[PMID: 33494857 PMCID: PMC8524427 DOI: 10.1017/s0007114521000301] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 01/07/2021] [Accepted: 01/18/2021] [Indexed: 01/09/2023]
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/d up to the age of 2 years), supplementation at the ages of 5 and 7 years, and serum 25-hydroxyvitamin D (s-25(OH)D) at various time points associated with bone mineral density (BMD) at the age of 7 years in the Odense Child Cohort, Denmark (n 1194). High adherence was defined as supplementation with 10 µg of vitamin D 6-7 times per week during ≥80 % of the observation time. s-25(OH)D was analysed using LC-MS/MS. Total-body-less-head (TBLH) BMD was measured by dual-energy X-ray absorptiometry. At the median age of 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 TBLH BMD at the median age of 7·1 years was 0·613 (SD 0·049) g/cm2 (z-score +0·363 (SD 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 the age of 7 years.

The Effects of Vitamin D Supplementation During Infancy on Growth During the First 2 Years of Life. J Clin Endocrinol Metab 2021; 106:e1140-e1155. [PMID: 33347567 DOI: 10.1210/clinem/dgaa943] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Indexed: 02/06/2023]
Abstract
CONTEXT The relationship between maternal and infant vitamin D and early childhood growth remains inadequately understood. OBJECTIVE This work aimed to investigate how maternal and child 25-hydroxyvitamin D (25[OH]D) and vitamin D supplementation affect growth during the first 2 years of life. METHODS A randomized, double-blinded, single-center intervention study was conducted from pregnancy until offspring age 2 years. Altogether 812 term-born children with complete data were recruited at a maternity hospital. Children received daily vitamin D3 supplementation of 10 μg (group 10) or 30 μg (group 30) from age 2 weeks to 2 years. Anthropometry and growth rate were measured at age 1 and 2 years. RESULTS Toddlers born to mothers with pregnancy 25(OH)D greater than 125 nmol/L were at 2 years lighter and thinner than the reference group with 25(OH)D of 50 to 74.9 nmol/L (P < .010). Mean 2-year 25(OH)D concentrations were 87 nmol/L in group 10 and 118 nmol/L in group 30 (P < .001). When group 30 was compared with group 10, difference in body size was not statistically significant (P > .053), but group 30 had slower growth in length and head circumference between 6 months and 1 year (P < .047), and more rapid growth in weight and length-adjusted weight between 1 and 2 years (P < .043). Toddlers in the highest quartile of 25(OH)D (> 121 nmol/L) were shorter (mean difference 0.2 SD score [SDS], P = .021), lighter (mean difference 0.4 SDS, P = .001), and thinner (in length-adjusted weight) (mean difference 0.4 SDS, P = .003) compared with the lowest quartile (< 81.2 nmol/L). CONCLUSION Vitamin D and early childhood growth may have an inverse U-shaped relationship.

J Clin Endocrinol Metab 2020; 105:5686159. [PMID: 31872219 PMCID: PMC7065842 DOI: 10.1210/clinem/dgz299] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Accepted: 12/19/2019] [Indexed: 01/04/2023]
Abstract
CONTEXT Vitamin D (VD) deficiency in pregnancy and the neonatal period has impacts on childhood outcomes. Maternal VD sufficiency is crucial for sufficiency in the neonate, though the effect of early versus late pregnancy 25-hydroxy-vitamin D (25(OH)D) levels on neonatal levels is unknown. Furthermore, chemiluminescence immunoassays (CLIAs) are widely used, though their validity in measuring 25(OH)D specifically in cord blood specimens has not been established. OBJECTIVE To assess the validity of a CLIA in the measurement of cord blood 25(OH)D and to evaluate maternal determinants of neonatal 25(OH)D, including early versus late pregnancy 25(OH)D levels. DESIGN This is an ancillary analysis from the Vitamin D Antenatal Asthma Reduction Trial (VDAART), a randomized, double-blinded, placebo-controlled study. PARTICIPANTS AND INTERVENTION A total of 881 pregnant women at high risk of having offspring asthma were randomized to receive VD supplementation or placebo. Serum samples were collected from mothers in early and late pregnancy and from offspring cord blood at birth. 25(OH)D levels were assayed by CLIA in all maternal and offspring samples and by LC-MS/MS in all offspring samples and a subset of 200 maternal third trimester samples. RESULTS Cord blood 25(OH)D levels were higher as measured by CLIA (mean 37.13 ng/mL [SD 18.30]) than by LC-MS/MS (mean 23.54 ng/mL [SD 11.99]), with a mean positive bias of 13.54 ng/mL (SD 12.92) by Bland-Altman analysis. This positive bias in measurement by CLIA was not observed in maternal samples. Third trimester 25(OH)D was a positive determinant of neonatal 25(OH)D levels. CONCLUSION Chemiluminescence immunoassays overestimate 25(OH)D levels in human cord blood samples, an effect not observed in maternal blood samples. The quantification of 25(OH)D by CLIA should therefore not be considered valid when assayed in cord blood samples. Third trimester, but not first trimester, maternal 25(OH)D is one of several determinants of neonatal 25(OH)D status.

