Abstract

This study investigated the prevalence of flatfoot in children with delayed motor development and the relevant factors affecting it. In total, 121 preschool-aged children aged 3-6 with delayed motor development (male: 81; female: 40) were enrolled in the motor-developmentally delayed children group, and 4 times that number, a total of 484 children (male: 324; female: 160), of gender- and age-matched normal developmental children were used as a control group for further analyses. The age was from 3.0 to 6.9 years old for the participants. The judgment criterion of flatfoot was the Chippaux-Smirak index >62.70%, in footprint measurement. The results showed that the prevalence of flatfoot in children with motor developmental delay was higher than that in normal developmental children, approximately 58.7%, and that it decreased with age from 62.8% of 3-year-olds to 50.0% of 6-year-olds. The results also showed that motor-developmentally delayed children with flatfoot are at about 1.5 times the risk of normal developmental children (odds ratio = 1.511, p= 0.005). In addition, the prevalence of flatfoot is relatively higher in overweight children with delayed motor development, and that in obese children is even as high as 95.8% (23/24). Children with both excessive joint laxity and delayed development are more likely to suffer from flatfoot. The findings of this study can serve as a reference for clinical workers to deal with foot issues in children with delayed motor development.
