Age, Body Mass Index (BMI) and flexibility are factors affecting foot posture, which is poorly understood in young adults. The objective of this study is to discover the relationships among these factors.
252 healthy participants (106 males, 146 females) between the ages of 18 and 25 were selected. BMI and the Foot Posture Index - 6 item version (FPI-6) were assessed, a Beighton score was obtained for each participant, and a lunge test was conducted.
Pronated feet (indicated by an FPI-6 score of 6+ (had a weak positive correlation with Beighton score (r=0.25, p= 0.05, 95% CI [0.01 to 0.47]) and a weak negative correlation with BMI (r=0.31, p = 0.01, 95% CI [-0.52 to -0.07]). Females had a higher prevalence of pronated feet (81.75%) than males (18.75%).
There is a mild relationship between ligament laxity and foot pronation, and females are more prone to have pronated feet than males. No correlation was found between body weight and pronated feet.
年龄、体重指数（BMI）和柔韧性是影响足弓的因素，而年轻人的足弓情况了解甚少。本研究旨在探讨这些因素之间的关系。
选择了 252 名年龄在 18 至 25 岁之间的健康参与者（106 名男性，146 名女性）。评估 BMI 和足弓指数-6 项（FPI-6），对每位参与者进行 Beighton 评分，并进行前弓步测试。
旋前足（FPI-6 评分 6+）与 Beighton 评分呈弱正相关（r=0.25，p=0.05，95%CI[0.01 至 0.47]），与 BMI 呈弱负相关（r=0.31，p=0.01，95%CI[-0.52 至-0.07]）。女性旋前足的患病率（81.75%）高于男性（18.75%）。
韧带松弛与足旋前之间存在轻度关系，女性比男性更容易出现旋前足。体重与旋前足之间无相关性。
