Description

<p>The study aimed to investigate factors related to the characteristics of the lower arch of the foot using the arch height ratio calculated from the dorsum height and foot length. A nonlinear regression analysis, SVM-RFE, was conducted using low arch as the dependent variable and patient attributes as explanatory variables to identify factors related to lower arch of the foot. This survey recruited 1,178 community-dwelling participants (485 men, 693 women) in Japan. A questionnaire was administered, and the foot arch ratio was measured. There were 207 participants in the low arch group and 971 in the non-low arch group. Age, height, weight, foot length, and body mass index were used as explanatory variables. From the classification of explanatory variables by SVM RFE, age, foot length, and weight were identified as factors related to the foot arch. Although there were few explanatory variables in the present study, SVM RFE was an effective method for analysis of factors associated with lower arch of the foot.</p>
