Do the somatic parametres in slovak newborn on the 1^st day of life overlap the Fenton curve?

Gestational age, birth weight and birth length are basic somatic characteristics of each newborn. To compare the obtained data with the weight and growth curves according to Fenton 2013 (Fenton, 2013) and to analyze the occurrence of some risk factors (nicotinism, hypertension, gestational diabetes and diabetes mellitus) in mothers. The monitored group of newborns consisted of 2331 newborns admitted to the Neonatal Department of Intensive Medicine in 2012-2016 (n=2331). The number of premature newborns was 1061 and term newborns were 1270 (mean birth weight: boys – 2645.2 g, girls – 2443.79g; average birth length: boys – 45.82 cm, girls – 44.71 cm; spontaneous delivery: 1282 newborns, delivery of caesarean section: 1049 newborns). We found that both graphical representations overlap each other. We did not notice significant differences in the values of the monitored parameters. In our group of prenatally hypertrophic newborns above 97th percentile in 72 newborns were confirmed 8 cases of diabetes mellitus or gestational diabetes in the mother. In the analysis of the prenatal hypotrophic newborns below the 3rd percentile we found 71 hypotrophic newborns (6 cases with severe hypertension, 7 cases with multifetal pregnancy, 3 mothers during pregnancy smoked more than 20 cigarettes daily). The obtained result is based on the fact that data from the European population of newborns were also the basis for drawing up the Fenton graphs. We have confirmed the difference in birth weight and gender.
