Abstract：
Peer advocacy can promote HIV protective behaviors, but little is known about the concordance on prevention advocacy(PA) reports between people living with HIV(PLWH) and their social network members. We examined prevalence and correlates of such concordance, and its association with the targeted HIV protective behavior of the social network member. Data were analyzed from 193 PLWH(index participants) and their 599 social network members(alters). Kappa statistics measured concordance between index and alter reports of PA in the past 3 months. Logistic and multinomial regressions evaluated the relationship between advocacy concordance and alter condom use and HIV testing behavior and correlates of PA concordance. Advocacy concordance was observed in 0.3% of index-alter dyads for PrEP discussion, 9% for condom use, 18% for HIV testing, 26% for care engagement, and 49% for antiretroviral use discussions. Fewer indexes reported condom use(23.5% vs. 28.1%;[Formula: see text]=3.7, p=0.05) and HIV testing(30.5% vs. 50.5%; [Formula: see text]=25.3, p<0.001) PA occurring. Condom advocacy concordance was higher if the index and alter were romantic partners(OR=3.50; p=0.02), and lower if the index was 10 years younger than the alter(OR=0.23; p = 0.02). Alters had higher odds of using condoms with their main partner when both reported condom advocacy compared to dyads where neither reported advocacy(OR=3.90; p<0.001) and compared to dyads where only the index reported such advocacy(OR = 3.71; p=0.01). Age difference and relationship status impact advocacy agreement, and concordant perceptions of advocacy are linked to increased HIV protective behaviors. Alters\' perceptions may be crucial for behavior change, informing strategies for improving advocacy.
摘要：
同伴倡导可以促进艾滋病毒保护行为，但对艾滋病毒感染者(PLWH)及其社交网络成员之间的预防宣传(PA)报告的一致性知之甚少.我们检查了这种一致性的患病率和相关性，及其与社交网络成员的针对性HIV保护行为的关联。对193名PLWH（索引参与者）及其599名社交网络成员（改变者）的数据进行了分析。Kappa统计数据测量了过去3个月中PA指数和改变报告之间的一致性。Logistic和多项回归评估了倡导一致性与改变避孕套使用和HIV检测行为之间的关系以及PA一致性的相关性。在PrEP讨论中，在0.3％的指数改变二元组中观察到倡导一致性，9%用于避孕套使用，18%用于艾滋病毒检测，26%的护理参与度，49%用于抗逆转录病毒使用讨论。报告使用避孕套的指数较少（23.5%与28.1%；[公式：见正文]=3.7，p=0.05）和艾滋病毒检测（30.5%与50.5%;[式:见正文]=25.3,p<0.001)PA发生。如果指数和改变是浪漫伴侣，则避孕套倡导一致性更高（OR=3.50；p=0.02），如果该指数比改变者年轻10岁，则更低(OR=0.23；p=0.02)。当两个人都报告了避孕套宣传时，与均未报告宣传的二元组相比（OR=3.90；p<0.001），并且与仅有指数报告这种宣传的二元组相比（OR=3.71；p=0.01）。年龄差异和关系状况影响倡导协议，对宣传的一致看法与增加的艾滋病毒保护行为有关。改变观念可能对行为改变至关重要，宣传改进宣传的战略。
