Predicting neurodevelopmental outcomes at preschool age for children with very low birth weight.
Four easy-to-get facts soon after birth forecast most of the later IQ and a big chunk of motor and daily-living skills in very low birth weight five-year-olds.
01Research in Context
What this study did
Doctors tracked very low birth weight babies from hospital discharge to age five. They recorded early medical problems, mom's education, and first-year Bayley motor and cognitive scores. At five years they tested IQ, motor, and daily-living skills again.
What they found
Four early facts explained over half of the children's IQ and about one-third of motor and self-care scores at age five. The four facts were: medical complications, mom's education level, and the baby's first motor and cognitive test scores.
How this fits with other research
Wu et al. (2016) extends these results. They show that clinic or home parent coaching can still nudge emotion skills in the same VLBW group, so prediction does not mean destiny. Mas et al. (2019) used the same Bayley-III tool and also linked an early medical detail—low calorie intake—to later lower scores, matching the medical-risk part of the model. Magiati et al. (2001) sounds like a contradiction: they warn that Bayley scores can under- or overestimate ability by up to 20 points depending on which test you pick. The studies do not truly clash; Tsu-Hsin used Bayley consistently for all kids, while I et al. compared different tests. Use the same tool each time and the rank order stays reliable.
Why it matters
You can spot the highest-risk VLBW toddlers before age two. Pull the four predictors from clinic charts: severe neonatal complications, mom finished high school or not, and the 12-month Bayley motor and cognitive scores. Flag kids with two or more risk factors for extra therapy hours or closer follow-up. Share the numbers with families so they understand why early services matter.

03Original abstract
The purpose of this study was to examine predictors of neurodevelopmental outcome in very low birth weight children without major impairment at 5 years of age, as well as to identify the contribution of early neurodevelopmental assessment to preterm children's later developmental outcomes. The participants in this study included 126 children who were prematurely born with very low birth weight. Outcomes of the childrens' later development were measured in tests that factored cognitive function, motor performance, and adaptive behavior. The results indicated that more than 50% of full-scale intelligence and 30% of both motor performance and adaptive behavior at the age of 5 can be explained by four predictors. The four predictors include preterm children's medical complications at birth, maternal education, early motor assessments, and cognitive assessments. Adding each test score obtained in early ages provides additional information to predict children's cognitive, motor, and adaptive behavior at 5 years of age. Manifold assessments conducted in multiple time periods strengthen the predictive values of later developmental outcomes. In addition, the findings of this study indicate that very low birth weight children tend to have lower adaptive behavior at 5 years old. With regard to our findings, we believe that having adaptive function is a reflection of a child's overall integrated abilities. Further study is warranted to increase understanding of this topic, as well as to be able to predict adaptive strengths and weakness and pinpoint limiting factors that may be useful for targeting behaviors in intervention.
