Polish growth charts for preterm infants — comparison with reference Fenton charts
Abstract
Objectives: Proper infant classification, particularly a preterm infant, as small or large for gestational age, is crucial to undertake activities to improve postnatal outcomes. This study aimed to assess the usability of the Fenton preterm growth charts to evaluate the anthropometric parameters of Polish preterm neonates.
Material and methods: In this single-center, retrospective study data extracted from the medical documentation of preterm neonates born 2002–2013 were analyzed. Body weight, body length, and head circumference were evaluated and used to develop growth charts, which were compared with the reference Fenton growth charts.
Results: This study included 3,205 preterm neonates, of whom 937 were born before 30 weeks of pregnancy. Overall, 11.04%, 3.3%, and 5.2% of neonates were below the 10th percentile on the Fenton charts for birth weight, body length, and head circumference, respectively. Only 26 (6.67%) of 390 analyzed anthropological parameters differed significantly between the study and the Fenton groups. Statistically significant differences between the study and the Fenton populations were found only in body length for both sexes, and in head circumference for female neonates.
Conclusions: The growth charts developed in this study for a population of Polish preterm neonates corresponded to the Fenton charts in terms of birth weight but differed in terms of body length and head circumference. Our findings suggest the need to evaluate growth charts for Polish preterm newborns.
