Mothers who are depressed during their pregnancy may have children who are more aggressive than others and may also have been more aggressive as teenagers themselves. Researchers from Cardiff University, King's College London and the University of Bristol studied 120 children and interviewed their mothers while they were pregnant, after they gave birth and again when their children were 4, 11 and 16. The mothers who were depressed when they were pregnant were four times as likely to have children who were violent at 16. The mothers' depression was predicted by their own aggressive and disruptive behaviour as teenagers.
