Associations of free, bioavailable and total 25-hydroxyvitamin D with neonatal birth anthropometry and calcium homoeostasis in mother-child pairs in a sunny Mediterranean region. Br J Nutr 2024; 131:801-808. [PMID: 37880994 PMCID: PMC10864994 DOI: 10.1017/s000711452300243x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 10/17/2023] [Accepted: 10/23/2023] [Indexed: 10/27/2023]
Abstract
Sufficient vitamin D status is crucial for successful pregnancy and fetal development. The assessment of 25-hydroxyvitamin D (25(OH)D) concentrations is commonly used to evaluate vitamin D status. Our objective was to examine the interrelated biodynamics of maternal and neonatal total, free and bioavailable 25(OH)D in maternal-neonatal dyads at birth and their associations with homeostasis and neonatal birth anthropometry. We analysed a cohort of seventy full-term mother-child pairs. We found positive associations between all neonatal measures of vitamin D status. Maternal forms exhibited a similar pattern of association, except for the bioavailable maternal form. In multivariate analysis, both total and free maternal 25(OH)D concentrations were correlated with all neonatal forms (neonatal total 25(OH)D: 1·29 (95 % CI, 1·12, 1·46) for maternal total 25(OH)D, 10·89 (8·16, 13·63) for maternal free 25(OH)D), (neonatal free 25(OH)D: 0·15 for maternal total 25(OH)D, 1·28 (95 % CI, 0·89, 1·68) for maternal free 25(OH)D) and (0·13 (95 % CI, 0·10, 0·16), 1·06 (95 % CI, 0·68, 1·43) for maternal free 25(OH)D), respectively, with the exclusion of the bioavailable maternal form. We observed no significant interactions within or between groups regarding maternal and neonatal vitamin D parameters and maternal calcium and parathyroid hormone concentrations, and neonatal birth anthropometry. Our study indicates that bioavailable maternal and neonatal 25(OH)D have no significant effects on vitamin D equilibrium, Ca homeostasis and neonatal anthropometry at birth. However, we observed an interaction between maternal and neonatal total and free 25(OH)D concentrations at the maternal-neonatal interface, with no associations observed with other calciotropic or anthropometric outcomes.

Intense Testing and Use of Vitamin D Supplements Leads to Slow Improvement in Vitamin D Adequacy Rates: A Cross-Sectional Analysis of Real-World Data. Nutrients 2023; 16:111. [PMID: 38201941 PMCID: PMC10780961 DOI: 10.3390/nu16010111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 12/11/2023] [Accepted: 12/23/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND Vitamin D testing (VDT) and supplement use (VDS) are on the rise, but most patients remain deficient (<30 ng/mL-VDD). We designed the present real-world study to assess this paradox. METHODS We reviewed data from all patients visiting our clinics between 2014 and 2022. We estimated the rate of patients with vitamin D adequacy (≥30 ng/mL) (VDA) by year and month of testing, the dose of VDS (low (≤1200 IU/day), medium (1201-3000 I/day) and high dose (>3000 IU/day)), intake duration (short-term (<12 months) and long-term use (≥12 months)), and timing of use (current use, former use, no use). RESULTS We enrolled n = 6912 subjects with vitamin D measurements: n = 5195 females (75.2%), age 44.0 ± 16.8 years, BMI 27.9 ± 6.5 kg/m2; never users: n = 5553 (80.3%), former users: n = 533 (7.7%), current users: n = 826 (12.0%). Current use of VDS was higher in females. VDT rose from 42.1% in 2014 to 92.7% in 2022, and VDA rose from 14.8% to 25.5% for the same time. VDA was found overall in n = 1511 (21.9%); Never users: n = 864 (15.6%), Former users: n = 123 (23.2%); and Current users: n = 370 (44.8%). The maximal VDA (67.9%) was found in subjects using high-dose VDS in the long term. CONCLUSIONS Despite the significant rise in VDT and VDS use, VDA was found in a minority of patients. Prolonged use of high-dose supplements produces modest improvements in VDA.

VIČIČ V, PANDEL MIKUŠ R. Vitamin D Supplementation During COVID-19 Lockdown and After 20 Months: Follow-Up Study on Slovenian Women Aged Between 44 and 66. Zdr Varst 2023; 62:182-189. [PMID: 37799414 PMCID: PMC10549253 DOI: 10.2478/sjph-2023-0026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 09/11/2023] [Indexed: 10/07/2023] Open
Abstract
Introduction The main objective was to assess the impact of the COVID-19 pandemic on vitamin D supplementation habits and their changes in the follow-up, 20 months after the study in Slovenian premenopausal and postmenopausal women. Methods A cross-sectional study was conducted between March and May 2021. 176 healthy women aged 44 to 65 from the Central Slovenian region were included in the final analysis. Vitamin D status was determined by measuring 25(OH)D concentration. After 20 months an online follow-up questionnaire was sent out, to which 123 participants responded with complete data. Results Between March and May 2021, 61% of the participants were supplementing vitamin D. 55% of the supplementers and 88% of the non-supplementers had insufficient levels (total 25(OH)D <75 nmol/L). After 20 months in the follow-up, it was found that 62% of participants were taking vitamin D supplements, but only 70% of those who had initially reported taking supplements were still doing so. In the follow-up 61% of participants stated that they started or increased vitamin D intake due to COVID-19. Conclusions Vitamin D supplementation increased 7-fold compared to pre-pandemic levels and remained at a high level after 20 months. However, a significant number of participants discontinued supplementation, and only one-fifth were taking vitamin D throughout the entire year. Supplementation is effective for vitamin D deficiency prevention only at the individual level, however due to low compliance it should not be the only strategy for preventing vitamin D deficiency in the population.
