Late-term birth associated with better school-based cognitive functioning
The JAMA Network Journals

Better measures of school-based cognitive function were associated with late-term infants born at 41 weeks but those children performed worse on a measure of physical functioning compared with infants born full term at 39 or 40 weeks, according to an article published online by JAMA Pediatrics.

Evidence suggests full-term infants have better health and cognitive outcomes in childhood and into adulthood. Late-term gestation (pregnancy) is associated with increased risk of perinatal health complications. But it is unknown what long-term cognitive and physical outcomes are associated with late-term gestation.

Late-term infants outperformed full-term infants in all three cognitive dimensions (higher average test scores in elementary and middle school, a 2.8 percent higher probability of being gifted, and a 3.1 percent reduced probability of poor cognitive outcomes) compared to full-term infants. However, late-term infants also had a 2.1 percent higher rate of physical disabilities at school age and higher rates of abnormal conditions at birth, according to the results.
