The trajectories of LAZ,WLZ, HCZ and BAZ in different birth weight groups during the first 12 months of corrected age. (a) The Z-scores for length for age (LAZ) were significant higher for the normal-birth-weight (NBW) infants than for the low-birth-weight (LBW) and very-low-birth-weight(VLBW) infants, p < 0.01. (b) The Z-scores for weight for length (WLZ) were significant higher for the NBW infants than for the LBW and VLBW infants, p < 0.01. (c) The Z-scores for head-circumference for age (HCZ) were significant higher for NBW infants than for the LBW and VLBW infants, p < 0.01. (d) the Z-scores for body mass index for age (BAZ) were significant higher for NBW infants than for the LBW and VLBW infants, p < 0.01
