| Annotation | In this study a structural equation model of predictors of age differences in cognitive performance in late adulthood was developed. Biological markers of ageing (vision, hearing, vibration sense, forced expiratory volume, and grip strength) were used as indicators of a latent variable called BioAge. A sample of 180 community-dwelling women aged 60 to 90 was assessed. Results showed that BioAge explained all the age-related variance in cognitive test performance. Physical health and physical activity had direct effects on BioAge. Measures of acculturation explained non-age-related variance in cognitive test performance. Some variables used as biomarkers also explained individual differences in measures of crystallised intelligence and perceptual speed. The study concluded that the association between biomarkers and cognition in old age was due to more than a common statistical association with age. (AKM). |
