DESCRIPTION (provided by applicant): Bone health is a significant public health issue in the United States. An estimated 10 million Americans age 50 and older are living with osteoporosis, and approximately 50% of women and 25% of men over age 50 will experience an osteoporosis-related fracture in their remaining lifetime. Recent research advancements have produced effective measures to improve and maintain bone health, including exercise, diet, screening tests, pharmacotherapies, and fall prevention strategies. These findings, however, have not been fully incorporated into the daily lives of adults, and many are unaware of the magnitude of bone-health problems. Only 11-44% of adults at high risk for osteoporosis take calcium and vitamin D supplements, and one third of women over age 55 have not discussed bone health issues with their care providers. Greater efforts must be made to effectively disseminate evidence-based research findings to improve bone health behaviors of the public. The Internet, with its increasing popularity, can be an effective tool in this endeavor. Despite a great deal of available online health resources, there has been a lack of research investigating effective methods to package and deliver these resources to yield positive public health outcomes. Our prior R21 grant project showed some preliminary effectiveness of using a social cognitive theory (SCT)-based online health promotion intervention. Expanding upon our prior findings and using an innovative approach combining two models of the SCT and the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance), in this proposal, we propose a large scale online study (N = 768) that will compare the long-term impact of two SCT-based online bone health interventions in adults age 50 and older targeting two large online communities (SeniorNet, MyHealtheVet). The two interventions are (1) an 8-week SCT-based Online Bone Health (TO-BoneHealth) program and (2) a 12-month TO-BoneHealth Plus program, including the TO-BoneHealth program followed by biweekly theory- based eNewsletters with follow-up of each individual's bone health behaviors ("booster" intervention) for 10 months. The interventions' impact will be assessed on the following dimensions of the modified RE-AIM framework: (a) Effectiveness (knowledge, selected bone health behaviors, fall incidence, initiation of a discussion about bone health with a primary care provider, eHealth literacy); (b) Reach (number of participants the program reached); (c) Implementation (program usage); and (d) Maintenance (participants' bone health behavior maintenance). The Effectiveness dimension will be assessed using a randomized controlled trial employing a 3-group design (2 intervention and 1 control groups) with repeated measures (baseline, 8 weeks, 6, 12, and 18 months). The primary analytic approach for the Effectiveness dimension will involve mixed linear models analyses. Other impact dimensions will be assessed using descriptive statistics. With the rapid growth of online communities, findings from this study will significantly contribute to current eHealth practice and research and serve as a dissemination model for other health promotion projects targeting online communities. PUBLIC HEALTH RELEVANCE: Bone health is a significant public health issue in the United States, with approximately 10 million Americans age 50 and older living with osteoporosis. Several effective measures have been found to improve and maintain bone health. Many individuals, however, are unaware of the significance of bone health problems and do not follow recommended guidelines for bone health behaviors. Maximizing the popularity of the Internet, this innovative study will examine the impact of two online motivational health promotion interventions on improving mature adults' bone health behaviors. With the rapid growth of active online communities, findings from the proposed study will significantly contribute to public health by advancing current face-to-face health promotion efforts to online settings serving as a model approach.

描述（由申请人提供）：骨骼健康是美国的一个重要公共卫生问题。估计有1000万50岁及以上的美国人患有骨质疏松症，大约50%的女性和25%的50岁以上的男性将在其剩余的生命中经历骨质疏松症相关的骨折。最近的研究进展已经产生了改善和保持骨骼健康的有效措施，包括运动，饮食，筛查测试，药物治疗和预防跌倒策略。然而，这些发现尚未完全融入成年人的日常生活，许多人没有意识到骨骼健康问题的严重性。只有11-44%的骨质疏松症高危成年人服用钙和维生素D补充剂，三分之一的55岁以上妇女没有与其护理人员讨论骨骼健康问题。应加大力度，有效传播循证研究成果，改善公众的骨健康行为。随着互联网的日益普及，它可以成为这一奋进的有效工具。尽管有大量的在线健康资源，但一直缺乏研究调查包装和提供这些资源以产生积极的公共卫生结果的有效方法。我们之前的R21资助项目显示了使用基于社会认知理论（SCT）的在线健康促进干预的初步效果。扩展我们先前的研究结果，并使用结合SCT和RE-AIM框架两种模型的创新方法（覆盖范围、有效性、采用、实施、维护），在本提案中，我们提出了一项大规模在线研究（N = 768），该研究将比较两种基于SCT的在线骨健康干预措施对50岁及以上成人的长期影响，目标是两个大型在线社区（SeniorNet，MyHealthVet）.这两种干预措施是（1）为期8周的基于SCT的在线骨健康（TO-BoneHealth）计划和（2）为期12个月的TO-BoneHealth Plus计划，包括TO-BoneHealth计划，随后是每两周一次的基于理论的电子通讯，并对每个人的骨健康行为进行随访（“助推器”干预），持续10个月。将根据经修订的RE-AIM框架的以下方面评估干预措施的影响：（知识、选定的骨骼健康行为、跌倒发生率、与初级保健提供者讨论骨骼健康、电子健康素养）;（B）覆盖范围（c）实施（程序使用）;和（d）维持（参与者的骨健康行为维持）。有效性维度将使用随机对照试验进行评估，该试验采用3组设计（2个干预组和1个对照组），重复测量（基线、8周、6、12和18个月）。有效性维度的主要分析方法将涉及混合线性模型分析。其他影响层面将使用描述性统计进行评估。随着在线社区的快速增长，这项研究的结果将大大有助于当前的电子健康实践和研究，并作为其他健康促进项目的传播模式，针对在线社区。公共卫生相关性：在美国，骨骼健康是一个重要的公共卫生问题，大约有1000万50岁及以上的美国人患有骨质疏松症。已经发现了几种有效的措施来改善和保持骨骼健康。然而，许多人不知道骨骼健康问题的重要性，也不遵循推荐的骨骼健康行为指南。最大限度地提高互联网的普及，这项创新的研究将检查两个在线动机健康促进干预措施对改善成年人的骨骼健康行为的影响。随着活跃的在线社区的快速增长，拟议研究的结果将大大有助于公共卫生，将目前面对面的健康促进工作推进到在线环境中，作为一种示范方法。
