Background Identified DNA variants associated with serum 25-hydroxyvitamin vitamin D (25
[OH] D) concentration may provide mechanistic insights into the vitamin D metabolic …

Background Little is known about correlates of vitamin D status in Asian populations. In this
study, we established the prevalence of vitamin D sufficiency in the Murakami region …

The main aim of the study was to determine the influence of genetic factors on the serum 25-
hydroxyvitamin D response to vitamin D supplementation. The main outcome measure was …

Background and Objectives: The genetic variations of vitamin D receptor (VDR) have
revealed its association with the risk of metabolic syndrome (MetS). In Thailand, evidence of …

Vitamin D deficiency has been consistently associated with obesity. However, it is unclear
whether vitamin D deficiency is the cause or consequence of obesity. We investigated this …

Objectives The aim of this study was to determine the influence of vitamin D–binding protein
(DBP) gene polymorphisms in vitamin D metabolites before and after vitamin D …

Background Vitamin D metabolism has been associated with type 1 diabetes. Objective We
aimed to clarify the association of 25‐hydroxylase (CYP2R1) and 1α‐hydroxylase …

Background: Although vitamin D levels and underlying vitamin D receptor (VDR) genetic
polymorphisms have been linked to many common diseases including obesity, the …

The evidence for a relationship between serum vitamin D levels and nonskeletal health
outcomes is inconsistent. The validity of single or predicted measurements of 25 …

Context: Vitamin D status in the Korean population has not been adequately determined.
Objective: To investigate the vitamin D status and the prevalence of vitamin D insufficiency in …
