Washington, June 19 (ANI): Weight gain and increased head size in the first month of a baby's life is linked to a higher IQ at early school age, a new study has revealed.
Researchers from University of Adelaide Public Health analysed data from more than 13,800 children who were born full-term.
The study found that babies who put on 40 percent of their birth weight in the first four weeks had an IQ 1.5 points higher by the time they were six years of age, compared with babies who only put on 15percent of their birth weight.
According to lead author, Dr Lisa Smithers, head circumference is an indicator of brain volume, so a greater increase in head circumference in a newborn baby suggests more rapid brain growth.
The study was published in the journal Pediatrics. (ANI)
