To-be mommies! Go easy on cupcakes or your baby will be overweight
High blood sugar during pregnancy also increased the child’s risk of being obese.Updated: May 07, 2016 09:11 IST
We know it will be very hard for you to control all those food-cravings during pregnancy but there is an important reason for you to do it. A new large-scale study has shown that excess weight gain or high blood sugar levels during pregnancy increases the child’s risk of being overweight or obese, even in normal-weight babies.
Previous studies have already shown that excess weight gain and high blood sugar during pregnancy increase the likelihood of a heavy birthweight baby who is then more likely to become obese as a child. However until this new study, by the Kaiser Permanente Center for Health Research, there was little research into the effects that these risk factors could also have on normal birth weight babies, who are born at weights between 5.5 to 8.8 pounds.
The study, which looked at a diverse population of 24,141 mothers and their children, is also the largest to date on the subject.
After looking at the mothers during pregnancy and following the children from age 2 to 10, the team found that children of mothers who gained 40 pounds were 15% more likely to be overweight or obese in the first ten years of life compared to children whose mothers gained less than 40 pounds, the maximum pregnancy weight gain recommended by The Institute of Medicine.
The results also showed that high blood sugar during pregnancy also increased the child’s risk of being obese, and this risk was even higher for those children whose mothers had gestational diabetes -- the highest level of elevated blood sugar. These children were at least 30% more likely to be overweight or obese in the first ten years of life compared to children whose mothers had normal blood sugar levels.
Commenting on the results lead author Teresa Hillier explained, “When women have elevated blood sugar and gain excess weight during pregnancy, it seems to change the baby’s metabolism to ‘imprint’ the baby for childhood obesity. We’re not sure yet of the exact mechanism of this change, but it appears the baby is adapting to an overfed environment, whether from glucose or extra weight.”
The team now believe that future research should focus on how to prevent weight gain during pregnancy in an effort to combat childhood obesity.
“We can’t wait until the baby is born to determine and address the impact on childhood obesity,” said Dr. Hillier, “We need to intervene during the mom’s pregnancy to help her with nutritional and lifestyle changes that will result in healthy weight gain, healthy blood sugar and ultimately, healthy children.”
The results were published in the Maternal and Child Health Journal.
