ABSTRACT

INTRODUCTION Improved survival rates of neonates with very low birth weight (‹ 1500 g) have led to a higher incidence of neurodevelopmental sequelae.
OBJECTIVE Examine neurodevelopment outcomes over the first two years of life of infants who weighed ‹ 1500g at birth, in relation to birth weight, gestational age and 1-minute and 5-minute Apgar scores, in a Havana tertiary care hospital.
METHODS A case-series study was conducted to assess neurodevelopment outcomes of very low birth weight infants over their first two years of life. The study population comprised 116 surviving neonates with very low birth weight (‹ 1500g), born in the "Dr Ramón González Coro" University Maternity Hospital in Havana, Cuba, 2006–2010. A longitudinal, multidisciplinary and interdisciplinary follow up of all infants' neurodevelopment was performed, from hospital discharge to age two years, corrected for gestational age at birth. Data on each infant's perinatal variables were collected: birth weight in grams, gestational age at birth, and 1-minute and 5-minute Apgar scores. Patients were classified as having normal neurodevelopment, mild abnormalities and moderate-to-severe abnormalities. Pearson's chi-square test was used to determine possible relationships between perinatal variables studied and neurodevelopment, with exact sampling distribution and 95% confidence level.
RESULTS Normal neurodevelopment was observed in 69% of very low birth weight infants, 25.9% had mild abnormalities, and 5.2% displayed moderate-to-severe abnormalities. The results demonstrate a statistically significant relationship between gestational age and neurodevelopmental outcomes; more neurodevelopmental abnormalities were found in infants born at earlier gestational age ( ‹ 30 weeks).
CONCLUSIONS Surviving very low birth weight neonates with lower gestational age at birth face a higher risk of neurodevelopmental abnormalities.
