title: [Mineral bone content in full-term infants. Effect of anthropometric characteristics].
abstract: The clinical importance of the measurement of bone mineral content (BMC) in fullterm infants by photon absorptiometry relies on a comparatively narrow normative range that is necessary requisite to interpret the data from a single child. In the attempt to reduce the artifactual scattering of data, it was undertaken a normative study to control all variables that might affect BMC at birth. Thus, growth parameters and birth season (as an index of maternal vit. D status) were related to BMC, Bone Width (BW) and the considered growth parameters did not show any significant difference related to sex and birth season. Thus, all data were analyzed together. It appears that BMC at birth in fullterm infants averaged 92.2 +/- 14.6 mg/cm. BMC did not correlate with skeletal length, crown length and gestational age in the considered range. Conversely, significant correlation were found between BMC and BW and between BMC and body weight. We conclude that: a) birth season and sex do not affect bone mineralization in fullterm infants, b) any comparison among BMC should be established within populations homogeneous for weight and BW.
