1 Full-term Babies Getting Smaller in US

Babies born in the US are getting smaller, according to a new study that showed a decline in American birth weights over the past 15 years. While the decline is estimated by scientists to be an average of 1.82 ounces - not enough to be harmful to the average baby’s health - it shows a reversal of a trend that babies were getting larger since the 1950s. Weights were even lower in infants born to a subset of mothers who are considered by researchers to be low risk: white, well-educated, non-smokers who received pre-natal care. Their full-term babies weighed an average of 2.78 ounces less at birth. Researchers don’t know the reasons for the decrease but also found that the average gestation length among full-term babies dropped by more than two days.
