The purpose of this study was to assess the effectiveness of an educational intervention for 6th - 11th grade adolescents regarding dietary calcium and the prevention of osteoporosis. This was a secondary analysis of data from a study that used a pre-experimental pre-test-post-test; no control group design. Eighty-two boys and 102 girls completed the Healthy Bones Knowledge Questionnaire (HBKQ) as a pretest, received an educational intervention based primarily on dietary calcium intake, then completed the questionnaire again as a post-test.
As a group, the students demonstrated a significant increase in correct answers to calcium-related HBKQ items (t = 3.31, p = .001). Further analysis revealed that girls experienced a knowledge increase (t = 2.95, p = .004) while boys did not.
