Background and Objectives To examine the correlation between the concentration of vitamin
D (VD) in venous blood at approximately 4 weeks of age (±4 weeks of age) and neonatal …

Methods From June 1 to July 10, 2015, umbilical venous blood samples were collected from
102 full-term single neonates, and venous blood samples were collected from their mothers …

Objective To evaluate vitamin D status in very low birth weight (VLBW) infants and response
to vitamin D intake. Study design In this prospective cohort study of VLBW infants, 25 …

Background Vitamin D is essential for bone health and immune system. Vitamin D deficiency
(VDD) poses a high-risk to very preterm (VP) infants. This study aimed to evaluate the risk …

Objectives Preterm infants are at increased risk for vitamin D deficiency (VDD). We aimed to
assess the adequacy of standardized vitamin D supplementation protocol in very low birth …

Results The median level of serum 25 (OH) D was 35.9 nmol/L, and 82.7% of them were
vitamin D deficient. The serum 25 (OH) D level was lower in full-term infants compared with …

Methods A total of 600 preterm infants were enrolled, and venous blood samples were
collected within 24 hours after birth to measure the serum level of 25-hydroxyvitamin D [25 …

Purpose The primary objective of this study was to compare clinical outcomes of very low
birth weight (VLBW) infants with 25-hydroxy vitamin D [25 (OH) D] levels< 25 nmol/l in …

Objectives To evaluate vitamin D (vitD) status in early preterm infants (EPTIs) at birth and
during birth hospitalisation on current vitD intake. Design/methods Serum 25-hydroxyvitamin …

Background and Aims Based on the fact that the whole-body bone mineral content
increases between 32–33 wk and 40–41 wk gestation (3.0 fold increase), near-term infants …
