青春期的标志是身体的变化，包括脚的变化。足部姿势指数（FPI-6）从其他足型分类方法中脱颖而出，有效、可靠、多维。然而，目前的文献根据不同的年龄组存在差异，对学龄儿童的规范性数据几乎没有整合，这主要是由于性别、年龄和体重指数（BMI）等因素的影响。因此，本研究根据年龄、性别和身体质量指数来评估青少年的足部姿势。该研究评估了来自巴西<s:1>圣保罗市安帕罗和佩德雷拉地区的1394名青少年。受试者赤脚置于木制底座上，每只脚按FPI-6标准进行评估。每个标准的评分范围为- 2到+2，旋后为负，旋前为正。最初使用Shapiro-Wilk检验评估数据的正态性，并计算描述性统计量。为了调查和比较FPI-6得分与年龄和体重指数的关系，采用方差分析（ANOVA），然后进行事后分析。为了比较FPI-6在性别方面的差异，我们使用了独立学生t检验。所有数据均采用SPSS 21.0版本进行分析，显著性水平为5%。男孩右脚得分高于女孩（p = 0.037）， BMI正常组得分高于肥胖组（p = 0.001）。对于左脚，11岁和13岁的孩子在一般年龄上存在差异（p = 0.024）。超重和肥胖组得分低于正常BMI组（p = 0.039; p = 0.001）。总的来说，这项研究中的脚被归类为正常，有内翻的倾向，尤其是男孩。11岁组和13岁组之间存在差异，在BMI方面，BMI正常的组得分更高。因此，青春期较高的身体质量指数并不代表足内翻。
Adolescence is marked by changes to the body, including the feet. The Foot Posture Index (FPI-6) stands out from other foot type classification methods as valid, reliable, and multidimensional. However, the current literature differs according to age group, with little consolidation of normative data in school children, largely due to the influence of such factors as sex, age and body mass index (BMI). Thus, this study assesses foot posture in adolescents according to age, sex and BMI. The study evaluated 1.394 adolescents from Amparo and Pedreira regions in São Paulo, Brazil. Subjects were positioned barefoot on a wooden base and each foot was assessed by FPI-6 criteria. Each criterion was scored on a scale of −2 to +2, negative for supinated and positive for pronated posture. Initially the data were assessed for normality using the Shapiro-Wilk test and descriptive statistics were calculated. To investigate and compare the scores of FPI-6 with regards to age and body mass index, analysis of variance (ANOVA) was used, followed by post hoc Tukey. To compare the FPI-6 with regard to gender, an independent student t test was used. All data were analyzed using SPSS version 21.0 and the 5% significance level. Boys had higher scores than girls (p = 0.037) for the right foot, and the group with normal BMI values scored higher than the obese group (p = 0.001). For the left foot, 11- and 13-year-olds differed (p = 0.024) with respect to age in general. The overweight and obese group scored lower than the normal BMI group (p = 0.039; p = 0.001, respectively). Overall, the feet in this study were classified as normal, with a tendency to pronation, particularly in boys. There were differences between the 11 and 13 year groups and, with regard to BMI, there were higher scores for the group with normal BMI. Therefore, a higher BMI in adolescence is not indicative of a pronated foot type.
