Clinical gestational age assessment in newborns using the new Ballard score
Abstract
Background The new Ballard score (NBS) is presently consid-ered to be the most reliable method for estimating clinical gesta-
tional age (GA) in newborn infants.
Objective The aim of this study was to compare the NBS and
Dubowitz/Finnstrom score against ultrasonography assessment of
gestational age.
Methods A cross sectional randomized study involving neonates
born in Sanglah Hospital, Bali, June to August 2004 was carried
out. Gestational age was estimated within the first 24 hour by ei-
ther Dubowitz/Finnstrom score or NBS confirmed by USG (C-
GLMP) as the gold standard.
Results One hundred and fifty-five newborns were enrolled in this
study. Subjects were randomly divided into two groups, the
Dubowitz/Finnstrom score group (76 newborns) and NBS group
(79 newborns). The mean age of mothers was 28.4 years old; mean
birth weight was 3151.3 g (SD 596.3 g). The proportion of small for
GA, appropriate for GA, and large for GA were 6%, 77% and 17%,
respectively. Pearson correlation ( r ) between C-GLMP and
Dubowitz/Finnstrom score was 0.71 (P<0.005); and with NBS was
0.79 (P<0.005) .
Conclusion The strength of correlation between either NBS or
Dubowitz/Finnstrom score and USG assessment of gestational age
are similar
