Falls, the leading cause of death and disability among older adults, occur in daily life when the demands of daily activities surpass the ability to maintain balance. An estimated 30% of older adults misestimate their physical function, placing them at greater risk of falling. This study examined how experiences of physical function are linked to awareness of fall risk in daily life.
For 30 consecutive days following a fall-risk assessment, 41 older adults (observations = 1,135; 56% women; age: 65-91) self-assessed objective and subjective fall risk using a custom smartphone application. Alignment of objective and subjective fall risk was indexed as awareness of fall risk. Postural sway was measured by the application. Physical and mobility symptoms and fear of falling were reported daily.
At baseline, 49% of participants misestimated their fall risk. Awareness of fall risk varied from day to day and fall risk was misestimated on 40% of days. Multilevel multinomial models showed individual differences in the level of daily symptoms to increase the tendency to misestimate fall risk. Daily symptoms and fear of falling increased awareness of high fall risk, but daily symptoms threatened awareness of low fall risk.
Findings suggest that misestimation of fall risk is common in older adulthood and informed by appraisals of physical function. Fall prevention strategies could support older adults in understanding their everyday physical function and provide tools to adjust the demands of activities in daily life.
跌倒,是老年人死亡和残疾的主要原因,发生在日常生活中,当日常活动的需求超过维持平衡的能力时就会发生。估计有30%的老年人错误估计自己的身体功能,这使他们面临更大的跌倒风险。本研究探讨了身体功能体验如何与日常生活中的跌倒风险意识相关联。
在进行跌倒风险评估后的连续30天里,41名老年人(观察次数 = 1135;女性占56%;年龄:65 - 91岁)使用定制的智能手机应用程序对客观和主观跌倒风险进行自我评估。客观和主观跌倒风险的一致性被作为跌倒风险意识的指标。姿势摆动由该应用程序测量。每天报告身体和活动症状以及跌倒恐惧情况。
在基线时,49%的参与者错误估计了他们的跌倒风险。跌倒风险意识每天都有所不同,40%的日子里跌倒风险被错误估计。多层次多项模型显示,日常症状水平的个体差异会增加错误估计跌倒风险的倾向。日常症状和跌倒恐惧增加了对高跌倒风险的意识,但日常症状会威胁到对低跌倒风险的意识。
研究结果表明,在老年人中,错误估计跌倒风险很常见,且受身体功能评估的影响。预防跌倒策略可以帮助老年人了解他们日常的身体功能,并提供工具来调整日常生活活动的需求。
