目的 在控制有氧健身和体重状况的同时，研究青春期前儿童认知控制与代谢综合征 (MetS) 危险因素之间的关系。方法对二年级和三年级儿童样本 (n = 139) 进行分层回归分析，使用有氧健身、人口统计学和 MetS 危险因素变量，这些儿童执行了改良版的侧翼任务以评估认知能力 控制。还比较了不符合 MetS 危险因素标准的儿童 (n= 70) 和满足 1 个或更多标准的儿童 (n= 69) 的侧翼表现。结果回归分析表明，在控制人口统计变量和健康度后，HDL 胆固醇与侧翼反应时间 (RT) 表现出独立的负相关。组间比较进一步显示，没有危险因素的儿童的 RT 总体较短。此外，对于需要上调认知控制来满足更高的任务要求的侧卫任务的更困难条件，高危儿童表现出更大的准确性干扰分数（即表现较差）。结论这些发现与之前报道有氧健身对认知控制有益影响的文献一致，并揭示了新的证据，表明没有 MetS 危险因素的儿童比没有 MetS 危险因素的儿童表现出更好的抑制控制和更高的认知灵活性。 有风险的儿童。除了有氧健身之外，这些风险因素还可以作为重要的生物标志物，用于了解年轻一代 MetS 风险的潜在认知影响。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）
ObjectiveTo investigate the relationship between cognitive control and metabolic syndrome (MetS) risk factors in preadolescent children while controlling for aerobic fitness and weight status.MethodsHierarchical regression analyses were conducted using aerobic fitness, demographic, and MetS risk-factor variables in a sample of 2nd-and 3rd-grade children (n= 139) who performed a modified version of a flanker task to assess cognitive control. Flanker performance was also compared between children that met no MetS risk-factor criteria (n= 70), and children who met 1 criterion or more (n= 69).ResultsRegression analyses indicated that after controlling for demographic variables and fitness, HDL cholesterol exhibited an independent negative association with flanker reaction time (RT). Group comparisons further revealed that children with no risk factors demonstrated overall shorter RT than the at-risk group. In addition, at-risk children exhibited larger accuracy-interference scores (ie, poorer performance) for the more difficult conditions of the flanker task that required the up-regulation of cognitive control to meet elevated task demands.ConclusionsThese findings are consonant with the previous literature reporting a beneficial influence of aerobic fitness on cognitive control, and reveal new evidence that children without risk factors for MetS exhibit better inhibitory control and increased cognitive flexibility than do at-risk children. In addition to aerobic fitness, these risk factors may serve as important biomarkers for understanding the potential cognitive implications of MetS risk in younger generations.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
