Background/objectives
Vitamin D deficiency during pregnancy may influence adverse outcomes in offspring. The aim of this systematic review and meta-analysis of observational studies was to assess the association between low prenatal concentrations of 25(OH)D (by using three different cut-off levels), preterm birth (PTB) and anthropometric and neurodevelopmental outcomes in offspring.Subjects/methods
Studies reporting data on the association between maternal vitamin D concentrations and offspring outcomes identified through a systematic review of scientific literature published in PubMed/MEDLINE, Scopus and the Cochrane Library databases up to April 2017.Results
We included 54 eligible studies. Vitamin D-deficient mothers (<30 nmol/L) had offspring with *lower birthweight (MD −87.82 g; 95% CI −119.73, −55.91 g),- (smaller) head circumference (MD −0.19 cm; 95% CI −0.32, −0.06 cm) and a
- higher risk of small for gestational age (SGA) infants and
- PTB (OR 1.59; 95% CI 1.24, 2.03)
compared to mothers with concentrations ≥30 nmol/L.
Vitamin D insufficiency (<50 nmol/L) was associated with a
- higher risk of SGA (OR 1.43; 95% CI 1.08, 1.91 and
higher risk of PTB OR 1.28; 95% CI 1.08, 1.52
Concentrations of 25(OH)D ≥75 nmol/L were not found to be associated with birthweight, SGA or PTB.
Offspring of vitamin D-insufficient mothers had lower scores in- mental (MD −1.12 points; 95% CI −1.82, −0.42 cm) and
- language developmental tests (MD −0.35 points; 95% CI −1.00, 0.31 cm).
Conclusion
Maternal vitamin D deficiency is associated with offspring adverse anthropometric outcomes and PTB; insufficiency with a higher risk of SGA, PTB and adverse neurodevelopmental outcomes.Pregnancies helped by Vitamin D in many ways – 27th meta-analysis Jan 2019Printer Friendly Follow this page for updates3910 visitors, last modified 25 Jan, 2019, This page is in the following categories (# of items in each category) - All items in category Infant/Child
