Brief Summary:
The purpose of this study is to identify calcium metabolism characteristics in Mexican American adolescents The investigators predict that calcium requirements to maximize bone health in this population will be lower than for white youth but higher than their current intakes
Detailed Description:
Previously significant racial and sex differences in calcium retention and kinetics in adolescents has been found Other minority groups have increased calcium absorption efficiency at low calcium intakes in contrast to white adolescents Since Hispanics and specifically Mexican Americans will soon comprise an increasing proportion of our population We propose to identify calcium metabolism characteristics in this group We predict that calcium requirements to maximize bone health in this population will be lower than for white youth but higher than their current intakes
Thus the specific aims of this project include
to establish calcium requirements
to establish the relationship between calcium intake and calcium absorption
to identify the major physiological parameterskidney intestine bone that contribute to calcium retention in Mexican-American adolescents
During this two-phase metabolic camp participants will consume either a higher calcium diet1100-2300mgd or a lower calcium diet 600-1200mgd during the first 3-week phase and switch to the opposite regime during the second 3-week phase with a 2-week washout period in between Subjects will collect all excreta during both phases Calcium absorption height weight and bone density will evaluated throughout the 6-week period of the study
