[Dual photon absorptiometry in full-term newborns].
BACKGROUND
There is scanty information about bone mineral density in newborns. Normal values are needed to assess the effects of diseases and drugs used during the neonatal period.


OBJECTIVE
To assess bone mineral density in normal newborns.


METHODS
Total body bone mineral density was measured in 16 newborns with 39 +/- 1.2 weeks of gestational age, using a Norland dual photon densitometer.


RESULTS
The mean weight of newborns was 3.366 +/- 325 g. Bone mineral content was 58.3 +/- 10.8 g and bone mineral density was 0.369 +/- 9.6 g/cm2.


RESULTS
The availability of normal bone mineral content values in newborns will be useful for the assessment of conditions that affect bone mineralisation.
