目的了解云南省边境县(市、区)出境务工人群艾滋病知识知晓水平、高危行为及HIV感染状况,为制定出境务工人员干预策略提供依据。方法采用整群抽样的方法,对云南省边境地区的返乡出境务工人群进行横断面调查。结果调查对象8 867例,HIV感染率为0.2%。与配偶或固定性伴、临时性伴和商业性伴最近1次发生性行为时使用安全套比例(2=664.85,P<0.001)和最近1年发生性行为时每次使用安全套比例(2=1 044.43,P<0.001)差异有统计学意义。多因素Logistic分析显示,出境务工时间和有无临时/商业性伴为HIV感染危险因素,最近1次安全套使用率为HIV感染保护因素。结论应重点加强云南省尤其是边境地区出境务工人群的艾滋病宣传教育和行为干预工作,探索科学长效的艾滋病综合干预机制。
Objective To understand the level of AIDS knowledge, high-risk behaviors and HIV infection in outbound migrant workers in Yunnan border counties (cities and districts), and provide the basis for formulating intervention strategies for migrant workers. Methods A cluster sampling method was used to carry out a cross-sectional survey of returning migrant workers in the border areas of Yunnan Province. Results A total of 8 867 subjects were surveyed, with an HIV prevalence of 0.2%. Condom use ( 2 = 664.85, P <0.001) for the most recent sexual intercourse with spouse or spouse, adolescent partners and business partners and the proportion of condom use at each sexual intercourse during the last year (2 = 1 044.43, P <0.001) The difference was statistically significant. Multivariate Logistic analysis showed that the time spent on leaving the country and the presence / absence of temporary / commercial partners were risk factors for HIV infection. The most recent condom use rate was HIV infection protection factor. Conclusions Should focus on strengthening AIDS outreach education and behavior intervention work outbound migrant workers in Yunnan Province, and explore scientific long-term AIDS comprehensive intervention mechanism.
