Note: The model also included income quintiles, the change in self-rated health measure,

self-rated memory, self-reported neighborhood safety and measure of the continuity of care, none of which were statistically significant, and are not shown here due to space constraints. Their inclusion or exclusion did not alter the parameters shown in the table
