Young injection drug users (IDUs) are at risk for acquiring blood-borne diseases like HIV and Hepatitis C. Little is known about the population prevalence of young IDUs. We (1) estimate annual population prevalence rates of young IDUs (aged 15-29) per 10,000 in 95 large U.S. metropolitan statistical areas (MSAs) from 1992 to 2002; (2) assess the validity of these estimates; and (3) explore whether injection drug use among youth in these MSAs began to rise after HAART was discovered. A linear mixed model (LMM) estimated the annual population prevalence of young IDUs in each MSA and described trends therein. The population prevalence of IDUs among youths across 95 MSAs increased from 1996 (mean = 95.64) to 2002 (mean = 115.59). Additional analyses of the proportion of young IDUs using health services suggest this increase may have continued after 2002. Harm reduction and prevention research and programs for young IDUs are needed.
年轻的注射吸毒者（IDU）有感染艾滋病毒和丙型肝炎等血液传播疾病的风险。对于年轻 IDU 的人群流行率知之甚少。我们 (1) 估计了 1992 年至 2002 年期间 95 个美国大城市统计区 (MSA) 中每 10,000 名年龄在 15-29 岁的年轻 IDU 的年度人群流行率；(2) 评估了这些估计的有效性；(3) 探讨了在发现 HAART 后，这些 MSA 中年轻人的注射吸毒行为是否开始上升。线性混合模型 (LMM) 估计了每个 MSA 中年轻 IDU 的年度人群流行率，并描述了其中的趋势。95 个 MSA 中年轻人的 IDU 人群流行率从 1996 年（平均值 = 95.64）增加到 2002 年（平均值 = 115.59）。对使用卫生服务的年轻 IDU 比例的进一步分析表明，这种增长可能在 2002 年后仍在继续。需要为年轻的 IDU 提供减少伤害和预防研究和计划。
