OBJECTIVES
To determine the prevalence of frailty in patients with chronic lung diseases.
METHODS
We studied 120 patients with chronic lung disease using Fried's criteria (gait speed, weight loss, exhaustion, grip strength, and physical activity).
RESULTS
The study population (56% women) had a mean age of 64 ± 13 years, mean body mass index of 31± 9 kg/m(2), and a mean FEV(1) (forced expiratory volume in 1 second) of 60% ± 25% of predicted. The average gait speed was 52.1 ± 14.3 m/min; 18% were frail, 64% prefrail, and 18% robust. Gait speed correlated with frailty status and decreased as frailty worsened (57 m/min in robust subjects and 41 m/min in frail subjects). Slow gait speeds (<60 m/min) had a 95% sensitivity and 34% specificity to predict frailty.
CONCLUSIONS
Patients with chronic lung disease frequently meet Fried's criteria for frailty. Gait speed can be used to screen these patients to determine if a more detailed evaluation is needed.
目的
确定慢性肺部疾病患者中衰弱的患病率。
方法
我们使用弗里德标准（步速、体重减轻、疲惫、握力和体力活动）对120例慢性肺部疾病患者进行了研究。
结果
研究人群（56%为女性）的平均年龄为64±13岁，平均体重指数为31±9kg/m²，平均第一秒用力呼气量（FEV₁）为预测值的60%±25%。平均步速为52.1±14.3米/分钟；18%为衰弱，64%为衰弱前期，18%为健康。步速与衰弱状态相关，且随着衰弱程度加重而降低（健康受试者为57米/分钟，衰弱受试者为41米/分钟）。步速慢（<60米/分钟）预测衰弱的敏感度为95%，特异度为34%。
结论
慢性肺部疾病患者经常符合弗里德衰弱标准。步速可用于筛查这些患者，以确定是否需要进行更详细的评估。
