Resumen
Objetive: The study sought to determine the prevalence of postnatal growth restriction
(PNGR) and the predictors of nutritional outcome in very low birth weight (VLBW) infants.
Methods: Cross-sectional study conducted in a maternity school between July 2005-August
2006. One hundred twelve VLBW infants were assessed during hospitalization, fed
unfortified human milk and assisted by Kangaroo Mother Care. The dependent variables
included the number of days required to reach minimum weight and regain birth weight, the
percentage of weight loss, and the deterioration of nutritional status. These parameters
were converted into a factor termed “nutritional outcome” using factor analysis. Multiple
linear regression was used to identify predictors of nutritional outcome.
Results: PNGR was observed in 89.3% of the infants at hospital discharge. The predictors
of nutritional outcome were: appropriate-for-gestational-age infants, children of mothers
aged ≤ 20 years old, need for mechanical ventilation, longer stays in the neonatal intensive
care unit, and a greater number of days to achieve full enteral nutrition.
Conclusion: It is important to know the factors that negatively influence the nutritional
outcome of VLBW infants, as these can be modified through the improvement of perinatal
care and can reduce PNGR.
