In this paper, we explore the understudied phenomenon of "low-frequency" heroin injection in a sample of street-recruited heroin injectors not in drug treatment. We conducted a cross-sectional study of 2,410 active injection drug users (IDUs) recruited in San Francisco, California from 2000 to 2005. We compare the sociodemographic characteristics and injection risk behaviors of low-frequency heroin injectors (low-FHI; one to 10 self-reported heroin injections in the past 30 days) to high-frequency heroin injectors (high-FHI; 30 or more self-reported heroin injections in the past 30 days). Fifteen percent of the sample met criteria for low-FHI. African American race, men who have sex with men (MSM) behavior, and injection and noninjection methamphetamine use were independently associated with low-FHI. Compared to high-FHI, low-FHI were less likely to report syringe sharing and nonfatal heroin overdose. A small but significant proportion of heroin injectors inject heroin 10 or less times per month. Additional research is needed to qualitatively examine low-frequency heroin injection and its relationship to drug use trajectories.
在这项研究中，我们探索了一个在未经药物治疗的街头招募的海洛因注射者样本中研究不足的现象，即“低频”海洛因注射。我们对 2000 年至 2005 年间在加利福尼亚州旧金山招募的 2410 名活跃的注射吸毒者（IDU）进行了横断面研究。我们将低频海洛因注射者（低 FHI；过去 30 天内自我报告的海洛因注射次数为 1 至 10 次）与高频海洛因注射者（高 FHI；过去 30 天内自我报告的海洛因注射次数为 30 次或更多）的社会人口统计学特征和注射风险行为进行了比较。样本中有 15%的人符合低 FHI 的标准。非裔美国人种族、男男性行为者（MSM）行为以及注射和非注射冰毒使用与低 FHI 独立相关。与高 FHI 相比，低 FHI 报告共用注射器和非致命性海洛因过量的可能性较小。一小部分但数量可观的海洛因注射者每月注射海洛因 10 次或更少。需要进行更多的定性研究来探讨低频海洛因注射及其与药物使用轨迹的关系。
