elderly, blood lipid level, cognitive function and functional mobility


          The aim of this study was to investigate the correlation between body mass index (BMI) and cognitive function, cognitive function and functional mobility and to make comparisons between cognitive function and BMI of the elderly. There were 183 participants in this study. Participants were divided into 5 groups by BMI. [ The cognitive function was collected by Montreal cognitive assessment (MOCA) test and functional mobility was collected by Timed up and go (TUG) test. The correlation was analyzed using a Spearman correlation. The comparison of cognitive function between 5 groups was analyzed by using one-way Analysis of variance (ANOVA). The results showed that all of 5 groups had cognitive impairment (93.44%). Most of the elderly have an abnormal BMI (78.14%) and abnormal functional mobility (57.37%). The statistical analysis found the correlation between cognitive and functional mobility (r=-0.364). However, there was no correlation between body mass index and cognitive function, and no significant difference of cognitive function between the 5 groups (p=0.393). The results of this study indicated that body mass index is not related to cognitive function, but the elderly with cognitive impairment had slower movements. Therefore, they should be aware of proper care and a rehabilitation program.
