Well-designed exercise can prevent falls in older people but previous research indicates that promoting general physical activity may increase falls. This study aimed to evaluate uptake and adherence to a physical activity promotion and fall prevention intervention among community-dwelling people aged 60 + years.
This was a process evaluation of intervention group data from an ongoing randomised controlled trial. Participants were 38 Australian community-dwelling older people assigned to intervention group who had completed 3 months of a physical activity and fall prevention intervention. Study measures included baseline daily step count assessed by Actigraph accelerometers, 12 week follow-up step count assessed by Fitbit pedometers and rating of participant engagement with the health coaching intervention.
35 participants remained in the study at week 12 and were analysed. Mean daily steps significantly increased in week 12 compared with steps at baseline (change in mean = 1101 steps, 95% CI: 285-1917, p = 0.01). Health coaching engagement was rated as high for 19 people (54%), medium for 12 (34%) and low for 4 people (12%). All participants used the Fitbit to provide feedback about daily activity.
The excellent intervention compliance and promising physical activity results demonstrate the acceptability and feasibility of this novel intervention.
精心设计的运动可以预防老年人跌倒，但先前的研究表明，促进总体身体活动可能会增加跌倒风险。本研究旨在评估60岁及以上社区居民对身体活动促进和跌倒预防干预措施的接受程度及依从性。
这是一项对正在进行的随机对照试验中干预组数据的过程评估。参与者为38名被分配到干预组的澳大利亚社区老年居民，他们完成了为期3个月的身体活动和跌倒预防干预。研究测量指标包括通过Actigraph加速度计评估的基线每日步数、通过Fitbit计步器评估的12周随访步数，以及参与者对健康指导干预的参与度评分。
12周时有35名参与者仍留在研究中并接受分析。与基线步数相比，第12周时平均每日步数显著增加（平均变化=1101步，95%CI：285-1917，p=0.01）。19人（54%）的健康指导参与度被评为高，12人（34%）为中等，4人（12%）为低。所有参与者都使用Fitbit来提供每日活动反馈。
出色的干预依从性和有前景的身体活动结果证明了这种新型干预措施的可接受性和可行性。
