Multicenter Study
[Vitamin D status in 6- to 10-year-old children: a French multicenter study in 326 children].
To assess the vitamin D status of children aged 6-10years in the French general population for whom no guidelines have yet been defined due to insufficient data. ⋯ At least one-third of children aged 6-10years presented deficient 25(OH)D levels. None of the children receiving a vitamin D supplement presented severe vitamin D deficiency, only a small number of children presented vitamin D deficiency (n=16 (13.4%)), and no signs of overload were observed, while one half of non-supplemented children (n=95 (50.5%)) presented at least vitamin D deficiency at the end of winter. These results support the need for vitamin D supplementation during winter in children aged 6-10years.
