JCEM:老年妇女维生素D与虚弱和虚弱进展之间的关系

2019-07-10 xing.T MedSci原创

由此可见,在这项针对75岁女性的前瞻性观察社区队列研究中,维生素D不足与虚弱程度有关。该研究支持维持足够的维生素D水平以促进健康老龄化。

维生素D(25OHD)在许多生理功能中起作用,这些功能随着年龄的增长而下降,导致虚弱和负性健康结局风险增加。然而,25OHD是否可以成为长期虚弱的长期危险标志,是否与年龄增长一致尚不清楚。近日,内分泌和代谢性疾病领域权威杂志Journal of Clinical Endocrinology & Metabolism上发表了一篇研究文章,该研究旨在调查25岁以上女性25OHD与虚弱之间的关系。

该研究为来自瑞典马尔默的前瞻性、基于人群的队列研究。参与者为社区居住的年龄为75岁(±0.1)的女性(n=1044),在80岁(±0.2)(n=715)和85岁(±0.1)(n=382)时进行重新评估。研究人员使用10个变量的虚弱指数量化虚弱程度,范围从0(最低)到1(最高)。女性被归类为维生素D不足(<50nmol/L)或足够(≥50nmol/L)。 

在75岁和80岁时,25OHD不足的女性比足够25OHD的女性更虚弱(0.23 vs. 0.18; p<0.001和0.32 vs. 0.25; p=0.001)。在80岁时,25OHD不足也与随后5年后的虚弱有关(0.41 vs. 0.32; p=0.011)。有趣的是,虚弱的加速进展与较低的25OHD无关,25OHD>75nmol/L对虚弱也无益处。在85岁时未观察到25OHD与虚弱之间存在关联。在脆弱指数中,与25OHD相关的变量是与肌肉力量和功能相关的变量。

由此可见,在这项针对75岁女性的前瞻性观察社区队列研究中,维生素D不足与虚弱程度有关。该研究支持维持足够的维生素D水平以促进健康老龄化。
