  1. Data presented are n (%) for categorical variables and mean ± SD for continuous variables.
  2. BMI body mass index; overweight, BMI for sex and age ≥85th, PBF percent body fat, High adiposity PBF for sex at age 4 years ≥85th, FFM fat free mass, BFM body fat mass, LGA large-for-gestational age (birth weight >90th percentile), AGA appropriate-for-gestational age (birth weight 10–90th percentiles).
  3. aP values for comparisons between the two groups adjusted for maternal (pre-pregnancy BMI, education, alcohol in pregnancy, gestational diabetes mellitus) and infant (cesarean section, sex, gestational age, breast feeding) characteristics; other variables were excluded since they were comparable and did not affect the comparisons. P values in bold: P < 0.05.
