N=687 using multiply imputed data.
Values are ORs (95% CIs) comparing Māori and Pacific children and other ethnicity children to European children. Logistic regression was used for maternal educational level, with ‘more than University degree’ as the reference category. Multinomial logistic regression was used for maternal age and NZ deprivation index, with 25 to <35 years and lowest deprivation quintile used as the reference categories.
