  1. Age, gender, birth weight, breast feeding, mean arterial pressure and heart rate were controlled in the hypothesized model
  2. β = standardized regression coefficient; β1 = indirect effect 1; β2 = indirect effect 2; βInd = total indirect effect; βDir = direct effect; βTot = total effect; z-BMI = the z-score of body mass index. *P < 0.05; **P < 0.01; ***P < 0.001
