PDI = psychomotor developmental index; NCAFS = Nursing Child Assessment Feeding Scale; SD = standard deviation
Adjusted changes (and 95% confidence intervals) in Bayley II PDI at one year corrected gestational age, associated with a 1 SD increase in total NCAFS score and in the scores for each domain of the NCASF among 119 caregiver-preterm infant pairs are shown.
Linear regression models were adjusted for infant gestational age at birth and discharge, birth weight, gender and receipt of mechanical ventilation; maternal age, race, education status and smoking and alcohol use during pregnancy; and mode of infant feeding (direct breastfeeding or not) and type of caregiver (mother or not) at the post-discharge NCAFS visit. Note, when the confidence interval does not include 0, this indicates p < 0.05.
