Abstract：
OBJECTIVE: The aim of the present study was to synthesize the available evidence from the relationship between adherence to the Mediterranean diet (MedDiet) and academic performance in children and adolescents.
METHODS: A systematic review and meta-analysis was conducted, which adhered to the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Four electronic databases (PubMed, Scopus, Web of Science, and the Cochrane Library) were examined from inception to April 8th, 2024.
RESULTS: Eighteen studies were included in the current systematic review and sixteen in the meta-analysis. The relationship between adherence to the MedDiet and academic performance among children and adolescents was statistically significant (Pearson\'s correlation coefficient [r] = 0.17, 95% confidence interval [CI]: 0.14 to 0.21, p < 0.001; inconsistency index [I2] = 56.7%). The influence analysis revealed that removing individual studies one at a time did not result in any changes to the overall results (p < 0.05 in all cases).
CONCLUSIONS: A higher adherence to the MedDiet could play a relevant role in academic performance among children and adolescents.

摘要：
目的：本研究的目的是综合来自儿童和青少年坚持地中海饮食（MedDiet）与学业成绩之间关系的现有证据。
方法：进行了系统评价和荟萃分析，遵守系统审查和荟萃分析（PRISMA）声明的首选报告项目中概述的指南。四个电子数据库(PubMed，Scopus,WebofScience,和Cochrane图书馆）从成立到4月8日进行了检查，2024.
结果：目前的系统评价包括18项研究，荟萃分析包括16项研究。儿童和青少年对MedDiet的依从性与学习成绩之间的关系具有统计学意义（Pearson相关系数[r]=0.17，95％置信区间[CI]：0.14至0.21，p<0.001；不一致指数[I2]=56.7％）。影响分析显示，一次删除一项单独研究不会导致总体结果的任何变化（在所有情况下p<0.05）。
结论：提高对MedDiet的依从性可能对儿童和青少年的学习成绩起到相关作用。
