中国青少年近视患病率的Meta分析

A meta-analysis for prevalence of myopia among Chinese teenagers

目的：分析1989～2014年我国青少年近视的患病率。方法通过检索中国知网、万方数据、维普数据库和PubMed数据库，获取中国青少年近视的流行病学资料，用R 3．2．3 for Windows对患病率进行Meta分析。结果有18项研究被纳入，Meta分析结果显示我国青少年近视患病率为38．37％（95％ CI＝29．06％～48．61％）。亚组分析结果显示，北方、南方、西部地区合并患病率分别为29．77％、40.00％、42．75％。2001～2007年、2008～2014年合并患病率为40.55％和36．23％。小学、初中和高中的合并患病率分别为22．53％、51．07％和65．44％。轻度、中度和重度近视合并患病率分别为24．75％、12．60％和2．39％。结论我国高中生的近视患病率较高，轻度近视是青少年近视的主要患病类型，防治近视，刻不容缓。

Objective To analyze the prevalence of myopia among Chinese teenagers born between 1989 and 2014.Methods The epidemiology data were collected by searching the database of CNKI, Wanfang, VIP and PubMed. R 3.2.3 for Windows were used for meta-analysis.Results Eighteen studies were included in the meta-analysis and the pooled myopia prevalence was 38.37%（95%CI=29.06%~48.61%）.The outcome of subgroup analysis showed that the prevalence was 29.77%, 40.00%, and 42.75%for northern China, southern China and western China, respectively. In the period from 2001~2007 the prevalence was 40.55%, and from 2008~2014, it was 36.23%.The prevalence was 22.53%, 51.07%and 65.44%among primary school, junior high school and senior high school students, respectively. For low, moderate and high myopia, the prevalence was 24.75%, 12.60%and 2.39%.Conclusions The prevalence of myopia among high school students is high, and the majority of it is low myopia.The prevention and treatment strategy of myopia is urgently needed.
