What happens when abortion access becomes restricted even without a law officially passing?

With Francesco Billari and @aksoyundan.bsky.social, we investigated how incidence of abortion, miscarriage and stillbirth changed under the anti-abortion campaign in Turkey.

Immigrants typically arrive in good health but experience fast health declines. Is the same true for Asylum Seekers though?

Short answer: yes for (self-reported) physical health, but the opposite is true for mental health!
