(Newser) – The amount of weight a mom-to-be gains during pregnancy may have a link to the weight of the child she bears, a new study finds. Gaining either too much or too little weight can both result in a greater chance that child will be obese, LiveScience reports. The research followed 4,145 women and their kids between ages 2 and 5. What they found:

  • Women with a normal body mass index before pregnancy are advised to gain 25 to 35 pounds; those who gained less were 63% more likely to have an overweight or obese kid.
  • Moms in that group who gained more than that recommended amount were 80% more likely to have an overweight or obese kid.
  • Of all women who gained less than the recommended amount of weight, some 19.5% had overweight or obese kids.
  • Of those who gained more, 20.4% had kids in that category; that's compared to 14.5% of kids whose moms gained the recommended amount of weight.
Why? "Gaining either too little or too much weight in pregnancy may permanently affect mechanisms that manage energy balance and metabolism in the offspring, such as appetite control and energy expenditure," a researcher says. The weight-gain recommendations came from the Institute of Medicine in Washington, DC, Medical Daily notes.

Or it could be the fact that most obese mothers are told to gain less weight like between 15-20 pounds. So its not that if you gain less weight it will affect the child it is more that that child is being born to a parent that already has poor eating habits and is now teaching them to their child.

My wife lost weight when she was pregnant. She was overweight prior to the pregnancy but then we had to stop drinking alcohol for the pregnancy (obviously). As such, she weighed less nine months later. He was 8 pounds, 6 ounces and has always been big - - but he's 99% in height three years later and the doctor is fine where he is weight-wise. Just too many factors to try to fit it all into some catch all recommendation.
