Özet
Objective: To evaluate the role of some antenatal factors on bone status of newborn infants. Methods: Tibial bone speed of sound (SOS) value was measured by quantitative ultrasound within 5 days after birth in 205 neonates whose gestational ages ranged between 31 and 40 weeks. The cohort was divided into two groups according to intrauterine growth curves, as small- (SGA) and appropriate-for-gestational age (AGA). All cases were also been evaluated by antenatal ultrasonography for oligohydroamniosis. Results: The mean SOS value was found significantly higher in SGA (n = 43) than AGA infants (n = 162) (p < 0.001). The mean tibial SOS value of infants with a history of oligohydroamniosis (n = 28) was also higher than those without oligohydroamniosis (n = 177) (p < 0.001). But, in SGA infants with a history of oligohydroamniosis (n = 17), the mean tibial SOS value was similar to those SGA infants without oligohydroamniosis (n = 26) (p > 0.05). Infants whose mothers had smoked during pregnancy (n = 18) had significantly higher tibial SOS values compared to those of whose mothers had not (n = 187) (p = 0.006). In addition, mean tibial SOS values were determined higher in male infants (n = 116) compared to female infants (n = 89) (p = 0.036). There was a significant correlation between tibial SOS values and gestational age (r = 0.178, p = 0.011). Conclusions: While creating reference curves of SOS values at birth, smallness for gestational age, maternal smoking and gender as well as gestational age should be taken into account. © 2012 Informa UK, Ltd.
