12个既往有偿献血村艾滋病病毒传播潜在危险性综合评价

目的了解12个既往有偿献血村艾滋病病毒（HIV）传播潜在危险性。方法选择12个村的HIV感染率、丙型肝炎病毒感染率、献血（浆）员比例、艾滋病知识、性乱行为发生情况和既往病例报告数等7个指标，运用秩和比法（RSR）对各村HIV传播潜在危险性进行综合评价。结果根据专家评价，HIV感染率权重系数最高（0.28），艾滋病知识回答正确率权重系数最低（0．09）；RSR综合评价结果为：01和02号村发生HIV传播的潜在危险性较大，03、05、09、10和12号村属于中等，04、06、07、08和11号村发生HIV传播的潜在危险性较低。结论12个既往有偿献血村HIV传播潜在危险性不同，应根据分类指导的原则采取不同的艾滋病防治措施。

Comprehensive evaluation on the potential risk for HIV infection in 12 villages with a history of former paid blood donation

OBJECTIVE: To learn the potential risk for human immunodeficiency virus (HIV) infection in 12 villages with a history of former paid blood donation, and to provide different measures for HIV/AIDS prevention and control. METHODS: Seven indexes were selected, including HIV sero-prevalence rates, hepatitis C virus (HCV) sero-prevalence rates, HIV/AIDS KAB (knowledge, attitude and belief), proportion of paid blood/plasma donation, risks on related behavioral information on sex and HIV/AIDS infections. Rank Sum Ratio (RSR) was performed to synthetically evaluate the potential risk of HIV infection in those 12 selected villages. RESULTS: According to the results of evaluation by 18 experts, weight coefficient of HIV sero-prevalence rate was the highest (0.28), and HIV/AIDS KAB the lowest (0.09) among the seven indexes. The results of comprehensive evaluation with RSR showed that the villages coded 01 and 02 belonged to higher level of potential risk of HIV infection, villages 09, 12, 05, 10 and 03 were at medium level while villages 04, 06, 08, 07 and 11 were at low level. CONCLUSION: The level of potential risk for HIV infection was different in 12 villages with a history of former paid blood donation. Different measures of HIV/AIDS prevision and control should be performed according to the potential risk level for HIV infection of the 12 villages.
