Rebecca J Moon 1 2, Harry D Green 3, Stefania D'Angelo 3, Keith M Godfrey 3 4, Justin H Davies 5 6, Elizabeth M Curtis 3, Cyrus Cooper 3 4 7, Nicholas C Harvey 3 4Systematic review and meta-analysis of the effect of moderate- to high-dose vitamin D supplementation in pregnancy on offspring bone mineralisation found a positive effect of vitamin D supplementation on offspring bone mineral density (BMD) at age 4-6 years, with a smaller effect on bone mineral content.
Purpose: A systematic review and meta-analysis was performed to assess the effect of pregnancy vitamin D supplementation on offspring bone mineral density (BMD) in childhood.
Methods: A literature search was conducted for published RCTs of antenatal vitamin D supplementation with assessment of offspring BMD or bone mineral content (BMC) by dual-energy X-ray absorptiometry (DXA) using MEDLINE and EMBASE up to 13th July 2022. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool. Study findings were grouped in two age groups of offspring assessment: neonatal period and early childhood (3-6 years). Random-effects meta-analysis of the effect on BMC/BMD at 3-6 years was performed using RevMan 5.4.1, yielding standardised mean difference (SMD) (95% CI).
Results: Five RCTs were identified with offspring assessment of BMD or BMC; 3250 women were randomised within these studies. Risk of bias was low in 2 studies and "of concern" in 3. Supplementation regimes and the control used (3 studies used placebo and 2 used 400 IU/day cholecalciferol) varied, but in all studies the intervention increased maternal 25-hydroxvitamin D status compared to the control group. Two trials assessing BMD in the neonatal period (total n = 690) found no difference between groups, but meta-analysis was not performed as one trial represented 96.4% of those studied at this age. Three trials assessed offspring whole-body-less-head BMD at age 4-6 years. BMD was higher in children born to mothers supplemented with vitamin D [0.16 SD (95% confidence interval 0.05, 0.27), n = 1358] with a smaller effect on BMC [0.07 SD (95% CI - 0.04, 0.19), n = 1351].
Conclusions: There are few RCTs published to address this question, and these are inconsistent in methodology and findings. However, meta-analysis of three trials suggests moderate- to high-dose vitamin D supplementation in pregnancy might increase offspring BMD in early childhood, but further trials are required to confirm this finding.
