VITAMIN D STATUS AMONG TBILISI HEALTHY PEDIATRIC POPULATION

Abstract

Objectives. Vitamin D deficiency has been identified as a common worldwide metabolic/endocrine abnormality. There is no published data about vitamin D plasma level in Georgian population. Present study was conducted to reveal vit D status among healthy children from Tbilisi pediatric population.

Material and Methods. The present study was performed to study vit D plasma level in healthy children at age 1 to 15 years. The 3 groups of children were formed – in the I group were included 63 children at age 1 to 5 years; II group formed 50 children at age 5 years +1month to 10 years and III group formed 17 children at age 10years+1 month to 15 years. One moment blood concentrations of 25(OH)D were determined in every study participant.

Results. Mean serum 25(OH) vitamin D level in the I age group was – 35.54ng/ml ± 8.66. In II age group vit D level was 27.71 ± 18.29 ng/ml. In III age group mean serum 25(OH) D level was – 28.31 ± 12.59ng/ml. Comparison of serum 25(OH) vitamin D levels between the I and III study groups revealed a statistically significant difference (p < 0.05). In 14% of healthy adolescents from group III the vit D plasma level was <20ng/ml (16±11.5ng/ml).

Conclusion. Only children <5 years revealed 25(OH)D sufficient plasma concentration. In elder children (groups II and III), were diagnosed Vit D insufficiency. 14% of adolescents revealed vit D deficiency (<20ng/ml).
