Dementia and Geriatric Cognitive Disorders Extra, 12(2), 90-93.http://hdl.handle.net/10400.13/5257We investigated the mediating role of leisure activity engagement as marker of cognitive reserve in the relation between neighborhood socio-economic position (SEP) and cognitive decline over 6 years. Methods: The study analyzed longitudinal data from 897 older adults who par ticipated in the two waves (2011 and 2017) of the Vivre-Leb en-Vivere (VLV) survey in Switzerland (M = 74.33 years in the first wave). Trail Making Test parts A and B were adminis tered in both waves. Leisure activity engagement was as sessed during interviews. Neighborhood SEP was derived from the Swiss Neighborhood Index of Socio-Economic Position (Swiss-SEP), provided by the Swiss National Cohort (SNC). Results: Latent change score modeling revealed that 42.5% of the relationship between higher neighborhood SEP and smaller cognitive decline was mediated via a higher frequency of leisure activities in the first wave. Conclusion: Neighborhood SEP constitutes an important contextual fac tor potentially influencing the pathways of cognitive reserve accumulation and, therefore, should be taken into account to better understand their effects on cognitive decline in old age.engCognitive declineCognitive reserveActivity engagementNeighborhood socio-economic positionOld ageLongitudinal study.Faculdade de Ciências Sociaisjournal article10.1159/000521905
