Overweight (OW) and childhood obesity (OB) may cause foot problems and affect one's ability to perform physical activities. The study aimed to analyze the differences in descriptive characteristics, foot type, laxity, foot strength, and baropodometric variables by body mass status and age groups in children and, secondly, to analyze the associations of the BMI with different physical variables by age groups in children.
A descriptive observational study involving 196 children aged 5-10 years was conducted. The variables used were: type of foot, flexibility, foot strength and baropodometric analysis of plantar pressures, and stability by pressure platform.
Most of the foot strength variables showed significant differences between the normal weight (NW), OW and OB groups in children aged between 5 and 8. The OW and OB groups showed the highest level of foot strength. In addition, the linear regression analyses showed, in children aged 5 to 8 years, a positive association between BMI and foot strength (the higher the BMI, the greater the strength) and negative association between BMI and stability (lower BMI, greater instability).
Children from 5 to 8 years of age with OW and OB show greater levels of foot strength, and OW and OB children from 7 to 8 years are more stable in terms of static stabilometrics. Furthermore, between 5 and 8 years, having OW and OB implies having more strength and static stability.
超重（OW）和儿童肥胖（OB）可能导致足部问题，并影响一个人的身体活动能力。本研究旨在分析儿童按体重状况和年龄组划分的描述性特征、足型、松弛度、足部力量和足底压力测量变量的差异，其次，分析儿童按年龄组划分的体重指数（BMI）与不同身体变量之间的关联。
进行了一项描述性观察研究，涉及196名5至10岁的儿童。所使用的变量包括：足型、柔韧性、足部力量以及足底压力的足底压力测量分析，以及通过压力平台进行的稳定性分析。
在5至8岁的儿童中，大多数足部力量变量在正常体重（NW）、超重和肥胖组之间存在显著差异。超重和肥胖组的足部力量水平最高。此外，线性回归分析显示，在5至8岁的儿童中，BMI与足部力量呈正相关（BMI越高，力量越大），BMI与稳定性呈负相关（BMI越低，不稳定性越大）。
5至8岁超重和肥胖的儿童表现出更高水平的足部力量，7至8岁超重和肥胖的儿童在静态稳定测量方面更稳定。此外，在5至8岁之间，超重和肥胖意味着具有更强的力量和静态稳定性。
