When comparing the control group to the macrosomic group all p values <0.001. When comparing the control group to the LGA macrosomic group all p values <0.001 except *p value=0.4 comparing % males between LGA to control group.
AGA, appropriateness for gestational age; BMI, Body Mass Index; LGA, large for gestational age; PI, Ponderal Index; WLR, weight/length ratio.
