The aim of this study is to examine the relationship between obesity and foot posture in children.
This cross-sectional study is based on a sample population of 1798 schoolchildren (873 boys and 925 girls) aged between 6 and 12 years. The height and weight of each subject was measured and the body mass index (BMI) was calculated. Foot posture was described by means of the foot posture index (FPI). The differences among various foot postures in relation to BMI, for the total sample, were tested using the Games-Howell test. In addition, cross tabulation for different gender groups and BMI categories was applied and tested using χ .
The mean BMI was 18.94 (standard deviation (SD) 3.65 kg/m ) in the boys and 18.90 (SD 3.64 kg/m ) in the girls, and the FPI was 3.97 (SD 2.98) in the boys and 3.68 (SD 2.86) in the girls. The FPI results show that among the boys aged 6 years, the right foot was more pronated than among the girls (FPI 4.8-4.1, P = 0.034), while among the boys aged 7 years, this was true for the left foot (4.4-3.7, P = 0.049). For the other ages, there were no significant differences in the FPI between the sexes. There were no significant differences between the value, or categories, of BMI and the FPI in the different age groups.
In children aged between 6 and 12 years, body mass does not appear to have an important bearing on static foot posture. Furthermore, the variables gender and age are of scant importance in determining foot posture in children.
本研究旨在探讨儿童肥胖与足部姿势之间的关系。
本横断面研究基于1798名6至12岁学童（873名男孩和925名女孩）的样本群体。测量了每个受试者的身高和体重，并计算了体重指数（BMI）。通过足部姿势指数（FPI）描述足部姿势。使用Games-Howell检验测试总样本中不同足部姿势与BMI之间的差异。此外，应用不同性别组和BMI类别的交叉表并使用χ检验。
男孩的平均BMI为18.94（标准差（SD）3.65kg/m），女孩为18.90（SD 3.64kg/m），男孩的FPI为3.97（SD 2.98），女孩为3.68（SD 2.86）。FPI结果显示，在6岁男孩中，右脚比女孩更内旋（FPI 4.8 - 4.1，P = 0.034），而在7岁男孩中，左脚情况相同（4.4 - 3.7，P = 0.049）。对于其他年龄组，两性之间的FPI没有显著差异。不同年龄组的BMI值或类别与FPI之间没有显著差异。
在6至12岁的儿童中，体重似乎对静态足部姿势没有重要影响。此外，性别和年龄变量在确定儿童足部姿势方面重要性不大。
