Summary

Story summary

Researchers at the University of Oslo studied more than 9,300 Norwegian families to assess how genetics shape children's mental health.
They found that parents' genetic vulnerabilities influence the home environment, affecting children's anxiety and depression.
The genetic effects vary by age and indicate intergenerational transmission of risk, stronger in adolescence.
A mother's vulnerability to smoking is notable, but the study does not predict individual mental health outcomes.
