The purpose of this study was to develop a screening questionnaire for frailty based on the Fried frailty phenotype (FFP) in community-dwelling older adults.
Cross-sectional data analysis of a cohort study.
The study used baseline data from the Korean Frailty and Aging Cohort Survey, a multicenter longitudinal study undertaken in 10 urban, rural, and suburban communities in Korea between 2016 and 2017. A total of 2917 older adults aged 70 to 84 years were included in the analysis, who were administered questionnaires and physical function tests.
Gait speed and grip strength were measured, and all participants completed the International Physical Activity Questionnaire and answered questions about weight loss and exhaustion based on FFP.
Five questions were chosen to screen for FFP: fatigue (exhaustion), resistance (weakness), ambulation (slowness), inactivity, and loss of weight. The Frailty Phenotype Questionnaire (FPQ; range of 0-5) was well correlated with the Fried frailty scale (range of 0-5) (r = 0.643; P < .001). Frailty based on the FPQ score (≥3 of 5) showed satisfactory diagnostic accuracy for FFP (area under the curve = 0.89), with high sensitivity (81.7%) and specificity (82.5%).
The FPQ is a highly accurate screening tool for FFP in community-dwelling older adults.
本研究旨在基于社区居住的老年人 Fried 衰弱表型（FFP）开发一种衰弱筛查问卷。
队列研究的横断面数据分析。
本研究使用了韩国衰弱和衰老队列研究的基线数据，这是一项于 2016 年至 2017 年在韩国 10 个城市、农村和郊区社区进行的多中心纵向研究。共纳入 2917 名年龄在 70 至 84 岁的老年人，他们接受了问卷调查和身体功能测试。
测量了步速和握力，所有参与者都完成了国际体力活动问卷，并根据 FFP 回答了关于体重减轻和疲劳的问题。
选择了五个问题来筛查 FFP：疲劳（乏力）、抵抗力（虚弱）、活动能力（缓慢）、不活动和体重减轻。衰弱表型问卷（FPQ；范围 0-5）与 Fried 衰弱量表（范围 0-5）具有良好的相关性（r=0.643；P<0.001）。基于 FPQ 得分（≥3 分）的衰弱对 FFP 具有令人满意的诊断准确性（曲线下面积=0.89），具有较高的敏感性（81.7%）和特异性（82.5%）。
FPQ 是社区居住的老年人 FFP 的一种高度准确的筛查工具。
