中国西南地区3～14岁儿童足部发育状态的横断面研究
Cross-sectional study on foot development in children in Southwest China
摘要
Abstract
Objective To establish reference ranges for foot morphology parameters in children aged 3-14 years in Southwest China and provide a basis for assessing the developmental status of children's feet.Methods A total of 3476 children aged 3-14 years(1918 boys and 1558 girls)from Southwest China were enrolled.Foot morphology was evaluated using the"Foot Secret"3D full-foot scanner,which measured foot pa-rameters,including arch volume,arch index,and foot length in both weight-bearing and non-weight-bearing states.Arch flexibility was calculated from arch volume under different conditions.Percentile ranges(P2 5-P97.5)were used to establish 95％reference intervals for arch volume,arch index,arch flexibility,and foot length to assess foot development.Results Foot length and arch volume increased with age,while arch index and arch flexibility decreased(P＜0.001).Reference ranges for foot length in boys and girls increased from 146.7-182.0 mm and 143.2-177.4 mm at age 3 to 227.9-279.7 mm and 209.1-250.2 mm at age 14,respectively.In the non-weight-bearing state,reference ranges for arch index decreased from 0.21-0.37(boys)and 0.20-0.37(girls)at age 3 to 0.15-0.33(boys)and 0.13-0.33(girls)at age 14.Under weight-bearing conditions,arch index decreased from 0.28-0.37(boys)and 0.27-0.37(girls)at age 3 to 0.21-0.35(boys)and 0.20-0.35(girls)at age 14.Arch volume in the non-weight-bearing state increased from 3 155.4-15 046.3 mm3(boys)and 2 948.9-11 547.0 mm3(girls)at age 3 to 13 998.8-40 494.1 mm3(boys)and 11 372.3-36 624.0 mm3(girls)at age 14.Under weight-bearing conditions,arch volume increased from 1 686.4-8 163.3 mm3(boys)and 1 801.1-7 481.7 mm3(girls)at age 3 to 7 043.7-31 661.1 mm3(boys)and 7 775.9-24 505.2 mm3(girls)at age 14.Arch flexibility in boys and girls decreased from 0.13-0.71 and 0.13-0.74 at age 3 to 0.05-0.53 and 0.06-0.55 at age 14,respectively.Conclusions This study established reference ranges for multi-dimensional foot parameters in children aged 3-14 years in South-west China,providing a valuable reference for assessing pediatric foot development.关键词
