Analysis of low birth weight in different maternal-age categories

Abstract

Low birth weight is an important cause of morbidity and mortality in the neonatal and pediatric population. In addition to its relationship with adult non transmissible chronic diseases, due to its in uence on fetal metabolic programming. Considering the perinatal characteristics that in uence the weight of the newborn, the mother's age is a determining factor. The objective was to analyze the risk factors associated with low birth weight, in the different maternal age categories as a predictive factor. A 2009-2018 cross-sectional study was carried out, collecting data from 7069 neonates of the Hospital Gíneco-Obstétrico "Isidro Ayora", with birth weight between 500-2499gr. Multivariate predictive statistical models were applied according to the maternal age categories. It was found that the children of teenage mothers have the lowest affectation of birth weight, although they are a high-risk group, however, their biology and physiology are not affected by age and / or concurrent pathologies as occurs in the over 35 years old mothers. There are few national studies to compare these results, however, the validity of the finding is based on the number of cases studied and the period of time analyzed.
