Arch structure and arch function play an important role in maintaining balance, bearing body weight, and absorbing ground reaction forces. However, arch structure and arch function are known to vary extensively and may be affected by factors such as gender, age, and obesity. Therefore, the purpose of this study was to examine the influence of gender, age, and body mass index (BMI) on arch height and arch stiffness. A total of 173 participants (aged 57.60 ± 11.19 years, mean BMI 25.12 ± 3.93 kg/m) participated in this cross-sectional study. A 3-dimensional laser scanner was used to measure foot structure information in each subject, from which arch height and arch stiffness were calculated. The results showed that women had low-arched feet compared with men (p = .001), and no arch stiffness difference was found. Older individuals tended to have a stiffer arch than middle-aged and younger individuals (p < .05), and no arch height difference was found. BMI had an impact on arch height (p < .05) but not arch stiffness. Finally, a weak positive relationship existed between arch height and arch stiffness (r = 0.32, p < .01). The findings suggest that gender, age, and obesity have a certain impact on arch structure and arch stiffness. Figuring out the relationship between these factors and arch structure may be helpful in understanding the bases of foot deformity and foot dysfunction.
足弓结构和功能在维持平衡、承载体重和吸收地面反作用力方面起着重要作用。然而，足弓结构和功能变化广泛，可能受到性别、年龄和肥胖等因素的影响。因此，本研究旨在探讨性别、年龄和体重指数（BMI）对足弓高度和足弓刚度的影响。共有 173 名参与者（年龄 57.60±11.19 岁，平均 BMI 25.12±3.93kg/m）参与了这项横断面研究。使用三维激光扫描仪测量每位受试者的足部结构信息，从中计算出足弓高度和足弓刚度。结果表明，女性的足弓高度低于男性（p=0.001），但足弓刚度无差异。年龄较大的个体比中年和年轻个体的足弓更僵硬（p<0.05），且足弓高度无差异。BMI 对足弓高度有影响（p<0.05），但对足弓刚度没有影响。最后，足弓高度与足弓刚度之间存在弱正相关关系（r=0.32，p<0.01）。这些发现表明，性别、年龄和肥胖对足弓结构和足弓刚度有一定影响。了解这些因素与足弓结构之间的关系，可能有助于理解足部畸形和足部功能障碍的基础。
