Neurodevelopmental outcomes at 2 and 5 years of age in very-low-birth-weight preterm infants born between 2002 and 2009: A prospective cohort study in Taiwan

Background: Neurodevelopmental outcome in preterm infants has been of great importance in recent decades. We determined the prevalence of abnormal neurodevelopmental outcomes and associated risk factors of very-low-birth-weight (VLBW) preterm infants at 2 and 5 years of age. Methods: We conducted a...

description Background: Neurodevelopmental outcome in preterm infants has been of great importance in recent decades. We determined the prevalence of abnormal neurodevelopmental outcomes and associated risk factors of very-low-birth-weight (VLBW) preterm infants at 2 and 5 years of age. Methods: We conducted a population-based, prospective cohort study of VLBW preterm infants born between 2002 and 2009 in Taiwan. Sociodemographic, neonatal data, and neurological assessments at 2 and 5 years of age were obtained from the database of Taiwan Premature Infant Follow-up Network. Results: Of the 6549 VLBW preterm infants included in the study, 5407 (82.56%) survived to discharge; 4105 and 1427 participated in follow-up assessments at age 2 and 5 years, respectively. At age 5 years, 76.87% (1097/1427), 12.05% (172/1427), and 8.76% (125/1427) of children had normal, borderline, and abnormal neurocognitive outcomes, separately. Among the enrolled children, 1385 were followed at both 2-year and 5-year-old. Among the 233 children with abnormal neurodevelopmental outcomes at age 5 years, nearly one-fifth (18.03%, 42/233) had normal or borderline neurodevelopmental outcomes at age 2 years. Among the 154 children with borderline neurodevelopmental outcomes at age 5 years, 71.43% (110/154) had normal or borderline neurodevelopmental outcomes at age 2 years. The risk factors significantly associated with disadvantageous (worsening or remaining unimproved) neurodevelopmental outcomes were lower gestational age, cystic periventricular leukomalacia, and paternal or maternal education ≤12 years. Conclusion: Almost one-fifth of VLBW preterm children with abnormal neurodevelopmental outcomes at age 5 years had normal or borderline neurologic and developmental assessments at age 2 years. For the high risk group such as VLBW preterm children, serial follow-up assessments beyond 2 years of age may be warranted and the eligibility of early intervention service should be revised by the government so proper and targeted intervention can be implemented at earlier age.
