Figure 1 Adjusted odds ratios for preterm birth<37 weeks (Figure 1A), late preterm birth from 34 to 36 weeks (Figure 1B), and very preterm birth<32 weeks (Figure 1C) for infants whose parents are both foreign-born from the same country versus infants whose parents are both Canadian-born (the referent). Odds ratios are adjusted for maternal age, paternal age, parity, marital status, income quintile, infant sex and twin pregnancy. Data “suppressed” for those with<5 very preterm births.
