Abstract

We evaluated urinary calcium excretion in 21 premature infants fed either a formula containing high concentrations of calcium (Ca) and phosphorus (P) or human milk fortified with a commercially available humanmilk fortifier. Dual-tracer stable-isotope Ca absorption studies wereperformed on all infants. Urinary Ca excretion was not significantly related to Ca or P intake or true Ca absorption. The recovery of the orally administered tracer in the urine was used to evaluate the sourceof calciuria in study subjects. In almost all subjects, tissue derived (V-bu), rather than diet-derived (V-ou), Ca was the principal sourceof urinary Ca. Hypercalciuric subjects demonstrated greater V-bu and V-ou than nonhypercalciuric subjects. Our data demonstrate that moderate hypercalciuria is common in premature infants whose diets are high in mineral content and that hypercalciuria is not related to inadequate mineral intake or Ca absorption but is related, instead, to losses of both tissue and dietary Ca.
