Abstract
Ca and mineral requirements in term and premature infants are the subject of recent studies. We proposed to establish reference values for Ca and P regulating agents in healthy term formula fed infants. Ca, iCa, P, Mg, 1,25(OH)2 vitamin D (1,25D), 25 OH vitamin D (25D), parathyroid hormone (PTH), calcitonin (CT) and alkaline phosphatase (Alk Phos) were measured in 24 healthy term infants at 2,4,6,12,18 wks and 6, 9, 12 mo. All were exclusively formula fed (Similac 20-Fe) for the first 6 mo, when Gerber baby food was added for all. Mothers kept a 3d/wk record of all intake. In addition grps of infants receiving soy milk, human milk or a whey predominant formula were studied. Ca, Mg, iCa did not change significantly over the 1st yr of life, P decreased. PTH and CT did not change; Alk Phos 25OHD and 1,25OHD increased slightly. By preliminary analysis, whey predominant formula were not different from Similac fed infants. Soy milk infants showed significant differences compared to casein or whey formula fed infants.
This provides a basis for data comparison in mineral nutritional studies in the 1st yr of life. (*=±S.D.)
