Growth measures from birth to 11 years were compared for births\<26 weeks between EPICure2 (n=112) and EPICure (n=176). Growth parameter z-scores were derived from 1990 UK standards.Results Among EPICure2 children, mean z-scores for height and weight were close to the population standards (0.08 and 0.18 SD, respectively) but significantly below those of controls: difference in mean (Δ) z-scores for weight -0.42 SD (95\% CI -0.68 to {\textendash}0.17), for height -0.45 SD (-0.70 to {\textendash}0.20) and for head circumference (HC) -1.05 SD (-1.35 to {\textendash}0.75); mean body mass index (BMI) z-score in EPICure2 children was 0.18 SD, not significantly different from controls (0.43 SD, p=0.065). Compared with EPICure, EPICure2 children born \<26 weeks at 11 years had higher z-scores for weight (Δ 0.72 (0.47, 0.96)), height (Δ 0.55 (0.29, 0.81)) and BMI (Δ 0.56 (0.24, 0.87)), which were not fully explained by perinatal/demographic differences between eras. Weight catch-up was greater from term-age to 2.5/3 years in EPICure2 than in EPICure (1.25 SD vs 0.53 SD; p\<0.001). Poor HC growth was observed in EPICure2, unchanged from EPICure.Conclusions Since 1995, childhood growth in weight, height and BMI have improved for births \<26 weeks of gestation, but there was no improvement in head growth.Data are available on reasonable request.
