目标：确定农村地区吸毒成年人的代表性样本中艾滋病毒的血清流行率。此外，还旨在确定农村地区的年轻吸毒成年人是否比年长的吸毒成年人有更高水平的性危险行为。方法：对 503 名成年吸毒者进行横断面研究。使用艾滋病毒抗体快速检测，并通过计算机收集自我报告的数据。结果：没有参与者的艾滋病毒抗体检测呈阳性。在双变量测试中，年轻参与者和年长参与者之间仅观察到 2 个差异。年轻男性更有可能进行无保护的阴道性交 (P = .018)，年轻女性更有可能与注射吸毒者进行无保护的性行为 (P = .016)。在受控多变量分析中，年龄与 8 项风险行为指数（β = -0.15）和降低的 6 项风险指数（β = -0.18）有适度但显着的关联。结论：尽管性网络相当密集且互动，性风险行为水平相对较高，但该农村人口尚未受到艾滋病毒流行的影响。如果该人群中爆发艾滋病毒，观察到的性行为水平表明，吸毒人群中可能会发生快速性传播，并且可能包括所有年龄段的人。 (C) 2012 Elsevier Inc. 保留所有权利。
Objectives: To determine the seroprevalence of HIV among a representative sample of drug-using adults in a rural area. Also, to determine whether young drug-using adults in a rural area engage in greater levels of sexual risk behavior than their older counterparts.Methods: Cross-sectional study of 503 adult drug users. Rapid tests for antibodies to HIV were used, and self-reported data were collected via computer.Results: None of the participants tested positive for antibodies to HIV. In bivariate tests, only 2 differences were observed between young and older participants. Young males were more likely to engage in unprotected vaginal sex (P = .018) and young females were more likely to engage in unprotected sex with persons injecting drugs (P = .016). In controlled multivariate analyses, age had a modest but significant association with an 8-item index of sexual risk behavior (beta = -0.15) and a reduced 6-item index of risk (beta = -0.18).Conclusion: Despite a fairly dense and interactive sexual network and relatively high-levels of sexual risk behaviors, this rural population has not yet been affected by the HIV epidemic. In the event an outbreak of HIV in this population the observed levels of sexual behavior suggest that rapid sexual transmission could occur among drug-using populations and may include persons of all ages.
