Models were adjusted for child’s ethnicity, birth order and maternal and paternal age, education and employment.

^aOne parent refers to either the mother or the father having the specific risk factor.

^bModels exploring systolic and diastolic blood pressure also included adjustments for maternal and paternal BMI and random blood glucose.

^cModels exploring random blood glucose also included adjustments for maternal and paternal BMI and systolic blood pressure.
