Despite the growing prevalence of osteoporosis, many middle-age women do not engage in recommended bone health promotion behaviors. Based on the Integrated Theory of Health Behavior Change, an intervention was designed to increase the self-management behaviors of calcium and vitamin D intake by strengthening health beliefs and using self-regulation skills. In this repeated measures experimental study, a convenience sample of 148 healthy women between 40 and 60 were assigned to either the computer-based intervention group (CBIG) or usual care group (UCG). Measures of health beliefs and calcium and vitamin D intake were obtained at baseline, 8 and 14 weeks, and 6 months. An interaction effect was observed for self-efficacy and approached significance for goal congruence. The CBIG had higher level of calcium intake at 14 weeks than women in the UCG when analyzed using intention to treat. Self-efficacy predicted calcium intake.
尽管骨质疏松症的患病率不断上升，但许多中年女性并未采取推荐的促进骨骼健康的行为。基于健康行为改变综合理论，设计了一项干预措施，通过强化健康信念和运用自我调节技能来增加钙和维生素D摄入的自我管理行为。在这项重复测量实验研究中，将148名年龄在40至60岁之间的健康女性的便利样本分为基于计算机的干预组（CBIG）或常规护理组（UCG）。在基线、第8周、第14周和6个月时获取健康信念以及钙和维生素D摄入量的测量值。观察到自我效能有交互作用，目标一致性接近显著。在采用意向性分析时，CBIG在第14周时的钙摄入量水平高于UCG中的女性。自我效能可预测钙摄入量。
