云南省出境务工人群艾滋病感染及危险因素调查分析

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（X^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（X^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。

Analysis on the HIV/AIDS relevant risk factors of the cross-border workers in Yunnan Province

Objective To learn the HIV/AIDS basic knowledge, high risk behaviors and the HIV infection status of the cross-border workers in the border areas settled in Yunnan Province. Methods Cross-sectional surveys were con-ducted among the back home cross-border workers in the border areas settled in Yunnan Province. Results 8 867 ques-tionnaires and 8 837 blood samples were collected. The rate of basic knowledge of HIV/AIDS （60. 2% ） was low. Signifi- cant difference existed among the recent time sex condom using rate with couple or fixed sex-partner, temporary sex-partner and commerieal sex workers（CSWs） （X^2 = 664. 85 ,P 〈 0. 001 ）. In the recent year, sex condom using rate with the three population also had significant difference（ X^2 = 1 044.43 ,P 〈0. 001 ）. Multiple logistic regression analysis showed that the cross-border working time, sex with temporary sex-partner or CSWs could raise the HIV infection rate, while high condom using rate could reduce it. Conclusions More attentions should be paid on the HIV/AIDS health education and behavior intervention of the cross-border working population, and exploring the long-term HIV/AIDS comprehensive intervention mechanism.
