ObjectiveTo compare the neuropsychomotor development in the first year of life of
premature infants with and without bronchopulmonary dysplasia.MethodsA cross-sectional retrospective study was conducted between January 1, 2014,
and December 30, 2015, with premature infants weighing < 1,500g at birth
and diagnosed with bronchopulmonary dysplasia at the corrected ages of 6 and
9 months, assessed using the DENVER II Developmental Screening Test.
Quantitative variables were described as the means, medians and standard
deviations. Variables with normal distribution were tested using Student's
t test; otherwise, the Mann-Whitney test was used,
considering significance at p-value < 0.05. Qualitative variables were
expressed as frequencies and percentages. Logistic regression was used with
odds ratio analysis to evaluate the effects of other variables as risk
factors for changes in neuropsychomotor development.ResultsInfants with bronchopulmonary dysplasia showed greater developmental delay
compared with those without bronchopulmonary dysplasia (p-value = 0.001).
The factors associated with a higher incidence of changes in
neuropsychomotor development, in addition to bronchopulmonary dysplasia,
were antenatal steroid, gender, birth weight, 5-minute Apgar score, Score
for Neonatal Acute Physiology-Perinatal Extension, duration of oxygen
therapy, duration of mechanical ventilation and length of hospital stay.
Other variables may also have influenced the result, such as drug use by
mothers of infants with bronchopulmonary dysplasia.ConclusionBronchopulmonary dysplasia associated with other pre- and postnatal factors
may be considered a risk factor for delayed neuropsychomotor development in
the first year of life in premature infants born weighing less than
1,500g.
