Abstract
An Hologic QDR 1000 W system equiped with a special pediatric scanning program was used to evaluate total bone mineral content (BMCt), lean body mass and fat content. 65 infants were studied, gestational age ranged from 36 to 40 weeks : 28 were appropriate for gestational age (AGA), 24 were small for gestational age (SGA) and 13 were infants of diabetic mothers (IDM). Mean birth weight (BW) ± SD was 3116 ± 557, 2015 ± 184 and 3601 ± 535 grams; mean length ± SD was 49.2 ± 2.5. 44.8 ± 1.9 and 49.8 ± 2.9 cm respectively. The scan was performed during the first day of life. BMCt (grams of hydroxyapalite), lean body mass (grams), fat content (grams), % BMCt, % fat and % lean mass were (results were expressed as mean ± SD) :
In this gestational age range (36-40 weeks), 1) BMCt in AGA group differed from both SGA and IDM categories; BMCt was belter correlated wiih birthweight than wiih gestational age. 2) Body composition in % of B W did not differ significantly between SGA and AGA infants. 3) In IDM infants, fat content increased and thus explained the heavy birthweight.
