背景：年龄和生活方式相关的呼吸和身体功能变化影响咳嗽强度。然而，在老年人中，与咳嗽强度相关的主要因素仍不清楚。本研究是对社区老年人咳嗽强度的影响因素以及咳嗽强度与呼吸功能、身体表现、身体活动和久坐行为之间关系的初步调查。方法：通过使用加速计和其他工具，我们评估了咳嗽峰流量（CPF）、FVC、最大吸气压（P-Imax）、最大呼气压（P-Emax）、胸壁和腹壁活动度（呼吸运动量表）、体能（定时起身和行走测试和30秒椅子站立测试），体力活动（步骤，和机车和非机车中度到剧烈的身体活动），和久坐行为（久坐时间）在65个社区居住的老年人（25名男性和40名女性）没有气流限制。结果：26%的受试者（17/65）CPF降低（< 240 L/min）。与CPF未降低的受试者相比，CPF降低的受试者的FVC、P-Imax、PEmax、胸腹壁活动度、体能和运动性中度至剧烈体力活动显著降低。CPF与呼吸功能变量（FVC、P-Imax、P-Emax和呼吸运动量表）和体能之间的显著相关性为弱至中度。在校正性别、年龄和身高的多元回归分析中，FVC和P-Imax与CPF独立相关。受试者工作特征分析表明，FVC和P-Imax检测CPF降低的灵敏度相当好。结论：我们的研究结果分析表明，FVC和P-Imax与CPF相关，并提供了初步证据，支持社区居住的老年人保持和改善咳嗽强度的策略。
BACKGROUND: Age- and lifestyle-related changes in respiratory and physical function affect cough strength. However, in older adults, the main factors that relate to cough strength remain unclear. This study was a preliminary investigation of factors that contribute to cough strength and the relationships between cough strength and respiratory function, physical performance, physical activity, and sedentary behavior in community-dwelling older adults. METHODS: By using accelerometers and other tools, we assessed cough peak flow (CPF), FVC, maximum inspiratory pressure (P-Imax), maximum expiratory pressure (P-Emax), chest and abdominal wall mobility (breathing movement scale), physical performance (Timed Up and Go test and 30-s chair stand test), physical activity (steps, and locomotive and non-locomotive moderate-to-vigorous physical activity), and sedentary behavior (sedentary time) in 65 community-dwelling older adults (25 males and 40 females) without air-flow limitation. RESULTS: Twenty-six percent of the subjects (17/65) had reduced CPF (< 240 L/min). The subjects with reduced CPF had significantly lower FVC, P-Imax, PEmax, chest and abdominal wall mobility, physical performance, and locomotive moderate-to-vigorous physical activity compared with those with non-reduced CPF. Significant correlations between CPF and variables of respiratory function (FVC, P-Imax, P-Emax, and breathing movement scale) and physical performance were weak to moderate. FVC and P-Imax were independently associated with CPF during the multiple regression analysis adjusted for sex, age, and height. The receiver operating characteristic analysis showed that FVC and P-Imax had fair-to-good sensitivity for detecting reduced CPF. CONCLUSIONS: Analysis of our results indicated that FVC and P-Imax were related to CPF and provided preliminary evidence that supported strategies for preserving and improving cough strength in community-dwelling older adults.
