Experience in implementing the International Standards for Assessing Newborn Growth INTERGROWTH-21^st

The physical development of newborns and infants is the most important parameter in assessing their health. However, the standards of anthropometric parameters, and most importantly their growth in premature babies, especially those born with low and extremely low body weight, are still controversial.Objective: to apply the methodology for measuring and assessing the main anthropometric indicators of newborns using the international standards of postnatal growth of premature babies INTERGROWTH-21st to resolve the issue of the feasibility of its adaptation and widespread introduction into neonatological and pediatric practice in the Russian Federation. 4876 children were born at Kulakov National Medical Research Center for Obstetrics, Gynecology and Perinatology (participant of the international project for the implementation of INTERGROWTH-21st standards in neonatological and pediatric practice) from 15.05.2018 to 26.11.2018. 439 (9%) of them were born premature, of which 376 children (89,3%) with gestational age confirmed by ultrasound were included in the study. There was a detailed file for each child to assess the environment and health of the mother, the course of pregnancy, childbirth, the state of health of the child from birth to discharge from the hospital. 2.1% of children classified by INTERGROWTH-21st as children with intrauterine growth retardation, according to Fenton charts, had normal intrauterine growth. When comparing the postnatal growth at discharge from hospital on the Fenton scale, more children were classified as children with impaired postnatal growth; the discrepancy between INTERGROWTH-21st and Fenton diagrams was 8%. At discharge, 52% of premature babies were exclusively breastfed, 28.8% of premature babies were at mixed feeding.Conclusion. On the one hand, the use of INTERGROWTH-21st scales helps to correct nutrition in case of delay in physical development, and, on the other hand, it reduces the risk of metabolic disorders associated with an aggressive desire to achieve rapid growth of a premature baby
