Abstract

Using a stable isotopic technique in which 42Ca was administered via a bolus injection, we measured endogenous fecal calcium excretion, V_f, in five healthy children, aged 3-14 years. The V_f averaged 1.4 ± 0.4 mg/kg/day, and was lower than urinary Ca excretion (V_u) in four of the five children. These results for V_f are consistent with previously reported results for V_f in healthy adults and much lower than those reported in premature infants. These results may be useful in understanding developmental changes in Ca metabolism and in interpreting dual tracer Ca isotope studies in children.
