中国老年人缺牙检出率的Meta分析

Prevalence rate of tooth loss among the elderly in China: a meta-analysis

目的系统评价中国老年人缺牙的发生情况。方法计算机检索CNKI、VIP、CBM、WanFang Data、PubMed、EMbase和The Cochrane Library数据库,搜集关于中国老年人缺牙情况的横断面研究,检索时限均从建库至2020年12月31日。由2名研究者独立筛选文献,提取资料并评价纳入研究的偏倚风险后,采用Stata 16.0软件进行Meta分析。结果共纳入26篇文献,总样本量为17 523例。Meta分析结果显示,我国老年人的缺牙检出率为84.7%[95%CI(81.8%,87.6%)]。亚组分析结果显示,女性、75岁及以上、居住地乡村、西南地区的老年人群缺牙检出率更高。结论当前证据显示,我国老年人的缺牙检出率较高。受纳入研究数量和质量的限制,上述结论尚需更多高质量研究予以验证。

Objective To systematically review the current status of tooth loss among elderly individuals in China. Methods Databases including CNKI, VIP, CBM, WanFang Data, PubMed, EMbase, and The Cochrane Library were searched to identify studies on the current status of tooth loss in the Chinese elderly from inception to December 31 st, 2020. Two reviewers independently screened literature, extracted data, and assessed risk of bias of the included studies.Meta-analysis was then performed using Stata 16.0 software. Results A total of 26 studies with a sample size of 17 523 participants were included. The results of the meta-analysis showed that the prevalence rate of tooth loss among the Chinese elderly was 84.7%(95%CI 81.8% to 87.6%). Subgroup analysis showed that the tooth loss prevalence rates were higher in females, individuals aged over 75, and those living in rural areas or southwest China. Conclusions The current evidence shows that the prevalence rate of tooth loss among the Chinese elderly is high. Due to the quantity and quality of the included studies, the above conclusions are needed to be verified by more high-quality studies.
