Few studies have examined the effects of health literacy on people at risk of developing dementia; its effects on the pathogenesis of subjective cognitive decline (SCD) are particularly unclear. This study aimed to clarify the relationship between health literacy and SCD in a population of healthy community-dwelling older adults. SCD status was assessed using the Cognitive Function domain of the Kihon Checklist (KCL-CF). Health literacy, in turn, was evaluated using the Communicative and Critical Health Literacy (CCHL) scale. Global cognitive function and depressive symptoms were evaluated using the Mini-Mental State Examination (MMSE) and a five-item version of the Geriatric Depression Scale (GDS-5), respectively. Participants who were suspected of having SCD were significantly older than their non-SCD peers, and scored significantly worse on the CCHL, MMSE, and GDS-5. In addition, SCD status was found to be associated with CCHL and GDS-5 scores, as well as age, according to a logistic regression analysis. These findings suggest that low health literacy is linked to SCD morbidity in healthy community-dwelling older adults and should prove useful in the planning of dementia prevention and intervention programs for this population.
很少有研究探讨健康素养对有患痴呆症风险人群的影响；其对主观认知下降（SCD）发病机制的影响尤其不清楚。本研究旨在阐明健康素养与健康社区居住老年人中SCD之间的关系。使用基宏检查表（KCL-CF）的认知功能领域评估SCD状态。反过来，使用沟通与批判性健康素养（CCHL）量表评估健康素养。分别使用简易精神状态检查表（MMSE）和老年抑郁量表五条目版（GDS-5）评估整体认知功能和抑郁症状。疑似患有SCD的参与者明显比未患SCD的同龄人年龄大，并且在CCHL、MMSE和GDS-5上的得分明显更差。此外，根据逻辑回归分析，发现SCD状态与CCHL和GDS-5得分以及年龄有关。这些发现表明，低健康素养与健康社区居住老年人的SCD发病率有关，并且在为该人群规划痴呆症预防和干预项目时应会有所帮助。
