Bolded text identifies statistically significant RRs.
a
Model 1 adjusts for maternal age, parity, neighbourhood income quintile, rural residence, and immigrant status.
b
Model 2 further adjusts for stable chronic conditions, unstable chronic conditions, mental illness, substance use disorders, and prenatal care adequacy.
