中国老年人群艾滋病知识知晓率的Meta分析

Meta-analysis on HIV/AIDS knowledge awareness rate in the elderly in China

目的更新中国老年人群艾滋病知识知晓率系统评价结果,分析时间、地区和人群分布特征。方法检索CNKI、SinoMed、WangFang Data、VIP、Web of Science、PubMed、Embase、Elsevier ScienceDirect和The Cochrane Library数据库中国老年人群艾滋病知识知晓率文献,时限均为2018年1月1日至2023年9月30日。由2位研究者独立筛选文献、评价质量,并提取信息,采用R 4.3.1软件进行Meta分析。结果共纳入26项研究包含中国老年人群25905人。Meta分析结果显示,中国老年人群艾滋病知识知晓率为51.95%(95%CI:43.31%~60.53%)。时间分布显示,2015-2021年中国老年人群艾滋病知识知晓率上升缓慢,2019年与2021年出现下降。亚组分析结果显示,西南地区、70岁及以上、小学及以下文化程度和农村地区老年人群知晓率更低,老年高危人群和使用非概率抽样的研究知晓率更高。结论我国老年人群艾滋病知识知晓率偏低,“十三五”以来知晓率增长缓慢,未得到有效提升。西南地区、高龄、低文化程度、农村地区和高危老年人群的艾滋病健康教育工作应持续加强。受纳入研究质量与数量限制,上述结论尚需更多高质量文献予以验证。

Objective To update the results of a systematic review on the HIV/AIDS knowledge awareness rate among the elderly in China,and to analyze the characteristics of its temporal,regional,and demographic distribution.Methods A literature search was conducted to select articles on AIDS knowledge awareness among the elderly in China from databases including CNKI,SinoMed,WangFang Data,VIP,Web of Science,PubMed,Embase,Elsevier Science Direct,and The Cochrane Library,covering the period from January 1,2018,to September 30,2023.Two researchers independently screened the literature,assessed the quality,and extracted information for a meta-analysis using R 4.3.1software.Results A total of 26 studies including 25,905 elderly individuals were enrolled.The meta-analysis revealed that the HIV/AIDS knowledge awareness rate among the elderly population in China was 51.95%(95%CI:43.31%-60.53%).The temporal distribution demonstrated a gradual increase in the HIV/AIDS knowledge awareness rate from 2015 to 2021,with declines observed in 2019 and 2021.Subgroup analysis indicated awareness rates were lower among the elderly population in the southwest region,those aged 70 years and above,individuals with primary school education or below,and residents in rural areas.Conversely,higher awareness rates were observed among high-risk elderly groups and studies utilizing non-probability sampling methods.Conclusions The HIV/AIDS knowledge awareness rate among the elderly population in China is relatively low,with slow growth since the"13th Five-Year Plan"period,indicating that effective improvements have not been achieved.Health education efforts concerning HIV/AIDS should be continuously strengthened for the elderly population in southwest regions,those of advanced age,with low educational levels,residing in rural areas,and within high-risk groups.Due to limitations in the quality and quantity of the included studies,the aforementioned conclusions need to be further validated by additional high-quality literature.
