Being born below the 25th percentile for birthweight may put a child at risk for developmental difficulties, according to a new study by Abiodun Adanikin of Coventry University, UK, and colleagues.
Babies that are too big or too small are believed to be at risk of poor birth outcomes and problems related to childhood development, but little is known about this relationship across the entire range of birthweights for non-premature babies. To fill this gap, researchers studied the development of more than 600,000 infants born after 37 weeks of gestation in Scotland. At around two or three years of age, the children underwent evaluation for social development and for fine motor, gross motor and communication skills.
The researchers conclude that having a low birthweight is an unrecognized and potentially important contributor to the prevalence of issues related to childhood development.
Traditionally, babies below the 10th percentile were believed to be at risk for developmental concerns. But the new study found a greater number of babies within the 10th to 24th percentile range of birthweights with these issues, simply because there are a larger number of babies within that population. The researchers suggest that better birthweight surveillance, counseling for the parents and increased support during childhood may help reduce the risks associated with babies born with lower birthweights.
