目的了解≥50岁艾滋病病毒(HIV)感染者艾滋病知识知晓水平和高危行为现状,为制定防制策略提供科学依据。方法采用整群抽样方法,抽取云南省4个县(区、市)中各一个疫情较重的乡镇≥50岁HIV感染者进行一对一问卷调查,样本量201人。结果调查对象的艾滋病知识知晓率为93.5%,多因素非条件Logisitic回归分析显示,影响艾滋病知识知晓的主要因素为:少数民族[比值比(OR)=0.19,95%可信区间(CI):0.05~0.78]、收入低(OR=2.37,95%CI:1.01~5.56)、初中以下文化水平(OR=0.25,95%CI:0.07~0.85)。是否喝酒(χ~2=201.00,P<0.01)和是否接受非政府组织关心(χ~2=5.56,P<0.05),艾滋病知识知晓率差异有统计学意义。结论云南省艾滋病高流行区≥50岁HIV感染者艾滋病知识知晓率较高,但个别知识点的答对率较低;社会、经济和文化是该人群艾滋病知识知晓率的影响因素,应进一步采取针对性的健康教育措施。
Objective To understand the status of HIV / AIDS knowledge and risk behaviors in people over 50 years of HIV infection and provide a scientific basis for making prevention and control strategies. Methods By cluster sampling method, a one-to-one questionnaire survey was conducted on one HIV-infected person aged 50 years or older in each of the four counties (districts and cities) in Yunnan Province. The sample size was 201. Results The rate of knowledge about AIDS among the respondents was 93.5%. The multivariate non-conditional Logistic regression analysis showed that the main factors affecting the knowledge of HIV / AIDS were ethnic minorities [odds ratio (OR) = 0.19, 95% confidence interval (CI) 0.05 ~ 0.78], low income (OR = 2.37, 95% CI: 1.01 ~ 5.56), junior high school education level (OR = 0.25,95% CI: 0.07 ~ 0.85). (Χ ~ 2 = 201.00, P <0.01), and whether they were concerned by non-governmental organizations (χ ~ 2 = 5.56, P <0.05). There was significant difference in knowledge of AIDS among students. Conclusions There is a high awareness rate of HIV / AIDS among HIV-infected persons aged 50 or above in AIDS-prevalence areas in Yunnan province, but the individual respondents have relatively low rate of correct answers. Social, economic and cultural factors are the influencing factors of HIV / AIDS awareness in this population and should be taken further Sexual health education measures.
