随后，研究人员利用35个25-(oh)d变异基因，基于遗传因素对25-(oh)d的水平进行了计算，并记录了直至2020年6月，参与者的全因死亡和死因别死亡（特殊 ...

为探究血清 25 - 羟维生素 D（25 (OH) D）水平在挪威普通成年人群中的长期变化及影响因素，研究人员开展了 Tr?ndelag 健康研究（HUNT）。结果显示其 11 年间可靠性中等，多种因素与之相关。这表明单次测量评估维生素 D 状态不足，重复测量意义重大。

这项研究的不足是仅在单个时间点测量25(oh)d；维生素d不足的参与者人数很少，限制了在该组中检测关联的能力；很大一部分女性的维生素d水平足够 ...

1,25 dihydroxy vitamin D 3 (1,25(OH) 2 D 3) is a lipid-soluble hormone that has well-established classic function in maintaining calcium homeostasis and promoting bone mineralization. 3 In ...

Researchers have identified in a new study that increased serum 25-hydroxyvitamin D (25(OH)D) is linked with lower risks of ...

Free 25(OH)D is a stronger predictor of all-cause mortality than total 25(OH)D in older men. Free 1.25(OH)2D, the biologically active metabolite, was not predictive of all-cause mortality.

Higher vitamin D intake and serum 25(OH)D levels may provide significant benefits for cancer incidence and mortality, according to the results of a meta-meta-analysis published in Nutrients.

The test is also known as the 25-OH vitamin D test and the calcidiol 25-hydroxycholecalcifoerol test. It can be an important indicator of osteoporosis (bone weakness) and rickets (bone malformation).

In a recent study published in Nutrients, a group of researchers examined the association between 25-hydroxy-vitamin D (25(OH)D) concentrations and neurodevelopmental outcomes in 3–5-year-old ...

Higher concentrations of vitamin D, specifically serum 25-hydroxyvitamin D (25(OH)D), are associated with improved survival with chronic obstructive pulmonary disease (COPD), according to a study ...
