Abstract

BACKGROUND

Female injecting drug users (IDUs) who are also sex workers (FSW-IDUs) is an important bridge population transmitting HIV from the IDU population to clients of FSWs. Little is known about the relationships between severity of drug dependence, economic pressure and relevant HIV-related risk behaviors.

METHODS

281 non-institutionalized participants were recruited using snowball sampling methods. Anonymous face-to-face interviews were administered by trained doctors.

RESULTS

64.1% of participants used condoms inconsistently with their clients in the past 6 months; 28.5% served at least 2 clients per day and 48.4% practiced at least one of the three studied needle sharing behaviors. Severity of drug dependence (adjusted OR=1.05, p<0.01) and economic pressure (adjusted OR=1.07 to 2.52, p<0.05) were significantly associated with inconsistent condom use with clients in the last 6 months. Severity of drug dependence (adjusted OR=1.15, p<0.01) and variables related to perceived economic pressure (adjusted OR=1.09-3.05, p<0.05) were significantly associated with higher frequency of commercial sex transaction. Severity of drug dependence (adjusted OR=1.07, p<0.01) were also associated with needle sharing behaviors. In summary models, severity of drug dependence (OR=1.17, p<0.001), economic pressure (OR=1.39, p<0.001) and their interaction term (OR=0.98, p<0.001) were all associated with inconsistent condom use with clients in the last 6 months.

CONCLUSIONS

Prevalence of unprotected commercial sex was high and was independently associated with severity of drug dependence and economic pressure; severity of drug dependence was also associated with needle sharing behaviors. Such issues need to be fully considered when planning research studies and interventions.

摘要

背景

女性注射吸毒者兼性工作者是将艾滋病病毒从注射吸毒人群传播给性工作者客户的重要桥梁人群。关于药物依赖严重程度、经济压力与相关艾滋病病毒相关风险行为之间的关系,人们了解甚少。

方法

采用滚雪球抽样方法招募了281名非机构化参与者。由经过培训的医生进行匿名面对面访谈。

结果

64.1%的参与者在过去6个月中与客户使用避孕套的情况不一致;28.5%的人每天至少接待2名客户,48.4%的人至少有三种研究的共用针头行为中的一种。药物依赖严重程度(调整后的比值比=1.05,p<0.01)和经济压力(调整后的比值比=1.07至2.52,p<0.05)与过去6个月中与客户使用避孕套情况不一致显著相关。药物依赖严重程度(调整后的比值比=1.15,p<0.01)以及与感知经济压力相关的变量(调整后的比值比=1.09 - 3.05,p<0.05)与更高频率的商业性交易显著相关。药物依赖严重程度(调整后的比值比=1.07,p<0.01)也与共用针头行为相关。在综合模型中,药物依赖严重程度(比值比=1.17,p<0.001)、经济压力(比值比=1.39,p<0.001)及其交互项(比值比=0.98,p<0.001)均与过去6个月中与客户使用避孕套情况不一致相关。

结论

无保护商业性行为的发生率很高,且与药物依赖严重程度和经济压力独立相关;药物依赖严重程度也与共用针头行为相关。在规划研究和干预措施时,需要充分考虑这些问题。
