概括
较高的体重调整腰部指数 (WWI),腹部肥胖的标志物,与老年人,特别是男性的认知功能较差有关. 针对腹部肥胖的干预措施对于保持认知健康至关重要.
科学领域:
- 老年学是指老年学的学科.
- 肥胖问题研究研究
- 神经科学是一个神经科学.
背景情况:
- 肥胖对认知功能的影响是研究的一个重要领域.
- 体重调整腰部指数 (WWI) 是一种新的腹部肥胖的标志物.
- 老年人中WWI和认知表现之间的关系需要进一步调查.
研究的目的:
- 探索第一次世界大战与老年人认知表现之间的关联.
- 研究第一次世界大战和认知领域之间的线性和非线性关系.
- 检查第一次世界大战对认知功能的子组差异和预测性能.
主要方法:
- 对NHANES 2011-2014年数据的横截面分析 (共3,472名参与者).
- 多变量回归和平滑曲线适合评估第一次世界大战与认知测试 (CERAD-WL,AFT,DSST) 的关系.
- 采用了子组分析,相互作用测试和随机森林模型.
主要成果:
- 在第一次世界大战和学习/记忆 (CERAD-WL),口语流 (AFT) 和处理速度 (DSST) 的分数之间发现了显著的负相关性.
- 负面关联在男性中更明显,并且随着年龄的增长而减少.
- 观察到非线性值效应,认知衰退在较高的第一次世界大战值时加速.
结论:
- 增加的腹部肥胖 (更高的WWI) 与老年人的认知缺陷有关.
- 第一次世界大战与认知关系的性别特异性需要量身定制的干预措施.
- 针对腹部肥胖症对于维持老年人群的认知功能很重要.

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...
