Abstract
Although previous evidence has shown that diet is significantly correlated to some biomechanical foot parameters, especially gait velocity, little is known whether higher adherence to diet recommendations for older adults may be correlated with foot function, especially lower levels of peak plantar pressure. Therefore, the main purpose of the study was to explore if higher level of Elderly Dietary index score was correlated with lower peak plantar pressures. One-hundred and twenty older adults aged ≥60 years participated in this cross-sectional study. To assess the level of adherence to nutritional recommendations for older adults, we used Elderly Dietary Index score. Plantar pressures beneath the forefoot, midfoot and hindfoot regions of the foot were determined by pressure platform. Pearson’s coefficient of correlations and partial correlations were used to calculate the relationships. In unadjusted model, higher Elderly Dietary Index was significantly correlated with lower peak plantar pressure beneath the forefoot (r = - 0.45, p <0.001) a nd h indfoot ( r = - 0.37, p <0.001) region, while no significant correlation with peak plantar pressure beneath the midfoot region (r = -0.15, p=0.113) was observed. When we adjusted for age, body-mass index and gait velocity, higher Elderly Dietary Index remained significantly correlated with lower peak plantar pressure beneath the forefoot (r = -0.41, p<0.001) and hintfoot (r = -0.32, p<0.001) region. This study shows that higher adherence to nutritional recommendations is significantly correlated with lower forefoot and hindfoot peak plantar pressures in older women.
