| Annotation | The cross-sectional and longitudinal effects of history of smoking, alcohol use and engagement in exercise on cognitive performance were examined in a sample of 945 participants aged 65-98 from the Australian Longitudinal Study of Ageing (ALSA). Past smokers performed more poorly on tests of recall and speed of information processing at times 1 and 2 than those who had never smoked. Past smokers and moderate users of alcohol performed better on confrontation naming and working memory than those who had never smoked or drank alcohol. Engaging in exercise was related to immediate recall and speed of processing before, but not after, controlling for covariates. Health habits were not related to longitudinal changes in cognition. The results suggest a negative effect of history of smoking on effortful cognitive tasks and protective effect of alcohol use on more automatic cognitive tasks among older people. (RH). |
