Gait speed (GS) is a predictor of negative outcomes in older adults and in those in risk to develop cognitive impairment; as such, it has been associated with dementia. Studies in Latin-American older adults showing this association are scarce. This study aimed to evaluate the relationship between GS and dementia in a representative sample of Colombian older adults.
This study is a secondary analysis from the Survey on Health, Well-Being, and Aging, SABE (from initials in Spanish: Salud, Bienestar & Envejecimiento) Colombia's survey conducted in 2015 with a sample of 23,694 elderly adults aged 60 years or older.
A total of 19,470 participants from the SABE Colombia survey were available for analysis. The multivariate analysis shows that dementia was associated with slow GS (PR 2.39; CI 1.91-3.01) independently to the other variables (p < 0.001). Similarly, GS as a continuous variable shows a statistically significant association with dementia in the adjusted analysis (OR 0.06; CI 0.04-0.09; p < 0.001).
Dementia was associated with slow GS. This finding provides evidence to include GS as a complementary parameter in the assessment of Colombian elderly adults.
步态速度（GS）是老年人和有认知障碍风险人群负面结果的预测指标；因此，它与痴呆有关。在拉丁美洲老年人中进行的研究表明存在这种关联，但研究较少。本研究旨在评估哥伦比亚代表性老年人群体中 GS 与痴呆之间的关系。
本研究是对 2015 年开展的健康、幸福和老龄化调查（SABE，源自西班牙语：Salud，Bienestar & Envejecimiento）的二次分析，该调查的样本为 23694 名年龄在 60 岁及以上的老年人。
共有 19470 名 SABE 哥伦比亚调查参与者可用于分析。多变量分析表明，痴呆与 GS 缓慢（PR 2.39；CI 1.91-3.01）独立相关，与其他变量无关（p < 0.001）。同样，GS 作为连续变量在调整分析中与痴呆呈显著统计学关联（OR 0.06；CI 0.04-0.09；p < 0.001）。
痴呆与 GS 缓慢有关。这一发现为将 GS 作为哥伦比亚老年人评估的补充参数提供了证据。
