A recent study conducted on 40,000 mothers and their babies found that 1-in-5 women gain too much weight during pregnancy, which doubles the chances of their babies gaining 9-pounds or more.
The findings of the research by Dr. Hillier M.D., of Kaiser Permanente Northwest and colleagues have been published in the November issue of Obstetrics and Gynecology.
The research also found these babies are prone to obesity later in life.
"The take-home message is that all pregnant women need to watch their weight gain and it is especially important for women who have risk factors like gestational diabetes," said Dr Hiller
