Abstract：
UNASSIGNED: High HIV prevalence among injecting drug users (IDUs) remains a cause of concern and are considered key drivers of concentrated epidemic in India. The present paper aims to assess the effectiveness of the targeted intervention (TI) program on the risk behaviors among IDUs across regions of India.
UNASSIGNED: This paper used the data from the integrated biological and behavioral surveillance 2014-2015 among the IDUs in India. Descriptive statistics and propensity score matching analysis was carried out to understand the effectiveness of the TI program on the new needle/syringe used and needle/syringe shared in the last injecting episode by accounting for the covariates.
UNASSIGNED: The matched samples estimate, i.e., average treatment effect on treated of new needles/syringe used and shared in the last injecting episode by those who received needles/syringes from peer educator or outreach workers (PE/ORWs) and those who did not receive was 2.8% (confidence interval [CI]: 0.05-5.6) increase in the use of new needles/syringes and 6.5% (CI: -9.7--3.3) decrease in the needles/syringes shared in last injecting episode indicating that IDUs who received new needles/syringes from PE/ORWs are more likely to use new needle/syringe and less likely to share needle/syringes to those who did not receive needles/syringes. The results vary across the different regions of India.
UNASSIGNED: TI program proves to be an effective initiative in the behavior change among IDUs as substantiated by use of new needles/syringes and decreased sharing of needles/syringes. TI program coverage varies from region to region and may further be expanded to accelerate the program services to prevent HIV/AIDS.

摘要：
注射吸毒者（IDUs）中艾滋病毒的高流行率仍然令人担忧，被认为是印度集中流行的主要驱动因素。本文旨在评估针对性干预（TI）计划对印度各地区注射吸毒者风险行为的有效性。
■本文使用了印度IDU中2014-2015年综合生物和行为监测的数据。进行描述性统计和倾向评分匹配分析,以通过考虑协变量来了解TI计划对使用的新针头/注射器和在最后一次注射事件中共享的针头/注射器的有效性。
■匹配样本估计，即，接受同伴教育者或外展工作者(PE/ORWs)和未接受新针头/注射器的人在上次注射事件中使用和共享的新针头/注射器的平均治疗效果为2.8%(置信区间[CI]:0.05-5.6),使用新针头/注射器的增加和6.5%(CI:-9.7--3.3),在上次注射事件中使用新针头/注射器的人可能没有接受新针头/注射器的人结果因印度不同地区而异。
■通过使用新的针头/注射器和减少针头/注射器的共享，TI计划被证明是IDU行为改变的有效举措。TI计划的覆盖范围因地区而异，可能会进一步扩大，以加快计划服务以预防艾滋病毒/艾滋病。
