The timing of anemia—a common condition in late pregnancy—can make a big difference for the developing fetus, according to research at Karolinska Institutet published in JAMA Psychiatry. The researchers found a link between early anemia and increased risk of autism, ADHD and intellectual disability in the child. Anemia discovered toward the end of pregnancy did not have the same correlation. The findings underscore the importance of early screening for iron status and nutritional counselling.
