| 目的 了解云南省艾滋病高流行区HIV阳转病例特征及其感染前艾滋病相关高危行为。方法 于2016年1-3月，采用普查法对德宏傣族景颇族自治州、红河哈尼族彝族自治州、临沧市和大理白族自治州2012-2015年451例HIV阳转病例开展调查。结果 在451例HIV阳转病例中，感染途径以异性性传播为主（92.5%，417/451）；艾滋病知识知晓率为73.0%（329/451）。得知感染前1年内，最近1次与固定性伴、临时性伴、商业性伴及男男同性性伴发生性行为安全套使用率分别为48.7%（167/343）、4.2%（7/165）、9.9%（15/151）、0.0%（0/3）。与固定性伴未使用安全套危险因素包括：居住在大理州、农民、非在婚状态、月收入≤ 1 000元、感染前生活在城镇地区且不知晓艾滋病相关知识；临时性行为未使用安全套危险因素包括：居住在德宏、红河、临沧地区、年龄≤ 30岁、职业为非农民。得知HIV感染前，有注射吸毒行为者占8.2%（37/450）、接受过艾滋病相关干预服务者占75.5%（340/450）。结论 云南省艾滋病高流行区HIV阳转病例中异性性传播感染比例较高，艾滋病知识知晓率、安全套使用率和接受干预服务比例均较低。 |

| Objective To understand the characteristics of newly detected HIV infection cases and related high risk behaviors in the areas with high HⅡV infection prevalence in Yunnan province. Methods A questionnaire survey was conducted with census method during January to March 2016 among newly detected HIV infected persons in Dehong, Honghe, Lincang and Dali prefectures in Yunnan during 2012-2015. Results Among 451 HIV seropositive cases, the major transmission route of HIV was heterosexual contact, accounting for 92.5% (417/451). The total awareness rate of AIDS related knowledge was 73.0% (329/451). The rates of condom use at sex with regular sexual partners, occasional sexual partners, commercial sexual partners and men who have sex with men within 1 year before knowing their infection status were 48.7% (167/343), 4.2% (7/165), 9.9% (15/151) and 0.0% (0/3), respectively. The risk factors for using no condom at sex with regular sexual partners included living at Dali, being farmer, unmarried, cohabitation, divorced and widowed, monthly income under 1 000 yuan (RMB), living in urban area before infection, knowing no AIDS related knowledge etc. The risk factors for using no condom at sex with occasional sexual partners included living in Dehong, Honghe and Lincang, aged ≤ 30 years and being farmer. The injecting drug users accounted for 8.2% (37/450) and 75.5% of these cases had received AIDS related intervention (340/450). Conclusion High prevalence of heterosexual transmission of HIV, poor AIDS related knowledge on awareness, high risk behavior and poor condom use and poor intervention service utilization were found among newly detected HIV infected persons in areas with high HIV infection prevalence in Yunnan. |
