Vietnam (2011): TRaC Behavioral survey among female sex workers and female sex workers who inject drugs. Round 2

In 2011 PSI/Vietnam conducted a second, behavioral survey among 1,666 SW in 7 provinces, including 315 SW-IDUs in 3 project provinces using RDS. Sex workers were recruited in 7 of the priority PEPFAR provinces. The objectives of the survey were to monitor trends (2008 vs. 2011) and assess associations between exposure to programs and behavior change. The study concludes that: 1. A large number of sex workers report no contact with any HIV prevention intervention. 2. There has been an overall decrease in consistent condom use between 2008 and 2011 driven primarily by decreases in 3 provinces, however SW exposed to HIV prevention programming through outreach and drop-in centers are more likely to report consistent condom use. 3. Sex workers report relatively high levels of condom availability at outlets where commercial sex takes place. Fully-subsidized or \"free\" condom access is common. 4. Subsidy, quality and accessibility are key factors influencing condom brand preference and purchase behavior. 5. There has been an increase in reported use of VCT among 2008 and 2011, although use rates overall remain low. Chan Troi Moi social marketing campaigns have contributed to increased use of VCT. 6. Sex workers exposed to Song Dep outreach are less likely to report having a non-injector to inject for the first time.

2011年，PSI/越南在7个省份的1666名性工作者（sex workers, SW）中开展了第二轮行为学调查，其中在3个项目省份通过应答者驱动抽样（Respondent-Driven Sampling, RDS）招募了315名注射吸毒性工作者（SW-IDUs）。本次调查的招募范围覆盖7个重点总统防治艾滋病紧急救援计划（PEPFAR）省份。
本次调查的目标为监测2008年与2011年的趋势，并评估项目接触与行为改变之间的关联。该研究得出以下结论：
1. 大量性工作者表示未接触过任何艾滋病预防干预措施。
2. 2008年至2011年间，安全套持续使用率整体呈下降趋势，这主要由3个省份的使用率下滑所驱动；不过，通过外展服务与落足点中心接触艾滋病预防项目的性工作者，报告持续使用安全套的比例更高。
3. 性工作者表示，在提供商业性服务的场所中，安全套可及性相对较高，全额补贴或“免费”安全套的获取渠道较为普遍。
4. 补贴政策、安全套质量与可及性是影响安全套品牌偏好与购买行为的关键因素。
5. 2008年至2011年间，报告接受过自愿咨询与检测（Voluntary Counseling and Testing, VCT）的性工作者比例有所上升，但整体使用率仍处于较低水平。"Chan Troi Moi"社会营销活动对提升VCT使用率起到了积极推动作用。
6. 接触过"Song Dep"外展服务的性工作者，首次由非注射者代为注射的报告率更低。
