Researchers compared the vocabulary and grammar skills of 221 children whose mothers were diagnosed with gestational diabetes to those of 2,612 children from a control group.
This study is the first to isolate the effect of gestational diabetes from other factors including family socioeconomic status, alcohol and tobacco consumption as well as maternal hypertension during pregnancy.
Between 2% and 14% of children are born to mothers who suffer from gestational diabetes. Risk factors for this complication during pregnancy include the mother’s age and her body mass index. However, the study suggests that the impact of pregnancy-related diabetes on language development is not inevitable, as children of more educated mothers appear less affected.
