ELBW adolescents show lower neurocognitive performance, grip strength and high-er fat body mass. Catch–up growth for weight in ELBW children in the first two years of life was associated with lower fat body mass. Renal length and glomerular filtra-tion rate (cystatin C) were 0.28 cm (95% CI 0.09–0.47) and 11.5 mL/min/1.73 m2 (6.4–16.6) lower in cases. The odds of having systolic (pre)hypertension in former ELBW cases was 6.43 (2.52–16.4) and 10.9 (2.46–48.4) with a low renin mechanism. Microvascular retinal arteriolar narrowing is observed in former ELBW young adolescents.Conclusions The phenotype (growth, body composi-tion, renal function, retinal microvascularisation) of former ELBWs differs significantly from controls in early adoles-cence. All these findings reflect mechanisms related to a higher risk factor for adverse health outcomes in adult-hood. ER -