Pregnancy or cord 25-hydroxyvitamin D is not associated with measures of body fat or adiposity in children from three months to three years of age. An Odense Child Cohort study. Clin Nutr 2019; 39:1832-1839. [PMID: 31471164 DOI: 10.1016/j.clnu.2019.07.023] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Revised: 07/09/2019] [Accepted: 07/25/2019] [Indexed: 01/13/2023]
Abstract
BACKGROUND & AIMS The susceptibility to overweight in adults born during winter season may suggest foetal programming of prenatal vitamin D levels on adiposity. We investigated whether cord or pregnancy serum 25-hydroxyvitamin D (s-25OHD) was associated with infant and child body fat measures in a Danish population-based prospective cohort. METHODS In the Odense Child Cohort, 1905 singletons had cord s-25OHD and data on waist circumference (WC), weight, body mass index (BMI), and sum of skin folds (SSF) at median 3.7 months, 18.9 months and three years' age. Early and late pregnancy samples of s-25OHD (mean gestational age 12 and 29 weeks) were chosen as secondary exposures. Multiple linear and logistic regression as well as linear mixed models was applied testing the relation between cord and pregnancy s-25OHD and body fat outcomes and their Z-scores by use of updated national reference populations. Models were adjusted for maternal educational level, maternal ethnicity, pre-gestational BMI and season of birth, a priori stratified by sex. RESULTS The median [IQR] cord s-25OHD was 45.5 [31.1; 60.9] nmol/L. Cord s-25OHD <50 nmol/L was found in 57.5%; values < 25 nmol/L in 16.3%. The mean Z-scores of body fat measures at all ages were in the range of -0.32 to +0.42. No consistent associations were found between s-25OHD in cord, early pregnancy or late pregnancy and WC, weight, BMI, SSF, or their Z-scores at ages 3.7 months, 18.9 months, or 3 years. Neither did a computed composite outcome (WC, SSF, BMI, or weight >90th vs. ≤90 percentile) associate with cord or pregnancy s-25OHD. CONCLUSION Cord or pregnancy s-25OHD was not associated with measures of body fat or adiposity in children up to three years of age. Our data suggested no programming effect of maternal s-25OHD on offspring obesity in a relatively lean and healthy population of mothers.

Abstract
AIM Previous studies have found high rates of stunted linear growth in Greenlandic children. We measured growth patterns in Greenland and compared them with international growth charts. METHODS The study cohort comprised 279 healthy children aged 6-10 years in 2012. They participated in two pregnancy and birth cohorts in Greenland and longitudinal growth data as birth was extracted from their medical records. Growth reference ranges were estimated with the lambda-mu-sigma (LMS) method and compared with growth charts from Denmark and the World Health Organization (WHO). RESULTS The children's mean length, weight and head circumference were significantly larger than the WHO growth charts (p < 0.001). We found that 21-28% of the children aged zero to one years exceeded the WHO growth chart for length by more than two standard deviations. For weight and head circumference, 9-16% of the children aged 0-10 years and 9-11% of the children from zero to two years exceeded the WHO charts by more than two standard deviations. The Danish references were exceeded to a lesser degree. CONCLUSION This study showed that the growth of Greenlandic children up to 10 years was no longer stunted. Major determining factors suggested are genetic admixture, maternal overweight, changes in nutrition and improved health.
