Abstract

OBJECTIVE

To describe intravaginal practices (IVPs) among female sex workers (FSWs) who inject drugs in two cities-Tijuana and Ciudad Juarez-on the border between the USA and Mexico.

METHODS

Data for a secondary analysis were obtained from interviews conducted as part of a randomized controlled trial in FSWs who injected drugs between October 28, 2008, and May 31, 2010. Eligible individuals were aged at least 18years and reported sharing injection equipment and having unprotected sex with clients in the previous month. Descriptive statistics were used to assess frequency and type of IVPs. Logistic regression was used to assess correlates of IVPs.

RESULTS

Among 529 FSWs who completed both surveys, 229 (43.3%) had performed IVPs in the previous 6months. Factors independently associated with IVPs were reporting any sexually transmitted infection in the previous 6months (adjusted odds ratio [aOR] 1.8, 95% confidence interval [CI] 1.1-3.1; P=0.03), three or more pregnancies (aOR 1.9, 95% CI 1.1-3.2; P=0.02), and having clients who became violent when proposing condom use (aOR 5.8, 95% CI 1.0-34.3; P=0.05), which are all factors related to inconsistent condom use.

CONCLUSION

Screening for IVPs could help to identify FSW at increased risk of HIV, and facilitate conversations about specific risk-reduction methods.

摘要

目的

描述在美国和墨西哥边境的蒂华纳和华雷斯这两个城市中注射毒品的女性性工作者的阴道内行为（IVP）。

方法

二次分析的数据来自于2008年10月28日至2010年5月31日期间对注射毒品的女性性工作者进行的随机对照试验的访谈。符合条件的个体年龄至少为18岁，并报告在前一个月共用注射设备且与客户发生无保护性行为。描述性统计用于评估IVP的频率和类型。逻辑回归用于评估IVP的相关因素。

结果

在529名完成两项调查的女性性工作者中，229名（43.3%）在过去6个月内有过IVP行为。与IVP独立相关的因素包括在前6个月内报告患有任何性传播感染（调整后的优势比[aOR]为1.8，95%置信区间[CI]为1.1 - 3.1；P = 0.03）、三次或更多次怀孕（aOR为1.9，95% CI为1.1 - 3.2；P = 0.02）以及有客户在提议使用避孕套时变得暴力（aOR为5.8，95% CI为1.0 - 34.3；P = 0.05），这些都是与避孕套使用不一致相关的因素。
