Aim: To investigate the association between subjective memory impairment (SMI) and objective cognitive impairment in later life, and to ascertain whether this is modified by level of social activity, education or living alone. Methods: Data were analyzed from three French community surveys carried out in Bordeaux, Dijon and Montpellier. Representative samples of 9294 residents aged 65years and over were included in the study. SMI was ascertained and investigated in relation to performance on the Benton Visual Retention Test (BVRT), the Isaac Set Test (IST) and Trail Making TestB (TMT). Adjustments were made for age, sex, education, depressive symptoms (Centre for Epidemiological Depression scale), site where study was carried out and living alone. Stratified analyses investigated modification by high or low social activity, education or living arrangement. Results: SMI was reported by 21.9% of the sample, and was significantly associated with lower scores on BVRT and TMT after adjustment for age, sex, education, depressive symptoms, site and living alone. These associations were not significantly modified by social activity, education or living alone. Conclusion: Worse subjective memory was associated independently with worse performance on two tests of cognitive function; however, in these cohorts, no evidence was found for modification of associations by social activity/support or education. © 2012 Japan Geriatrics Society.
