*Analysed using logistic regression and presented as adjusted odds ratios (95% CI).

**Analysed using linear regression with robust estimation and presented as adjusted mean differences (95% CI).

All regression models were adjusted for maternal age, smoking, alcohol, ethnic origin, infant sex, SCOPE centre and BMI.
