Abstract

OBJECTIVES

To assess the risks for HIV infection and sexually transmitted diseases (STD) among young northern Thai men who have sex with men (MSM), and to examine the possible role of male same-sex behavior in the northern Thai HIV/AIDS epidemic.

METHODS

Two cohorts of northern Thai military conscripts and one cohort of recently discharged conscripts, a total of 2047 men, were studied. Data were collected by interview on behavioral risk factors, and sera were examined for syphilis and HIV-1 antibodies. Univariate and multiple logistic regression analyses were used to determine risk factors associated with HIV and STD, and to assess the frequency and patterns of same-sex behaviors among these men.

RESULTS

Of 2047 men, 134 (6.5%) reported one or more male lifetime sex partners. Of these MSM, 130 (97.0%) also had female partners, and four (3.0%) had exclusively male partners. Compared with men who reported only female sex partners, MSM had a higher number of lifetime sex partners, a higher mean number of female sex partners, more female and male commercial sex worker (CSW) partners, and were more likely to be married. MSM were significantly more likely than exclusively heterosexual men to report having had any STD [odds ratio (OR), 2.72], gonorrhea (OR, 2.05), syphilis (OR, 3.17), non-gonococcal urethritis (OR, 4.54) and penile discharges (OR, 6.24). They were at borderline increased risk for HIV infection [OR, 1.51; 95% confidence interval (CI), 0.95-2.41]. Men with more than one lifetime male sex partner compared with those with only one partner were significantly more likely to be HIV-infected (OR, 2.81; 95% CI, 1.09-7.19).

CONCLUSIONS

Northern Thai MSM are a high-risk population for STD, including HIV. Reported same-sex behavior in this population appears to vary considerably with data collection techniques. HIV and STD prevention strategies aimed at changing unsafe sexual practices may need to be targeted to the general population of young Thai men.

摘要

目的

评估泰国北部与男性发生性行为的男性（MSM）感染艾滋病毒和性传播疾病（STD）的风险，并探讨男性同性性行为在泰国北部艾滋病毒/艾滋病流行中可能发挥的作用。

方法

对泰国北部的两批应征入伍军人和一批近期退伍军人进行了研究，共计2047名男性。通过访谈收集行为危险因素数据，并检测血清中的梅毒和HIV-1抗体。采用单因素和多因素逻辑回归分析来确定与艾滋病毒和性传播疾病相关的危险因素，并评估这些男性中同性性行为的频率和模式。

结果

在2047名男性中，134名（6.5%）报告有过一个或多个男性性伴侣。在这些MSM中，130名（97.0%）也有女性伴侣，4名（3.0%）只有男性伴侣。与仅报告有女性性伴侣的男性相比，MSM的终身性伴侣数量更多，女性性伴侣的平均数量更多，有更多的女性和男性商业性工作者（CSW）伴侣，且更有可能已婚。MSM报告患有任何性传播疾病的可能性显著高于仅为异性恋的男性[比值比（OR），2.72]，淋病（OR，2.05），梅毒（OR，3.17），非淋菌性尿道炎（OR，4.54）和阴茎分泌物（OR，6.24）。他们感染艾滋病毒的风险处于临界升高水平[OR，1.51；95%置信区间（CI），0.95 - 2.41]。与只有一个男性性伴侣的男性相比，有一个以上男性性伴侣的男性感染艾滋病毒的可能性显著更高（OR，2.81；95%CI，1.09 - 7.19）。
