Aim: The aim of the present study is to evaluate the effect of human milk feeding during the first weeks of life in very low birth weight infants on weight gain at discharge, length of hospitalization, postmenstrual age at discharge and nutritional assessment, growth and neurodevelopment at two and five years. Material and methods: Longitudinal study of very-low-birth-weight infants (< 1,500 grams) admitted to the Neonatal Intensive Care Unit of La Paz University Hospital, from January 1^st 2009 to December 31^st 2009, followed in the follow-up clinic. Their parents agreed to perform a more exhaustive anthropometric study at five years, classified according to the type of feeding at the time of discharge (exclusive human milk, formula milk or mixed). Initial hospital duration and anthropometry at discharge were evaluated. At two years of age, anthropometric data (weight, height and head circumference) were collected and neurodevelopment was assessed according to the Bayley scale of child development. Data at five years were collected prospectively. Measurements of weight, height and head circumference, waist circumference, hip, relaxed and contracted arm, thigh and middle leg, bicipital, triceps, subscapular, suprailiac and leg skin folds were performed. For patients older than five years, the Kaufman test battery for children was used. The effect of human milk on the variables of interest was investigated using a multivariate analysis correcting for gestational age and weight at birth. Results: One hundred and fifty-two infants born in 2009 were discharged from our unit: exclusive breast milk (59), formula (55) or mixed milk (38). More detailed follow-up was carried out for 61 of them. Human milk during the first admission decreases the initial hospital stay, and is associated with a higher head circumference at two and five years, and a better score in the global and verbal cognitive area at five years. Conclusions: Our results suggest that maternal milk feeding during initial admission should be encouraged because it can improve neurodevelopment at five years of age.
