目的性工作者（SW）是HIV感染风险增加的重点人群。本研究旨在探讨冒险行为，并评估艾滋病毒的流行之间SW在Portugues.Methods的横断面调查进行了1040 SW使用参与性研究方法。性工作者在性工作场所和社区组织办公室被招募。数据是通过一个问卷调查与训练有素的采访者收集的。艾滋病病毒快速检测进行了213 responders.Results报告的艾滋病病毒感染率为8%：17.6%的男性到女性的变性人，7.4%的女性和5%的男性。在据报感染艾滋病毒的性工作者中，52.2%报告曾经注射毒品。男性性工作者在过去一个月与客户不一致使用安全套的比例较高（26.5%），女性在过去一年与不付费伴侣不一致使用安全套的比例较高（71.3%）。在报告的HIV阳性性工作者中，避孕套使用不一致的比例较高。在多变量回归分析中，报告的艾滋病毒感染率在变性者中仍然显着较高（OR 6.4; 95% CI 1.7 - 24.3），老年人（OR 5.1; 95% CI 1.3 - 21.1），户外工作（OR 5.4; 95% CI 1.9 - 15.6），曾经使用过精神活性物质（OR 4.1; 95% CI 2.2 - 7.7），每月收入< 1000英镑（OR 2.6; 95% CI 1.2 - 5.9）。那些谁有一个HIV快速检测，8.9%的反应，73.7%不知道他们的血清positivity.Conclusions艾滋病毒感染的负担在SW是高的。必须持续努力促进艾滋病毒检测，以减少未确诊的感染。必须在有针对性的艾滋病毒干预措施中解决SW的不同风险特征。预防干预措施应系统地在SW的最高风险亚组中实施。
Objectives Sex workers (SW) are key populations at an increased risk of HIV infection. This study aimed to characterise risk-taking behaviours and assess HIV prevalence among SW in Portugal.Methods A cross-sectional survey was conducted with 1040 SW using a participatory research approach. SW were recruited in sex-work locations and community-based organisation offices. Data were collected through a questionnaire with trained interviewers. An HIV rapid test was performed in 213 respondents.Results Reported HIV prevalence was 8%: 17.6% of man-to-woman transgenders, 7.4% of women and 5% of men. Of SW reportedly living with HIV, 52.2% reported ever injecting drug use. Inconsistent condom use with clients in the last month was higher among male SW (26.5%) and with non-paying partners in the last year was higher among women (71.3%). Among reported HIV-positive SW, the proportions of inconsistent condom use were high. In multivariate regression analysis, reported HIV infection remained significantly higher among transgenders (OR 6.4; 95% CI 1.7 to 24.3), those older (OR 5.1; 95% CI 1.3 to 21.1), working outdoors (OR 5.4; 95% CI 1.9 to 15.6), having ever used psychoactive substances (OR 4.1; 95% CI 2.2 to 7.7) and earning < 1000 per month (OR 2.6; 95% CI 1.2 to 5.9). Of those who had an HIV rapid test, 8.9% were reactive; 73.7% were unaware of their seropositivity.Conclusions The HIV infection burden in SW is high. Efforts to promote HIV testing must be sustained in order to reduce undiagnosed infection. The diverse risk profiles of SW must be addressed in targeted HIV interventions. Prevention interventions should be systematically implemented within most-at-risk subgroups of SW.
