Vitamin D deficiency conditions in children in the antenatal period from the perspective of prognosis and prevention

Abstract

Relevance. Irrational nutrition of a pregnant woman, unjustified drug load, inactivity, insufficient insolation, constitute a high risk of vitamin D deficiency. Vitamin D deficiency conditions correlate with the frequency of the pathological course of pregnancy and childbirth, dictating the need for timely correction from the standpoint of optimizing care for the child population. The aim of the study - evaluation of the possibility of predicting vitamin D deficiency conditions in children in the antenatal period using a complex of medical and statistical analysis methods. Materials and Methods. A prospective cohort study of 248 mother-child pairs was conducted. Pregnant women: the main group (148) - receiving vitamin D prophylactically at a dose of 1000 MG (Aquadetrim) when registering. The comparison group was those who did not receive vitamin D (100). Inclusion criteria: absence of exacerbation of chronic pathology, allergic reactions, malabsorption syndrome, obesity, diabetes, taking HA, antiepileptic drugs, hyperparathyroidism, severe infections. All women were examined at the end of the 3rd trimester and the postpartum period. Children were observed of 248 children born to pregnant women of two groups. All children were observed with the informed consent of their parents. The duration of observation is up to 3 years. An assessment of the somatic status and general clinical examinations were carried out. Risk factors were assessed using mathematical and statistical methods to compile a prognostic scenario for the development of vitamin D deficient conditions. Results and discussion. Based on the data obtained using the statistical analysis method, it was found that the pathological course of pregnancy and childbirth in women who received vitamin D during pregnancy according to the RR data, AtR were significantly less frequent. Newborns of the main group had higher mass-growth indicators, significantly less often insufficiency, vitamin D deficiency, neurological symptoms; subsequently, a lower incidence of allergic diseases, acute respiratory viral infections, changes in the bone system. Conclusions. Evaluation of the possibility of predicting vitamin D deficiency conditions in children in the antenatal period using a complex of medical and statistical analysis methods reduces the risk of: pathological course of pregnancy, childbirth, the frequency of vitamin D deficiency and deficiency in newborns, affecting mass-growth indicators at birth, neurological symptoms, allergic diseases, respiratory infections in infancy, changes in the bone system in young children. Prevention of the development of vitamin D deficiency conditions in the antenatal period makes it possible to optimize the care of the child population.
