Обеспеченность витамином d детей первого года жизни и коррекция его дефицита

Aim. Assesment of the status of vitamin D supply of first year life children, depending of the impact of insolation, seasonality, period of birth, dotation of vitamin D drug in the first months of life, type of feeding, and preventive reception of vitamin by mother during pregnancy and breastfeeding. Material and methods. Patients took part in research were 114 children aged 0 to 12 months, 62 from them were left without parental care (group 1), 52 from them were home children (group 2). All children underwent the determination of 25-hydroxycholecalciferol (25(OH)D) in serum. Levels of 30-80 ng/ml were recognized as normal range of concentrations of 25(OH)D, levels of 20-30 ng/ml recognized as borderline insufficiency, levels of 10-20 ng/ml as deficiency, levels less than 10 ng/ml as severe deficiency. The study of clinical and anamnestic data of mother-child pairs using mother questioning and children`s development patient charts were performed. Results and discussion. The results of the study indicated the low vitamin D supply even in first year life children, who originally were not in high risk group due to preventive administration of vitamin D in autumn-winter period. Moreover, the minimal supply were noticed among breastfed children, among mothers who did not receive dotation of vitamin D and adequate insolation in the third trimester of pregnancy. Conclusion. Children of first year of life, breastfed, born in the autumn-winter period and without adequate insolation were at risk group for vitamin D hypovitaminosis and they should be provided with a higher prophylactic dose of vitamin D during all the year.
