By 12 months of corrected age another 15 infants had demised (13.0%). The infants' trends in weight-for-age z-scores (WAZ) for corrected age was on average below the norm up to 12 months (average estimated z-score at 12 months\u2009=\u2009\u22120.44; 95% CI, \u22120.77 to \u22120.11), but had reached a normal range on average at 18 months\u2009=\u2009\u22120.24; 95% CI, \u22120.65 to 0.19) with no overall difference in WAZ scores weight between males and female' infants (<jats:italic>p<\/jats:italic>\u2009&amp;gt;\u20090.7). Similar results were seen for height at 12 months corrected age with height-for-age z-scores (HAZ) of the study subjects being within normal limits (\u22120.24; 95% CI, \u22120.63 to 0.14). The mean head circumference z-scores (HCZ) initially plotted below \u22121.5 standard deviations (S.D.), but after 6 months the z-scores were within normal limits (mean z-score at 7 months\u2009=\u2009\u22120.19; 95% CI, \u22120.45 to 0.06).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Weight gain, length and head circumferences in infants with VLBW discharged showed a catch-up growth within the first 6\u201318 months of corrected age, with head circumference recovering best.
