Case-control study on long-term kidney outcomes in very low birth weight infants: impact of growth restriction and maternal preeclampsia.

Objective: To identify factors, particularly neonatal acute kidney injury, associated with an increased risk of developing chronic kidney disease (CKD) within the first 10 years of life in children with a history of prematurity and very low birth weight (VLBW).

Methods: This nested case-control study was conducted on VLBW infants (> 500 g and < 1.500 g) born between 2012 and 2022.
