Abstract

OBJECTIVE
To evaluate the relationship between body mass index (BMI) and foot parameters. METHOD: We examined 1, 107 feet of 872 volunteers (male: 325, female: 547) with 3D foot scanner (Nexcan , K & I, Korea). The relations of BMI and foot parameters were analyzed by partial correlation analysis with adjusted height. We classified subjects into 4 groups by BMI; low-weight (<18.5 kg/m2), normal-weight (18.5~22.9 kg/m2), over- weight (23.0~24.9 kg/m2) and obesity (>25 kg/m2) group. The relations of these groups and foot parameters were analyzed by univariate ANOVA with fixed height. RESULTS: Instep point length, ball width and girth, waist, instep height and girth, and vamp height showed a positive relation to BMI (p<0.01). However, foot parameters related to longitudinal length and medial longitudinal arch had no significant relation to BMI (p<0.01). Ball width and girth, waist, instep height and girth, vamp height were significantly highest in obesity group compared to the other groups (p<0.05). However, foot parameters related to longitudinal length and medial longitudinal arch showed no significant difference between these 4 groups (p>0.05). CONCLUSION: This study showed that BMI was positively related to height, width, girth of foot. But, BMI had no significant relation to length of foot, and medial longitudinal arch.
