Abstract
Extrauterine growth restriction (EUGR) occurs when a preterm newborn with adequate weight for gestational age has a weight below the 10th percentile at hospital discharge. The present study aims to establish the incidence of extrauterine growth restriction and identify associated factors. Methodology Retrospective cohort study. Preterm newborns weighing less than or equal to 1500 grams were included. Relevant qualitative and quantitative variables were collected. Statistical analysis was performed with STATA 14. Results A sample of 80 patients was obtained, 48% under 30 weeks of age and 78% weighing between 1,000 and 1,500 grams. The incidence of EUCR was 50%. Prolonged stay in the intensive care unit, being born to mothers with preeclampsia, and lower gestational age at birth affected weight gain. Conclusions Newborns born to mothers with preeclampsia have a higher risk of RCEU. This may be the result of a slowdown in antenatal growth. If they had spent more time in utero, at birth, they would have been classified as having intrauterine growth restriction. The groups with and without RCEU achieved a weight gain greater than 15 g/kg/day, which is a reflection of adequate nutritional practices.
