This cross-sectional study examined the association between blood pressure and physical fitness in 1,369 children (81.5% of the eligible population) aged 8-10 years participating in the first phase of a primary intervention study with physical training. An inverse correlation between BP and physical fitness was demonstrated, and significant differences have been found between quartiles of distribution of physical fitness in girls with regard to systolic BP and in boys and girls with regard to diastolic BP respectively. Important determinants of physical fitness seemed to be dependent on confounding variables representing body mass index, height, heart rate and age. Our observations suggest that the contribution of confounding variables may explain the relationship between BP and physical fitness in childhood.
这项横断面研究调查了1369名8至10岁儿童（占符合条件人群的81.5%）的血压与身体素质之间的关联，这些儿童参与了一项体育锻炼初级干预研究的第一阶段。研究表明血压与身体素质呈负相关，并且分别在女孩的收缩压以及男孩和女孩的舒张压方面，发现了身体素质分布四分位数之间的显著差异。身体素质的重要决定因素似乎取决于代表体重指数、身高、心率和年龄的混杂变量。我们的观察结果表明，混杂变量的作用可能解释了儿童期血压与身体素质之间的关系。
