Odds of Successful Aging – No Decline by Quartile of GVRS
We observed a dose response for increasing quartiles of GVRS. Compared to the highest quartile of GVRS (9.3+), the odds of successful aging without cognitive decline (SA-ND) were 1.50 (95% C.I. 1.03-2.19) times greater for the third quartile of GVRS, 1.63 (1.12-2.36) times greater for the second quartile, and 3.25 (2.13-4.94) times greater for the lowest quartile. Odds ratios in Model 1 are adjusted for length of time between baseline and follow-up cognitive testing only, and in Model 2 for years of education, health insurance status, and follow-up time.
