• Having diabetes during pregnancy could be associated to an increased risk of neurodevelopmental disorders in the child such as autism.
• This was highlighted in a study published in The Lancet Diabetes and Endocrinology journal.
• Children exposed to maternal diabetes were at a 25 per cent increased risk of developing autism spectrum disorder, 30 per cent increased risk of Attention-Deficit Hyperactivity Disorder (ADHD), and 32 per cent increased risk of intellectual disability, compared to those not exposed, according to the findings of the study.
• Maternal diabetes was also found to increase risk of communication, learning and motor disorders among exposed children.
• However, the researchers called for a cautious interpretation of the study’s results as they said there is currently little evidence of a causal link.
• Cases of maternal diabetes — Type 1 or Type 2, or developing gestational diabetes while pregnant — are on the rise around the world.
• Factors such as obesity, sedentary lifestyle and having an advanced age at motherhood (35 and above) are considered to increase risk of maternal diabetes.
• Previous studies have suggested that maternal diabetes is linked to an altered development of the foetus’ brain, and may also be linked to long-term neurodevelopmental disorders in children such as autism and ADHD.
• However, evidence in this regard has been unclear, the researchers said.
• For the study, they analysed data of over 56 million mother-child pairs from more than 200 previously published studies, which looked at the effects of maternal diabetes on children's neurodevelopment.
• Overall, children of mothers with diabetes in pregnancy had a 28 per cent increased risk of having a neurodevelopmental disorder, compared to children of mothers without diabetes, the team found.
• They said the findings provide important insights into the potential risks faced by children of mothers with diabetes.
• The team also called for further research to look deeper into the link between maternal pregnancy and neurodevelopmental disorders in children, which could help establish the reason for this association.
