Veel kinderen krijgen te weinig vitamine D*
Uit een studie onder Amerikaanse kinderen van 1-11 jaar blijkt dat bijna 70% van de kinderen een
vitamine D tekort heeft, bloedwaarden lager dan 30 ng/ml. 73% van de 6-11 jarigen en 63% van de 1-5 jarigen hebben een duidelijk tekort.

OBJECTIVE: Single-center studies have suggested that hypovitaminosis D is widespread. Our objective was to determine the serum levels of 25-hydroxyvitamin D (25[OH]D) in a nationally representative sample of US children aged 1 to 11 years.
METHODS: Data were obtained from the 20012006 National Health and Nutrition Examination Survey. Serum 25(OH)D levels were determined by radioimmunoassay and categorized as <25, <50, and <75 nmol/L. National estimates were obtained by using assigned patient visit weights and reported with 95% confidence intervals (CIs).
RESULTS: During the 20012006 time period, the mean serum 25(OH)D level for US children aged 1 to 11 years was 68 nmol/L (95% CI: 6670). Children aged 6 to 11 years had lower mean levels of 25(OH)D (66 nmol/L [95% CI: 6468]) compared with children aged 1 to 5 years (70 nmol/L [95% CI: 6873]). Overall, the prevalence of levels at <25 nmol/L was 1% (95% CI: 0.71.4), <50 nmol/L was 18% (95% CI: 1621), and <75 nmol/L was 69% (95% CI: 6573). The prevalence of serum 25(OH)D levels of <75 nmol/L was higher among children aged 6 to 11 years (73%) compared with children aged 1 to 5 years (63%); girls (71%) compared with boys (67%); and non-Hispanic black (92%) and Hispanic (80%) children compared with non-Hispanic white children (59%).
CONCLUSIONS: On the basis of a nationally representative sample of US children aged 1 to 11 years, millions of children may have suboptimal levels of 25(OH)D, especially non-Hispanic black and Hispanic children. More data in children are needed not only to understand better the health implications of specific serum levels of 25(OH)D but also to determine the appropriate vitamin D supplement requirements for children.
