Adaptive capacities of full-term babies of breastfeeding age born in different cities of the Russian Federation

Aim. To investigate adaptive capacities of full-term babies of breastfeeding age born in different cities of the Russian Federation. Materials and methods. This was a cross-sectional (transverse) study involving 244 infants born at 37-42 weeks of gestation. Of them, 219 babies were from mothers with past extragenital diseases and a complicated obstetric and gynecological history. These infants were from St. Petersburg (group 1, n=110) and Smolensk (group 2, n=109). Twenty-five healthy children were from Tver (group 3). Children underwent serial examinations including cardiointervalography at the age of 1 (n=229), 3 (n=217), 6 (n=200), 12 (n=203) months. Statistical analysis was performed using nonparametric methods. Results. On days 2-3, 75% and 68% of babies in groups 1 and 2, respectively, needed personalized recommendations. Children in group 1 were more likely to require non-drug and drug therapy than infants in group 2. At one month, 68% and 75% of children in groups 1 and 2, at three months 64% and 74% of children in groups 1 and 2, at six months 50% and 56% of children in groups 1 and 2, and at 12 months 54% and 60% of children in groups 1 and 2 needed such interventions. The majority of children in group 1 did not require personalized correction. Conclusion. Children born in different cities of the Russian Federation had statistically significant differences in functional adaptation reserves. These differences were associated with maternal past extragenital diseases and a complicated obstetric and gynecological history regardless of the babies’ city of birth. Subsequently, they affect the health status of the children.
