Aim: We describe the postnatal weight gain, linear and head growth trends of surviving preterm infants from 2005 to 2017.Methods: Multicentre cohort study, including surviving preterm infants <32 weeks (n = 21 084), from the Spanish Neonatal Network database, without major congenital malformations who were less than 50 weeks postmenstrual age at discharge. Outcomes were weight gain (g/kg/day), linear and head growth (cm/week) and changes in weight, length and head circumference z-scores from birth to discharge. The study period was divided into Results: Weight gain, linear growth and head growth were slightly higher in 2015-2017 than in 2005-2008: 12.2 AE 2.6 to 13.1 AE 2.5 g/kg/day, 0.98 AE 0.6 to 1.03 AE 0.6 cm/ week and 0.76 AE 0.2 to 0.77 AE 0.3 cm/week, respectively. It was associated with a decreased fall in weigh, length and head circumference z-scores from birth to discharge (À1.32 AE 0.9 to À1.01 AE 0.84, À1.38 AE 1.2 to À1.18 AE 1.2 and À0.41 AE 1.2 to À0.33 AE 1.3, respectively).Conclusion: Postnatal growth restriction remained a common complication of prematurity despite some increment over the last years. Growth disproportionality seemed to be worsening as weight gain was increased more than linear growth.
