TAP 导读: Frailty in older adults: evidence for a phenotype

Fried等以体重下降、耗竭、低握力、慢步速和低活动五项构建衰弱表型,三项及以上定义为衰弱。该表型与后来死亡、住院和日常活动能力下降相关,为识别老年脆弱状态提供了可操作框架;它不是直接测量扰动后的动态恢复。

研究发现

Fried等以体重下降、耗竭、低握力、慢步速和低活动五项构建衰弱表型,三项及以上定义为衰弱。该表型与后来死亡、住院和日常活动能力下降相关,为识别老年脆弱状态提供了可操作框架;它不是直接测量扰动后的动态恢复。

范围与局限

CHS的5,317名社区成年人,年龄≥65岁;两个入组队列,衰弱患病率6.9%。

观察性设计、既有可用变量、部分自报指标及特定疾病排除限制推广。表7三年跌倒HR=1.29(95%CI 1.00—1.68),P=.054,不能把所有结局都称为显著。性别、体型相关阈值应核对原文后再考虑应用。

研究人群与样本

CHS的5,317名社区成年人,年龄≥65岁;两个入组队列,衰弱患病率6.9%。

暴露或干预

五项表型;1—2项为中间状态,≥3项为衰弱,与非衰弱者比较。

观察结局

三年调整死亡HR=2.24(1.51—3.33),住院1.29(1.09—1.54),ADL恶化1.98(1.54—2.55);跌倒结果另列。

时间范围

两个入组队列分别随访7年与4年;上述表7风险比较为三年。

研究资金来源

NHLBI/NIH的多项Cardiovascular Health Study合同支持,详见原文。

研究利益关系

独立利益声明尚未核实。

导读范围

原刊PDF第M146—M154页;性别、BMI和身高分层的阈值附录尚待逐项核读。
