Abstract
Investigation of the association between physical frailty and cognitive performance through spatial navigation is important to enable the identification of individuals with cognitive impairment and physical comorbidity.
Objective: To analyze the association between spatial navigation and frailty in frail and pre-frail institutionalized older adults.
Methods: Forty older people of both sexes, aged 60 years or over, residing in four Brazilian Long-Term Care Facilities (LTCFs) participated in this study. The following tests were applied: Mini-Mental State Examination (MMSE), 2.44m Timed Up and Go, Floor Maze Test (FMT), and Fried's frailty criteria. For data analysis, the Mann-Whitney and independent t-tests were used to compare the groups (frail x pre-frail), principal component analysis was used to explore the main variables related to the data variance, and binary logistic regression to estimate associations.
Results: There was a significant difference in performance in the FMT immediate maze time (IMT) (p=0.02) and in the delayed maze time (DMT) (p=0.009) between the pre-frail and frail older adults. An association between FMT DMT performance and frailty was found, showing that older people with shorter times on the DMT (better performance) had approximately four times the chance of not being frail (odds ratio - OR=4.219, 95% confidence interval - 95%CI 1.084-16.426, p=0.038).
Conclusion: Frailty is associated with impaired spatial navigation ability in institutionalized older adults, regardless of gait speed performance.
通过空间导航研究身体虚弱和认知表现之间的关系对于识别认知障碍和身体合并症的个体具有重要意义。目的:分析体弱多病和体弱多病前老年人空间导航与衰弱的关系。方法:40名年龄在60岁或以上的男女老年人，居住在四个巴西长期护理机构(ltcf)参加了这项研究。采用以下测试:迷你精神状态测试(MMSE)、2.44m Timed Up and Go、地板迷宫测试(FMT)和Fried虚弱标准。对于数据分析，采用Mann-Whitney检验和独立t检验比较各组(虚弱x前虚弱)，采用主成分分析探讨与数据方差相关的主要变量，并采用二元逻辑回归估计相关性。结果:体弱前老年人和体弱老年人在FMT即时迷宫时间(IMT)和延迟迷宫时间(DMT)上的表现有显著差异(p=0.009)。FMT DMT表现与虚弱之间存在关联，显示DMT时间较短(表现较好)的老年人不虚弱的机会约为四倍(优势比- OR=4.219, 95%置信区间- 95% ci 1.084-16.426, p=0.038)。结论:无论步态速度如何，老年人的虚弱都与空间导航能力受损有关。
