Given the significant rise in methamphetamine use and related mortality in the United States, it is critical to explore differences in treatment trends with particular attention to women and ethnoracial groups in hard-hit areas like Los Angeles County.
We analyzed a large sample across 4 waves: 2011 (105 programs, 10 895 clients), 2013 (104 programs, 17 865 clients), 2015 (96 programs, 16 584 clients), and 2017 (82 programs, 15 388 clients). We completed a comparative analysis to identify differences across subgroups and a trend analysis of treatment episodes by gender and ethnoracial group to differentiate users of methamphetamine and users of other drugs.
Treatment clients using methamphetamine increased over time for each gender and race. There were also significant differences across age groups. Women comprised a greater proportion of treatment episodes involving methamphetamine use (43.3%) compared to all other drugs combined (33.6%). Latinas represented 45.5% of methadone-related admissions. Compared with other drug users, methamphetamine users had a lower successful treatment completion rate and were served by programs with less financial and culturally responsive capacity.
Findings highlight a sharp increase in treatment admissions for methamphetamine users of all gender and ethnocultural groups. Women, especially Latinas, saw the most significant increases, with a widening gender gap over time. All subgroups of methamphetamine users had a lower treatment completion rate compared with users of other drugs, and critical differences existed in the programs where they received services.
鉴于美国甲基苯丙胺使用量及其相关死亡率显著上升，探索治疗趋势的差异至关重要，尤其要关注洛杉矶县等受重创地区的女性和种族群体。
我们分析了来自4个时间点的大量样本：2011年（105个项目，10895名客户）、2013年（104个项目，17865名客户）、2015年（96个项目，16584名客户）和2017年（82个项目，15388名客户）。我们进行了比较分析以确定亚组间的差异，并对按性别和种族划分的治疗疗程进行了趋势分析，以区分甲基苯丙胺使用者和其他药物使用者。
随着时间推移，各性别和种族中使用甲基苯丙胺的治疗客户数量均有所增加。不同年龄组之间也存在显著差异。与使用所有其他药物的治疗疗程总和（33.6%）相比，涉及使用甲基苯丙胺的治疗疗程中女性所占比例更大（43.3%）。拉丁裔女性占美沙酮相关入院人数的45.5%。与其他药物使用者相比，甲基苯丙胺使用者的治疗成功率较低，且接受服务的项目在财务和文化响应能力方面较弱。
研究结果表明，所有性别和族裔文化群体中甲基苯丙胺使用者的治疗入院人数急剧增加。女性，尤其是拉丁裔女性增加最为显著，且随着时间推移性别差距不断扩大。与其他药物使用者相比，甲基苯丙胺使用者的所有亚组治疗完成率都较低，且他们接受服务的项目存在关键差异。
