改变观念的时机已到:尽管提供了避孕套和润滑剂,并提供了咨询服务,但尼日利亚男男性行为者和跨性别女性仍有限制地使用避孕套和润滑剂。

Abstract

PURPOSE

This study characterized availability and uptake of condoms and condom-compatible lubricants (CCLs) at community-engaged condom education and distribution programs serving cisgender men who have sex with men and transgender women in Abuja and Lagos, Nigeria.

METHODS

Condoms and water-based CCLs were freely available to participants in the TRUST/RV368 cohort. Factors associated with their consistent use were assessed using Poisson regression with robust error variance to estimate relative risks (RRs) and 95% confidence intervals (CIs).

RESULTS

From March 2013-November 2017, 2090 cisgender men who have sex with men and transgender women enrolled with HIV prevalence 40.4% and incidence 12.8 cases per 100 person-years. Fifteen months after enrollment, the proportion who reported consistent condom and CCL use increased during receptive anal sex (21.7%-67.1%, P < .001) and insertive anal sex (25.4%-67.8%, P < .001). Multivariable analyses demonstrated independent impact of 15 months in care on uptake during both receptive (RR 2.62 [95% CI 2.29-3.00]) and insertive (RR 2.27 [95% CI 2.01-2.57]) sex.

CONCLUSIONS

Engagement in care improved condom and CCL uptake over time but inconsistent use remained common. Novel approaches to further increase uptake must be pursued alongside complementary strategies, such as sustained access to antiretroviral therapy for those living with HIV and provision of pre and postexposure prophylaxis for those at risk.

摘要

目的

本研究描述了在阿布贾和拉各斯为与男性发生性行为的 cisgender 男性和跨性别女性提供的社区参与的 condom 教育和分发项目中, condom 和 condom 兼容润滑剂(CCL)的供应和使用情况。

方法

TRUST/RV368 队列中的参与者可自由获得 condom 和水基 CCL。使用泊松回归和稳健误差方差来评估与它们持续使用相关的因素,以估计相对风险(RR)和 95%置信区间(CI)。

结果

2013 年 3 月至 2017 年 11 月,共有 2090 名与男性发生性行为的 cisgender 男性和跨性别女性入组,HIV 感染率为 40.4%,发病率为每 100 人年 12.8 例。入组后 15 个月,报告在接受性肛交(21.7%-67.1%,P<.001)和插入性肛交(25.4%-67.8%,P<.001)中持续 condom 和 CCL 使用的比例增加。多变量分析表明,15 个月的护理对接受性(RR 2.62[95%CI 2.29-3.00])和插入性(RR 2.27[95%CI 2.01-2.57])性行为的使用均有独立影响。

结论

随着时间的推移,参与护理改善了 condom 和 CCL 的使用,但仍存在使用不规范的情况。必须探索新的方法来进一步提高使用率,同时还需要采取补充策略,如为 HIV 感染者持续提供抗逆转录病毒治疗,并为处于风险中的人提供暴露前和暴露后预防。
