^aPreconceptional folic acid knowledge among respondents answering ‘other’ vs. ‘yes’ on: “A woman who wishes to become pregnant should take folic acid supplementation before she tries to become pregnant”. N = 3766; Rotterdam, the Netherlands, 2007, 2009 and 2010
^bPreconceptional intention to consult a GP or midwife among respondents answering ‘no’ vs. ‘yes’ on: “A woman who wishes to become pregnant should consult a GP or midwife before she tries to become pregnant”. N = 2771; Rotterdam, the Netherlands, 2007, 2009–2014
^cIn model I the study years were entered, in model II socio-demographics, socio-economic status and other variables were included, and in model III the observed interaction between ethnicity and educational level was included
Data are in OR, odds ratio (95 % confidence interval). OR = exp (ß), where ß is the coefficient in the logistic model
* p ≤0.05; ** p ≤0.001
NA Not Accounted
Nagelkerke for preconceptional folic acid knowledge: step I R² = 0.006, step II R² = 0.181, step III R² = 0.181 and for preconceptional intention to seek for care: step I R² = 0.042, step II R² = 0
