A new study released by the University of Chicago found that three quarters of new mothers are heavier a year after giving birth than before their pregnancy. Head researcher Dr. Loraine Endres and her team sampled 774 low income women from five locations across the United States. They were interviewed and their measurements (height and weight included amongst these) taken immediately after childbirth, then 6 months after, and finally a year after.
Shockingly the findings were that a third of the women were considered overweight or obese a year after childbirth. A quarter had retained 20 extra pounds. 75% ended up heavier a year after pregnancy a 47% retained more than 10 pounds.
