A recent study assessed the association between gestational weight gain and childhood cognition and it was found that weight gain during pregnancy does not influence child cognitive development.

Insufficient or excessive weight gain in pregnancy can have negative consequences for fetuses and children including infant mortality. The Institute of Medicine recently revised gestational weight gain guidelines, recommending that women gain weight within specific weight gain ranges for their Body Mass Index category. Yet little is known about the association between extremes of gestational weight gain and child cognition.

"One challenge for studies examining gestational weight gain and child outcomes is separating the effect of gestational weight gain from confounders," said Sarah A. Keim, PhD, principal investigator in the Center for Biobehavioral Health at The Research Institute at Nationwide Children's Hospital. "Confounders such as maternal intelligence, whether the family environment promotes cognitive development, family diet and exercise and some genetic factors can influence neurodevelopment postnatal and also gestational weight gain."

To address these gaps in data, Dr. Keim led a study to assess the association between gestational weight gain and the cognitive performance of children at 4 and 7 years of age. The study appears in the International Journal of Epidemiology.

Using data from the U.S. Collaborative Perinatal Project, Dr. Keim's team employed two statistical approaches. The more traditional approach adjusted for factors like the mother's weight before pregnancy, her race and the baby's sex. The other used a fixed-effects approach to control for all potential confounding factors that are shared among siblings, such as a proportion of genetic factors and parenting practices.

Findings showed that any observed detrimental influence of extremes of gestational weight gain on cognition can be explained by familial or shared genetic factors rather than gestational weight gain itself. Dr. Keim cautions that these results do not apply to preterm children and don't account for all possible confounding factors. "Strength of our approach is the potential for reduced bias in our estimates," said Dr. Keim. "However, this does not eliminate the possibility of residual confounding from factors siblings do not share. Our findings suggest that gestational weight gain is generally unassociated with child cognitive development."

sadly my little boy suffers from being overweight.. I have tried pretty much everything imaginable but feel nothing is giving any results at all. i came across this article the other day and feel I am about to give it a try. its a woman's story about her child and how her child beat his obesity and gained so much confidence [which my child greatly needs] and I am wanting a little feed back on the matter before I give it a shot. it seems great and the story has inspired me greatly and feel I need to take action to help my little boy
