[目的]了解安徽省既往有偿献血人员艾滋病相关知识和行为现状。[方法]采取整群随机抽样的方法，抽取安徽省既往有偿献血人群较集中的乡镇，由当地卫生专业人员担当访问员，用结构化的问卷，以入户调查的形式进行调查。[结果]调查有效问卷共1360份，应答率为98．2％。艾滋病相关知识总体知晓率为79．6％，其中对非传播途径、传播途径和防治知识的知晓率分别为84．9％，84．6％和75．3％，男性好于女性（x^2=168．844，P〈0．01）；知识获取途径前3位依次为电视（93．3％）、收音机（56．6％）和家人（52．4％）。献血时间大多为1～3年（91．6％），以单采血浆为主（65．0％），混合献血导致的感染率最高（26．8％）；安全套使用情况男性好于女性（x^2=7．718，P〈0．05），HIV阳性人群好于阴性人群（x^2=146．313，P〈0．01）；接受采血者1350人（98．5％），HIV检测结果阳性者91人（6．8％）。[结论]虽然艾滋病示范区有偿献血员的艾滋病知识掌握情况较好，但仍需加强对其（尤其是女性和中老年）艾滋病预防知识的宣传教育和安全套促进工作。

英文摘要：

[ Objective] To explore the status quo of HIV/AIDS-related knowledge and behaviors among former paid blood donors （FPBDs） in Anhui province. [Methods] With cluster sampling, FPBDs were interviewed by trained local CDC staff using structured questionnaire. [Results] A total of 1360 FPBDs were interviewed and 79.6% of their responses to HIV/ AIDS-related knowledge questions were correct. The percentage of their correct answers about non-transmission routes, transmission and prevention methods was 84.9%, 84.6% and 75.3%, respectively. Male respondents were better edacated than female ones in this regard （x^2= 168.844, P〈 0.01） . The top three sources of aquiring HIV information were TV （93.3%）, radio （56.6%） and family members （52.4%） . Most （96.1%） of the FPBDs had been involved in paid blood donation for one to three years. Paid blood （plasma） donation was the main form. The FPBDs experienced both plasma and whole blood donation were found with the highest HIV infection rate （26.8%） . Male of FPBDs used condoms more frequently than female （x^2 = 7.718, P 〈 0.05） .Condoms utilization rate was higher among HIV positive FPBDs than the negatives （x^2 = 146.313, P 〈 0.01） . Of the 1 350 FPBDs, 6.8% were tested HIV positive. [Conclusions] Although FPBDs in rural Anhui are well educated about the HIV/AIDS-related knowledge, propagandizing knowledge about prevention measures and advocating condom use should be strengthed, especially for female and elder FPBDs.
