Age-dependent variations in serum 1,25-dihydroxyvitamin D in childhood

Abstract

Circulating 1,25-dihydroxyvitamin D (1,25-(OH)2D) was measured in 87 children aged 3 months to 15 years, and in 11 adolescents 16-19 years of age. A positive correlation to growth velocity was observed, indicating that the biologically active vitamin D metabolite is an important physiological factor in the regulation of growth and development of the skeleton.
