This systematic review and meta-analysis aims to compare the effect of High-Glycemic Index (GI) versus Low-GI breakfasts on cognitive functions, including memory and attention, of children and adolescents. We systematically searched the MEDLINE (via PubMed), EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Web of Science databases, from their inception until June 2019. Articles comparing the effect of Low-GI versus High-GI breakfasts on the cognitive function (i.e., immediate memory, delayed memory, and attention) of children and adolescents were included. The DerSimonian and Laird method was used to compute the pooled effect sizes (ESs) and their respective 95% confidence intervals (CIs). The pooled ESs were 0.13 (95% CI: -0.11, 0.37) for immediate memory and 0.07 (95% CI: -0.15, 0.28) for delayed memory. For attention, the pooled ES was -0.01 (95% CI: -0.27, 0.26). In summary, GI breakfasts do not affect cognitive domains in children and adolescents.
本系统评价和荟萃分析旨在比较高血糖指数 (GI) 与低血糖指数 (GI) 早餐对儿童和青少年认知功能（包括记忆力和注意力）的影响。我们系统地检索了 MEDLINE（通过 PubMed）、EMBASE、Cochrane 对照试验中心注册库、Cochrane 系统评价数据库和 Web of Science 数据库，检索时间从建库至 2019 年 6 月。纳入比较低血糖指数与高血糖指数早餐对儿童和青少年认知功能（即时记忆、延迟记忆和注意力）影响的文章。采用 DerSimonian 和 Laird 方法计算合并效应大小 (ES) 及其各自的 95%置信区间 (CI)。即时记忆的合并 ES 为 0.13（95%CI：-0.11，0.37），延迟记忆的合并 ES 为 0.07（95%CI：-0.15，0.28）。对于注意力，合并 ES 为 -0.01（95%CI：-0.27，0.26）。综上所述，血糖指数早餐不会影响儿童和青少年的认知领域。
