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.
■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。
