Extract: Bone mineralization rate in preterm infants in unknown. The effect of a new formula on bone mineralization in very low-birth-weight infants (28 to 32 weeks gestation) was studied using infant-adapted direct photon absorptiometry. The 81 calories/dl experimental formula (Similac Special Care) contained 50% of the carbohydrate as Polycose, 50% of the fat as medium-chain triglycerides, and a whey: casein protein ratio of 60:40. It also contained large amounts of calcium (140 mg/dl), phosphorus (75 mg/dl), and vitamin D (120 IU/dl). Over a 3-5 week period, bone mineralization increased in two-thirds of the infants and decreased in the remainder, but all values remained in the range expected for bone mineral content in utero. Serum calcium, phosphate, magnesium, alkaline phosphatase, 25-hydroxy-vitmain D, and parathyroid hormone concentrations remained stable, whereas calcitonin concentrations fell. (author)
