背景：肺功能下降对健康的影响超出了可诊断的肺部疾病。因此，重要的是要了解可能影响肺功能即使是微小变化的因素，包括肥胖，身体健康和体育活动。本研究的目的是确定人体测量最有用的检查与肺功能的关联，并确定如何体力活动和身体素质的影响，这association.Methods：目前的研究使用的横截面数据4662名年龄在40-79岁的成年人从加拿大健康措施调查周期1和2。使用线性回归模型检查人体测量和肺功能测量（1秒用力呼气量[FEVi]和用力肺活量[FVC]）之间的相关性;比较模型之间的R-2值。身体素质和体力活动的条款被添加到模型和潜在的混淆assessed.Results：模型使用的总和5皮褶和腰围始终有最高的R-2值FEV 1和FVC，而模型使用体重指数始终有最低的R-2值FEV 1和FVC和男性和女性。体力活动和体能是腰围和肺功能指标之间关系的混杂因素。腰围仍然是一个显着的预测FVC，但不FEV 1调整体力活动或体能。结论：腰围是肺功能的一个重要预测因子。体力活动和体能应被视为人体测量指标和肺功能之间关系的潜在混杂因素。(C)2017由Elsevier Ltd.出版
Background: Decreased lung function has health impacts beyond diagnosable lung disease. It is therefore important to understand the factors that may influence even small changes in lung function including obesity, physical fitness and physical activity. The aim of this study was to determine the anthropometric measure most useful in examining the association with lung function and to determine how physical activity and physical fitness influence this association.Methods: The current study used cross-sectional data on 4662 adults aged 40-79 years from the Canadian Health Measures Survey Cycles 1 and 2. Linear regression models were used to examine the association between the anthropometric and lung function measures (forced expiratory volume in 1 s [FEVi] and forced vital capacity [FVC]); R-2 values were compared among models. Physical fitness and physical activity terms were added to the models and potential confounding was assessed.Results: Models using sum of 5 skinfolds and waist circumference consistently had the highest R-2 values for FEV1 and FVC, while models using body mass index consistently had among the lowest R-2 values for FEV1 and FVC and for men and women. Physical activity and physical fitness were confounders of the relationships between waist circumference and the lung function measures. Waist circumference remained a significant predictor of FVC but not FEV1 after adjustment for physical activity or physical fitness.Conclusions: Waist circumference is an important predictor of lung function. Physical activity and physical fitness should be considered as potential confounders of the relationship between anthropometric measures and lung function. (C) 2017 Published by Elsevier Ltd.
