【摘要】 目的 通过Meta分析阐述6～22岁学生的食物摄入与近视的关系。方法 检索中文文献库（中国知网数据库、万方数据库、维普资讯、中国生物医学文献数据库）和英文文献库（PubMed、Web of Science、ProQuest、ScienceDirect、Cochrane Library）中全部有关学生食物与近视研究的文献，时间范围为2002年1月1日—2022年1月1日，筛选出符合条件的有效文献，使用Review Manager 5.4软件进行Meta分析，计算OR值以及95%CI，对食物与近视的关系进行系统化评价。结果 共纳入中文文献11篇，研究对象15 304人。各种食物摄入与6～22岁学生近视关系的合并效应值分别为：经常食用蔬菜（OR=0.41,95%CI[0.28,0.61]）；经常食用水果（OR=0.76,95%CI[0.68,0.85]）；经常食用奶类（OR=0.70,95%CI[0.50,0.99]）。结论 经常食用蔬菜、水果、奶类食物可保护视力。更多还原

【Abstract】 Objective To learn the relationship between food intake and myopia in students aged 6 to 22 years by meta-analysis.Methods The works of literature were searched from the Chinese literature databases(CNKI database, Wanfang database, VIP Information, Chinese biomedical literature database) and the foreign databases(PubMed, Web of Science,ProQuest, ScienceDirect, Cochrane Library) which were about the relationship between food intake and myopia in students.The period of the works of literature was from January 1, 2002, to January 1, 2022. The effective works of literature were screened according to the criteria. Meta-analysis was performed with Review Manager 5.4 software, and the OR value and 95%CI were calculated to systematically evaluate the relationship between food intake and myopia in students.Results A total of 11 Chinese works of literature were included,involving 15 304 persons. The combined effect values of all kinds of food intake and myopia in 6 to 22 years old students were:OR =0.41(95%CI[0.28,0.61])for regular consumption of vegetables;OR =0.76(95%CI[0.68,0.85])for regular consumption of fruit;OR = 0.70(95%CI[0.50,0.99])for regular consumption of dairy products.Conclusion Regular consumption of vegetables, fruits, and milk may be helpful to prevent myopia in students.更多还原
