Abbreviations: BMI, body mass index; BW, birthweight; g, grams; IUGR, intrauterine growth restricted; kg, kilograms; r, correlation coefficient; s.d., standard deviation; Δ, change. aThis table summarizes results from articles that reported the correlation between prenatal growth and postnatal growth. Symbols indicate the following correlations between prenatal growth and postnatal growth were measured: positive (+), negative (−), relationship not reported (NR). Blank cells indicate the correlation was not assessed. br=−0.48, P<0.001. cSignificantly higher proportion of LBW children experienced rapid weight gain than children of appropriate BW (LBW stunted: 51.9%, LBW wasted: 75.0%, ABW: 28.0%, P<0.001). dResults not shown. er= −0.53. fLower BW SDS inversely correlated with change in weight SDS: 0–3 wks r= −0.36*; 3–6 wks: r= −0.19**; 6–12 wks: r= −0.12; 3–6 mos: r= −0.16**; 6–12 mos: r=−0.07; *P<0.001, **P<0.05. g0–6 wks: r= −0.35; 0–6 mos: r= −0.56, P<0.001. hChildren with higher 6 mos WFL z-score more likely to have higher birth WFL z-score, P=0.06. iLowest BW tertile had highest percentage of fast growers 0–3 months (53.3% vs 14.5% for highest BW tertile). jSGA children had greater change in weight SDS from birth to 3 months than AGA (1.12 (0.96, 1.29), P<0.001); LGA children experienced a decrease in weight SDS from birth to 3 months compared with AGA children (−1.25 (−1.41, −1.10), P<0.001).
