中国社区老年人贫血患病率的Meta分析

The Prevalence of Anemia among Elderly People in Chinese Communities: A Meta-Analysis

摘要: 目的：系统评价我国社区老年人群贫血的患病率。方法：系统检索PubMed、Embase、Cochrane Library、Web of science等英文数据库及中国知网、万方、维普等中文数据库，采用主题词与自由词结合的形式检索有关中国社区老年人贫血患病率的研究，检索时限为2021年1月至2022年2月，研究类型包括横断面研究、病例对照研究和队列研究。由两位研究员独立进行文献筛选、文献质量评价和资料提取。采用Stata16软件对我国社区老年人的贫血患病率进行Meta分析。结果纳入18篇文献，包括10篇英文文献和8篇中文文献，共162,401名社区老人。结果显示，中国社区老年人贫血总患病率为16.0% (95%CI: 13.0%~19.1%)。亚组分析结果显示，中国社区老年女性贫血患病率为17.1% (95%CI: 13.7%~20.4%)，老年男性为14.9% (95%CI: 11.5%~18.4%)。城市地区老年人贫血患病率为14.3% (95%CI: 11.2%~17.3%)，农村地区为18.7% (95%CI: 15.2%~22.3%)。60~69岁、70~79岁和80岁以上老年人贫血患病率分别为11.2% (95%CI: 7.2%~15.2%)、16.3% (95%CI: 10.2%~22.4%)、34.6% (95%CI: 26.0%~43.2%)。结论：中国社区老年人贫血患病率较高，呈女性高于男性、农村高于城市、随年龄递增的特点，建议鼓励老年人定期体检，及早发现和治疗贫血，降低贫血患病率。

Abstract: Objective: To systematically estimate the prevalence of anemia among the elderly in Chinese communities. Methods: We searched PubMed, Embase, Cochrane Library, Web of science and other English databases and CNKI, Wanfang, VIP and other Chinese databases for studies on the prevalence of anemia among the elderly in Chinese communities in the form of a combination of subject words and free words from January 2021 to February 2022. The types of studies included cross-sectional studies, case-control studies, and cohort studies. Two researchers independently conducted literature screening, literature quality evaluation and data extraction. The prevalence of anemia among the elderly in Chinese communities was analyzed by stata16 software. Results: A total of 162,401 community elderly people were included in 18 literatures, including 10 English literatures and 8 Chinese literatures. The results showed that the total prevalence of anemia among elderly people in Chinese communities was 16.0% (95%CI: 13.0%~19.1%). Subgroup analysis showed that the prevalence of anemia in elderly women and elderly men in Chinese communities was 17.1% (95%CI: 13.7%~20.4%) and 14.9% (95%CI: 11.5%~18.4%). The prevalence of anemia among elderly people areas was 14.3% (95%CI: 11.2%~17.3%) in urban areas, and 18.7% (95%CI: 15.2%~22.3%) in rural areas. The prevalence rates of 60~69 years old, 70~79 years old and over 80 years old were 11.2% (95%CI: 7.2%~15.2%), 16.3% (95%CI: 10.2%~22.4%) and 34.6% (95%CI: 26.0%~43.2%) respectively. Conclusion: The prevalence of anemia among the elderly in Chinese communities is high, which is higher in women than men, higher in rural areas than in cities, and increasing with age. It is suggested to encourage elderly people to have regular physical examination, detect and treat anemia as soon as possible, and reduce the prevalence of anemia.
