Little is known about the association between physical activity and lung function in childhood. We conducted a survey including parental reports of the child's participation in physical activity and measurements of lung function. The associations between physical activity and lung function were estimated by linear regression analysis adjusting for potential confounders in 2,537 children (9 to 10 years). Using the linear model in exploring the effect of physical activity on lung function with those who were physical active less than once a week as the reference category, showed that forced expiratory volume in 1 s (FEV1) was highest among those who were physical active > or = 4 times a week also when adjusting for potential confounders (p = .02). FEV1 increased with 70 ml. A similar pattern was present for forced vital capacity (FVC; p = .002). The present study suggested that lung function was highest in highly physical active children age 9 to 10 years. The implications are that exercise may influence lung function, but these findings need to be confirmed using a longitudinal study design.
关于儿童期身体活动与肺功能之间的关联，人们了解甚少。我们开展了一项调查，其中包括家长报告孩子参与身体活动的情况以及肺功能测量。通过线性回归分析对2537名儿童（9至10岁）的潜在混杂因素进行校正后，估计身体活动与肺功能之间的关联。以每周身体活动少于一次的儿童为参照类别，使用线性模型探究身体活动对肺功能的影响，结果显示，在对潜在混杂因素进行校正后，每周身体活动≥4次的儿童的1秒用力呼气容积（FEV1）也是最高的（p = 0.02）。FEV1增加了70毫升。用力肺活量（FVC；p = 0.002）也呈现出类似的模式。本研究表明，9至10岁身体活动水平高的儿童肺功能最佳。这意味着运动可能会影响肺功能，但这些发现需要通过纵向研究设计加以证实。
