目的：评价1980/2013年中国大陆地区小学生近视患病率。中国大陆人群尤其是儿童的近视眼患病率高，近视已然成为突出的公共卫生问题，而至今国内仍缺乏基于全国人群的小学生近视眼患病率的研究。

方法：系统检索万方数据库、中国(CNKI)学术文献总库和PubMed数据库相关文献，检索时间截止2013年12月31日； 两名评阅者提取纳入文献的相关信息，Meta分析采用Meta-Analyst 3.13软件。

结果：共纳入符合条件发表于1980/2013年间的文献37篇，总调查人数245 248人。纳入人群的近视眼患病率为26.5%(95%CI：21.8%～31.7%)； 近视眼患病率随年龄增长而上升(6～8岁8.4%到12～14岁57.4%)。

结论：中国大陆地区小学生近视眼患病率明显高于西方国家和地区，年龄增加近视眼患病率上升。该研究可能对大陆地区小学生近视眼防治具有参考价值。

AIM: To estimate the pooled prevalence of myopia among primary school students in mainland China during 1980-2013. Myopia had become a growing public health issue, with high prevalence rates in mainland China, particularly among children. However, we still had no population-based nationwide studies of the prevalence of myopia among primary school students in recent years.

METHODS: Wanfang, Chinese National Knowledge Infrastructure and PubMed databases were searched independently until Dec. 31, 2013 to identify relevant articles. Data from the eligible articles were extracted by two reviewers. All of the data analyses were conducted using Meta-Analyst software(version 3.13, USA).

RESULTS: Thirty-seven eligible studies published between 1980 and 2013 were selected with a total of 245 248 individuals. The pooled prevalence of myopia among the included individuals was 26.5%(95% CI: 21.8%-31.7%). The prevalence of myopia increased with age(from 8.4% at 6-8y to 57.4% at 12-14y).

CONCLUSION: The pooled prevalence of myopia among primary school students in mainland China was much higher than that of western countries or regions. The prevalence of myopia increased with age among primary school students. This study should be valuable for myopia prevention and treatment in mainland China.
