In a study of nearly 15,000 pregnant women, researchers found that if too much weight was gained during pregnancy, you put your child at risk.

"Are the children born to women who where obese or gained too much weight during pregnancy having problems and it did show there is an increase cardiovascular risk, which are markers for bad outcomes in children," said Dr. Ken Baker.

Families were followed for nine years. The moms who gained up to an extra 14 pounds during the first trimester had children who tested positive for cardiac risk factors.

"The markers they found in this study published in the Journal Circulation on-line was higher body mass index, they found that children had higher systolic blood pressures, higher adiposity, which is higher fat cells. They also found the lower levels of the good cholesterol, high levels of the inflammatory markers that can be a risk for cardiac disease," Baker said.

Weight gain for pregnancy is now based on body mass index. According to Dr. Baker, women underweight before pregnancy are recommended to gain up to forty pounds. Women of 'normal weight' are recommended to gain between 25 and 35 pounds. Women mildly over weight can gain 15 to 25 and those considered obese no more than 15 pounds.

According to Dr. Baker, if you are pregnant and considered overweight or obese, it's not the time to start a vigorous exercise program or restrict your diet.

"Treadmill, spinning, anything that is in moderation. We don't like you to exercise to exhaustion in pregnancy, but we do recommend to exercise to get your pulse up. Moderate exercise, 20 to 30 minutes a day, five days a week is very good for pregnancy and labor and delivery," Baker said.
