Alcohol use has been suggested to interfere with condom use and to increase sexual risk behaviors. However, data on the prevalence of this practice among female sex workers and its association with condom use and sexually transmitted infections (STIs) are limited.
Data were collected through the baseline survey of an HIV prevention project among 454 establishment-based female sex workers in Guangxi, China, in 2004. Both global association and situational analysis were performed using 2 measures of alcohol use (alcohol intoxication and drinking alcohol before having sex with a client). Multiple logistic regression analyses were performed to examine the association of alcohol use with women's condom use and STIs.
One-third of women reported being intoxicated with alcohol at least once a month during the previous 6 months, and about 30% reported using alcohol before having sex with clients. In comparison with women who did not use alcohol before engaging in sex with clients, women who did so reported significantly less consistent condom use and higher rates of both current STIs and a history of STI. However, alcohol intoxication was not associated with condom use and STIs. These findings indicate event-specific rather than global associations of alcohol use with inconsistent condom use and STIs.
Alcohol use before commercial sex is associated with unprotected sex and increased risk for STIs. Interventions that address both alcohol use and HIV risk behaviors in the context of commercial sex may have a great impact in preventing the spread of HIV in China.
有研究提示，饮酒可能会干扰安全套的使用，并增加性行为相关的风险行为。然而，目前有关女性性工作者中这一行为的流行情况及其与安全套使用和性传播感染（STI）的关联的数据十分有限。
数据来源于 2004 年在中国广西进行的一个艾滋病毒预防项目的基线调查，共纳入 454 名场所内女性性工作者。采用两种饮酒测量指标（醉酒和与客人发生性行为前饮酒），分别进行了整体关联分析和情境分析。采用多因素 logistic 回归分析，评估了饮酒与女性安全套使用和 STI 的关联。
三分之一的女性报告称在过去 6 个月中至少每月有过一次醉酒经历，约 30%的女性报告在与客人发生性行为前饮酒。与未在与客人发生性行为前饮酒的女性相比，有此行为的女性报告安全套使用更不规律，且当前 STI 和既往 STI 的发生率更高。然而，醉酒与安全套使用和 STI 均无关联。这些结果提示饮酒与安全套使用不规律和 STI 之间存在事件特异性而非整体相关性。
商业性行为前饮酒与无保护性行为和 STI 风险增加相关。在商业性行为背景下同时解决饮酒和艾滋病毒风险行为问题的干预措施，可能会对中国艾滋病毒的传播产生重大影响。
