"Researcher, Charles Zeanah of Tulane University in New Orleans, US, analysing data from the same project, found that psychiatric disorders were 3.5 times more common among institutionalised children than among children in normal family care. He also found that foster care could help the psychiatric condition of orphaned, institutionalised children.
His group determined that children in foster homes had a reduced risk of emotional disorders, including anxiety and depression. But they found no difference in the frequency of behavioural disorders such as hyperactivity and aggression between children in foster care or institutional care. "
