稳定期慢性阻塞性肺疾病病人握力水平现状及其影响因素分析

Status quo of grip strength of patients with stable chronic obstructive pulmonary disease and its influencing factors

[目的]调查稳定期慢性阻塞性肺疾病(COPD)病人握力水平,并探讨其影响因素。[方法]采用一般资料调查表、握力器、身体成分分析仪等对96例稳定期COPD病人进行相关检测。[结果]稳定期COPD病人握力水平较同龄正常老年人低,性别、年龄、吸烟史以及呼吸困难指数对握力水平有影响;控制变量年龄、性别后,握力水平与疾病相关指标[第一秒用力呼气容积占预计值的百分比、6min步行距离、体重指数、多因素分级系统(BODE)指数以及呼吸困难指数]相关(P<0.05或P<0.01),性别、年龄、6min步行距离可以解释握力水平的38.8%的变异量。[结论]稳定期COPD病人握力水平较正常老年人群低,其与疾病相关指标有一定相关性,临床工作者可参考握力测试结果快速评估病人的功能状态。

Objective： To investigate the grip strength of patients with stable chronic obstructive pulmonary disease （COPD） and probe into its influencing factors. Methods： A total of 96 stable COPD patients were examined by general data questionnaire,grip device and body composition analyzer. Results： The grip strength of stable COPD patients was lower than that of normal elderly people of the same age.Gender,age,smoking history and mMRC were the influencing factors of grip strength.After controlled variable factors of age and sex,grip strength level were associated with the disease related indexes（ P 〈0.05 or P 〈0.01）,such as PEV1/pred,6MWD,body mass index,BODE index and mMRC.Gender,age,6MWD could explain 38.8% variation of grip strength level. Conclusion： The grip strength of stable COPD patients was lower than that of normal elderly.It had a certain correlation with disease related indexes.Clinician could quickly assess the functional status of the patient based on the results of the grip strength test.
