【 摘 要 】

The purpose of this research was to measure and evaluate lifestyle changes affecting bone health.Osteoporosis is a public health concern.Improving bone health, thereby preventing osteoporosis and fractures, can lead to a reduction in health care costs.Calcium is a key player in bone health.With an increase in calcium-fortified foods an objective was to develop a food frequency questionnaire that assesses both natural and fortified sources of calcium.A validation study in which the Calcium-Focused Food Frequency Questionnaire (CFFFQ) was tested against a 24-hour recall in adult females (pilot study, n=15) and college-aged females (primary study, n=300).In the pilot study, no significant differences in calcium intake for total calcium or food group category was found except for calcium from “foods with dairy” (t=2.23, p=.043) and “vegetable” (t=-3.106, p=.008).In the primary study and after removal of outliers (n= 187), significant correlations (r=.155 to.74, p
