Abstract

Background: Children in northern latitudes are at high risk of Vitamin D deficiency during winter because of negligible dermal Vitamin D3 production. However, to our knowledge, the dietary requirement for maintaining the nutritional adequacy of Vitamin D in young children has not been investigated. Objective: We aimed to establish the distribution of Vitamin D intakes required to maintain winter serum 25-hydroxyVitamin D [25(OH)D] concentrations above the proposed cutoffs (25, 30, 40, and 50 nmol/L) in white Danish children aged 4-8 y living at 558N. Design: In a double-blind, randomized, controlled trial 119 children (mean age: 6.7 y) were assigned to 0 (placebo), 10, or 20 mg Vitamin D3/d supplementation for 20 wk.We measured anthropometry, dietary Vitamin D, and serum 25(OH)D with liquid chromatography-tandem mass spectrometry at baseline and endpoint. Results: Themean6 SD baseline serum25(OH)D was 56.76 12.3 nmol/L (range: 28.7-101.4 nmol/L). Serum 25(OH)D increased by a mean 6 SE of 4.9 6 1.3 and 17.7 6 1.8 nmol/L in the groups receiving 10 and 20 mg Vitamin D3/d, respectively, and decreased by 24.1 6 1.2 nmol/L in the placebo group (P , 0.001). A nonlinear model of serum 25(OH)D as a function of total Vitamin D intake (diet and supplements) was fit to the data. The estimated Vitamin D intakes required to maintain winter serum 25(OH)D .30 (avoiding deficiency) and .50 nmol/L (ensuring adequacy) in 97.5% of participants were 8.3 and 19.5 mg/d, respectively, and 4.4 mg/d was required to maintain serum 25(OH)D .40 nmol/L in 50% of participants. Conclusions: Vitamin D intakes between 8 and 20 mg/d are required by white 4-to 8-y-olds during winter in northern latitudes to maintain serum 25(OH)D .30-50 nmol/L depending on chosen serum 25(OH)D threshold.
