Summary: This study examines whether there is an association between complications during pregnancy and later eating disorder risk in offspring. The results showed an association between prematurity and an increased risk of ED. This is similar to the association found between prematurity and other comparison disorders, such as depression, OCD, and anxiety. A unique positive correlation was found between increasing parental age and increasing risks of ED. This varied from the U-shaped correlation found between increasing parental age and risks of comparison disorders. These results suggest that prematurity and increasing parental age may place individuals at a higher risk of developing EDs later in life.
