咖啡的消费,尤其是含咖啡因的咖啡,与较低的血清α-Klotho (SαKl) 水平有关,以L形模式. 这表明咖啡对衰老生物标志物的潜在影响.
科学领域:
- 老年学是一门学科.
- 营养科学 营养科学
- 生物化学 生物化学
背景情况:
- 咖啡消费在美国很普遍,并且与健康益处有关,例如减少脂肪.
- 阿尔法-克洛托 (α-Klotho) 是一种与衰老,寿命和保护各种疾病相关的蛋白质.
- 本研究探讨了咖啡摄入量与血清α-Klotho (SαKl) 水平之间的关系.
研究的目的:
- 为了研究总量,含咖啡因和无咖啡因咖啡摄入量与血清α-Klotho (SαKl) 水平之间的关联.
- 分析咖啡消费和SαKl.之间的剂量反应关系.
主要方法:
- 来自美国国家健康和营养检查调查 (2007-2016) 的9,811名美国成年人 (40-79岁) 的数据分析.
- 通过24小时饮食回忆评估的咖啡摄入量.
- 使用ELISA测量血清α-Klotho (SαKl) 水平;使用多变量回归和通用添加模型分析关系.
主要成果:
- 在总和含咖啡因咖啡摄入量和SαKl水平之间发现了L形关联.
- 这种模式在低咖啡消费率下急剧下降,在摄入量较高时停滞不前,特别是在女性和60岁以下的人群中.
- 脱咖啡因咖啡摄入量与SαKl水平没有显著的关联.
结论:
- 咖啡 (尤其是含咖啡因的咖啡) 摄入量和血清α-Klotho (SαKl) 水平之间存在负面的L形关联.
- 咖啡因咖啡可能会影响与衰老相关的生物标志物.
- 需要进一步的研究来阐明这种关联的潜在机制.
