Notes (1) Neighbourhood education level was defined as percentage of people aged 25–64 who had a university degree or higher at a dissemination area; (2) Neighbourhood income was defined as household income for each census metropolitan area/agglomeration; (3) Neighbourhood education level and income were categorized as quintiles. The least value is Q1 and highest value is Q5; (4) Two SES variables were in separate Poisson regression with robust error variance models while adjusting for maternal age, obesity status in pre-pregnancy, pre-existing maternal health conditions, substance use during pregnancy, race and maternal rural residence.
