“…Peak bone mass may be reduced at adulthood but is mainly the result of a persistent growth retardation. 49 Thus Fewtrell et al 50 found that, at 8 to 12 years of age, former preterm infants were shorter, lighter and had lower BMC than control subjects. However, BMC was appropriate for the body size achieved and was not affected by early diet or human milk feeding.…”

“…At present, among live births in high-income countries, VLBW infants constitute approximately 0.9% to 1.5% [8],[9]. In childhood they have subnormal bone mass as compared with their term-born peers [4],[10],[11]. Whether recovery takes place before attainment of peak bone mass is unknown.…”

“…Unfortunately, bone mineralization is one of the major challenges of neonatal management in low (LBW) and very low birth weight (VLBW) infants, and osteopenia is recognized with increasing frequency (2 -4). Despite the likelihood of a spontaneous resolution of the osteopenia at the appendicular (5,6) as well as at the axial skeleton (7,8), several studies in former preterm infants have demonstrated persisting lower bone mineral content (BMC) (9,10), particularly at the hip (11).…”

Objective: To evaluate the potential role of quantitative ultrasound (QUS) investigation in assessing the osteopenia of prematurity. Design: QUS parameters measured at the time of discharge were related to the anthropometric characteristics and age (postnatal and gestational) of 51 (34 female and 17 male) preterm infants fed fortified human milk. Methods: QUS evaluation was performed at the humerus (h) by measuring two parameters: ultrasound velocity (hSOS, in m/s) and bone transmission time (hBTT, in ms). A group of 43 term infants (29 female and 14 male) was also evaluated. Results: In preterm infants, significant correlations were found for hSOS and hBTT vs gestational age (r ¼ 0.504, 0.477, P , 0.0001), length (r ¼ 0.641, 0.594, P , 0.0001) and weight (r ¼ 0.580, 0.562, P , 0.0001) at birth, and length (r ¼ 0.341, 0.332, P , 0.05) and weight (r ¼ 0.331, r ¼ 0.362, P , 0.05) at QUS measurement. In preterm infants, both QUS parameters were negatively correlated with age (r ¼ 2 0.536, P , 0.0001, r ¼ 2 0.443, P , 0.001) and were significantly lower than in the term infants (hSOS: 1664^42 m/s vs 1734^28 m/s, P , 0.0001; hBTT: 0.58^0.24 ms vs 1.06^0.15 ms, P , 0.0001) even when adjusted for body length (P , 0.05). In preterm infants, hSOS was also negatively correlated with postconceptional age (r ¼ 2 0.322, P , 0.05).Conclusions: This study suggests that bone mineral accrual is mainly determined by the development in utero, and that prematurity induces a halt in the bone development process in the early postnatal period. QUS parameters are correlated with the severity of prematurity and might therefore have clinical applications when bone maturation in early life needs to be determined.
