Study design Fifty-two preterm infants participated in this longitudinal cohort study (mean gestational age,
29.5 weeks; mean birth weight, 1197 g). We assessed the infants’ sucking patterns at 37-50 weeks PMA using
the Neonatal Oral-Motor Assessment Scale. At age 2 years, based on a neurologic examination and the Dutch
version of the Bayley Scales of Infant and Toddler Development, Second Edition, we categorized the children as
developing normally (n = 39) or abnormally (n = 13). ORs, including 95% CIs, were calculated to ascertain the
risk of abnormal neurodevelopmental outcomes
