Results of studies conducted around the world show a drastic deficiency vitamin D in almost all populations, and the strongest in the group of children and the elderly. The aim of this study was to evaluate the concentration of vitamin D in children aged 10-12 years.
Material and methods: The study included 42 children aged 10-12 years 24 girls and 18 boys).The obtained data were statistically analyzed using STATISTICA 10 (StatSoft Inc. Dell)
Results: Half of the subjects (n = 21) had levels of vitamin D i not greater than 14.872 ng/ml (median). The median concentrations of vitamin D was higher in the studied group of boys than girls and amounted to 16.54 vs 14.02. Most patients (n = 18; 42.8%) had levels of vitamin D between 10 and 20 ng / ml (deficiency),7 persons (16.7%) had a severe deficiency (≤10 ng/ml), a significant number of patients (n = 15; 35 7%) had a slight deficiency of vitamin D called moderate hypovitaminosis. Only two individuals (4.8%) had concentrations in the range defined as optimum.
Conclusions: The results of the present study show a deficiency of vitamin D in the study group children aged 10 - 12 years.
