Smoking, drinking, and other life style factors and cognitive function in men in the Caerphilly cohort.
To examine the cognitive function in a large, ongoing cohort study of older men, and to identify associations with social and lifestyle factors. ⋯ Age and social class show strong associations with cognitive function. Leisure persuits and social contact are also both positively associated. Neither tobacco smoking nor the drinking of alcohol seem to be associated with cognitive function, though there is evidence suggestive of self selection of both men who had never smoked and ex-smokers.
