Cognitive frailty, a condition characterized by physical frailty with cognitive impairment, is emerging as a determinant of adverse health outcomes in older adults. However, its prevalence and correlation with associated factors are unknown in the aging population of Korea.
To estimate the prevalence of cognitive frailty and identify factors associated with it among older Korean adults.
A secondary analysis was performed using the Korean Longitudinal Study of Aging seventh survey dataset collected in 2018. Multinomial logistic regression analyses were conducted to examine the association between cognitive frailty and demographic, psychosocial, oral health and physical function factors. Individuals aged ≥65 years and without dementia were included (N = 1024). Participants were classified into four groups based on the presence or absence of physical frailty and mild cognitive impairment. This article is executed in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement.
The prevalence of cognitive frailty in the study sample was 11.2%. The results of multinomial logistic regression showed that advanced age, being female, lower education levels, heart disease, arthritis or rheumatoid arthritis, underweight, depression, non-social activity, poor oral health and functional limitation were significantly associated with cognitive frailty.
Cognitive frailty is prevalent among community-dwelling older adults in Korea. The findings provide primary care providers with insights about effective strategies for identifying at-risk individuals and will guide the development of population-level interventions to prevent or delay the onset of physical frailty and cognitive impairment in older adults.
The findings provide practical information to healthcare providers for identifying cognitive frailty in older adults. The risk factors of cognitive frailty, such as psychosocial, oral health, and physical function factors, should be thoroughly monitored for older adults. Health personnel working in primary care have a critical role in identifying risk and beneficial factors and promoting preventative strategies that enhance health outcomes.
认知脆弱是一种以身体脆弱伴认知障碍为特征的疾病，它正在成为影响老年人健康的一个重要因素。然而，在韩国的老年人群中，其流行程度及其与相关因素的相关性尚不清楚。
评估认知脆弱在韩国老年人群中的流行程度，并确定与之相关的因素。
利用 2018 年韩国老龄化纵向研究第七次调查数据集进行二次分析。采用多项逻辑回归分析方法，研究认知脆弱与人口统计学、心理社会、口腔健康和身体功能因素之间的关系。纳入年龄≥65 岁且无痴呆的个体（N=1024）。根据是否存在身体脆弱和轻度认知障碍，将参与者分为四组。本研究按照《观察性研究的报告质量（STROBE）声明》进行。
研究样本中认知脆弱的患病率为 11.2%。多变量逻辑回归分析结果显示，高龄、女性、低教育水平、心脏病、关节炎或类风湿性关节炎、体重不足、抑郁、非社交活动、口腔健康状况差和功能受限与认知脆弱显著相关。
认知脆弱在韩国社区居住的老年人中较为普遍。研究结果为初级保健提供者提供了有关识别高危个体的有效策略的见解，并将指导制定针对人口的干预措施，以预防或延缓老年人身体脆弱和认知障碍的发生。
研究结果为医疗保健提供者识别老年人的认知脆弱提供了实用信息。认知脆弱的危险因素，如心理社会、口腔健康和身体功能因素，应在老年人中进行彻底监测。在初级保健中工作的卫生人员在识别风险和有益因素以及促进增强健康结果的预防策略方面发挥着关键作用。
