OBJECTIVES
To investigate whether the expanded Health Belief Model (EHBM) could predict calcium intake and physical activity in adolescent girls.
METHODS
Participants self-reported calcium intake, physical activity, and osteoporosis health beliefs. Regression analysis examined the relationship between these beliefs and behaviors.
RESULTS
Calcium self-efficacy, calcium barriers, and osteoporosis knowledge predicted calcium intake, whereas exercise self-efficacy and health motivation predicted physical activity.
CONCLUSIONS
The EHBM appears to be useful in predicting osteoporosis prevention behaviors in adolescent girls. Interventions should focus on identifying barriers to calcium consumption and physical activity and increasing beliefs in the ability overcome them.
目的
探讨扩展健康信念模型（EHBM）能否预测青春期女孩的钙摄入量和身体活动情况。
方法
参与者自行报告钙摄入量、身体活动情况以及骨质疏松症健康信念。回归分析检验了这些信念与行为之间的关系。
结果
钙自我效能感、钙摄入障碍和骨质疏松症知识可预测钙摄入量，而运动自我效能感和健康动机可预测身体活动情况。
结论
EHBM似乎有助于预测青春期女孩预防骨质疏松症的行为。干预措施应侧重于识别钙摄入和身体活动的障碍，并增强克服这些障碍的信念。
