dc.description.abstractWe have studied the effect of two preterm commercial infant formulas with different calcium and phosphorus contents on the mineral balance and bone mineralization of 30 preterm infants at 1 month of age. Bone mineralization was measured by dual energy X-ray densitometry. The formula supplying a higher content of calcium and phosphorus promoted higher mineral retention (P , 0.01) as well as higher bone mineral content (1.556 vs. 1.073 g, P , 0.01) and 2 bone mineral density (0.458 vs. 0.424 g / cm , P , 0.05), approaching values of the control group, which comprised a cohort of 15 preterm newborns whose gestational age was 4 weeks older than the subjects selected to be fed with the formulas. The intake of calcium correlated with retention (r 5 0.69); the phosphorus intake also correlated with phosphorus retention (r 5 0.95). Intakes of calcium and phosphorus correlated with the bone mineral content (r 5 0.65) and with bone mineral density (r 5 0.49). We conclude that formulas for preterm infants should not have a calcium content lower than 120 mg / 100 kcal and should have a calcium / phosphorus ratio of about 2 to promote adequate bone mineralization.es_ES
