Figure 2. Using varimax rotation, 12 items on aging-related health and functioning yielded three exploratory factors (Factor 1, Factor 2 and Factor 3). The factor loading of each item within the explanatory factor is shown in (B–C). Factor 1, focusing on dietary uptake and physical performance, explained greater than half of the overall variance; Factor 2, focusing on tooth condition, explained 15.9% of the overall variance; and Factor 3, consisting only of perceived age, explained 10% of the overall variance. Notably, each item was considered to significantly contribute to the overall aging-related health and functioning (loading>0.5).
