Missing from the headline: this is only daughters of female refugees. Sons of refugees had unchanged mental illness rates, but so did daughters of male refugees. That's pretty surprising, and while it doesn't rule out a gender-roles explanation (maybe male refugees didn't describe their experiences as often?), it does gesture pointedly at epigenetic causes. Also notable: the study had a clever control (non-refugee first cousins of refugee children) which seems to account for both population genetics and gender distinctions in hospitalization.
