[Purpose] The purpose is to verify the effectiveness of the 2-step test in predicting cognitive decline in elderly individuals. [Subjects and Methods] One hundred eighty-two participants aged over 65 years underwent the 2-step test, cognitive function tests and higher level competence testing. Participants were classified as Robust, <1.3, and <1.1 using criteria regarding the locomotive syndrome risk stage for the 2-step test, variables were compared between groups. In addition, ordered logistic analysis was used to analyze cognitive functions as independent variables in the three groups, using the 2-step test results as the dependent variable, with age, gender, etc. as adjustment factors. [Results] In the crude data, the <1.3 and <1.1 groups were older and displayed lower motor and cognitive functions than did the Robust group. Furthermore, the <1.3 group exhibited significantly lower memory retention than did the Robust group. The 2-step test was related to the Stroop test (β: 0.06, 95% confidence interval: 0.01-0.12). [Conclusion] The finding is that the risk stage of the 2-step test is related to cognitive functions, even at an initial risk stage. The 2-step test may help with earlier detection and implementation of prevention measures for locomotive syndrome and mild cognitive impairment.
[目的]目的是验证两步试验在预测老年人认知衰退方面的有效性。[对象与方法]182名65岁以上参与者接受了两步试验、认知功能测试和高级能力测试。根据两步试验的机车综合征风险阶段标准，将参与者分为强健组、<1.3组和<1.1组，对组间变量进行比较。此外，以两步试验结果为因变量，年龄、性别等为调整因素，采用有序逻辑回归分析将认知功能作为三组中的自变量进行分析。[结果]在原始数据中，<1.3组和<1.1组比强健组年龄更大，运动和认知功能更低。此外，<1.3组的记忆保持能力明显低于强健组。两步试验与斯特鲁普试验相关(β: 0.06, 95%置信区间: 0.01 - 0.12)。[结论]研究结果表明，即使在初始风险阶段，两步试验的风险阶段也与认知功能相关。两步试验可能有助于早期发现和实施针对机车综合征和轻度认知障碍的预防措施。
