户外活动时长与预防儿童近视的 Meta 分析

查看全文

目的系统评价户外活动预防儿童近视的效果,为儿童近视防控提供依据。方法计算机检索 PubMed、MEDLINE、EMbase、CNKI 和 WanFang Data 数据库,搜索户外活动对儿童近视发病率关系的研究,检索时限为建库至 2017 年 10 月。由 2 位研究员独立筛选文献、提取资料并评价纳入研究的偏倚风险后,采用 RevMan 5.3 软件进行 Meta 分析。结果共纳入 10 个研究,包括 24 667 例研究对象。Meta 分析结果显示,与对照组相比,增加户外活动组的儿童近视发病率更低[OR=0.67,95%CI(0.55,0.81),P<0.000 1]。结论当前证据显示户外活动对降低眼儿童近视的发生有一定作用。受纳入研究数量和质量限制,上述结论尚待开展更多高质量研究予以验证。

ObjectiveTo systematically review the effectiveness of outdoor activities in preventing myopia progression, and to provide scientific evidence for myopia prevention and management.MethodsPubMed, MEDLINE, EMbase, CNKI and WanFang Data databases were searched from establishment to October 2017. Two researchers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software.ResultsA total of 10 studies involving 24 667 participants were included. The results of meta-analysis showed that the incidence of myopia in outdoor activities group was lower than that in control group (OR=0.67, 95%CI 0.55 to 0.81, P<0.000 1).ConclusionThe current evidence shows that outdoor activities have protective effects on emmetropia children myopia onset. Due to the limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusions.
