Are changes in self-rated health associated with memory decline in older adults?
Abstract

Objective. The association between patterns of change in self-rated health (SRH) and memory trajectories in older adults was examined using a systematic approach.

Method. Data from the Health Retirement Study (N=6016) and the English Study of Ageing

(N=734) were analyzed. Individuals were grouped into five categories according to their pattern of change in SRH over eight years: stable excellent/very good/good, stable fair/poor, improvement, decline and fluctuating pattern without a trend. Memory was measured using immediate and delayed recall tests. Kruskal-Wallis, chi-squares tests, and linear mixed models were used to examine the association.

Results. Different rates of decline in memory can be identified in the different patterns of change in SRH. Those who had a stable excellent/very good/ good pattern had the slowest rate of decline.

Discussion. Our findings suggest that SRH status and patterns of change could be used as a marker of cognitive decline in prevention screening programs.
