STEP into Action assessed the efficacy of a peer-based HIV prevention intervention in reducing HIV risk behaviors among people who inject drugs (PWIDs) in Baltimore. This analysis examined the effect of the intervention on the change in frequency of conversation about HIV prevention topics over time. 114 participants were randomized into an experimental and 113 into a control group. Data was collected prospectively at 6, 12, and 18 months. The experimental group talked more frequently about HIV prevention topics compared to the control group at 6-month visit. At 18 months relative risk ratios (RRR) remained statistically significant for conversation about the danger of needle sharing (RRR = 3.21) and condom use (RRR = 2.81). The intervention resulted in an increased conversation about HIV prevention among PWIDs, but the sustainability past 6 months remained a challenge; suggesting that interventions should be designed to constantly reinforce communication about HIV prevention among PWIDs.
“立即行动”项目评估了一种基于同伴的艾滋病病毒预防干预措施在降低巴尔的摩注射吸毒者(PWIDs)感染艾滋病病毒风险行为方面的效果。该分析考察了干预措施对随着时间推移艾滋病病毒预防话题交流频率变化的影响。114名参与者被随机分为实验组,113名被分为对照组。前瞻性地在6个月、12个月和18个月时收集数据。在6个月的随访中,与对照组相比,实验组更频繁地谈论艾滋病病毒预防话题。在18个月时,关于共用针头危险(相对风险比RRR = 3.21)和使用安全套(RRR = 2.81)的交流,相对风险比在统计学上仍具有显著意义。该干预措施使注射吸毒者之间关于艾滋病病毒预防的交流有所增加,但6个月后的可持续性仍是一项挑战;这表明应设计干预措施以不断加强注射吸毒者之间关于艾滋病病毒预防的沟通。
