Values given are Mean (SD) or *geometnc mean (IQR) according to quartiles of birth measurements. P values were derived by using exposure and outcome variables as continuous, Standard Deviation Scores (SDS) in linear regression analyses; β represents SDS change in outcome per SDS change in exposure; p1adjusted for gestational age and sex; P2 adjusted for gestational age, sex, current BMI, pubertal stage, sample time and socio-economic status
