New research explores the link between baby birthweight, length of pregnancy and future cognitive problems
A new study has explored the link between infant birthweight, gestational age and future cognitive problems.
Published today in JAMA Network Open, scientists have shown how the relative birthweight of infants associates with cognitive performance at five years of age. The results broadly indicate that a large birthweight is good for IQ, but this is relative to gestational age (the week of pregnancy the baby is born – for a healthy nine-month pregnancy this is 40 weeks).
Previous studies had shown that a combination of how heavy a baby is at birth and how early it is born relates to later cognitive abilities, but this study investigates whether the relative birthweight (being born at a lower birthweight relative to how many weeks long a pregnancy is), might also be important for later cognitive performance.
Infants whose birthweight is very low compared with those born at the same gestational age appear more likely to experience developmental problems later at five years of age.
