中国老年人跌倒发生率meta分析

目的对中国老年人跌倒发生率进行meta分析。方法参考Cochrane协作网工作手册检索2001-2014年相关数据库及其他网络资源的相关资料，应用加强观察性流行病学研究报告质量（strengthening the reporting of ob-servational studies in epidemiology, STROBE）为参考标准评价文献质量，对23个研究应用Stata/SE11.0软件进行meta分析，选用随机效应模型合并效应量。结果资料存在异质性（I2=93.4%），通过随机效应模型得出，老年人的跌倒发生率的合并值是18.3%（95%CL是15.7%~20.8%）。结论跌倒在老年人中的发生率较高，老年人需要警惕。

Meta-analysis of the prevalence of fall in elderly in China

Objective To make a meta analysis of the prevalence of fall in elderly Chinese population. Methods Standard search strategy for Cochrane review group was performed.

STROBE （strengthening the reporting of observational studies in epidemiology） were used to evaluate the quality of the studies. The random effects model of the meta-analysis was employed according to Stata/SE11.0 for homogeneity. Results It was considered that the the references homogenous after testing of homogeneity （I2=93.4%）, the pooled preva-lence was18.3%and the 95%confidence interval was from 15.7%to 20.8%.
