The "HIV risk environment" has been characterized as a dynamic interplay between structural and network factors. However, most HIV prevention research has not examined the independent and combined impact of network and structural factors. We aimed to identify individual, network, and neighborhood correlates of exchange sex (≥1 exchange sex partner, past 90 days) among female non-injection drug users (NIDUs). We used baseline data from 417 NIDUs enrolled in a randomized HIV prevention trial in Baltimore (2005-2007). Surveys ascertained demographic variables, drug/sex risk behaviors, neighborhood perceptions, and social/sexual network characteristics. Correlates of exchange sex were identified with descriptive statistics and log-binomial regression. Our findings suggest that sex and drug relationships among female NIDUs are interlinked and may be difficult to modify without altering social norms. Strengthening ties that provide social support but not drug support and reducing ties that provide both drug and social support may facilitate reductions in individual-level HIV-risk behaviors.
“HIV 风险环境”被定义为结构和网络因素之间的动态相互作用。然而，大多数 HIV 预防研究并未检验网络和结构因素的独立和综合影响。我们旨在确定个体、网络和邻里因素与女性非注射吸毒者（NIDU）之间的交换性行为（≥1 个交换性伴侣，过去 90 天）的相关性。我们使用了在巴尔的摩（2005-2007 年）参加一项随机 HIV 预防试验的 417 名 NIDU 的基线数据。调查确定了人口统计学变量、药物/性行为风险行为、邻里感知以及社会/性网络特征。使用描述性统计和对数二项式回归确定了与交换性行为相关的因素。我们的研究结果表明，女性 NIDU 之间的性行为和药物关系是相互关联的，如果不改变社会规范，可能很难改变。加强提供社会支持但不提供药物支持的关系，减少既提供药物又提供社会支持的关系，可能有助于减少个人层面的 HIV 风险行为。
