Injecting drug use and unsafe sexual practice are both considered major risk factors for HIV infection. This study reports sexual behaviors among male "current" (i.e. using heroin and/or opium at least once in the past 3 months) and "ex-" opiate users in Chiang Rai province in Northern Thailand. Between January 1999 and August 2000, 206 male opiate users were recruited by mail callback. Of the 206 drug users, 89 (43.2%) could be classified as current users. Current users did not differ from ex-users, except for educational level and ethnicity. Current and ex-opiate users showed no difference in number of regular sexual partners, proportion of having sex with commercial and non-commercial sex partners, and reported histories of sexually transmitted diseases. This study suggests that the importance of sexual risk behaviors in HIV transmission cannot be ignored in both current and ex-opiate users.
注射吸毒和不安全的性行为都被视为感染艾滋病毒的主要风险因素。本研究报告了泰国北部清莱省男性“当前”（即在过去3个月内至少使用过一次海洛因和/或鸦片）和“曾经的”阿片类药物使用者的性行为情况。1999年1月至2000年8月期间，通过邮件回访招募了206名男性阿片类药物使用者。在这206名吸毒者中，89名（43.2%）可被归类为当前使用者。除了教育程度和种族外，当前使用者与曾经的使用者没有差异。当前和曾经的阿片类药物使用者在固定性伴侣数量、与商业性和非商业性性伴侣发生性行为的比例以及报告的性传播疾病病史方面没有差异。这项研究表明，在当前和曾经的阿片类药物使用者中不可忽视性风险行为在艾滋病毒传播中的重要性。
