Factors associated with the Dubowitz neurological examination in preterm new-borns

Abstract

Background: This article aims to explore the factors associated with Dubowitz neurological examination scores in preterm new-borns. Methods: This is a cross-sectional study in which forty preterm new-borns were evaluated by using the Dubowitz neurological examination on their first outpatient visit following hospital discharge. A questionnaire was also deployed to explore parental variables. Results: Preterm new-borns with low scores in the Dubowitz neurological examination were born at an even lower gestational age, required longer hospitalisation, and had more indicators for orotracheal intubation. Positive correlations between the subdomains of the Dubowitz neurological examination with birthweight, mother's age, Apgar score at 5 min, maternal and paternal education, and income were also significant. Linear regression analyses explained 26% of the of the Dubowitz neurological examination global score, retaining birthweight, income, and father’s age as significant predictors. Conclusions: Early, appropriated neurological assessments of preterm infants are critical to detect risk factors that may underpin developmental delays.
