安徽省青年学生艾滋病知识行为调查及血清学检测分析

Survey on the knowledge and behavior of AIDS and serological analysis among young students in Anhui Province

目的了解青年学生人群的艾滋病知识行为及艾滋病、梅毒、丙肝感染情况,帮助制定相关艾滋病防治措施。方法采用分阶段整群抽样,共抽取安庆和合肥青年学生1 606人,经知情同意后进行匿名自填式问卷调查和HIV、丙型肝炎病毒(hepatitis C virus,HCV)和梅毒等3项血清学检测。结果青年学生艾滋病知识知晓率为83.62%,男生知晓率高于女生,差异有统计学意义(P<0.001);不同年级知晓率差异有统计学意义(P<0.001)。有过性行为的比例为4.48%,其中安庆市1.88%,合肥市7.07%;首次性行为使用安全套比例为31.25%;在固定性伴、临时性伴及商业性伴中最近1次性行为使用安全套比例和最近1年性行为"每次使用安全套"比例均低于50%,最近1年做过艾滋病检测的比例为2.07%。血清学检测未发现HIV抗体阳性,而梅毒抗体阳性检出率为0.19%,HCV抗体阳性检出率0.31%。结论安徽省青年学生人群艾滋病知识知晓情况总体尚好,但有个别知识点知晓率较低,部分学生有不安全的性行为,且对艾滋病自我防护意识薄弱。今后需进一步加强青年学生艾滋病防治知识的宣传教育工作,同时扩大高危行为干预和检测覆盖面。

Objective To know AIDS related knowledge, behavior and infective status of HIV, hepatitis C virus （HCV） and syphilis among young students in Anhui Province, and to draw up strategies for prevention and control of AIDS. Methods Multi-stage cluster sampling method were used. 1 606 students from Anqing and Hefei were recruited to finish the self-response questionnaires anonymously and received serological tests of HIV, HCV and syphilis after obtaining informed consent. Results The awareness rate of AIDS/HIV knowledge was 83.62% in young students. The awareness rate of boys was significantly higher than girls （P 〈 0. 001 ）. The awareness rate of different grade also had significant differ- enee（P 〈 0. 001 ）. The proportion of the students reported having sex behaviors was 4. 48% , 1.88% in Anqing and 7. 07% in Hefei City respectively. The proportion of using condoms in the first sexual intercourse was 31.25%. The pro- portions of using condoms in the last time and during every sexual intercourse in the past year were lower than 50% in sex with regular sex partner, temporary sex partner or commercial sex partner. The proportion of students received the test of HIV was 2. 07% in the past year. The results of serological test showed the positive rate of syphilis and HCV were 0. 19% and 0. 31% respectively, and there was no positive report of HIV. Conclusions The overall level of the awareness rate of AIDS/HIV knowledge among young students in Anhui province is good, but for some individual knowledge, the awareness rate is low. Part of students had unsafe sexual behavior, and the awareness of protecting us from AIDS is weak. It is neces- sary to strengthen the propaganda educational work about HIV/AIDS knowledge for young students in future, and to expand high-risk behavior intervention and testing coverage.
