Abstract
Objectives: To evaluate the growth pattern of Very Low
Birth Weight (VLBW) infants (birthweight <1500g) during
hospital stay and to compare the growth of Small for
gestational age (SGA) and Appropriate for gestational age
(AGA) infants.
Study design: Prospective observational study.
Setting. Level III Neonatal Intensive Care Unit (NICU) in
Northern India.
Participants: A cohort of 97 VLBW infants, admitted to
NICU at Sir Ganga Ram Hospital, from 1 January, 2007 to
31 July, 2008.
Intervention/Measurement: Weight, length and head
circumference (HC) were serially measured from birth till
discharge and respective Z scores were calculated as per
data from Fenton’s references. Growth was also assessed
by superimposing these trends on Ehrenkranz’s postnatal
growth charts.
Results: The mean Z scores for weight, length and HC at
birth were –1.17, –1.09 and –0.54, respectively. These
decreased to –2.16, –2.24 and –1.35, respectively by
discharge. Both SGA and AGA infants exhibited a
decrease of approximately 1 Z score in all parameters. On
postnatal charts, growth of infants remained at or above
respective reference lines, except in those below 1000g at
birth. Average daily weight gain after regaining birth weight
was 15.18 ± 1.7 g/kg/d, whereas the increase in HC and
length were 0.48 ± 0.2 cm/week and 0.60 ± 0.4 cm/week,
respectively. These increments when compared to the
intrauterine growth rates, indicated discrepant growth
trends.
Conclusions: VLBW infants suffered significant growth
lag during NICU stay and exhibited disproportionately slow
growth of HC and length.
