Abstract

Background

Cognitive impairment prevalence is rising with population aging. This study examined the relationship between handgrip strength and gait speed with cognitive impairment and performance in older adults.

Methods

This cross-sectional study used baseline data from Birjand Longitudinal Aging Study (BLAS), including 1347 older adults. Cognitive function was evaluated using the six-item Cognitive Impairment Test (6-CIT). Gait speed was measured over six meters, and grip strength was assessed with hand dynamometers.

Results

After adjusting for potential confounders, the association between low handgrip strength and cognitive impairment lost its significance (relative risk ratio (RRR) = 1.07, 95% CI: 0.70, 1.63). However, low gait speed remained significantly associated with dementia (RRR = 1.92, 95% CI: 1.23, 3.01) after adjusting for age, sex, education, body mass index (BMI), hypertension, and depressive symptoms.

Conclusion

Low gait speed is significantly associated with dementia, highlighting the importance of incorporating physical function measures into dementia risk assessments.

伊朗老年人握力和步态速度与认知障碍的关系：Birjand纵向衰老研究

背景随着人口老龄化，认知障碍患病率呈上升趋势。本研究考察了握力和步态速度与老年人认知障碍和表现之间的关系。方法本横断面研究使用来自Birjand纵向衰老研究（BLAS）的基线数据，包括1347名老年人。采用六项认知障碍测验（6-CIT）评估认知功能。在6米的距离内测量步态速度，用手测力仪评估握力。结果调整潜在混杂因素后，低握力与认知功能障碍之间的相关性失去了显著性（相对风险比(RRR) = 1.07, 95% CI: 0.70, 1.63）。然而，在调整了年龄、性别、教育程度、体重指数（BMI）、高血压和抑郁症状后，低步速仍与痴呆显著相关（RRR = 1.92, 95% CI: 1.23, 3.01）。结论低步速与痴呆显著相关，强调了将身体功能指标纳入痴呆风险评估的重要性。
