Small for gestational age birth was 6.5X more likely if mother was vitamin D deficient – March 2015
Preterm birth rate reduced by vitamin D – 78 percent if non-white, 39 percent if white – July 2017
Poor motor development in infant was 40 percent more likely if low maternal vitamin D – July 2017
50,000 IU of vitamin D for 8 weeks of pregnancy raised most above 30 nanograms - RCT Jan 2017

Objective To determine whether maternal vitamin D deficiency during pregnancy is associated with small for gestational age (SGA).

Methods A comprehensive literature search of PubMed, the Cochrane Library, Embase, and the Elsevier ScienceDirect library was conducted to identify relevant articles reporting prospective cohort studies in English, with the last report included published in February 2017. Pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were used to evaluate the correlation in a random effects model.

Results A total of 13 cohort studies were included in this meta-analysis with a sample of 28 285 individuals from seven countries. The pooled overall OR for babies born SGA was 1.588 (95% CI 1.138 to 2.216; p<0.01) for women with vitamin D deficiency. The prevalence of vitamin D deficiency during pregnancy varied from 13.2% to 77.3%. Subgroup analyses identified no significant differences in the association between vitamin D deficiency and SGA based on study quality, gestational week during which blood sampling was performed, cut-off vitamin D levels, sample size, adjustment for critical confounders and method for measuring vitamin D.

Conclusion This meta-analysis suggests that vitamin D deficiency is associated with an increased risk of SGA.
