Pregnancy outcomes in Canadian women with disabilities: Results from linked survey and health administrative data.

We compared maternal, labour/delivery, and birth outcomes in women with vs. without disabilities using a linkage of 2003-2014 Canadian Community Health Survey and 2003-2017 Discharge Abstract Database data. Modified Poisson regression was used to compare 15 to 49-year-old women with (n=2,430) and without (n=10,375) disabilities with a singleton birth ≤5 years after their CCHS interview. Women with disabilities were at elevated risk of prenatal hospitalization (10.3% vs. 6.6%; aPR 1.33, 95% CI 1.03-1.72). They were also at elevated risk of preterm birth (8.7% vs. 6.2%), but this was attenuated after adjustment. Women with disabilities could benefit from tailored prenatal care.
