Unadjusted analysis by Student t-test for continuous values and chi-square for binary outcomes. Adjusted analysis with additional variables of age, educational level, income and smoking status at inclusion, child’s sex and gestational length at delivery (sex and gestational length not included in z-score analysis, gestational length not included in analysis of gestational age at birth)
^az-score and percentile determined according to population-specific assessment of birth weight according to sex and gestational age [40]
^bAnalysis not performed due to small numbers
