少有关。相反，注射可卡因、注射可卡因与海洛因混合的“速球”以及注射大量毒品溶液与每日注射次数较多有关。
