Special Considerations
The mean concentration of chromium in cow milk and infant formula was reported to be 0.83 and 4.84 μg/L, respectively (Cocho et al., 1992). There is no information on the bioavailability of chromium in infant formula.
Children and Adolescents Ages 1 through 18 Years
Method Used to Set the Adequate Intake
No data were found on which to base an Estimated Average Requirement for children and adolescents; therefore AIs have been set. In the absence of information on the chromium content of children’s diets, AIs for these age groups have been extrapolated from adults, ages 19 through 30 years, with use of the method described in Chapter 2 and rounding to the nearest 1 μg. Because urinary excretion of chromium is increased with exercise (Anderson et al., 1982, 1984, 1988b), metabolic weight (kg0.75) was used to extrapolate from the adult AI.
