To investigate the association of the Japan Science and Technology Agency Index of Competence with physical and cognitive functions in community-dwelling older adults.
This study used the data of 565 community-dwelling adults aged ≥65 years (mean age: 74.3 ± 5.2 years) from the Kasama Health Checkup for Longevity survey in Japan. The Japan Science and Technology Agency Index of Competence was used to comprehensively evaluate the higher-level functional capacity and subscale functional capacity: technology usage, information practice, life management and social engagement. Physical functions were assessed using grip strength, the five-repetition sit-to-stand test, 5-m habitual walking test, one-leg standing test and hand working test with a pegboard. Cognitive functions were evaluated using the Five-Cog test consisting of attention, memory ability, visuospatial function, language ability and reasoning ability. Multiple regression analysis was conducted to examine the associations between total Japan Science and Technology Agency Index of Competence score and physical and cognitive functions.
After adjusting for potential confounders, the total Japan Science and Technology Agency Index of Competence score was favorably associated with static balance ability (β = 0.09; B = 0.01; 95% confidence interval: 0.00-0.02), lower limb strength (β = -0.19; B = -0.29; 95% confidence interval: -0.41 to -0.16), walking ability (β = -0.15; B = -0.67; 95% confidence interval: -1.05 to -0.30), hand dexterity (β = -0.13; B = -0.08; 95% confidence interval: -0.14 to -0.03) and overall cognitive function (β = 0.28; B = 0.04; 95% confidence interval: 0.03-0.05).
Physical and cognitive functions are important for maintaining higher-level functional capacity. Geriatr Gerontol Int 2022; 22: 753-758.
探讨日本科学技术振兴机构能力指数与社区老年人的身体和认知功能之间的关联。
本研究使用了来自日本笠间长寿健康检查调查的 565 名年龄在 65 岁及以上（平均年龄：74.3±5.2 岁）的社区居住成年人的数据。日本科学技术振兴机构能力指数用于全面评估更高层次的功能能力和子功能能力：技术使用、信息实践、生活管理和社会参与。身体功能通过握力、五次重复坐站测试、5 米习惯性步行测试、单腿站立测试和使用钉板的手工作测试进行评估。认知功能通过包括注意力、记忆能力、视空间功能、语言能力和推理能力在内的五认知测试进行评估。进行多元回归分析以检验日本科学技术振兴机构能力指数总分与身体和认知功能之间的关系。
在调整了潜在混杂因素后，日本科学技术振兴机构能力指数总分与静态平衡能力（β=0.09；B=0.01；95%置信区间：0.00-0.02）、下肢力量（β=-0.19；B=-0.29；95%置信区间：-0.41 至-0.16）、行走能力（β=-0.15；B=-0.67；95%置信区间：-1.05 至-0.30）、手部灵巧度（β=-0.13；B=-0.08；95%置信区间：-0.14 至-0.03）和整体认知功能（β=0.28；B=0.04；95%置信区间：0.03-0.05）呈正相关。
身体和认知功能对于维持更高层次的功能能力很重要。
