Link between pregnant mothers with obesity and diabetes

breastfedA new study, published by the Cincinnati Children’s Hospital Medical Center, has revealed that there is a between pregnant mothers diagnosed with obesity and diabetes and autistic children.

One out of 45 children is affected by autism spectrum disorder (ASD) and the statistic increases on a yearly basis. The scientists noted that the increased prevalence of ASD mirrors an increase in obesity and diabetes.

The reveal that pregnant mothers with obesity or gestational diabetes were 1.5 times more likely to have a child with ASD. Four hundred and eight seven mothers had a child with ASD, 1,495 had a child with another type of developmental disorder, and 35,734 mothers of children without ASD or a developmental disorder were included for control. The average age of mothers having children with ASD was 28.6 years, and 27.4 years for both mothers of children with a developmental disorder and for controls.

Mothers with both obesity and gestational diabetes increased the two fold. The researchers analyzed and birth data from patients and mothers. Mothers who had a child diagnosed with ASD were compared to mothers of children with a non-autism developmental disorder. Mothers who had children with no developmental disorders were included in their analysis. The scientists used a novel language processing technique to analyze free medical notes and confirm autism diagnosis differentiated by a numerical code.

“Although previous studies report a link between maternal obesity and diabetes during to autism, we demonstrate that electronic medical data can verify and establish the extent of this link across large populations,” said Katherine Bowers, PhD, MPH, study senior author and a member of the Division of and Epidemiology at Cincinnati Children’s.

“Without placing any burden on study participants or the costs of developing an epidemiologic study from scratch, we can use the vast amounts of data already collected for clinical purposes to conduct broad population-based studies on this link to autism. We are very excited about the future studies we can do with this ability,” said Katherine Bowers.
