Between 2010 and 2015, Eswatini conducted mass media health behavior campaigns (HBCs) designed to avert new HIV infections. Using longitudinal data from the nationally representative Swaziland HIV Incidence Measurement Survey of 2011, we describe the impact of exposure to HBCs on selected HIV risk behaviors and HIV incidence among sexually active, HIV-negative adults (n = 11,232). Exposure to partner reduction HBCs was significantly associated with reporting fewer (i.e., 1 versus 2, or 2 versus ≥ 3) sexual partners in the prior 6 months at baseline among women (aOR = 3.02; 95% CI 1.38, 6.62); and at both baseline and at 6-months follow-up for men (aOR = 2.26; 95% CI 1.49, 3.44; aOR = 1.95, 95% CI [1.26-3.00], respectively). Despite these reported partner reductions, there was no association between HBC exposure and prospectively observed HIV seroconversions (n = 121). This analysis strengthens the evidence that HIV prevention at the population level requires integrated strategies.

斯威士兰健康行为运动对艾滋病毒危险行为和艾滋病毒发病率影响的纵向分析。


2010 年至 2015 年间，斯威士兰开展了大众媒体健康行为运动 (HBC)，旨在避免新的艾滋病毒感染。利用 2011 年斯威士兰全国代表性艾滋病毒发病率测量调查的纵向数据，我们描述了接触 HBC 对性活跃、艾滋病毒阴性成年人 (n = 11,232) 中选定的艾滋病毒危险行为和艾滋病毒发病率的影响。女性中，在基线前 6 个月内，接触伴侣减少 HBC 与报告的性伴侣较少（即 1 对 2，或 2 对 ≥ 3）显着相关（aOR = 3.02；95% CI 1.38，6.62）；男性的基线和 6 个月随访（分别为 aOR = 2.26；95% CI 1.49、3.44；aOR = 1.95、95% CI [1.26-3.00]）。尽管有报道称伴侣数量减少，但 HBC 暴露与前瞻性观察到的 HIV 血清转化之间没有关联 (n = 121)。该分析强化了人口一级艾滋病毒预防需要综合战略的证据。
