目的了解东莞市无偿献血HIV感染流行趋势及人群特征,为安全输血和献血招募提供依据。方法分析2008-2012年东莞市无偿献血者121例HIV抗体阳性情况,利用SPSS16.0软件进行统计分析。结果2008-2012年东莞市无偿献血者中HIV感染率分别为15/10万、21/10万、32/10万、45/10万和51/10万,平均感染率为34/10万,各年间比较差异有统计学意义(χ2=19.89,P<0.05)。男性感染率为44/10万,女性感染率为9/10万,男性高于女性(χ2=27.31,P<0.05)。36~岁组感染率为49/10万,为各年龄组最高(χ2=12.94,P<0.05)。初中以下学历感染率为43/10万,与高中/中专组比较差异有统计学意义(χ2=4.47,P<0.05)。再次献血者感染率低于首次献血者(χ2=17.47,P<0.05)。集体组织献血与个人献血差异无统计学意义(χ2=2.84,P>0.05)。结论东莞市无偿献血者HIV感染率呈逐年上升趋势,HIV感染已从高危人群向一般人群扩散。采供血机构在严格进行抗-HIV筛查时,还应加强献血者特别是低学历青壮年男性的献血前健康征询。
Objective To understand the HIV prevalence and population characteristics of voluntary blood donation in Dongguan City and provide evidence for safe blood transfusion and blood donation. Methods The HIV-positive cases of 121 HIV-positive donors in Dongguan from 2008 to 2012 were analyzed by SPSS16.0 software.

The average infection rate was 34/10, The difference between each year was statistically significant (χ2 = 19.89, P <0.05). The prevalence was 44/10 in men and 9/10 in women, and was higher in males than in females (χ2 = 27.31, P <0.05). The infection rate of 36 ~ group was 49/10 million, which was the highest in all age groups (χ2 = 12.94, P <0.05). The infection rate of junior high school education was 43/10, with statistical significance (χ2 = 4.47, P <0.05). The rate of re-donation was lower than that of the first donors (χ2 = 17.47, P <0.05). Collective blood donation and personal blood donation difference was not statistically significant (χ2 = 2.84, P> 0.05). Conclusion The prevalence of HIV infection in unpaid blood donors in Dongguan City has been increasing year by year. HIV infection has spread from the high-risk population to the general population. Blood collection agencies in strict anti-HIV screening, but also to strengthen blood donors, especially young men with low qualifications before blood donation health consultation.
