Arch Height Mediation of Obesity-Related Walking in Adults: Contributors to Physical Activity Limitations

Figure 3

CSI values (-axis) for each subject in every BMI classification group (-axis). Horizontal bars represent group means. Note that when controlling for BMI, CSI and navicular height are significantly correlated (, ) indicating a relationship between footprint and structural-based measurements for arch height. Five categories are used to create qualitative descriptions of arch height based on CSI: elevated, normal, intermediate, lowered, and flat [27]. Those with overweight BMI scores represented arch heights that were elevated (8.3%), normal (62.5%), intermediate (20.9%), and lowered (8.3%). Those with overweight BMI scores had elevated (4.3%), normal (39.1%), intermediate (52.3%), and flat (4.3%) arches. Subjects with obese BMI scores exhibited normal (31.8%), intermediate (31.8%), lowered (18.2%), and flat (18.2%) arch heights.
