From 2004 to 2008 a new Asian highway was constructed through remote multiethnic areas of north Laos linking a low with higher HIV prevalence areas in bordering Thailand and China. We assessed the HIV vulnerability in four minority villages alongside the new road in Luang Namtha Province using structured interviews and voluntary counselling and testing (VCT) for HIV. Of 470 villagers aged 15-49 years old, 47.0% did not know any ways of HIV transmission yet 82.1% reported sexual contacts. Median age at first sex was 17.5 years. Sex of never-married 15-24 years old was associated with higher age (P = 0.002) and ethnicity (P = 0.013; Hmong odds ratio [OR] 7.27); 61.9% (86/139) used no condom at last non-cohabitant sex, especially women (OR 17.7, P < 0.001) and older villagers (P = 0.001). No HIV-infection was detected among villagers who received VCT in 2006 (924 of 933) and 2008 (538 of 1249). Nonetheless our findings reveal an alarming vulnerability for HIV among ethnic minorities alongside the new highway, and further culturally adapted prevention efforts are warranted.
2004年至2008年，一条新的亚洲公路穿过老挝北部偏远的多民族地区，连接了泰国和中国边境地区艾滋病病毒（HIV）感染率较低和较高的地区。我们通过结构化访谈以及HIV自愿咨询检测（VCT），对琅南塔省新公路沿线的四个少数民族村庄的HIV易感性进行了评估。在470名年龄在15至49岁的村民中，47.0%的人不知道任何HIV传播途径，但82.1%的人报告有性接触。首次性行为的中位年龄为17.5岁。15至24岁未婚者的性行为与年龄较大（P = 0.002）以及种族（P = 0.013；苗族优势比[OR]为7.27）有关；61.9%（86/139）的人在最后一次性非同居性行为中未使用避孕套，尤其是女性（OR 17.7，P < 0.001）和年长村民（P = 0.001）。在2006年（933人中的924人）和2008年（1249人中的538人）接受VCT的村民中未检测到HIV感染。尽管如此，我们的研究结果显示，新公路沿线少数民族的HIV易感性令人担忧，有必要进一步开展适合当地文化的预防工作。
