There are few studies on dietary patterns and frailty in Asians, and the results are controversial. Therefore, this study examined the association between dietary patterns and frailty in older Korean adults using the Korean Frailty and Aging Cohort Study (KFACS). The sample consisted of 511 subjects, aged 70-84 years, community-dwelling older people from the KFACS. Dietary data were obtained from the baseline study (2016-2017) using two nonconsecutive 24-h dietary recalls, and dietary patterns were extracted using reduced rank regression. Frailty was measured by a modified version of the Fried Frailty Phenotype (FFP) in both the baseline (2016) and the first follow-up study (2018). A logistic regression analysis was used to examine the association between dietary patterns and frailty status in 2018. The "meat, fish, and vegetables" pattern was inversely associated with pre-frailty (OR = 0.41, 95% CI = 0.21-0.81, for trend = 0.009) and exhaustion (OR = 0.41, 95% CI = 0.20-0.85, for trend = 0.020). The "milk" pattern was not significantly associated with frailty status or the FFP components. In conclusion, a dietary pattern with a high consumption of meat, fish, and vegetables was associated with a lower likelihood of pre-frailty.
亚洲人群中关于饮食模式与虚弱的研究较少，且结果存在争议。因此，本研究使用韩国虚弱与老龄化队列研究（KFACS）探讨了饮食模式与韩国 70-84 岁社区居住老年人虚弱之间的关联。该样本包括 511 名研究对象，他们来自 KFACS 的基线研究（2016-2017 年），使用了两次非连续的 24 小时膳食回忆法获取饮食数据，并使用降秩回归法提取饮食模式。虚弱通过改良版 Fried 虚弱表型（FFP）在基线（2016 年）和第一次随访研究（2018 年）中进行测量。使用逻辑回归分析来检验 2018 年饮食模式与虚弱状况之间的关联。“肉、鱼和蔬菜”模式与前期虚弱（OR = 0.41，95%CI = 0.21-0.81，趋势检验 = 0.009）和疲惫（OR = 0.41，95%CI = 0.20-0.85，趋势检验 = 0.020）呈负相关。“牛奶”模式与虚弱状况或 FFP 组成部分无显著关联。总之，摄入大量肉、鱼和蔬菜的饮食模式与较低的前期虚弱发生几率相关。
