A previous study using single photon absorptiometry has reported low bone mineral density of the radius in infants of diabetic mothers. The aim of this study was to assess by dual x-ray absorptiometry the whole body bone mineral content (WbBMC) and the body composition of 40 infants of diabetic mothers at birth (mean gestational age ± sd, 37.5 ± 1.3 weeks; mean birth weight ± sd, 3815 ± 641 g). WbBMC was not correlated with gestational age, but was well correlated with birth weight (r = 0.73; P = 0.0001) and also with fat mass (r = 0.87; P = 0.0001) and lean mass (r = 0.42; P = 0.008). The z-scores ± sd adjusted for weight for WbBMC and fat mass were significantly increased (1.3 ± 0.9 and 2.6 ± 1.3, respectively (P < 0.0001), but were not significantly influenced either by in utero growth or by the type of the diabetes mellitus of the mother. Bone mineralization and fat mass studied by whole body dual x-ray absorptiometry are increased at birth in these infants compared with reference curves.

Background: Interactions between the genome and intrauterine environment can affect bone mineralization in newborns and even in adult life. Several studies show that intrauterine fetal bone mineralization or early postnatal bone condition influences the risk of osteoporosis in later life.Objectives: To determine whole body bone mineral content (WB BMC) and factors that influence neonatal WB BMC in Indonesian term newborns.Subjects/Methods: A cross-sectional study was conducted in Dr. Sardjito General Hospital, Yogyakarta, Indonesia. A total of 45 term, appropriate for gestational age (AGA) newborns were included in this study. BMC was assessed by dual-energy x-ray absorptiometry (DXA) in the first week of life. Weight (g), length (cm) and head circumference (cm) were measured at birth. Data on maternal characteristics were obtained from the maternal health records or reported by the mothers.Results: WB BMC measured in the present study (mean ± SD: 33.2 ± 9.3 g) was lower than WB BMC of similar populations in developed countries. Multiple linear regression showed that birth weight, birth length, and gestational age had a positive association with WB BMC (p = 0.048, 0.017, and <0.001, respectively), while maternal cigarette exposure had a negative association with WB BMC (p = 0.012). Male infants had significantly higher of WB BMC than female (p = 0.025). These determinants contribute to 55% variability of WB BMC.Conclusions: WB BMC in Indonesian term newborns is lower than populations in developed countries. Birth weight, length, gestational age, sex, and maternal cigarette exposure during pregnancy are significantly associated with WB BMC observed in Indonesian newborns.

Bone mineral content was determined by photon absorptiometry, adapted for use in neonates, in 23 small-for-gestational-age (SGA) infants of 31 to 42 weeks of gestational age, for 12 weeks. At birth, term SGA infants had lower bone mineral content than term appropiate-for-gestational-age (AGA) infants; postnatal increase in bone mineral content was slow and lagged significantly behind that of term AGA infants. Preterm SGA infants had bone mineral content that was similar to that of preterm AGA infants at birth; postnatal bone mineral content was similar to that of preterm AGA infants, but was decreased compared with the expected intrauterine bone mineral content. Serum 25-hydroxyvitamin D concentrations and parathyroid hormone levels were the same for SGA and AGA infants. Serum 25-hydroxyvitamin D concentrations decreased slightly with postnatal age and remained within normal limits. Serum parathyroid hormone concentrations decreased in both SGA and AGA infants and reached undetectable levels at 10 to 12 weeks of age.
