[Serum levels of 25-hydroxycholecalciferol (25-OH-D3) in children of different age groups (author's transl)]. 1980

M Gemeiner, and D Holst-Gemeiner, and I Pilz, and W Swoboda

Serum 25-OH-D3 levels were determined in 78 children aged 6 weeks to 15 years, in March 1977 and March 1978 in Vienna. The total number of probands was divided into age groups, each comprising a range of 3 years. The average value with 1 SD. found over the whole age range was 48.3 +/- 25.75 nmol/l (i.e. 19.4 +/- 10.34 ng/ml). Somewhat higher levels were found in the age groups 3 to 6 and 6 to 9 years, with a slight decrease in the later age groups, but no significant differences were detected. The obtained values seem to represent the "normal" 25-OH-D3 serum levels of our population in the above-mentioned age range.
