Evaluation of the factors affecting newborn weight

Abstract

Purpose: There is a trend that causes an increase in newborn weights and macrosomy rates in many countries around the world. The aim of our study is to compare the mean newborn weights in 2012 and 2016, to investigate whether there is a tendency to increase in the mean newborn weight and macrosomia rates, and to evaluate the effects of neonatal gender, mode of birth, maternal age and the season of birth on newborn weight. Materials and Methods: The data of a total of 1573 newborns 2012 (n:687) and 2016 (n=886) between 37-40 weeks of gestation were evaluated retrospectively. The data of the newborns' birth weight, gender, gestationel age, maternal age, mode of birth and season of birth were evaluated statistically. Results: It was found that there was an increase in the rate of macrosomia (birth weight ≥4000 g) from 4.9% in 2012 to 8.1% in 2016. There is a weak positive correlation between maternal age and newborn weight for both years. There was a significant increase in terms of birth weight between babies delivered by cesarean section and babies delivered by normal route 2016. It was observed that the season of birth had no effect on birth weight. Conclusion: There was an increase macrosomia rates in 2016. It was observed that maternal age and neonatal gender affected the weight of the newborn, but the seasons have no effect on neonatal weight. Maternal age, sex of newborn and gestational age were considered as independent risk factors for macrosomia.
