Stressed mothers ‘transmit stress patterns to offspring’



New research suggests that infants born to mothers who have been through stressful life events may experience changes at birth that impact their emotional behavior well into adulthood. This is according to a study published in the journal Biological Psychiatry.

Researchers from the University of Haifa in Israel say that previous research conducted in both humans and animals has shown that females who are exposed to stress even before they conceive can have an impact on offspring.

Late last year, Medical News Today reported on a study suggesting that children born to stressed mothers have a higher chance of being bullied.

A study suggests that infants born to mothers who have been through stressful life events show increased CRF1 expression at birth – a gene linked to anxiety and stress.

But the researchers wanted to determine the mechanisms as to why a parent’s stress appears to have such an impact on subsequent generations.

They focused their attention on a gene called CRF1 (corticotropin releasing factor type 1).
