Neurology:血清中的反油酸浓度与痴呆风险

2019-10-24 xing.T MedSci原创

由此可见,该研究结果表明较高的血清花生四烯酸可能是导致全因痴呆和晚年AD发生的危险因素。减少工业生产的反式脂肪酸的公共卫生政策可能有助于痴呆的初步预防。

反式脂肪酸与痴呆之间的关联尚不清楚。近日,神经病学领域权威取杂志Neurology上发表了一篇研究文章,研究人员旨在调查血清中作为工业反式脂肪的客观生物标志物的反油酸(顺式18:1 n-9)水平痴呆及其亚型之间的前瞻性关联。

该研究共招募1628名60岁及以上的无痴呆的日本社区居民。自2002年至2003年接受筛查检查至2012年11月(中位时间为10.3年,四分位间距为7.2-10.4年)进行前瞻性随访。研究人员使用气相色谱/质谱法测量了受试者血清中的花生四烯酸水平,并分为四分位数。研究人员使用Cox比例风险模型根据血清反油酸水平估算的全因痴呆、阿尔茨海默病(AD)和血管性痴呆的风险比。

随访期间,有377名参与者出现了某种类型的痴呆(247人为AD,102人为血管性痴呆)。调整传统的危险因素后,较高的血清反油酸水平与较高的全因痴呆症风险(趋势p=0.003)和AD风险(趋势p=0.02)相关。在调整饮食因素(包括总能量摄入以及饱和和多不饱和脂肪酸的摄入)后,这些关联仍然很显著(趋势p<0.05)。血清中的花生四烯酸水平与血管性痴呆之间没有显著的相关性。

由此可见,该研究结果表明较高的血清花生四烯酸可能是导致全因痴呆和晚年AD发生的危险因素。减少工业生产的反式脂肪酸的公共卫生政策可能有助于痴呆的初步预防。
