Vietnam's HIV epidemic is driven by injection drug use. Most IDUs are sexually active and may infect their female sexual partners (SPs). We implemented peer-based HIV prevention interventions for SPs in Hanoi. This paper reports on an evaluation of these interventions based on cross-sectional surveys of SPs. Our data show that this population can be reached, relationships improved, and consistent condom use increased (27% at 24 months up from 16% at 12 months: P = 0.002). Self-reported condom use at last sex was 3.5 times higher among participants in the intervention than among non-participants after controlling for selection bias, indicating a possible intervention effect. However, no significant association was found for consistent condom use in the previous 6 months. Many SPs remain at risk for HIV and interventions must promote a range of HIV prevention strategies including consistent condom use, lower risk sexual activity, and ARV treatment as prevention.
越南的艾滋病疫情是由注射吸毒引起的。大多数吸毒者具有性活跃性，并可能感染他们的女性性伴侣（SP）。我们在河内为 SP 实施了基于同伴的艾滋病预防干预措施。本文根据对 SP 的横断面调查，报告了对这些干预措施的评估结果。我们的数据表明，这个人群是可以接触到的，可以改善关系，并增加了 condom 的使用（24 个月时为 27%，12 个月时为 16%：P = 0.002）。在控制了选择偏差后，与非参与者相比，参与者中最后一次性行为使用 condom 的比例高出 3.5 倍，表明可能存在干预效果。然而，在过去 6 个月内， condom 的一致性使用与干预措施没有显著关联。许多 SP 仍然面临 HIV 感染的风险，干预措施必须促进一系列 HIV 预防策略，包括 condom 的一致性使用、降低风险的性行为以及 ARV 治疗作为预防。
