Older adults commonly experience concurrent lower handgrip strength and sensory impairment. However, previous studies have analyzed the individual effects of either handgrip strength or sensory impairment on cognitive impairment. To address this gap, this study investigated the combined effects of handgrip strength and sensory impairment on cognitive impairment among older adults. In total, 2930 participants aged 65 and older were analyzed using 2014-2018 data from the Korean Longitudinal Study of Aging. Participants underwent assessments of handgrip strength (grip dynamometer), sensory impairment (self-reported responses), and cognitive impairment (Korean version of the Mini-Mental State Examination). Low handgrip strength, compared to normal handgrip strength, was associated with cognitive impairment. In participants with low handgrip strength, vision and hearing impairment were associated with cognitive impairment (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.06-1.75; OR 2.58, 95% CI 1.77-3.78, respectively) compared to those with normal handgrip strength. Participants with low handgrip strength and dual sensory impairment had the highest OR for cognitive impairment (OR 3.73, 95% CI 2.65-5.25). Due to the strong association of low handgrip strength and dual sensory impairment with cognitive impairment, people living with low handgrip strength and dual sensory impairment should be classified as a high-risk group for cognitive impairment and should be prioritized for interventions.
老年人通常同时存在手部握力下降和感觉障碍。然而，以前的研究分析了手部握力或感觉障碍对认知障碍的单独影响。为了解决这一差距，本研究调查了老年人手部握力和感觉障碍对认知障碍的综合影响。共有 2930 名 65 岁及以上的参与者使用 2014-2018 年韩国老龄化纵向研究的数据进行了分析。参与者接受了手部握力（握力测力计）、感觉障碍（自我报告的反应）和认知障碍（韩国版简易精神状态检查）的评估。与正常握力相比，低握力与认知障碍有关。在握力较低的参与者中，视力和听力障碍与认知障碍相关（比值比 [OR] 1.36，95%置信区间 [CI] 1.06-1.75；OR 2.58，95% CI 1.77-3.78），与握力正常的参与者相比。握力较低且双重感觉障碍的参与者认知障碍的比值比最高（OR 3.73，95% CI 2.65-5.25）。由于低握力和双重感觉障碍与认知障碍之间存在很强的关联，因此应将同时患有低握力和双重感觉障碍的人群归类为认知障碍的高危人群，并优先进行干预。
