The present analysis formed part of the population study of Estonian school-children and was undertaken in order to examine the relationships between lung function variables, standing and sitting height. We measured forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), peak expiratory flow and forced expiratory flows when 50 and 75% of FVC had been exhaled, and anthropometric indices in 645 healthy schoolchildren, aged 6-18 years. The growth spurt in standing and sitting height occurred between the ages of 11 and 13 years in girls, and 13 and 15 years in boys. Growth spurts of lung parameters occurred during the same periods. FVC and FEV1 showed close correlations (r = 0.89-0.94) with all anthropometric parameters and age, whereas correlation coefficients for the flows were less close (r = 0.65-0.88). In boys, correlations between sitting height and lung function variables were greater than those with standing height. Using stepwise regression analysis, in boys sitting height was selected in all lung function parameters, and in girls sitting height was never selected. We conclude that there is a very close correlation between sitting height and lung function variables. The use of sitting height in parallel with standing height in predicted values for Estonian schoolchildren would make the values more exact.
本分析是爱沙尼亚学龄儿童人群研究的一部分，旨在研究肺功能变量、身高与坐高之间的关系。我们测量了645名6至18岁健康学龄儿童的用力肺活量（FVC）、第1秒用力呼气量（FEV1）、呼气峰值流速以及呼出FVC的50%和75%时的用力呼气流量，以及人体测量指标。女孩身高的快速增长发生在11至13岁之间，男孩则在13至15岁之间。肺参数的快速增长也发生在同一时期。FVC和FEV1与所有人体测量参数和年龄均显示出密切相关性（r = 0.89 - 0.94），而流量的相关系数则相对较低（r = 0.65 - 0.88）。在男孩中，坐高与肺功能变量之间的相关性大于与身高的相关性。通过逐步回归分析，在男孩中，所有肺功能参数均选择了坐高，而在女孩中则从未选择坐高。我们得出结论，坐高与肺功能变量之间存在非常密切的相关性。对于爱沙尼亚学龄儿童，在预测值中同时使用坐高和身高将使预测值更加准确。
