A sedentary lifestyle, characterised by a lack of physical activity, negatively influences Body Mass Index (BMI). BMI may be related to the prevalence of flat feet. This study aims to observe the occurrence of flat feet in young children and determine its association with BMI. Additionally, it aims to analyse foot loading in the forefoot, midfoot and rearfoot. Dynamographic records of children (N = 142; age = 10.3 ± 0.21 years) were collected during walking, and foot-type evaluations were conducted using a force plate. A normal foot type was observed in 44% of children (BMI 16.0 ± 2.3 kg/m). Flat feet were observed in 54% of children (BMI 18.4 ± 4.3 kg/m). A high foot arch was observed in only 2% of children (BMI 16.0 ± 1.3 kg/m). Children with flat feet had higher BMI values than those with normal feet. The contact time and maximal vertical force in the forefoot and rearfoot were similar in children with normal and flat feet. Significantly higher pressure values were observed in the midfoot zone of children with flat feet. Regression analysis results showed that in children with flat feet, there is a decrease in forefoot loading and an increase in midfoot loading with increasing BMI. This trend was not observed in children with normal feet. We recommend incorporating exercise interventions at this age to prevent pain and promote willingness to engage in physical activity. Higher BMI values indicate an increased risk for the prevalence of flat feet.
以缺乏身体活动为特征的久坐不动的生活方式会对体重指数（BMI）产生负面影响。BMI可能与扁平足的患病率有关。本研究旨在观察幼儿扁平足的发生情况，并确定其与BMI的关联。此外，旨在分析前足、中足和后足的足部负荷情况。在儿童（N = 142；年龄 = 10.3 ± 0.21岁）行走过程中收集动态记录，并使用测力板进行足型评估。44%的儿童（BMI 16.0 ± 2.3 kg/m²）观察到正常足型。54%的儿童（BMI 18.4 ± 4.3 kg/m²）观察到扁平足。仅2%的儿童（BMI 16.0 ± 1.3 kg/m²）观察到高足弓。扁平足儿童的BMI值高于正常足儿童。正常足和扁平足儿童在前足和后足的接触时间和最大垂直力相似。在扁平足儿童的中足区域观察到明显更高的压力值。回归分析结果表明，在扁平足儿童中，随着BMI的增加，前足负荷减少，中足负荷增加。在正常足儿童中未观察到这种趋势。我们建议在这个年龄段纳入运动干预措施，以预防疼痛并促进参与体育活动的意愿。较高的BMI值表明扁平足患病率增加的风险。
