A traumatic life experience in childhood increases the risk of a psychiatric disorder in the offspring.

A traumatic life experience in childhood is a fundamental risk factor of numerous psychiatric disorders. Recently, studies try to evaluate the mental health consequences on victims' offspring, but few psychiatric disorders were examined, and whether these results apply to the general population remains unknown. In this study, we use the National Epidemiologic Survey on Alcohol and Related Conditions, a large representative sample of American population, in order to estimate the impact on the offspring of a traumatic experience in parents.
