accurate classification of older people into fallers and non-fallers is crucial for falls research, but largely dependent on the accuracy of fall reporting by the participants.
to investigate the influence of memory in relation to fall reporting.
five hundred community-dwelling adults aged 70-90 years.
memory and executive functioning were assessed using the Rey Auditory Verbal Learning and Trail Making test, respectively. Fall risk was estimated using the physiological profile assessment (PPA). Falls were recorded prospectively for 12 months using monthly falls diaries and follow-up phone calls as required.
Spearman correlations showed that falls were significantly correlated to worse executive functioning, worse PPA scores and better memory. People with better memory had an increased risk of being classified as single fallers and multiple fallers, but not when reported injuries were included as part of the definition.
good memory appears to influence the recording of falls in community-dwelling older people and likely reflects a reporting bias. In research studies, there may be value in using a combination of injurious falls and multiple falls when classifying people into faller and non-faller groups.
准确地将老年人分为跌倒者和非跌倒者对于跌倒研究至关重要,但这在很大程度上取决于参与者报告跌倒的准确性。
研究记忆与跌倒报告之间的关系。
500 名年龄在 70-90 岁的社区居住成年人。
使用 Rey 听觉言语学习测试和 Trail Making 测试分别评估记忆和执行功能。使用生理概况评估(PPA)估计跌倒风险。使用每月跌倒日记和需要时的随访电话对跌倒进行前瞻性记录 12 个月。
Spearman 相关分析显示,跌倒与较差的执行功能、较差的 PPA 评分和较好的记忆显著相关。记忆力较好的人被归类为单次跌倒者和多次跌倒者的风险增加,但不包括报告的伤害作为定义的一部分。
良好的记忆似乎会影响社区居住的老年人对跌倒的记录,这可能反映了报告的偏差。在研究中,当将人群分为跌倒者和非跌倒者时,将受伤跌倒和多次跌倒相结合可能具有一定价值。
