跌倒是老年人伤害死亡的重要原因，且医疗负担重，如何科学有效预防已成为全球重要公共卫生问题。前期研究发现我国跌倒预防项目成分较单一、缺乏高质量证据支持，更无转化应用。LIVE-LiFE是一项循证多成分跌倒预防项目，被证明能有效减少老年人跌倒、参与依从性高。本研究拟本土化调适此项目，探讨调试后该项目对中国社区老年人跌倒的预防效果及机制。该研究采用双组单盲随机对照试验，实验组接受为期12周的LIVE-LiFE干预（个体化的平衡与力量训练、视力筛查、药物评估、居家风险评估与居家修缮和改造），对照组接受同等剂量的健康教育。评价项目在干预结束时、6个月、12个月对两组老年人跌倒发生率、相关健康结局指标，及医疗卫生利用的干预效果；探讨其作用机制。调适后的LIVE-LiFE有望在我国形成优质证据，后期转化为健康养老服务应用于社区老年人跌倒预防，从而推动基层老年人健康管理工作，为实现健康老龄化奠定基础。

Falls are an important cause of injury and death in older adults, resulting in substantial medical burden. How to prevent falls scientifically and effectively has become a significant global public health problem. Previous studies have found that the fall prevention programs in China are mostly single component, without high-quality evidence support. There is even no relevant translation and application. The LIVE-LiFE is an evidence-based multi-component fall prevention program that has been shown to be effective in reducing falls among community-dwelling older adults, and it has high adherence. This study aims to adapt the LIVE-LiFE into the Chinese context and to examine its effect and mechanism in preventing falls among Chinese community-dwelling older adults using a single-blinded randomized controlled trial design. Older participants will be randomized to either the treatment group to receive the LIVE-LiFE (individualized strength and balance training, vision screening, medication review, home hazards assessment and home repair and modification), or the control group to receive the same dosage of health education. In this study, we will evaluate the effect of the program on the incidence of falls, related health outcome indicators, and health care utilization of the two groups at the end of the intervention, six months and twelve months, respectively. The adapted LIVE-LiFE is expected to establish high-quality evidence in China and to be later translated into health care services applied to prevent falls among community-dwelling older adults. It also helps promote the health management of the elderly at the grassroots level and lays a foundation for the realization of healthy aging.
