| Annotation | Little is known about potential longitudinal relationships between participants for social, physical and intellectual activities and later cognitive performance. Data for 530 people aged 55-94 from the Victoria Longitudinal Study (VLS) in British Columbia, Canada were used to test whether baseline and change in lifestyle engagement were related to corresponding indicators of cognitive speed (measured by mean level and intra-individual variability). Regressions based on random effect model estimates showed that cross-sectional activity participation predicted corresponding values of both mean level and intra-individual variability, but few longitudinal variations were significant. Overall, a higher frequency of participation in cognitively complex activities was related to faster response times and lower intra-individual variability. Findings suggest that activity level at one point in time may be a more important predictor of cognition than an individual's change in activity level. (RH). |
