Abstract Vitamin D supplementation in infancy is recommended to prevent rickets. At the population level, its effects on bone mineralisation are largely unknown. We aimed to explore whether adherence to national vitamin D supplementation guidelines (10 µg/day up to age 2 years), supplementation at ages 5 and 7 years, and serum 25-hydroxyvitamin D (s-25(OH)D) at various time points associated with bone mineral density (BMD) at age 7 years in the Odense Child Cohort, Denmark (n=1,194). High adherence was defined as supplementation with 10 µg vitamin D 6-7 times per week during ≥ 80 % of the observation time. S-25(OH)D was analysed using liquid chromatography-tandem mass spectrometry. Total-body-less-head (TBLH) BMD was measured by dual-energy X-ray absorptiometry. At median age 18.1 months, 53.9 % (n=475/881) reported high adherence. The median s-25(OH)D was 64.7, 78.8, 46.0, and 71.8 nmol/l in early pregnancy, late pregnancy, cord blood, and at 5 years, respectively. The mean (SD) TBLH BMD at median age 7.1 years was 0.613 (0.049) g/cm2 (z-score +0.363 (0.824)). In adjusted analyses, vitamin D supplementation up to 18 months, and at 5 and 7 years, was not associated with TBLH BMD. Similarly, no robust associations were found between TBLH BMD and s-25(OH)D at any time point. No associations were found for TBLH bone mineral concentration or bone area. In this population with relatively high s-25(OH)D concentrations, no consistent associations were found between adherence to vitamin D supplementation recommendations or vitamin D status in pregnancy or childhood, and bone mineralisation at age 7 years.

Abstract Background Observational studies have demonstrated associations between maternal gestational vitamin D status and offspring bone health. We have recently shown, in a randomised controlled trial, that pregnancy vitamin D supplementation leads to improved offspring bone mass at birth amongst winter deliveries (when background 25(OH)-vitamin D levels are lowest). In the present analysis, we aimed to evaluate whether the beneficial effect of pregnancy vitamin D supplementation on neonatal bone mass is sustained into early childhood, with bone indices assessed at age 4 years in a subset of participants of the MAVIDOS trial. Methods Pregnant women were randomised in Southampton, Oxford and Sheffield, in a double-blind design, to 1000 IU/day cholecalciferol or matched placebo from 14 weeks’ gestation to birth. At 4 years of age (Southampton participants only, n = 723 births), offspring assessments included anthropometry, whole-body dual-energy x-ray absorptiometry (DXA) [Hologic Horizon, yielding whole body less head (WBLH) bone mineral content (BMC), bone mineral density (BMD), bone area (BA) and lean mass (LM)], and a maternal questionnaire. Linear regression was used to estimate the mean difference (represented by β) in outcomes between the two randomisation arms, adjusted for sex and age at DXA. Further models were additionally adjusted for gestational age, maternal BMI, and child’s sedentary time. All outcomes were standardised to a standard deviation scale, for ease of comparison. Full ethics and MHRA approvals were granted. Results 564 children attended the 4-year visit; 452 had a useable DXA with minimal movement artefact. Maternal pregnancy vitamin D supplementation led to greater offspring indices of bone mass compared with placebo, irrespective of season. For example, WBLH BMD at age 4 years was greater in the offspring of supplemented mothers [β = 0.18 SD (95%CI: 0.00, 0.35), p = 0.047]; there was also evidence of greater LM in the intervention group [β = 0.15 SD (95%CI: -0.02, 0.31), p = 0.081]. In fully adjusted models associations were consistent for lumbar spine indices and for BA and BMC. In keeping with the offspring findings, maternal vitamin D supplementation led to significantly higher maternal plasma 25(OH)D concentrations in late pregnancy (34 weeks’ gestation): placebo group (median(IQR)): 42.4 nmol/l (23.3, 56.4); vitamin D group: 67.4 nmol/l (56.2, 80.3); p < 0.001. Conclusion This is the first ever demonstration in a large placebo-controlled, double-blind randomised controlled trial that maternal pregnancy vitamin D supplementation leads to improved bone and lean mass in children. Our findings suggest that maternal cholecalciferol supplementation may have lasting benefits for offspring musculoskeletal health and thus represent an important public health message.
