Obesity during pregnancy could risk child’s brain development

Children’s brain development is at greater risk if their mother was obese before becoming pregnant, a study shows.
Researchers at Virginia Commonwealth University in Richmond in the US found the risk from being obese was 51% compared to 17% for those who were overweight.
They selected mothers and children involved in 41 studies from a pool of 1,483 to make an observational analysis.
Writing in the journal Obesity Reviews, they said they found that compared with children of mothers of normal weight, those from pre-pregnancy obese mothers had a 62% increased risk of attention deficit hyperactivity disorder, a 36% increased risk of autism spectrum disorder, a 58% higher risk of developmental delay and a 42% greater risk of emotional/behavioural problems.
‘Like avoiding smoking during pregnancy, this review suggests that maintaining a healthy weight during pregnancy may also be important to a child’s brain development,’ said senior author Bernard Fuemmeler.
