Compared to the general population, men who have sex with men (MSM) are at greater risk for HIV and less understood due to their more hidden and stigmatized nature. Moreover, the discrepancy in findings in the literature merits further investigations in MSM populations from different cultures and settings. We therefore conducted this study to explore factors associated with inconsistent condom use among high-risk MSM in Cambodia.
This cross-sectional study was conducted in 2014 among 367 MSM randomly selected from Battembang and Siem Reap using a two-stage cluster sampling method. A structured questionnaire was used for face-to-face interviews to collect information on characteristics of respondents, HIV testing history, self-perception of HIV risk, substance use, sexual behaviors, mental disorders, and HIV knowledge. Multivariable logistic regression analysis was performed to identify factors independently associated with inconsistent condom use.
On average, 62.3% of respondents reported that they always used condoms over the past three months. The rates varied with types of sexual partners; the proportion of respondents who reported always using condoms was 55.1%, 64.2%, 75.9%, 73.0%, 78.1%, and 70.3%, for sexual partners who were girlfriends, boyfriends, female sex workers, male sex workers, female clients, or male clients, respectively. After adjustment, inconsistent condom use was significantly associated with age of ≥25 (AOR = 1.77, 95% CI = 1.09-2.86), self-rated quality of life as good or very good (AOR = 4.37, 95% CI = 1.79-5.67), self-perception of higher HIV risk compared to the general population (AOR = 2.37, 95% CI = 1.35-4.17), illicit drug use in the past three months (AOR = 5.76, 95% CI = 1.65-10.09), and reported consistent lubricant use when selling anal sex to men in the past three months (AOR = 2.85, 95% CI = 1.07-8.12).
We found risky sexual behaviors to be considerably high among MSM in this study, especially among those who used illicit drugs or were older than 25. HIV education and social marketing should be expanded and specifically designed for MSM to better educate on the increased risk of HIV with unprotected anal sex and illicit drug use as risk factors, and the importance of the use of both condoms and lubricant during anal intercourse.
与普通人群相比,男男性行为者(MSM)感染艾滋病毒的风险更高,且由于其行为更为隐秘和受污名化,人们对他们的了解较少。此外,文献研究结果存在差异,这值得对来自不同文化和环境的男男性行为者群体进行进一步调查。因此,我们开展了这项研究,以探索柬埔寨高危男男性行为者中与不坚持使用避孕套相关的因素。
2014年,我们采用两阶段整群抽样方法,从马德望和暹粒随机抽取了367名男男性行为者,开展了这项横断面研究。使用结构化问卷进行面对面访谈,收集受访者的特征、艾滋病毒检测史、对艾滋病毒风险的自我认知、物质使用情况、性行为、精神障碍以及艾滋病毒知识等信息。进行多变量逻辑回归分析,以确定与不坚持使用避孕套独立相关的因素。
平均而言,62.3%的受访者表示在过去三个月里他们一直使用避孕套。使用避孕套的比例因性伴侣类型而异;对于女朋友、男朋友、女性性工作者、男性性工作者、女性客户或男性客户等性伴侣,报告一直使用避孕套的受访者比例分别为55.1%、64.2%、75.9%、73.0%、78.1%和70.3%。调整后,不坚持使用避孕套与年龄≥25岁(比值比[AOR]=1.77,95%置信区间[CI]=1.09 - 2.86)、自评生活质量为良好或非常良好(AOR = 4.37,95% CI = 1.79 - 5.67)、自我认知的艾滋病毒风险高于普通人群(AOR = 2.37,95% CI = 1.35 - 4.17)、过去三个月内使用非法药物(AOR = 5.76,95% CI = 1.65 - 10.09)以及报告在过去三个月向男性出售肛交服务时一直使用润滑剂(AOR = 2.85,95% CI = 1.07 - 8.12)显著相关。
我们发现,在本研究中,男男性行为者的危险性行为相当高,尤其是那些使用非法药物或年龄超过25岁的人。应扩大针对男男性行为者的艾滋病毒教育和社会营销,并专门设计相关内容,以便更好地教育他们了解无保护肛交和使用非法药物作为危险因素会增加感染艾滋病毒的风险,以及在肛交过程中使用避孕套和润滑剂的重要性。
