The predictive value of early oral motor assessments for neurodevelopmental outcomes of moderately and late preterm infants

Oral motor assessment is used to identify abnormal sucking patterns which may reflect neurodevelopmental problems in preterm infants, but few studies have focused on moderately and late preterm infants. We enrolled 118 moderately and late preterm infants (mean gestational age, 35.04 weeks; mean birth weight, 2347.59 g) and analyzed the relationship between the Neonatal Oral-Motor Assessment Scale scores of these infants and the Chinese revision of Bayley Scales of Infant Development outcomes at 6 months corrected age. And the infants with abnormal sucking pattern had significantly lower Mental Development Index and Psychomotor Development Index and showed a higher rate of below average scores than control group (P = .003, P = .029, P = .022). The incoordination of suck–swallow–respiration was a risk factor for adverse neurodevelopment (RR = 3.67, 95% CI: 1.42–9.45). These indicate that abnormal sucking patterns in moderately and late preterm infants might provide some predictive value for short-term neurodevelopmental outcomes, but the clinical predictive value for developmental delay need to be determined in a longer term follow-up. This finding may offer a basis for early intervention.
