We describe the postnatal weight gain, linear and head growth trends of surviving preterm infants from 2005 to 2017. Multicentre cohort study, including surviving preterm infants <32weeks (n=21084), from the Spanish Neonatal Network database, without major congenital malformations who were less than 50weeks 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 2005-8, 2009-11, 2012-14 and 2015-17. Weight gain, linear growth and head growth were slightly higher in 2015-2017 than in 2005-2008: 12.2±2.6 to 13.1±2.5g/kg/day, 0.98±0.6 to 1.03±0.6cm/week and 0.76±0.2 to 0.77±0.3cm/week, respectively. It was associated with a decreased fall in weigh, length and head circumference z-scores from birth to discharge (-1.32±0.9 to -1.01±0.84, -1.38±1.2 to -1.18±1.2 and -0.41±1.2 to -0.33±1.3, respectively). 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.
