Abstract
The present study explores the association between linear growth and neurobehavioral outcome in preterm (<34 weeks) when evaluated by NAPI score (Neurobehavioral Assessment of Preterm Infants) at term gestational age (GA). 80 preterm neonates were enrolled for this study and divided into two groups based on the increase in length/week at term corrected gestational age (CGA). Anthropometric parameters were calculated at various time points of study and Z scores were calculated. Neurobehavioral assessment of the enrolled infants was done by NAPI score at 37 and 40 weeks of CGA. After controlling for GA, weight Z scores, and head circumference Z scores, the median score of NAPI-motor development-vigor at 37 weeks and NAPI alertness orientation at 40 weeks were positively related to length Z scores at 37 weeks (p = 0.04) and 40 weeks (p = 0.035), respectively. Neonates with suppressed linear growth have poor short-term neurological outcomes. We recommend linear growth monitoring along with weight gain in the developed countries and diminished linear growth in the neonate as a marker to predict deviation in cognitive outcome in the future.
