Children born to mothers who had depression during or after pregnancy are at significantly higher risk of depression themselves later in life. In fact, UPI reports a new analysis says such children are nearly twice as likely as others to develop the disorder as teens or adults. Research suggests up to 20% of women suffer from depression during pregnancy, known as perinatal depression. One in seven women -- or roughly 600,000 annually -- experience post-partum depression, which happens within one year of childbirth. Children born to mothers with perinatal depression were 78% more likely than other children to be diagnosed with the condition as adolescents or adults. Children of mothers with postpartum depression were 66% more likely to suffer from depression later in life.
