An estimated 10 million Americans age 50 and older have osteoporosis, and many experience associated fractures. Although several interventions have been shown to be effective in preventing osteoporosis, their impact on bone health among older adults was limited. The aim of this study was, therefore, to examine the effects of a theory-based online bone health program (Bone Power program) for a large number of older adults. The 8-week program included learning modules, discussion boards, and other resources. Participants ( N = 866; M age = 62.5 years) were recruited online and randomized into a Bone Power or control group. At the end of the intervention, the Bone Power group showed significantly greater improvement over the control group in osteoporosis knowledge, self-efficacy/outcome expectations for calcium intake and exercise, and calcium intake and exercise behaviors. This study's findings suggest that online health programs can be effective in improving older adults' knowledge, beliefs, and health behaviors.
据估计，1000万年龄在50岁及以上的美国人患有骨质疏松症，许多人还经历过相关骨折。尽管有几种干预措施已被证明对预防骨质疏松症有效，但它们对老年人骨骼健康的影响有限。因此，本研究的目的是检验一项基于理论的在线骨骼健康计划（骨骼力量计划）对大量老年人的效果。这个为期8周的计划包括学习模块、讨论板和其他资源。参与者（N = 866；平均年龄 = 62.5岁）通过网络招募，并随机分为骨骼力量组或对照组。在干预结束时，骨骼力量组在骨质疏松症知识、钙摄入和运动的自我效能/结果期望以及钙摄入和运动行为方面比对照组有显著更大的改善。本研究结果表明，在线健康计划可以有效地提高老年人的知识、信念和健康行为。
