概括
腰与部的比率和腰与身高的比率是比成人BMI更好的认知衰退指标. 与肥胖相关的并发病完全解释了肥胖和认知之间的联系.
科学领域:
- 老年学是指老年学的学科.
- 神经科学是一个神经科学.
- 公共卫生 公共卫生
背景情况:
- 中年肥胖与认知能力下降有关,但这种联系在老年人中不一致.
- 现有的研究经常使用体重指数 (BMI),这在准确评估老年人群中的脂肪方面存在局限性.
- 许多研究重点关注特定的种族群体,并没有探索子群体的关联或使用各种脂肪度量.
研究的目的:
- 为了比较各种肥胖度量与不同人群的认知表现的关联.
- 检查年龄,性别和种族如何改变这些关联.
- 研究与肥胖相关的并发病对肥胖-认知关系的调解作用.
主要方法:
- 对来自巴西成年人健康纵向研究 (ELSA-巴西) 的12636名参与者的横截面分析.
- 使用身体质量指数 (BMI),腰与部比率 (WHR),腰与身高比率 (WHtR) 和身体脂肪百分比 (BFP) 来评估肥胖.
- 用多个测试得出的综合全球认知得分来测量认知表现;采用调整的线性回归和因果调解分析.
主要成果:
- 在10,725名参与者中,较大的WHR和WHtR与更差的全球认知表现有关.
- 这些关联并未因年龄,性别或种族而改变.
- 身体脂肪百分比 (BFP) 仅与年轻成年人的认知相关;调解分析仅显示间接影响,没有直接影响.
结论:
- 腰与部比率 (WHR) 和腰与身高比率 (WHtR) 与认知表现的相关性比BMI更为一致.
- 生物电阻分析 (BIA) 的脂肪测量仅与年轻个体的认知有关.
- 与肥胖相关的并发症完全调解了肥胖和认知功能之间的关系.

Obesity
347
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Biological Influences on Intelligence
42
Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter...
