Although the dramatic rise of methamphetamine use in the general population has been well-documented, little is known about methamphetamine use in the homeless population. This study examines self-reported methamphetamine use and its correlates among a sample of 664 urban homeless adults in Los Angeles. Over one-quarter of the overall sample, and 60% of whites, disclosed lifetime methamphetamine use. Less than 10% of African-Americans reported ever using methamphetamine. Approximately one-tenth of respondents reported current methamphetamine use; almost 90% of current users shared straws to snort methamphetamine and half used it daily. Logistic regression analysis in younger (18-39) and older (40+) respondents revealed that white ethnicity, polydrug use and binge drinking were independently associated with lifetime methamphetamine use, regardless of age. Injection drug use (IDU) was also an important correlate of methamphetamine use for older African-Americans. IDU was not important for the younger group. Findings suggest that there is need for greater surveillance of methamphetamine use among homeless whites and Hispanics, and methamphetamine-use prevention and reduction targeted to younger, polydrug-using, alcohol-binging homeless adults.
虽然普通人群中甲基苯丙胺使用量的急剧上升已有充分记录,但对于无家可归者群体中甲基苯丙胺的使用情况却知之甚少。本研究调查了洛杉矶664名城市无家可归成年人样本中自我报告的甲基苯丙胺使用情况及其相关因素。在整个样本中,超过四分之一的人以及60%的白人披露有过甲基苯丙胺使用经历。不到10%的非裔美国人报告曾使用过甲基苯丙胺。约十分之一的受访者报告目前正在使用甲基苯丙胺;近90%的当前使用者共用吸管吸食甲基苯丙胺,一半人每天使用。对年龄较轻(18 - 39岁)和年龄较大(40岁及以上)的受访者进行的逻辑回归分析显示,无论年龄大小,白人种族、多种药物使用和暴饮与终生甲基苯丙胺使用独立相关。注射吸毒也是老年非裔美国人甲基苯丙胺使用的一个重要相关因素。注射吸毒对年轻群体并不重要。研究结果表明,需要加强对无家可归的白人和西班牙裔中甲基苯丙胺使用情况的监测,并针对年轻的、使用多种药物的、暴饮酒精的无家可归成年人开展甲基苯丙胺使用预防和减少工作。
