Healthy aging: how does a multidimensional construct of functional ability predict objective and subjective outcomes?

For subjective indicators, compared with the reference group, the risk of reporting a poor perceived health during the follow up was significantly higher in the low FA group (HR = 3.97 [95% CI: 1.85–8.53]), close to significance in the medium FA group (HR = 2.15, p = 0.063), but not different in the high FA group ( p = 0.706).

Second, our small sample size may also explain the fact that we did not reach statistical significance in intermediate levels of FA (medium and high) for some of the outcomes explored despite the high risks observed in these groups.
