咀嚼功能如咀嚼有望改变人类的认知功能,和/或还预测了改善认知功能的可能性。这项系统评价调查了咀嚼功能是否会影响老年人/年轻人的认知功能。使用PubMed和Cochrane图书馆收集了2000年1月至2022年4月以英语撰写的完整文章。目标结果是认知功能测试得分,认知处理速度(反应时间),和咀嚼功能。对于每个研究问题,两名独立审稿人进行了搜索和筛选,数据提取,质量评估,和偏见风险评估。审稿人通过讨论解决了任何分歧。从检索到的226篇文章中,此次审查中包括20名。认知功能测试得分较低的老年人咀嚼能力较低,较低的咀嚼能力,咀嚼困难,牙齿数量减少。在咀嚼功能障碍的老年人中发现认知障碍的风险增加。对于年轻人来说,与不咀嚼口香糖相比,咀嚼口香糖显着降低了认知任务的处理速度。尽管由于研究设计的原因,大多数证据都具有较低的证据水平和较高的偏倚风险,结果仍然表明,咀嚼可能是改善认知功能的一个因素。
Masticatory function such as
chewing is expected to modify human cognitive function, and/or the possibility of improving cognitive function is also predicted. This systematic
review investigated whether masticatory function affects cognitive function for older/young adults. Full articles written in English from January 2000 to April 2022 were collected using PubMed and Cochrane Library. Target outcomes were cognitive function test scores, cognitive processing speed (reaction time), and masticatory function. For each research question, two independent reviewers conducted the search and screening, data extraction, quality assessment, and risk of bias assessment. The reviewers resolved any disagreements by discussion. From 226 articles retrieved, 20 were included in this
review. Older adults with lower scores on the cognitive function test had lower masticatory performance, lower chewing ability,
chewing difficulty, and decreased number of teeth. An increased risk of cognitive impairment was found in older adults with masticatory dysfunction. For young adults, gum chewing significantly reduced the processing speed of cognitive tasks compared to no gum
chewing. Although most of the evidence included had a low level of evidence and a high risk of bias because of the research designs, the results still suggest that mastication may be a factor in improving cognitive function.
