Objective: To understand the related risk behaviors, knowledge and status of HIV/AIDS infection among rural adults of Derung minority, to provide relevant messages for the development of HIV/AIDS intervention strategy in this minority group. Methods: We used system sampling method to conduct a cross-sectional survey in 6 administration villages of Derung Township, Gongshan Derung and Nu Autonomous County in Nujiang Lisu Autonomous Prefecture of Yunnan Province, with a sample size estimated as 383. Adult residents with Derung minority in six villages of Gongshan County were involved, with relevant information collected through door-to-door visit. HIV antibody was tested and SPSS 17.0 was used for statistical analysis. Results: Information on 394 valid respondents was collected, with age as between 18 and 65 (34.39±9.74), 80.7% (318/394) as married, 54.0% (213/394) having had primary school education, 13.2% (52/394) as migrant workers. In this population, the overall HIV infection rate appeared as 0.5% (2/400), mainly through sexually transmission. The rate of awareness on HIV/AIDS was 69.8% (275/394), mainly through free publicized materials 50.0% (197/394). Rates on premarital sexual behavior on multiple sexual partners in the past year, on temporary sexual partners in the past year, having commercial sexual experiences in the past year and ever used condoms when engaging in casual sex, were 6.4% (60/366), 18.0%(66/366), 5.7%(21/366), 1.9%(7/366) and 8.0%(25/311), respectively. Conclusions: Few numbers of HIV infections were identified among the migrating workers with Derung minority, with sexual transmission as the major route, along with the increased number of rural migrant workers and the low rates both on AIDS knowledge and condom use, accompanied by the high risk sexual behavior appeared in this rural adult residents of Derung minority. Relative strategies on HIV/AIDS intervention and control should be developed.
目的： 了解云南省独龙族农村成年居民艾滋病相关行为、艾滋病知识知晓率及HIV感染现况，为制定少数民族艾滋病干预策略提供依据。 方法： 采用系统抽样，对云南省独龙族的聚居地云南省怒江傈僳族自治州贡山独龙族怒族自治县（贡山县）独龙江乡6个行政村农村成年居民进行横断面调查，并用系统抽样样本估算为383人，通过一对一入户调查并进行HIV抗体检测，收集相关信息，采用SPSS 17.0软件进行统计学分析。 结果： 共调查400人，有效问卷394份。调查对象年龄18~65（34.39±9.74）岁，已婚者占80.7%（318/394），小学以下文化程度占54.0%（213/394），外出打工者占13.2%（52/394）。HIV感染率为0.5%（2/400），均为外出打工经性传播感染。艾滋病知识知晓率为69.8%（275/394），知识来源主要是免费宣传材料50.0%（197/394）。婚前性行为发生率为6.4%（60/366）、最近1年多性伴行为发生率为18.0%（66/366）、最近1年临时性行为发生率为5.7%（21/366）、最近1年商业性行为发生率为1.9%（7/366）。最近1次性行为安全套使用率为8.0%（25/311）。 结论： 独龙族农村成年居民存在少数HIV感染者，感染原因主要是外出打工经性行为感染。独龙族农村居民近年外出打工现象增多，存在艾滋病知识知晓率不高、高危性行为发生率较高、安全套使用率较低的问题。应加强艾滋病知识教育、提高安全套使用率等干预服务。.
