3.2. Regression results for life satisfaction
Results in Table 2 show that the old-old were more likely to
report higher life satisfaction than their young-old counterparts
(B = 1.34, p < 0.001) when controlling for other factors that
influence life satisfaction, including frailty and social vulnerability.
Moreover, frailty was negatively associated with life satisfaction
(B =
23.85, p < 0.001). In addition, the interaction between frailty
and age was also significant (B = 5.17, p = 0.011) (see Table 2).
Further tests show that the negative relationship between frailty
and life satisfaction was stronger among the young-old than the
old-old, which suggests that frailty might impose a stronger
impact on the young-old’s life satisfaction than that of the old-old.
